Heat absorbing device

Abstract

A heat absorbing device includes a converter, a heat semi-conductor located on the converter, a cool guide plate placed on the heat semi-conductor, and a moisture-proof cap provided with a recessed accommodating space for receiving the heat converter and the heat semi-conductor. The moisture-proof cap has an upper opening that the cool guide plate is fitted closely in, and a combining mouth formed in its bottom for the combining member of the heat converter fitted closely therein, insulating the heat semi-conductor from exterior air.

1 . A heat absorbing device comprising:
 a heat converter provided with a main body, said main body having a heat absorbing member formed in an upper portion and a combining member formed around its circumference;   a heat semi-conductor provided with a cooling surface and a heat dissipating surface, said heat dissipating surface contacting said heat absorbing member of said heat converter;   a cool guide plate made of a material possible to evenly conducting heat and contacting said cooling surface of said heat semi-conductor; and   a moisture-proof cap made of a material conducing less heat and provided with a recessed accommodating space for receiving said heat converter and said heat semi-conductor therein, said moisture-proof cap further provided with an upper opening in said recessed accommodating space, said cool guide plate fitted sealingly in said upper opening, said moisture-proof can having a bottom formed with a combining mouth for said combining member of said heat converter fitted sealingly therein.   
   
   
       2 . The heat absorbing device as claimed in  claim 1 , wherein said cool guide plate has its circumference formed with an extended stepped projection, and said extended stepped projection pushes tightly just under an annular wall defining said upper opening of said moisture-proof cap. 
   
   
       3 . The heat absorbing device as claimed in  claim 1 , wherein a first sealing element is deposited between said extended stepped projection of said cool guide plate and said moisture-proof cap. 
   
   
       4 . The heat absorbing device as claimed in  claim 1 , wherein said first sealing element is a sealing rubber ring. 
   
   
       5 . The heat absorbing device as claimed in  claim 1 , wherein said combining mouth of said moisture-proof cap is provided with an extended annular edge, which overlaps sealingly to said combining member of said heat converter. 
   
   
       6 . The heat absorbing device as claimed in  claim 5 , wherein a second sealing element is deposited between said combining member of said heat converter and said annular edge of said moisture-proof cap. 
   
   
       7 . The heat absorbing device as claimed in  claim 6 , wherein said second sealing element is a rubber. 
   
   
       8 . The heat absorbing device as claimed in  claim 1 , wherein said moisture-proof cap is provided with threaded holes of a preset number, and said heat converter is provided with combining holes of the same number as that of said threaded holes of said moisture-proof cap, and said combining holes are aligned with said threaded holes for bolts to fasten them respectively.
