Heat dissipating system having a heat dissipating cavity body

Abstract

A heat dissipating system includes a heat dissipating cavity body defining a receiving space and having a bottom wall adapted to contact a heat source, a working fluid disposed in the receiving space and adapted to absorb heat generated by the heat source, and a heat exchange unit for exchanging heat with the working fluid. The bottom wall is made of a thin metal plate, and is flexible to deform so that when the bottom wall is pressed against the heat source, the bottom wall conforms to and contacts tightly a contact surface of the heat source.

1 . A heat dissipating system, comprising:
 a heat dissipating cavity body defining a receiving space and having a bottom wall adapted to contact a heat source;   a working fluid disposed in said receiving space and adapted to absorb heat generated by the heat source; and   a heat exchange unit for exchanging heat with said working fluid;   wherein said bottom wall is made of a thin metal plate and is flexible to deform so that when said bottom wall is pressed against the heat source, said bottom wall conforms to and contacts tightly a contact surface of the heat source.   
   
   
       2 . The heat dissipating system of  claim 1 , wherein said bottom wall has a thickness of below 0.5 mm. 
   
   
       3 . The heat dissipating system of  claim 1 , wherein said bottom wall is convexed downwardly and toward the heat source. 
   
   
       4 . The heat dissipating system of  claim 1 , wherein said bottom wall is flat. 
   
   
       5 . The heat dissipating system of  claim 1 , wherein said heat dissipating cavity body further has a pleated surrounding wall connected to said bottom wall. 
   
   
       6 . The heat dissipating system of  claim 1 , wherein said heat dissipating cavity body further has a top wall, said heat exchange unit including a thermoelectric cooler that has a cold side in contact with said top wall, and a hot side opposite to said cold side, said working fluid being a condensable fluid movable upward toward said top wall when vaporized and movable downward toward said bottom wall when condensed. 
   
   
       7 . The heat dissipating system of  claim 6 , wherein said top wall has a non-planar inner surface. 
   
   
       8 . The heat dissipating system of  claim 7 , wherein said inner surface of said top wall is formed with a plurality of protrusions and depressions. 
   
   
       9 . The heat dissipating system of  claim 6 , wherein said heat exchange unit further includes a condenser, and a tubing unit in contact with said hot side of said thermoelectric cooler and connected fluidly to said condenser, said condenser and said tubing unit being non-communicated with said heat dissipating cavity body, said working fluid being further disposed in said condenser and said tubing unit. 
   
   
       10 . A heat dissipating cavity body adapted to contact a heat source, said heat dissipating cavity body comprising:
 top and bottom walls; and   a surrounding wall connected between said top and bottom walls to define a receiving space which is adapted to contain a working fluid;   wherein said bottom wall is made of a thin metal plate and is flexible to deform so that when said bottom wall is pressed against the heat source, said bottom wall conforms to and contacts tightly a contact surface of the heat source.   
   
   
       11 . The heat dissipating cavity body of  claim 10 , wherein said bottom wall has a thickness of below 0.5 mm. 
   
   
       12 . The heat dissipating cavity body of  claim 10 , wherein said bottom wall is convexed downwardly and toward the heat source. 
   
   
       13 . The heat dissipating cavity body of  claim 10 , wherein said bottom wall is flat. 
   
   
       14 . The heat dissipating cavity body of  claim 10 , wherein said surrounding wall is pleated. 
   
   
       15 . The heat dissipating cavity body of  claim 10 , wherein said top wall has a non-planar inner surface. 
   
   
       16 . The heat dissipating cavity body of  claim 15 , wherein said inner surface of said top wall is formed with a plurality of protrusions and depressions.
