Abstract
A loop heat pipe includes: an evaporator; a condenser; a liquid pipe; a vapor pipe; and a loop-like flow channel through which the working fluid flows. At least one of the evaporator, the condenser, the liquid pipe, and the vapor pipe includes a first outer metal layer, a second outer metal layer, and an inner metal layer. The inner metal layer includes a porous body. The porous body includes: a first bottomed hole formed in one face of the inner metal layer; a second bottomed hole formed in the other face of the inner metal layer; a pore, wherein the first bottomed hole and the second bottomed hole partially communicates with each other through the pore; and a first column portion provided inside the first bottomed hole. The first column portion is bonded to the first outer metal layer.

A loop heat pipe comprising:
- an evaporator that vaporizes a working fluid;
- a condenser that condenses the working fluid;
- a liquid pipe that connects the evaporator and the condenser to each other;
- a vapor pipe that connects the evaporator and the condenser to each other;
- and
- a loop-like flow channel that is provided in each of the evaporator, the condenser, the liquid pipe, and the vapor pipe, and through which the working fluid flows,
- wherein
- at least one of the evaporator, the condenser, the liquid pipe, and the vapor pipe comprises a first outer metal layer, a second outer metal layer, and an inner metal layer that is provided between the first outer metal layer and the second outer metal layer,
- the inner metal layer comprises a porous body,
- the porous body comprises:
- a first bottomed hole formed in one face of the inner metal layer;
- a second bottomed hole formed in the other face of the inner metal layer;
- a pore, wherein the first bottomed hole and the second bottomed hole partially communicates with each other through the pore;
- and
- a first column portion provided inside the first bottomed hole, wherein the first column portion is bonded to the first outer metal layer, and the first column portion is provided apart from an inner wall of the first bottomed hole.
