Detection device for liquid-cooled servers

Abstract

This application provides a testing device for a liquid-cooled servo. The testing device includes a liquid storage component, a heating component, and liquid piping. The liquid piping includes a first sub-pipe and a second sub-pipe. The first sub-pipe connects the outlet of the liquid storage component to the liquid-cooled servo, and the second sub-pipe connects the return port of the liquid storage component to the liquid-cooled servo. The liquid piping also includes a first switching valve, a first liquid delivery power component, an electric proportional valve, a first sensor assembly, and a second sensor assembly. The first switching valve, the first liquid delivery power component, the electric proportional valve, and the first sensor assembly are arranged sequentially along the flow direction of the liquid medium in the first sub-pipe, and the second sensor assembly is disposed in the second sub-pipe. The testing device not only improves the accuracy of liquid cooling testing but also facilitates subsequent component replacement and maintenance.
