Product Details
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.
