Problems solved by technology
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 corrugated pipes (1) pass through the heat exchanger shell (3) and are fixed in the shell by each support plate (4). The cylindrical section of the bellows is connected to the support plates, while the corrugated section (5) is located between the support plates. One medium enters the heat exchange tubes, and the other medium flows in the space between the shell and the heat exchange tubes. The two media pass through the bellows for heat exchange.

The invention discloses a heat exchange tube of a novel heat exchanger. A corrugated tube is used as the heat exchange to increase heat exchange area and improve heat exchange efficiency.
Description
Technical field [0001] The purpose of the present invention is a novel shell-and-tube heat exchanger which adopts bellows as heat exchange tubes to improve heat exchange efficiency. Background technique [0002] Shell and tube heat exchangers are widely used in the process industry. Conventional tube heat exchangers usually consist 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 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. [0003] In order to improve the heat exchange efficiency, it is necessary to incre...
