Description

Liquid cooling device

technical field

The invention relates to a heat dissipation device, in particular to a liquid cooling heat dissipation device which uses liquid in a liquid cooling system circuit to drive a fan.

Background technique

With the continuous advancement of technology, CPU performance and processing speed have also been continuously improved. When the computer is used for a long time and executes various applications, it will generate high heat that will affect the operation of the computer, making it more difficult to discharge heat generated by dense electronic components. Although a general computer has a built-in fan to adjust the internal temperature of the system, the heat dissipation effect is not good.

In order to improve the efficiency of heat dissipation, multiple heat sinks can be installed on the heating component to generate air convection, and then the fan can be used to dissipate the heat energy to generate hot and cold air convection. In addition, multiple heat sinks can be used. Pierce the heat pipe and connect the heat pipe to the water tank and the motor. After the cooling water is injected, the motor drives the cooling water to circulate in the water tank and the heat pipe to take the heat away from the heating element to improve the heat dissipation efficiency.

This kind of water-cooling system must use a motor to drive the liquid in the water-cooling circuit to circulate, and use a fan to drive the gas to cause airflow disturbances to take away the heat on the heat sink. The two have power sources and operate independently, thus generating higher Electromagnetic noise also keeps the manufacturing cost of the water cooling system high.
