Abstract

A cooling system includes a first circulation pipeline unit and a second circulation pipeline unit that are configured to circulate a cooling medium. The first circulation pipeline unit includes a first water supply pipe group and a first water return pipe group that are connected to each other. The second circulation pipeline unit includes a second water supply pipe group and a second water return pipe group that are connected to each other. A first end of the first water supply pipe group and a first end of the first water return pipe group each are provided with a first expansion interface.
