ウトを起こすおそれがある。Problems to be Solved by the Invention For example, heat pipes used in audio equipment, etc. are often forced to be installed almost horizontally due to space constraints. There is a problem that it becomes difficult to flow to the side, resulting in a decrease in heat transfer performance. Furthermore, if the gaseous working fluid generated in the evaporator becomes difficult to flow toward the condensing section, the pressure of the gaseous working fluid may cause the working fluid to move toward the condensing section, potentially causing dryout.
この発明の目的は、上記問題を解決したヒートパイプを
提供することにある。An object of the present invention is to provide a heat pipe that solves the above problems.

。Means for Solving the Problems A heat pipe according to the present invention is a heat pipe that has a horizontal straight tubular container and a working fluid sealed in the container, and has an upwardly protruding chamber in a predetermined length portion at the right end of the container. A partition wall is provided in the container, which partitions the inside of the container into an upper and lower part, and has a gaseous working fluid passage section at the left end and a reliquefied working fluid passage section at the right end. The liquid is sealed in a portion of the container below the partition wall.

くなり、放熱量が多くなる。Function: Since the heat pipe according to the present invention is configured as described above, the gaseous working fluid generated in the evaporation section passes through the gaseous working fluid passing section formed at the left end of the partition wall and flows through the partition wall. It enters the upper part, flows through it to the right, and further enters the upward projecting chamber, where the heat of the gaseous working fluid is radiated to the outside through the peripheral wall of the container and reliquefied. Then, the reliquefied hydraulic fluid passes through the reliquefied hydraulic fluid passage section, enters the lower part of the partition wall, passes therethrough, and flows to the left side.
Return to the evaporation section. Therefore, the hydraulic fluid circulates smoothly within the container. Furthermore, since the gaseous working fluid is configured to condense in the upwardly projecting chamber of the container, the heat radiation area is larger and the amount of heat radiation is increased compared to a heat pipe having a straight container.
