Title:
HEAT PIPE, HEAT EXCHANGER, AND METHOD FOR MANUFACTURING HEAT PIPE
Document Type and Number:
Japanese Patent JP2023152616
Kind Code:
A
Abstract:
To provide a heat pipe improved in heat exchange efficiency, and to provide a method for manufacturing the same.SOLUTION: In a heat receiving chamber 120 and a heat radiation chamber 140 of a heat pipe 100, a width in a second direction is longer than a width in a second direction of a connection pipe 101 when viewed from a first direction. A plurality of wicks 105 are formed in a line at least in the second direction, and the wicks 105 have a groove shape formed in the heat receiving chamber 120, the heat radiation chamber 140 and an inner wall surface of the connection pipe 101. At least the one wick 105 has a heat receiving chamber side bent part and a heat radiation chamber side bent part 142 bent in the second direction in the heat receiving chamber 120 and the heat radiation chamber 140 when viewed in the first direction. In the wicks 105 adjacent in the second direction, an interval in the heat receiving chamber 120 and an interval in the heat radiation chamber 140 are wider than an interval in the connection pipe 101. The heat receiving chamber 120, the heat radiation chamber 140, the connection pipe 101 and the wicks 105 are integrally molded by laminate molding metal powder.SELECTED DRAWING: Figure 3
