Description

Technical Field

[0001] This utility model relates to the field of noise reduction and heat dissipation technology for refrigeration equipment, and particularly to a compressor compartment heat dissipation and noise reduction device and a refrigeration equipment including the device. Background Technology

[0002] As people's living standards continue to improve, refrigerators have gradually become one of the essential home appliances. Furthermore, as people increasingly value a comfortable and pleasant user environment, noise levels have become a more important performance indicator. For refrigerators, the compressor compartment is one of the main sources of noise. On the one hand, the compressor generates radiated noise during operation; on the other hand, the cooling airflow entering the compartment creates eddies due to bends and turns, resulting in noise.

[0003] Currently, a sound-absorbing structure, such as a sound-absorbing cavity or sound-absorbing hole, is used on the cooling fan to absorb the noise generated by the fan or airflow. However, this method results in a larger fan structure, which in turn requires the compressor compartment to occupy more space inside the refrigerator, affecting the usable space of the refrigerator. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defect that the refrigerator compressor compartment will occupy more internal space when using a fan with sound absorption effect. The present invention provides a compressor compartment heat dissipation and noise reduction device and a refrigeration device including the present invention.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] In a first aspect, this utility model provides a compressor compartment heat dissipation and noise reduction device, comprising: a compressor compartment, wherein two ventilation openings are provided on the side wall of the compressor compartment, the two ventilation openings are connected within the compressor compartment to form a heat dissipation channel, and along the extension direction of the heat dissipation channel, the heat dissipation channel includes a first channel sidewall and a second channel sidewall connected to each other, the extension direction of the first channel sidewall intersecting the extension direction of the second channel sidewall; a flow guide is disposed at the connection position of the first channel sidewall and the second channel sidewall, the flow guide has an arc-shaped flow guide surface formed on the flow guide, the arc-shaped flow guide surface has a first side and a second side opposite to each other, the first side is smoothly connected to the first channel sidewall, and the second side is smoothly connected to the second channel sidewall; the flow guide is formed of a porous sound-absorbing material.

[0007] The compressor compartment heat dissipation and noise reduction device provided in this embodiment includes a compressor compartment. Two ventilation openings are formed on the side wall of the compressor compartment, creating a heat dissipation channel. The heat dissipation channel includes a first channel sidewall and a second channel sidewall connected along its extension direction. The extension directions of the first channel sidewall and the second channel sidewall intersect. Furthermore, the compressor compartment heat dissipation and noise reduction device also includes a flow guide. The flow guide is located at the connection point of the first and second channel sidewalls. The flow guide has an arc-shaped flow guide surface. The first side of the arc-shaped flow guide surface can smoothly connect with the first channel sidewall, and the second side can smoothly connect with the second channel sidewall. Thus, the airflow passing through the first channel sidewall can be smoothly guided by the arc-shaped flow guide surface to flow to the second channel sidewall. The second channel sidewall avoids changes in airflow velocity or turbulence caused by sudden changes in airflow direction, ensuring smooth and stable airflow and reducing airflow noise to a certain extent. Furthermore, at least part of the guide element is made of porous sound-absorbing material. When airflow passes through the guide element, the porous sound-absorbing material can eliminate noise to a certain extent, thereby further reducing noise. Compared with the existing technology of setting a sound-absorbing structure on the fan, the compressor compartment heat dissipation and sound-absorbing device provided in this embodiment does not require modification of the fan structure. It only requires smooth connection between the first channel wall and the de-channel wall through the guide element. At the same time, the use of sound-absorbing material does not require more space and has a better noise reduction effect.

[0008] Preferably, one end of the first channel sidewall is connected to the second channel sidewall, and the other end of the first channel sidewall extends to a vent to form the opening edge of the vent; the first sidewall is connected to the opening edge of the vent.

[0009] This design allows the airflow guide to begin its function from the vent, resulting in a smoother flow of air. Furthermore, the extension length of the airflow guide can be longer, thus improving noise reduction and sound attenuation.

[0010] Preferably, the guide member has a first mounting surface, a second mounting surface, and an arc-shaped guide surface that are connected end to end in sequence, and a bending angle is formed at the connection between the first mounting surface and the second mounting surface; the bending angle is located in the bending area formed between the first channel sidewall and the second channel sidewall, and the first mounting surface is in contact with the first channel sidewall, and the second mounting surface is in contact with the second channel sidewall.

[0011] This design allows the guide component to fit completely against the sidewalls of the first and second channels. This not only prevents gaps between the guide component and the sidewalls of the first and second channels from affecting the stable flow of air, but also ensures that when the airflow passes through the arc-shaped guide surface of the guide component, the air pressure force exerted by the airflow on the arc-shaped guide surface allows the guide component to stably abut against the bending area, thus guaranteeing the structural stability of the guide component during use.

[0012] Preferably, the compressor compartment heat dissipation and noise reduction device further includes an air guide box, which has an air guide inlet and an air guide outlet. The plane where the air guide inlet is located intersects with the plane where the vent is located, and the air guide outlet is oriented towards the vent. An air guide channel extends between the air guide inlet and the air guide outlet, forming a third channel wall. The third channel wall has a smooth transition from the air guide inlet to the air guide outlet.

[0013] This configuration allows the airflow direction to be changed through the air guide box, thus adapting to various different airflow directions. While ensuring stable airflow, it also improves the flexibility of the aforementioned compressor compartment heat dissipation and noise reduction device.

[0014] Preferably, a diverter plate is provided inside the air guide box, and the two sides of the diverter plate are connected to the inner wall of the air guide box to divide the air guide channel into multiple diverter channels; the two ends of the diverter plate extend to the air guide inlet and the air guide outlet.

[0015] This design allows the airflow to be guided through multiple layers after it flows into the air guide channel. This allows the airflow to be sorted through multiple flow channels, thus forming a more stable flow state within the air guide channel and further reducing aerodynamic noise.

[0016] Preferably, a guide plate is provided inside the air guide box. The guide plate has a first side and a second side opposite to each other. The first side is located near the air guide inlet, and the second side is located near the air guide outlet. A connecting shaft is provided through the first side, and the guide plate is rotatably connected to the box wall of the air guide box through the connecting shaft.

[0017] By setting up a deflector, the airflow can be stabilized to a certain extent. Furthermore, since the deflector is rotatably connected to the wall of the air guide box, it can always maintain the same orientation as the airflow under the action of the airflow, thus guiding the airflow under any size and further improving the stabilization effect.

[0018] Preferably, the surface of the guide plate is convex in an arc shape along the direction from the first side to the second side. This design helps to reduce aerodynamic resistance within the airflow channel, improves flow stabilization, and thus reduces aerodynamic noise.

[0019] Preferably, at least a portion of the deflector is made of porous sound-absorbing material. This arrangement allows the airflow to achieve a certain degree of noise reduction as it passes through the deflector.

[0020] Preferably, there are multiple guide vanes, which are arranged at intervals along the direction from the air inlet to the air outlet, so that the airflow is stabilized multiple times through multiple guide vanes to further improve the flow stabilization effect.

[0021] Secondly, this utility model also provides a refrigeration device, which includes the compressor compartment heat dissipation and noise reduction device as described above.

[0022] Preferably, the refrigeration equipment includes a housing, and the compressor compartment heat dissipation and noise reduction device is disposed inside the housing; the housing is provided with a heat dissipation grille, the heat dissipation grille is located at a position corresponding to the compressor compartment heat dissipation and noise reduction device, the heat dissipation grille is formed with a plurality of heat dissipation vents connecting the interior of the housing to the outside, and the heat dissipation vents extend downward at an angle from the inside to the outside of the housing.

[0023] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model. Attached Figure Description

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0037] like Figures 2-6 As shown in the figure, this utility model embodiment provides a compressor compartment heat dissipation and noise reduction device, which includes a compressor compartment 1. The compressor compartment 1 has two ventilation openings 1a on its side wall, and the two ventilation openings 1a are connected within the compressor compartment 1 to form a heat dissipation channel 1b.

[0038] Specifically, a condenser fan 2 and a compressor (not shown in the figure) are installed in the heat dissipation channel 1b. One vent 1a forms an airflow inlet, and the other vent 1a forms an airflow outlet. Through the operation of the condenser fan 2, external air can be driven to flow into the heat dissipation channel 1b from one vent 1a, and after air cooling the compressor in the heat dissipation channel 1b, it flows out through the other vent 1a.

[0039] For example, the condenser fan 2 is an axial flow fan, with its outer side connected to the channel wall of the heat dissipation channel 1b for fixation. The compressor is located downstream of the condenser fan 2. In other embodiments, the compressor may be located upstream of the condenser fan 2.

[0040] Furthermore, along the extension direction of the heat dissipation channel 1b, the heat dissipation channel 1b includes a first channel sidewall 11 and a second channel sidewall 12 connected to each other, and the extension direction of the first channel sidewall 11 intersects the extension direction of the second channel sidewall 12.

[0041] In other words, along the extension direction of the heat dissipation channel 1b, a bend will be formed at the internal position of the heat dissipation channel 1b. This is due to the setting position of the vent 1a or the extension shape of the channel. For example, when the heat dissipation channel 1b includes at least two channel segments, the channel walls of the two channel segments correspond to the first channel sidewall 11 and the second channel sidewall 12, respectively.

[0042] If the two channel segments extend in different directions, the extension directions of the first channel sidewall 11 and the second channel sidewall 12 will intersect, and a bend will be formed at the junction of the first channel sidewall 11 and the second channel sidewall 12. The formation of the bend will cause the airflow velocity to change when passing through the bend, and may even induce turbulence, leading to an increase in airflow noise.

[0043] Furthermore, the compressor compartment heat dissipation and noise reduction device provided in this embodiment of the present invention also includes a flow guide 3, which is disposed at the connection position of the first channel sidewall 11 and the second channel sidewall 12. The flow guide 3 has an arc-shaped flow guide surface 31, which has opposing first and second sides. The first side is smoothly connected to the first channel sidewall 11, and the second side is smoothly connected to the second channel sidewall 12.

[0044] Specifically, the arc-shaped guide surface 31 of the guide member 3 can block the bending angle formed at the junction of the first channel sidewall 11 and the second channel sidewall 12. At the same time, the arc-shaped guide surface 31 smoothly connects with the first channel sidewall 11 and the second channel sidewall 12 respectively, so that the airflow can be guided by the arc-shaped guide surface when it flows through the first channel sidewall 11 and the second channel sidewall 12, so as to achieve smooth airflow and avoid large changes in flow velocity and turbulence, thereby avoiding the generation of large airflow noise.

[0045] Based on the above, at least a portion of the flow guide 3 is made of porous sound-absorbing material. This arrangement allows the porous sound-absorbing material to partially eliminate noise generated by the airflow as it passes through the flow guide 3, thereby further reducing noise while ensuring smooth airflow.

[0046] In a specific implementation, in this embodiment of the utility model, the flow guide 3 can be an integral structure, and its entirety is made of porous sound-absorbing material.

[0047] In summary, the compressor compartment heat dissipation and noise reduction device provided in this embodiment includes a compressor compartment 1. Two ventilation openings 1a are formed on the side wall of the compressor compartment 1, creating a heat dissipation channel 1b. The heat dissipation channel 1b includes a first channel sidewall 11 and a second channel sidewall 12 connected along its extension direction. The extension directions of the first channel sidewall 11 and the second channel sidewall 12 intersect. Furthermore, the compressor compartment heat dissipation and noise reduction device also includes a flow guide 3, which is located at the connection point of the first channel sidewall 11 and the second channel sidewall 12. The flow guide 3 has an arc-shaped flow guide surface 31. The first side of the arc-shaped flow guide surface 31 can smoothly connect with the first channel sidewall 11, and the second side can smoothly connect with the second channel sidewall 12. Thus, the flow guide 3 blocks the bending angle formed by the intersection of the first channel sidewall 11 and the second channel sidewall 12. This design allows the airflow passing through the side wall 11 of the first channel to be smoothly guided to the side wall 12 of the second channel by the arc-shaped guide surface 31. This avoids changes in flow velocity or turbulence caused by sudden changes in flow direction, ensuring the smoothness and stability of airflow. This reduces airflow noise to a certain extent. Furthermore, at least part of the guide component 3 is made of porous sound-absorbing material. Thus, when the airflow passes through the guide component 3, the noise can be eliminated to a certain extent by the porous sound-absorbing material, further reducing noise. Compared with the existing method of setting a sound-absorbing structure on the fan, the compressor compartment heat dissipation and sound-absorbing device provided in this embodiment does not require modification of the fan structure. It only requires the guide component 3 to smoothly connect the first channel wall and the second channel wall. At the same time, the use of sound-absorbing material does not require more space and has a better noise reduction effect.

[0048] For example, the porous sound-absorbing material used in the flow guide 3 can be sound-absorbing cotton or polyurethane foam.

[0049] like Figure 3 and Figure 4 As shown, the compressor compartment 1 structure further includes a compartment bottom plate 13, a front panel 14 and a rear cover plate 15. The compartment bottom plate 13, the front panel 14 and the rear cover plate 15 together form a cylindrical structure so that the cylindrical structure forms a heat dissipation channel 1b. The condenser fan 2 and the compressor are installed inside the cylindrical structure.

[0050] For example, the rear cover plate 15 extends vertically and connects to the rear side of the bottom plate 13, which in turn extends horizontally. Corresponding to the bottom plate 13 and the rear cover plate 15, the front panel 14 can be formed into two segments corresponding to the bottom plate 13 and the rear cover plate 15, respectively, and connected to the front side of the bottom plate 13 and the top of the rear cover plate 15, thus forming a cubic cylindrical structure. Furthermore, a left and right side plate 16 is respectively installed at both ends of this cylindrical structure to close both ends.

[0051] Furthermore, the two vents 1a can be correspondingly opened on the side plate 16 of the front bulkhead 14 and located at both ends of the cylindrical structure. This allows the heat dissipation channel 1b to be as long as possible, thereby allowing more air to flow into the heat dissipation channel 1b, which is more conducive to the heat dissipation of the compressor.

[0052] Based on the above structural design, the formation of the heat dissipation channel 1b and the air guiding method of the air guiding component 3 in this embodiment will be specifically explained:

[0053] like Figure 1 and Figure 4 As shown, since the two side plates 16 seal both ends of the cylindrical structure surrounded by the bottom plate 13, the front bulkhead 14 and the rear cover plate 15, and the ventilation opening 1a is opened on the front side plate 16 section of the front bulkhead 14, the side plates 16 form the first channel side wall 11, and the rear cover plate 15 forms the second channel side wall 12.

[0054] Thus, the area opposite the vent 1a is the bend formed by the first channel sidewall 11 and the second channel sidewall 12, and the guide element 3 is correspondingly positioned at this location. Therefore, when the airflow enters the heat dissipation channel 1b through the vent 1a, it is guided by the arc-shaped guide surface 31 on the guide element 3, smoothly transitioning to the same flow direction as the extending direction of the second channel sidewall 12.

[0055] Furthermore, since each end of the cylindrical structure has a side plate 16 structure, that is, each of the two side plates 16 forms a first channel side wall 11, a guide member 3 structure as described above can be provided at the connection between the two first channel side walls 11 and the second channel side wall 12.

[0056] In other embodiments, if one end of the cylindrical structure directly discharges air, then it is not necessary to install a guide element 3 at the air outlet. In general, when using the guide element 3, the placement and number of the guide element 3 can be adaptively adjusted according to the extension shape of the heat dissipation channel 1b. For example, when the heat dissipation channel 1b has multiple bends, a guide element 3 structure can be installed at each bend.

[0057] Of course, in other embodiments, the compressor compartment 1 may also be formed as a cylindrical structure of other shapes, or may be formed by enclosing it with other types of plate segments. Furthermore, in other embodiments, the two vents 1a may also be located at other positions within the compressor compartment 1.

[0058] Furthermore, in some embodiments, when one end of the first channel sidewall 11 is connected to the second channel sidewall 12, and the other end of the first channel sidewall 11 extends to a vent 1a, the other end of the first channel sidewall 11 forms the opening edge of the vent 1a. Based on this, the first side of the guide member 3 can extend to connect with the opening edge of the vent 1a. That is, the guide member 3 begins to guide airflow from the location of the vent 1a, allowing the incoming airflow to flow more smoothly. Furthermore, the extension length of the guide member 3 can be longer, thereby improving noise reduction and sound attenuation effects.

[0059] In a specific implementation, for example, when the first channel sidewall 11 is formed by the side plate 16, the first side of the guide member 3 extends to the edge of the side plate 16, so that the guide member 3 covers the entire side plate 16.

[0060] In addition, in one specific implementation, the top and bottom of the flow guide 3 are extended to connect with the bottom plate 13 of the compressor compartment 1 and the top plate segment of the front panel 14 to achieve flow guidance at any position along the height direction of the heat dissipation channel 1b.

[0061] Specifically, in setting and installing the flow guide 3 structure, in some embodiments, the flow guide 3 can form a first mounting surface 32, a second mounting surface 33, and an arc-shaped flow guide surface 31. A bending angle is formed at the connection between the first mounting surface 32 and the second mounting surface 33, and the bending angle is located within the bending area formed between the first channel sidewall 11 and the second channel sidewall 12. Furthermore, the first mounting surface 32 is in contact with the first channel sidewall 11, and the second mounting surface 33 is in contact with the second channel sidewall 12. See [link to relevant documentation] for details. Figure 2 and Figure 5 As shown.

[0062] Thus, the bend in the flow guide 3 at the junction of the first mounting surface 32 and the second mounting surface 33 matches the bend area enclosed by the first channel sidewall 11 and the second channel sidewall 12. The flow guide 3 can fit completely against the first channel sidewall 11 and the second channel sidewall 12. This not only ensures that there are no gaps between the flow guide 3 and the first channel sidewall 11 and the second channel sidewall 12 that would affect the stable flow of air, but also ensures that when the airflow passes through the arc-shaped flow guide surface 31 of the flow guide 3, the air pressure force of the airflow on the arc-shaped flow guide surface 31 makes the flow guide 3 stably abut against the bend area, thus ensuring the structural stability of the flow guide 3 during use.

[0063] The above configuration enables stable and smooth airflow through the guide 3 when the vent 1a is directly connected to the outside. If the airflow cannot flow in along the direction perpendicular to the plane where the vent 1a is located, other structures can be set to introduce the airflow.

[0064] like Figure 7-9 As shown, in some embodiments, the compressor compartment heat dissipation and noise reduction device further includes an air guide box 4, which has an air guide inlet 41 and an air guide outlet 42. The plane where the air guide inlet 41 is located intersects with the plane where the ventilation opening 1a is located. Further, an air guide channel 4a extends between the air guide inlet 41 and the air guide outlet 42, with the air guide outlet 42 facing the ventilation opening 1a. The air guide channel 4a has a third channel wall 43, which smoothly transitions from the air guide inlet 41 to the air guide outlet 42.

[0065] In this way, the airflow direction can be changed by the air guide box 4, thereby adapting to various different airflow in and out directions. While ensuring airflow stability, the flexibility of the above-mentioned compressor compartment heat dissipation and noise reduction device is improved.

[0066] like Figure 7-8 As shown, in a specific implementation, an air guide box 4 can be provided at each vent 1a. Of course, in other embodiments, the number of air guide boxes 4 can also be set to flexibly adapt to the airflow direction of the incoming and outgoing air.

[0067] like Figure 7 As shown, in one implementation, the air guide box 4 can adopt a hollow box-type structure, with the air guide inlet 41 and air guide outlet 42 respectively located at positions corresponding to the airflow direction and the ventilation opening 1a. For example Figure 2 and Figure 7 , Figure 8 As shown, when air is introduced from both sides, the air inlet 41 and the air outlet 42 can be respectively opened on two side walls that are perpendicular to each other.

[0068] Furthermore, for the two ventilation openings 1a that respectively provide air intake and exhaust, the positions of the air inlet 41 and air outlet 42 on the air guide box 4 can be adjusted accordingly to adapt to the required airflow direction. Alternatively, the air guide box 4 can be swapped and installed.

[0069] like Figure 8 As shown, in some embodiments, a diversion plate 44 is provided inside the air guide box 4. The two sides of the diversion plate 44 are connected to the inner wall of the air guide box 4 to divide the air guide channel 4a into multiple diversion channels. Furthermore, the two ends of the diversion plate 44 extend to the air guide inlet 41 and the air guide outlet 42.

[0070] This configuration allows the airflow to be guided through multiple layers after it flows into the air guide channel 4a. This allows the airflow to be sorted through multiple flow channels, thus forming a relatively stable flow state within the air guide channel 4a, thereby further reducing aerodynamic noise.

[0071] In a specific implementation, the diverter plate 44 can divide the air guide channel 4a into multiple diverter channels with the same cross-sectional size, so that the airflow velocity and flow rate in each diverter channel are basically the same. Furthermore, in this embodiment, one diverter plate 44 is set inside the air guide channel 4a; of course, in other embodiments, the number of diverter plates 44 can also be set to other quantities.

[0072] To further reduce noise, in some embodiments, a guide plate 5 is also provided inside the air guide channel 4a. The guide plate 5 has a first side 51 and a second side 52 facing each other. The first side 51 is located near the air guide inlet 41, and the second side 52 is located near the air guide outlet 42. Furthermore, a connecting shaft 53 is provided through the first side 51, and the guide plate 5 is rotatably connected to the wall of the air guide box 4 through the connecting shaft 53.

[0073] By setting the deflector 5, a certain degree of airflow stabilization effect can be achieved. Furthermore, since the deflector 5 is rotatably connected to the wall of the air guide box 4, the deflector 5 can always maintain the same orientation as the airflow under the action of the airflow, thereby guiding the airflow under any size and further improving the airflow stabilization effect.

[0074] For example, in some embodiments, the surface of the guide plate 5 may be arranged in an arc shape protruding along the direction from the first side portion 51 toward the second side portion 52, which is more conducive to reducing the aerodynamic resistance in the air guide channel 4a, improving the flow stabilization effect, and thus reducing aerodynamic noise.

[0075] In practice, the two side plates 16 of the guide vane 5 can be arranged symmetrically. See [link / reference] for details. Figure 9 As shown.

[0076] For example, at least a portion of the guide plate 5 can be made of porous sound-absorbing material, so that when the airflow passes through the guide plate 5, a certain degree of noise reduction can be achieved through the guide plate 5. In a specific implementation, the entire guide plate 5 can be made of porous sound-absorbing material.

[0077] like Figure 8 As shown, in some embodiments, the number of guide vanes 5 can be multiple, and the multiple guide vanes 5 can be arranged at intervals along the direction from the inlet to the outlet. In this way, the flow can be stabilized multiple times through multiple guide vanes 5, so as to further improve the flow stabilization effect.

[0078] When the air guide box 4 has multiple air guide channels 4a, a guide plate 5 structure can be set in each air guide channel 4a, and the size of the guide plate 5 can be adaptively adjusted according to the size of the air guide channel 4a.

[0079] In one feasible approach, the air guide box 4 can be an independent structure relative to the compressor compartment 1, and can be installed and used as a separate component. In other feasible approaches, when the compressor compartment 1 is located at the bottom of the refrigeration equipment, it can also be directly formed using the foamed insulation material at the bottom of the refrigeration equipment, thereby reducing the number of structural components, making it easier to install quickly, and ensuring the structural stability of the air guide box 4.

[0080] In view of the above-mentioned configuration, this utility model embodiment also provides a refrigeration device, which includes the above-mentioned compressor compartment heat dissipation and noise reduction device.

[0081] For example, the refrigeration device is a refrigerator, and the compressor compartment heat dissipation and noise reduction device is located at the bottom of the refrigerator. In other embodiments, the refrigeration device can also be a freezer, refrigerator, etc., and the compressor compartment heat dissipation and noise reduction device can also be located in other positions.

[0082] Furthermore, such as Figure 1 As shown, the refrigeration equipment includes a housing 10, and a compressor compartment heat dissipation and noise reduction device is installed at the bottom of the housing 10. Correspondingly, an air inlet and an air outlet are provided on the housing 10 at the position corresponding to the ventilation opening 1a. When the compressor compartment heat dissipation and noise reduction device includes an air guide box 4, an air inlet and an air outlet are provided on the housing 10 at the position corresponding to the air guide inlet 41 of the air guide box 4.

[0083] For example, the air inlet and air outlet can be opened on the left and right sides of the housing 10 to realize the air intake and exhaust of the refrigeration equipment on both sides. In other implementations, the air inlet and air outlet can also be opened on the front and rear sides of the housing 10. The specific location can be adjusted according to the position of the compressor compartment heat dissipation and noise reduction device or the position of the air guide box 4.

[0084] The refrigeration equipment provided in this embodiment of the present invention has the same technical effect as the above-mentioned compressor compartment heat dissipation and noise reduction device, so it will not be described again here.

[0085] In some embodiments, a heat dissipation grille is provided on the outer casing 10. The heat dissipation grille is located at a position corresponding to the heat dissipation and noise reduction device of the compressor compartment 1. A plurality of heat dissipation vents are formed on the heat dissipation grille to connect the interior of the outer casing 10 with the outside. The heat dissipation vents extend downward at an angle along the inner side of the outer casing 10 toward the outer side.

[0086] This configuration not only further enhances the heat dissipation and cooling of the compressor compartment 1, but also allows the noise emitted by the compressor compartment 1 to be transmitted through the heat dissipation vents and reflected to the ground, thereby changing the direction of sound radiation and preventing forward propagation, thus improving the user experience.

[0087] It should be noted that the aforementioned heat dissipation vents extend downwards, specifically meaning that when the cooling equipment is placed on the ground, the heat dissipation vents extend towards the ground.

[0088] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
