Description

【発明の詳細な説明】 本発明は熱交換効率と組立作業性を向上せしめた筒型熱
交換器に関するものである。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cylindrical heat exchanger with improved heat exchange efficiency and ease of assembly.

放熱部とし、下部を高温ガスが流通する吸熱部としたも
のがある。
Conventionally, a cylindrical heat exchanger has a hollow cylindrical body with a spiral peripheral wall surface and an open end surface of the vortex, and an annular partition plate is provided horizontally inside the peripheral wall surface, and ducts are formed above and below. Inside the formed casing, a cylindrical heat exchange section is installed in which multiple heat pipes are inserted in an annular manner in the vertical direction of a circular partition plate, and the upper part of the cylindrical heat exchange section is used for heat dissipation through which the low-temperature gas to be heated flows. The lower part is an endothermic part through which high-temperature gas flows.

However, in the heat exchanger having the above structure, the heat pipes are arranged concentrically, radially, spirally, etc. on a circular partition plate, and the distance between the heat pipes is not constant, resulting in non-uniform gas flow.

また上記筒型の熱交換部は渦巻型のケーシング内に装着

た。
In addition, since the cylindrical heat exchanger mentioned above is installed inside a spiral casing, the part of the heat exchanger located at the back of the vortex is affected by turbulent flow resistance and wall resistance inside the duct. As a result, gas is not sufficiently supplied to the part located deep in the vortex on the heat radiation part side, and gas is not sufficiently exhausted from the heat absorption part side, resulting in a biased flow of gas as a whole. The disadvantage was that the flow was uneven and the heat exchange efficiency was low.

In view of the above, the present invention has a cylindrical heat exchange section in which a plurality of heat pipes are inserted annularly through a partition plate, and is mounted inside a spiral casing, with the upper part being a heat radiating part and the lower part being a heat absorbing part. In the cylindrical heat exchanger, a plurality of partition walls are provided radially on both upper and lower surfaces of the peripheral part of the partition plate constituting the heat exchange part, respectively perpendicularly thereto, to divide the heat exchange part into a plurality of blocks. We have developed a cylindrical heat exchanger that prevents gas drift and improves heat exchange efficiency.
