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 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 top surface of the water block is provided with a membrane. The membrane is provided thereon with an activating element, so that the membrane swings up and down at one side thereof to guide the flow of the 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.

1 . A water-cooling heat-dissipating system, comprising:
 a water block abutting against a heat-generating element for performing a heat conduction with the heat-generating element, the water block further including:
 a membrane provided on a top of the water block; and 
 an activating element adhered on an upper surface of the membrane, the activating element having a fixed end and a swinging end, the swinging end being movable along an arc-shaped trajectory at one side; 
   a plurality of conduits connected to the water block to facilitate flowing of working fluid; and   a heat exchanger penetrated by the conduit for performing a heat-exchanging action with the working fluid in the conduit.   
   
   
       2 . The water-cooling heat-dissipating system according to  claim 1 , further comprising:
 a second cavity being in fluid communication with the water block, an inner wall face of the second cavity being provided with a valve for blocking the working fluid from flowing back into the water block;   a third cavity being separated from the second cavity and in fluid communication with the water block, an inner wall face of the third cavity being provided with another valve for blocking the working fluid from flowing back into the water block.   
   
   
       3 . The water-cooling heat-dissipating system according to  claim 1 , wherein an interior of the water block is provided with a plurality of heat-dissipating pieces. 
   
   
       4 . The water-cooling heat-dissipating system according to  claim 1 , wherein the heat exchanger comprises a plurality of heat-dissipating pieces. 
   
   
       5 . The water-cooling heat-dissipating system according to  claim 1 , wherein the activating element is a piezoelectric piece. 
   
   
       6 . The water-cooling heat-dissipating system according to  claim 1 , further comprising a tank, the tank being in fluid communication with the water block via the conduit for storing the working fluid.
