[0058] Reference below Figure 1-Figure 17 A fan assembly 100 according to an embodiment of the present invention is described.

[0059] Reference below Figure 1-Figure 17 A fan assembly 100 according to an embodiment of the present invention is described.

[0060] like Figure 7-Figure 11 As shown, according to one embodiment of the present invention, the fan assembly 100 includes: a shell 10 and a wind wheel 20, the shell 10 has a receiving space 101, the shell 10 also has a first air outlet duct 102 and a second air outlet duct 103, the first air outlet duct 102 and the second air outlet duct 103 are both connected to the receiving space 101, and the wind wheel 20 is arranged in the receiving space 101.

[0061] Among them, the first air outlet duct 102 and the second air outlet duct 103 are arranged at intervals in the circumferential direction of the wind wheel 20, and in the axial direction of rotation of the wind wheel 20, the first air outlet duct 102 and the second air outlet duct 103 extend to the same side of the wind wheel 20, that is, the air outlet directions of the first air outlet duct 102 and the second air outlet duct 103 are roughly the same. For example, the axial direction of rotation of the wind wheel 20 is the front-to-back direction, and the two air outlet ducts can be one gradually tilted upward from the back to the front to discharge air, and the other gradually tilted downward from the back to the front to discharge air.

[0062] For example, the inlet of the first air outlet duct 102 and the inlet of the second air outlet duct 103 are respectively arranged on the outer circumference of the shell 10, and the inlets of the two air ducts can be staggered in the rotation axis of the wind wheel 20, or the inlets of the two air ducts are located at the same position in the rotation axis of the wind wheel 20, but are arranged at intervals in the circumferential direction of the wind wheel 20; the outlet of the first air outlet duct 102 (i.e., the first air duct outlet 1021) and the outlet of the second air outlet duct 103 (i.e., the second air duct outlet 1031) are located on the same side of the rotation axis of the wind wheel 20, so that the first air outlet duct 102 and the second air outlet duct 103 extend to the same side of the wind wheel 20, so that air can be supplied to the outside from the same side of the wind wheel 20, and the two air ducts are arranged at intervals, so that air can be supplied from different positions, which can not only improve the utilization rate of the air volume and the efficiency of the wind wheel 20, but also improve the uniformity of the air supply.

[0063] When the fan assembly 100 is applied to the storage device 200, air can be supplied from multiple directions of the storage device 200, so that the air supply in the storage device 200 is more uniform, thereby improving the uniformity of the temperature in the storage cavity 501, and can quickly reduce the temperature in the storage cavity 501, thereby improving the cooling effect, which is beneficial to the preservation of food in the storage cavity 501.

[0064] According to the fan assembly 100 of the embodiment of the present invention, by providing two air outlet ducts, and the two air outlet ducts extend to the same side of the wind wheel 20, air can be supplied from different positions, which can not only improve the utilization rate of the air volume and the efficiency of the wind wheel 20, but also improve the uniformity of the air supply and improve the air supply effect.

[0065] In some embodiments, the fan assembly 100 also includes a driving member 30, which is connected to the wind wheel 20 and is used to drive the wind wheel 20 to rotate. Here, the driving member 30 can be arranged in the accommodating space 101 of the shell 10, or can be installed on the outside of the shell 10. The driving shaft of the driving member 30 extends into the accommodating space 101 to connect to the wind wheel 20.

[0066] In some embodiments, the inlet of the first air outlet duct 102 and the inlet of the second air outlet duct 103 are respectively arranged on the outer periphery of the housing 10, and the inlets of the two air ducts are staggered in the rotation axis of the wind wheel 20. Fig. 9 As shown, in the first direction F1 , the inlet of the first air outlet duct 102 is located on one side of the second air outlet duct 103 , thereby facilitating airflow at different positions in the housing 10 to flow out through different air ducts, thereby reducing airflow interference.

[0067] Among them, the inlet of the first air outlet duct 102 here is the opening of the connection between the first air outlet duct 102 and the containing space 101, and the rotation of the wind wheel 20 makes the airflow in the containing space 101 enter the first air outlet duct 102 through the inlet of the first air outlet duct 102, and then flow out through the outlet of the first air outlet duct 102; the inlet of the second air outlet duct 103 here is the opening of the connection between the second air outlet duct 103 and the containing space 101, and the rotation of the wind wheel 20 makes the airflow in the containing space 101 enter the second air outlet duct 103 through the inlet of the second air outlet duct 103, and then flow out through the outlet of the second air outlet duct 103.

[0068] like Fig.11 As shown, in some embodiments, the housing 10 includes a first volute 11 and a second volute 12, and the first volute 11 and the second volute 12 are arranged along the rotation axis of the wind wheel 20 (such as Fig.11 The first volute 11 defines a part of the accommodating space 101, and the first volute 11 has a first air outlet duct 102. The second volute 12 defines another part of the accommodating space 101, and the second volute 12 has a second air outlet duct 103. Thus, the shell 10 forms a double-layer structure with two air outlet ducts. The design of two volutes can, on the one hand, reduce the confusion and loss of air flow, improve the stability and efficiency of air flow, and reduce air supply noise; and can improve the uniformity of air outlet at the air duct outlet and improve the air supply effect; on the other hand, two volutes are used, so that each volute can effectively guide the airflow to the corresponding air outlet duct, reduce the confusion of air flow in the two air outlet ducts, and further improve the air supply effect.

[0069] In some embodiments, the projection of the first volute 11 along the rotation axis of the wind rotor 20 and the projection of the second volute 12 along the rotation axis of the wind rotor 20 are centrally symmetrically arranged about the rotation center of the wind rotor 20, that is, the projections of the first volute 11 and the second volute 12 are centrally symmetrically arranged relative to the rotation axis of the wind rotor 20, and the projection of the first volute 11 can coincide with the projection of the second volute 12 by rotating 180° around the rotation center of the wind rotor 20, thereby making the first volute 11 and the second volute 12 staggered and stacked in the rotation axis of the wind rotor 20, the center lines of the first volute 11 and the second volute 12 both pass through the rotation center of the wind rotor 20, and the first air outlet duct 102 and the second air outlet duct 103 can be relatively arranged on both sides of the wind rotor 20 in the radial direction, thereby facilitating the balance and stability of the structure of the fan assembly 100, facilitating the balance of the airflow, reducing vibration and noise, and improving the efficiency of the wind rotor 20. Improve the wind outlet effect of the wind rotor 20.

[0070] like Fig.11As shown, in some embodiments, in the axial direction of rotation of the wind wheel 20, the thickness dimension of the portion of the wind wheel 20 located in the first volute 11 is H1, and the thickness dimension of the portion of the wind wheel 20 located in the second volute 12 is H2, and H1 is the same as H2, that is, the height of the flow channel in the first volute 11 is the same as the height of the flow channel in the second volute 12, so that the air volume in the two volutes is the same, and the air outlet of the first air duct outlet 1021 and the second air duct outlet 1031 are the same, so that the air supply in all directions is more uniform.

[0071] like Fig.11 As shown, in some embodiments, the shell 10 also includes a partition plate 13, which is arranged in the accommodating space 101, and the partition plate 13 is located between the first volute 11 and the second volute 12, and the partition plate 13 is connected to the connection between the first volute 11 and the second volute 12, which can reduce the mutual interference of the airflow generated by the rotation of the wind wheel 20 in the first volute 11 and the second volute 12, thereby improving the stability of the air supply of the first air outlet duct 102 and the second air outlet duct 103, and at the same time can also improve the structural strength of the shell 10 and improve the service life of the fan assembly 100.

[0072] The partition plate 13 extends along the circumference of the wind wheel 20, and the partition plate 13 can be perpendicular to the rotation axis of the wind wheel 20. The wind wheel 20 and the partition plate 13 are arranged at intervals to ensure that there is a certain movement gap between the partition plate 13 and the wind wheel 20 to ensure that the driving member 30 can drive the wind wheel 20 to rotate.

[0073] like Fig.11 As shown, in some examples, the distance between the wind wheel 20 and the partition plate 13 is d, wherein, since there may be certain vibrations during the rotation of the wind wheel 20, if the distance is too small, it is easy to interfere with the partition plate 13 when the wind wheel 20 rotates; and if the distance is too large, there will be more connections in the circulation of the two volutes, which will cause the airflows in the two volutes to interfere with each other. For this reason, the distance d between the wind wheel 20 and the partition plate 13 is limited to between 2mm-10mm, and d can be any point value of 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or any range value between the two. This can ensure that the operation of the wind wheel 20 does not interfere, and at the same time ensure the independence of the two volute flow channels, thereby improving the stability of air supply of the fan assembly 100.

[0074] like Figure 7 and Figure 8As shown, the first volute 11 and the second volute 12 are integrally formed. The integrally formed structure can provide better structural stability and strength, while simplifying the manufacturing process and reducing the assembly steps, thereby improving production efficiency and reducing costs; and thereby reducing seams or connection points, thereby providing a smoother airflow path, reducing eddies and turbulence, and thereby improving the efficiency and performance of the wind wheel 20.

[0075] like Figure 9-11 As shown, in some embodiments, the first air outlet duct 102 has a first air outlet 1021 , the second air outlet duct 103 has a second air outlet 1031 , and the center lines of the first air outlet 1021 and the second air outlet 1031 are respectively parallel to the rotation axis of the wind wheel 20 .

[0076] By setting the center lines of the two air outlet ducts to be parallel to the rotation axis, it can be ensured that the air sucked in by the wind wheel 20 can be discharged from the two outlets in a balanced manner after being accelerated by the wind wheel 20, which can optimize the airflow path and reduce energy loss, thereby improving the overall efficiency of the wind wheel 20; at the same time, it is beneficial to reduce the vibration and noise of the wind wheel 20.

[0077] When the fan assembly 100 is applied to the storage device 200, the storage cavity 501 of the storage device 200 is located on one side of the fan assembly 100, and the gas in the storage cavity 501 can enter the housing 10 of the fan assembly 100 through the air duct inlet 1041. When the driving member 30 drives the wind wheel 20 to rotate, the wind wheel 20 accelerates the gas entering the housing 10 and re-enters the storage cavity 501 to realize a gas circulation flow channel.

[0078] like Fig.16 As shown, in some embodiments, the first air duct outlet 1021 has a length direction (such as Fig.16 As shown in the second direction F2), in the length direction, the first air outlet duct 102 has a first air duct wall 141 and a second air duct wall 142 arranged relatively, and the angle between the first air duct wall 141 and the second air duct wall 142 is α1, wherein, if α1 is too large, the angle between the two air duct walls is too large, which will cause the air outlet to be too divergent, thereby affecting the air outlet effect, and thus α1 is limited to between 0-45°, and α1 can be any point value among 0, 10°, 15°, 20°, 30°, 40°, 45° or any range value between the two, wherein when α1 is 0, the first air duct wall 141 and the second air duct wall 142 are parallel, thereby avoiding the air outlet of the first air outlet duct 102 from being too divergent and improving the air outlet effect of the first air outlet duct 102.

[0079] like Fig.17 As shown, in some embodiments, the second air duct outlet 1031 has a length direction (such as Fig.17As shown in the second direction F2), in the length direction, the second air outlet duct 103 has a third air duct wall 151 and a fourth air duct wall 152 which are relatively arranged, and the angle between the third air duct wall 151 and the fourth air duct wall 152 is α2, wherein if α2 is too large, the angle between the two air duct walls is too large, which will cause the air outlet to be too divergent, thereby affecting the air outlet effect, and thus α2 is limited to between 0-45°, and α2 can be any point value among 0, 10°, 15°, 20°, 30°, 40°, 45° or any range value between the two, wherein when α2 is 0, the third air duct wall 151 and the fourth air duct wall 152 are parallel, thereby avoiding the air outlet of the second air outlet duct 103 from being too divergent and improving the air outlet effect of the second air outlet duct 103.

[0080] like Figure 13-Figure 17 As shown, in some embodiments, the first air outlet duct 102 and the second air outlet duct 103 are arranged relative to each other to be suitable for supplying air to the storage cavity 501, wherein, along the direction away from the wind wheel 20, the first air outlet duct 102 is suitable for extending obliquely from the top to the bottom of the storage cavity 501, and the second air outlet duct 103 is suitable for extending obliquely from the bottom to the top of the storage cavity 501, thereby making it possible for the storage cavity 501 to have air supply from the top to the bottom and from the bottom to the top, thereby increasing the air volume in the storage cavity 501 and improving the uniformity of the air supply.

[0081] like Fig.16 As shown, in some embodiments, the first air outlet duct 102 has two relatively arranged first air duct walls 141 and second air duct walls 142, and the second air duct wall 142 is away from the top of the storage cavity 501 relative to the first air duct wall 141, wherein the inclination angle of the second air duct wall 142 relative to the horizontal direction is too small, and within a certain air outlet distance, the position where the air is delivered is too high, which will cause the delivered wind to be difficult to extend to the bottom of the storage cavity 501, thereby affecting the air supply effect, resulting in uneven gas in the storage cavity 501, and further affecting the cooling or heating effect; and the inclination angle of the second air duct wall 142 relative to the horizontal direction is too large, which will cause part of the air volume to flow to the outside of the storage cavity 501, resulting in waste of air volume and reducing the air supply effect of the fan assembly 100.

[0082] To this end, the angle α3 between the second air duct wall 142 and the horizontal direction is limited to between 20° and 75°. α3 can be any point value among 20°, 30°, 40°, 50°, 60°, 70°, 75° or a range value between any two of them. This can not only increase the air supply range, but also avoid waste of air volume and improve the air supply effect.

[0083] like Fig.17As shown, in some embodiments, the second air outlet duct 103 has two relatively arranged third air duct walls 151 and fourth air duct walls 152, and the third air duct wall 151 is away from the bottom of the storage cavity 501 relative to the fourth air duct wall 152, wherein the inclination angle of the third air duct wall 151 relative to the horizontal direction is too small, and within a certain air outlet distance, the position where the air is delivered is too low, which will cause the delivered wind to be difficult to extend to the top of the storage cavity 501, thereby affecting the air supply effect, resulting in uneven gas in the storage cavity 501, and further affecting the cooling or heating effect; and the inclination angle of the third air duct wall 151 relative to the horizontal direction is too large, which will cause part of the air volume to flow to the outside of the storage cavity 501, resulting in waste of air volume and reducing the air supply effect of the fan assembly 100.

[0084] To this end, the angle α4 between the third air duct wall 151 and the horizontal direction is limited to between 20° and 75°. α4 can be any point value among 20°, 30°, 40°, 50°, 60°, 70°, 75°, or a range value between any two of them. This can not only increase the air supply range, but also avoid waste of air volume and improve the air supply effect.

[0085] like Figure 7-Figure 9 As shown, in some embodiments, the first air outlet duct 102 has a first air duct outlet 1021, the second air outlet duct 103 has a second air duct outlet 1031, the shell 10 has an air duct inlet 1041, the air duct inlet 1041 is connected to the accommodating space 101, and in the axial direction of rotation of the wind wheel 20, the air duct inlet 1041, the first air duct outlet 1021 and the second air duct outlet 1031 are located on the same side of the wind wheel 20, wherein the air inlet direction of the first air outlet duct 102 is opposite to the air inlet direction of the air duct inlet 1041; the air outlet direction of the second air outlet duct 103 is opposite to the air inlet direction of the air duct inlet 1041, so that the fan assembly 100 can take in air from one side, and after being accelerated by the wind wheel 20, send air outward from the same side, and form two streams of wind to one side of the fan assembly 100.

[0086] In addition, if Figure 8 As shown, the shell 10 also includes a bottom plate 16, which is connected to the side of the second volute 12 facing away from the first volute 11, and the bottom plate 16 is sealed with the second volute 12. The drive member 30 can be installed on the bottom plate 16. The side of the first volute 11 facing away from the second volute 12 has an air duct inlet 1041, thereby forming a relatively closed space in the shell 10. The gas can enter the shell 10 from the air duct inlet 1041, and flow out from the two air duct outlets respectively after being accelerated by the wind wheel 20.

[0087] The storage device 200 according to the embodiment of the present invention includes the fan assembly 100 according to the embodiment of the present invention. By adopting the above-mentioned fan assembly 100, air can be supplied to the storage cavity 501 of the storage device 200 from different positions, which can not only improve the utilization rate of the air volume and the efficiency of the wind wheel 20, but also improve the uniformity of the air supply and the air supply effect, thereby improving the cooling and heating effects of the storage device 200.

[0088] like Figure 1-Figure 17 As shown, the storage device 200 according to the embodiment of the present invention includes: a storage box 50 and a fan assembly 100, the storage box 50 has a first side wall 51 and a second side wall 52, the first side wall 51 and the second side wall 52 can be arranged relatively, the storage box 50 defines a storage cavity 501, the first side wall 51 is provided with a first air inlet 5021, the second side wall 52 is provided with a second air inlet 5022, the first air inlet 5021 and the second air inlet 5022 are respectively connected to the storage cavity 501, that is, the internal space of the storage box 50 forms a storage cavity, which can store food and other items, air inlets are provided on both side walls of the storage box 50, the air inlets can allow cold air to enter the storage cavity 501, and a heat exchange plate 411 is provided on the outer side of the storage box 50.

[0089] The fan assembly 100 includes a wind wheel 20, and the fan assembly 100 has a first air duct outlet 1021 and a second air duct outlet 1031, wherein the first air duct outlet 1021 is located between the first side wall 51 of the storage box 50 and the heat exchange plate 411, and the second air duct outlet 1031 is located between the second side wall 52 of the storage box 50 and the heat exchange plate 411, the first air duct outlet 1021 is connected to the storage cavity 501 through the first air inlet 5021, and the second air duct outlet 1031 is connected to the storage cavity 501 through the second air inlet 5022.

[0090] Therefore, part of the wind blown out by the wind wheel 20 can enter the storage cavity 501 through the first air duct outlet 1021 and the first air inlet 5021 on the first side wall 51, and the other part can enter the storage cavity 501 through the second air duct outlet 1031 and the second air inlet 5022 on the second side wall 52. In this way, air can be supplied from both sides of the storage room, which can not only improve the utilization rate of the air volume and the efficiency of the wind wheel 20, but also improve the uniformity of air supply, which is beneficial to keep the food in the storage cavity 501 fresh.

[0091] According to the storage device 200 of the embodiment of the present invention, by arranging air inlets on the two side walls of the storage box 50 and adopting the fan assembly 100 with two air duct outlets, air can be supplied to the storage cavity 501 from different positions, which can not only improve the utilization rate of the air volume and the efficiency of the fan assembly 100, but also improve the air supply effect of the fan assembly 100 and the uniformity of the air volume in the storage cavity 501, thereby improving the cooling and heating effects of the storage device 200.

[0092] like Figure 1 and Figure 2 As shown, in some embodiments, the storage device 200 also includes a heat exchange element 60, which can be an evaporator or a condenser for cooling or heating. The heat exchange element 60 can also be a liquid cooling pipe, a liquid cooling plate, and the liquid cooling pipe or liquid cooling plate is connected to a cooling liquid pool, etc.

[0093] The fan assembly 100 has a wind wheel 20. In the rotation axis direction of the wind wheel 20, the first air inlet 5021 and the first air duct outlet 1021 are arranged at intervals, the second air inlet 5022 and the second air duct outlet 1031 are arranged at intervals, and at least a part of the heat exchange element 60 is located between the first air duct outlet 1021 and the first air inlet 5021, and at least a part of the heat exchange element 60 is located between the second air duct outlet 1031 and the second air inlet 5022, that is, the air duct outlet is connected to the storage box 5. A certain distance is designed between the air inlets 0, thereby forming a flow channel between the first side wall 51 and the heat exchange plate 411, and between the second side wall 52 and the heat exchange plate 411. A part of the heat exchange element 60 is located at the flow channel, so that the wind sent by the fan assembly 100 can pass through the heat exchange element 60, that is, this place is a heat exchange area, and the wind entering the storage cavity 501 is cold wind after heat exchange by the heat exchange element 60, so that the temperature in the storage cavity 501 can be effectively reduced and adjusted, and the cooling and heating effects can be improved.

[0094] Since at least a portion of the heat exchange element 60 is located between the second air duct outlet 1031 and the second air inlet 5022, and at least a portion is located between the first air duct outlet 1021 and the first air inlet 5021, it is ensured that the gas flowing out of the first air duct outlet 1021 and the gas flowing out of the second air duct outlet 1031 can both pass through the heat exchange element 60, and the gas in the flow channel can fully contact and exchange heat with the heat exchange element 60, thereby further improving the cooling and heating effects.

[0095] like Figure 1 As shown, in some embodiments, the fan assembly 100 is disposed between the heat exchange plate 411 and the storage box 50, thereby improving space utilization, and the heat exchange element 60 is disposed on the outside of the heat exchange plate 411. The heat exchange element 60 does not occupy the space inside the heat exchange plate 411, thereby increasing the air supply space.

[0096] In some examples, the heat exchange element 60 is an evaporator, and the evaporator flat tubes are arranged on the outer surface of the heat exchange plate 411. The evaporator flat tubes are connected to the evaporator header, and the evaporator header is connected to the evaporator joint. The evaporator joint can be connected to an expansion valve, a compressor, etc.

[0097] like Figure 12-14As shown, in some embodiments, the first air inlet 5021 includes multiple air inlet holes, and the second air inlet 5022 includes multiple air inlet holes, each of which is in an elongated shape, such as an oblong or rectangular shape. By providing multiple elongated air inlet holes, the wind flow area can be increased and the amount of air entering the storage cavity 501 can be increased. In addition, by adopting a design with multiple small holes, the uniformity of the air supply can be improved and the wind speed of the air supply can be increased to a certain extent, thereby quickly reducing the temperature in the storage cavity 501, improving the cooling effect, and improving the performance of the storage device 200.

[0098] like Figure 6 , Figure 12-14 As shown, in some embodiments, the side of the first side wall 51 facing away from the second side wall 52 has two first sealing ribs 511, and the first sealing ribs 511 extend in a direction close to the corresponding heat exchange plate 411, and the first air inlet 5021 and the first air duct outlet 1021 on the first side wall 51 are located between the two first sealing ribs 511, thereby improving the sealing of the flow channel between the first side wall 51 and the heat exchange plate 411 to a certain extent, so that the wind flowing out of the first air duct outlet 1021 can be retained at the first air inlet 5021 of the first side wall 51 as much as possible, which can not only reduce the loss of air volume and improve the utilization rate of air volume, but also allow the wind flowing out of the first air duct outlet 1021 to be retained in the first air inlet 5021 as soon as possible, thereby improving the air supply efficiency.

[0099] like Figure 6 As shown, in some examples, the first sealing rib 511 and the heat exchange plate 411 are arranged at intervals, and the shortest distance between the first sealing rib 511 and the heat exchange plate 411 is a, that is, the gap distance between the edge of the first sealing rib 511 and the heat exchange plate 411 is a, wherein, if a is too small, the storage box 50 is prone to interference when being assembled with the heat exchange plate 411, and if a is too large, the gap there is too large to form a relatively closed space, for this reason, a can be limited to between 1mm-6mm, and a can be any point value of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm or a range value between any two of them, thereby taking into account both the flow channel sealing and the assembly process.

[0100] like Figure 6As shown, in some embodiments, the side of the second side wall 52 facing away from the first side wall 51 has two second sealing ribs 521, and the second sealing ribs 521 extend in a direction close to the corresponding heat exchange plate 411, and the second air inlet 5022 and the second air duct outlet 1031 on the second side wall 52 are located between the two second sealing ribs 521, thereby improving the closing property of the flow channel between the second side wall 52 and the heat exchange plate 411 to a certain extent, so that the wind flowing out of the second air duct outlet 1031 can be retained at the second air inlet 5022 of the second side wall 52 as much as possible, which can reduce the loss of air volume and improve the utilization rate of air volume, and can also make the wind flowing out of the second air duct outlet 1031 be retained in the second air inlet 5022 as soon as possible, thereby improving the air supply efficiency.

[0101] like Figure 6 As shown, in some examples, the second sealing rib 521 is spaced apart from the inner wall surface of the heat exchange plate 411, and the shortest distance between the second sealing rib 521 and the heat exchange plate 411 is b, that is, the gap distance between the edge of the second sealing rib 521 and the heat exchange plate 411 is b, wherein, if b is too small, interference is likely to occur during assembly of the storage box 50 and the heat exchange plate 411, and if b is too large, the gap there is too large to form a relatively closed space, for this reason, b can be limited to between 1 mm and 6 mm, and b can be any point value among 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, or a range value between any two of them, thereby taking into account both the flow channel sealing and the assembly process.

[0102] like Figure 4-Figure 6 , Fig.12 As shown, in some embodiments, the storage box 50 further has a third side wall 53, the third side wall 53 is connected between the first side wall 51 and the second side wall 52, the third side wall 53 has an air outlet 503, the wind wheel 20 is arranged between the third side wall 53 and the heat exchange plate 411, the fan assembly 100 has an air duct inlet 1041, and the air duct inlet 1041 is located on a side of the wind wheel 20 close to the air outlet 503, so that the air outlet 503 is connected to the air duct inlet 1041, and the air in the storage cavity 501 flows from the air outlet 503 to the air duct inlet 1041, and the air in the storage cavity 501 flows from the air outlet 503 to the air duct inlet 1041. The incoming wind flows through the wind wheel 20 and is divided into two parts. One part flows through the first volute 11, is sent out from the first air duct outlet 1021, passes through the two first sealing ribs 511 on the outer wall of the storage box 50 and the space flow channel between the heat exchange plate 411 to reach the first air inlet 5021. The other part enters the second volute 12, is sent out from the second air duct outlet 1031, passes through the two second sealing ribs 521 on the outer wall of the storage box 50 and the space flow channel between the heat exchange plate 411 to reach the second air inlet 5022, and reaches the air outlet 503 after circulating in the storage cavity 501, forming a complete cycle.

[0103] like Figure 5As shown, in some embodiments, the center of the air outlet 503 and the center of the air duct inlet 1041 are located on the rotation axis of the wind wheel 20, so that the airflow can enter the air duct directly and smoothly from the air outlet 503, reducing the loss and resistance of the airflow and improving the overall airflow efficiency; and the turbulence and eddy current of the airflow can be reduced, thereby reducing noise; the overall structural layout is more compact.

[0104] like Figure 7-Figure 11 As shown, in some embodiments, the fan assembly 100 includes a first volute 11 and a second volute 12, and the first volute 11 and the second volute 12 are arranged along the rotation axis of the wind wheel 20, the first volute 11 defines a part of the accommodating space 101, and the second volute 12 defines another part of the accommodating space 101, and the wind wheel 20 is arranged in the accommodating space 101, wherein a part of the first volute 11 extends between the first side wall 51 and the heat exchange plate 411, and the first volute 11 has a first air duct outlet 1021, and a part of the second volute 12 extends between the second side wall 52 and the heat exchange plate 411, and the second volute 12 has a second air duct outlet 1031.

[0105] The fan assembly 100 thus forms a double-layer volute structure, which can not only reduce the confusion and loss of the air flow, improve the stability and efficiency of the air flow, and reduce the air supply noise; it can also guide the air flow to the corresponding air duct outlet, reduce the air flow confusion at the two air duct outlets, further improve the air supply effect, and the overall structure is more compact and reasonable.

[0106] A heat exchange element 60 is provided on the heat exchange plate 411. In the air supply direction, the heat exchange element 60 is located between the air duct outlet and the air inlet, so that the gas flowing out of the air duct outlet is cooled or heated and then passed into the storage cavity 501. The double-layer volute design not only ensures the cooling and heating effects, but also makes the storage cavity 501 receive wind evenly. When air is supplied on both sides of the storage cavity 501, the cold air can flow more evenly into the storage cavity 501, thereby quickly reducing the temperature of the inner wall of the storage cavity 501 and achieving a good cooling effect.

[0107] In some embodiments, a sliding portion 54 is provided at the bottom of the storage box 50, and the storage device also has a bottom plate 412, and the bottom plate 412 is provided with a guide portion 43. The sliding portion 54 slidably cooperates with the guide portion 43 so that the storage box 50 can be pulled out, that is, the storage box 50 forms a drawer-type storage structure, which is convenient for storage and retrieval.

[0108] In some embodiments, the storage device also includes a cover body 42, and the top of the storage cavity 501 is open. The cover body 42 is arranged on the top of the storage cavity 501, wherein the cover body 42 is movably connected to the heat exchange plate 411, or the cover body 42 is movably connected to the storage box 50, thereby the storage cavity 501 can be opened in a flip-cover manner, which is flexible to use and meets the use requirements of special spaces.

[0109] like Figure 2 and Figure 6 As shown, in some embodiments, the storage device 200 has a bottom plate 412, a guide portion 43 is provided on the bottom plate 412, a storage box 50 is installed on the bottom plate 412 through a sliding portion 54, a cover body 42 is provided on the heat exchange plate 411, and the cover body 42 is connected to the heat exchange plate 411. The connection here can be a fixed connection, a detachable connection, or a rotating matching connection. Therefore, the storage device can both flip open the storage cavity and pull open the storage cavity. Therefore, when applied to special scenarios, such as in the car, it is convenient for the driver and co-driver to flip the cover, and it is also convenient for the rear passengers to pull it out.
