Abstract

PURPOSE:To form a micro heat pipe having a wick structure, which allows to be turned into a structure more smaller in diameter, by a structure wherein a plurality of wicks are arranged so as to be inscribed with or positioned with minute gap to the inner wall surface of a small diameter cylindrical vessel with both ends closed and working liquid is sealed within said vessel. CONSTITUTION:Two wicks, which extend in the direction of the axis of a vessel 1 and contact with each other, are inserted in the cylindrical heat pipe vessel 1 so as to contact with the inner surface of the vessel 1. In addition, working liquid 3 is sealed within the vessel 1. Accordingly, the working liquid 3 is held in narrow gaps formed between the inner surface of a cylinder and the outer surfaces of the wicks 2. The working liquid 3 condensed at a condenser section returns an evaporator section by means of said gaps, while evaporated working liquid flows through spaces within the vassel 1. Further, the employment of three wicks is also effective similarly. The heat pipe consists of very simple component parts, which allow to be turned into parts more smaller in diameter and also are assembled easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a polar RJJW heat vibrator, a so-called micro heat pipe.

[Technical background of the invention and its problems]

Applications of the ultra-fine round heat vibrator are being considered, such as cooling ICs. However, with the conventional quick structure such as the group 4 provided on the inner surface of the container 1 shown in FIG. 3, wire mesh, and thin wire bundle,
Due to manufacturing and assembly issues, there was a limit to the diameter reduction (=), and it was difficult to realize a heat vibrator of less than one cabinet.In addition to the above constraint conditions, with conventional thin wire bundle manufacturing, the steam M inside the heat vibrator
It was difficult to secure a flow path for 'i.

[Purpose of the invention]

This invention improves the drawbacks of the conventional heat vibrator described above, and aims to provide a micro heat pipe having a wick structure that allows the diameter to be reduced.

[Summary of the invention]

This invention is characterized by the fact that the core wires of the double wheels are arranged in a cylindrical container (2) in contact with each other (2), and also in contact with the ml inside the container, or with a slight gap, so that the outer diameter of the core wire This is a micro heat pipe that uses the gap formed by the inner surface of the circular tube as a wick.

〔Effect of the invention〕

It has a very simple structure in which multiple single core wires are inserted into a circular tube, and it is easy to process, and the circular tube and core wires themselves are very thin. It is easy to make the diameter smaller.

[Embodiments of the invention]

A cross-sectional view of one embodiment of the present invention is shown in FIG. The inner surface of the heat pipe container 1, which is a circular tube, is inserted so that the two core wires are in contact with each other in the axial direction of the container. Because of this structure, there is a narrow gap formed between the inner surface of the circular tube and the outer surface of the core wire. , the evaporated working fluid flows in the space inside the container 1.Also, the same effect can be obtained with three pipes as shown in FIG.

Comparing this with Group Quick's conventional heat pipe as shown in Figure 3, the heat pipe of the present invention is composed of very simple components that can be made smaller in diameter, and is easy to assemble. , an ultra-thin heat pipe (with two suitable structures can be said to be β).

Note that when core wires of equal diameter are inscribed in the container, the circulation space for the evaporative working fluid can be secured at 50 inches of the container's internal cross section with two core wires, and approximately 35 inches with three core wires, and sufficient cooling efficiency can be obtained.
