Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning scroll compressor technology, specifically to an automotive air conditioning scroll compressor with reinforced heat dissipation fins. Background Technology

[0002] In automotive air conditioning systems, the scroll compressor is a core component. Its operational stability and performance directly affect the cooling effect and lifespan of the entire system. During continuous operation, the compressor generates a significant amount of heat. If this heat cannot be dissipated effectively and promptly, the internal temperature of the compressor will rise sharply, leading to a series of serious problems. Currently, most common automotive air conditioning scroll compressors employ a single air-cooling structure, relying on heat sinks on the compressor casing and a cooling fan to accelerate airflow for heat dissipation. However, relying solely on air convection to remove heat is insufficient in high-temperature environments or when the compressor is under high load. The cooling effect is unsatisfactory and fails to meet the stringent cooling requirements of automotive air conditioning scroll compressors under various operating conditions. Utility Model Content

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1 to 4 As shown, this utility model provides an automotive air conditioning scroll compressor with reinforced heat dissipation fins, including a sleeve 1. The sleeve 1 is made of copper cylinder. A vent is opened at the tail of the sleeve 1. A first cooling fan 2 is fixedly installed at the vent by screws. The sleeve 1 is sleeved on the outside of the compressor body 11. Multiple first heat dissipation fins 3 are fixed between its inner sidewall and the outer shell of the compressor body 11 in a ring array. The first heat dissipation fins 3 are made of aluminum or copper fins. Their cross-section is wavy, which can increase the heat dissipation area of ​​the first heat dissipation fins 3. When the compressor body 11 is working, the heat generated can be transferred to the first heat dissipation fins 3. By starting the first cooling fan 2, an air duct can be formed in the sleeve 1, thereby removing the heat on the first heat dissipation fins 3 to achieve cooling of the compressor body 11.

[0027] A first heat exchange tube 4 is fixed on the first heat dissipation fin 3. The first heat exchange tube 4 is a spiral copper tube that is sleeved on the outside of the compressor body 11 and runs through all the first heat dissipation fins 3. The first heat exchange tube 4 and the first heat dissipation fin 3 are fixed by welding. During the operation of the compressor body 11, the heat on the first heat dissipation fin 3 can also be transferred to the first heat exchange tube 4.

[0028] A heat exchange plate 5 is bolted onto the sleeve 1. The heat exchange plate 5 is made of copper plate, on which a second heat exchange tube 6 is inlaid and welded. The second heat exchange tube 6 is a serpentine copper tube. One end of the second heat exchange tube 6 is connected to one end of the first heat exchange tube 4 through a circulation pump 7, and the other end of the second heat exchange tube 6 is directly connected to the other end of the first heat exchange tube 4. Cooling medium can flow inside the first heat exchange tube 4 and the second heat exchange tube 6. The circulation pump 7 allows the cooling medium to circulate within the first heat exchange tube 4 and the second heat exchange tube 6. When the cooling medium flows in the first heat exchange tube 4, the first heat exchange tube 4 can transfer the heat absorbed from the first heat dissipation fins 3 to the cooling medium, thereby further cooling the compressor body 11.

[0029] A semiconductor cooling chip 8 is also installed on the heat exchange plate 5. The cooling surface of the semiconductor cooling chip 8 is installed on the heat exchange plate 5, and a layer of thermally conductive silicone grease is applied between the two to enhance the heat conduction effect. When the semiconductor cooling chip 8 is working, it can cool the heat exchange plate 5, thereby cooling the cooling medium flowing in the second heat exchange tube 6. The serpentine design of the second heat exchange tube 6 can increase the residence time of the cooling medium in the second heat exchange tube 6, thereby effectively reducing the temperature of the cooling medium in the second heat exchange tube 6.

[0030] A second heat dissipation fin 9 is installed on the heating surface of the thermoelectric cooler 8. The second heat dissipation fin 9 is also made of aluminum or copper fins, and a layer of thermal grease is applied between them. A second cooling fan 10 is installed on the second heat dissipation fin 9 by screws. Through the cooperation of the second heat dissipation fin 9 and the second cooling fan 10, the heating surface of the thermoelectric cooler 8 can be cooled, thereby ensuring that the thermoelectric cooler 8 can effectively cool.

[0031] Working principle and usage process of this utility model:

[0032] When using this automotive air conditioning scroll compressor with reinforced heat dissipation fins, the car's air conditioning system is first started, and the compressor body 11 begins to work. During the compression of the refrigerant, a large amount of heat is generated, which is transferred to the first heat dissipation fins 3 in contact with the compressor body 11's outer casing. Because the first heat dissipation fins 3 have a wavy cross-section, they effectively increase the heat dissipation area and accelerate heat dissipation. The first cooling fan 2 at the rear vent of the sleeve 1 is turned on to ventilate and dissipate heat inside the sleeve 1, accelerating the airflow around the first heat dissipation fins 3 and helping them dissipate heat. Simultaneously, the circulation pump 7 starts, and the cooling medium in the first heat exchange tube 4 begins to flow, fully absorbing the heat from the first heat dissipation fins 3. The heat absorbed by the cooling medium in the first heat exchange tube 4 is pumped to the second heat exchange tube 6 by the circulation pump 7. At the same time, the semiconductor refrigeration chip 8 works, and its cooling surface quickly conducts away the heat from the heat exchange plate 5 and the second heat exchange tube 6, thereby reducing the temperature of the cooling medium. As the cooling medium continuously circulates in the first heat exchange tube 4 and the second heat exchange tube 6, it can continuously carry away and dissipate the heat generated by the compressor body 11, thereby achieving enhanced heat dissipation and ensuring the normal operation of the automotive air conditioning scroll compressor. The heat generated by the heating surface of the semiconductor refrigeration chip 8 is transferred to the second heat dissipation fin 9, and the second cooling fan 10 is turned on to blow air onto the second heat dissipation fin 9 to dissipate the heat.

[0033] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
