Strictly Adhere To Military Standards - Light Weight, Small Size And Accurate Phase Change Temperature Of Aviation Extreme Heat Busting Materials: 90℃ Military Aviation Phase Change Materials

Basic product description:

• When the ambient temperature is lower than 90℃, the phase change material is in a solid state, and the internal atomic or molecular arrangement shows a relatively regular and tight lattice structure, and the interaction force between atoms or molecules is strong, making the material have a certain shape and volume stability.
• As the ambient temperature gradually rises and approaches 90°C, the material begins to absorb heat, and the thermal movement of atoms or molecules is intensified due to the acquisition of energy, which gradually weakens the original interaction force, the lattice structure begins to collapse, and the material gradually changes from solid to liquid.

The basic nature of the product:
 

-- Physical properties
1. In solid state

• The material has a certain strength and hardness, and can withstand the mechanical stress generated by aviation equipment during flight, such as vibration, impact and so on.
• At the same time, the solid phase change material has a low coefficient of thermal expansion, and will not produce excessive volume expansion or contraction due to temperature changes, which ensures its installation stability in aviation equipment.

2. In liquid form

• The fluidity of the material is good, and it can be fully filled into the gap and heat dissipation channel of the equipment to improve the efficiency of heat transfer.
• In addition, the liquid phase change material has a lower viscosity, which facilitates circulation and flow within the equipment, further enhancing its thermal management effect.
   

-- Chemical properties
1. High chemical stability

• In the military aviation environment, there may be exposure to various chemicals, such as jet fuel, lubricating oil, hydraulic oil, etc.
• 90℃ military aviation phase change materials have good chemical stability, can resist the erosion of these chemicals, will not occur chemical reaction or decomposition, to ensure its stable performance in complex chemical environments.

2. Strong oxidation resistance

• In high temperature and aerobic environment, the material is prone to oxidation reaction, which affects its performance and service life.
• After special treatment, the phase change material has strong oxidation resistance, which can maintain the stability of its chemical properties during long-term use and extend the service life of the material.

Common application scenarios of the product:
-- Protection of high-temperature components of aircraft engines
1. Turbine blades

• In aeroengines, turbine blades work in a harsh environment of high temperature, high pressure and high speed rotation.
• When the engine is working, the temperature of the turbine blades rises sharply. 90℃ military aviation phase change material can be coated on the surface of the turbine blade or made into a heat sink installed near the blade.
• When the blade temperature is close to 90℃, the phase change material changes from solid to liquid, absorbs a lot of heat, effectively reduces the blade temperature, and prevents material creep and thermal fatigue caused by overheating of the blade, thus extending the service life of the turbine blade.

2. Combustion chamber wall

• The temperature inside the combustion chamber is very high, and the heat generated by combustion will make the temperature of the combustion chamber wall rise rapidly.
• When the wall temperature is close to 90°C, the material absorbs heat, reduces the transfer of heat to the engine housing and other components, avoids the structural material around the combustion chamber wall due to high temperature damage, and also improves the thermal efficiency of the engine.
   

-- Avionics heat dissipation
1. High-power radar system

• In the electronics bay of an aircraft, high-power radar systems generate a lot of heat when they operate. The phase-change material is made into a cooling module, which is installed around heating components such as radar transmitters and power amplifiers.
• When the temperature of the device rises to about 90°C, the phase change material absorbs heat, so that the temperature of the device is kept within the appropriate working range, and the electronic components are prevented from performance degradation, failure or even burning due to overheating.
• This helps to improve the reliability and continuous operation of the radar system, for example, by extending the time between failures of the radar system by about 30% to 50%.

2. Electronic warfare equipment

• Electronic warfare equipment, such as electronic jammers, will generate a lot of heat during the working process.
• 90°C military aviation phase change materials can be used in the heat dissipation channels of these devices or inside the equipment housing. When the temperature reaches 90°C, the material absorbs heat to ensure the temperature stability of the electronic warfare equipment, maintain the accuracy of its signal transmission and reception, and improve the combat effectiveness of electronic warfare equipment in complex electromagnetic environments.
