[0032] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0034] Example 1, as Figures 1 to 4As shown, this utility model provides a ball bearing structure for a heat exchanger, including: a tube sheet 1 and a cylinder 2; multiple tubes 102 welded to the surface of the tube sheet 1; and also including: the cylinder 2, with a second flange 201 disposed on the surface of the cylinder 2; a first flange 101 disposed on the outer surface of the tube sheet 1, with multiple bolts 1011 disposed on the surface of the first flange 101; and multiple nuts 1012 threadedly fitted onto the surfaces of the multiple bolts 1011, with the multiple nuts 1012 slidably connected to the surface of the second flange 201.

[0035] In this embodiment, by embedding the tubes 102 and baffles 103 on the surface of the tube sheet 1 inside the cylinder 2, and by embedding the connector 1031 inside the slide rail 202, the mounting holes on the surfaces of flange 101 and flange 201 are quickly aligned. The tube sheet 1 and cylinder 2 are then quickly installed by using bolts 1011 and nuts 1012, thereby improving installation efficiency.

[0036] In Example 2, flange 101 is connected to flange 201. A slide rail 202 is symmetrically located on the inner wall of the cylinder 2. Baffles 103 are welded to the outer surface of multiple pipes 102. Connectors 1031 are welded to one side of each baffle 103. Multiple connectors 1031 are slidably embedded inside the slide rail 202. Limit grooves 1033 are symmetrically located on the inner wall of each connector 1031. Springs 1032 are installed on the inner wall of each connector 1031. One end of each spring 1032 is... A connecting block 1034 is provided, and a limiting block 1035 is provided on the surface of the multiple connecting blocks 1034 at symmetrical locations. The outer surface of the multiple limiting blocks 1035 is slidably embedded in the interior of the limiting groove 1033. A groove 1036 is opened on the side surface of the multiple connecting blocks 1034 away from the connecting member 1031. A positioning shaft 1037 is provided inside the multiple grooves 1036. A ball body 1038 is sleeved on the outer surface of the multiple positioning shafts 1037. The multiple ball bodies 1038 are slidably connected to the inner wall of the slide rail 202.

[0037] In this embodiment, the two ends of the spring 1032 are respectively connected to the surfaces of the connector 1031 and the connecting block 1034, providing a restoring force to the connecting block 1034. At the same time, the limiting groove 1033 limits the limiting block 1035 to prevent it from disengaging. The positioning shaft 1037 inside the groove 1036 positions the ball body 1038, so that during installation or disassembly, the elastic force provided by the spring 1032 allows the ball body 1038 to slide inside the slide rail 202, reducing friction between parts. This reduces friction between components, making operation simple and allowing all parts to be disassembled and replaced for easy maintenance and meeting usage requirements.

[0038] Working principle: In use, the tubes 102 and baffles 103 on the surface of the tube sheet 1 are embedded inside the cylinder 2, and the connector 1031 is embedded inside the slide rail 202, so that the mounting holes on the surfaces of flange 101 and flange 201 are quickly aligned. The tube sheet 1 and cylinder 2 are then quickly installed using bolts 1011 and nuts 1012, improving installation efficiency. Simultaneously, the two ends of the spring 1032 are connected to the surfaces of the connector 1031 and the connecting block 1034 respectively, thus aligning the connecting block 1034. 34 provides a reset force, while the limiting groove 1033 limits the limiting block 1035 to prevent it from dislodging. The positioning shaft 1037 inside the groove 1036 positions the ball body 1038, so that during installation or disassembly, the elastic force provided by the spring 1032 allows the ball body 1038 to slide inside the slide rail 202, reducing friction between parts. This reduces friction between components, making operation simple. All parts can be disassembled and replaced, facilitating maintenance and meeting usage requirements.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
