Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, and specifically relates to a heat exchanger that increases heat exchange efficiency. Background Technology

[0002] A heat exchanger is a device that enables heat transfer between fluids at different temperatures. Through heat transfer methods such as conduction and convection, it transfers heat from a higher-temperature fluid to a lower-temperature fluid, thereby meeting the needs of heating, cooling, condensation, or evaporation in a process. It is widely used in chemical, petroleum, power, metallurgical, food, and refrigeration industries, and is one of the core devices in energy utilization and thermal management systems.

[0003] Existing heat exchangers typically have internal filters to filter the fluid entering the device for heat exchange. However, over time, these filters can become clogged, affecting heat exchange efficiency, reducing the device's operating efficiency, and causing inconvenience to users. Therefore, we need to upgrade and modify existing technologies. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown in Figure 5, this embodiment provides a heat exchanger for increasing heat exchange efficiency, including a device body 1. The device body 1 contains an outer shell 2 and a tube box 3. The tube box 3 is provided with a first pipe 4 and a second pipe 5. The outer shell 2 is provided with a third pipe 6 and a fourth pipe 7. One end of the outer shell 2 and the tube box 3 is connected to a fixed plate 12. A docking plate 13 is provided between the fixed plates 12. The front end of the docking plate 13 is connected to a filter screen 14, and a fixed post 16 is inserted into the docking plate 13. A nut 18 is screwed onto the fixed post 16. The outer shell 2 is provided with a heat transfer tube 10 and a baffle plate 11. A fixed seat 19 and a fixed frame 20 are provided below the outer shell 2. A screw rod 21 is provided in the fixed seat 19 and the fixed frame 20. One end of the screw rod 21 is connected to a motor 22, and a support 23 is screwed onto the screw rod 21.

[0025] Preferably, lifting rings 8 are provided on the outer casing 2 and the tube box 3. The lifting rings 8 are fixedly connected to the outer casing 2 and the tube box 3. By providing lifting rings 8, it is convenient for users to move and relocate the device, which provides convenience for users. A nameplate box 9 is provided on the outer wall of the front end of the outer casing 2. The nameplate box 9 is fixedly connected to the outer casing 2. By providing nameplate box 9, it is convenient for users to place equipment usage information in the nameplate box 9 for reference, which increases the practicality and convenience of the device.

[0026] Preferably, a sealing ring 15 is provided at the rear end of the docking plate 13. The sealing ring 15 is sealed to the docking plate 13. By providing the sealing ring 15, the sealing performance of the device is increased, ensuring the safety of the device during use and preventing leakage. Multiple sets of fixing columns 16 are provided, and each fixing column 16 is movably fitted with a washer 17. By providing the washer 17, wear on the surface of the device is prevented during the pre-tightening process of the nut 18, thus extending the service life and working time of the device. A guide ring 25 is provided on the support 23, and a guide rod 24 is inserted into the guide ring 25. The guide rod 24 is fixedly connected to the fixed seat 19 and the fixed frame 20. By providing the guide rod 24 and the guide ring 25, the direction of movement of the support 23 can be guided, preventing the support 23 from shifting position during movement and ensuring the safety of the support 23.

[0027] The working principle and operation process of this utility model are as follows: During use, the hot fluid enters the outer casing 2 through pipe 4 (connector 7), and the cold fluid enters the outer casing 2 through pipe 1 (connector 4). It is first filtered by the filter screen 14, and then heat exchanged through the heat transfer tube 10 and baffle 11. The fluid after heat exchange is completed is discharged through pipe 2 (connector 5) and pipe 3 (connector 6). When the filter screen 14 needs to be disassembled and cleaned, the user rotates the nut 18 off the fixing post 16. After removal, the fixing post 16 is pulled out from the connecting plate 13 and the fixing plate 12. After pulling out, the connecting plate 13 separates from the fixing plate 12, allowing the filter screen 14 to be removed. The mesh of the filter screen 14 can then be cleaned. After cleaning, it can be re-fixed. The filter screen 14 of the device is disassembled and cleaned to remove blockages and impurities, restore fluid flow, improve heat transfer efficiency, extend service life, and avoid affecting subsequent heat exchange efficiency. When the position of the support 23 needs to be adjusted horizontally during use, the motor 22 is controlled to run. The motor 22 drives the lead screw 21 to rotate, and the lead screw 21 drives the support 23 to move horizontally on the lead screw 21. When the support 23 moves, the guide ring 25 slides on the guide rod 24 until the support 23 moves to the appropriate position. This allows for horizontal adjustment of the support 23, ensuring the safety and stability of the device during use, improving the applicability of the device, and avoiding forced installation of the heat exchanger due to foundation errors, which could cause flange misalignment or pipe twisting.
