Description

Technical Field

[0001] This invention belongs to the field of air cooler technology, and particularly relates to an air cooler and its application in an integrated compressor. Background Technology

[0002] Commonly used air coolers mainly consist of a steel frame, heat pipes installed inside the frame, and a fan installed outside or on top of the frame. However, commonly used air coolers occupy a large space and are time-consuming and labor-intensive to install. Integrated compressors mainly consist of a housing, a built-in compressor, and an air cooler, with the air cooler located inside the housing cavity. However, this traditional structural arrangement suffers from at least two drawbacks: large footprint and high operating costs, especially since the air cooler typically occupies about half the total footprint of the integrated compressor. Summary of the Invention

[0003] This invention provides an air cooler and its application in an integrated compressor, which can at least solve the problems of large footprint and high operating cost of existing air coolers.

[0004] The technical solution adopted in this invention is as follows.

[0005] An air cooler includes heat exchange tubes and fans. It employs several parallel heat exchange tubes as the inner structure of the outer shell sidewall, and several spaced-apart fans are arranged outside the heat exchange tubes. The fans and heat exchange tubes together form the outer shell sidewall. To improve the air cooling effect, two outer shell sidewalls are arranged facing each other, one serving as the heat exchange medium inlet channel and the other as the heat exchange medium outlet channel. Using this technical solution, with the same heat exchange power, the air cooler of this invention occupies only about 40% of the space of a traditional steel frame-supported air cooler, significantly reducing the space required and installation difficulty.

[0006] The application of the air cooler in the integrated compressor in this invention is as follows.

[0007] The air cooler is applied to an integrated compressor and includes: a housing and a compressor body disposed within the housing, wherein an air outlet and an air inlet are respectively provided on both sides of the housing, and a high-pressure pipe and a low-pressure pipe are provided on the compressor body; the air cooler is disposed on the housing and includes a high-pressure heat exchange pipe and a low-pressure heat exchange pipe respectively coiled in the air outlet and the air inlet, wherein the high-pressure heat exchange pipe is connected between the high-pressure pipe and the low-pressure heat exchange pipe, and the low-pressure heat exchange pipe is connected between the high-pressure heat exchange pipe and the low-pressure pipe.

[0008] Preferably, the air cooler further includes a dustproof net 1 that can be detachably installed at the air inlet, and a dustproof net 2 and an insect-proof net that can be detachably installed at the air outlet. The insect-proof net is located outside the dustproof net 2. A plurality of fans and an isolation frame are provided between the dustproof net 2 and the insect-proof net. The plurality of fans are all located inside the isolation frame and are detachably connected to the inner side of the insect-proof net. The isolation frame is fixedly connected to the outer side of the dustproof net 2.

[0009] Preferably, four bearing seats are fixedly installed on the air inlet side of the outer casing. The four bearing seats are respectively grouped and located above and below the dustproof net. The same threaded rod is rotatably installed on two bearing seats in the group. A drive plate is threaded on both threaded rods. The same assembly frame is fixedly installed on the two drive plates. A cleaning plate is slidably installed in the assembly frame. The cleaning plate is correspondingly arranged with the dustproof net and the air inlet. A brush for cleaning the dustproof net is provided on one side of the cleaning plate.

[0010] Preferably, a motor is fixedly mounted on the housing, and pulleys are fixedly mounted on the output shaft of the motor and on the two threaded rods, with the same synchronous belt fitted onto the multiple pulleys.

[0011] Preferably, the cleaning plate has at least two positioning slots, the assembly frame has a cavity corresponding to the positioning slots, a positioning ball that can be embedded in the positioning slot is movably installed in the cavity, and a spring is fixedly installed in the cavity, the spring being fixedly connected to the positioning ball.

[0012] Preferably, a guide block is fixedly installed on the top of the sweeping plate, the guide block being flush with the side of the sweeping plate away from the brush, and a guide plate frame adapted to the guide block is fixedly installed on the outer shell.

[0013] Preferably, a guide block two is fixedly installed at the bottom of the cleaning plate, and a guide plate frame two adapted to the guide block two is fixedly installed on the outer shell. The guide plate frame two and the guide plate frame one are symmetrically arranged along the dustproof net one.

[0014] Preferably, the first guide block, the first guide plate frame, the second guide block, and the second guide plate frame all have inclined surfaces, and the inclined surfaces on the first guide block and the second guide block are opened in opposite directions.

Multiple dust suction covers are provided on the top of the air suction pipe. A fan is fixedly installed on the outer shell, and the air inlet of the fan is connected to the air suction pipe.

[0016] Preferably, the portions of the high-pressure heat exchange tube and the low-pressure heat exchange tube located inside the air outlet and air inlet are both coiled.

[0017] The present invention has the following beneficial effects: Under the same heat exchange power, the space occupied by the air cooler of the present invention is only about 40% of that of the traditional air cooler supported by a steel structure frame, which significantly reduces the space occupied by the air cooler and the difficulty of installation; This solution changes the structural layout of the traditional integrated compressor, reduces the overall size and lowers the operating cost, and opens air outlets and air inlets on both sides, and builds high-pressure heat exchange tubes and low-pressure heat exchange tubes to achieve heat exchange. Equipped with other components of the air cooler, it realizes air flow, which reduces the operating cost while ensuring heat dissipation. Attached Figure Description

[0036] The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings are used to distinguish different objects, not to describe a particular order.

[0037] This embodiment provides a specific solution for applying an air cooler to an integrated compressor, such as... Figure 1-17As shown, it includes: a housing 1 and a compressor body 2 disposed within the housing 1. The housing 1 has an air outlet 3 and an air inlet 4 on its two sides respectively. The compressor body 2 is provided with a high-pressure pipe 5 and a low-pressure pipe 6. An air cooler is disposed on the housing 1. The air cooler includes a high-pressure heat exchange pipe 7 and a low-pressure heat exchange pipe 8 respectively coiled in the air outlet 3 and the air inlet 4. The high-pressure heat exchange pipe 7 is connected between the high-pressure pipe 5 and the low-pressure heat exchange pipe 8. The low-pressure heat exchange pipe 8 is connected between the high-pressure heat exchange pipe 7 and the low-pressure pipe 6.

[0038] In this embodiment, the solution changes the traditional integrated compressor structure layout, reducing the overall size and lowering the operating cost. At the same time, air outlets 3 and air inlets 4 are opened on both sides, and high-pressure heat exchange tubes 7 and low-pressure heat exchange tubes 8 are built-in to achieve heat exchange. Other components of the air cooler are equipped to achieve air flow. While ensuring heat dissipation, the operating cost is reduced. During use, air enters through the air inlet 4 and carries away the heat on the low-pressure heat exchange tube 8, and then exits through the air outlet 3, while carrying away the heat on the high-pressure heat exchange tube 7. The overall heat dissipation effect is good.

[0039] In a further preferred embodiment of the present invention, the air cooler further includes a dustproof net 9 detachably installed at the inlet of the air inlet 4, and a dustproof net 10 and an insect-proof net 11 detachably installed at the outlet of the air outlet 3. The insect-proof net 11 is located outside the dustproof net 10. A plurality of fans 12 and an isolation frame 13 are provided between the dustproof net 10 and the insect-proof net 11. The plurality of fans 12 are all located inside the isolation frame 13. The plurality of fans 12 are detachably connected to the inner side of the insect-proof net 11. The isolation frame 13 is fixedly connected to the outer side of the dustproof net 10.

[0040] In this embodiment, when the air cooler is running, multiple fans 12 are powered on. The multiple small fans 12 can ensure the heat dissipation effect. The fans 12 generate suction, and the hot air inside the outer casing 1 is drawn out. The air entering from the other side is filtered through the dustproof net 9 and then discharged through the air outlet 3. The insect net 11 at the air outlet 3 can protect the fans 12. The dustproof net 10 can prevent backflow problems. The local wind direction is taken into account during assembly to reduce backflow problems.

[0041] In a further preferred embodiment of the present invention, four bearing seats 14 are fixedly installed on the air inlet side of the outer shell 1. The four bearing seats 14 are respectively grouped above and below the dustproof net 9. The same threaded rod 15 is rotatably installed on two bearing seats 14 in the group. A drive plate 16 is threadedly sleeved on both threaded rods 15. The same assembly frame 17 is fixedly installed on the two drive plates 16. A cleaning plate 18 is slidably installed in the assembly frame 17. The cleaning plate 18 is correspondingly arranged with the dustproof net 9 and the air inlet 4. A brush 19 for cleaning the dustproof net 9 is provided on one side of the cleaning plate 18.

[0042] In this embodiment, the drive plate 16 driven by the threaded rod 15 can drive the assembly frame 17 to move up and down. The assembly frame 17 drives the cleaning plate 18 to move. The brush 19 can clean the dust on the dust screen 9. The sliding cleaning plate 18 only contacts the brush 19 with the dust screen 9 when it reaches the top. It cleans the dust during the downward movement. After reaching the bottom, the brush 19 separates from the dust screen 9 and then moves up to reset. This process is repeated to prevent the brush 19 from still contacting the dust screen 9 when moving upward and to avoid the problem of brushing backward. This increases the usage frequency of the brush 19.

[0043] In a further preferred embodiment of the present invention, a motor 20 is fixedly installed on the outer casing 1, and pulleys 21 are fixedly installed on the output shaft of the motor 20 and on the two threaded rods 15, and the same synchronous belt 22 is sleeved on the multiple pulleys 21.

[0044] In this embodiment, the motor 20 is started during cleaning. The output shaft of the motor 20 drives the pulley 21 and the timing belt 22 to rotate, so that the two threaded rods 15 rotate synchronously, making cleaning less strenuous.

[0045] In a further preferred embodiment of the present invention, at least two positioning grooves 23 are provided on the cleaning plate 18, and a cavity 24 corresponding to the positioning grooves 23 is provided in the assembly frame 17. A positioning ball 25 that can be embedded in the positioning groove 23 is movably installed in the cavity 24, and a spring 26 is fixedly installed in the cavity 24. The spring 26 is fixedly connected to the positioning ball 25.

[0046] In this embodiment, the cleaning plate 18 is fixed to the assembly frame 17 by using a positioning ball 25 connected by a spring 26 and embedded in the positioning groove 23 for fixation. The overall fixing method is similar to that of telescopic poles and umbrellas in the prior art.

[0047] In a further preferred embodiment of the present invention, a guide block 27 is fixedly installed on the top of the sweeping plate 18, the guide block 27 is flush with the side of the sweeping plate 18 away from the brush 19, and a guide plate frame 28 adapted to the guide block 27 is fixedly installed on the outer shell 1.

[0048] In this embodiment, when the sweeping plate 18 moves upward, the inclined surface of the guide block 27 abuts against the inclined surface of the guide plate frame 28, causing the sweeping plate 18 to move towards the position of the dustproof net 9, so that the brush 19 contacts the dustproof net 9, ensuring that the dustproof net 9 can be cleaned when moving downward, and at the same time, the two positioning slots 23 are swapped.

[0049] In a further preferred embodiment of the present invention, a guide block 29 is fixedly installed at the bottom of the cleaning plate 18, and a guide plate frame 30 adapted to the guide block 29 is fixedly installed on the outer shell 1. The guide plate frame 30 and the guide plate frame 28 are symmetrically arranged along the dustproof net 9.

[0050] In this embodiment, when the sweeping plate 18 moves downward, the inclined surface of the guide block 29 abuts against the inclined surface of the guide plate frame 30, causing the sweeping plate 18 to move to the other side, so that the brush 19 separates from the dustproof net 9, thus avoiding damage to the brush 19 when moving upward.

[0051] In a further preferred embodiment of the present invention, the guide block 27, the guide plate frame 28, the guide block 29 and the guide plate frame 30 all have inclined surfaces, and the inclined surfaces on the guide block 27 and the guide block 29 are opened in opposite directions.

[0052] In a further preferred embodiment of the present invention, a support plate 31 fixedly connected to the outer shell 1 is provided below the dustproof net 9, an air suction pipe 32 is fixedly installed on the support plate 31, a plurality of dust suction covers 33 are provided on the top of the air suction pipe 32, a fan 34 is fixedly installed on the outer shell 1, and the air inlet end of the fan 34 is connected to the air suction pipe 32.

[0053] In this embodiment, the fan 34 can be started during cleaning, so that the dust suction hood 33 sucks in the dust, and then the dust is collected by the air suction pipe 32 and discharged by the fan 34. The air outlet of the fan 34 can be directed to the dust collection device.

[0054] In a further preferred embodiment of the present invention, the portions of the high-pressure heat exchange tube 7 and the low-pressure heat exchange tube 8 located within the air outlet 3 and the air inlet 4 are both coiled together.

[0055] This solution reduces the overall size of the compressor, decreasing the overall footprint by more than 40% compared to a traditional integrated compressor of the same power, thus lowering operating costs. The daily operating cost is reduced by approximately 35% compared to a traditional integrated compressor of the same power. Additionally, air outlets 3 and inlets 4 are located on both sides, and high-pressure heat exchange tubes 7 and low-pressure heat exchange tubes 8 are built-in to achieve heat exchange. Other components of the air cooler are also included to facilitate airflow, ensuring heat dissipation while reducing operating costs.
