[0002] Tube fin heat exchanger is a common heat exchange equipment, widely used in the occasion needing to improve heat exchange efficiency. The working principle of this heat exchanger is to increase the heat exchange surface area by the pipeline with fin, so as to improve heat exchange efficiency. In some large heat exchange systems, in order to improve the heat exchange capacity or adapt to different installation conditions, multiple tube fin heat exchanger modules are usually used for splicing, which can be assembled and connected on site to form a larger heat exchange system.
[0003] But common heat exchanger splicing usually adopts welding mode, and welding mode needs special equipment and technology, requires operator to have higher technical level and experience, secondly, welding splicing is permanent, and cannot be easily disassembled after welding, if heat exchanger needs to be overhauled, cleaned or replaced some components, welding mode is difficult to disassemble, which increases the difficulty and cost of later maintenance. INVENTION CONTENTS
[0004] The utility model aims at providing a kind of tube fin heat exchanger splicing structure of turning block sliding block linkage, can be spliced to heat exchanger by the mode of turning block linkage, with good detachability, can be conveniently disassembled when needed.
[0005] The technical scheme adopted by the utility model is as follows:
[0006] A kind of tube fin heat exchanger splicing structure of turning block sliding block linkage, including heat exchanger main body, the both sides of heat exchanger main body are provided with splicing mechanism;The splicing mechanism includes: two circular rings are respectively fixedly connected to the top and bottom of the two sides of adjacent heat exchanger main body;Two splicing discs are respectively rotationally connected to the inside of circular ring;Rotating member is respectively fixedly connected to the outside of rotating member;Fixed plate is fixedly connected to the both sides of heat exchanger main body;One end of telescopic spring is fixedly connected to one side of fixed plate;Clamping block is fixedly connected to the other end of telescopic spring, and clamping block is used in cooperation with rotating member;One end of guide rod is fixedly connected to one side of clamping block, the other end of guide rod is penetrated to the outside of fixed plate, and guide rod is movably arranged in the inside of telescopic spring.
[0007] Preferably, the top of the clamping block is inclined, the angle of the inclined surface is thirty degrees, and the clamping block is used in cooperation with the rotating member.
[0008] Preferably, a balance bar is fixedly connected to both the top and bottom of the snap-fit block, and the other end of the balance bar extends through to one side of the fixing plate.
[0009] Preferably, a limiting member is fixedly connected to the end of the balance bar, and the limiting member is square in shape.
[0010] Preferably, a handle is fixedly connected to the end of the guide rod, and the handle is located on one side of the fixed plate.
[0011] Preferably, a rotating handle is fixedly connected to one side of the rotating component, and the rotating handle is cylindrical.
[0012] The technical effects achieved by this utility model are as follows:
[0013] In this invention, when assembling the heat exchanger body, the rotating component can be driven downwards by rotating the right-side handle. This downward rotation causes the right-side splicing plate to rotate inside the ring. Simultaneously, the right-side splicing plate rotates downwards, pressing and coordinating with the left-side splicing plate to rotate clockwise. When the rotating component rotates 90 degrees, it simultaneously presses the locking block, and under the action of the locking block's inclined surface, it is forced to move outwards. This outward movement of the locking block simultaneously presses and moves the telescopic spring and guide rod outwards, allowing the rotating component to rotate to the bottom of the locking block. Under the elastic force of the telescopic spring, the locking block provides auxiliary restraint on the rotating component, preventing the rotating component and splicing plate from rotating on their own. After the two splicing plates rotate 90 degrees, the two adjacent heat exchanger bodies can be quickly spliced together under the obstruction of the ring. This avoids the disassembly difficulties associated with welding or permanent connections, significantly reducing maintenance costs and downtime, and improving the maintainability of the equipment.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figures 1-3 As shown, a rotating block sliding block linkage type tube-fin heat exchanger splicing structure includes a heat exchanger body 1, with splicing mechanisms provided on both sides of the heat exchanger body 1; the splicing mechanism includes: two rings 201, which are respectively fixedly connected to the top and bottom of adjacent heat exchanger body 1 sides; two splicing plates 202, which are respectively rotatably connected to the inside of the rings 201; rotating parts 203, which are respectively fixedly connected to the outside of the rotating parts 203; a fixing plate 204, which is fixedly connected to both sides of the heat exchanger body 1; and a telescopic spring 205, one end of which is fixedly connected to one side of the fixing plate 204. The snap-fit block 206 is fixedly connected to the other end of the telescopic spring 205 and works in conjunction with the rotating part 203. The guide rod 207 has one end fixedly connected to one side of the snap-fit block 206 and the other end extending through to the outside of the fixing plate 204. The guide rod 207 is movably disposed inside the telescopic spring 205. Through the cooperation of the splicing mechanism, the easy-to-operate mechanical linkage allows for the quick splicing of two adjacent heat exchanger bodies 1 without the need for additional complicated tools or equipment. It is also easy to disassemble, facilitating quick disassembly or adjustment when the heat exchanger body 1 needs cleaning, maintenance, or replacement of parts.
[0021] like Figures 1-3 As shown, the top of the locking block 206 is set as an inclined surface with an angle of thirty degrees. The locking block 206 is used in conjunction with the rotating part 203. When the rotating part 203 rotates, the locking block 206 will squeeze the rotating part 203. Under the action of the inclined surface of the locking block 206, the rotating part 203 can be smoothly rotated to the bottom of the locking block 206. Then, under the elastic force of the telescopic spring 205, the self-locking limit function of the locking block 206 on the rotating part 203 can be strengthened.
[0022] like Figures 1-3 As shown, the top and bottom of the snap-fit block 206 are fixedly connected to a balance bar 301. The other end of the balance bar 301 extends through to one side of the fixed plate 204. When the rotating part 203 presses the snap-fit block 206, the snap-fit block 206 can drive the balance bar 301 to slide inside the fixed plate 204 and make the snap-fit block 206 move in parallel in the parallel direction of the balance bar 301, so as to prevent the snap-fit block 206 from tilting or shifting when the rotating part 203 presses the snap-fit block 206.
[0023] likeFigures 1-3 As shown, a limiting member 302 is fixedly connected to the end of the balance bar 301. The limiting member 302 is square in shape. When the balance bar 301 slides inside the fixed plate 204, in order to prevent the balance bar 301 from falling out of the fixed plate 204, the limiting member 302 can limit and assist the balance bar 301 to stay inside the fixed plate 204.
[0024] like Figures 1-3 As shown, a handle 4 is fixedly connected to the end of the guide rod 207. The handle 4 is located on one side of the fixed plate 204. When it is necessary to separate the two spliced heat exchanger bodies 1, the guide rod 207 can be pulled outward by the handle 4, and the guide rod 207 will drive the locking block 206 to limit the rotating part 203. Then, the rotating part 203 and the splicing plate 202 will be rotated counterclockwise to separate the heat exchanger body 1. The handle 4 can provide a comfortable grip for the operator, so that the operator can easily grab and control the guide rod 207.
[0025] like Figures 1-3 As shown, a rotating handle 5 is fixedly connected to one side of the rotating component 203. The rotating handle 5 is cylindrical in shape. The cylindrical rotating handle 5 improves the ease of operation and avoids discomfort for the operator when rotating. It allows the palm to evenly contact the entire surface, making it easier to apply rotational force to drive the rotating component 203 to rotate smoothly.
[0026] The working principle of this utility model is as follows: When assembling the heat exchanger body 1, the rotating part 203 can be rotated downwards by rotating the right handle 5. The downward rotation of the rotating part 203 can drive the right splicing plate 202 to rotate inside the ring 201. At the same time as the right splicing plate 202 rotates downwards, it can also squeeze and link the left splicing plate 202 to rotate clockwise. When the rotating part 203 rotates 90 degrees, it can simultaneously squeeze the locking block 206. Under the action of the inclined surface of the locking block 206, it can squeeze the locking block 206 to move outwards. After the locking block 206 moves outwards, it can simultaneously squeeze and link the left splicing plate 202 to rotate clockwise. The telescopic spring 205 presses against the guide rod 207 and moves outward, thereby allowing the rotating part 203 to rotate to the bottom of the locking block 206. Under the elastic force of the telescopic spring 205, the locking block 206 can assist in limiting the rotating part 203, preventing the rotating part 203 and the splicing plate 202 from rotating on their own. After the two splicing plates 202 rotate 90 degrees, the two adjacent heat exchanger bodies 1 can be quickly spliced together under the obstruction of the ring 201. This avoids the disassembly difficulties caused by welding or permanent connection methods, which can greatly reduce maintenance costs and downtime, and improve the maintainability of the equipment.
[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
