Claim 8:
9. A liquid storage tank, comprising:
a housing;
a cover attached to the housing;
a piston in the housing and comprising a support post that extends toward the cover, wherein the piston, the housing, and the cover define a tank chamber, and the tank chamber is filled with cooling liquid, wherein the cover comprises a surface facing toward the piston;
an elastic element connected with the housing and the piston, and the elastic element is free from contact with the cooling liquid; and
an outlet pipe communicating with the tank chamber, wherein an extension direction of an opening of the outlet pipe is not parallel to a direction of movement of the elastic element, a distance between the outlet pipe and the surface of the cover is less than a length of the support post;
wherein when the cooling liquid is decreased, the piston compressed the tank chamber such that the elastic element is released, and the tank chamber is continuously compressed by pairing the elastic element and the piston.
