[0030] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0031] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0032] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0033] like Figure 1-4 The image shows a refrigerator compressor cooling and noise reduction structure 10 provided in an embodiment of this application, including a noise reduction housing 1 and an air inlet device 2. The noise reduction housing 1 includes an air inlet 11, an air outlet 12, an air duct 14, and a receiving cavity 13 for accommodating the refrigerator compressor.

[0034] The air duct 14 is connected to the receiving cavity 13. One end of the air duct 14 is connected to the air inlet 11, and the other end of the air duct 14 is connected to the air outlet 12.

[0035] The air intake device 2 is connected to the noise reduction housing 1, and the air inlet of the air intake device 2 is connected to the air inlet hole 11.

[0036] The refrigerator compressor cooling and noise reduction structure 10 is applied to vehicle refrigerators, which can reduce the noise of the refrigerator compressor and ensure good heat dissipation.

[0037] The refrigerator compressor cooling and noise reduction structure 10 includes a noise reduction housing 1 and an air intake device 2. The noise reduction housing 1 has a receiving cavity 13 and an air duct 14. The refrigerator compressor is located inside the receiving cavity 13 and is enclosed by the noise reduction housing 1. The air duct 14 surrounds the outside of the receiving cavity 13 and is connected to the receiving cavity 13. When the refrigerator compressor generates sound, the noise reduction housing 1 absorbs part of the sound during sound propagation, thus obstructing sound propagation and reducing noise.

[0038] The noise-reducing housing 1 is provided with an air inlet 11 and an air outlet 12, which are respectively connected to the air duct 14. The air inlet device 2 has an air inlet that is connected to the air inlet 11. The air inlet device 2 generates airflow, which enters the noise-reducing housing 1 from the air inlet through the air inlet 11, then flows along the air duct 14 and exits from the air outlet 12. When the refrigerator compressor starts, it generates heat, which radiates into the air in the receiving cavity 13. As the airflow flows within the air duct 14, it drives the airflow in the receiving cavity 13, carrying away the heat. In this way, the heat emitted by the refrigerator compressor can be carried out of the noise-reducing housing 1 in a timely manner by the airflow, thereby dissipating heat in a timely manner and keeping the heat of the refrigerator compressor within the normal temperature range, ensuring the normal operation of the refrigerator compressor. Under the enclosure of the noise-reducing housing 1, the heat generated by the refrigerator compressor can accumulate to over 80°C, and after heat dissipation, the temperature can be reduced to below 60°C.

[0039] In one embodiment, such as Figure 1-2As shown, the noise reduction housing 1 is provided with multiple air outlets 12, which are spaced apart.

[0040] Specifically, the noise reduction housing 1 is provided with two air outlets 12. After the airflow generated by the air inlet device 2 enters the noise reduction housing 1, it can flow out from the two air outlets 12 respectively, thus increasing the rate at which the airflow exits the noise reduction housing 1 and improving the heat dissipation effect.

[0041] Optionally, multiple air outlets 12 can also be provided on the noise reduction housing 1.

[0042] In one embodiment, such as Figure 3-5 As shown, it also includes a mounting tray 3, a noise reduction housing 1 connected to the mounting tray 3, and an air inlet device 2 connected to the side of the mounting tray 3 away from the noise reduction housing 1.

[0043] Specifically, the refrigerator compressor cooling and noise reduction structure 10 also includes a mounting tray 3, which is located below the noise reduction housing 1, and the noise reduction housing 1 is mounted and fixed on the mounting tray 3. The bottom of the mounting tray 3 is connected to the air inlet device 2, which is opposite to the mounting tray 3. The mounting tray 3 provides a mounting position for the noise reduction housing 1 and the air inlet device 2, facilitating installation and assembly.

[0044] Optionally, the mounting tray 3 is provided with a mesh or through hole that communicates with the air inlet, and the air inlet of the air inlet device 2 communicates with the mesh and through hole on the mounting tray 3.

[0045] In one embodiment, such as Figure 3-5 As shown, the mounting tray 3 is provided with a mounting groove 31, the mounting groove 31 has a bottom wall 311, and the bottom wall 311 is provided with a connecting hole 312 that communicates with the air inlet 11. The air inlet device 2 includes a device frame 21 and an air inlet fan 22. The air inlet fan 22 is installed in the device frame 21, and the device frame 21 is installed in the mounting groove 31.

[0046] Specifically, a mounting groove 31 is formed by recessing the bottom of the mounting tray 3 towards the noise reduction housing 1. The mounting groove 31 has a bottom wall 311, which is a wall surface opposite to the mounting groove 31. A connecting hole 312 is provided on the bottom wall 311, which communicates with the air inlet 11.

[0047] The air intake device 2 includes a device frame 21 and an air intake fan 22. The air intake fan 22 is connected to the device frame 21 and generates airflow when it is activated. The device frame 21 is installed in the mounting slot 31, and the airflow generated by the air intake fan 22 enters the air intake hole 11 through the connecting hole 312. The mounting slot 31 defines the installation position of the air intake device 2 and restricts its movement after installation.

[0048] In one embodiment, such as Figure 3-5As shown, the bottom wall 311 of the groove includes a first end 3111 and a second end 3112. The distance between the first end 3111 and the opening of the mounting groove 31 is less than the distance between the second end 3112 and the opening of the mounting groove 31.

[0049] Specifically, the bottom wall 311 of the mounting groove is inclined, having a first end 3111 and a second end 3112. The distance from the first end 3111 to the groove opening is less than the distance from the second end 3112 to the groove opening. In other words, the depth of the mounting groove 31 at the first end 3111 is less than the depth of the mounting groove 31 at the second end 3112. This inclination of the bottom wall 311, along with the corresponding inclined connecting hole 312, allows the airflow generated by the fan 22 to enter the noise-reducing housing 1 in an inclined direction. This design increases the area of ​​the connecting hole 312, allowing more airflow to enter and improving heat dissipation efficiency.

[0050] In one embodiment, such as Figure 1 , Figure 3 and Figure 6 As shown, it also includes a connector 4, through which the noise-reducing housing 1 is detachably connected to the mounting tray 3. This arrangement facilitates the installation and removal of the noise-reducing housing 1. The noise-reducing housing 1 can be connected to and separated from the mounting tray 3, thus making installation and removal convenient.

[0051] In one embodiment, such as Figure 6 As shown, the connector 4 includes a pad 41, a connecting piece 42, and a connecting bolt 43. The pad 41 is placed on the mounting tray 3, the connecting piece 42 is connected to the noise reduction housing 1, and the connecting bolt 43 passes through the connecting piece 42 and the pad 41 and is connected to the mounting tray 3.

[0052] Specifically, the pad 41 has a certain degree of flexibility, which can play a cushioning role. The pad 41 is placed on the mounting tray 3, one side of the connecting piece 42 is connected to the noise reduction housing 1, and the other side is in contact with the pad 41. The connecting bolt 43 fixes the connecting piece 42 and the pad 41 to the mounting tray 3. This arrangement facilitates the installation and fixation of the noise reduction housing 1, and can buffer the external forces received by the noise reduction housing 1.

[0053] In one embodiment, such as Figure 6 As shown, the connector 4 also includes a clamping piece 44, which includes a main body piece 441 and two clamping legs 442. The two clamping legs 442 are spaced apart, and the connecting bolt 43 is clamped between the two clamping legs 442.

[0054] Specifically, the connector 4 also has a clamping piece 44, which consists of a main body piece 441 and two clamping legs 442. The two clamping legs 442 are connected to the main body piece 441 and are spaced apart, forming a clamping space between the two clamping legs 442. During installation, the two clamping legs 442 clamp the connecting bolt 43, restricting the rotation of the connecting bolt 43.

[0055] In one embodiment, such as Figure 6 As shown, the main body plate 441 is perpendicular to the clamping leg 442. The connection between the main body plate 441 and the clamping leg 442 is L-shaped, and the main body plate 441 provides a force-bearing position for easy operation.

[0056] In one embodiment, such as Figure 6-7 As shown, the connecting piece 42 includes a first piece 421 and a second piece 422 connected to the first piece 421. The first piece 421 is connected to the noise reduction housing 1, and the second piece 422 is connected to the connecting bolt 43. The first piece 421 and the second piece 422 are perpendicular to each other.

[0057] Specifically, the connecting piece 42 consists of a first piece 421 and a second piece 422. The first piece 421 is connected above the second piece 422, and the extending direction of the first piece 421 is perpendicular to the extending direction of the second piece 422. When the connecting piece 42 is connected, the first piece 421 is connected to the noise reduction housing 1, and the second piece 422 is connected to the connecting bolt 43. This structure of the connecting piece 42 is more reasonable, and the contact area between the first piece 421 and the second piece 422 and the corresponding connected object is larger, thus making the connection more secure.

[0058] Optionally, the first piece 421 is connected and fixed to the compressor inside the noise reduction housing 1, and extends outward through the noise reduction housing 1.

[0059] In one embodiment, such as Figure 3-4 As shown, the mounting tray 3 includes a tray body 32 and a support rod 33 for connection with an external frame. The support rod 33 is connected to the tray body 32 and extends outward. The noise reduction housing 1 is connected to the tray body 32.

[0060] Specifically, the mounting tray 3 has a tray body 32 and support rods 33. Two support rods 33 are spaced apart on the tray body 32, and the noise-reducing housing 1 is mounted on the tray body 32, located between the two support rods 33. One end of each support rod 33 is connected to the tray body 32, and the other end extends outwards. When the mounting tray 3 is installed, it cooperates with the external frame; the support rods 33 increase the connection area with the external frame, thus making the connection of the mounting tray 3 more secure.

[0061] Optionally, a material reduction hole 331 is provided on the support rod 33, thereby reducing the weight of the support rod 33.

[0062] In one embodiment, such as Figure 1-3 As shown, the noise reduction housing 1 is a rubber housing.

[0063] Specifically, the noise-reducing housing 1 is a rubber housing, meaning it is made of rubber material. Rubber material has good elasticity, making it less prone to damage and better protecting the refrigerator compressor. Furthermore, rubber can absorb noise more effectively, resulting in better noise reduction.

[0064] like Figure 1-9 The image shows a refrigerator compressor cooling assembly provided in an embodiment of this application, including the refrigerator compressor cooling and noise reduction structure 10 of any of the above claims.

[0065] The refrigerator compressor will be part of the vehicle frame as a component, and will include a cooling and noise reduction structure 10 for the refrigerator compressor. The specific structure and function of the cooling and noise reduction structure 10 are detailed above and will not be repeated here. The cooling and noise reduction structure 10 not only reduces noise but also provides excellent heat dissipation, ensuring the normal operation of the refrigerator compressor, thus improving the quality of the refrigerator compressor cooling component.

[0066] In one embodiment, such as Figure 1-9 As shown, the system also includes a cockpit frame 20, which comprises a first frame plate 201 and a second frame plate 202. A frame cavity 203 and an airflow channel 206 communicating with the frame cavity 203 are formed between the first frame plate 201 and the second frame plate 202. The refrigerator compressor cooling and noise reduction structure 10 is installed inside the frame cavity 203. A first grille 204 communicating with the interior of the cockpit is provided on the first frame plate 201, and a second grille 205 communicating with the interior of the cockpit is provided on the second frame plate 202. The first grille 204 and the second grille 205 are respectively connected to the airflow channel 206. A first fan (not shown) is provided on the inner side of the first frame plate 201, and the air inlet of the first fan is connected to the first grille 204. A second fan (not shown) is provided on the inner side of the second frame plate 202, and the air outlet of the second fan is connected to the second grille 205.

[0067] Specifically, the refrigerator compressor cooling assembly is installed inside the center armrest box of the cabin. The first frame plate 201 and the second frame plate 202 form the frame of the center armrest box. The area between the inner surfaces of the first frame plate 201 and the second frame plate 202 constitutes the frame cavity 203. A first grille 204 is provided on the first frame plate 201, and a first fan is connected to its inner surface. The first fan is an intake fan, and its air inlet communicates with the first grille 204. The airflow generated by the first fan enters the frame cavity 203 from the outside of the first frame plate 201 through the first grille 204. A second grille 205 is provided on the second frame plate 202, and a second fan is connected to its inner surface. The second fan is an exhaust fan, and its air outlet communicates with the second grille 205. The airflow generated by the second fan is exhausted into the cabin from the inside of the second frame plate 202 through the second grille 205. This creates an exchange and circulation of air between the cabin and the frame cavity 203, thereby expelling heat from the frame cavity 203 and keeping the temperature around the noise-reducing shell 1 stable.

[0068] The flow path of the entire airflow is as follows: the airflow enters the airflow channel 206 from the cabin through the first grille 204, then enters the frame cavity 203, then enters the noise reduction housing 1, then exits from the noise reduction housing 1 to the frame cavity 203, then returns to the airflow channel 206, and then exits from the second grille 205 back into the cabin.

[0069] One embodiment of this application provides a vehicle including a refrigerator compressor cooling assembly as described above. Vehicles equipped with this refrigerator compressor cooling assembly exhibit good noise reduction and the refrigerator compressor is less prone to damage.

[0070] In summary, this application provides a refrigerator compressor cooling and noise reduction structure 10, a refrigerator compressor cooling assembly, and a vehicle. The refrigerator compressor cooling and noise reduction structure 10 includes a noise reduction housing 1 and an air intake device 2. The noise reduction housing 1 includes an air inlet 11, an air outlet 12, an air duct 14, and a receiving cavity 13 for accommodating the refrigerator compressor. The air duct 14 communicates with the receiving cavity 13, with one end connected to the air inlet 11 and the other end connected to the air outlet 12. The air intake device 2 is connected to the noise reduction housing 1, and its air inlet communicates with the air inlet 11. The refrigerator compressor cooling assembly includes the refrigerator compressor cooling and noise reduction structure 10, and the vehicle includes the refrigerator compressor cooling assembly. The noise reduction housing 1 of the refrigerator compressor cooling and noise reduction structure 10 absorbs the noise generated by the refrigerator compressor, thereby reducing noise propagation. The air intake device 2 circulates air, quickly expelling the hot air inside the noise reduction housing 1 to the outside of the noise reduction housing 1, thereby reducing the heat of the refrigerator compressor. The refrigerator compressor cooling component and vehicle with the refrigerator compressor cooling and noise reduction structure 10 improve the passenger riding experience.

[0071] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0072] The above are merely the principles and preferred embodiments of this application.
