Heat radiator

Abstract

A heat radiator includes a heat absorbing element, a heat radiating element, and a pump connected with the heat absorbing element and the heat radiating element to define a closed circuit. The pump circulates a refrigerant through the closed circuit. The heat absorbing element includes a heat-exchanging portion for transferring heat generated by a heating element to the refrigerant, a cover joined to a peripheral edge of the heat-exchanging portion to define a refrigerant flow channel therebetween, and one or more connecting members disposed within the refrigerant flow channel and having opposite ends joined to the heat-exchanging portion and the cover, respectively, to connect the heat-exchanging portion and the cover with each other.

1 . A heat radiator comprising: 
 a heat absorbing element;    a heat radiating element;    a pump connected with said heat absorbing element and said heat radiating element to define a closed circuit, said pump circulating a refrigerant through the closed circuit; and    said heat absorbing element comprising: 
 a heat-exchanging portion adapted to transfer heat generated by a heating element to the refrigerant;  
 a cover joined to a peripheral edge of said heat-exchanging portion to define a refrigerant flow channel therebetween; and  
 at least one connecting member disposed within the refrigerant flow channel and having opposite ends joined to said heat-exchanging portion and said cover, respectively, to connect said heat-exchanging portion and said cover with each other.
