Abstract:
A heat exchanger for cooling electronic or electrical components, comprising:a first cup-like component having a bottom and a peripheral wall about the bottom; a second cup-like component having a bottom and a peripheral wall about the bottom, said second component being nested within said first component with their bottoms and peripheral walls spaced from one another to define a flow channel therebetween; a circuit board mounting components to be cooled mounted on said first component bottom in heat conducting relation thereto and on a side thereof opposite said second component bottom; an inlet to said flow channel; an outlet from said flow channel; and a cover extending about said second component and sealed to said second component peripheral wall in spaced relation to said second component bottom to define a fluid receiving space, said fluid receiving space being in fluid communication with said flow channel; whereby said components to be cooled may be cooled either by fluid circulating in said flow channel by pumping or by fluid in said fluid receiving space.
