Abstract

The invention provides a cooling system for a wireless charging device for an electric vehicle power battery, which can effectively dissipate the coil; the structure is simple and reasonable; the heatdissipating efficiency is high; the cooling system for a wireless charging device for an electric vehicle power battery comprises a heat conducting layer in contact with the coil; a heat dissipatingfin layer is further arranged on the rear side of the heat conducting layer and contacts with the heat conducting layer; the heat dissipating fin layer comprises a heat dissipation sheet; and the heatdissipation sheet is made of a phase change composite material.

Description

technical field [0001] The invention relates to the technical field of wireless charging for power batteries of electric vehicles, in particular to a cooling system for a wireless charging device for power batteries of electric vehicles. Background technique [0002] Such as figure 1 As mentioned above, the power battery wireless charging device for electric vehicles is composed of the ground terminal, which is the transmitter, and the vehicle terminal, which is the receiver. The transmitter takes power from the mains and undergoes AC / DC conversion, and then converts it into a high-frequency AC signal driven by DC / AC again. The excitation coil transmits energy. According to Faraday's law, the receiving end can receive corresponding energy through the excitation coil, and the received energy is rectified to charge the power battery of the electric vehicle. [0003] In the whole process of wireless energy transmission, because the coil has a certain resistivity, there will be...
