An anti-corrosion finned tube

Abstract

The invention provides a finned tube. The finned tube comprises a base tube and transverse fins arranged on the base tube, wherein the base tube and the fins are coated with anticorrosive layers. According to the finned tube, by arranging the anticorrosive layers, the finned tube can be prevented from being corroded in the heat exchange process, and the heat exchange effect can be further improved.

Description

technical field [0001] The invention belongs to the field of heat exchangers, and in particular relates to a heat exchanger component-finned tube. Background technique [0002] With the rapid development of modern society and economy, human beings have an increasing demand for energy. However, the reserves of traditional energy sources such as coal, oil, and natural gas are constantly decreasing and becoming increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious, which greatly limits the development of society and the improvement of human life quality. . Therefore, in order to save energy, heat transfer enhancement technology is constantly developing, and finned tubes are also widely used in the field of heat transfer. At present, the fins in the prior art are integrally arranged on the base tube. Therefore, although the finned tube has the function of enhanci...

AI Technical Summary

Problems solved by technology

At present, the fins in the prior art are all arranged on the base tube as a whole. Therefore, although the use of finned tubes has the function of enhancing heat transfer, under certain working conditions, such as flue gas heat exchange and impurities In terms of gas heat exchange, ash collection may occur, resulting in a decrease in heat transfer coefficient. Therefore, the present invention proposes a new heat exchange tube for the current situation in the prior art.
