PURPOSE:To contrive a miniaturization of the titled device by a method wherein a chemical heat pump that applies organic chemistry catalytic reaction is arranged midway in a cooling system and the temperature difference between a secondary cooler and the air is made larger. CONSTITUTION:A semiconductor element 1 for power having cooling fins 2 is dipped in such liquid-phase coolant 4 as isopropanol stored in a liquid-phase heat-absorbing reactor 3. This reactor 3 is provided with a first cooler 5, wherein part of evaporated gas is condensed by cooling air (a), on its upper part. A chemical heat pump system is formed with the reactor 3 and a vapor-phase heat-generating reactor 7, wherein a change of the state of vapor-phase coolant 9 is caused, is provided. Moreover, a second cooler 8, which is used for absorbing the heat of gas by cooling air (b), is provided on the upper part of the reactor 7 as well. Furthermore, a heat exchanger 6, by which gas come out of the first cooler 5 is heated with heat inertia and fed in the second cooler 8 and gas come out of the reactor 7 is cooled and returned to the reactor 3, is provided between the reactors 3 and 7. This heat exchanger 6 is heat-insulated from the surroundings and executes the transfer of heat between gases to pass in the mutually opposing directions. |
