Cooling device for heat-generating elements

摘要

A cooling device for cooling heat generating elements in which a cooling effect is produced by collision of a coolant with the back face side of heat-generating elements ( 1 ). The coolant ( 10 ) is introduced into a coolant introduction chamber ( 3 ) within a first coolant contact chamber ( 4 ) and is then introduced into the first coolant contact chamber ( 4 ) by injection from a central nozzle ( 7 ). Thereafter the coolant ( 10 ) produces a cooling effect in a second coolant contact chamber ( 5 ) and in a third coolant contact chamber ( 6 ). Since peripheral nozzles ( 8 ) and ( 9 ) are formed so as to spread in radial fashion about central nozzle ( 7 ), uniform cooling of the back face side of the heating-generating elements ( 1 ) is observed. As a result, there is no possibility of large tensile heat stress being generated at the heat-generating elements ( 1 ).
