Background

With the progress of technology, computer hardware is gradually developed in the high-speed and high-frequency directions to improve the execution efficiency, and compared with the prior art, the heat energy generated by electronic components in the computer hardware is more considerable; for example, the solid state disk (Solid State Drive) is used as an access device in a computer host, and besides miniaturization of the volume design, the operation speed is greatly increased, so that the heat generated during the operation is considerable, and therefore, a heat dissipation device is required to reduce the working temperature. However, since the development of the solid state disk is fast in recent years, the access speed of consumers in electronic competition is satisfied, and as the solid state disk tends to develop at high speed and high frequency, the heat energy generated by the operation of the solid state disk is also rapidly increased, and the continuously rising working temperature tends to affect the operation efficiency of the solid state disk, so that the heat dissipation efficiency of the existing heat dissipation device is poor, and the heat energy generated by the solid state disk is difficult to be dissipated.

In view of the above, there is a need for an improved integrated liquid cooling system.
