[0002] A heat exchanger, also known as a heat exchanger, is a device that enables heat transfer between two or more fluids at different temperatures. It is widely used in industrial production such as chemical, petroleum, power, and food processing, serving as a heater, cooler, and condenser. It plays an important role in improving energy efficiency. There are many types of heat exchangers, which can be classified according to their heat transfer principle into indirect contact type, regenerative type, and direct contact type, etc. They have the advantages of compact structure and high heat transfer efficiency.

[0003] Heat exchangers transfer heat from high-temperature fluids to low-temperature fluids, thus avoiding heat waste and improving the energy efficiency of the entire system. Therefore, heat exchangers are essential. Traditional heat exchanger designs are often complex, especially their internal structures such as piping and flange connections, which increase the difficulty of disassembly and assembly. Heat exchangers that are difficult to disassemble and assemble increase the operational difficulty and time costs for maintenance personnel when maintenance or component replacement is required, potentially leading to low maintenance efficiency and even affecting production schedules. Due to the inconvenience of disassembly and assembly, when a heat exchanger malfunctions or requires maintenance, it may require longer downtime for disassembly and reinstallation, which directly impacts the operating efficiency of the production line and the company's economic benefits. Furthermore, the complex structure and heavy weight of traditional heat exchangers during disassembly and assembly may pose safety hazards to operators and increase operational risks.

[0022] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0023] like Figure 1-4 As shown, a heat exchanger that is easy to maintain includes a heat exchanger body 3. Vertical plates 2 and disassembly / removal assembly 4 for installing and disassembling the heat exchanger body 3 are respectively provided on both sides of the heat exchanger body 3. The disassembly / removal assembly 4 includes a mounting plate 41 disposed between the heat exchanger body 3 and a support plate 1, with the inner wall of the mounting plate 41 engaging with one side of the heat exchanger body 3. A connecting block 42 is fixedly connected to the top of the mounting plate 41, and a connecting column 43 is fixedly connected to the bottom of the mounting plate 41. One end of the connecting column 43 is provided with a moving wheel 44 for moving the mounting plate 41, which assists in moving the mounting plate 41 and, in conjunction with the mounting plate 41, enables quick engagement and disassembly of the heat exchanger body 3, facilitating rapid cleaning, inspection, and maintenance. This ensures efficient operation of the heat exchanger and extends its service life, reduces production line downtime, improves production efficiency, lowers maintenance costs, and reduces economic losses caused by downtime.

[0024] Furthermore, a soft buffer layer is provided on the mounting plate 41 to contact the heat exchanger body 3, so as not to squeeze or damage the heat exchanger body 3 during positioning.

[0025] Furthermore, a threaded rod 9 is threadedly connected to the connecting block 42, and a motor 6 is connected to one end of the threaded rod 9. The motor 6 is installed and fixed to the support plate 1. The motor 6 drives the threaded rod 9 to rotate, thereby moving the connecting block 42 and causing the mounting plate 41 to move laterally.

[0026] Specifically, there are two threaded rods 9. One end of the threaded rod 9 is rotatably connected to the vertical plate 2. The motor 6 is coaxially driven to one of the threaded rods 9 through the rotating rod 7, and is also connected to the other threaded rod 9 through multiple gears 8, so as to realize the synchronous rotation of the threaded rods 9 on both sides and improve the stability of the lateral movement of the mounting plate 41.

[0027] Furthermore, a support block 5 is fixedly connected to the support plate 1 on the side away from the heat exchanger body 3, and the motor 6 is installed and fixed on the upper end of the support block 5, which facilitates the fixation of the motor 6.

[0028] Furthermore, the inner wall of the support plate 1 is threaded with a plurality of lead screws 10, and the other end of the lead screw 10 is threaded to the vertical plate 2. A limit nut 11 is threaded on the lead screw 10 to facilitate fixing the support plate 1 and the vertical plate 2 and to provide preload.

[0029] Furthermore, the inner wall of the vertical plate 2 is connected to a connecting pipe 12, which facilitates the transportation of liquid; a flange 17 is installed on the outer side of the connecting pipe 12 for connecting to other pipes.

[0030] Furthermore, a guide rod 15 is connected between the support plate 1 and the upright plate 2, and the connecting block 42 is horizontally slidably connected to the guide rod 15 to provide guidance for the mounting plate 41 and improve the stability of lateral movement. Specifically, a mounting base 13 is fixedly connected to the top of the support plate 1, a fixing base 14 is fixedly connected to the top of the upright plate 2, both ends of the guide rod 15 are fixedly connected to the fixing base 14 and the mounting base 13 respectively, a sleeve 16 is fixedly connected to the connecting block 42, and the outer wall of the guide rod 15 is slidably connected to the sleeve 16 to improve smoothness and service life.

[0031] Working Principle: Based on thermodynamic principles, heat exchange occurs between two or more fluids at different temperatures without direct mixing, utilizing the metal wall or direct contact to achieve heating or cooling, thereby improving energy utilization. When maintenance of the heat exchanger body 3 is required, the motor 6 is turned on. The rotation of the motor 6 drives the rotating rod 7 to rotate, which in turn drives the gear 8 and threaded rod 9 to rotate. As the threaded rod 9 rotates, it moves the connecting block 42. During this movement, the sleeve 16 on one side of the connecting block 42 slides and is limited outside the guide rod 15. The bottom of the connecting block 42 is supported by the connecting column 43 and the moving wheel 44. The connection is facilitated by the rolling of the movable wheel 44 on the ground, which makes it easy to move the mounting plate 41. When the mounting plate 41 is away from the heat exchanger body 3, the heat exchanger body 3 will no longer be subjected to clamping force on one side, allowing the heat exchanger body 3 to be disassembled for maintenance. The support plate 1 facilitates the fixing of the support block 5 and the mounting base 13. The upright plate 2 facilitates the connection of the connecting pipe 12. The heat exchanger body 3 is mainly used to realize the transfer and distribution of heat. It achieves the purpose of heating, cooling, condensation, evaporation, etc. by exchanging heat between two or more fluids at different temperatures without direct mixing, thereby improving energy utilization and reducing energy consumption.
