Abstract
A heat pipe includes an intermediate metal layer interposed between outermost metal layers, an inlet passage defined by opposing wall portions of the intermediate metal layer and the outermost metal layers, and a porous body provided at one or both of the wall portions. The porous body includes a first bottomed hole that caves in from one surface of the intermediate metal layer, a second bottomed hole that caves in from the other surface of the intermediate metal layer, and a pore formed by the first bottomed hole that partially communicates with the second bottomed hole. The outermost metal layers, the intermediate metal layer, the inlet passage, and the porous body form an inlet for filling a working fluid into the heat pipe.
Claims8
A heat pipe comprising:
- an inlet for filling a working fluid into the heat pipe, and including
- a first outermost metal layer;
- a second outermost metal layer;
- an intermediate metal layer interposed between the first and second outermost metal layers;
- an inlet passage defined by opposing wall portions of the intermediate metal layer, and the first and second outermost metal layers;
- and
- a porous body provided at one or both of the wall portions,
- wherein the porous body includes a first bottomed hole that caves in from one surface of the intermediate metal layer, a second bottomed hole that caves in from the other surface of the intermediate metal layer, and a pore formed by the first bottomed hole that partially communicates with the second bottomed hole.
A heat pipe comprising:
- an inlet for filling a working fluid into the heat pipe, and including
- a first outermost metal layer;
- a second outermost metal layer;
- a plurality of intermediate metal layers that are stacked and interposed between the first and second outermost metal layers;
- an inlet passage defined by opposing wall portions of the plurality of intermediate metal layers and the first and second outermost metal layers;
- and
- a porous body provided at one or both of the wall portions,
- wherein the porous body includes a first through-hole that penetrates a first intermediate metal layer among the plurality of intermediate metal layers, a second through-hole that penetrates a second intermediate layer among the plurality of intermediate metal layers and in contact with the first intermediate metal layer, and a pore formed by the first through-hole that partially communicates with the second through-hole.
