Description

Technical Field

[0001] The present invention belongs to the technical field related to compressors, and more specifically, it is a heat dissipation and noise reduction structure for a refrigeration compressor. Background Art

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system. It sucks in refrigerant gas at low temperature and low pressure from the suction pipe, compresses it by driving a piston through the operation of an electric motor, and then discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.

[0003] The patent document with the patent number CN108561290A discloses a shock absorption and noise reduction device for an automotive air-conditioning compressor, including a compressor main body, an in-vehicle cross beam, and a compressor housing. The compressor main body is placed inside the compressor housing. The bottom end of the compressor main body is fixed with a support by welding. The bottom end of the support is fixed with a welding seat by welding. A fixing seat is inserted at the bottom end of the welding seat. A shock absorption plate is arranged at the bottom end of the fixing seat. The bottom end of the shock absorption plate is fixed with a mounting seat. By setting structures such as a welding seat, a fixing seat, a shock absorption plate, a compression spring, a mounting seat, and an elastic base, the function of shock absorption is realized. The structure is simple, and the applicability is strong. The shock absorption effect is significantly improved. By setting structures such as a sponge and a speaker, the function of noise reduction is realized, and the noise reduction effect is significantly improved.

[0004] The above noise reduction structure uses a spring shock absorption method to reduce the noise of the compressor. When the compressor is running, there will be cylinder noise, crank rocker noise, and valve noise. The compressor itself is a noise source. The above device uses an elastic shock absorption method, which can only reduce the noise generated during the vibration between the compressor and the equipment, and resonance noise, but cannot eliminate the noise generated during the operation of the compressor itself. The noise reduction effect is poor. Secondly, when the refrigeration compressor is running, its surface temperature can reach 95°. If the shielding method is used to isolate and reduce the noise of the compressor, the compressor cannot perform normal heat dissipation operations, resulting in the compressor being in a high-temperature state for a long time, reducing its service life, and it does not have a noise reduction and heat dissipation structure. At the same time, the above noise reduction structure cannot be installed on compressors of different specifications. The fixing structures of different models of compressors are different, and the heat dissipation and noise reduction structure cannot be adjusted arbitrarily according to the compressor fixing structure, reducing the scope of application. Summary of the Invention

[0005] The purpose of the present invention is to provide a heat dissipation and noise reduction structure for a refrigeration compressor, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. When the compressor is running, there will be cylinder noise, crank rocker noise and valve noise. The compressor itself is the noise source. The above-mentioned device uses the elastic shock absorption method, which can only reduce the noise generated during the vibration between the compressor and the equipment and the resonance noise, but cannot eliminate the noise generated during the operation of the compressor itself, and the noise reduction effect is poor.

[0008] 2. When the refrigeration compressor is running, its surface can reach 95°. If the shielding method is used to isolate and reduce the noise of the compressor, the compressor cannot perform normal heat dissipation operations, resulting in the compressor being in a high temperature state for a long time, reducing its service life, and it does not have a noise reduction and heat dissipation structure.

[0009] 3. The above-mentioned noise reduction structure cannot be installed on compressors of different specifications. The fixed structures of compressors of different models are different, and the heat dissipation and noise reduction structure cannot be adjusted arbitrarily according to the fixed structure of the compressor, reducing the scope of application.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] A heat dissipation and noise reduction structure for a refrigeration compressor, including an inner sleeve box and an outer sleeve box. The inner sleeve box is fixedly installed in the middle position inside the outer sleeve box. There is a sound insulation groove in a zigzag structure between the inner sleeve box and the outer sleeve box. A gas inlet pipe is fixedly installed in the middle position on the outer surface of one end of the inner sleeve box, and an exhaust pipe is fixedly installed on the outer surface of the other end of the inner sleeve box. Both the gas inlet pipe and the exhaust pipe pass through both ends of the outer sleeve box. The inner sleeve box is combined and fixed by several groups of splicing card boards. The inside of the splicing card board is a hollow structure. A water collecting tray is movably installed at the upper ends of the inner sleeve box and the outer sleeve box. A fixed bottom plate is arranged at the lower end of the inner sleeve box. The inner sleeve box and the fixed bottom plate are elastically connected by springs. The lower end of the inner sleeve box and the outer sleeve box are butt-jointed and fixed by a fixing frame.

[0012] As a further technical solution of the present invention, a second fan is fixedly installed on the outer surface of one end of the exhaust pipe, and a first fan is fixedly installed on the outer surface of one end of the gas inlet pipe. A wire pipe groove for threading wires is provided in the middle of the front end of the inner sleeve box. The user places the refrigeration compressor inside the inner sleeve box. The outer sleeve box and the inner sleeve box are used to form a double sound insulation structure. At the same time, the inner sleeve box and the outer sleeve box are provided with a sound insulation groove in a zigzag structure to improve the sound insulation effect between the outer sleeve box and the inner sleeve box. At the same time, the first fan and the second fan are respectively the intake and exhaust fans. When the first fan and the second fan are running, external air enters the inside of the inner sleeve box through the gas inlet pipe to cool the compressor inside the inner sleeve box. At the same time, the second fan is used in cooperation with the exhaust pipe to extract the air, so that a high-speed cooling structure is formed inside the inner sleeve box to avoid heat accumulation.

[0013] As a further technical solution of the present invention, two groups of fixing buckles are fixedly installed on both sides of the fixed bottom plate. An elevating sleeve rod used in cooperation with a spring is movably installed at the upper end of the fixed bottom plate. By setting the spring and using the elevating sleeve rod in cooperation, an elastic buffer structure is formed between the outer casing and the fixed bottom plate, avoiding direct hard connection between the outer casing and the equipment. When the compressor in the inner casing operates, the vibration between the compressor and the equipment can be effectively reduced, playing a role in shock absorption and noise reduction.

[0014] As a further technical solution of the present invention, a cover plate is fixedly installed on the outer surface of the side of the splicing card plate. A wire pipe sleeve is fixedly installed at the middle position inside the splicing card plate. A fixed partition strip is provided between the wire pipe sleeve and the splicing card plate. The wire pipe sleeve and the fixed partition strip form a cross-shaped heat insulation structure inside the splicing card plate. By setting the wire pipe sleeve, the installation operation of the wire pipe for the compressor installed in the inner casing can be carried out. Secondly, the cross-shaped heat insulation structure formed by the wire pipe sleeve and the fixed partition strip can improve the structural strength of the splicing card plate while keeping the splicing card plate in good heat insulation effect.

[0015] As a further technical solution of the present invention, the two ends of the splicing card plate are spliced and fixed through docking inserts, and slots for cooperating with the docking inserts are provided at both ends of the splicing card plate. By using the docking inserts and the card slots in cooperation, multiple splicing card plates can be spliced and fixed, making the disassembly and assembly operation of the inner casing more convenient.

[0016] As a further technical solution of the present invention, the water collecting tray and the outer casing are movably docked through a fixed sleeve rod. A heat conducting pad is fixedly installed on the outer surface of the lower end of the water collecting tray, and the bottom of the heat conducting pad is in an arc shape. The fixed sleeve rod enables the accurate docking of the water collecting tray and the outer casing. The function of the water collecting tray is to collect the water discharged from the refrigerator, and heat conduction is carried out between the water collecting tray and the compressor through the heat conducting pad, so that the water in the water collecting tray can be used to cool the compressor.

[0017] As a further technical solution of the present invention, a side cover is fixedly installed on the outer surface of one side of the fixed card cover. A rectangular sleeve is provided on the outer surface of the other side of the fixed card cover. When the refrigeration compressor is installed and used, the pipelines and wire bodies need to be docked. The functions of the inner casing and the outer casing are to cool the compressor in a shielding manner. By installing the fixed card cover, the installation operation of the wire pipe for the compressor in the inner casing can be carried out without reducing the sound insulation effect of the inner casing and the outer casing.

[0018] As a further technical solution of the present invention, an end cover is fixedly installed on the outer surface of one end of the fixed card cover, and a card slot is opened in the middle of the end cover. The wire pipe passes through one end of the fixed card cover, and by covering the end cover, the wire pipe passes through the card slot of the end cover. The end cover can be used to improve the sealing effect of the fixed card cover.

[0019] As a further technical solution of the present invention, a first sliding bar and a second sliding bar are movably installed inside the upper end of the fixing frame. A sliding cap for fixing the compressor is movably installed inside the first sliding bar and the second sliding bar. By using the first sliding bar and the second sliding bar in cooperation with the sliding cap, it can be arbitrarily adjusted according to the fixing hole position of the compressor. At the same time, the lower part of the fixing frame adopts a hollow structure design to reduce the contact between the fixing frame and the outer casing.

[0020] As a further technical solution of the present invention, fastening bolts are installed at the ends of the first sliding bar, the second sliding bar and the sliding cap, and docking sliding grooves for cooperating with the fastening bolts are provided on the sides of the first sliding bar, the second sliding bar and the fixing frame.

[0021] Advantages of the present invention:

[0022] 1. By providing an inner casing and an outer casing, when the heat dissipation and noise reduction structure for the refrigeration compressor is in use, the refrigeration compressor is installed inside the inner casing. By using the zigzag sound insulation structure between the inner casing and the outer casing, double sound insulation operation is carried out on the refrigeration compressor. At the same time, in cooperation with several groups of springs on the fixed bottom plate, the noise generated during the operation of the compressor can be effectively reduced. During operation, the user places the refrigeration compressor inside the inner casing, and the outer casing cooperates with the inner casing to form a double sound insulation structure. At the same time, the inner casing and the outer casing are provided with sound insulation grooves in a zigzag structure, which can effectively shield the noise generated during the operation of the compressor inside the inner casing and the outer casing. Secondly, the inner casing is composed of multiple spliced card boards, and the spliced card boards adopt a hollow structure design, which improves the sound insulation effect of the inner casing. By setting the wire pipe sleeve, the installation of the wire pipe for the compressor installed inside the inner casing can be carried out. Secondly, the cross-shaped heat insulation structure formed by the wire pipe sleeve and the fixed partition strip in the spliced card board can improve the structural strength of the spliced card board while keeping the spliced card board in good heat insulation effect. At the same time, in order to enable the compressor to be used normally inside the inner casing and the outer casing, the installation of the wire pipe inside the inner casing and the outer casing is satisfied by installing a fixed card cover. By installing the fixed card cover, the wire pipe can be bent at a right angle and extend from one end of the fixed card cover. By covering the end cover, the wire pipe passes through the card slot of the end cover. The end cover can improve the sealing effect of the fixed card cover and install the wire pipe for the compressor inside the inner casing without reducing the sound insulation effect of the inner casing and the outer casing. By providing the inner casing and the outer casing, the compressor can be sound-insulated by a double shielding method, thereby reducing the noise generated during the operation of the compressor.

[0023] 2. By setting the first fan and the second fan, when the heat dissipation and noise reduction structure for the refrigeration compressor is in use, the first fan and the second fan can be used to optimize the use of the inner box and the outer box, enabling the two ends of the inner box and the outer box to have active air intake and exhaust structures respectively, accelerating the air flow inside the inner box, and enhancing the heat dissipation and cooling effect of the compressor. During operation, since the first fan and the second fan are respectively the intake and exhaust fans, when the first fan and the second fan operate, external air enters the interior of the inner box through the intake pipe to cool the compressor inside the inner box. At the same time, the second fan is used in conjunction with the exhaust pipe to extract the air, forming a high-speed air-cooling structure inside the inner box to avoid heat accumulation. Thus, while not affecting the use of the inner box and the outer box, the compressor can be kept in a stable state. Secondly, by setting the water collecting tray, when the compressor is installed in the refrigerator, the water collecting tray can collect the water discharged during the daily use of the refrigerator. Through water-cooling the compressor, the role of the water collecting tray is to collect the water discharged from the refrigerator. Heat conduction is carried out between the water collecting tray and the compressor through the heat conduction pad to enhance the heat conduction effect between the water collecting tray and the compressor. Thus, the water in the water collecting tray can be used to cool the compressor. In combination with the use of the first fan and the second fan, the refrigeration compressor has a dual cooling structure, enhancing the compressor cooling effect of the heat dissipation and noise reduction structure.

[0024] 3. By setting the second slide bar, the first slide bar and the sliding cap, when the heat dissipation and noise reduction structure for the refrigeration compressor is in use, the second slide bar, the first slide bar and the sliding cap can be used to optimize the installation and use of the entire heat dissipation and noise reduction structure, enabling the heat dissipation and noise reduction structure to be applicable to compressors of different specifications. The user can adjust the positions of the second slide bar and the first slide bar according to the compressor fixing structure, and then move the sliding cap on the second slide bar and the first slide bar to adjust the position of the sliding cap. Then, the second slide bar, the first slide bar and the sliding cap are locked and fixed by the fastening bolts to achieve two-way position adjustment of the sliding cap, enabling the sliding cap to be adjusted arbitrarily according to the compressor fixing structure. In combination with bolt fixing, the heat dissipation and noise reduction structure can be applicable to compressors of different specifications, expanding its applicable range.

At the middle position of the outer surface of one end of the inner casing 5, an intake pipe 12 is fixedly installed. At the outer surface of the other end of the inner casing 5, an exhaust pipe 13 is fixedly installed. Both the intake pipe 12 and the exhaust pipe 13 pass through both ends of the outer casing 3. The inner casing 5 is fixedly combined by a plurality of groups of splicing card boards 8. The inside of the splicing card board 8 is a hollow structure. A water collecting tray 7 is movably installed at the upper ends of the inner casing 5 and the outer casing 3. A fixed bottom plate 2 is arranged at the lower end of the inner casing 5. The inner casing 5 and the fixed bottom plate 2 are elastically connected by a spring 1. The lower end of the inner casing 5 and the outer casing 3 are butt-joint fixed by a fixing bracket 11. A fixed card cover 9 is provided at the front end of the outer casing 3.

[0036] A second fan 14 is fixedly installed on the outer surface of one end of the exhaust pipe 13, and a first fan 4 is fixedly installed on the outer surface of one end of the intake pipe 12. A wire pipe groove 10 for threading wires is provided in the middle of the front end of the inner sleeve box 5. The user places the refrigeration compressor inside the inner sleeve box 5. The outer sleeve box 3 and the inner sleeve box 5 are used to form a double sound insulation structure. At the same time, the inner sleeve box 5 and the outer sleeve box 3 are provided with sound insulation grooves in a zigzag structure to improve the sound insulation effect between the outer sleeve box 3 and the inner sleeve box 5. At the same time, the first fan 4 and the second fan 14 are respectively the intake and exhaust fans. When the first fan 4 and the second fan 14 operate, external air is introduced into the inner sleeve box 5 through the intake pipe 12 to cool the compressor inside the inner sleeve box 5. At the same time, the second fan 14 cooperates with the exhaust pipe 13 to extract the air, so that a high-speed cooling structure is formed inside the inner sleeve box 5 to avoid heat accumulation.

[0037] Two groups of fixing buckles 15 are fixedly installed on both sides of the fixed bottom plate 2. A lifting sleeve rod 16 used in cooperation with the spring 1 is movably installed on the upper end of the fixed bottom plate 2. With the setting of the spring 1 and the use of the lifting sleeve rod 16, an elastic buffer structure is formed between the outer sleeve box 3 and the fixed bottom plate 2, avoiding direct hard connection between the outer sleeve box 3 and the equipment. When the compressor inside the inner sleeve box 5 operates, the vibration between the compressor and the equipment can be effectively reduced, playing a role in shock absorption and noise reduction.

Secondly, the cross-shaped heat insulation structure formed by the wire pipe sleeve 30 and the fixed partition strip 17 can improve the structural strength of the splicing card board 8 while keeping the splicing card board 8 with good heat insulation effect.

[0039] The two ends of the splicing card board 8 are spliced and fixed through the docking plug 18, and slots for cooperating with the docking plug 18 are provided at both ends of the splicing card board 8.

A heat conducting pad 19 is fixedly installed on the outer surface of the lower end of the water collecting tray 7. The bottom of the heat conducting pad 19 is in an arc shape. The fixed sleeve rod 6 makes the water collecting tray 7 and the outer sleeve box 3 accurately docked. The function of the water collecting tray 7 is to collect the water discharged from the refrigerator, and heat conduction is carried out between the water collecting tray 7 and the compressor through the heat conducting pad 19, so that the water in the water collecting tray 7 can be used to cool the compressor.

[0041] On one side outer surface of the fixed card cover 9, a side cover 20 is fixedly installed. On the other side outer surface of the fixed card cover 9, a rectangular sleeve 23 is provided. When the refrigeration compressor is installed and used, the pipelines and wire bodies need to be docked.

By adding the fixed card cover 9, the installation operation of the wire pipes for the compressor in the inner sleeve box 5 can be carried out without reducing the sound insulation effect of the inner sleeve box 5 and the outer sleeve box 3.

[0042] On one end outer surface of the fixed card cover 9, an end cover 21 is fixedly installed. A card slot 22 is opened in the middle of the end cover 21. The wire pipe passes through one end of the fixed card cover 9. By covering the end cover 21, the wire pipe passes through the card slot 22 of the end cover 21. The use of the end cover 21 can improve the sealing effect of the fixed card cover 9.

[0043] On the inner side of the upper end of the fixing frame 11, a first sliding strip 25 and a second sliding strip 24 are movably installed. On the inner sides of the first sliding strip 25 and the second sliding strip 24, a sliding cap 26 for fixing the compressor is movably installed. By using the first sliding strip 25 and the second sliding strip 24 in cooperation with the sliding cap 26, it can be adjusted arbitrarily according to the fixed hole positions of the compressor. At the same time, the lower part of the fixing frame 11 is designed with a hollow structure to reduce the contact between the fixing frame 11 and the outer sleeve box 3.

At the same time, in cooperation with several groups of springs 1 on the fixed bottom plate 2, the noise generated during the operation of the compressor can be effectively reduced. During operation, the user places the refrigeration compressor inside the inner sleeve box 5, and the outer sleeve box 3 cooperates with the inner sleeve box 5 to form a double sound insulation structure. At the same time, the inner sleeve box 5 and the outer sleeve box 3 are provided with sound insulation grooves in a zigzag structure, which can effectively shield the noise generated during the operation of the compressor inside the inner sleeve box 5 and the outer sleeve box 3. Secondly, the inner sleeve box 5 is composed of multiple splicing card boards 8 spliced together.

By setting the wire pipe sleeve 30, the installation operation of the wire pipe for the compressor installed inside the inner sleeve box 5 can be carried out. Secondly, the cross-shaped heat insulation structure formed by the wire pipe sleeve 30 and the fixed partition strip 17 inside the splicing card board 8 can, while enhancing the structural strength of the splicing card board 8, keep the splicing card board 8 in good heat insulation effect. At the same time, in order to enable the compressor to be used normally inside the inner sleeve box 5 and the outer sleeve box 3, by installing a fixed card cover 9, the wire pipe installation operation of the compressor inside the inner sleeve box 5 and the outer sleeve box 3 can be satisfied. By installing the fixed card cover 9, the wire pipe can be bent at a right angle and extend from one end of the fixed card cover 9. By covering the end cover 21, the wire pipe passes through the card slot 22 of the end cover 21. By using the end cover 21, the sealing effect of the fixed card cover 9 can be improved, and the wire pipe installation operation of the compressor inside the inner sleeve box 5 can be carried out without reducing the sound insulation effect of the inner sleeve box 5 and the outer sleeve box 3.

During operation, since the first fan 4 and the second fan 14 are respectively an intake fan and an exhaust fan, when the first fan 4 and the second fan 14 operate, external air enters the inside of the inner casing 5 through the intake pipe 12 to cool the compressor inside the inner casing 5. At the same time, the second fan 14 is used in cooperation with the exhaust pipe 13 to extract the air, so that a high-speed air-cooling structure is formed inside the inner casing 5 to avoid heat accumulation. Thus, while not affecting the use of the inner casing 5 and the outer casing 3, the compressor can be kept in a stable state. Secondly, by setting the water collecting tray 7, when the compressor is installed in a refrigerator for use, the water collecting tray 7 can collect the water discharged during the daily use of the refrigerator.

The heat conduction operation is carried out between the water collecting tray 7 and the compressor through the heat conduction pad 19 to enhance the heat conduction effect between the water collecting tray 7 and the compressor. Thus, the water in the water collecting tray 7 can be used to cool the compressor. In cooperation with the use of the first fan 4 and the second fan 14, the refrigeration compressor has a dual cooling structure, enhancing the compressor cooling effect of the heat dissipation and noise reduction structure;
