It should be noted that the liquid pump 2 is arranged in the housing 1, which means that the liquid pump 2 is installed in the housing 1, and is not connected to the housing 1 through a pipeline. The inlet of the first thermostat is arranged at the first liquid inlet outlet 112a, that is, the inlet of the first thermostat is installed at the first liquid inlet outlet 112a, and is not connected through a pipeline. The outlet of the first thermostat is arranged at the first liquid outlet inlet 121a, that is, the outlet of the first thermostat is installed at the first liquid outlet inlet 121a, and is not connected through a pipeline. The first thermostat can be a heater 3 or a first heat exchanger 4. In one embodiment, the first thermostat is a heater 3, that is, the heater 3 and the liquid pump 2 are integrated in the housing 1. In another embodiment, the first thermostat is the first heat exchanger 4 , that is, the liquid pump 2 and the first heat exchanger 4 are integrated into the housing 1 .

[0065] The liquid cooling module provided in the present application is applied, by setting a shell 1, the shell 1 is formed with a liquid inlet cavity 11 and a liquid outlet cavity 12, the liquid pump 2 is arranged in the shell 1, the heater 3 or the first heat exchanger 4 is arranged between the liquid inlet cavity 11 and the liquid outlet cavity 12, the liquid pump 2 can pump the liquid at the load end to the liquid inlet cavity 11, and enter the corresponding heater 3 or the first heat exchanger 4 through the liquid inlet cavity 11, the liquid heated by the heater 3 or cooled by the first heat exchanger 4 flows back to the liquid outlet cavity 12, and flows back to the load end through the module outlet 122, completing a cycle.

[0066] In summary, the liquid cooling module provided in the present application integrates the liquid pump 2 and the heater 3 or the first heat exchanger 4 through the shell 1, and the inlet and outlet liquids of the heater 3 or the first heat exchanger 4 are integrated in the shell 1. When the liquid cooling system is assembled on site, there is no need to install the liquid pump 2 and the heater 3 or the liquid pump 2 and the first heat exchanger 4 and the corresponding inlet and outlet pipes, which reduces the number of components assembled on site of the liquid cooling system, simplifies the assembly process, reduces the overall material cost and assembly cost, and reduces the overall space occupancy.

When the first liquid inlet outlet 112a is opened and the liquid inlet valve outlet 112c is closed, the liquid in the liquid inlet chamber 11 enters the first thermostat through the three-way valve; when the first liquid inlet outlet 112a is closed and the liquid inlet valve outlet 112c is opened, the liquid in the liquid inlet chamber 11 enters the second heat exchanger 6 through the three-way valve.

That is, the liquid inlet cavity 11 is provided with the first liquid inlet outlet 112a and the second liquid inlet outlet 112b, the liquid outlet cavity 12 is provided with the first liquid outlet inlet 121a and the second liquid outlet inlet 121b, the inlet of the heater 3 is provided at the first liquid inlet outlet 112a, and the outlet of the first heat exchanger 4 of the heater 3 is provided at the first liquid outlet inlet 121a; the inlet of the first heat exchanger 4 is provided at the second liquid inlet outlet 112b, and the outlet of the first heat exchanger 4 is provided at the second liquid outlet inlet 121b. In this embodiment, the liquid inlet cavity 11 is provided with outlets corresponding to the heater 3 and the first heat exchanger 4, namely, the first liquid inlet outlet 112a and the second liquid inlet outlet 112b, so that the first heat exchanger 4 and the heater 3 are integrated into the shell 1, further reducing the number of components installed on site of the liquid cooling system and simplifying the assembly process. In addition, the first heat exchanger 4 and the heater 3 are both arranged in the shell, and there is only one leakage point between the inlet of the first heat exchanger 4 or the heater 3 and the shell 1, and there is only one leakage point between the outlet of the first heat exchanger 4 or the heater 3 and the shell. Compared with the first heat exchanger 4 and the heater 3 being connected to the liquid pump and the load through pipelines, there is a leakage point at each end of the pipeline. Therefore, the above-mentioned integrated setting reduces the number of leakage points and improves the reliability of the liquid cooling module. In some specific examples, the second liquid outlet inlet 121b can also be connected to the liquid injection and drainage pipe 101.

[0071] In order to control the flow rate of the liquid inlet chamber 11 entering the heater 3, the heater 3 includes a heater body and a valve connected to the heater body, such as a switch valve or a flow valve, that is, the heater body and the valve for controlling its flow rate are integrated into the housing 1. The valve can control the flow rate of the liquid in the liquid inlet chamber 11 that flows through the heater body and flows into the liquid outlet chamber 12, thereby achieving precise adjustment of the outlet liquid temperature. Exemplarily, a flow valve is provided between the outlet of the heater body and the liquid outlet chamber 12, or a flow valve is provided between the inlet of the heater body and the liquid inlet chamber 11, and the flow valve is used to adjust the flow rate of the liquid flowing from the liquid inlet chamber 11 through the heater body into the liquid outlet chamber 12, so that the liquid in the liquid inlet chamber 11 partially enters the heater body and partially enters the first heat exchanger 4 according to a suitable ratio, thereby achieving precise adjustment of the outlet liquid temperature, or the liquid in the liquid inlet chamber 11 does not flow into the heater body but all enters the first heat exchanger 4. In another example, a switch valve may be provided between the outlet of the heater body and the liquid outlet chamber 12, or between the inlet of the heater body and the liquid inlet chamber 11, and the switch valve may control the connection between the heater body and the liquid inlet chamber 11 or the liquid outlet chamber 12. It is understandable that, without providing the valve for controlling the flow of the heater body, the outlet temperature of the first heat exchanger 4 may be adjusted so that the temperature of the liquid flowing into the liquid outlet chamber 12 meets the requirements.
