Liquid-cooled server chassis

A liquid-cooled server chassis, comprising:

• a case;
• one or more liquid-cooling modules, each liquid-cooling module comprising a housing, a gas outlet valve, and a liquid return valve, wherein the gas outlet valve and the liquid return valve are opened during operation of the liquid-cooling module, and the liquid-cooling module accommodates a single server and is filled with coolant during operation;
• a connector configured to connect the liquid-cooling modules to a power supply;
• and
• a circulation portion comprising a gas outlet pipe, a liquid return pipe, a vapor processing part, and a liquid collecting part,
• wherein:
• the gas outlet pipe is connected to the gas outlet valve of each liquid-cooling module and is configured to transfer gas from the liquid-cooling module to the vapor processing part;
• the liquid return pipe is connected to the liquid return valve of each liquid-cooling module and is configured to transfer liquid from the liquid collecting part to the liquid-cooling module;
• the vapor processing part is connected to the gas outlet pipe and includes a condenser, the condenser being configured to condense vapor into condensed liquid by cooling the vapor in the vapor processing part;
• and
• the liquid collecting part is disposed below the vapor processing part and connected to the liquid return pipe, and configured to collect the condensed liquid from the vapor processing part.
