Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a support structure for a tubular heat exchanger. Background Technique

[0002] A tubular heat exchanger is a device that transmits a heat transfer surface through a tube bundle inside a shell. The fluid is transmitted through the tube bundle, thereby facilitating the conduction of heat inside and reducing the heat inside the device.

[0003] However, when the traditional heat exchanger is installed, the supporting components are prone to friction with the inner tube wall, resulting in damage to the inner tube wall and posing a great potential safety hazard.

[0004] In order to solve the above defects, in the prior art, Chinese Patent No. CN215725403U discloses a support structure for supporting a heat exchanger core and a wound tubular heat exchanger. By designing the support structure to have a base, two bearings, a rotating shaft and rollers, the rotating shaft extends along the axial direction of the core, and the rollers are sleeved on the rotating shaft. In this way, when the core needs to be rotated circumferentially to adjust its position during the general assembly process, the rolling friction occurs between the peripheral wall of the roller of the support structure on the core and the inner peripheral wall of the shell-side cylinder body. Furthermore, the friction between the support structure and the inner peripheral wall of the shell-side cylinder body during the general assembly can be reduced, and the wear of the heat exchange tubes in the core can be reduced, which is beneficial to the long-term operation of the heat exchanger; and the structure of this application is simple and easy to implement, which is beneficial to the stable general assembly of super-large wound tubular heat exchangers.

[0005] The above device uses rollers to roll inside the cylinder during use to reduce wear. However, in the above device, the rollers roll inside the cylinder, and the cylinder is affected by the internal heat conduction, resulting in too high heat at the worn part of the cylinder, thus damaging the inner wall. Therefore, in actual use, the situation that the inner wall of the cylinder is damaged due to the high heat caused by the rotation of the rollers will occur. Content of the Utility Model
