Customized For The Harsh Conditions Of Military Aviation - The Core Thermal Control Master To Ensure The Efficient Operation Of Flight Critical Systems: 45 ° C Military Aviation PCM

Product Introduction:

• In physical form, whether it is solid or liquid, it has good adaptability.
• It has certain structural strength and stability when it is solid, and can withstand mechanical effects such as vibration, shock and pressure changes in aviation flight.
• When it is liquid, it shows appropriate fluidity and heat conduction performance to ensure the effective transfer and distribution of heat.
• The chemical properties are extremely stable, and it can withstand the erosion of chemical substances such as fuel oil, lubricating oil and hydraulic oil common in the aviation field.
• It is also highly resistant to harsh environmental factors such as high humidity, strong radiation and extreme temperature changes, ensuring reliable performance in long-term and complex military aviation applications.

Nature of the product:
1. High latent heat

• Phase change materials will absorb or release a lot of latent heat during the phase transition process, and 45℃ military aviation phase change materials are no exception.
• The higher latent heat means that it is able to store or release more energy when the temperature changes, thus regulating the temperature more efficiently.
• This is very helpful for the operation of military aviation equipment in some extreme temperature environments, able to provide sufficient heat reserves or absorb excess heat.

2. Appropriate specific heat capacity

• In addition to having a high latent heat, its specific heat capacity is also more suitable.
• Specific heat capacity refers to the heat absorbed or emitted by increasing or decreasing the temperature of a substance per unit mass by 1 ° C. The appropriate specific heat capacity can ensure that the phase change material will not absorb or release heat too quickly during the temperature change process, making the temperature control more stable and accurate.

Common application scenarios:
-- Aero-engine thermal management
1. Temperature control of turbine components

• In aeroengines, turbine components work in a harsh environment of high temperature and pressure.
• 45 ° C military aviation phase change materials can be used near turbine blades or turbine disks. When the engine is working, the temperature of the turbine parts rises sharply, and when it is close to 45 ° C, the phase change material begins to absorb heat, changing from solid to liquid, preventing the temperature of the parts from being too high, avoiding thermal fatigue and the deterioration of material performance.
• For example, in the turbine blade cooling system of a high-performance fighter engine, the use of this phase change material can reduce the blade surface temperature by 10-20%, effectively extending the service life of the turbine blade.

2. Lubricating oil temperature regulation

• Engine oil temperature is too high will lead to its performance decline, affect the lubrication and heat dissipation effect.
• The phase change material is installed around the lubricating oil road, when the oil temperature is close to 45 ° C and has a rising trend, the material absorbs heat, maintains the lubricating oil temperature within the appropriate range, ensures that the engine components are well lubricated and cooled, and reduces the probability of mechanical failure caused by too high oil temperature.

-- Avionics bay
1. Heat dissipation of high-temperature electronic components

• In the avionics cabin, some high-power electronic components (such as power amplifiers, radar transmitters, etc.) will generate a lot of heat during operation, making the local temperature rise rapidly.
• The phase change material is made into a heat sink or packaged in the electronic component shell, when the temperature reaches about 45 ° C, the material undergoes a phase change to absorb heat and prevent the electronic component from being damaged due to overheating. This helps to improve the reliability of electronic devices.
• For example, it is possible to extend the time between failures of electronic devices by about 30-50%.

2. Ambient temperature adaptation

• The aircraft flies in some high-temperature environments (such as low-altitude, tropical flight), and the temperature in the electronic equipment compartment may exceed the normal operating temperature range.
• 45℃ military aviation phase change materials can stabilize the cabin temperature by absorbing heat, create a suitable working environment for electronic equipment, and ensure the stability of equipment performance.
