Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to an integrated heat exchanger for a heat pump system. Background Technology

[0002] In a heat pump system, the integrated heat exchanger is a core component that integrates multiple independent heat exchange functions in a traditional heat pump. Its core function is to solve the problems of inefficiency, large footprint, and system complexity of traditional discrete heat exchangers through structural optimization and functional integration, and ultimately achieve the goal of miniaturization, high efficiency, and energy saving of the heat pump system.

[0003] In existing heat pump systems, most heat exchangers are rigidly connected to upstream and downstream pipes by welding or flanges during use, rather than detachable quick-connect couplings. If a thorough offline cleaning is required, the heat exchanger needs to be removed and transported to the cleaning site, which requires cutting or disassembling a large number of pipes. This is not only time-consuming, but may also cause system leaks due to the re-welding of the pipes.

[0004] Therefore, an integrated heat exchanger for heat pump systems is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an integrated heat exchanger for a heat pump system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated heat exchanger for a heat pump system, comprising a heat exchanger, wherein a frame is fixedly connected to all four sides of the heat exchanger, and an adjustment component is fixedly connected to the top of the frame; The adjusting assembly includes a worm gear, the bottom of which is fixedly connected to the top wall of the frame. A worm is meshed with the top of the worm gear, and a motor is fixedly connected to one end of the worm. A positioning block is mounted on the top of the worm, and a cleaning assembly is hinged to the top of the positioning block. The cleaning assembly includes a horizontal plate, which is hinged to the surface of the positioning block. An electric telescopic shaft is fixedly connected to the bottom end of the horizontal plate, and a scraper is fixedly connected to the bottom end of the electric telescopic shaft. The scraper slides on the surface of the heat exchanger.

[0007] Preferably, arc-shaped blocks are fixedly connected to both sides of the worm gear, and a sliding shaft is slidably connected to the top of the arc-shaped blocks. The top of the sliding shaft is fixedly connected to the bottom of the positioning block. The trajectory of the sliding groove is perfectly matched with the rotation arc of the worm gear, which can forcibly constrain the movement path of the positioning block and prevent angle adjustment deviation caused by the meshing gap between the worm and the worm gear or the weight of the cleaning component.

[0008] Preferably, the surface of the arc-shaped block is provided with a groove, and the sliding shaft slides inside the groove. Since the trajectory of the groove is perfectly matched with the rotation arc of the worm wheel, the movement path of the positioning block can be forcibly constrained, preventing angle adjustment deviations caused by the meshing gap between the worm and the worm wheel or the weight of the cleaning component.

[0009] Preferably, the top two sides of the scraper are fixedly connected to telescopic shafts, the top of the telescopic shafts are fixedly connected to the bottom of the horizontal plate, and the telescopic shafts provide auxiliary support from both sides to ensure that the scraper always remains horizontal or parallel to the heat exchange surface, thereby improving the cleanliness and flatness.

[0010] Preferably, the frame is hinged with locking blocks on all sides, and the scraper has a soft pad attached to the side near the heat exchanger, which facilitates the connection of the heat exchanger to external equipment.

[0011] Preferably, a round shaft is fixedly connected to the bottom of the sliding shaft, and the round shaft slides inside the sliding groove. The soft pad can transform the rigid contact between the scraper and the heat exchanger surface into a flexible contact, preventing the scraper from scratching the surface of the heat exchange tube fins or scraping off the anti-corrosion coating on the fin surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a motor to drive a worm gear to rotate. Since the bottom of the worm wheel is fixed to the top wall of the frame, the worm gear does not rotate during rotation, allowing it to adjust its direction along the arc of the worm wheel. A positioning block connects the worm gear and the cleaning assembly, facilitating simultaneous movement of the cleaning assembly as the worm gear adjusts its direction. By adjusting the direction of the cleaning assembly, both sides of the heat exchanger can be cleaned. Activating the electric telescopic shaft drives the scraper to lift and lower. Cleaning can be completed without cutting or disassembling a large number of pipes, avoiding system leaks caused by re-welding the pipes. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] Please see Figure 1 - Figure 4 The integrated heat exchanger for the heat pump system includes a heat exchanger 1. A frame 4 is fixedly connected to all four sides of the heat exchanger 1. An adjustment component 2 is fixedly connected to the top of the frame 4. The adjustment component 2 includes a worm gear 21. The bottom of the worm gear 21 is fixedly connected to the top wall of the frame 4. A worm 22 is meshed with the top of the worm gear 21. A motor 23 is fixedly connected to one end of the worm 22. A positioning block 24 is installed on the top of the worm 22. A cleaning component 3 is hinged to the top of the positioning block 24. The cleaning component 3 includes a horizontal plate 31. The horizontal plate 31 is hinged to the surface of the positioning block 24. An electric telescopic shaft 32 is fixedly connected to the bottom end of the horizontal plate 31. A scraper 34 is fixedly connected to the bottom end of the electric telescopic shaft 32. The scraper 34 slides on the surface of the heat exchanger 1.

[0018] The worm gear 22 can be rotated by starting the motor 23. Since the bottom of the worm wheel 21 is fixed to the top wall of the frame 4, the worm gear 22 will not rotate during rotation, allowing it to adjust its direction along the arc of the worm wheel 21. The positioning block 24 can be used to connect the worm gear 22 and the cleaning component 3 together, so that the cleaning component 3 can be moved synchronously while the worm gear 22 adjusts its direction. By adjusting the direction of the cleaning component 3, the two sides of the heat exchanger 1 can be cleaned. The electric telescopic shaft 32 can be started to drive the scraper 34 to lift and lower. The cleaning can be completed without cutting or disassembling a large number of pipes, avoiding system leakage caused by re-welding of pipes.

[0019] Please see Figure 1 - Figure 4Both sides of the worm gear 21 are fixedly connected to arc-shaped blocks 25. The top of the arc-shaped blocks 25 is slidably connected to a sliding shaft 26. The top of the sliding shaft 26 is fixedly connected to the bottom of the positioning block 24. The surface of the arc-shaped blocks 25 is provided with a sliding groove 27. The sliding shaft 26 slides inside the sliding groove 27. Both sides of the top of the scraper 34 are fixedly connected to telescopic shafts 33. The top of the telescopic shafts 33 is fixedly connected to the bottom of the horizontal plate 31. The periphery of the frame 4 is hinged with locking blocks 5. A soft pad is attached to the side of the scraper 34 near the heat exchanger 1. The bottom of the sliding shaft 26 is fixedly connected to a round shaft. The round shaft slides inside the sliding groove 27. The round shaft at the bottom of the sliding shaft 26 will slide along the sliding groove 27 of the arc-shaped blocks 25. Since the trajectory of the sliding groove 27 is perfectly matched with the rotation arc of the worm gear 21, it can force The movement path of the positioning block 24 is constrained to prevent angle adjustment deviation caused by the meshing clearance between the worm gear 22 and the worm wheel 21 or the weight of the cleaning component 3. Since the trajectory of the slide groove 27 is perfectly matched with the rotation arc of the worm wheel 21, the movement path of the positioning block 24 can be forcibly constrained to prevent angle adjustment deviation caused by the meshing clearance between the worm gear 22 and the worm wheel 21 or the weight of the cleaning component 3. The telescopic shaft 33 provides auxiliary support from both sides to ensure that the scraper 34 always remains horizontal or parallel to the heat exchange surface, improving the cleaning flatness and facilitating the connection of the heat exchanger 1 to the peripheral equipment by the locking block 5. The soft pad can transform the rigid contact between the scraper 34 and the surface of the heat exchanger 1 into a flexible contact, preventing the scraper 34 from scratching the surface of the heat exchange tube fins or scraping off the anti-corrosion coating on the fin surface.

[0020] Working principle: Starting the motor 23 drives the worm gear 22 to rotate. Since the bottom of the worm wheel 21 is fixed to the top wall of the frame 4, the worm gear 22 does not rotate during rotation, allowing it to adjust its direction along the arc of the worm wheel 21. The positioning block 24 connects the worm gear 22 and the cleaning assembly 3, facilitating the simultaneous movement of the cleaning assembly 3 while the worm gear 22 adjusts its direction. By adjusting the direction of the cleaning assembly 3, both sides of the heat exchanger 1 can be cleaned. Activating the electric telescopic shaft 32 drives the scraper 34 to lift and lower, completing the cleaning without cutting or disassembling a large number of pipes, thus avoiding system leaks caused by re-welding the pipes. Because the trajectory of the chute 27 is consistent with the worm gear... The rotation arc of wheel 21 is perfectly matched, which can forcibly constrain the movement path of positioning block 24 and prevent angle adjustment deviation caused by the meshing gap between worm 22 and worm wheel 21 or the weight of cleaning component 3. Since the trajectory of slide groove 27 is perfectly matched with the rotation arc of worm wheel 21, the movement path of positioning block 24 can be forcibly constrained, preventing angle adjustment deviation caused by the meshing gap between worm 22 and worm wheel 21 or the weight of cleaning component 3. The telescopic shaft 33 provides auxiliary support from both sides to ensure that scraper 34 always remains horizontal or parallel to the heat exchange surface, improving the cleaning flatness and facilitating the connection of heat exchanger 1 to external equipment by locking block 5. The soft pad can transform the rigid contact between scraper 34 and the surface of heat exchanger 1 into a flexible contact, preventing scraper 34 from scratching the surface of heat exchange tube fins or scraping off the anti-corrosion coating on the fin surface.
