TH142817A - Spiral fins increase the efficiency of louvered heat transfer. - Google Patents

Abstract

DC60 (11/06/57) spiral fin enhances rdaial louver spiral fin, following the invention of the development of a conventional spiral finned tube heat exchanger. With adding a groove The louvers on the fin surface have a special effect. Leads to increasing the heat transfer performance of air or Heat exchanger flow When compared with conventional helical flanges Make the device size Heat exchanger smaller Which is suitable for applications with limited space Can be used to create Heat exchanger By exchanging heat between fluids and fluids such as gases, liquids or dual-state fluids between gases and liquids. Or applied in exchange equipment Heat for heat recovery The spiral fin enhances the rdaial louver spiral fin heat transfer performance. Following this invention is the development of a conventional tubular louver heat exchanger. With adding a groove The louvers on the fin surface have a special effect. Leads to increasing the heat transfer performance with air or Heat exchanger flow When compared with conventional helical flanges Make the device size Heat exchanger smaller With applications where space is limited Can be used to create Heat exchanger By exchanging heat between fluids and fluids such as gases, liquids or dual-state fluids between gases and liquids. Or applied in exchange equipment Heat for heat recovery

Claims (1)

1. Helical fins increase the efficiency of heat transfer. A louver type, consisting of a pipe (1), is a cylindrical shape that serves to convey fluid Or working fluid to exchange heat With a distance of diameter The outer tube (b) the inner tube diameter (c) and the helical flanges (2) are sheeted. Enclosed, fixed along the entire length of the pipe (1) It serves to increase the heat transfer surface area of the pipes (1) to increase the heat transfer performance by tag:
