Abstract: A liquid storage tank includes a housing, a piston located in the housing, a cover, an elastic element, and an outlet pipe. The cover is attached to the housing and has a support post extending toward the piston. The piston, the housing, and the cover define a tank chamber. The tank chamber is filled with cooling liquid. The elastic element is connected with the tank hosing and the piston. The elastic element is free from contact with the cooling liquid. The outlet pipe communicates with the tank chamber. An extension direction of an opening of the outlet pipe is not parallel to a direction of movement of the elastic element. When the cooling liquid is decreased, the piston compressed the tank chamber such that the elastic element is released. The tank chamber is continuously compressed by pairing the elastic element and the piston.
