Product Details
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.
