[0004] In the process of developing this application, the inventors discovered the following problems with the prior art:

[0005] The heat exchanger unit is connected to the air inlet pipe through the exhaust pipe, so that the impurities in the exhaust gas will be filtered by the filter frame. Most of the exhaust gas contains impurities. As the operation continues, these impurities will accumulate. This accumulation will have an adverse effect on the use of the unit. In a minor case, it may interfere with the normal operation of the unit. In a serious case, it may even cause the entire unit to be blocked.

[0006] Therefore, those skilled in the art have provided energy-saving low-resistance heat exchange units to solve the problems mentioned in the background art. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an energy-saving low-resistance heat exchanger unit. The disassembly mechanism can disassemble the filter frame when large impurities are generated, which is convenient to operate. The high-temperature flue gas generated in the combustion chamber can exchange heat with the heat exchange box to achieve energy saving.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An energy-saving low-resistance heat exchanger unit includes a main body of the device. A disassembly mechanism is provided on one side of the main body of the device. The disassembly mechanism includes a connecting pipe and a connecting block. Multiple limiting blocks are fixedly provided on one side of the connecting pipe. Multiple sliders are slidably provided inside the connecting block. A spring is fixedly provided on one side of each slider. A compression spring is fixedly provided inside each limiting block. Multiple fixing blocks are fixedly provided on the side of the connecting block near the main body of the device.

[0010] A combustion chamber is fixedly installed at the lower end of the main body of the device, and an air inlet pipe is fixedly installed at the front end of the combustion chamber. A heat exchange box is fixedly installed at the upper end of the main body of the device, and an exhaust pipe is fixedly installed at the upper end of the combustion chamber. A filter frame is slidably installed inside the connecting block. Multiple sliders are fixedly installed on the outside of the filter frame away from the main body of the device, with each pair facing the other. The connecting block is snapped into the inside of the connecting pipe. Multiple pressure sensors are fixedly installed inside the connecting block near the spring.

[0011] Furthermore, a sealing ring is fixedly installed inside the connecting block on the side near the main body of the device, and one side of each of the multiple springs is fixedly installed inside the connecting block on the side away from the sealing ring.

[0012] Furthermore, each of the multiple fixing blocks has a fixing groove on opposite sides, and the multiple fixing blocks are slidably disposed inside the multiple limiting blocks.

[0015] This utility model has the following beneficial effects:

[0016] 1. The energy-saving low-resistance heat exchanger unit proposed in this utility model, during use, high-temperature flue gas will be discharged through the filter frame, and impurities will continue to accumulate, causing the thrust of the flue gas on the filter frame to continuously increase, causing the filter frame to move towards the pressure sensor, and causing the spring to contract inside the connecting block. When the slider moves to contact the pressure sensor, the pressure sensor will sound an alarm. At this time, the filter frame needs to be disassembled. During disassembly, the connecting block is rotated by turning the handle, so that the fixing block rotates synchronously inside the limit block, completing the disassembly of the connecting block, thereby achieving quick connection and disassembly, facilitating maintenance and repair, effectively preventing blockage caused by impurity accumulation, and improving the reliability of the unit.

[0017] 2. The energy-saving low-resistance heat exchanger unit proposed in this utility model allows for the combustion of fuel in the combustion chamber when outside air flows into the combustion chamber through the air inlet pipe, generating high-temperature flue gas. This high-temperature flue gas is then introduced into the connecting pipe through the exhaust pipe. The exhaust pipe is wrapped around the outside of the heat exchange box, so that the high-temperature flue gas flowing inside the exhaust pipe can provide heating for the inside of the heat exchange box, thereby achieving efficient heat conversion, improving energy efficiency, and achieving the goal of energy conservation and emission reduction.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-8 One embodiment provided by this utility model:

[0030] An energy-saving low-resistance heat exchanger unit includes a main body 1. A disassembly mechanism 4 is provided on one side of the main body 1. The disassembly mechanism 4 includes a connecting pipe 401 and a connecting block 404. Multiple limiting blocks 407 are fixedly installed on one side of the connecting pipe 401. Multiple sliders 410 are slidably installed inside the connecting block 404. A spring 411 is fixedly installed on one side of each slider 410. Compression springs 413 are fixedly installed inside each limiting block 407. Multiple fixing blocks 405 are fixedly installed on the outside of the connecting block 404 near the main body 1. A sealing ring 409 is fixedly installed inside the connecting block 404 near the main body 1. One side of each spring 411 is fixedly installed inside the connecting block 404 away from the sealing ring 409. A filter frame 403 is slidably arranged. Multiple sliders 410 are fixedly arranged on the outside of the filter frame 403 away from the main body 1, with each pair of opposite sides. A connecting block 404 is externally snapped into the inside of the connecting tube 401. Multiple pressure sensors 408 are fixedly arranged on the inside of the connecting block 404 near the spring 411. Multiple fixing blocks 405 have fixing grooves 406 on opposite sides. Multiple fixing blocks 405 are slidably arranged inside multiple limiting blocks 407. Multiple compression springs 413 have limiting pins 412 fixedly arranged on opposite sides. Multiple limiting pins 412 are respectively arranged on opposite sides of multiple fixing grooves 406. A handle 402 is fixedly arranged on the side of the connecting block 404 away from the main body 1.

[0031] Specifically, during use, when high-temperature flue gas is discharged from the exhaust pipe 6, it first passes through the filter frame 403 to complete the filtration process of impurities. This causes impurities to gradually accumulate on one side of the filter frame 403. The accumulation of impurities will increase the pushing force of the flue gas on the filter frame 403, causing the filter frame 403 and the slider 410 to move towards the pressure sensor 408. As the slider 410 moves, it will compress the spring 411 connected to it, causing the spring 411 to gradually contract inside the connecting block 404. Once the slider 410 touches the pressure sensor 408, the sensor will immediately trigger an alarm signal. At this time, the air inlet pipe 2 should be closed immediately, and then the filter frame 403 should be disassembled. During disassembly, first rotate the connecting block 404 by the handle 402 to drive its rear end. The fixed block 405 rotates synchronously inside the limiting block 407. As the fixed block 405 rotates, the limiting pin 412 slides inside the limiting block 407 and squeezes the compression spring 413 connected to it, causing the compression spring 413 to contract inside the limiting block 407, so that the connecting block 404 can be removed from the connecting pipe 401. The disassembly mechanism 4 makes the connection between the connecting pipe 401 and the connecting block 404 both firm and easy to maintain. When the filter frame 403 needs to be replaced or cleaned, the operator can easily pull the connecting block 404 out of the connecting pipe 401 through the handle 402 without using additional tools, reducing maintenance costs and downtime. After the replacement is completed, the sealing ring 409 can effectively prevent leakage and ensure the normal operation of the heat exchange unit.

[0032] Reference Figures 1-8 A combustion chamber 5 is fixedly installed at the lower end of the main body 1 of the device. An air inlet pipe 2 is fixedly installed at the front end of the combustion chamber 5. A heat exchange box 7 is fixedly installed at the upper end of the main body 1 of the device. An exhaust pipe 6 is fixedly installed at the upper end of the combustion chamber 5. A heat exchange tube 3 is fixedly installed inside the heat exchange box 7. The output end of the exhaust pipe 6 is fixedly installed on the side of the connecting pipe 401 near the main body 1 of the device.

[0033] Specifically, when external air enters the combustion chamber 5 through the air inlet pipe 2, it provides oxygen for combustion. In the combustion chamber 5, fuel combustion produces high-temperature flue gas. The high-temperature flue gas enters the connecting pipe 401 through the exhaust pipe 6. When passing through the connecting pipe 401, the flue gas is first filtered by the filter frame 403 to remove impurities and reduce the emission of harmful substances, meeting strict environmental protection standards. Since the exhaust pipe 6 is wrapped around the outside of the heat exchange box 7, the high-temperature flue gas inside the exhaust pipe 6 will heat the heat exchange tubes 3 inside the heat exchange box 7, achieving efficient heat exchange, improving energy utilization, and achieving the purpose of energy saving.

[0034] Working Principle: During operation, external air enters the combustion chamber 5 through the air inlet pipe 2, generating high-temperature flue gas. This high-temperature flue gas then enters the connecting pipe 401 through the exhaust pipe 6. As the flue gas passes through the connecting pipe 401, the filter frame 403 inside the connecting pipe 401 filters the flue gas, removing impurities. Because the exhaust pipe 6 is wrapped around the outside of the heat exchange box 7, the high-temperature flue gas inside the exhaust pipe 6 can heat the inside of the heat exchange box 7, achieving efficient heat exchange and improving energy utilization. During filtration, impurities accumulate on one side of the filter frame 403, thereby increasing the thrust of the flue gas on the filter frame 403. The large size causes the slider 410 to move towards the pressure sensor 408. The movement of the slider 410 will compress the spring 411 connected to it, causing it to continuously contract inside the connecting block 404. When the pressure sensor 408 is contacted, it will sound an alarm. At this time, the air inlet pipe 2 will be closed. When disassembling the filter frame 403, first rotate the connecting block 404 by the handle 402 so that the fixing block 405 at the rear end rotates synchronously inside the limiting block 407. This causes the limiting pin 412 to slide inside the limiting block 407 and compress the compression spring 413 connected to it, causing it to contract inside the limiting block 407. Then, the connecting block 404 can be removed from the connecting pipe 401.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
