55 Military Aviation PCM It Releases Heat And Maintains A Stable Temperature In The Equipment Compartment

Appearance and physical characteristics:

• It may be available in a variety of suitable forms, such as flakes to cover large areas, granules to be used as filler mixes, and blocks to be used for installation in specific structural parts. Its appearance color is usually an inconspicuous color that meets military standards, which may be dark gray or dark blue, which not only helps to maintain overall coordination in aviation equipment, but also adapts to the requirements of concealment and other aspects in military applications to a certain extent.
• In terms of physical properties, it has a suitable mechanical strength. Due to the need to withstand vibrations, shocks, and different air pressures during aircraft flight, the PCM material needs to be strong enough to be resistant to breakage or deformation due to the need to withstand multiple stresses such as vibration, shock, and different air pressures during aircraft flight. Its density has been carefully designed to ensure good thermophysical performance without increasing unnecessary load on the aircraft due to excessive weight, affecting flight performance and fuel efficiency.
• At the same time, it has good insulation, can effectively prevent the accidental conduction of current, ensure the electrical safety of aviation equipment, and has a certain corrosion resistance, and can maintain long-term stability in the complex environment of aviation, such as contact with different chemicals.

Thermal Properties:
1. Phase change characteristics

• The phase change temperature is precisely set to 55°C. When the ambient temperature is below 55°C, it is in a relatively stable phase, which may be solid or has a specific microstructure, at this time its thermophysical properties are relatively stable, and the absorption and release of heat is relatively small. When the temperature rises to 55°C, it undergoes a rapid phase change and begins to absorb a large amount of heat, usually from a solid to a liquid state (or other forms of phase change, such as a change in crystal structure).
• This phase transition process is reversible, when the temperature drops, it will gradually release the stored heat and return to the original phase, so as to achieve efficient storage and release of heat, and play a role in regulating the temperature of the surrounding environment.
• The latent heat of the phase transition is large, which means that it is able to absorb or release a large amount of energy in a relatively small range of temperature changes around 55°C. In the field of military aviation, some critical equipment and components can generate heat during operation, and when the ambient temperature is close to 55°C, the PCM material can quickly absorb heat, prevent equipment from overheating, and ensure its stable performance and accuracy.
• For example, some avionics, some sensors around the engine, etc., can release heat when the temperature is low, so as to avoid problems such as performance degradation and start-up difficulties due to low temperature.

2. Thermal conductivity

• Its thermal conductivity is in the right range. If the thermal conductivity is too high, it may lead to too fast heat transfer, and the phase change material cannot give full play to its advantages in storing heat, so that the temperature of the equipment changes too drastically, affecting the normal operation and accuracy of the equipment.
• If the thermal conductivity is too low, it will affect its efficiency of absorbing and releasing heat, and the temperature of the equipment cannot be adjusted in time and effectively. By precisely controlling the thermal conductivity, the material is able to absorb and release heat at the right time, working in tandem with other components of aviation equipment for good thermal management.

Application Advantages:
1. Accurate temperature control ability

• The use of this 55°C PCM material in military aviation equipment enables precise and efficient regulation of the temperature of the equipment. For example, in some of the aircraft's critical electronic equipment bays, a variety of complex electronic components and systems need to operate at the right temperature to ensure their performance and reliability.
• The 55°C PCM material can absorb or release heat through the phase change process when the temperature is close to 55°C, so that the temperature in the equipment compartment is always kept within a relatively stable range, improving the reliability and service life of the equipment. It can effectively reduce equipment failures and misoperation caused by temperature fluctuations, which is essential for ensuring flight safety and mission execution.

2. Adapt to the complex and changeable military aviation environment

• Military aircraft experience a variety of complex environments and changes in operating conditions during flight. The 55°C PCM material can adapt to different altitudes, speeds, outside air temperatures, etc. When the aircraft is flying in a high-altitude and low-temperature environment, the PCM material can release the stored heat and prevent the temperature of the equipment from getting too low; When the aircraft is flying at low altitude and high speed or the temperature of the equipment itself is heating up, it can absorb the heat and maintain the temperature of the equipment at about 55°C.
• This adaptive thermal management capability ensures that military aviation equipment can operate normally in a variety of complex flight conditions, improving the aircraft's environmental adaptability and mission execution flexibility.

3. Improve equipment performance and life, and reduce maintenance costs

• With precise temperature control, 55°C PCM materials can significantly improve the performance and longevity of military aviation equipment. For some high-precision sensors, communication equipment, etc., stable temperature can ensure its measurement accuracy and signal transmission quality.
• At the same time, a suitable temperature environment can reduce the thermal stress and thermal fatigue inside the equipment, and reduce the aging rate and failure rate of the equipment. For example, for some key electronic components on an aircraft, long-term operation at the right temperature can extend their service life by about 20%-30%, reduce the cost of equipment maintenance and replacement, and improve the overall reliability and economy of military aircraft.
• Moreover, the use of this material can also reduce the reliance on additional cooling equipment, reducing the overall weight and energy consumption of the aircraft.

Application Scenarios:
1. Thermal management of avionics

• In the avionics bay of military aircraft, 55°C PCM can be installed on the inner walls of the equipment bay, partitions, and housings of electronic equipment. When the electronics run hot and the cabin temperature approaches 55°C, it begins to absorb heat, preventing the device from overheating. At the same time, when the aircraft flies to a low temperature area or the equipment stops operating and the temperature drops, it can release heat, maintain the temperature stability in the equipment compartment, and protect the electronic equipment from temperature changes.
• For example, for critical electronic systems such as radar systems, communication equipment, and navigation equipment of aircraft, this PCM material can ensure reliable operation in different flight phases and environmental conditions, improving the performance and stability of the equipment.

2. Temperature regulation of engine and peripheral components

• In the engine compartment of an aircraft, the operation of the engine generates a lot of heat, and some of its surrounding components, such as sensors, oil pipes, etc., need to work within the right temperature range. The 55°C PCM material can be applied to these areas, absorbing heat and preventing the part from overheating as the temperature rises closer to 55°C.
• When the engine stops running or the temperature drops, it can release heat to keep the components within the right temperature range, ensure the performance and reliability of the engine and surrounding components, and reduce the failure and damage caused by temperature problems.

3. Optimization of aircraft cockpit environment

• The cabin environment of a military aircraft is critical to the productivity and physical health of pilots. 55°C PCM materials can be applied to interior materials in cockpits, such as seats, control panels, bulkheads, etc.
• When the cabin temperature is close to 55°C, it regulates the temperature and provides a comfortable working environment for the pilot. In hot climates, it can absorb heat and reduce cabin temperatures; In cold high-altitude environments, it also releases heat and keeps the cabin warm. In addition, it can reduce the unevenness of the temperature in the cockpit and improve the thermal comfort of the pilot, which in turn improves the pilot's concentration and operational accuracy.
