Abstract

PURPOSE:To obtain a double pipe type heat exchanger whose heat exchange efficiency is high, by filling a space constituted with a space in an inner pipe, the inner pipe and an outer pipe with metallic foamed material. CONSTITUTION:A space A in an inner pipe 1 of a heat exchanger made of a double pipe consisting of the inner and outer pipes 1, 2 and a space B between the inner pipe 1 and the outer pipe 2 are filled densely with a metallic foamed material 3 (foamed metal) such as aluminum. As the foamed metal 3 is spongy and porous it possesses a large surface area. Then if, for example, room-temperature gas is streamed to the space A and high-temperature gas is streamed to the space B, effective heat exchange is possible through the foamed metal 3 and the inner pipe 1, and miniaturization of the heat exchanger itself becomes possible.

Description

【発明の詳細な説明】 発明の技術分野 本発明は熱交換器に係り、特に小型で熱効率の高い熱交
換器に関するものである。DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a heat exchanger, and particularly to a heat exchanger that is small and has high thermal efficiency.

器等の種々の型式の熱交換器が知られている。Technical Background A heat exchanger that brings two fluids (gas or liquid) of varying temperatures into contact through an all-solid wall and transfers heat between the two fluids is called a tube-in-tube type due to its structure. Various types of heat exchangers are known, such as double-tube heat exchangers, shell-and-tube heat exchangers, and stacked heat exchangers.

ばならないという欠点があった。Prior Art and Problems Among the heat exchangers mentioned above, in the double-tube heat exchanger, a fluid at or near room temperature is passed through the space between the inner tube and the outer tube forming the double tube. A fluid at a temperature lower or higher than the above-mentioned temperature is flowed into the space, and heat is exchanged through the wall of the inner tube. Conventionally, when such heat converters were used to cool devices such as computers, even if heat radiating fins were installed on the outside of the inner tube in an attempt to increase heat conversion efficiency, there was no significant effect, and the tube I needed to increase the length. Therefore, there was a drawback that the heat exchanger itself had to be made large.

発明の目的 上記欠点を鑑み本発明は効率の高い二重管式熱交換器を
提供すること全目的とする。OBJECTS OF THE INVENTION In view of the above drawbacks, it is an object of the present invention to provide a highly efficient double tube heat exchanger.
