[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes.
[0003] In the existing technology, heat exchangers are large in size, making them difficult to operate in relatively small spaces. Furthermore, when a heat exchanger is damaged, the entire unit needs to be replaced, which increases maintenance costs. Utility Model Content
[0004] The purpose of this utility model is to provide a foldable heat exchanger suitable for confined spaces, in order to solve the problems mentioned in the background art, such as the large size of the heat exchanger, which makes it difficult to operate in confined spaces, and the increased maintenance costs due to the need to replace the entire heat exchanger when it is damaged.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a heat exchange mechanism comprising a modular heat exchange frame, a heat exchange tube, and an internally threaded connector. Stabilizing mechanisms are provided at both the upper and lower ends of the heat exchange mechanism. Each stabilizing mechanism includes a stabilizing plate, a moving groove, a sliding groove, a moving plate, a threaded groove, a threaded rod, a rotary knob, and a rubber gasket. A connecting assembly is provided on one side of the heat exchange mechanism, comprising a stainless steel corrugated pipe, a threaded connecting block, and a connecting groove.
[0006] In a preferred embodiment, the modular heat exchange frame is provided with heat exchange tubes inside, and the connection points on both sides of the modular heat exchange frame are fixedly connected to one end of an internal threaded connector.
[0007] In a preferred embodiment, both the upper and lower ends of the modular heat exchange rack are fixedly connected to one end of the stabilizing plate, and the stabilizing plate has a moving groove inside.
[0008] In a preferred embodiment, sliding grooves are provided on both sides of the moving groove, and one side of the stabilizing plate is fixedly connected to one side of the moving plate.
[0009] In a preferred embodiment, the inner wall of the movable groove is movably connected to the outer wall of the movable plate, and a threaded groove is provided on the side of the movable plate away from the movable plate.
[0010] In a preferred embodiment, the inner wall of the threaded groove is threadedly connected to the outer wall of the threaded rod, and the outer wall of the threaded rod is movably connected to the inner wall of the groove.
[0011] In a preferred embodiment, one end of the threaded rod is fixedly connected to one end of the rotary knob, and the end of the rotary knob near the threaded rod is fixedly connected to one side of the rubber gasket.
[0012] In a preferred embodiment, one side of the modular heat exchanger is movably connected to one side of the stainless steel corrugated pipe, and both ends of the stainless steel corrugated pipe are fixedly connected to one end of the threaded connecting block. The outer wall of the threaded connecting block is movably connected to the inner wall of the internal threaded connector, and a connecting groove is provided inside the threaded connecting block.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, the threaded connecting block is first rotated into the interior of the internal threaded connecting head, while the moving plate enters the interior of the moving groove, and the threaded rod enters the interior of the sliding groove. The modular heat exchange frame is moved according to the size of the space. The stainless steel corrugated pipe maintains the connection device when the modular heat exchange frame moves with each other. The connection of the stainless steel corrugated pipe allows the whole device to be folded, making the device suitable for relatively small spaces.
[0015] 2. In this utility model, when the modular heat exchanger frame moves, the moving plate moves inside the moving groove, while the threaded rod moves inside the sliding groove. After the modular heat exchanger frames have moved relative to each other, the threaded rod is rotated by rotating the rubber pad, causing the threaded rod to move inside the threaded groove. The movement of the threaded rod causes the rotating knob and the rubber pad to press against both sides of the stabilizing plate, thereby stabilizing the moving plate and thus stabilizing the moved modular heat exchanger frame. With the modular heat exchanger frame setup, if one set of modular heat exchanger frames is damaged, only one set of modular heat exchanger frames needs to be replaced, thereby reducing maintenance costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 This utility model provides a technical solution including: a heat exchange mechanism 1, which includes a modular heat exchange frame 101, a heat exchange tube 102, and an internal threaded connector 103. Both the upper and lower ends of the heat exchange mechanism 1 are provided with stabilizing mechanisms 2, which include a stabilizing plate 201, a moving groove 202, a sliding groove 203, a moving plate 204, a threaded groove 205, a threaded rod 206, a rotary knob 207, and a rubber gasket 208. A connecting component 3 is provided on one side of the heat exchange mechanism 1, which includes a stainless steel corrugated pipe 301, a threaded connecting block 302, and a connecting groove 303.
[0025] In one embodiment, a heat exchange tube 102 is provided inside the modular heat exchange frame 101. The connection points on both sides of the modular heat exchange frame 101 are fixedly connected to one end of the internal threaded connector 103. The upper and lower ends of the modular heat exchange frame 101 are fixedly connected to one end of the stabilizing plate 201. The stabilizing plate 201 has a moving groove 202 inside. The moving groove 202 has sliding grooves 203 on both sides. One side of the stabilizing plate 201 is fixedly connected to one side of the moving plate 204. The inner wall of the moving groove 202 is movably connected to the outer wall of the moving plate 204. The side of the moving plate 204 away from the moving plate 204 has a threaded groove 205 inside. The inner wall of the threaded groove 205 is threadedly connected to the outer wall of the threaded rod 206. The outer wall of the threaded rod 206 is movably connected to the inner wall of the sliding groove 203. One end of the threaded rod 206 is fixedly connected to one end of the rotary knob 207. The end of the rotary knob 207 near the threaded rod 206 is fixedly connected to one side of the rubber gasket 208.
[0026] Specifically: When the modular heat exchanger 101 moves, the moving plate 204 moves inside the moving groove 202, while the threaded rod 206 moves inside the sliding groove 203. After the modular heat exchangers 101 have moved relative to each other, the threaded rod 206 is rotated by rotating the rubber pad 208, causing the threaded rod 206 to move inside the threaded groove 205. The movement of the threaded rod 206 causes the rotating knob 207 and the rubber pad 208 to press against both sides of the stabilizing plate 201, thereby stabilizing the moving plate 204 and thus stabilizing the moved modular heat exchanger 101. With the modular heat exchanger 101 in place, if one set of modular heat exchangers 101 is damaged, only one set of modular heat exchangers 101 needs to be replaced, thereby reducing maintenance costs.
[0027] In one embodiment, one side of the modular heat exchange rack 101 is movably connected to one side of the stainless steel corrugated pipe 301, and both ends of the stainless steel corrugated pipe 301 are fixedly connected to one end of the threaded connecting block 302. The outer wall of the threaded connecting block 302 is movably connected to the inner wall of the internal threaded connector 103, and a connecting groove 303 is provided inside the threaded connecting block 302.
[0028] Specifically: the threaded connecting block 302 rotates into the interior of the internal threaded connecting head 103, while the moving plate 204 enters the interior of the moving groove 202, and the threaded rod 206 enters the interior of the sliding groove 203. The modular heat exchanger 101 moves according to the size of the space. The stainless steel corrugated pipe 301 keeps the connection device in place when the modular heat exchanger 101 moves. The connection of the stainless steel corrugated pipe 301 allows the entire device to be folded, making the device suitable for relatively small spaces.
[0029] Working principle: First, the threaded connecting block 302 is rotated into the internal threaded connecting head 103. At the same time, the moving plate 204 enters the moving groove 202, and the threaded rod 206 enters the sliding groove 203. The modular heat exchange frame 101 moves according to the size of the space. The stainless steel corrugated pipe 301 maintains the connection device when the modular heat exchange frame 101 moves. When the modular heat exchange frame 101 moves, the moving plate 204 moves inside the moving groove 202, and the threaded rod 206 moves inside the sliding groove 203. After the modular heat exchange frame 101 moves, the threaded rod 206 is rotated by rotating the rubber pad 208, so that the threaded rod 206 moves inside the threaded groove 205. The movement of the threaded rod 206 drives the rotating knob 207 and the rubber pad 208 to squeeze the two sides of the stabilizing plate 201, thereby stabilizing the moving plate 204 and thus stabilizing the moved modular heat exchange frame 101.
[0030] 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.
