Abstract
A water block is used to be adhered to a heat-generating element and includes a cavity. The cavity has a chamber therein. One side or both sides of the chamber is provided with an inlet pipeline and an outlet pipeline respectively, thereby communicating with the chamber. Further, the chamber is provided therein with a heat-exchanging means for performing a heat-exchanging action with a working fluid. Finally, the top face of the cavity is provided with a membrane. An activating element is adhered on the membrane for driving the membrane to swing up and down, thereby forcing the working fluid within the chamber to circulate in single direction. The activating element is used as a power source, and in addition, the water block can be made much thinner.
