Abstract

The invention relates to a heat dissipation structure of a wireless charging coil and a manufacturing method thereof. The heat dissipation structure of a wireless charging coil is characterized in that it includes an insulating plate and filling glue filled in the mesh holes of the insulating plate; the insulating plate and the wireless charging coil The contact parts form uniformly distributed mesh holes; the insulating plate is made of insulating material, and the filling glue is insulating and has a certain thermal conductivity; the insulating plate is arranged between the wireless charging coil and the magnetic core. The heat dissipation structure of the present invention not only ensures the insulation requirements between the coil and the magnetic core, but also improves the thermal conductivity between the coil and the magnetic core; it not only ensures that the rigidity meets the requirements, but also meets the requirements for insulation and thermal conductivity. The heat dissipation structure of the invention has strong machinability, is easy to implement, and is very convenient to install.

Description

technical field [0001] The invention relates to the technical field of coil heat dissipation, and in particular, to a heat dissipation structure of a wireless charging coil and a manufacturing method thereof. Background technique [0002] In outdoor wireless charging products, the coupling mechanism is the coil. In order to meet the requirements of waterproof and dustproof, the general protection level should reach IP67 and above, and the heat of the coil should be transferred through the magnetic core pasted on the aluminum shell. In the traditional heat dissipation structure, the insulation material between the coil and the magnetic core is mostly 1mm or 2mm. Most of the insulation 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 large amount of heat is generated ins...
