This work is about a liquid cooling device, especially a liquid cooling device with a pump structure.

The liquid cooling system includes components such as a cold plate, a pump and a connecting pipe, and the circulating pipeline is filled with a working fluid (usually water). According to this, the water-cooled head is brought into contact with the heat source to take away heat, and at the same time, the working fluid in the circulation pipeline is driven by a water pump to circulate, so that the working fluid flows through the water-cooled head and conducts heat exchange, so as to achieve the purpose of heat dissipation.

However, the water flow pressure that can be increased by the pump pressure or head of a single pump is limited, and the cooling system efficiency will be reduced when the pump fails. In addition, the existing electronic devices often need to set up a plurality of heat dissipation modules to dissipate heat from a plurality of heating elements inside. In addition, the heat dissipation modules inside the general electronic equipment are usually set independently, and each heat dissipation module is only provided with a single water pump and a single water cooling head, and dissipates heat from a single heat source. Since these heat dissipation modules require more connection pipes, the cooling system occupies more space, so it is necessary to further plan the heat dissipation design of the liquid cooling system to meet the needs of use and improve the overall heat dissipation of the liquid cooling system. efficiency.

The water inlet pipe is connected to the water inlet of one of the outermost water blocks in the series of water blocks. The water outlet pipe is connected to the water outlet of the other outermost water block among the series connected water blocks. The water inlet water pump is arranged on the water inlet pipe.
