<P>PROBLEM TO BE SOLVED: To improve heat exhausting efficiency and to dispense with welding connection of heat transfer tubes in a radiation type heat exhauster including the heat transfer tubes inside thereof. <P>SOLUTION: This radiation type heat exhauster includes a core tube base 1, a plurality of heat exhaust fins 2, and the U-type heat transfer tube 3, and the plurality of heat exhaust fins 2 are connected to an outer peripheral wall of the core tube base 1. The U-type heat transfer tube 3 is buried in and connected to a hollow inner wall or/and a bottom section of the core tube base 1. The U-type heat transfer tubes 3 is disposed in a state of being press-fitted in mounting grooves 11 formed on the hollow inner wall or/and the bottom section of the core tube base 1 in advance. A bottom section of the U-type heat transfer tube 3 is exposed so that it can be directly kept into contact with a heat source. Thus, the heat exhausting efficiency of the heat exhauster can be improved. Further, as the U-type heat transfer tube 3 is tightly connected to the core tube base 1, welding connection is unnecessary. <P>COPYRIGHT: (C)2012,JPO&INPIT |
