[0002] The main function of an automotive air-conditioning radiator is to convert the high-temperature and high-pressure gaseous refrigerant sent by the compressor into a liquid refrigerant, and radiate the heat absorbed by the refrigerant in the vehicle into the atmosphere through the condenser.

[0003] In the prior art, in a Chinese patent document with the authorization announcement number CN219214656U, there is a record of an automotive air-conditioning radiator. This patent improves the stability of the frame lifted by the left support frame and the right support frame by setting a support and stabilization device, because the left support frame and the right support frame are both provided with lifting grooves, so as to avoid the radiator loosening and falling off due to long-term bumps and improve the service life.

[0004] It uses the provided support frame to lift the heat dissipation fins, and additional support frames need to be installed on the vehicle frame, which has great limitations in actual installation. Moreover, even if the support frames are installed, they are connected by bolts, and the bolts will loosen during long-term bumps, generating noise. Therefore, we propose an automotive air-conditioning radiator. Content of the Utility Model

[0024] This embodiment is a heat sink for an automotive air conditioner.

[0025] As Figures 1-4 shown, it includes heat dissipation fins 1 and a bracket 2. The heat dissipation fins 1 are fixed on the bracket 2. A pipe passing hole 3 is opened on one side of the heat dissipation fins 1. Ear plates 4 are fixedly installed at the rear ends of the outer surfaces of the upper and lower ends of the bracket 2. A connection and protection structure 5 is fixedly installed at the lower part of the front outer surface of the ear plate 4. The connection and protection structure 5 includes a fixing block 6, an extrusion rod 8, a sliding hole 9, an installation cavity 10, a first limiting plate 11, a compression spring 12, a second limiting plate 13, a screw rod 14, a threaded hole 15 and a knob 16. Through holes 7 are opened on the left and right sides of the lower part of the rear outer surface of the ear plate 4.

[0026] The fixed block 6 is fixedly installed at the lower part of the outer surface of the front end of the ear plate 4. The sliding holes 9 are opened on the left and right sides of the outer surface of the rear end of the fixed block 6, and the sliding holes 9 are located at one end of the through hole 7. The installation cavity 10 is opened inside the fixed block 6. The sliding holes 9 communicate with the installation cavity 10. The extrusion rod 8 passes through the through hole 7 and the sliding holes 9 and extends into the installation cavity 10. The number of extrusion rods 8 in a set of connection and protection structures 5 is two. The first limiting plate 11, the compression spring 12 and the second limiting plate 13 are all located in the installation cavity 10. The outer surfaces of one ends of the two extrusion rods 8 are fixedly connected to the left and right sides of the outer surface of one side of the first limiting plate 11. The compression spring 12 is fixedly installed between the outer surface of the other side of the first limiting plate 11 and the outer surface of one side of the second limiting plate 13. One end of the outer surface of the screw rod 14 is connected to the middle of the outer surface of the other side of the second limiting plate 13. The knob 16 is fixedly installed on the outer surface of the other end of the screw rod 14. The threaded hole 15 is opened in the middle of the outer surface of the front end of the fixed block 6. The screw rod 14 passes through the threaded hole 15, and the outer wall of the screw rod 14 is in threaded connection with the threaded hole 15. A sealing bearing is arranged between the screw rod 14 and the second limiting plate 13. The screw rod 14 is rotationally connected to the second limiting plate 13 through the sealing bearing. The outer surface of one side of the first limiting plate 11 is elastically connected to the outer surface of one side of the second limiting plate 13 through the compression spring 12. The outer walls of the first limiting plate 11 and the second limiting plate 13 are both in sliding connection with the installation cavity 10.

[0027] It should be noted that the present utility model is an automobile air-conditioning radiator fin. The connection, the bracket 2 and the pipe passing hole 3 described in the text all belong to the prior art and can be effectively known to those skilled in the art of the relevant technical field, so no further details will be given here. The provided connection and protection structure 5 is such that when the ear plate 4 is bolted to the vehicle frame, one end of the extrusion rod 8 is squeezed into the through hole 7. The extrusion rod 8 slides along the sliding hole 9. The extrusion rod 8 drives the first limiting plate 11 to squeeze the compression spring 12 in the installation cavity 10. After the compression spring 12 is compressed, the compression spring 12 has a restoring force, which can eliminate the looseness after bolt connection and improve the installation stability of the radiator fin. When the compression spring 12 is used for a period of time, its elastic force will weaken. By rotating the knob 16, the knob 16 drives the screw rod 14 to move along the threaded hole 15. The screw rod 14 drives the second limiting plate 13 to squeeze the compression spring 12 in the installation cavity 10, ensuring the elastic force of the compression spring 12 and improving the service life.
