Abstract

The invention relates to a heat dissipation structure of a wireless charging coil and a manufacturing method thereof. The heat dissipation structure of the wireless charging coil is characterized by comprising an insulating plate and filling glue filled in meshes of the insulating plate, and meshes which are evenly distributed are formed in the portion, making contact with the wireless charging coil, of the insulating plate. The insulating plate is made of an insulating material, and the filling glue is insulating glue with certain heat-conducting property; and the insulating plate is arrangedbetween the wireless charging coil and the magnetic core. According to the heat dissipation structure, the insulation requirement between the coil and the magnetic core is guaranteed, and the heat conduction performance between the coil and the magnetic core is improved; and the rigidity is ensured to meet the requirements, and the requirements of insulation and heat-conducting property are alsomet. The heat dissipation structure is high in machinability, easy to implement and quite convenient to install.

Description

technical field [0001] The invention relates to the technical field of coil heat dissipation, in particular to a heat dissipation structure of a wireless charging coil and a manufacturing method thereof. Background technique [0002] For outdoor wireless charging products, the coupling mechanism is the coil. In order to meet the waterproof and dustproof requirements, the general protection level must reach IP67 and above, and the heat of the coil must be transmitted through the magnetic core pasted on the aluminum shell. In the traditional heat dissipation structure, there is mostly 1mm or 2mm insulating material between the coil and the magnetic core. Most of the insulating materials have the characteristics of temperature resistance and heat insulation, and the thermal conductivity is extremely low, which cannot meet the heat dissipation requirements of the coil. During the operation of the wireless charging system, the coil A lot of heat is generated inside, and the insul...
