Liquid cooling heat dissipating device with heat tubes gathering heat sources

Abstract

A liquid cooling heat dissipating device with heat tubes gathering heat sources includes a cold plate being disposed on the heat sources and a or a plurality of heat tubes disposed between the heat sources and the cold plate to contact with the heat sources completely, and an end of the respective heat tube is fixedly attached to the cold plate, respectively. The respective heat tube is sealed with a capillary material and a vapor-liquid working median contained inside. The respective heat tube contacts with the heat sources at different spots to gather the heat for being cooled with the cold plate simply.

1 . A liquid cooling heat dissipating device with heat tubes gathering heat sources comprising:
 a cold plate being disposed on said heat sources;   a or a plurality of heat tubes being disposed between said heat sources and said cold plate to contact with said heat sources completely, and having an end thereof to fixedly attached to said cold plate, respectively.   
   
   
       2 . The liquid cooling heat dissipating as defined in  claim 1 , wherein the bottom of the respective heat tube fixedly connected with a metal plate. 
   
   
       3 . The liquid cooling heat dissipating device as defined in  claim 1 , wherein the respective heat tube is sealed with a capillary material and a vapor-liquid working median being contained therein. 
   
   
       4 . The liquid cooling heat dissipating device as defined in  claim 3 , wherein said capillary material and the wall of the respective heat tube is made of copper, and the working median is water. 
   
   
       5 . The liquid cooling device as defined in  claim 1 , wherein the respective heat tube has an outer shape of “L”, “N” or “S”, and has a cross section of round, square or triangle. 
   
   
       6 . The liquid cooling heat dissipating device as defined in  claim 1 , wherein the respective heat tube is attached to said cold plate and said metal plate with welding, gluing or screw fastening. 
   
   
       7 . The liquid cooling heat dissipating device as defined in  claim 2 , wherein the respective heat tube is attached to said cold plate and said metal plate with welding, gluing or screw fastening.
