Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, and more particularly to heat exchangers. Background Technology

[0002] A heat exchanger is a device used for heat transfer. Its main function is to convert and utilize energy through heat exchange between two fluids (usually liquids or gases). Heat exchangers are widely used in various industries, such as chemical, energy, HVAC, and food processing.

[0003] Existing technologies, such as the invention disclosed in publication number CN105627634A, present a heat exchanger employing a first cavity and a second cavity. The heat exchanger includes a connecting component comprising at least a first branch pipe and a second branch pipe that are interconnected. The first and second branch pipes are respectively inserted into the first and second cavities, and multiple micropores are formed on the inserted portions of the first and second branch pipes to allow fluid communication between the first and second cavities. In this invention, since the two internal cavities of the heat exchanger are fluidly connected only through a single connecting component, the manufacturing cost of the heat exchanger is reduced, and the sealing reliability of the heat exchanger is improved.

[0004] The inventors discovered in daily use that the interface positions and pipe connection methods of heat exchangers in the prior art are quite complex, especially for large or specially designed heat exchangers, which require precise installation and commissioning to ensure a stable connection. Improper connection can lead to leakage problems. Especially in high-temperature and high-pressure working environments, special attention needs to be paid to the sealing and pressure resistance of the interface between the pipe and the heat exchanger. The heat exchanger itself usually occupies a large space, and the connection method of the external pipe is sometimes limited by the size of the equipment and the installation environment. Moreover, space is limited, and the connection process requires additional adjustments and optimizations.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat exchanger.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a heat exchanger, comprising a heat exchanger body, a mounting bracket, a connecting structure, and an installation structure. A connector is installed at the upper end of the heat exchanger body. The heat exchanger body is connected to the mounting bracket via the installation structure. Two connecting pipes are installed at the upper end of the connector. A connecting pipe is fixedly connected to the arc surface of the heat exchanger body. A fixing member is fixedly connected to the upper end of the connector. A connecting member is fixedly connected to the arc surface at the lower end of the heat exchanger body. The arc surface of the connecting pipe is provided with a connecting structure.

[0008] Preferably, the connecting structure includes a turntable, which is rotatably connected to a connecting pipe. A fixed plate is fixedly connected to the arc surface of the connecting pipe. A sliding groove is formed on the inner wall of the fixed plate. A sliding rod is slidably connected to the inner wall of the sliding groove. An insert plate is fixedly connected to the end of the sliding rod away from the turntable. A connecting ring is slidably connected to the arc surface of the connecting pipe. A pipe is fixedly connected to the inner wall of the connecting ring. The insert plate is slidably connected to the connecting ring. An inclined groove is formed on the inner wall of the turntable. The inclined groove is slidably connected to the sliding rod. A connecting frame is fixedly connected to the arc surface of the fixed plate. A screw is threadedly connected to the inner wall of the connecting frame. The screw abuts against the turntable.

[0009] This preferred solution achieves the following: when connecting a pipe to a connecting pipe, the pipe is pulled to move, which in turn moves the connecting ring. The connecting ring is then aligned with the connecting pipe and inserted into it. A turntable is then rotated, moving a sloping groove, which in turn moves a sliding rod. The sliding rod slides along the inner wall of the groove, which in turn moves an insert plate. The insert plate is then inserted into the connecting ring for fixation. Finally, a screw is rotated to move the screw, which then abuts against the turntable for fixation.

[0010] Preferably, the turntable has a plurality of slots on its arc surface, and the slots are evenly distributed on the turntable. This preferred design increases the friction between the turntable and the hand, preventing slippage when the turntable is rotated.

[0011] Preferably, a plurality of handles are fixedly connected to the arc surface of the screw, and the plurality of handles are evenly distributed on the screw.

[0012] By adopting this preferred solution, the lever can be directly rotated when the screw needs to be rotated, and the lever drives the screw to rotate, making it more convenient to rotate the screw.

[0013] Preferably, a limiting rod is fixedly connected inside the slide groove, and the limiting rod is slidably connected to the slide bar.

[0014] By adopting this preferred solution, the limiting rod can limit the sliding rod, thus preventing the sliding rod from deviating during use.

[0015] Preferably, the arc surface of the heat exchanger body is provided with a support structure, the support structure includes a lead screw, the lead screw is fixedly connected to the heat exchanger body, an auxiliary rod is fixedly connected to the arc surface of the heat exchanger body, a support plate is slidably connected to the arc surface of both the auxiliary rod and the lead screw, a support ring is fixedly connected to one end of the two support plates that are close to each other, and a threaded ring is threadedly connected to the arc surface of the lead screw, the threaded ring is rotatably connected to the support plate.

[0016] By adopting this preferred solution, when pipe support is required, the threaded ring is rotated and moved, the arc surface of the threaded ring screw slides, the threaded ring drives the support plate to move, the support plate drives the support ring to move, and the support ring drives the support plate to move. The two support plates slide on the arc surfaces of the screw and the auxiliary rod respectively, and after moving to the appropriate position, the support ring supports the pipe.

[0017] Preferably, the arc surface of the threaded ring is provided with a plurality of auxiliary grooves, and the plurality of auxiliary grooves are evenly distributed on the threaded ring.

[0018] By adopting this preferred solution, the auxiliary groove can increase the friction between the threaded ring and the hand, thus preventing slippage when rotating the threaded ring.

[0019] Preferably, a protective sleeve, which is a rubber sleeve, is fixedly connected inside the support ring.

[0020] By adopting this preferred solution, the protective sleeve can protect the pipeline and prevent wear and tear during use.

[0021] Preferably, the mounting bracket has an internal mounting structure, which includes a slide rail fixedly connected to the mounting bracket. A fixing block is fixedly connected to the inner wall of the slide rail, and two sliders are slidably connected to the inner wall of the slide rail. A threaded rod is fixedly connected to the side of each slider that is close to the other. A threaded tube is threadedly connected to the side of each threaded rod that is close to the other. Several friction grooves are evenly distributed on the arc surface of the threaded tube. Opposite threads are formed on the inner walls of both ends of the threaded tube. The threaded tube is rotatably connected to the fixing block. A connecting rod is fixedly connected to the side of each slider that is far from the other. A fixing plate is fixedly connected to the end of the connecting rod that is far from the slider. Several inserts are fixedly connected to the side of the fixing plate that is far from the connecting rod. Two sets of several inserts are respectively engaged with the fixing component and the connecting component.

[0022] This preferred solution achieves the following: when it is necessary to connect the heat exchanger body to the mounting bracket, the heat exchanger body is pulled to move, then the fixing parts and connecting parts are located at both ends of the slide rail, and then the threaded pipe is rotated to move. The threaded pipe drives the threaded rod to move, the threaded rod drives the slider to move, the slider slides on the inner wall of the slide rail, the slider drives the connecting rod to move, the connecting rod drives the fixing plate to move, the fixing plate drives the insert block to move, and then the insert block is inserted into the fixing parts and connecting parts for fixation.

[0023] Preferably, a round rod is fixedly connected inside the slide rail, and the round rod is slidably connected to the slider.

[0024] By adopting this preferred solution, the round rod can limit the slider, preventing the slider from deviating when sliding on the inner wall of the slide rail, thus improving the stability of the slider's sliding.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0026] 1. In this invention, by setting up a connection structure, the interface positions and pipe connection methods of heat exchangers in the prior art are relatively complex, especially for large or specially designed heat exchangers. Precise installation and commissioning are required to ensure a stable connection, and improper connection can lead to leakage problems. Especially in high-temperature and high-pressure working environments, special attention needs to be paid to the sealing and pressure resistance of the interface between the pipe and the heat exchanger. The heat exchanger itself usually occupies a large space, and the connection method of the external pipes is sometimes limited by the size of the equipment and the installation environment. Moreover, space is limited, and the connection process requires additional adjustments and optimizations.

[0027] 2. In this invention, by setting up a support structure, the pipe can be easily and quickly supported, and can be supported at an appropriate position according to the weight of the pipe, so as to prevent the pipe from sagging and falling due to its own weight and the weight of the water flow.

[0037] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with 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.

[0038] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0039] Example 1, such as Figure 1-7As shown, the present invention provides a heat exchanger, including a heat exchanger body 1, a mounting bracket, a connecting structure 7, and a mounting structure 9. A connector 3 is installed at the upper end of the heat exchanger body 1. The heat exchanger body 1 is connected to the mounting bracket via the mounting structure 9. Two connecting pipes 2 are installed at the upper end of the connector 3. A connecting pipe 6 is fixedly connected to the arc surface of the heat exchanger body 1. A fixing member 4 is fixedly connected to the upper end of the connector 3. A connecting member 5 is fixedly connected to the arc surface at the lower end of the heat exchanger body 1. The arc surface of the connecting pipe 6 is provided with a connecting structure 7. The arc surface of the heat exchanger body 1 is provided with a supporting structure 8. The mounting bracket is provided with a mounting structure 9 inside.

[0040] The specific settings and functions of its connection structure 7, support structure 8, and installation structure 9 will be discussed below.

[0041] like Figures 2 to 4As shown, the connecting structure 7 includes a turntable 707, which is rotatably connected to the connecting pipe 6. A fixed plate 704 is fixedly connected to the arc surface of the connecting pipe 6. A sliding groove 713 is provided on the inner wall of the fixed plate 704. A sliding rod 711 is slidably connected to the inner wall of the sliding groove 713. An insert plate 705 is fixedly connected to the end of the sliding rod 711 away from the turntable 707. A connecting ring 709 is slidably connected to the arc surface of the connecting pipe 6. A pipe 708 is fixedly connected to the inner wall of the connecting ring 709. The insert plate 705 is slidably connected to the connecting ring 709. An inclined groove 712 is provided on the inner wall of the turntable 707. The inclined groove 712 is slidably connected to the sliding rod 711. A connecting frame 701 is fixedly connected to the arc surface of the fixed plate 704. A screw 702 is threadedly connected to the inner wall of the connecting frame 701. The screw 702 abuts against the turntable 707. When it is necessary to connect pipe 708 to connecting pipe 6, pull pipe 708 to move it. Pipe 708 drives connecting ring 709 to move. Then, align connecting ring 709 with connecting pipe 6 and insert connecting ring 709 into connecting pipe 6. Then, rotate turntable 707 to move it. Turntable 707 drives inclined groove 712 to move. Inclined groove 712 drives sliding rod 711 to move. Sliding rod 711 slides on the inner wall of sliding groove 713. Sliding groove 713 drives insert plate 705 to move. Then, insert plate 705 is inserted into connecting ring 709 for fixation. Then, rotate screw 702 to move it. Then, screw 702 abuts against turntable 707 for fixation. The arc surface of turntable 707 has several slots 706, which are evenly distributed on turntable 707. The slot 706 increases the friction between the turntable 707 and the hand, preventing slippage when rotating the turntable 707. Several levers 703 are fixedly connected to the arc surface of the screw 702, and these levers 703 are evenly distributed on the screw 702. When it is necessary to rotate the screw 702, the levers 703 can be directly rotated, causing the screw 702 to rotate. The levers 703 make rotating the screw 702 more convenient. A limiting rod 710 is fixedly connected inside the slide groove 713, and the limiting rod 710 is slidably connected to the slide rod 711. The limiting rod 710 can limit the slide rod 711, preventing it from shifting during further use.

[0042] The effect of the entire connection structure 7 is that it can easily connect and disassemble the connecting pipe 6 and the pipe 708 quickly, which not only facilitates regular cleaning and maintenance, but also reduces maintenance and installation costs.

[0043] like Figure 1 and Figure 5As shown, the support structure 8 includes a lead screw 83, which is fixedly connected to the heat exchanger body 1. An auxiliary rod 87 is fixedly connected to the arc surface of the heat exchanger body 1. Support plates 86 are slidably connected to both the auxiliary rod 87 and the arc surface of the lead screw 83. Support rings 81 are fixedly connected to the ends of the two support plates 86 that are close to each other. A threaded ring 84 is threadedly connected to the arc surface of the lead screw 83. The threaded ring 84 is rotatably connected to the support plate 86. When support is needed for pipe 708, the threaded ring 84 is rotated and moved. The arc surface of the threaded ring 84's lead screw 83 slides, causing the threaded ring 84 to move the support plate 86. The support plate 86 then moves the support ring 81, which in turn moves the support plate 86. The two support plates 86 slide on the arc surfaces of the lead screw 83 and the auxiliary rod 87, respectively. After moving to the appropriate position, the support ring 81 supports pipe 708. The arc surface of the threaded ring 84 has several auxiliary grooves 85, which are evenly distributed on the threaded ring 84. The auxiliary grooves 85 increase the friction between the threaded ring 84 and the hand, preventing slippage when rotating the threaded ring 84. A protective sleeve 82, made of rubber, is fixedly connected inside the support ring 81. The protective sleeve 82 protects pipe 708 from wear during use.

[0044] The overall support structure 8 achieves the following effect: it can quickly and easily support the pipe 708, and can support it at an appropriate position according to the weight of the pipe 708, so as to prevent the pipe 708 from sagging and falling due to its own weight and the weight of the water flow.

[0045] like Figure 6 and Figure 7As shown, the mounting structure 9 includes a slide rail 901, which is fixedly connected to the mounting bracket. A fixing block 907 is fixedly connected to the inner wall of the slide rail 901. Two sliders 902 are slidably connected to the inner wall of the slide rail 901. Threaded rods 906 are fixedly connected to the sides of the two sliders 902 that are close to each other. A threaded tube 909 is threadedly connected to the sides of the two threaded rods 906 that are close to each other. The arc surface of the threaded tube 909 has several friction grooves 910 evenly spaced. Distributed on the threaded tube 909, the inner walls of both ends of the threaded tube 909 are provided with opposite threads. The threaded tube 909 is rotatably connected to the fixed block 907. The two sliders 902 are fixedly connected to the side away from each other with connecting rods 903. The end of the connecting rod 903 away from the slider 902 is fixedly connected to the fixed plate 904. The side of the fixed plate 904 away from the connecting rod 903 is fixedly connected to several inserts 905. The two sets of several inserts 905 are respectively engaged with the fixed part 4 and the connecting part 3. When it is necessary to connect the heat exchanger body 1 to the mounting bracket, pull the heat exchanger body 1 to move it. Then, position the fixing part 4 and the connecting part 5 at both ends of the slide rail 901. Then, rotate the threaded tube 909 to move it. The threaded tube 909 drives the threaded rod 906 to move, and the threaded rod 906 drives the slider 902 to move. The slider 902 slides on the inner wall of the slide rail 901. The slider 902 drives the connecting rod 903 to move, and the connecting rod 903 drives the fixing plate 904 to move. The fixing plate 904 drives the insert block 905 to move, and then the insert block 905 is inserted into the fixing part 4 and the connecting part 5 for fixation. A round rod 908 is fixedly connected inside the slide rail 901, and the round rod 908 is slidably connected to the slider 902. The round rod 908 can limit the slider 902, preventing the slider 902 from deviating when sliding on the inner wall of the slide rail 901, thus improving the stability of the slider 902's sliding.

[0046] The overall installation structure 9 achieves the effect of facilitating the quick installation of the heat exchanger body 1, avoiding the troublesome process of moving, disassembling and replacing the heat exchanger body 1, and greatly improving the connection efficiency between the heat exchanger body 1 and the mounting bracket.

[0047] The overall working principle is as follows: When it is necessary to connect pipe 708 to connecting pipe 6, pipe 708 is pulled to move, which in turn moves connecting ring 709. Connecting ring 709 is then aligned with connecting pipe 6 and inserted into connecting pipe 6. Turntable 707 is then rotated, moving inclined groove 712. Inclined groove 712 moves sliding rod 711, which slides against the inner wall of groove 713. Groove 713 moves insert plate 705, which then... 05. Insert the connecting ring 709 for fixation, then rotate the screw 702 to move it. The screw 702 then abuts against the turntable 707 for fixation. The slot 706 can increase the friction between the turntable 707 and the hand to prevent slippage when rotating the turntable 707. When it is necessary to rotate the screw 702, the handle 703 can be rotated directly. The handle 703 drives the screw 702 to rotate, making it easier to rotate the screw 702. The limiting rod 710 can limit the slide rod 711 to prevent the slide rod 711 from deviating during use.

[0048] When support is needed for pipe 708, the threaded ring 84 is rotated to move it. The arc surface of the threaded ring 84 screw 83 slides, and the threaded ring 84 drives the support plate 86 to move. The support plate 86 drives the support ring 81 to move, and the support ring 81 drives the support plate 86 to move. The two support plates 86 slide on the arc surfaces of the screw 83 and the auxiliary rod 87, respectively. After moving to the appropriate position, the support ring 81 supports pipe 708. The auxiliary groove 85 can increase the friction between the threaded ring 84 and the hand to prevent slippage when rotating the threaded ring 84. The protective sleeve 82 can protect pipe 708 to prevent wear during use.

[0049] When it is necessary to connect the heat exchanger body 1 to the mounting bracket, pull the heat exchanger body 1 to move it, then place the fixing part 4 and the connecting part 5 at both ends of the slide rail 901, and then rotate the threaded tube 909 to move it. The threaded tube 909 drives the threaded rod 906 to move, and the threaded rod 906 drives the slider 902 to move. The slider 902 slides on the inner wall of the slide rail 901. The slider 902 drives the connecting rod 903 to move, and the connecting rod 903 drives the fixing plate 904 to move. The fixing plate 904 drives the insert block 905 to move, and then the insert block 905 is inserted into the fixing part 4 and the connecting part 5 for fixation. The round rod 908 can limit the slider 902 to prevent the slider 902 from deviating when sliding on the inner wall of the slide rail 901, thereby improving the stability of the slider 902 sliding.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention 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 invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
