Liquid cooling device

Abstract

A liquid cooling device has a main liquid block, a pump, a heat sink, and at least one auxiliary liquid block that are in fluid communications. The auxiliary liquid block has a body and a partition that separates the body into a reservoir and a heat-absorbing chamber. The reservoir and the heat-absorbing chamber communicate with and other via a through hole on the partition. Since the heat-absorbing chamber is mounted to be adjacent to an electronic component that generates heat, the fluid in the heat-absorbing chamber absorbs the heat. When the fluid in the heat-absorbing chamber vaporizes and decreases the fluid in the reservoir has a higher level and thus flows to the heat-absorbing chamber via the through hole. Therefore, the heat-dissipating ability of the liquid cooling device is increased.

1 . A liquid cooling device comprising:
 a main liquid block being filled with a coolant;   a pump being mounted on the main liquid block and in fluid communications with the main liquid block;   a heat sink connected with the pump via a tubing;   at least one auxiliary liquid block filled with a coolant, each of the at least one auxiliary liquid block comprising:
 a body having a side surface for contacting an electronic component that generates heat; 
 a partition formed in the body and separating the body into a reservoir and a heat-absorbing chamber being adjacent to the side surface of the body; 
 at least one through hole formed on the partition to communicate the reservoir and the heat-absorbing chamber; 
 a fluid inlet and a fluid outlet being respectively in fluid communications with the reservoir and the heat-absorbing chamber and connected via tubing with the main liquid block and the heat sink. 
   
   
   
       2 . The liquid cooling device as claimed in  claim 1 , the at least one auxiliary liquid block comprising:
 a first auxiliary liquid block having a fluid inlet and a fluid outlet fluid being in fluid communications with the heat sink via the tubing; and   a second auxiliary liquid block having a fluid inlet and a fluid outlet are in fluid communications with the fluid inlet and the fluid outlet of the first auxiliary liquid block and in fluid communications with the main liquid block via tubing.   
   
   
       3 . The liquid cooling device as claimed in  claim 1 , wherein the heat sink comprises:
 two containers being in fluid communications with the pump and the auxiliary liquid block respectively; and   a heat-dissipating assembly composed of multiple heat-dissipating blades and multiple fluid passages, each of the fluid passage communicating the two containers and each heat-dissipating blade being mounted between two adjacent fluid passage.   
   
   
       4 . The liquid cooling device as claimed in  claim 2 , wherein the heat sink comprises:
 two containers being in fluid communications with the pump and the auxiliary liquid block respectively; and   a heat-dissipating assembly composed of multiple heat-dissipating blades and multiple fluid passages, each of the fluid passage communicating the two containers and each heat-dissipating blade being mounted between two adjacent fluid passage.   
   
   
       5 . The liquid cooling device as claimed in  claim 1 , wherein the partition in the body of each auxiliary liquid block is formed with two through holes adjacent to an inner bottom surface of the body. 
   
   
       6 . The liquid cooling device as claimed in  claim 2 , wherein the partition in the body of each auxiliary liquid block is formed with two through holes adjacent to an inner bottom surface of the body. 
   
   
       7 . The liquid cooling device as claimed in  claim 3 , wherein the partition in the body of each auxiliary liquid block is formed with two through holes adjacent to an inner bottom surface of the body. 
   
   
       8 . The liquid cooling device as claimed in  claim 4 , wherein the partition in the body of each auxiliary liquid block is formed with two through holes adjacent to an inner bottom surface of the body.
