Abstract

Embodiments of the present invention disclose a heat dissipation apparatus and an electronic device. The heat dissipation apparatus comprises a thermoelectric generator, a heat sink and a first element. The heat sink comprises a cold end and a heat end. A first end of the thermoelectric generator is fitted with and connected with the heat end of the heat sink and is used for absorbing heat of the heat end of the heat sink. A second end of the thermoelectric generator is fitted with the cold end of the heat sink so as to form a temperature difference between the second end and the first end. The thermoelectric generator is used for converting the temperature difference between the first end and the second end into a voltage, and outputting the voltage to the first element, so that the first element runs based on the voltage.

Description

technical field [0001] The heat dissipation technology of the present invention specifically relates to a heat dissipation device and electronic equipment. Background technique [0002] The cooling method of the central processing unit (CPU, Central Processing Unit) in the existing electronic equipment usually uses fluid (such as air or liquid) to absorb and carry the heat generated by the CPU to the outside of the electronic equipment. This approach does not recycle the heat generated by the CPU. If there is such a solution, recover the heat generated by the CPU, generate electricity based on the recovered heat, and generate electricity to drive a fan to cool the heat source. However, in the prior art, there is no relevant technical solution. Contents of the invention [0003] In order to solve the existing technical problems, the embodiments of the present invention provide a heat dissipation device and electronic equipment. [0004] In order to achieve the above obje...
