Abstract

The invention provides a cooling device, a battery and electronic equipment, and relates to the technical field of electronic products. The operating temperature of a system in the equipment can be reduced and the cooling effect is improved. The cooling device comprises a heat-absorbing material and a packaging cavity, wherein the specific heat capacity of the heat-absorbing material is greater than that of a heat-conducting material; the packaging cavity is enclosed by side walls; the heat-absorbing material is arranged in the packaging cavity; the material of each side wall of the packaging cavity is the heat-conducting material; the side walls of the packaging cavity are used for being connected with a heating device; and heat emitted from the heating device is transmitted to the heat-absorbing material. The cooling device is mainly used for cooling in the equipment.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a heat dissipation device, a battery and electronic equipment. Background technique [0002] The heat dissipation problem of electronic equipment has become one of the important factors restricting its development. Excessively high system operating temperature will lead to unstable operation of electronic equipment, so solving the system heat dissipation problem in electronic equipment has become a key point. [0003] Taking mobile terminal equipment such as smart phones and tablet computers as examples, more and more mobile terminal equipment adopt fast charging design. Among them, components such as charging interface, control circuit, battery connector and protection board circuit in mobile terminal equipment Serious heat will be generated in the charging mode. The traditional solution to the problem of heating of mobile terminal equipment generally uses heat-condu...
