Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a heat dissipation structure for a refrigeration machine with noise reduction function. Background Technology

[0002] A refrigeration machine is a device that achieves refrigeration through energy conversion. It is mainly used to transfer the heat of a low-temperature object to the surrounding medium, thereby obtaining cooling.

[0003] During the operation of a refrigeration unit, heat dissipation is a crucial factor in ensuring its stable operation. However, traditional refrigeration unit heat dissipation structures often use rigid connections to install cooling fans and heat dissipation channels. The vibrations generated during operation cannot be effectively buffered, resulting in significant noise. At the same time, the turbulent airflow within the heat dissipation channels not only reduces heat dissipation efficiency but also generates additional noise due to airflow friction. These noise problems not only affect the comfort of the working environment but may also adversely affect the service life of the equipment. Therefore, it is necessary to design a refrigeration unit heat dissipation structure with noise reduction function to address the above issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling system with noise reduction capabilities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A refrigeration unit heat dissipation structure with noise reduction function includes a refrigeration unit body. A connecting frame is fixedly installed on the outer wall of the refrigeration unit body. Two sliders are slidably installed inside the connecting frame via a rhomboid rod. The outer walls of the two sliders are connected to the inner wall of the connecting frame via an elastic mechanism. A first connecting frame is fixedly installed on the upper surface of each of the two sliders. A second connecting frame is rotatably connected to each of the two first connecting frames via a connecting plate. A mounting plate is fixedly connected to the outer walls of the two second connecting frames. Two damping telescopic rods are fixedly installed on the outer wall of the refrigeration unit body via a support mechanism. The telescopic ends of the two damping telescopic rods are fixedly connected to the upper surface of the mounting plate. An air intake channel that mates with the air intake port of the refrigeration unit body is fixedly installed on the outer wall of the air intake channel through an installation opening. A vibration damping pad that mates with the outer wall of the refrigeration unit body is fixedly installed at one end of the air intake channel. A cooling fan is fixedly installed inside the air intake channel. A protective filter is fixedly installed at the other end of the air intake channel.

[0006] Preferably, the elastic mechanism includes a buffer spring installed on the outer wall of the prism rod, and the two ends of the buffer spring are elastically connected to the inner wall of the connecting frame and the outer wall of the slider, respectively.

[0007] Preferably, the support mechanism includes a support plate fixedly installed on the outer wall of the refrigerator body, and both damping telescopic rods are fixedly installed on the bottom wall of the support plate.

[0008] Preferably, an exhaust channel that matches the heat dissipation outlet is fixedly installed on the outer wall of the refrigerator body, and a sound-absorbing cotton sleeve is fixedly installed inside the exhaust channel.

[0009] Preferably, multiple turbulence plates are fixedly installed inside the exhaust channel, and the multiple turbulence plates are distributed in a labyrinthine manner.

[0010] The beneficial effects of this utility model are: 1. By setting up components such as prismatic rods, sliders, buffer springs, and damping telescopic rods, the prismatic rods, together with the sliders and buffer springs, form an elastic connection structure. When the refrigerator vibrates during operation, the sliders can slide along the prismatic rods, and the buffer springs absorb vibration energy through their own deformation, effectively slowing down the transmission of vibration. At the same time, the damping telescopic rods utilize their unique damping characteristics to further suppress the amplification and propagation of vibration, significantly reducing the noise generated by structural vibration.

[0011] 2. By setting up components such as exhaust channels, sound-absorbing cotton sleeves and turbulence plates, the sound-absorbing cotton sleeves can efficiently absorb the noise generated when hot air is discharged, converting noise energy into heat energy and dissipating it, thereby reducing noise intensity at the source. The labyrinthine distribution of turbulence plates can effectively sort out turbulent airflow, making the airflow more regular and orderly, and reducing additional noise caused by airflow collision and friction.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5 The cooling structure of the refrigerator with noise reduction function includes a refrigerator body 1. A connecting frame 2 is fixedly installed on the outer wall of the refrigerator body 1. Two sliders 4 are slidably installed inside the connecting frame 2 through a rhomboid rod 3. The outer walls of the two sliders 4 are connected to the inner wall of the connecting frame 2 through an elastic mechanism. A first connecting frame 6 is fixedly installed on the upper surface of the two sliders 4. A second connecting frame 8 is rotatably connected inside the two first connecting frames 6 through a connecting plate 7. An mounting plate 9 is fixedly connected to the outer wall of the two second connecting frames 8. Two damping telescopic rods 11 are fixedly installed on the outer wall of the refrigerator body 1 through a support mechanism. The telescopic ends of the two damping telescopic rods 11 are fixedly connected to the upper surface of the mounting plate 9. An air intake channel 12 that cooperates with the air intake port of the refrigerator body 1 is fixedly installed on the outer wall of the mounting plate 9 through an installation opening. A vibration damping pad 13 that cooperates with the outer wall of the refrigerator body 1 is fixedly installed at one end of the air intake channel 12. A cooling fan 14 is fixedly installed inside the air intake channel 12. A protective filter 15 is fixedly installed at the other end of the air intake channel 12.

[0016] The elastic mechanism includes a buffer spring 5 installed on the outer wall of the prism rod 3. The two ends of the buffer spring 5 are elastically connected to the inner wall of the connecting frame 2 and the outer wall of the slider 4, respectively.

[0017] Furthermore, the buffer spring 5 continuously applies an elastic restoring force to the slider 4, causing the slider 4 to quickly return to its original position after vibration, maintaining the stability of the vibration reduction structure, and absorbing vibrations of different frequencies to reduce the risk of resonance.

[0018] The support mechanism includes a support plate 10 fixedly installed on the outer wall of the refrigeration unit body 1, and two damping telescopic rods 11 fixedly installed on the bottom wall of the support plate 10.

[0019] Furthermore, the support plate 10 provides stable support for the damping telescopic rod 11, optimizes the force transmission path, ensures that the damping telescopic rod 11 effectively plays its vibration reduction role, and enhances the stability of the entire heat dissipation structure.

[0020] An exhaust channel 16 that matches the heat dissipation outlet is fixedly installed on the outer wall of the refrigeration unit body 1, and a sound-absorbing cotton sleeve 17 is fixedly installed inside the exhaust channel 16.

[0021] Furthermore, the sound-absorbing cotton sleeve 17 absorbs exhaust noise through its porous structure, converting sound energy into heat energy, effectively reducing the aerodynamic noise generated by the exhaust.

[0022] Multiple turbulence plates 18 are fixedly installed inside the exhaust channel 16, and the multiple turbulence plates 18 are distributed in a labyrinth.

[0023] Furthermore, the labyrinthine turbulence plate 18 extends the airflow path, guides turbulent airflow, and allows it to be discharged smoothly, reducing noise generated by airflow collisions, while increasing the contact time between hot air and the outside environment, thus improving heat dissipation efficiency.

[0024] When this utility model is in use, during the operation of the refrigeration unit, the cooling fan 14 starts, and the air enters the air intake channel 12 after being filtered by the protective filter 15. Since the vibration damping pad 13 installed at one end of the air intake channel 12 is in close contact with the outer wall of the refrigeration unit body 1, it effectively blocks the vibration generated by the operation of the cooling fan 14 from being transmitted to the refrigeration unit body 1, reducing vibration noise. The air entering the air intake channel 12 is driven by the cooling fan 14 and flows quickly to the heat dissipation air intake of the refrigeration unit body 1 to dissipate heat for the heat source components inside the refrigeration unit. After being cooled, the hot air is discharged from the heat dissipation outlet of the refrigerator body 1 and then enters the exhaust channel 16. The sound-absorbing cotton sleeve 17 inside the exhaust channel 16 first absorbs the noise carried by the discharged hot air, reducing the noise intensity. Then, the hot air flows meandering between the labyrinthine turbulence plates 18, and the turbulent airflow is guided, making the airflow more stable. This not only reduces the noise caused by airflow turbulence but also prolongs the residence time of the hot air in the exhaust channel 16, allowing the sound-absorbing cotton sleeve 17 to absorb noise more fully. At the same time, the noise generated during the operation of the refrigerator is reduced. The vibration generated is partly transmitted to the connecting frame 2 through the refrigerator body 1. Due to the rotational connection between the first connecting frame 6 and the second connecting frame 8, the mounting plate 9 can move up and down to a certain extent. The buffer spring 5 on the prismatic rod 3 inside the connecting frame 2 plays an elastic buffering role, reducing the displacement of the slider 4 caused by vibration and reducing vibration transmission. The other part of the vibration is absorbed by the damping telescopic rod 11. Its damping characteristics during the extension and contraction process effectively suppress the transmission and amplification of vibration. Multiple vibration reduction and noise reduction measures work together to ultimately achieve low noise and efficient heat dissipation of the refrigerator during operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
