Abstract
A cooling structure for heat generating electronic components mounted on a substrate. The cooling structure includes a cold plate fixed on the substrate which is provided with first through holes opposed to the respective upper surfaces of the heat generating electronic components, flow paths formed within the cold plate for circulating a coolant, an inlet provided on a side of the cold plate for supplying the coolant into the flow paths, an outlet provided on a side of the cold plate for exhausting the coolant from the flow paths, and pistons inserted through and held within the first through holes so that the lower surfaces of the pistons come into contact with the upper surfaces of the heat generating electronic components.
