JPH116694A - Polybutene heat pipe - Google Patents

Abstract

PROBLEM TO BE SOLVED: To melt the snow by radiating the heat from a polybutene heat pipe. SOLUTION: A working fluid 2 such as water or chlorofluorocarbon-replacing material fills a polybutene heat pipe 1. The pipe 1 is evacuated or made vacuum after the working fluid is cast, and fused to be sealed. One side of the polybutene heat pipe 1 is connected to a main pipe 3, and the thermal medium such as hot water or antifreezing fluid circulates therein to heat the polybutene heat pipe 1. The thermal medium is heated in a boiler 5, and circulated in the main pipe 3 by a pump 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to melting snow with a polybutene heat pipe sealed by fusion.

[0002]

2. Description of the Related Art Conventionally, the material of a heat pipe is a metal pipe such as stainless steel, copper or steel pipe. In addition, the ends were welded or silver brazed to seal.

[0003]

However, in such a method, first, since it is a metal pipe and thus has no flexibility, it is necessary to cast a concrete on a roadbed to obtain a level. there were. In addition, the length of transport for straight pipes is limited, and products longer than 6 meters in general cannot be transported. Furthermore, when lengthening at the site, work such as welding is required, and there is a problem in construction management.

[0004]

The present invention has the following arrangement to solve the above-mentioned problems. Cut the polybutene pipe wound into a coil to the required length, put the working fluid in it, depressurize or evacuate, then fuse and seal to form a heat pipe And

[0005]

Next, the operation will be described. The heat is radiated and melted by the polybutene heat pipe.

[0006]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Reference numeral 1 denotes a polybutene heat pipe into which a working fluid 2 is filled. Further, one side of the polybutene heat pipe is connected to the main pipe 3, in which a heat medium 4 such as warm water or antifreeze circulates, and heats the polybutene heat pipe. The heating medium 4 is heated by a boiler 5 and circulated through a main pipe 3 by a pump 6.
As described above, various preferred embodiments of the present invention have been described, but the present invention is not limited to these embodiments.
Of course, many modifications can be made without departing from the spirit of the invention.

[0007]

As is clear from the above, according to the present invention, the following remarkable functions and effects are exhibited. B) Because it has flexibility, the roadbed only needs to be compacted.
Construction time can be shortened. B) Lightweight for a polybuden pipe, coiled,
Can be transported compactly.
゜ c) Since the seal can be easily made by fusion, construction on site is easy. D) It can be manufactured in a length that allows heat transfer.
