[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid. Heat exchangers are important equipment in chemical, petroleum, power, food and general industries. The corrugated tube is a relatively important component of the heat exchanger during normal operation. When using the heat exchanger corrugated tube, it needs to be supported by a support structure.

[0003] Chinese patent CN203464812U discloses a baffle-free corrugated tube heat exchanger, comprising a cylindrical body and corrugated heat exchange tubes. Each set of peaks and troughs on the corrugated heat exchange tubes constitutes a corrugation. The cross-section of the corrugated heat exchange tubes perpendicular to the axis is circular, and the peaks at corresponding positions on adjacent corrugated heat exchange tubes contact and support each other. This baffle-free corrugated tube heat exchanger eliminates the baffle and baffle rod structures and uses a corrugated tube structure for mutual support, which not only improves thermal efficiency but also reduces the manufacturing cost of the heat exchanger and the overall operating cost.

[0004] However, this technical solution has the problems of inconvenience in fixing the corrugated tubes of different lengths on the support plate, and the corrugated tubes are prone to wear. Therefore, there is an urgent need for wear-resistant support components for heat exchanger corrugated tubes. Utility Model Content

[0007] Specifically, the support component includes an upper bonding plate, a lower bonding plate, two locking nuts, and an anti-wear washer. Both the upper and lower bonding plates have mounting grooves in their middle that are adapted to the shape of the corrugated tube. After the upper and lower bonding plates are fastened together, they are attached to the outer edge of the corrugated tube. The anti-wear washer is installed in the middle of the upper and lower bonding plates and is in close contact with the inner diameter of the mounting hole. The two locking nuts are located on both sides of the mounting hole and are threaded to the outer circumference of the upper and lower bonding plates after fastening, for fixing the position of the upper and lower bonding plates in the mounting hole after installation.

[0008] Specifically, the upper bonding plate and the lower bonding plate are fixedly provided with two sets of semi-threads on their outer circumferences. The semi-threads of the upper bonding plate and the corresponding semi-threads of the lower bonding plate together form a complete external thread. The locking nut has an internal thread that matches the external thread on its inner side.

[0009] Specifically, the locking nut includes an inner ring and an outer hexagon, with the inner ring and outer hexagon being fixedly installed.

[0010] Specifically, the inner ring is fixedly provided with a plurality of top rods arranged in a ring around the inner ring as the axis on the end face near the mounting hole.

[0011] Specifically, the anti-wear pad is cylindrical and can be freely inserted into the outer periphery of the upper and lower bonding plates after they are fastened together.

[0012] Specifically, the anti-wear pad is made of rubber.

[0013] Specifically, the outer diameter of the locking nut is larger than the diameter of the mounting hole.

[0014] Compared with the prior art, the wear-resistant support for the heat exchanger bellows of this invention has at least the following advantages:

[0015] This utility model utilizes two locking nuts in conjunction with the upper and lower bonding plates after fastening, facilitating the fixing of the upper and lower bonding plates within the mounting holes after installation, thereby facilitating the fixing of the corrugated tube on the support plate.

[0025] This embodiment discloses a wear-resistant support for a heat exchanger bellows tube, such as... Figure 1-6 As shown, it includes a circular support plate 1, on which a plurality of mounting holes 15 are arranged in a ring around the support plate 1. A corrugated tube 2 is placed in each of the mounting holes 15. A support component is installed between the mounting holes 15 and the corrugated tube 2 for supporting and fixing the corrugated tube 2 in the support plate 1. Hollow direct connectors 6 are fixedly connected to both sides of the corrugated tube 2. The direct connectors 6 are connected to the pipes on the inner wall of the external heat exchanger.

[0026] The supporting components include an upper bonding plate 11, a lower bonding plate 10, two locking nuts, and an anti-wear washer 5. The upper bonding plate 11 and the lower bonding plate 10 each have a mounting groove 8 in the middle that matches the shape of the corrugated tube 2. After the upper bonding plate 11 and the lower bonding plate 10 are fastened together, they are attached to the outer edge of the corrugated tube 2. The anti-wear washer 5 is installed in the middle of the upper bonding plate 11 and the lower bonding plate 10 and is in close contact with the inner diameter of the mounting hole 15. The two locking nuts are located on both sides of the mounting hole 15 and are threaded to the outer circumference of the upper bonding plate 11 and the lower bonding plate 10 after fastening together, for fixing the position of the upper bonding plate 11 and the lower bonding plate 10 in the mounting hole 15 after installation.

[0027] Two sets of semi-threads 9 are fixedly provided on the outer circumference of the upper bonding plate 11 and the lower bonding plate 10. The semi-threads 9 of the upper bonding plate 11 and the corresponding semi-threads 9 of the lower bonding plate 10 together form a complete external thread. The inner side of the locking nut has an internal thread 14 that matches the external thread. According to the installation position of the corrugated tube 2 on the support plate 1 in the heat exchanger, the upper bonding plate 11 and the lower bonding plate 10 are fastened to the required installation position of the corrugated tube 2. Then, the position of the upper bonding plate 11 and the lower bonding plate 10 after fastening is fixed by the cooperation of the internal thread 14 and the external thread. The inner side of the upper bonding plate 11 and the lower bonding plate 10 in the length direction is chamfered 13 to facilitate fastening the upper bonding plate 11 and the lower bonding plate 10 to the outer side of the corrugated tube 2.

[0028] The locking nut includes an inner ring 3 and an outer hexagon 7. The inner ring 3 and the outer hexagon 7 are fixedly set. The distance between the locking nut and the support plate 1 can be adjusted by using a hex wrench to adjust the outer hexagon 7.

[0029] Multiple push rods 4 are fixedly installed on the end face of the inner ring 3 near the mounting hole 15, arranged in a ring around the inner ring 3. The push rods 4 at this location contact the end face of the support plate 1, thereby fixing the position of the bellows tube 2 on the support plate 1 by two locking nuts.

[0030] The anti-wear pad 5 is cylindrical and can be freely inserted into the outer periphery of the upper bonding plate 11 and the lower bonding plate 10 after they are fastened together, so as to facilitate changing the position of the anti-wear pad 5 on the upper bonding plate 11 and the lower bonding plate 10.

[0031] The wear-resistant pad 5 is made of rubber, and the wear-resistant pad 5 made of rubber has wear-resistant characteristics.

[0032] The outer diameter of the locking nut is larger than the diameter of the mounting hole 15, which facilitates fixing the upper bonding plate 11 and the lower bonding plate 10 in the mounting hole 15 by means of the two locking nuts.

[0033] In use, the two locking nuts and the anti-wear gasket 5 are first inserted into the bellows 2. According to the installation position of the bellows 2 on the support plate 1 inside the heat exchanger, the upper bonding plate 11 and the lower bonding plate 10 are fastened to the required installation position of the bellows 2. The anti-wear gasket 5 is inserted into the outer peripheral end face of the upper bonding plate 11 and the lower bonding plate 10 after fastening. Then, one end of the locking nut is installed on the outer periphery of the upper bonding plate 11 and the lower bonding plate 10 after fastening. The anti-wear gasket 5 is inserted into the mounting hole 15 and the middle position of the anti-wear gasket 5 is adjusted to align with the middle position of the mounting hole 15. Finally, the locking nut is rotated to fix the position of the bellows 2 on the support plate 1.
