Problems solved by technology

[0003] The cross-section of the heat exchange tube in a conventional shell-and-tube heat exchanger is generally a circular tube with the same inner and outer diameters. The heat exchange area of ​​such pipelines and cooling medium flow is small, the heat exchange efficiency is relatively low, and the overall weight of the heat exchanger is relatively large.

Embodiment Construction

[0010] exist figure 1 Among them, several heat pipes (1) pass through the heat exchanger shell (3), and the outer wall of the heat pipe is bored with a spiral ring with a width of 1 / 4 pipe diameter and a depth of 1 / 2 wall thickness. The projection angle of the annular groove and the axial direction is 45°. The heat pipe is connected to the shell of the heat exchanger with a support plate.

Abstract

The invention discloses a novel heat exchange tube of a heat exchanger, which can be used for improving heat exchange efficiency by boring a spiral rectangular groove on the outer wall of the heat exchange tube.

Description

Technical field [0001] The purpose of the present invention is a novel heat exchange tube in a shell-and-tube heat exchanger with higher heat exchange efficiency. Background technique [0002] Shell and tube heat exchangers are widely used in the process industry. Conventional tube heat exchangers are usually composed of circular tubes, where one medium flows inside the tube and the other medium flows outside the tube. Due to this structure, tube heat exchangers are suitable for applications requiring high temperature and pressure. The most common types of tube heat exchangers include double tube heat exchangers and shell and tube heat exchangers. [0003] The cross-section of the heat exchange tube in a conventional shell and tube heat exchanger is generally a circular tube with the same inner and outer diameters. The heat exchange area of ​​such pipelines and cooling medium flow is small, the heat exchange efficiency is relatively low, and the overall weight of the heat e...
