Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a heat exchanger that is easy to disassemble. Background Technology

[0002] In the renovation of old urban areas, the original heating system may have problems such as aging and low efficiency. By installing heat exchange units, the existing heating system can be optimized and upgraded. Moreover, in the construction of new urban planning areas, such as industrial parks and commercial centers, heat exchange units have become an important part of the heating system design to meet the special energy supply requirements of these areas.

[0003] In existing devices, heat is mainly transferred through heat exchangers. Heat exchangers are usually composed of multiple sets of heat exchange plates and rubber gaskets stacked alternately. By transferring liquids of different temperatures to the adjacent heat exchange plates, heat can be transferred from the high-temperature liquid to the low-temperature liquid through the temperature difference of the liquid, thus completing the heat exchange. Because the rubber gaskets may age after the heat exchange plates have been working for a long time, the staff needs to disassemble the heat exchange plates and rubber gaskets for replacement and maintenance every once in a while.

[0004] However, in order to ensure that the heat exchange fins do not leak during operation, the heat exchange fins and rubber gaskets are usually squeezed and fixed by multiple sets of screws and nuts. This means that the workers need to tighten multiple sets of nuts one by one to disassemble the entire heat exchanger, which makes the disassembly process more troublesome and labor-intensive. Moreover, the use of tools to remove the nuts during the disassembly process may also damage the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a heat exchanger unit that is easy to disassemble, so as to solve the problem of difficult disassembly of heat exchanger plates mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat exchanger unit that is easy to disassemble includes: a main body with a guide rod on it, a fixing plate on the guide rod, and heat exchange fins on the fixing plate; a disassembly assembly on the guide rod, including a sliding plate on the guide rod, a connecting plate on the sliding plate, a lead screw on the connecting plate, and a fixing block on the lead screw; the disassembly assembly is used for quick disassembly of the heat exchange fins; and a fixing assembly on the fixing plate, including a torsion spring on the fixing plate, a connecting rod on the torsion spring, and a locking block on the connecting rod; the fixing assembly is used for fixing the fixing block.

[0008] Preferably, the disassembly assembly further includes two sets of rotating shafts symmetrically arranged on both sides of the sliding plate, with a connecting plate fixedly connected to the outside of the rotating shafts, and a lead screw threadedly connected to the end of the connecting plate away from the rotating shaft.

[0009] Preferably, a mounting plate is rotatably connected to one side of the lead screw, and a handle is fixedly connected to the other side of the lead screw.

[0010] Preferably, two sets of T-shaped blocks are symmetrically fixedly connected on the side of the mounting plate near the connecting plate, and T-shaped grooves are provided on the connecting plate corresponding to the T-shaped blocks, with the T-shaped blocks movably disposed in the T-shaped grooves.

[0011] Preferably, a fixing block is fixedly connected to the side of the mounting plate near the fixing plate, and a fixing groove is provided on the fixing plate corresponding to the fixing block, with the fixing block and the fixing groove matching.

[0012] Preferably, the fixing assembly further includes connectors symmetrically arranged on both sides of the fixing plate, a rotating cylinder is rotatably connected to the connector, the rotating cylinder passes through the connector, and a connecting rod is fixedly connected to the outer side of the rotating cylinder.

[0013] Preferably, a torsion spring is provided between the connecting rod and the connecting member, and the torsion spring is located on the outside of the rotating cylinder.

[0014] Preferably, the mounting plate has a corresponding card slot for the card block, and the card slot matches the card block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When it is necessary to disassemble the heat exchanger, the rotation of the control screw can drive the fixing block to slide out of the fixing groove, so that the sliding plate no longer squeezes and fixes the heat exchanger, which makes it easier for the staff to disassemble the heat exchanger and can effectively reduce the workload of the staff, thus achieving the effect of easy disassembly of the heat exchanger. At the same time, the setting of two sets of connecting plates can protect the heat exchanger that is in operation.

[0017] When the heat exchanger fins need to be installed, the fixing block is controlled to snap into the fixing groove. In order to prevent the fixing block from accidentally detaching from the fixing groove, the elastic force of the torsion spring is controlled to drive the locking block to be firmly locked in the groove, thereby fixing the fixing block.

Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1 - Figure 5 As shown, this application provides a heat exchanger unit that is easy to disassemble, including: a device body 1, a guide rod 3 on the device body 1, a fixing plate 6 on the guide rod 3, and heat exchange plates 2 on the fixing plate 6; and further including: a disassembly assembly on the guide rod 3, the disassembly assembly including a sliding plate 5 on the guide rod 3, a connecting plate 4 on the sliding plate 5, a lead screw 19 on the connecting plate 4, and a fixing block 16 on the lead screw 19. The disassembly assembly is used for quick disassembly of the heat exchange plates 2.

[0027] Specifically, such as Figure 5 As shown, the disassembly assembly also includes two sets of rotating shafts 14 symmetrically arranged on both sides of the sliding plate 5. A connecting plate 4 is fixedly connected to the outside of the rotating shaft 14. A lead screw 19 is threadedly connected to one end of the connecting plate 4 away from the rotating shaft 14. The connection plate 4 facilitates the complete wrapping of the heat exchange plate 2.

[0028] Specifically, such as Figure 5As shown, a mounting plate 8 is rotatably connected to one side of the lead screw 19, and a handle 20 is fixedly connected to one side of the lead screw 19. By rotating the handle 20, it is easy to achieve the effect of driving the lead screw 19 to rotate stably.

[0029] Specifically, such as Figure 5 As shown, two sets of T-shaped blocks 15 are symmetrically fixedly connected to the side of the mounting plate 8 near the connecting plate 4. The connecting plate 4 is provided with T-shaped grooves 18 corresponding to the T-shaped blocks 15. The T-shaped blocks 15 are movably disposed in the T-shaped grooves 18. Through the cooperation of the T-shaped blocks 15 and the T-shaped grooves 18, the movement direction of the mounting plate 8 can be limited.

[0030] Specifically, such as Figure 4 As shown, a fixing block 16 is fixedly connected to the side of the mounting plate 8 near the fixing plate 6. A fixing groove 17 is provided on the fixing plate 6 corresponding to the fixing block 16. The fixing block 16 and the fixing groove 17 match each other. Through the cooperation of the fixing block 16 and the fixing groove 17, the heat exchange plate 2 can be fixed.

[0031] A fixing component is provided on the fixing plate 6. The fixing component includes a torsion spring 11 provided on the fixing plate 6, a connecting rod 13 provided on the torsion spring 11, and a locking block 12 provided on the connecting rod 13. The fixing component is used to fix the fixing block 16.

[0032] Specifically, such as Figure 3 As shown, the fixing assembly also includes connectors 10 symmetrically arranged on both sides of the fixing plate 6. A rotating cylinder 7 is rotatably connected to the connector 10 and passes through the connector 10. A connecting rod 13 is fixedly connected to the outer side of the rotating cylinder 7. The arrangement of the rotating cylinder 7 facilitates the connection of the connecting rod 13 to the fixing plate 6.

[0033] Specifically, such as Figure 3 As shown, a torsion spring 11 is provided between the connecting rod 13 and the connecting piece 10. The torsion spring 11 is located on the outside of the rotating cylinder 7. Through the elastic force of the torsion spring 11, the connecting rod 13 can be driven to maintain a state of rotation towards the mounting plate 8.

[0034] Specifically, such as Figure 3 As shown, the mounting plate 8 is provided with a slot 9 corresponding to the card block 12. The slot 9 matches the card block 12. Through the cooperation of the slot 9 and the card block 12, the mounting plate 8 can be fixed.

[0035] In this embodiment: by controlling the rotation of the control handle 20, the lead screw 19 can be rotated, thereby driving the fixing block 16 to slide out of the fixing groove 17, so that the sliding plate 5 no longer squeezes and fixes the heat exchange plate 2, thus facilitating the disassembly of the heat exchange plate 2 by the operator. The two sets of connecting plates 4 can protect the working heat exchange plate 2. When it is necessary to install the heat exchange plate 2, the fixing block 16 is controlled to be inserted into the fixing groove 17. In order to prevent the fixing block 16 from accidentally disengaging from the fixing groove 17, the elastic force of the torsion spring 11 can be controlled to drive the locking block 12 to be firmly locked in the locking groove 9, thereby fixing the fixing block 16.

[0036] Specifically, when the heat exchanger 2 needs to be disassembled, since the fixing block 16 is initially stuck in the fixing groove 17, the control handle 20 is rotated, which drives the lead screw 19 to rotate, thereby moving the mounting plate 8. This allows the T-shaped block 15 to slide inside the T-shaped groove 18. Through the movement of the mounting plate 8, the fixing block 16 can be quickly disengaged from the fixing groove 17. At this time, the sliding plate 5 no longer squeezes the heat exchanger 2, making it easier for the staff to disassemble the heat exchanger 2. When the heat exchanger 2 is reinstalled, the control handle 20 is rotated in the opposite direction, causing the fixing block 16 to be re-clamped into the fixing groove 17, thus fixing the heat exchanger 2. To prevent the handle 20 from rotating accidentally and causing the heat exchanger 2 to loosen, the spring force of the torsion spring 11 can drive the connecting rod 13 to rotate, thereby keeping the locking block 12 firmly clamped in the locking groove 9. This allows the fixing block 16 to be firmly clamped inside the fixing groove 17, achieving another layer of fixation for the heat exchanger 2.

[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in detail for the sake of brevity.
