HEAT TRANSFER DEVICE
First Claim
1. A heat transfer device comprising a heat pipe in which working fluid is enclosed, a heat receiving section being provided on one end side of the heat pipe and a heat radiating section being provided on another end side of the heat pipe, whereinon an inner wall of the heat pipe, a first wick having a relatively large capillary pressure is disposed in the heat receiving section of the heat pipe and a second wick having relatively small flow resistance is disposed in the heat radiating section of the heat pipe, a bent section bent between the heat receiving section and the heat radiating section is provided, a boundary section between the first wick and the second wick is disposed below the bent section in a gravity direction, and the heat receiving section is disposed above the bent section in the gravity direction.

Abstract
A heat transfer device includes a heat pipe in which working fluid is enclosed, a heat receiving plate provided on one end side of the heat pipe and a heat radiating fin provided on the other end side of the heat pipe, a first wick and a second wick that transfer working fluid provided on an inner wall surface of the heat pipe, a bent section bent between the one end side and the other end side, and a boundary section between the first wick and the second wick disposed in a lower part in the gravity direction of the bent section of the heat pipe or the heat transfer device. The heat transfer device can improve heat transfer characteristics with a simple configuration.
