<p><P>PROBLEM TO BE SOLVED: To provide a heat radiation device which is small in size, light in weight, and whose radiation quantity is large. <P>SOLUTION: Water which is generated at the reaction of hydrogen and oxygen at a fuel cell unit 5 is led from a drain pipe 6 and a conduit pipe 8 to a water-holding member 13 of a radiation 7, which is constituted at the upper part of a heating part 4. When the radiator 7 is heated by the heat from the heating part 4, the water soaked into the water-holding member 13 evaporates. At this evaporation time, a large amount of heat of vaporization is deprived of the radiator 7 to radiate the heating part 4. <P>COPYRIGHT: (C)2004,JPO</p> |
