Abstract

The invention discloses a heat radiation structure for an electronic component. The heat radiation structure comprises a shielding shell, two mute fans, a heat conduction rubber layer and a heat conduction metal sheet; a PCB plate is arranged in the shielding shell; the PCB plate is provided with the electronic component; one mute fan is arranged on the top of the shielding shell and the other mute fan is arranged in the position of a diagonal line of the side part of the shielding shell to form air convection; the heat conduction rubber layer is arranged on the top of the electronic component; the heat conduction metal sheet is arranged on the top of the heat conduction rubber layer; a heat conduction groove is formed in the heat conduction metal sheet; and the heat conduction groove is formed by a plurality of metal strips arranged in parallel. By adoption of the structure and due to the setting of the heat conduction groove in the conduction metal sheet, the heat conduction structure is light in weight, large in heat conduction contact area, and rapid in heat conduction; meanwhile, the two mute fans can take away the heat absorbed by the heat conduction metal sheet in the convection manner; and in addition, due to the setting of the shielding shell and the heat conduction rubber layer, the electronic components can be separated mutually in heat conduction without causing signal interference.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation structure for electronic components. Background technique [0002] Since the invention of electronic components, they have been used more and more in modern industry and modern life. For modern industry, especially mining, chemical industry, electric power, industrial manufacturing and other fields. For example, the electronic components attached to the PCB will generate thermal effects while working, and the temperature will continue to rise. If the heat is not taken away in time, it will cause heat accumulation and temperature rise, and eventually burn out the electronic components themselves and other components on the PCB board, or may affect the normal operation of the PCB board. [0003] At present, the heat dissipation methods of electronic components mainly include: heat conduction, convection and radiation. Heat conduction refers to the transfer of heat f...
