Water-cooling heat-dissipating system

Abstract

A water-cooling heat-dissipating system for facilitating a heat-dissipating action with a heat-generating element includes a water block, a membrane pump, a water tank and a heat exchanger. The above-mentioned components are in fluid communication with one another via a plurality of conduits. The water block is attached on the heat-generating element to absorb the heat generated by the heat-generating element. The membrane pump generates a thrust to facilitate the working fluid to perform a cooling action. The water tank is used to store additional working fluid. The heat exchanger performs a heat-conducting action with the flowing working fluid, thereby dissipating the heat absorbed by the working fluid to the outside. In this way, the heat-generating element can be kept in a normal range of working temperature.
