<p>PROBLEM TO BE SOLVED: To increase the contact area between a condenser and a radiation body and to ensure the effective radiation by placing the condenser to cover the radiation body. SOLUTION: A cylindrical evaporator 1 is fixed at a display part 20 and its center axis line is set on the same line as a center axis line 35 of an engagement axis 34 set between the part 20 and a main body 23. One of both ends of a heat conduction member 36 covers around the evaporator 1 and also has a round pipe shape to be relatively revolved in the circumferential direction of the evaporator 1. The other end of the member 36 touches the surface of a heating body 24 and transmits the heat. A condenser has two passages 9a to flow the operating fluids, and every passage 9a covers a radiation shield 22 and uses a loop-shaped heat pipe having a smooth inner wall. Thus, the passage 9a can increase the bending frequency and accordingly increases the contact area to the shield 22.</p> |
