In order to find the best thermal management materials, battery manufacturers will usually choose the following two types of products: the liquid solidification thermal conductive caulking material or procuring thermal conductive gaskets.So, they have what different?
Let's first understand the difference of material and its application method.Caulking materials通常是通过计量混合的双组分体系，在两块基板中的一个上点胶，然后将两个基板压在一起以达到指定厚度，然后形成柔性固态界面。而另一种材料，导热垫片需要预先剪裁成所需的形状，贴到一个基板上，压合到指定厚度并固定，加载外力迫使固体变形，让导热垫片与粗糙的表面紧密贴合。
In order to understand these differences, we use a metal-Thermal interface materials-Comparison of the two metal sandwich structure188金宝搏网站登录LORD CoolThermProducts have the same thermal conductivity and thermal resistance of the commercialization of the thermal conductive gasket.
How did it go?We found that the thermal management materials have higher thermal impedance, while filled with high heat conductivity and small thickness.This is the material with one or two base material physical contact undesirable results.Results show that compared with the thermal conductive caulking glue, thermal conductivity gasket has higher interface thermal resistance.
In addition, with different thermal conductive gasket, caulking glue can flow into the tiny cracks, and closer contact with the surface.In the base material more effectively transfer heat between up and down.And caulking glue can adapt to different shape and thickness of the application, and the battery pack and the size of the base material of tolerance is everywhere.
Let's review.In addition to the key to compare these two types of material properties, due to the die cutting waste, lead to thermal conductive gasket cost is quite high.As we mentioned earlier, when using the caulking materials, heat transfer is the best, because they can be small gap into the rough surface.Using a thermal conductive gasket, because they can't reach those tiny gap, in air are more likely to remain.Caulking materials design is more flexible, can be mixed by adjusting the ratios change the hardness and the work time.Finally, when it comes to application products, large size thermal conductive gasket shape may be difficult to application, the inevitable form bubbles, and automatic production is difficult.Caulking material, on the other hand, very suitable for mass production.
Therefore, when looking for the best thermal management materials for battery, please consider using liquid caulking material, in order to obtain better thermal performance, and easy to assemble, low stress, applicable to different size, different clearance and lower cost.Contact us and learn more about Lord CoolTherm thermal conductive caulking material, and download ourCaulking materialswithThermal conductive gasket contrastThe white paper.
