The Role of Thermally Conductive Silicone Sheet for Heat Dissipation of New Energy Vehicles
New energy vehicles are the inevitable trend of future development, and the subsequent battery heat dissipation has attracted everyone's attention! Thermally conductive silicone sheet due to its own advantages:
The range of thermal conductivity and the stability, the structural workmanship are bridged, the process workmanship requirements of the radiator and the heat dissipation structure, the insulation performance, the shock absorption and sound absorption effect, the installation, the test, and the convenience of reusability are reduced. And get close attention.
Many people think that the application of thermally conductive silica gel in new energy vehicle batteries is related to the heat dissipation method of new energy vehicle battery packs (liquid cooling, air cooling, phase change cooling) or the packaging method of new energy vehicle battery packs (cylindrical battery). Battery packs, square battery packs, soft packs) are closely related. Some people even think that these different heat dissipation methods or the packaging methods of the battery pack completely determine the application of the thermally conductive silicone sheet. In fact, the thermally conductive silicone sheet is a passive heat dissipation medium, that is, It only plays a role of heat conduction in the battery pack, which has no direct relationship with the heat dissipation and packaging methods of these new energy vehicle battery packs. When the car is operating, the battery of a new energy vehicle is continuously discharged and charged. During the entire working process, the temperature of the battery pack of a new energy vehicle changes at any time, and this change is uneven, and local temperatures are often too high. Or partial cooling is uneven, and the uneven internal temperature of the battery pack needs to be solved immediately. This is when the thermal silicone sheet is needed, whether it is between the battery cell and the battery cell, or between the battery module and the battery module. Thermally conductive silicone sheet can be embedded between the battery module and the battery shell. As long as there is a temperature difference in any position, the thermally conductive silicone sheet can transfer the temperature from high temperature to low temperature through its good heat conduction, and do the best possible Reduce the temperature difference to a safe temperature. Therefore, regardless of whether the new energy vehicle battery is air-cooled or water-cooled, or cylindrical, square, or soft, thermally conductive silicone sheet is a omnipotent indispensable, the last medicine to ensure the safe operation of new energy vehicle batteries.
The thickness and hardness of the thermal conductive silicone sheet can be adjusted according to the design. Therefore, the heat dissipation structure can be bridged in the heat conduction channel. The flatness and roughness of the work difference, if the processing accuracy is improved, the product cost will be greatly increased. Therefore, the thermally conductive silicone sheet can fully increase the contact area between the heating element and the heat sink, and reduce the production cost of the heat sink. Therefore, the thermal conductive silicone sheet is a good filling for the heat dissipation of the new energy vehicle battery!
