Solution to heat dissipation of wireless charger
Wireless charging The technology breaks through the traditional connection line charging and uses intelligent power on transmission Wireless charging Technology, which improves the efficiency and convenience of charging. In 2017, after the mobile phone wireless charger was widely recognized, its utilization rate became higher and higher. It once became the initiating product in the mobile phone charging industry. Due to its small size, the working temperature of internal electronic components needs to be solved first
The thermal conductive silicone rubber pad has certain flexibility, excellent insulation, compressibility and natural viscosity on the surface. In order to use the design scheme of gap heat transfer, it can fill the gap, complete the heat transfer between the heating part and the heat dissipation part, and play the roles of insulation, shock absorption and sealing, To meet the design requirements of equipment miniaturization, heat-conducting silicon gasket is a heat-conducting medium that transmits the temperature of the heat source surface to the radiator and air. In order to improve the heat dissipation efficiency, the metal material at the bottom of the wireless charging is generally integrated with an anti-skid pad, which lays a good foundation for the heat dissipation of internal electronic parts and has the effect of anti-skid and not easy to wear.
Wireless charging The middle part of the internal coil is also the part where the heat is concentrated. Therefore, the main temperature probe is set between the coils to ensure that the service temperature of the charger is within the qualified temperature range. Remove the screws of the coil metal base plate, and you can see the internal structure of the product bottom shell. The bottom shell is formed by metal integration, which is also the key to heat dissipation. The use of metal is to conduct the heat inside the product through the bottom shell, so as to keep the internal working temperature in a qualified state and prolong the service life of the product.
Because the bottom plate is connected with the circuit board of the wireless charger, all components are concentrated on one side of the PCB, and the circuit board is irregular, so it can not be directly and seamlessly connected with the bottom shell. Therefore, the thermal conductive silicone foam and the thermal conductive foam cotton are placed on the bottom shell, and the gap between the bottom shell and the circuit board is filled. The heat of the circuit board is passed through the heat conduction of the heat conductive silica gel sheet and the thermal conductive foam cotton.
