Problems solved by technology

Although a number of partitions provided in the box can increase the heat exchange area with the cooling liquid, the box body itself is too small, and the heat exchange area it can provide will not be large
In addition, the heat absorbed by the box from the electronic components is mainly dissipated through the circulation of the liquid, and the heat dissipation speed is extremely limited
The device is not ideal for absorbing heat from the electronic components or dissipating heat outward
[0005] In addition, the aforementioned two patents both use pumps to drive the circulation of the cooling liquid in the cooling device. Not only does the pump itself require cost, but the work of the pump also requires external energy such as electric energy to drive, which increases the cost, and due to The use of pumps will inevitably cause noise problems

Abstract

The invention relates to a liquid cooling heat radiation device, which comprises a heat radiator contacting the heating electric element, a liquid storage bank containing the liquid and at least one heat pipe. Wherein, the liquid storage bank is independent from the heat radiator and mounted on the frame; one end of heat pipe is connected to the heat radiator, while another end is connected to the liquid storage bank and dipped in the liquid. The invention has simple structure, lower cost, less noise and better heat radiation effect.

Description

【Technical field】 [0001] The invention relates to a heat dissipation device, in particular to a liquid-cooled heat dissipation device for computer system heat dissipation. [Background Technology 1 [0002] With the increasing heat generation of electronic components such as central processing units and the miniaturization of electronic products, traditional heat sinks are restricted by various factors such as available space and cost, and it is difficult to greatly improve their heat dissipation performance. , while the noise problem is getting more and more attention. Therefore, as the heat dissipation problem of PC products is becoming more and more serious today, the new heat dissipation device using liquid as the medium has once become the darling of research and application in the field of heat dissipation due to its advantages such as low noise, and some liquids, such as water, have high specific heat and no pollution. Many advantages, such as low cost and so on, make...
