A CPU cooling device based on Stirling engine

Abstract

The present invention relates to the technical field of CPU heat dissipation, and in particular to a CPU heat dissipation device based on a Stirling engine. The heat dissipation device includes a heat sink and a Stirling engine; the heat sink is set in a boss shape, the base end of the heat sink is a large end, and the fin end is a small end. The base end is used to connect with the CPU, and the fin end is connected to the heat absorber. surface connection; the Stirling engine includes a hot cylinder, the hot cylinder has a heat-absorbing surface, and the heat-absorbing surface is a concave surface adapted to the fin end. In the CPU heat dissipation device provided by the present invention, the heat sink is arranged between the CPU and the engine heat-absorbing surface to avoid direct contact between the CPU and the engine heat-absorbing surface, reduce heat accumulation on the CPU surface, and improve the heat dissipation effect. And the heat sink is designed in a boss shape. The big end can effectively absorb the heat emitted by the CPU, and the small end can reduce the heat dissipation area, so that more of the heat absorbed by the heat sink can be absorbed and utilized by the engine. The heat-absorbing surface of the engine matches the shape of the heat sink to improve heat-absorbing efficiency, thereby improving waste heat utilization.

Description

technical field [0001] The invention relates to the technical field of CPU heat dissipation, in particular to a CPU heat dissipation device based on a Stirling engine. Background technique [0002] With the development of science and technology, computers have become an indispensable tool in all walks of life, and the integration of computer CPUs is getting higher and higher. Highly integrated CPUs will generate a lot of heat when they work. Therefore, the CPU Heat dissipation and heat recovery have also become more and more people's concerns. [0003] Existing CPU heat dissipation methods include air cooling, water cooling, and heat dissipation devices based on Stirling engines. Among them, heat dissipation devices based on Stirling engines mostly realize heat exchange by directly contacting the hot cylinder with the CPU, resulting in the heat exchange between the CPU and the hot cylinder. Too much heat is accumulated on the contacting surface, thus resulting in poor heat ...
