Application of Thermal Silicone Pad in Fast Charging Source Adapter
Although the fast charging source adapter can charge quickly, there is also a problem: the heating problem is serious. The working time of more than two hours was originally reduced to less than one hour. This improves the charging efficiency, but it is also accompanied by an increase in heat generation. If the heat generation problem is too serious, it may cause the adapter to burn.
In order to effectively solve the heat generation problem of the fast charging source adapter, it is necessary to guide the heat to the shell as soon as possible to reduce the temperature. The internal space of the fast charging source adapter is very narrow, so there is air, which reduces the heat transfer efficiency and is not conducive to heat. Therefore, it is necessary to fill a thermal silica gel sheet between the heat source and the heat sink.
thermal silicone pad is one of the more commonly used traditional thermal conductive materials. It is a kind of soft silicone as the base material, and a thermal silicone pad made of a certain proportion of thermally conductive, temperature-resistant, and insulating materials. It has high thermal conductivity, low thermal resistance, insulation, resistance to cold and thermal shocks, etc., it acts between the heating element and the radiator, fills the gap between the interface and removes the air from the interface, reduces the contact thermal resistance, improves the thermal conductivity, and at the same time can provide insulation, shock absorption, and sealing.
By filling the pits between the gaps, the air is removed and the contact thermal resistance is reduced, so that the heat source and the heat sink can be in close contact, thereby improving the heat transfer efficiency, so that the heat can be quickly transferred from the heat source to the outside to ensure fast charging, the performance and reliability of the source adapter.
