Abstract

The application provides a cooling fin for a display screen and an electronic device. The cooling fin includes: a graphite sheet; and a thermal radiation adjusting film disposed on one surface of thegraphite sheet and provided with a plurality of micro-cavities on a surface away from the graphite sheet. In the cooling fin provided by the invention, the thermal radiation adjusting film is disposedon the upper surface of the graphite sheet, and the upper surface of the thermal radiation adjusting film has a plurality of micro-cavities. In this way, the area of the upper surface of the thermalradiation adjusting film that has a thermal insulation effect can be added, thereby reducing the heat conduction of the cooling fin in the thickness direction.

Description

technical field [0001] The present application relates to the technical field of heat dissipation, and in particular, the present application relates to heat sinks for display screens and electronic equipment. Background technique [0002] Nowadays, with the continuous development of mobile phones in the direction of ultra-thin and high performance, the high heat flux of the circuit board inside the mobile phone due to the enhancement of performance and the reduction of heat dissipation space has seriously affected the working performance and stability of the mobile phone. performance and service life, and may even threaten the personal safety of users. In particular, when a mobile phone is charging, playing games or playing videos, it will generate a lot of heat and cause the chip and body to overheat, which not only greatly damages the performance and life of the internal components of the mobile phone, but also greatly affects the user experience. Overheating may even ca...
