I. Basic Concept of High and Low Temperature Linear Module

High and low temperature Linear Module typically consist of multiple components, including a refrigeration system, heating system, temperature sensors, and a control system. Their working principle is based on the transfer and control of heat, enabling them to adjust the ambient temperature to a preset value within a short time to accommodate various experimental or testing needs.

Working Principle

The core working principle of high-low temperature Linear Modules is heat exchange. The process can be divided into the following steps:

Refrigeration Process: The refrigeration system of a high-low temperature Linear Module generally uses components such as a compressor, condenser, and evaporator. After initiating the cooling mode, the refrigerant is compressed into a high-temperature, high-pressure gas in the compressor, then passes through the condenser where it releases heat and turns into a liquid. The liquid refrigerant passes through an expansion valve, where its pressure drops before entering the evaporator. At this point, the refrigerant absorbs heat from the surrounding environment and evaporates back into a gas, thereby lowering the temperature of the surrounding medium.

Heating Process: When the Linear Module requires heating, heat is provided by heating elements (such as electric heating wires or heating plates). The control system monitors the internal temperature of the Linear Module. Once the temperature is detected to be below the set value, the heating elements are activated to quickly raise the ambient temperature to the required level.

Temperature Monitoring and Control: Temperature sensors are responsible for real-time monitoring of temperature changes within the module and transmitting this data to the control system. The system adjusts the intensity of cooling or heating based on the set value, thereby achieving precise temperature control.

Motors achieve low outgassing in vacuum environments primarily through material selection, manufacturing processes, and specialized designs aimed at reducing or capturing the release of internal gases. The following are key technologies and measures for implementing vacuum motors:

Material Selection: Low Outgassing Materials

Structural Materials: Use low-outgassing metals or inorganic materials such as stainless steel and ceramics, avoiding high-volatility materials like plastics and rubber.

Insulating Materials: Employ vacuum-grade insulating materials like polyimide and polytetrafluoroethylene (PTFE) to minimize the release of organic gases.

Lubricants: Use vacuum-compatible lubricants such as perfluoropolyether (PFPE) or molybdenum disulfide, avoiding the volatilization of traditional greases.

Adhesives and Sealants: Choose low-outgassing sealants like epoxy resins and silicones.

Manufacturing Processes: Reducing Contaminants

Cleaning Processes: Utilize ultrasonic cleaning and plasma cleaning to remove oils and particles.

Vacuum Baking: Perform high-temperature vacuum baking (e.g., 150–300°C) on components before assembly to pre-release gases.

Oxygen-Free Encapsulation: Assemble in an inert gas environment to reduce adsorbed gases.

Specialized Design: Isolating Gas Release

Sealed Design:

Fully Sealed Motors: Use metal welding or ceramic seals to completely isolate internal gases.

Vented Design: Utilize microporous structures for slow gas release, preventing sudden outgassing from affecting vacuum levels.

Internal Adsorption Design: Place getters (e.g., zirconium-aluminum alloy) inside the motor to actively adsorb residual gases.

Thermal Management Optimization: Heat dissipation is challenging in vacuum environments. Design effective thermal conduction paths (e.g., metal substrates) to prevent overheating and material outgassing.

Testing and Validation

Outgassing Rate Testing: Measure the motor's Total Mass Loss (TML) and Collected Volatile Condensable Materials (CVCM) using mass spectrometers.

Long-Term Vacuum Operation Testing: Simulate actual operating conditions to ensure motor stability in a vacuum.

Application Scenarios

Spacecraft: Attitude control motors, solar array drive motors.

Vacuum Equipment: Motors for semiconductor coating machines, particle accelerators, and vacuum pump drives.

Scientific Instruments: Precision adjustment motors for electron microscopes and space telescopes.

Challenges and Considerations

Lubrication Challenges: Lubricants can easily volatilize or solidify in a vacuum, necessitating space-grade lubrication solutions.

Heat Dissipation Limitations: The absence of convective cooling requires reliance on thermal conduction or radiation design.

High Costs: Low-outgassing materials and specialized processes increase manufacturing costs.

Through the comprehensive measures outlined above, motors can achieve low outgassing in vacuum environments, meeting the stringent requirements of high-vacuum systems for gas release and ensuring long-term, stable operation of equipment.

To optimize heat dissipation for Linear modules in high and low temperature environments, a comprehensive approach must be taken across five dimensions: material selection, structural design, heat dissipation methods, temperature control, and environmental adaptability. The specific strategies are as follows:

1、High Thermal Conductivity Materials and Interface Optimization

Core Material Upgrades

Use aluminum nitride (AlN, thermal conductivity ~200 W/m·K) or graphene composite materials as substrates, replacing traditional alumina ceramics to improve thermal conductivity by over 5 times.

Select interface materials such as thermal paste (thermal conductivity ≥3.3 W/m²·K) or thermal gel (≥3 W/m²·K), ensuring the contact area between the module and the heat sink covers at least 70% of the chip area to eliminate air gaps (thermal conductivity of air: ~0.026 W/m·K).

Low-Temperature Environment Adaptation

Use solid-state electrolytic capacitors instead of liquid capacitors to avoid performance degradation at low temperatures. Increase startup capacitor capacity or add parallel MLCCs (multilayer ceramic capacitors) to enhance startup current in low temperatures.

Select wide-temperature-range components (e.g., chips operating from -40°C to 125°C) to prevent performance degradation in low temperatures.

2、Innovative Heat Dissipation Structural Design

Heat Pipe and Vapor Chamber Technology

Heat pipes should adopt a flattened design (thickness ≥1.5 mm), avoiding excessively small bending radii (recommended R ≥ 3 times the heat pipe diameter) to minimize thermal resistance.

Vapor chambers (VCs) use internal conductive textures to expand the heat exchange area, allowing heat from high-temperature areas to be uniformly conducted in vapor form.

Fin and Airflow Optimization

Fins should be oriented in the direction of the fan airflow to reduce wind resistance. The number and height of fins should be adjusted based on power density.

Design independent airflow channels to ensure cold air flows through the core area of the module and hot air is efficiently expelled.

3、Active Heat Dissipation and Intelligent Temperature Control

Multi-Mode Heat Dissipation Systems

Air Cooling: Use axial fans or blower fans (centrifugal blowers) with dynamically adjustable speeds based on temperature.

Liquid Cooling: For high-power Linear modules, adopt a "cold plate + circulation pump" system that uses phase-change fluid cycles to dissipate heat, improving efficiency by over 50% compared to air cooling.

Hybrid Cooling: Combine heat pipes, fins, and fans to achieve efficient heat dissipation.

Intelligent Temperature Control

Embed negative temperature coefficient (NTC) thermistors or digital temperature sensors to monitor chip temperature in real time.

Dynamically adjust loads or heat dissipation strategies based on temperature thresholds.

4、Enhanced Environmental Adaptability

Protection Against Extreme High and Low Temperatures

High Temperatures: Allow sufficient temperature margins for components and select high-temperature-tolerant devices. Use multiple devices in parallel to distribute heat and avoid single-point overheating.

Low Temperatures: Use low-temperature solder to ensure reliable solder joints even below -40°C. Avoid concentrated thermal stress by dispersing heat sources in PCB layouts and reducing mechanical stress damage caused by material expansion and contraction.

Protective Structure and Sealing Design

Module housings should use stainless steel materials with fully sealed structures, achieving electromagnetic shielding effectiveness (SE) of ≥40 dB to withstand strong interference in the 30 MHz–1 GHz frequency range.

Critical interfaces should use waterproof connectors (IP65 rating) and shock-absorbing pads (silicone material) to withstand vibrations of 10–2000 Hz and 10g acceleration, preventing loose connections or chip solder joint detachment.

5、Simulation and Testing Verification

Thermal Simulation Optimization

Use software such as FloTHERM for transient thermal analysis to simulate the thermal distribution of Linear modules at different temperatures and optimize heat dissipation structures.

High and Low-Temperature Aging Tests

Place Linear modules in high-low temperature test chambers and perform cyclic tests from -40°C to 85°C to verify their startup performance, output stability, and lifespan under extreme temperatures.

The performance differences between high/low temperature Linear modules (typically referred to as industrial-grade or wide-temperature-range modules) and ordinary Linear modules (typically consumer-grade or commercial-grade modules) stem from their distinct design goals and intended operating environments.

Simply put, high/low temperature Linear modules sacrifice peak performance and power efficiency in exchange for stability, reliability, and long-term lifespan under extreme temperatures.

Below is a detailed comparison across several key dimensions:

1. Operating Temperature Range (The Core Difference)

Ordinary Linear Modules: Typically designed to operate within the commercial temperature range of 0°C to +70°C. This covers the environment for most consumer electronics (e.g., phones, computers, home appliances).

High/Low Temperature Linear Modules: Have a much wider operating temperature range, commonly including:

Industrial Grade: -40°C to +85°C

Automotive Grade: -40°C to +105°C (or even higher, with more stringent requirements)

Military/Aerospace Grade: -55°C to +125°C or wider.

Some specialized Linear modules can even operate in cryogenic environments below -100°C or high-temperature environments above +200°C.

2. Performance Stability and Reliability

Ordinary Linear Modules: Perform to specification within their rated temperature range. Performance can degrade sharply outside this range, potentially leading to timing errors, data loss, or even physical damage (e.g., electrolytic capacitor failure). Their design lifespan is typically a few years.

High/Low Temperature Linear Modules:

Low-Temperature Performance: At extremely low temperatures, carrier mobility in standard semiconductors decreases, reducing performance. These Linear modules employ special circuit design, component screening, and material selection to ensure normal startup and operation.

High-Temperature Performance: At high temperatures, component leakage current increases and heat dissipation becomes difficult, which can lead to thermal runaway. These Linear modules use high-temperature-resistant semiconductor processes, highly stable passive components (e.g., tantalum capacitors, ceramic capacitors), and rigorous thermal design.

Thermal Cycling Endurance: They must withstand repeated shocks from extreme cold to extreme heat, posing a significant challenge to the integrity of solder joints and packaging materials. They undergo strict thermal cycling tests.

3. Component Screening and Manufacturing Process

Ordinary Linear Modules: Use commercial-grade chips and components with standard production processes aimed at reducing cost and increasing yield.

High/Low Temperature Linear Modules:

Chip Level: Use industrial-grade, automotive-grade, or military-grade core chips (e.g., MCUs, memory, power ICs). These chips undergo stricter testing and screening at the wafer production stage to eliminate units with poor performance under extreme temperatures.

Component Level: Use exclusively wide-temperature-range passive components (resistors, capacitors, inductors), connectors, and PCB materials (e.g., high Tg laminates).

Process Level: May employ Conformal Coating for protection against moisture, corrosion, and salt spray. Higher standards for soldering processes are required to prevent cold joints.

4. Peak Performance and Power Consumption

Ordinary Linear Modules: To pursue high performance (high clock speed, high bandwidth, low latency), they often use more advanced manufacturing processes and aggressive power designs, offering the best experience at room temperature.

High/Low Temperature Linear Modules: Often operate at "downclocked" speeds or use more conservative designs.

Advanced processes can suffer from increased leakage current at high temperatures, so sometimes more mature but stable processes are preferred.

To control total power consumption and heat generation at high temperatures, their rated maximum operating frequency (e.g., CPU clock speed) may be lower than that of their consumer-grade counterparts.

In short: At room temperature, an ordinary module of the same technology generation may outperform a high/low temperature module in terms of speed.

5. Cost and Price

Ordinary Linear Modules: Cost-effective, competitively priced.

High/Low Temperature Linear Modules: Highly expensive. Reasons include:

The wide-temperature-range chips and components themselves are costly.

More complex material management and production processes.

Extremely rigorous testing (thermal cycling, extended burn-in, etc.) increases time and capital costs.

Their price can be several times to tens of times higher than that of ordinary Linear modules.

Application Scenario Comparison

Ordinary Linear Modules: Indoor electronics, office equipment, personal consumer electronics, general networking equipment.

High/Low Temperature Linear Modules:

Industrial: Outdoor industrial control, automation equipment (e.g., polar research stations, steel plants), power inspection, oil & gas exploration.

Automotive: Engine Control Units (ECUs), in-vehicle infotainment systems, autonomous driving sensors (mounted outside the vehicle, exposed to heat and cold).

Military/Aerospace: Satellites, missiles, radar, field communication equipment.

Medical: Certain in-vitro diagnostic equipment, low-temperature storage monitoring.

Outdoor: Base stations, surveillance cameras (outdoor models), drones (used for polar or desert research).

Summary Table

Conclusion:

The choice of module depends entirely on the application scenario. If your device operates in a climate-controlled indoor environment, ordinary Linear modules offer the best value. If your device needs to be deployed in a desert in summer, the Arctic in winter, a moving vehicle's engine bay, or the harsh environment of space, then high/low temperature Linear modules are fundamental to ensuring system survival and functionality. Their value far exceeds what performance specifications alone can measure.

In the HVAC industry, screw-type air-cooled heat pumps are known for their stable performance and high efficiency, making them ideal for medium to large-scale cooling applications. However, they are not suitable for every project size. To truly benefit from their performance and efficiency, the system’s cooling capacity must reach a certain threshold — below which the investment may not be cost-effective, and above which the screw compressor’s advantages fully emerge.
