The invention belongs to the technical field of cooling, and in particular relates to a liquid injection and discharge device. The liquid injection and drainage device of the present invention includes: a high-pressure gas source, a liquid storage tank, a first pipeline, a second pipeline and a third pipe; the first pipeline is provided with a first valve, which communicates with the high-pressure gas source and the liquid storage tank; A second valve is arranged on the second pipeline to communicate with the coolant pipeline in the liquid storage tank and the electrical equipment; a third valve is arranged on the third pipeline to communicate with the high-pressure gas source and the coolant pipeline in the electrical equipment; when the first valve and the coolant pipeline in the electrical equipment The second valve is opened, the third valve is closed, and the high-pressure gas generated by the high-pressure gas source can be injected into the liquid storage tank through the first pipeline, so that the cooling liquid in the liquid storage tank is injected into the cooling liquid pipeline through the second pipeline; When the first valve is closed, the second valve and the third valve are opened, and the high-pressure gas generated by the high-pressure gas source can be injected into the cooling liquid pipeline of the electrical equipment through the third pipeline, so that the cooling liquid in the cooling liquid pipeline moves along the second Line vents to reservoir.
Description
technical field [0001] The invention belongs to the technical field of cooling, and in particular relates to a liquid injection and discharge device. Background technique [0002] As more and more electrical equipment uses liquid cooling technology to dissipate heat, it is necessary to inject cooling liquid into the electrical equipment and to allow the cooling fluid in the electrical equipment to be discharged. A liquid injection and drainage device (application number 201210539552.0) is disclosed in the prior art. The liquid injection and drainage device is used to inject cooling liquid into electrical equipment and drain residual cooling liquid in the electrical equipment. In the disclosed solution, the first pump is used to inject the cooling liquid in the first storage tank into the electrical equipment, and the air compressor is used to repeatedly discharge all the cooling liquid remaining in the electrical equipment into the second storage tank. The system operation ...
