In recent years, with the enhancement of people’s awareness of energy conservation and emission reduction, and in order to implement the strategic goals of “carbon peaking” and “carbon neutrality”, new energy vehicles with the advantages of no pollution, low noise and high energy efficiency have received more and more consumption. favored. As we all know, reducing the weight of the car can effectively reduce the emission of the car and improve the combustion efficiency of the car. As the most important component of new energy vehicles, the lightweight design of batteries has become an important development direction in the field of new energy vehicles in the future. At present, new energy vehicle batteries need to use thermally conductive silicone gaskets to dissipate heat, but the existing thermally conductive silicone gaskets with thermal conductivity above 1.5W/m.k generally have a density above 2.6g/cm3, which is difficult to meet the needs of lightweight vehicles.
Therefore, it is urgent to develop a lightweight, low-density, high-thermal-conductivity silicone gasket to meet the lightweight requirements of automobiles. The production process of low-density thermally conductive silica gel sheet is the same as that of ordinary thermally conductive silica gel sheet. It is a kind of thermally conductive medium material synthesized by a special process with organic silica gel as the base material and various auxiliary materials such as metal oxides added. It is worth mentioning that , the added metal oxide has been modified and optimized, the particle size of the modified metal oxide is smaller, and the produced thermally conductive silicone sheet has lower density and higher thermal conductivity.
This thermally conductive silicone gasket has the characteristics of low density and high thermal conductivity, which not only meets the needs of new energy vehicle battery heat dissipation efficiency, but also reduces the weight of the vehicle and achieves the purpose of saving energy.
So, what are the characteristics of this lightweight, low-density thermally conductive silicone sheet?
One. Low density:
Low-density thermally conductive silicone sheet has a lower density, which is a new type of thermally conductive product. Compared with traditional thermally conductive gaskets, this low-density thermally conductive silicone sheet is very different because it is a very light weight The thermally conductive silicone sheet is not only light and compact, but also light in weight. As a lightweight design, this regular low-density thermally conductive silicone sheet can be used in a variety of industries.
Two. Lower hardness:
The new low-density thermally conductive silicone sheet not only has low density, but also has low hardness. This kind of flexible thermally conductive silicone sheet is very convenient to use and install. Because of its good flexibility, it can be applied to a variety of small, light and thin This is an advantage that ordinary thermally conductive silicone sheets do not have.
Third. Deformation height:
Due to the low hardness and low density of the low-density thermally conductive silicone sheet, its deformation is relatively high, and it can be stretched at will, and its performance will not be affected or broken after changing actions. Therefore, the low-density thermally conductive silicone sheet with this characteristic has very strong tensile strength, operability and durability, so it is quite popular.
