Liquid cooling server

The invention discloses a liquid-cooled server, relates to the technical field of liquid-cooled heat dissipation, and can prevent waste heat of a radiator from generating heat influence on an operation element so as to improve the overall heat dissipation efficiency of the liquid-cooled server. The liquid-cooled server comprises a casing, a first operation element and a cooling module; the shell is provided with an air outlet; the first operation element is arranged in the machine shell; the cooling module comprises a first cold plate, a liquid cooling pipeline, a pump, a radiator and a fan; the first cold plate is in thermal contact with the first operation element and is used for performing heat exchange on the first operation element; the liquid cooling pipeline is connected to the first cold plate and used for conveying heat conduction fluid; the pump is connected to the liquid cooling pipeline and is used for pumping the heat-conducting fluid; the radiator is connected to the liquid cooling pipeline and
