Title:
バタフライ型フィンチューブ熱交換器
Document Type and Number:
Japanese Patent JP7236118
Kind Code:
B2
Abstract:
Disclosed is a heat exchanger with a butterfly finned pipe. The heat exchanger comprises a heat exchange pipe (1) and multiple groups of fins (2) arranged on the heat exchange pipe (1). Each group of fins (2) is in the form of a butterfly structure, wherein the butterfly structure is constituted by two half butterfly fins (2) symmetrically arranged at two sides of the heat exchange pipe (1), and four corners of each half butterfly fin (2) are all arc-shaped corners (3), with the radius of curvature of each arc-shaped corner (3) being from 10 mm to 100 mm. By means of the heat exchanger, acid etching, erosion-corrosion and stress corrosion to the heat exchanger, in particular to the heat exchange fins (2), are effectively reduced, and automatic dedusting is realized, improving heat transfer performance and prolonging the service life of the heat exchanger.
