1. Description of phase transition characteristics

• The material's phase change temperature is precisely set at 45 ° C.
• When the ambient temperature is below 45 ° C, the material presents a relatively stable initial phase state, which may appear as a solid form, or have a specific microstructure arrangement. Once the ambient temperature climbs to the critical value of 45 ° C, the material will immediately start a rapid phase transition process, in this process, it can absorb a lot of heat, the common form of phase transition from solid to liquid, of course, there are other types of phase transition situations such as special changes in crystal structure.
• Crucially, this phase transition process is reversible. When the temperature drops, the material gradually releases the previously stored heat and returns to its original phase. With this property, the material is able to efficiently store and release heat in a temperature range of about 45 ° C, which is of great significance for the precise temperature control of military aviation equipment, and plays a very key hub role.

2. Analysis of conductivity

• Its thermal conductivity is precisely regulated within the appropriate range.
• If the thermal conductivity is high, it may cause the heat transfer speed to be too fast, so that the phase change material can not fully display its unique advantages of heat storage, which leads to the temperature fluctuation of the equipment is too large and the change is too drastic, and ultimately has an adverse effect on the normal and stable operation of the equipment.
• On the contrary, if the thermal conductivity is too low, it will seriously hinder the efficiency of the material to absorb and release heat, so that it can not accurately adjust the equipment temperature in a timely and effective manner.
• It is through the precise control and optimization of thermal conductivity that the material can accurately absorb and release heat at the right time node, so that it can work closely with other components in the aviation equipment to achieve high-quality and efficient thermal management goals.

Application Advantages:
1. Precise temperature control

• The use of this 45°C PCM material in military aviation equipment enables precise and efficient regulation of the temperature of the equipment. For example, in the avionics compartment of an aircraft, a variety of complex electronic components and systems need to operate at the right temperature to ensure their performance and reliability.
• The 45°C PCM material can absorb or release heat through the phase change process when the temperature is close to 45°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 flight environment

• Military aircraft experience a variety of complex environments and changes in operating conditions during flight. The 45°C PCM material can adapt to different altitudes, speeds, outside air temperatures, and more. 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 heats up, it can absorb the heat and maintain the temperature of the equipment at about 45°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, 45°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.
• 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 compartment of military aircraft, a large number of electronic equipment and lines are concentrated. The 45°C PCM material can be installed on the inner walls of equipment bays, partitions, and housings of electronic devices. When the electronics run hot and the cabin temperature approaches 45°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. Adjustment of aircraft cockpit environment

• The cabin environment of a military aircraft is critical to the productivity and physical health of pilots. The 45°C PCM material can be applied to the interior materials of the cockpit, such as seats, control panels, bulkheads, etc.
• When the cabin temperature is close to 45°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 systems

• For the various weapon systems carried by military aircraft, temperature control is critical to the performance and safety of the weapon. The 45°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 and bombs, this PCM material can improve its storage life and combat performance in different environments, ensuring that the weapon can accurately hit the target and exert maximum power at critical moments.
