[0042] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0043] The following is for reference. Figures 1-10 This application describes an air duct module and a refrigeration device according to embodiments thereof.

[0044] Please see Figure 1 This application provides a refrigeration device 1000, which includes a housing 100, a door, and an air duct module 200.

[0045] The refrigeration equipment 1000 provided in this application embodiment can be a sideboard, refrigerator, freezer, or wine cabinet, etc., and is not specifically limited.

[0046] The housing 100 has a first cooling chamber 101 and a second cooling chamber 102 located above the first cooling chamber 101.

[0047] Please see Figure 1 The enclosure 100 may include an outer shell, an insulation layer, and an inner liner 110. The outer shell may be made of metal (such as steel plate), with a painted surface to prevent rust and for aesthetic purposes. The insulation layer, located between the inner shell and the inner liner 110, may be polyurethane foam, providing excellent thermal insulation to effectively prevent heat exchange and maintain a stable internal temperature. The inner liner 110, being the part that directly contacts the stored items, is generally made of ABS plastic or stainless steel, requiring non-toxicity and ease of cleaning. The interior of the inner liner 110 forms a cooling cavity for accommodating the stored items.

[0048] The cabinet 100 includes a first refrigeration chamber 101 and a second refrigeration chamber 102, with the second refrigeration chamber 102 located above the first refrigeration chamber 101. The temperatures of the first refrigeration chamber 101 and the second refrigeration chamber 102 can be different. For example, the refrigeration device 1000 can be a vertical sideboard, where the first refrigeration chamber 101 can be a freezing chamber and the second refrigeration chamber 102 can be a refrigeration chamber, allowing the temperature of the first refrigeration chamber 101 to be lower than that of the second refrigeration chamber 102, thus achieving different storage functions. The different temperature ranges of the refrigeration chamber and the freezing chamber are adjusted by a temperature control device located inside or outside the cabinet 100.

[0049] The door also comprises a three-layer structure: an outer shell, insulation material, and an inner lining, ensuring excellent sealing and insulation performance. The door is connected to the enclosure 100 via hinges, allowing for smooth opening and closing. The door can be a single or double door; a single door can also have an adjustable opening direction. Sealing strips can be installed along the edges of the door, fitting snugly against the enclosure 100 to prevent cold air leakage and seal the refrigeration chamber.

[0050] The air duct module 200 is installed in the first cooling chamber 101. It should be noted that, in this embodiment, the inner liner 110 is the inner liner 110 of the first cooling chamber 101.

[0051] The specific structure of the air duct module 200 can refer to the following technical solution:

[0052] Please see Figure 1 , Figure 2 and Figure 3 This application embodiment also provides an air duct module 200, which includes a housing 210, a volute 230, and a fan 240.

[0053] The housing 210 has a cavity for gas flow.

[0054] The housing 210 is installed inside the inner liner 110 of the cabinet 100 and connected to the rear wall 112 of the inner liner 110. Taking the refrigeration equipment 1000 as a vertical sideboard as an example, the refrigeration equipment 1000 has a door on the front side, the front side of the inner liner 110 is open, and the rear wall 112 of the inner liner 110 is the bottom in the depth direction of the refrigeration cavity. The housing 210 is installed inside the refrigeration cavity defined by the inner liner 110. The housing 210 has a cavity for gas flow so that the cavity can be part of the air duct. The cavity is also used to accommodate devices and pipes such as the evaporator 220, fan 240, volute 230 and return air pipe. The housing 210 can be made of metal material to have good mechanical strength and corrosion resistance, or it can be made of composite material to have good corrosion resistance, light weight and good heat insulation. This can not only reduce the weight of the entire air duct module 200, but also improve the heat insulation effect and reduce energy consumption.

[0055] The housing 210 is installed in the refrigeration chamber in the form of a plate extending in the front-to-back and height directions, so as to minimize the occupancy of the refrigeration equipment 1000 thickness.

[0056] Please see Figure 4 and Figure 5The volute 230 is disposed inside the cavity, and the fan 240 is disposed inside the volute 230. The volute 230 has a first air outlet 231 and a second air outlet 232. The first air outlet 231 is connected to the rear part of the housing 210 and is used to supply air to the first cooling chamber 101. The width of the first air outlet 231 in the thickness direction of the housing 210 gradually widens along the air outlet direction. The second air outlet 232 of the volute 230 is connected to the upper part of the housing 210 and is used to supply air to the second cooling chamber 102.

[0057] A wind cavity is formed within the volute 230 to guide airflow, allowing it to smoothly enter the duct system from the outlet of the fan 240 and circulate within the system. This reduces airflow turbulence and resistance, improving airflow stability. By fixing the fan 240 within the volute 230, stable support is provided, and the airflow generated by the fan 240 generates higher air pressure within the volute 230, thereby enhancing the airflow's pushing capacity and ensuring it reaches the target area smoothly. This also protects the fan 240 and reduces noise.

[0058] The volute 230 is provided with a first air outlet 231 and a second air outlet 232 facing different directions. The first air outlet 231 is connected to the rear part of the housing 210, that is, the air outlet direction of the first air outlet 231 is towards the rear wall 112 of the refrigeration chamber where it is located. Taking the housing 210 installed in the first refrigeration chamber 101 as an example, the first air outlet 231 is set towards the rear wall 112 of the first refrigeration chamber 101 to deliver cold air into the first refrigeration chamber 101. The width of the first air outlet 231 in the thickness direction of the housing 210 gradually increases along the air outlet direction, so that the first air outlet 231 is flared in the air outlet direction. On the one hand, this can reduce the air supply resistance and reduce the air volume loss. On the other hand, the storage space of the first cooling cavity 101 is located on one side of the thickness direction of the housing 210. Therefore, it is necessary to guide the cold air to one side of the thickness direction of the housing 210, that is, the left or right side of the housing 210. Since the first air outlet 231 faces the rear side of the housing 210, by making the first air outlet 231 flared, it is convenient for the airflow to flow to the left or right, reducing the influence of turbulence and improving the air outlet efficiency and air outlet stability.

[0059] The second air outlet 232 is connected to the upper part of the housing 210, that is, the top of the housing 210 in the height direction, to supply air to the second cooling chamber 102 located in the upper part of the housing 210. This allows the air volume output by the fan 240 to be directly distributed to the other cooling chamber through the second air outlet 232. By directly setting air outlets facing different directions on the volute 230, the bending and turning of the air outlet position are reduced, the wind resistance is reduced, and the air outlet efficiency of the fan 240 is greatly improved. The overall air volume is high, the energy consumption is lower, and the performance and energy efficiency ratio of the refrigeration equipment 1000 are improved.

[0060] According to the air duct module 200 provided in the embodiments of this application, by directly setting a first air outlet 231 and a second air outlet 232 facing different directions on the volute 230, the air force output by the fan 240 is directly distributed to the two cooling chambers in two directions, resulting in small air volume loss. Furthermore, the first air outlet 231 is flared to reduce air supply resistance, further reducing air volume loss and greatly improving the air output efficiency of the fan 240. The air volume is distributed to the two cooling chambers to cool the two cooling chambers simultaneously, resulting in high overall air volume and lower energy consumption.

[0061] It is understood that the beneficial effects of the refrigeration equipment 1000 provided in the embodiments of this application are the same as the beneficial effects of the air duct module 200 provided in the embodiments of this application, and will not be repeated here.

[0062] Please see Figure 6 , Figure 7 and Figure 8 According to some embodiments of this application, the housing 210 may include a first side plate 211 and a second side plate 212 spaced apart from each other, and the volute 230 may be installed on the first side plate 211 and spaced apart from the second side plate 212.

[0063] The housing 210 may include a first side plate 211 and a second side plate 212 spaced apart from each other, the first side plate 211 and the second side plate 212 being distributed along the thickness direction of the housing 210.

[0064] By mounting the volute 230 on the first side plate 211 in the thickness direction of the housing 210, the larger area of ​​the first side plate 211 ensures the installation dimensions of the volute 230, improves the stability of the installation structure, and allows for the use of larger volutes 230, facilitating flow channel design. Furthermore, the volute 230 and the second side plate 212 are spaced apart, providing a flow path for the airflow within the cavity. This reduces turbulence and resistance within the housing 210, improves airflow stability and uniformity, and reduces the thickness of the volute 230, resulting in a more compact structure for the air duct module 200, saving installation space and facilitating assembly.

[0065] Please see Figure 4 According to some embodiments of this application, the volute 230 can be covered by the first side plate 211 to form a wind cavity for fixing the fan 240.

[0066] The volute 230 is open on one side facing the first side plate 211. The open end of the volute 230 covers and is fixed to the first side plate 211, so that the first side plate 211 and the volute 230 together form a wind cavity. The first side plate 211 serves as a side wall of the wind cavity, thereby simplifying the structure of the volute 230, reducing manufacturing costs and complexity, and ensuring smooth airflow.

[0067] Furthermore, the volute 230 is open at one end, which facilitates the fixed installation of the fan 240 inside the volute 230, further reducing production costs.

[0068] Please see Figure 8 According to some embodiments of this application, the side wall of the first air outlet 231 near the second side plate 212 can be inclined in the direction of air outlet towards the second side plate 212.

[0069] Because the volute 230 is mounted on the first side plate 211, one sidewall of the first air outlet 231 of the volute 230 is on the first side plate 211. Furthermore, because the volute 230 is spaced apart from the second side plate 212, the air inlet of the first air outlet 231 is also spaced apart from the second side plate 212. Consequently, the projection of the air inlet of the first air outlet 231 onto the rear plate 214, which has the air duct 2141, in the front-rear direction is biased towards the side closer to the first side plate 211.

[0070] By setting the sidewall of the first air outlet 231 near the second side plate 212 to be inclined towards the second side plate 212, the first air outlet 231 is made into a funnel shape. The projection of the air outlet end of the first air outlet 231 onto the rear plate 214 with the air supply duct 2141 in the front-to-back direction is relatively centered. This ensures that the cool air entering the air supply duct 2141 from the first air outlet 231 can be relatively evenly distributed to both sides of the air supply duct 2141, guiding the airflow to flow more smoothly, reducing turbulence at the air outlet, and improving the stability and uniformity of the airflow. With air supply outlets 2144 on both sides of the air supply duct 2141, the airflow from the air supply outlets 2144 distributed on both sides can be more uniform and easier to adjust.

[0071] Please see Figure 6 and Figure 8 According to some embodiments of this application, the volute 230 has an air inlet 233, which may be located on the side of the volute 230 near the second side plate 212.

[0072] The volute 230 and the second side plate 212 are spaced apart to form a gap for gas flow, and the path is unobstructed with a large flow area. By setting the air inlet 233 of the volute 230 on the side close to the second side plate 212, the cold air in the cavity can quickly enter the air inlet 233 and be blown out by the first air outlet 231 and the second air outlet 232 under the action of the fan 240.

[0073] For example, the air inlet 233 can be circular, and the rotation axis of the impeller of the fan 240 is coaxial with the air inlet 233. When the impeller rotates, a negative pressure is generated in the middle of the fan 240 to draw air from the cavity into the volute 230 through the air inlet 233. The air then flows outwards under the rotation of the impeller, allowing the cool air to flow out through the first air outlet 231 on the rear side and the second air outlet 232 on the upper side. This side-intake and rear / top-outtake configuration results in a smoother flow path and reduced flow resistance.

[0074] According to some embodiments of this application, the flow area of ​​the second air outlet 232 can be 1.5 to 3 times the flow area of ​​the first air outlet 231.

[0075] The flow area of ​​the second air outlet 232 can be larger than that of the first air outlet 231. Because the housing 210 is located inside the first cooling chamber 101, the volute 230 is closer to the first cooling chamber 101. The distance between the first air outlet 231 and the air outlet 2144 in the first cooling chamber 101 is shorter. The distance between the second air outlet 232 and the air outlet 2144 in the second cooling chamber 102 is larger, resulting in greater flow resistance. By setting the flow area of ​​the second air outlet 232 to be larger than that of the first air outlet 231, the flow resistance of the second air outlet 232 can be reduced.

[0076] The flow area of ​​the second air outlet 232 can be 1.5 to 3 times the flow area of ​​the first air outlet 231. For example, the flow area of ​​the second air outlet 232 can be 1.5 times, 2 times, 2.5 times, 2.7 times, 3 times or other multiples between 1.5 times and 3 times the flow area of ​​the first air outlet 231, without specific limitation.

[0077] Please see Figure 5 According to some embodiments of this application, a volute tongue 234 may be provided between the first air outlet 231 and the second air outlet 232, and the volute tongue 234 may be located on the side of the first air outlet 231 near the second air outlet 232.

[0078] The volute tongue 234 guides the airflow within the air cavity, optimizing the airflow path, reducing energy loss, minimizing turbulence and vortices between the two air outlets, and improving airflow stability and efficiency. It also ensures a more uniform airflow distribution between the first air outlet 231 and the second air outlet 232, reducing excessive local stress and enhancing the structural stability of the volute 230.

[0079] Specifically, the second air outlet 232 is located at the upper part of the volute 230, the first air outlet 231 is located at the rear part of the volute 230, and the volute tongue 234 is located on the upper side of the first air outlet 231. When the air generated by the fan 240 passes through the volute tongue 234, the speed increases, thereby increasing the pressure of the air volume at the first air outlet 231, increasing the flow rate at the air outlet, reducing losses, improving the cooling speed of the refrigeration equipment 1000, increasing the efficiency of the fan 240, and reducing energy consumption.

[0080] Please see Figure 5 According to some embodiments of this application, the first air outlet 231 and the second air outlet 232 are both directly opposite to the rotation axis of the fan 240.

[0081] The rotation axis of the fan 240 is directly opposite to the first air outlet 231 in the air outlet direction and directly opposite to the second air outlet 232 in the air outlet direction. The fan 240 is close to both the first air outlet 231 and the second air outlet 232. This arrangement shortens the distance between the fan 240 and the air outlet and greatly reduces the loss of air volume output by the fan 240 in the volute 230. It also reduces the resistance of airflow when entering and exiting the volute 230, reduces the energy loss of airflow when passing through the air outlet, improves the energy efficiency of the fan 240, and increases the total air volume output.

[0082] Please see Figure 6 , Figure 8 and Figure 9 According to some embodiments of this application, the housing 210 also includes a rear plate 214, the rear plate 214 is provided with an air supply duct 2141 extending in the height direction, the first air outlet 231 is connected to the front side of the air supply duct 2141, and the side of the air supply duct 2141 is provided with an air outlet 2144 extending in the side direction.

[0083] The housing 210 may further include a front plate 213 and a rear plate 214. The rear plate 214 is used to connect to the rear wall 112. The front plate 213 is located on the side closer to the door. The first side plate 211 and the second side plate 212 are distributed in the left-right direction. The left and right ends of the front plate 213 are respectively connected to the front ends of the first side plate 211 and the second side plate 212. The left and right ends of the rear plate 214 are respectively connected to the rear ends of the first side plate 211 and the second side plate 212, so as to enclose and form a cavity for accommodating devices such as the evaporator 220, the fan 240, and the volute 230. It should be noted that the orientation of the first side plate 211 and the second side plate 212 in the left-right direction is not limited in this application. The first side plate 211 may be located on the left and the second side plate 212 may be located on the right; or the first side plate 211 may be located on the right and the second side plate 212 may be located on the left.

[0084] An air duct 2141 extending along the height direction may be provided inside the rear panel 214. An air outlet 2144 for supplying air to the first cooling chamber 101 may be provided on the side of the air duct 2141. A first air outlet 231 is connected to the front of the air duct 2141, so that the air blown out of the first air outlet 231 first enters the air duct 2141 and flows in the height direction, and is then blown into the first cooling chamber 101 through the air outlet 2144 located on the side of the air duct 2141, thus achieving cooling of the first cooling chamber 101. Because the air duct 2141 is located on the rear panel 214, that is, near the rear wall 112 of the inner liner 110, by providing the air outlet 2144 extending laterally, when the air outlet 2144 is located at a corner of the first cooling chamber 101, air can be better supplied to the first cooling chamber 101.

[0085] The air outlets 2144 can be provided in multiple locations distributed along the height direction to deliver air to various positions in the first cooling chamber 101 along the height direction, making the distribution of cold air more uniform, improving the temperature uniformity within the first cooling chamber 101, reducing energy consumption, and improving the quality of stored items. The air volume of the multiple air outlets 2144 distributed along the height direction can be the same or different, without specific limitations.

[0086] For example, the air volume of multiple air outlets 2144 can be different in order to control the cooling capacity of each location in a targeted manner. By setting the air volume of the upper air outlet 2144 to be the largest, the principle of cold air sinking and hot air rising is used to ensure the temperature of the upper part of the cooling cavity is stable, reduce condensation, and ensure the stability and uniformity of the temperature of the entire cooling cavity by a large amount of cold air falling.

[0087] Please see Figure 10 According to some embodiments of this application, the housing 210 is disposed in the middle of the first cooling cavity 101 to divide the first cooling cavity 101 into a first chamber 120 and a second chamber 130. Air outlets 2144 corresponding to the first chamber 120 and the second chamber 130 are respectively provided on both sides of the housing 210, and the air outlets 2144 are connected to the first air outlet 231.

[0088] The housing 210 is disposed in the middle of the first cooling chamber 101 as a partition. Taking the housing 210 disposed in the middle of the width direction of the first cooling chamber 101 as an example, the housing 210 can divide the first cooling chamber 101 along the width direction to form a first chamber 120 and a second chamber 130 that are spaced apart from each other. Multiple air outlets 2144 corresponding to the first chamber 120 and the second chamber 130 are respectively provided on both sides of the housing 210 to supply air to the first chamber 120 and the second chamber 130, so that the first chamber 120 and the second chamber 130 can be cooled simultaneously. The temperature of the first chamber 120 and the second chamber 130 can be controlled by controlling the air volume of the air outlets 2144 on both sides. The temperatures of the first chamber 120 and the second chamber 130 can be the same or different, without specific limitation.

[0089] Multiple air outlets 2144 distributed along the height direction can be provided on both sides of the air supply duct 2141. The multiple air outlets 2144 on both sides can be arranged one-to-one along the height direction to facilitate the distribution of air volume.
