Cooler

Abstract

The invention provides a cooler which can be used for electronic devices. The cooler comprises a radiating unit, a fan unit, a metal sunshield and a first electronic unit, wherein the fan unit, which is arranged on one side of the radiating unit, comprises a shell and a fan; the fan encloses an open space for containing the fan; the metal sunshield shields part of the open space, so that the metal sunshield and the shell commonly surround the fan; one side of the open space is communicated with the radiating unit, so that the fan can blow air to the radiating unit; the metal sunshield shieldsthe first electronic unit to prevent the first electronic unit from being subjected to electromagnetic interference, and a through hole is formed in the part which shields the open space; the first electronic unit is positioned on one side of the metal sunshield; and the radiating unit and the fan unit are positioned on the other side of the metal sunshield.

Description

【Technical field】

[0001] The present invention relates to a cooling device; specifically, the present invention relates to a cooling device used in an electronic device, which cools the electronic device in a way of dissipating heat. 【Background technique】

[0002] Many electronic devices such as integrated circuits, transistors, etc. will experience temperature rise during operation, and the temperature rise will often affect the working curve of the electronic device, and even cause burnout or explosion of the electronic device in severe cases. Especially for electronic devices with high power or high operating frequency, the former such as power transistors and the latter such as central processing units (Central Processing Unit, CPU), often generate quite high temperatures under normal operating conditions.

[0003] Today's electronic devices are designed to be light, thin, short, and small in appearance, especially portable electronic devices such as notebook computers,...
