COOLING JACKET, AND COOLING SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide means of maintaining thermal conductivity to prevent reduction in cooling efficiency even in the case where failures occur in one cooling flow channel.SOLUTION: In a cooling jacket, a plate-like heat exchange plate 30 for heat exchange between a first cooling medium flowing in a plurality of long slits 30a opened so as to be contacted with a plate-like heat reception plate 40 receiving heat from a heating element and to extend in a plate-surface direction and a second cooling medium flowing in a plurality of slits 30b opened so as to be contacted with the heating element and to extend in the plate-surface direction, and first and second cooling flow channels for circulating these first and second cooling mediums individually in the slits 30a and the slits 30b of the heat exchange plate 30, are formed by a relay plate 20 and flow dividing tubes 10 to 13.
