HEAT TRANSPORT DEVICE, FLOW PASSAGE MEMBER AND METHOD OF MANUFACTURING THE FLOW PASSAGE MEMBER

PROBLEM TO BE SOLVED: To provide an inexpensive heat transport device having good heat transport efficiency, a flow passage member and a method of manufacturing the flow passage member. SOLUTION: The flow passage member 4 provided in the heat transport device 100 is formed by weaving a plurality of second wires 9 into both ends of a plurality of first wires 8 extended along the longitudinal direction of the heat transport device 100. Both ends of the flow passage member 4 correspond to a heat absorbing part X' and a heat release part Y'of the heat transport device 100, respectively, and serve as phase change regions X, Y in which the phase of working fluid is changed. A portion sandwiched between the phase change regions X, Y serves as a movement region Z where the working fluid is moved. Since the movement region Z comprises the first wires 8 extended along the movement direction of the working fluid (direction shown by the arrow h), flow passage resistance during the movement of the working fluid is small in the movement region Z. Since the second wires 9 are not used in the movement region Z, this can reduce material cost. As a result, the inexpensive heat transport device 100 with good heat transport efficiency can be obtained. COPYRIGHT: (C)2011,JPO&INPIT
