The 20°C Military Aviation PCM Can Store Energy, Absorb Heat, And Prevent Equipment From Overheating

Appearance and physical characteristics:

• It usually comes in a more regular shape, which may be plate, block or granular, etc., in order to adapt to different installation and use needs. Its appearance color is generally dark or non-reflective color in line with military standards, which can reduce the light reflection in aviation equipment on the one hand, and also has a certain degree of concealment on the other hand.
• In terms of physical properties, it has a certain hardness and toughness. Due to the mechanical effects such as vibration and impact during aviation flight, the material needs to have sufficient mechanical strength to ensure that it does not break or deform in various harsh environments.
• Its density has been carefully designed and optimized to meet the requirements of aviation equipment for lightweight, so as to reduce the load of the aircraft, improve flight performance and fuel efficiency, and ensure that it has good thermophysical properties.
• At the same time, it has good corrosion resistance and oxidation resistance, and can maintain stable performance and long-term reliable use in aviation environments, including exposure to various chemicals and different humidity and air pressure conditions.

Thermal Properties:
1. Phase change characteristics

• The phase change temperature is precisely set at 20°C. When the ambient temperature is below 20°C, it is in a relatively stable phase, which may be a solid state or a specific crystal structure, etc. When the temperature rises to 20°C, the material begins to undergo a phase change, absorbing a lot of heat and transitioning from one phase to another, such as from a solid to a liquid state (or a change in crystal structure).
• This phase change process is reversible, and when the temperature drops, it releases the stored heat again and returns to its original phase. This allows it to efficiently store and release heat around 20°C, which plays a key role in the temperature regulation of military aviation equipment.
• The latent heat of phase change is large, which means that it is able to absorb or release large amounts of energy within a relatively small range of temperature changes. In the field of military aviation, some key equipment such as avionics, optical instruments, etc., are very sensitive to temperature changes.
• When the temperature around the device is close to 20°C, the PCM material can quickly absorb heat, prevent the device from overheating, and maintain the operation of the device in the appropriate temperature range, ensuring stable performance and accuracy. When the temperature is low, it can release heat, avoiding problems such as performance degradation and difficulty in starting the equipment due to low temperatures.

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.
• 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. Precise temperature control

• The use of this 20°C PCM material in military aviation equipment enables precise and efficient regulation of the temperature of the equipment. For example, in the cockpit of an aircraft, various instruments and electronics need to operate at the right temperature to ensure that pilots can accurately access information and operate equipment.
• The 20°C PCM material can absorb or release heat through the phase change process when the temperature is close to 20°C, so that the temperature in the cockpit is always kept within a relatively stable range, improving the reliability of the equipment and the operating comfort of the pilot. 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 complex flight conditions

• Military aircraft experience a variety of complex environments and changes in operating conditions during flight. It is able to adapt to different altitudes, speeds, outside air temperatures, and other conditions. 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.
• And when the aircraft is flying at low altitude and high speed or the temperature of the equipment itself rises, it can absorb the heat and maintain the temperature of the equipment at about 20°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

• With precise temperature control, 20°C PCM materials can significantly improve the performance and service life 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.

Application Scenarios:
1. Thermal management of avionics compartment

• In the electronic equipment compartment of military aircraft, a large number of electronic equipment and lines are concentrated. The 20°C PCM material can be installed on the inner wall of the equipment compartment, partition and other parts, and when the electronic equipment runs and heats up the cabin temperature close to 20°C, it begins to absorb heat and prevent the equipment 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 aircraft communications equipment and navigation equipment, this PCM material ensures reliable operation in different flight phases and environmental conditions.

2. Aircraft cockpit environment adjustment

• The cabin environment of a military aircraft is critical to the productivity and physical health of pilots. The 20°C PCM material can be applied to the interior materials of the cockpit, such as seats, control panels, etc.
• When the temperature in the cockpit is close to 20°C, it is able to regulate the temperature and provide 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.

3. Thermal protection of aviation weapon system

• For the various weapon systems carried by military aircraft, temperature control is critical to the performance and safety of the weapon. The 20°C PCM material can be used for temperature regulation of the weapon compartment and thermal protection of the weapon itself.
• When the temperature of a weapon rises during flight due to air friction, chemical reactions, etc., the PCM material absorbs heat to prevent dangerous situations such as explosion or performance degradation caused by overheating of the weapon.
• During the storage and preparation of weapons for launch, it can also maintain the weapons within the appropriate temperature range, ensuring the reliability and combat effectiveness of the weapons. For example, for weapons such as missiles, bombs, etc., this PCM material can improve its storage life and combat performance in different environments.
