[0018] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1 As shown, the utility model is a server-level liquid cooling test verification device, including: a test shell, a liquid cooling test cycle component, a controller, a power distribution control module, a data acquisition module and a power supply module.

[0021] The server heating simulation module includes a plurality of server heating simulation elements 5; the server heating simulation elements 5 are connected in series to the pipeline; the server heating simulation elements 5 are used to simulate the heating and power consumption functions of the server.
