Water pillow for heat radiation

Abstract

According to a water pillow for heat radiation for touching a heat generating object, absorbing heat from the heat generating object and radiating heat by cooling liquid that circulates inside the water pillow, said device includes an inflow inlet for flowing the cooling liquid inside the water pillow, a drain outlet for flowing the cooling liquid out of inside the water pillow, a plurality of cooling fins spoke wise disposed on a first plane constituting a cavity inside the water pillow where the cooling liquid circulates and an impeller for circulating in a whirl the cooling liquid disposed on a second plane opposed in parallel or almost parallel with the first plane.

1 . A water pillow for heat radiation for touching a heat generating object, absorbing heat from the heat generating object and radiating heat by cooling liquid that circulates inside the water pillow, comprising:
 an inflow inlet for flowing the cooling liquid inside the water pillow;   a drain outlet for flowing the cooling liquid out of inside the water pillow;   a plurality of cooling fins spokewise disposed on a first plane constituting a cavity inside the water pillow where the cooling liquid circulates; and   an impeller for circulating in a whirl the cooling liquid disposed on a second plane opposed in parallel or almost parallel with the first plane.   
   
   
       2 . The water pillow for heat radiation according to  claim 1 , wherein
 each of said cooling fins spokewise disposed on the first plane forms a circular arc or almost circular arc forming a curved line in a circulating direction of the cooling liquid that circulates in a whirl inside the water pillow.   
   
   
       3 . The water pillow for heat radiation according to  claim 1 , wherein
 each of said cooling fins spokewise disposed on the first plane forms an elevation angle which is formed between the first plane and the cooling fin and which is formed on a side where the cooling liquid that circulates in a whirl inside the water pillow is directly applied.   
   
   
       4 . The water pillow for heat radiation according to  claim 1 , wherein
 each of said cooling fins spokewise disposed on the first plane has a cross-section cut along a plane orthogonal to the cooling fin and the first plane which shows a form of concave circular arc or almost circular arc on a side where the cooling liquid that circulates in a whirl inside the water pillow is directly applied.   
   
   
       5 . The water pillow for heat radiation according to  claim 4 , wherein
 said cooling fin forms a larger circular arc or almost circular arc or plane in a farther outer circumference side of the radiation.   
   
   
       6 . The water pillow for heat radiation according to  claim 4 , wherein
 height of said cooling fin from the first plane increases in a farther outer circumference side of the radiation.   
   
   
       7 . The water pillow for heat radiation according to  claim 1 , wherein
 said cooling fins are a group of sets of a plurality of cooling fins having different height.   
   
   
       8 . The water pillow for heat radiation according to  claim 7 , wherein
 said cooling fins are disposed in such a way that the height of the cooling fins gradually increases along a circulating direction of the cooling liquid that circulates in a whirl inside the water pillow.   
   
   
       9 . A cooling device provided with a water pillow for heat radiation for touching a heat generating object, absorbing heat from the heat generating object and radiating heat by cooling liquid that circulates inside the water pillow, said device comprising:
 a water pillow comprising:
 an inflow inlet for flowing the cooling liquid inside the water pillow; 
 a drain outlet for flowing the cooling liquid out of inside the water pillow; and 
 a cavity which is inside the water pillow that circulates the cooling liquid and which includes a plurality of cooling fins spokewise disposed on a first plane constituting the cavity and an impeller disposed on a second plane opposed in parallel or almost parallel with the first plane for circulating the cooling liquid in a whirl, and 
   a pump for flowing the cooling liquid in the flow inlet, flowing the cooling liquid out of the drain outlet and circulating the cooling liquid in the cavity.
