Integrating Cutting-Edge Technology And Demonstrating Excellent Phase Change Properties - The Shining Star Driving The Innovation Of Military Aviation Temperature Control: 25°C Military Aviation PCM

Product introduction:

• The latent heat of phase transition of military aviation phase change materials is usually high, which means that a large amount of heat can be absorbed or released during the phase change process.
• It plays a key role in temperature control, energy storage and release of military aviation equipment, and provides strong support for ensuring the efficient, stable and safe operation of military aviation equipment.

Advantages:
1. High energy storage density

• Phase change materials can absorb or release a lot of heat during the phase change process, and 25 °C military aviation phase change materials can store more energy in a relatively small volume.
• This is very important for military aircraft with limited space, which can effectively reduce the weight and volume of equipment, improve the load capacity and fuel efficiency of the aircraft.

2. Precise temperature control

• The material undergoes a phase transition at around 25 °C and is able to effectively absorb or release heat near this temperature point, thereby keeping the ambient temperature relatively stable.
• In military aircraft, this is essential for the proper operation of temperature-sensitive components such as electronics, instruments and instruments to prevent equipment failure or performance degradation due to too high or too low temperatures.

3. High reliability

• After rigorous screening and testing, it has good chemical stability and thermal stability, and can work stably in complex aviation environments for a long time.
• For example, including high temperature, low temperature, high altitude, strong vibration and other harsh conditions to ensure the safe flight of aircraft.

4. Reusable

• The phase change process is reversible, the material can continuously absorb and release heat in the process of temperature change, repeated use without performance attenuation, reducing the cost of use and maintenance difficulty.

Product application scenarios:
1. Avionics bay

• By keeping the temperature around the device stable, the material can effectively extend the service life of electronic devices.
• For example, in the electronic equipment bay of some high-performance fighter aircraft, the mean time to failure (MTBF) of the electronic equipment can be improved by about 30% to 50% after the use of phase change materials, significantly improving the reliability and combat effectiveness of the avionics system.

2. Aircraft fuel system

• The temperature of aircraft fuel has a great influence on the fluidity and combustion performance of the fuel.
• During flight, fuel temperature may fluctuate due to thermal radiation from the engine, changes in ambient temperature and other factors.
• The phase change material is installed on the inner wall of the fuel tank or around the fuel pipeline, when the fuel temperature is close to 25 °C and has a rising trend, the material absorbs heat, prevents the fuel temperature from being too high, and avoids the increase of fuel evaporation loss and the occurrence of unstable combustion.
• When the fuel temperature drops, the phase change material releases heat to maintain the fuel temperature within a suitable range, ensuring that the fuel can be normally supplied and burned.

3. Aviation cabin environment regulation

• In some emergency situations, such as when the cabin air conditioning system partially fails, phase change materials can play an emergency temperature regulation role, release heat to maintain the temperature in the cabin within a certain period of time to maintain the appropriate range, for the pilot to gain more response time, to ensure flight safety.

4. Helicopter blade anti-icing deicing

• Helicopter blades tend to freeze when flying in cold weather or at high altitudes.
• A heating channel containing 25℃ phase change material is designed inside the blade or an anti-icing coating containing phase change material is coated on the surface of the blade.
• When the blade temperature is below 25 °C and there are signs of icing, the phase change material is transformed by heating or using external heat, and the heat released can prevent the formation of ice or melt the ice that has been formed.

5. Uav thermal management

• By stabilizing the device temperature, battery performance deteriorates and device power consumption increases due to overtemperature.
• Phase change materials can extend the endurance of the UAV to a certain extent. In the application tests of some small reconnaissance drones, the endurance time of the drones can be extended by about 10%-20% after the use of phase change materials.
