Abstract

The invention provides a heat exchange tube, a manufacturing method of the heat exchange tube and a heat exchanger with the heat exchange tube. Arc-shaped grooves perpendicular to the length direction of the heat exchange tube are formed in the surface of the heat exchange tube, the arc-shaped grooves are distributed in a discontinuously staggered mode in the circumferential direction of the heat exchange tube, and the arc-shaped grooves are evenly distributed in the length direction of the heat exchange tube. The surface of the heat exchange tube is designed to be of the structure that the arc-shaped grooves are formed in the discontinuously staggered mode, and the heat exchange area of the heat exchange tube can be effectively increased through the structure. Meanwhile, through the structure that the arc-shaped grooves are formed in the discontinuously staggered mode, gas can generate turbulent flow with strong impacts between clearances of the discontinuously staggered arc-shaped grooves, the impact force of the turbulent flow to the inner wall of the heat exchange tube is enhanced, accumulation of carbon in the gas is effectively reduced, and generation of the accumulated carbon is controlled.

Description

technical field

[0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange tube, a manufacturing method thereof and a heat exchanger equipped with the heat exchange tube. Background technique

[0002] The heat exchange tube is the core component of the heat exchanger, and the structural design of the heat exchange tube has a great influence on the heat exchange efficiency of the heat exchanger. At present, the heat exchange tubes sold in the market mainly include circular tubes with a smooth tube structure and circular tubes with a spiral structure. The circular tubes with a bare tube structure have poor heat exchange efficiency due to the fast passage of hot gas and the short contact time with the refrigerant. Due to the existence of the helical structure, the hot gas generates turbulent flow when passing through the heat exchange tube, which increases the residence time of the hot gas in the heat exchange tube and improves the he...
