Ebullient cooling device

Abstract

An ebullient cooling device that can maintain favorable cooling-medium circulation is provided. An ebullient cooling device according to the present invention is characterized in that it is an ebullient cooling device that includes a heat receiving unit to which a heating element is installed, and which has a cooling medium in the inside, a condensing unit which communicates with the heat receiving unit, and which condenses the cooling medium that has been boiled by means of heat resulting from the heating element, a cooling-medium circulating unit which communicates with the heat receiving unit and condensing unit, into which the cooling medium having been condensed at the condensing unit flows and additionally which supplies the cooling medium to the heat receiving unit, and an inner bottom face of the condensing unit includes a guiding portion which guides the cooling medium to the cooling-medium circulating unit by means of gravity.

1 . An ebullient cooling device being characterized in that it is an ebullient cooling device comprising:
 a heat receiving unit to which a heating element is installed, and inside of which a cooling medium is accommodated;   a condensing unit which lies successively to said heat receiving unit, and inside of which a heat exchanger is accommodated, the heat exchanger being for condensing said cooling medium that has been boiled by means of heat resulting from said heating element;   a cooling-medium circulating unit which lies successively to said heat receiving unit and to said condensing unit, and which returns said cooling medium having been condensed at said condensing unit back to said heat receiving unit; and   an inner bottom face of said condensing unit comprising a guiding portion which inclines downward, and which guides said cooling medium having been condensed at said heat exchanger to said cooling-medium circulating unit.   
     
     
         2 . The ebullient cooling device as set forth in  claim 1 , wherein said guiding portion is an inclining face that inclines so as to be headed downward as it goes toward said cooling-medium circulating unit. 
     
     
         3 . The ebullient cooling device as set forth in  claim 1 , wherein said condensing unit has an inner bottom face whose entire face is said guiding portion. 
     
     
         4 . The ebullient cooling device as set forth in  claim 1 , wherein said heat exchanger is disposed above the inner bottom face of said condensing unit and above said cooling-medium circulating unit. 
     
     
         5 . The ebullient cooling device as set forth in  claim 1 , wherein said heat receiving unit has a deflector plate which not only marks off between the heat receiving unit per se and said cooling-medium circulating unit but also deflects said cooling medium having been boiled toward said heat exchanger.
