Problems solved by technology
At present, the battery cell surface of the automotive power battery assembly module is designed to be wrapped with a layer of PET film or not. Due to the tolerances between the stacked cells, even there will be air gaps between the cells that cannot be seen by the naked eye. , There is a burr gap between two objects, which means that the heat conduction ability is weakened; because the heat conduction putty has good heat transfer performance, high insulation performance, and at the same time has high temperature, no oil separation, no dry solid, no solidification, no melting, odorless, non-toxic and non-toxic Corrosive materials, high and low temperature resistance, water resistance, ozone, weather aging resistance, good thixotropy, moderate consistency, convenient use, simple coating or potting process, etc.; previous industries used thermal conductivity putty with different thermal conductivity to fill the gap between the cells The disadvantage is that there is silicone oil overflowing and it is easy to solidify over time, causing "silicon" pollution; there may be "bubbles" swimming on the interface that affect thermal conductivity; there is no elasticity and no bonding strength, and it needs to be equipped with solid parts; in order to meet both Thermal phase thermal conductivity of the product, superior high temperature resistance, radiation resistance and superior dielectric properties as well as high elasticity and bonding strength, thermal conductive silicone grease can be used, but due to mechanical vibration during processing or during product service The high-fluidity silicone grease will be subjected to the force of gravity acceleration to change the thermal phase material; therefore, the structure of the module can only be solved on the structure to solve the problem of gravity acceleration
