PROBLEM TO BE SOLVED: To heat air above a target object and prevent the surface of the target object from generating dew by a method wherein the target object to be cooled is placed on the upper surface of a cooling plate, an electronic cooling element is connected to the lower surface of the cooling plate, the thermal radiation fins are connected to the thermal radiation surface of the element and the thermal radiation part connected to the thermal radiation fins is positioned above the target object. SOLUTION: A cooling plate 5 on which upper surface is placed a case 15 for storing an object 17 to be cooled is cooled by a cooling surface of an electronic cooling element 1 connected to the lower surface of it. Thermal radiation fins 6 are connected to a thermal radiation surface of the electronic cooling element 1 and a thermal radiation section 14 of a heat transfer member 10 is connected to the thermal radiation fins 6. The thermal radiation section 14 is formed by a heat generating net and heat attained from the thermal radiation surface of the element 1 is transferred through a base plate 7 of the thermal radiation fins 6 and the lower part of the heat transfer member 10. In addition, the thermal radiation section 14 is positioned above the object 17 to heat air above the object 17. Due to this fact, a surface temperature of the object 17 contacted with the heated air is increased and its relative humidity is decreased, so that no dew is formed at the surface of the object. |
