Fusion Of Cutting-Edge Innovative Technologies - Thermal Control Star Showing Extraordinary Phase Change Properties At 45 °C And Escorting Aviation Safety: 45 °C Military Aviation PCM
The basic working principle of the product:
- When the ambient temperature is lower than 45℃, the phase change material is in a solid state, and the internal molecular arrangement is relatively regular and tight, and the intermolecular force is strong.
- As the ambient temperature gradually rises and approaches 45 °C, the material molecules begin to absorb heat, and the thermal motion of the molecules is intensified, gradually breaking the original intermolecular force and lattice structure, and then beginning to transform from solid to liquid.
Basic features of the product:
1. Precise phase transition temperature
- The phase transition temperature of this kind of phase change material is accurately controlled at about 45℃, which makes it able to accurately carry out phase transition in a specific temperature range, so as to achieve precise control of temperature.
- This precise phase change temperature characteristic is critical for military aviation equipment, which requires extremely high temperature control and requires materials to function stably at specific temperature points.
2. Good thermal conductivity
- It has good heat conductivity and can quickly absorb and release heat. This enables the phase-change material to respond quickly when the temperature changes, and to carry out the phase transition in time, improving the efficiency and timeliness of temperature control.
- Good thermal conductivity can also ensure that the heat is evenly distributed inside the material, avoiding the occurrence of local temperatures that are too high or too low, further improving the effect of temperature control.
3. High chemical stability
- In the military aviation environment, it will be exposed to various chemicals, such as fuel, lubricating oil, hydraulic oil, etc., and may also be affected by harsh environmental factors such as high humidity and strong radiation.
- 45℃ military aviation phase change materials have high chemical stability, can withstand the erosion of these chemicals, and maintain the stability of its performance under harsh environmental conditions, not easy to decompose, metamorphic and other chemical reactions.
4. Good reversibility
- The phase transition process has good reversibility and can be carried out several times under the condition of repeated temperature changes, and the performance of each phase transition changes little.
- This ensures the reliability and stability of phase change materials in the long-term use process, and can meet the requirements of military aviation equipment for long life and high reliability of materials.
Common application scenarios:
-- Missile launch systems (in the context of military aviation)
1. Temperature control of launcher
- The missile launcher will generate a lot of heat during operation, especially in continuous launch or high temperature environment.
- 45℃ military aviation phase change materials can be used in key parts of the launch device, such as guide rails, electrical control units, etc.
- When the temperature is close to 45 ° C, the material absorbs heat to ensure that the temperature of the launcher is within the safe range to prevent the accuracy and reliability of the missile launch from being affected by excessive temperature.
2. Heat dissipation of electronic guidance system
- The electronic guidance system of the missile is sensitive to temperature, and overheating will lead to signal transmission errors and guidance accuracy decline.
- The application of phase change materials in the cooling structure of guidance system can absorb heat and ensure the normal operation of guidance system when the temperature rises to 45℃, which is of great significance for improving the hit rate of missile.
-- UAV power system and equipment bay
1. Motor and battery temperature regulation
- In military drones, motors and batteries are key components.
- The motor will heat up at high loads, and the battery will also generate heat during charging and discharging.
- The phase change material is used in the motor housing and battery compartment, when the temperature reaches 45 ° C, the material absorbs heat, prevents the motor from overheating and damage, while extending the service life of the battery, and improving the endurance and flight safety of the UAV.
2. Onboard equipment cooling
- The onboard equipment of the UAV (such as the flight control system, communication equipment, etc.) also needs to work within the appropriate temperature range.
- 45℃ military aviation phase change materials can help maintain the temperature stability of these equipment, avoid equipment failure due to high temperature, and ensure the normal flight mission of the UAV.
