Abstract

A heat dissipation magnetic insulation tape includes an insulating protective adhesive layer, a composite heat dissipation adhesive layer, and a magnetic insulation adhesive layer which are stacked. the composite heat dissipation adhesive layer is made of thin metal foil coated with heat dissipation graphene, which has good thermal diffusion performance. At the same time, compared with the traditional graphite sheet, the metal foil is not fragile, and no fragments will enter the equipment body. In addition, the metal foil also has excellent electromagnetic shielding function. The heat dissipation and magnetic insulation tape has the characteristics of excellent magnetic insulation effect, good heat dissipation performance and stable adhesion. A wireless charging power receiver includes theheat dissipation magnetic isolation tape, which is thin in thickness, excellent in heat dissipation magnetic isolation performance, stable in adhesion performance, and has high charging efficiency.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a heat dissipation and magnetic isolation tape and a wireless charging power receiver. Background technique [0002] Wireless charging technology uses the principle of electromagnetic induction, that is, changes in the surrounding magnetic field will cause current to be generated in the wire. In the 1890s, scientist Nikola Tesla demonstrated the possibility of wirelessly transmitting radio waves and filed the first patent. At present, there are four different commercial technologies for wireless charging: electromagnetic induction technology, radio wave technology and electromagnetic resonance technology, and electric field coupling technology. [0003] Several technologies have their own characteristics. Now the wireless charging technology in large-scale mass production is electromagnetic induction technology. In electromagnetic induction technology, the charging base (transmi...
