Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, specifically to a high-efficiency microchannel refrigerant pump-driven heat exchange device. Background Technology

[0002] Heat exchange equipment is a device that transfers heat between two fluids, hot and cold, through solid walls or direct contact. It is widely used in refrigeration, HVAC, and chemical industries. By optimizing the structure to enhance heat exchange efficiency, it meets the process requirements of heating, cooling, condensation, and evaporation. It is a core device for energy utilization and thermal management. In order to improve the heat exchange effect of heat exchange equipment, a high-efficiency microchannel refrigerant pump-driven heat exchange equipment is needed.

[0003] High-efficiency microchannel refrigerant pump-driven heat exchange equipment relies on pump power to drive the refrigerant to circulate in a flat tube integrating a large number of microchannels, while the gas or liquid material to be heat exchanged flows through the gaps in the flat tube. The device achieves efficient heat exchange between the hot and cold fluids through the tube wall. With its microchannel structure, it enhances heat exchange efficiency and is widely used in the fields of refrigeration and thermal management. It also features a compact structure and excellent energy efficiency.

[0004] Currently available high-efficiency microchannel refrigerant pump-driven heat exchangers consist of flat tubes and manifolds. During use, they require manual disassembly and cleaning to prevent accumulated dust from clogging the gaps between the flat tubes. To improve cleaning convenience, existing technologies use the reciprocating motion of an electric brush to clean dust from the flat tube surface. To further enhance cleaning, existing technologies employ a cleaning block with a reciprocating threaded sleeve to scrape the dust along the flat tube. However, both methods require manual shutdown or external power supply or equipment for cleaning, and the cleaning continuity is insufficient during long-term, high-frequency use, affecting heat exchange efficiency and reducing the reliability of the device. Summary of the Invention

Multiple blades are fixedly connected to the outside of the rotating rods. A bevel gear is fixedly connected to the top of the outer side of the rotating rods. A bevel gear is rotatably connected to the top of the inner side of the flow guiding tube. The bevel gear and the bevel gear mesh with each other. Blades are fixedly connected to the outer side of the bevel gear through the flow guiding tube. A positioning component is provided on the outer side of the base.

[0009] Preferably, the buffer mechanism includes hollow plates, and multiple hollow plates are slidably connected to the upper and lower sides of the inside of the guide tube. A plug-in block is fixedly connected to the left side of the hollow plate. The inner side of the plug-in block engages with the flat tube. U-shaped blocks are fixedly connected to the front and rear sides of the plug-in block. A spring telescopic plate is rotatably connected to the inner side of the U-shaped block. Multiple spring telescopic rods are fixedly connected to the front and rear sides of the outer wall of the guide tube. The outer side of the spring telescopic rods passes through the guide tube and is rotatably connected to the spring telescopic plate. A support assembly is provided on the outside of the base.

[0010] Preferably, the circulation assembly includes water pumps, two of which are respectively connected to the bottom of the guide pipe, and a connecting pipe connects adjacent water pumps.

[0011] Preferably, the operating component includes a handle, and multiple handles are respectively disposed on the outer wall of the guide tube. Screws are threadedly connected to the upper and lower sides of the inside of the handle, and the handle is threadedly connected to the guide tube by the screws.

[0012] Preferably, the flow guiding assembly includes a flow guiding shroud, and a plurality of flow guiding shrouds are respectively fixedly connected to the front and rear sides of the outer side of the flow guiding pipe, and a flow guiding groove is formed on the inner side of the flow guiding shroud.

[0013] Preferably, the cleaning mechanism further includes guide rails, and multiple guide rails are respectively fixedly connected to the front and rear sides of the top of the corresponding guide pipe, and the cleaning brush is slidably connected to the guide rails.

[0014] Preferably, the positioning component includes positioning plates, two of which are fixedly connected to the front and rear sides of the base, and positioning holes are opened on both the left and right sides of the positioning plates.

[0015] Preferably, the support assembly includes connecting plates, and a plurality of connecting plates are fixedly connected to the outer perimeter of the base, with a bracket fixedly connected to the outer side of the connecting plates.

[0017] This invention provides a high-efficiency microchannel refrigerant pump-driven heat exchange device. It has the following beneficial effects:

[0018] 1. When using the device, the refrigerant circulates between the microchannels of the base, guide tube, and flat tube, exchanging heat with the material passing through the gap of the flat tube. The material flow drives the paddle to rotate, which in turn drives the reciprocating rod to rotate, which in turn drives the cleaning brush to move along the flat tube, automatically cleaning the outer impurities and dust. This process does not require additional power, which can prevent impurities from accumulating and clogging the gap of the flat tube after long-term use, avoiding affecting the heat exchange effect of the device, thereby improving the reliability of the device.

[0019] 2. The present invention also drives the three blades to rotate through the material flow, which in turn drives the two bevel gears on both sides to rotate. The bevel gear one meshing with it rotates accordingly, driving the rotating rod and the two blades to rotate. Through the rotation of the two blades, the flow and circulation of the refrigerant in the guide pipe can be improved, thereby improving the efficiency of the device.

[0020] 3. The invention does not affect the use of the rotating rod through the holes in the hollow plate. Moving the hollow plate can push the plug-in block to move, which can fix the flat tube when it is thermally expanded and contracted. The movement of the plug-in block drives the rotation of the spring telescopic plate through the U-shaped block, which causes the spring telescopic rod to extend and retract. The thrust generated by its elastic potential energy reinforces the flat tube. With the help of the sealing ring, it can maintain a seal when the flat tube moves due to thermal expansion and contraction. It can adjust the impact and damage caused by thermal expansion and contraction on the device according to the material temperature, thereby improving the practicality of the device.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1 , Figure 4 and Figure 6 This invention provides a high-efficiency microchannel refrigerant pump-propellant heat exchange device, including a base 1. The top left and right sides of the base 1 are connected to guide pipes 5. Multiple flat pipes 6 are arranged between adjacent guide pipes 5. Multiple microchannels 7 are opened on the inner side of the flat pipes 6. A cleaning mechanism 2 is arranged on the outer side of the flat pipes 6. The cleaning mechanism 2 is used for self-cleaning of the device. A guide mechanism 3 is arranged on the inner side of the guide pipes 5. The guide mechanism 3 can improve the circulation effect of the refrigerant. A buffer mechanism 4 is arranged inside the guide pipes 5. The buffer mechanism 4 can reduce the damage to the device caused by thermal expansion and contraction.

[0032] The cleaning mechanism 2 includes a fixing block 21, and multiple fixing blocks 21 are respectively fixedly connected to the outer periphery of the corresponding flat tube 6. A reciprocating rod 22 is rotatably connected to the inner side of the fixing block 21. Paddles 23 are fixedly connected to the left and right sides of the reciprocating rod 22. As the material flows, the paddles 23 and the reciprocating rod 22 can rotate. A cleaning brush 24 is threadedly connected to the outer side of the reciprocating rod 22. The rotation of the reciprocating rod 22 can drive the cleaning brush 24 to move and clean the flat tube 6. A sealing ring 25 is slidably connected to the left and right sides of the flat tube 6. The sealing ring 25 is connected to the guide tube 5. The sealing ring 25 can improve the sealing effect between the guide tube 5 and the flat tube 6. A circulation component 26 is provided inside the base 1. An operation component 27 is provided outside the guide tube 5. A guide component 28 is provided on the outer wall of the guide tube 5.

[0033] Specifically, when using the device, the refrigerant circulates between the base 1, the guide tube 5, and the microchannels 7 of the flat tubes 6, achieving heat exchange with the material passing through the gaps between the multiple flat tubes 6. At this time, the flow of the material will drive the paddle 23 to rotate, which in turn drives the reciprocating rod 22 to rotate synchronously. When the reciprocating rod 22 rotates, it will drive the cleaning brush 24 to move along the flat tubes 6, automatically cleaning the impurities and dust attached to the outside of the flat tubes 6. No additional power is required, and it can also prevent the accumulation of impurities and blockage of the gaps between the flat tubes 6 as the usage time increases, ensuring that the heat exchange effect of the device is not affected.

[0034] Reference Figure 2 , Figure 5 and Figure 7 The flow guiding mechanism 3 includes a rotating rod 31. Two rotating rods 31 are rotatably connected to the middle of the inner side of the flow guiding pipe 5. Multiple blades 32 are fixedly connected to the outside of the rotating rod 31. As the rotating rod 31 rotates, it can drive the blades 32 to rotate inside the flow guiding pipe 5. A bevel gear 33 is fixedly connected to the top of the outer side of the rotating rod 31. A bevel gear 34 is rotatably connected to the top of the inner side of the flow guiding pipe 5. The bevel gear 33 and the bevel gear 34 are meshed. When the rotating rod 31 rotates, it will drive the bevel gear 33 to rotate. As the bevel gear 33 rotates, it will drive the bevel gear 34 to rotate. A blade 35 is fixedly connected to the outside of the bevel gear 34 through the flow guiding pipe 5. As the blade 35 rotates, it can drive the bevel gear 34 to rotate. A positioning component 36 is provided on the outside of the base 1.

[0035] Specifically, the material flow will also drive the blade 35 to rotate. The rotation of the blade 35 will drive the bevel gear 2 34 on both sides to rotate. When the bevel gear 2 34 rotates, it will drive the bevel gear 1 33 meshing with it to rotate synchronously, which will cause the rotating rod 31 and the blade 2 32 on the rod to rotate accordingly. Through the rotation of the blade 2 32, the flow and circulation effect of the refrigerant in the guide pipe 5 can be enhanced.

[0036] Reference Figure 3 , Figure 5 and Figure 8 The buffer mechanism 4 includes a hollow plate 41. Multiple hollow plates 41 are slidably connected to the upper and lower sides of the inside of the guide tube 5. The hollow plates 41 can move left and right along the inside of the guide tube 5. A plug-in block 44 is fixedly connected to the left side of the hollow plate 41. The inner side of the plug-in block 44 engages with the flat tube 6. The engagement of the plug-in block 44 with the flat tube 6 can fix it to the flat tube 6. U-shaped blocks 45 are fixedly connected to the front and rear sides of the plug-in block 44. A spring telescopic plate 43 is rotatably connected to the inner side of the U-shaped block 45. The rotation and extension of the spring telescopic plate 43 can move the plug-in block 44 by pushing the U-shaped block 45. Multiple spring telescopic rods 42 are fixedly connected to the front and rear sides of the outer wall of the guide tube 5. The outer side of the spring telescopic rod 42 passes through the guide tube 5 and is rotatably connected to the spring telescopic plate 43. The extension and retraction of the spring telescopic plate 43 can push the spring telescopic plate 43. A support component 47 is provided on the outside of the base 1.

[0037] Specifically, the holes on the hollow plate 41 ensure that they do not affect the normal use of the rotating rod 31. Moving the hollow plate 41 can push the plug block 44 to move, so as to meet the fixing requirements of the flat tube 6 under the condition of thermal expansion and contraction. When the plug block 44 moves, it will drive the spring telescopic plate 43 to rotate through the U-shaped block 45. During the rotation and extension of the spring telescopic plate 43, it will push the spring telescopic rod 42 to extend and retract. The thrust generated by the elastic potential energy of the spring telescopic rod 42 will further reinforce the flat tube 6. At the same time, with the cooperation of the sealing ring 25, the flat tube 6 can always maintain a sealed state when it moves due to thermal expansion and contraction.

[0038] Reference Figure 3 , Figure 5 and Figure 7 The circulation component 26 includes a water pump 261, with two water pumps 261 respectively connected to the bottom of the guide pipe 5. Each of the two adjacent water pumps 261 is connected to a connecting pipe 262. By starting the water pumps 261 in conjunction with the connecting pipes 262, the refrigerant can be circulated within the device. The operation component 27 includes a handle 271, with multiple handles 271 respectively disposed on the outer wall of the guide pipe 5. The upper and lower sides of the inside of the handle 271 are threaded with screws 272. The handle 271 is threaded to the guide pipe 5 through the screws 272. The screws 272 can fix the handle 271, and the device can be fixed by holding the handle 271.

[0039] Specifically, by starting the water pump 261, materials can be drawn out or injected from the guide pipe 5, and simultaneously discharged or drawn into the connecting pipe 262, thereby circulating the refrigerant between the water pump 261, the connecting pipe 262, the guide pipe 5, and the microchannel 7. By holding the handle 271 fixed by the screw 272, it is easy to transport and operate the device for installation. At the same time, by releasing the screw 272, the handle 271 can be disassembled and installed as needed.

[0040] Reference Figure 1 , Figure 2 and Figure 6 The flow guiding assembly 28 includes a flow guiding cover 281, and multiple flow guiding covers 281 are respectively fixedly connected to the front and rear sides of the outer side of the flow guiding pipe 5. The inner side of the flow guiding cover 281 is provided with a flow guiding groove 282. Through the flow guiding of the flow guiding groove 282, the flow direction of the material can be adjusted to drive the paddle 23. The cleaning mechanism 2 also includes a guide rail 29, and multiple guide rails 29 are respectively fixedly connected to the front and rear sides of the top of the corresponding flow guiding pipe 5. The cleaning brush 24 is slidably connected to the guide rail 29. The cleaning brush 24 can move along the guide rail 29 to improve the stability during movement.

[0041] Specifically, the guide groove 282 inside the guide cover 281 allows the material to fully contact the blade 23 during flow, so as to push the blade 23. By sliding with the guide rail 29, the stability of the cleaning brush 24 during movement can be improved.

[0042] Reference Figure 3 , Figure 5 and Figure 8 The positioning component 36 includes a positioning plate 361, with two positioning plates 361 fixedly connected to the front and rear sides of the base 1. Positioning holes 362 are opened on both the left and right sides of the positioning plate 361. Threaded parts can be inserted into the positioning holes 362 to facilitate fixing the device. The support component 47 includes a connecting plate 472, with multiple connecting plates 472 fixedly connected to the outer periphery of the base 1. A bracket 471 is fixedly connected to the outer side of the connecting plate 472, providing support for the device through the bracket 471 and the connecting plate 472. The buffer mechanism 4 also includes a pull rod 46, with multiple pull rods 46 slidably connected to the upper and lower sides of the guide tube 5. The outer side of the pull rod 46 passes through the guide tube 5 and is fixedly connected to the hollow plate 41. Moving the pull rod 46 allows adjustment of the hollow plate 41 to adjust the buffering effect.

[0043] Specifically, by inserting threaded parts into the positioning holes 362 on both sides of the positioning plate 361, the device can be easily installed and fixed. The device can be supported and fixed by the connecting plate 472 and the bracket 471 fixed on it. At the same time, by operating the pull rod 46 to extend and retract, the hollow plate 41 can be easily operated and pushed to move.

[0044] Working principle: When using the device, the refrigerant circulates between the microchannels 7 in the base 1, the guide tube 5, and the flat tube 6, exchanging heat with the material passing through the gaps between the multiple flat tubes 6. The flow of the material drives the paddle 23 to rotate. As the paddle 23 rotates, the reciprocating rod 22 rotates accordingly. As the reciprocating rod 22 rotates, the cleaning brush 24 moves along the flat tube 6, cleaning the impurities and dust attached to the outside of the flat tube 6 automatically. No additional power is required, and it can prevent the accumulation of impurities and blockage of the gaps between the multiple flat tubes 6 over time, thus affecting the heat exchange effect of the device.

[0045] Furthermore, as the material flows, it will also drive the blade 35 to rotate. At this time, the rotation of the blade 35 will drive the bevel gear 2 34 on both sides to rotate. The rotation of the bevel gear 2 34 will drive the bevel gear 1 33 meshing with it. And the rotation of the bevel gear 1 33 will drive the rotating rod 31 and the blade 2 32 on it to rotate. In this way, the rotation of the blade 2 32 will improve the flow and circulation of the refrigerant in the guide pipe 5.

[0046] Finally, the holes in the hollow plate 41 ensure that it does not affect the use of the rotating rod 31. Moving the hollow plate 41 can push the plug block 44 to move, adapting to the fixation of the flat tube 6 during thermal expansion and contraction. At the same time, when the plug block 44 moves, it will drive the spring telescopic plate 43 to rotate through the U-shaped block 45. At this time, the rotation and extension of the spring telescopic plate 43 can push the spring telescopic rod 42 to extend and retract. In this way, the thrust adjusted by the elastic potential energy of the spring telescopic rod 42 further fixes the flat tube 6. At the same time, the sealing ring 25 can seal the flat tube 6 when it moves due to thermal expansion and contraction.
