[0058] Next, reference is made to Figures 1 - 17 Describe the fan assembly 100 according to an embodiment of the present utility model.
[0059] Next, reference is made to Figures 1 - 17 Describe the fan assembly 100 according to an embodiment of the present utility model.
[0060] As Figures 7 - 11 shown, according to an embodiment of the present utility model, the fan assembly 100 includes: a housing 10 and a wind wheel 20. The housing 10 has an accommodation space 101. The housing 10 further has a first air outlet duct 102 and a second air outlet duct 103. Both the first air outlet duct 102 and the second air outlet duct 103 communicate with the accommodation space 101. The wind wheel 20 is disposed in the accommodation space 101.
[0061] Wherein, 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. In the axial direction of the rotation axis 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 to say, the air outlet directions of the first air outlet duct 102 and the second air outlet duct 103 are substantially the same. For example, if the axial direction of the rotation of the wind wheel 20 is the front-rear direction, one of the two air outlet ducts can gradually incline upward from the rear to the front for air outlet, and the other can gradually incline downward from the rear to the front for air outlet.
[0062] For example, the inlets of the first air outlet duct 102 and the second air outlet duct 103 are respectively arranged on the outer periphery of the housing 10. The inlets of the two ducts can be arranged in a staggered manner in the axial direction of the rotation axis of the impeller 20, or the inlets of the two ducts are located at the same position in the axial direction of the rotation axis of the impeller 20, but are arranged at intervals in the circumferential direction of the impeller 20. The outlet of the first air outlet duct 102 (i.e., the first duct outlet 1021) and the outlet of the second air outlet duct 103 (i.e., the second duct outlet 1031) are located on the same side in the axial direction of the rotation axis of the impeller 20. Thus, the first air outlet duct 102 and the second air outlet duct 103 extend to the same side of the impeller 20, so that air can be sent out from the same side of the impeller 20, and the two ducts are arranged at intervals, so that air can be sent from different positions, which can not only improve the utilization rate of the air volume, improve the efficiency of the impeller 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 sent from multiple directions of the storage device 200, making the air supply in the storage device 200 more uniform, thereby improving the uniformity of the temperature in the storage cavity 501, quickly reducing the temperature in the storage cavity 501, improving the cooling effect, and being beneficial to food preservation in the storage cavity 501, etc.
[0064] According to the fan assembly 100 of the embodiment of the present utility model, by providing two air outlet ducts and extending the two air outlet ducts to the same side of the impeller 20, air can be sent from different positions, which can not only improve the utilization rate of the air volume, improve the efficiency of the impeller 20, but also improve the uniformity of the air supply and improve the air supply effect.
[0065] In some embodiments, the fan assembly 100 further includes a driving member 30. The driving member 30 is connected to the impeller 20 and is used to drive the impeller 20 to rotate. Here, the driving member 30 can be arranged in the accommodation space 101 of the housing 10, or can be installed outside the housing 10, and the driving shaft of the driving member 30 extends into the accommodation space 101 to connect the impeller 20.
[0066] In some embodiments, the inlets of the first air outlet duct 102 and the second air outlet duct 103 are respectively arranged on the outer periphery of the housing 10, and the inlets of the two ducts are arranged in a staggered manner in the axial direction of the rotation axis of the impeller 20. As shown in Figure 9 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, which is convenient for the air flow at different positions in the housing 10 to flow out through different ducts and reduces the air flow 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 accommodating space 101, and the rotation of the wind wheel 20 makes the airflow in the accommodating 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 accommodating space 101, and the rotation of the wind wheel 20 makes the airflow in the accommodating 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 Figure 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 (eg Figure 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, the use of two volutes allows each volute to 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 about the rotation axis of the wind rotor 20. 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. As a result, the first volute 11 and the second volute 12 are 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. The first air outlet duct 102 and the second air outlet duct 103 can be arranged on opposite sides of the wind rotor 20 in the radial direction. This helps maintain the balance and stability of the fan assembly 100 structure, balances the airflow, reduces vibration and noise, and improves the efficiency of the wind rotor 20. This improves the air outlet effect of the wind rotor 20.
[0070] like Figure 11As shown, in some embodiments, in the rotational axis direction of the wind wheel 20, the thickness dimension of the portion of the wind wheel 20 located within the first volute 11 is H1, and the thickness dimension of the portion of the wind wheel 20 located within the second volute 12 is H2. H1 is the same as H2. That is to say, the height of the flow channel within the first volute 11 is the same as the height of the flow channel within the second volute 12, so that the air volume within the two volutes is the same, and the air output volume of the first air duct outlet 1021 and the second air duct outlet 1031 is the same, thus making the air supply in all directions more uniform.
[0071] As Figure 11 shown, in some embodiments, the housing 10 further includes a partition plate 13. The partition plate 13 is disposed within the accommodation space 101, between the first volute 11 and the second volute 12, and the partition plate 13 is connected at the connection of the first volute 11 and the second volute 12, which can reduce the mutual interference of the airflows generated by the rotation of the wind wheel 20 within the first volute 11 and the second volute 12. Furthermore, the stability of the air supply of the first air outlet duct 102 and the second air outlet duct 103 can be improved. At the same time, the structural strength of the housing 10 can be increased, and the service life of the fan assembly 100 can be extended.
[0072] The partition plate 13 extends along the circumferential direction of the wind wheel 20. The partition plate 13 can be perpendicular to the rotational axis direction of the wind wheel 20. The wind wheel 20 and the partition plate 13 are arranged at intervals, which can 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] As Figure 11 shown, in some examples, the distance between the wind wheel 20 and the partition plate 13 is d. Among them, due to the possible vibration during the rotation of the wind wheel 20, if this distance is too small, it is easy to interfere with the partition plate 13 when the wind wheel 20 rotates; if this distance is too large, there will be more communication in the flow between the two volutes, which will lead to the mutual interference of the airflows within the two volutes. Therefore, the distance d between the wind wheel 20 and the partition plate 13 is limited to be between 2 mm and 10 mm. d can be any value among 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm or any range value between any two of them. Thereby, it can not only ensure that the operation of the wind wheel 20 does not interfere, but also ensure the independence of the flow channels of the two volutes, and improve the stability of the air supply of the fan assembly 100.
[0074] As 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, reducing the assembly steps, thereby improving production efficiency and reducing costs. Moreover, this can reduce the seams or connection points, thereby providing a smoother air flow path, reducing eddies and turbulence, and thus improving the efficiency and performance of the wind wheel 20.
[0075] As Figures 9 - 11 shown, in some embodiments, the first air outlet duct 102 has a first duct outlet 1021, and the second air outlet duct 103 has a second duct outlet 1031. The centerlines of the first duct outlet 1021 and the second duct outlet 1031 are respectively parallel to the rotation axis of the wind wheel 20.
[0076] By setting the centerlines of the two air outlet ducts to be parallel to the rotation axis, it can be ensured that the air inhaled by the wind wheel 20 can be discharged from the two outlets in a balanced manner after being accelerated by the wind wheel 20, optimizing the air flow path, reducing energy loss, and thus 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. 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 then re-introduces it into the storage cavity 501 to realize the circulating flow path of the gas.
[0078] As Figure 16 shown, in some embodiments, the first duct outlet 1021 has a length direction (such as Figure 16 the second direction F2 shown). In the length direction, the first air outlet duct 102 has a first duct wall 141 and a second duct wall 142 arranged oppositely. The included angle between the first duct wall 141 and the second duct wall 142 is α1. Among them, if α1 is too large, the included angle between the two duct walls is too large, which will cause the air outlet to be too divergent, thus affecting the air outlet effect. Therefore, α1 is limited between 0 - 45°. α1 can be any point value or any range value between any two of 0, 10°, 15°, 20°, 30°, 40°, 45°. When α1 is 0, the first duct wall 141 and the second 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] As Figure 17 shown, in some embodiments, the second duct outlet 1031 has a length direction (such as Figure 17The second direction F2) shown. In the length direction, the second air outlet duct 103 has a relatively arranged third duct wall 151 and a fourth duct wall 152. The included angle between the third duct wall 151 and the fourth duct wall 152 is α2. Among them, if α2 is too large, the included angle between the two duct walls is too large, which will cause the air outlet to be too divergent, thus affecting the air outlet effect. Therefore, α2 is limited to between 0 - 45°. α2 can be any point value or any range value between any two of 0, 10°, 15°, 20°, 30°, 40°, 45°. When α2 is 0, the third duct wall 151 and the fourth 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] As Figures 13 - 17 shown, in some embodiments, the first air outlet duct 102 and the second air outlet duct 103 are relatively arranged to be suitable for sending air to the storage cavity 501. Among them, 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. Thus, there is both air supply from the top to the bottom and air supply from the bottom to the top in the storage cavity 501, thereby increasing the air volume in the storage cavity 501 and improving the uniformity of air supply at the same time.
[0081] As Figure 16 shown, in some embodiments, the first air outlet duct 102 has two relatively arranged first duct walls 141 and a second duct wall 142. The second duct wall 142 is farther from the top of the storage cavity 501 than the first duct wall 141. Among them, if the inclination angle of the second duct wall 142 relative to the horizontal direction is too small, within a certain air outlet distance, the position where the air outlet reaches is too high, which will cause the air sent out to be difficult to extend to the bottom of the storage cavity 501, thus affecting the air supply effect, resulting in uneven gas in the storage cavity 501, and further affecting the refrigeration or heating effect; while if the inclination angle of the second duct wall 142 relative to the horizontal direction is too large, part of the air volume will flow outside the storage cavity 501, causing waste of air volume and reducing the air supply effect of the fan assembly 100.
[0082] Therefore, the included angle α3 between the second duct wall 142 and the horizontal direction is limited to between 20° - 75°. α3 can be any point value or any range value between any two of 20°, 30°, 40°, 50°, 60°, 70°, 75°. Thus, it can not only increase the air supply range but also avoid waste of air volume and improve the air supply effect.
[0083] As Figure 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. Within a certain air outlet distance, the air outlet is delivered to a position too low, which will cause the delivered air 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 Figures 7 - 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 rotation axis 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 be sent 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. The bottom plate 16 is sealed with the second volute 12, and the driving 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 an embodiment of the present utility model includes a fan assembly 100 according to an embodiment of the utility model. By adopting the above-mentioned fan assembly 100, the storage cavity 501 of the storage device 200 can be supplied with air from different positions, which can not only improve the utilization rate of the air volume and the efficiency of the impeller 20, but also improve the uniformity of the air supply and the air supply effect, thereby improving the refrigeration and heating effects of the storage device 200.
[0088] As Figures 1 - 17 shown, the storage device 200 according to an embodiment of the present utility model 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, and the first side wall 51 and the second side wall 52 can be arranged opposite to each other. The storage box 50 defines a storage cavity 501. The first side wall 51 is provided with a first air inlet 5021, and 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 communicated with the storage cavity 501. That is, the internal space of the storage box 50 forms a storage cavity for storing items such as food. Air inlets are provided on both side walls of the storage box 50, and the air inlets can allow cold air to enter the storage cavity 501. A heat exchange plate 411 is provided outside the storage box 50.
[0089] The fan assembly 100 includes an impeller 20. The fan assembly 100 has a first air duct outlet 1021 and a second air duct outlet 1031. Among them, 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 communicated with the storage cavity 501 through the first air inlet 5021, and the second air duct outlet 1031 is communicated with the storage cavity 501 through the second air inlet 5022.
[0090] Thus, a part of the air blown by the impeller 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 another 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 chamber, which can not only improve the utilization rate of the air volume and the efficiency of the impeller 20, but also improve the uniformity of the air supply, and thus is beneficial to the preservation of food in the storage cavity 501.
[0091] According to the storage device 200 of the embodiment of the present utility model, by providing air inlets on two side walls of the storage box 50 and adopting a 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, enhance the uniformity of the air volume in the storage cavity 501, and further improve the refrigeration and heating effects of the storage device 200.
[0092] As Figure 1 and Figure 2 shown, in some embodiments, the storage device 200 further includes a heat exchange member 60. The heat exchange member 60 can be an evaporator or a condenser for refrigeration or heating. The heat exchange member 60 can also be a liquid cooling pipe or a liquid cooling plate, and the liquid cooling pipe or the liquid cooling plate is connected to a coolant pool, etc.
[0093] The fan assembly 100 has a wind wheel 20. In the axial direction of the rotation axis 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 member 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 member 60 is located between the second air duct outlet 1031 and the second air inlet 5022. That is, a certain distance is designed between the air duct outlet and the air inlet of the storage box 50. Thus, a flow channel is formed 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 member 60 is located at the flow channel, so that the wind sent out by the fan assembly 100 can pass through the heat exchange member 60. That is, this place is the heat exchange area, and the air entering the storage cavity 501 is the cold air after being heat-exchanged by the heat exchange member 60, so that the temperature in the storage cavity 501 can be effectively reduced and the refrigeration and heating effects can be improved.
[0094] Since at least a part of the heat exchange member 60 is located between the second air duct outlet 1031 and the second air inlet 5022, and at least a part 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 member 60, and the gas in the flow channel can fully contact and exchange heat with the heat exchange member 60, further improving the refrigeration and heating effects.
[0095] As Figure 1 shown, in some embodiments, the fan assembly 100 is arranged between the heat exchange plate 411 and the storage box 50, thereby improving the space utilization rate. The heat exchange member 60 is arranged outside the heat exchange plate 411, and the heat exchange member 60 does not occupy the space inside the heat exchange plate 411, improving the air supply space.
[0096] In some examples, the heat exchange member 60 is an evaporator. The flat tubes of the evaporator are arranged on the outer surface of the heat exchange plate 411. The flat tubes of the evaporator 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] As Figures 12 - 14 shown, in some embodiments, the first air inlet 5021 includes a plurality of air inlet holes, and the second air inlet 5022 includes a plurality of air inlet holes. Each air inlet hole is elongated, such as oval or rectangular. By providing a plurality of elongated air inlet holes, the air passing area can be increased, the air volume entering the storage cavity 501 can be increased, and by adopting the design of a plurality of small holes, the uniformity of air supply can be improved, and the air supply speed can be increased to a certain extent, so as to quickly reduce the temperature in the storage cavity 501, improve the cooling effect, and improve the performance of the storage device 200.
[0098] As Figure 6 、 Figures 12 - 14 shown, in some embodiments, on the side of the first side wall 51 facing away from the second side wall 52, there are two first sealing ribs 511. The first sealing ribs 511 extend towards the direction close to the corresponding heat exchange plate 411. 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, the sealing performance of the flow channel between the first side wall 51 and the heat exchange plate 411 is improved to a certain extent, so that the air flowing out from the first air duct outlet 1021 can stay 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 air volume utilization rate, but also make the air flowing out from the first air duct outlet 1021 stay in the first air inlet 5021 as soon as possible, improving the air supply efficiency.
[0099] As Figure 6 shown, in some examples, the first sealing ribs 511 are arranged at intervals with the heat exchange plate 411. The shortest distance between the first sealing ribs 511 and the heat exchange plate 411 is a, that is, the gap distance between the edge of the first sealing ribs 511 and the heat exchange plate 411 is a. Among them, if a is too small, the storage box 50 is likely to interfere during the assembly with the heat exchange plate 411. If a is too large, the gap at this place is too large and it is difficult to form a relatively closed space. Therefore, a can be limited to be between 1 mm and 6 mm. a can be any value among 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm or any range value between any two of them. Thereby, both the flow channel sealing and the assembly process can be taken into account.
[0100] As Figure 6As shown, in some embodiments, on the side of the second side wall 52 facing away from the first side wall 51, there are two second sealing ribs 521. The second sealing ribs 521 extend towards the corresponding heat exchange plate 411. 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, to a certain extent, the sealing of the flow channel between the second side wall 52 and the heat exchange plate 411 is improved, so that the air flowing out from the second air duct outlet 1031 can stay at the second air inlet 5022 of the second side wall 52 as much as possible. This can not only reduce the loss of air volume and improve the air volume utilization rate, but also enable the air flowing out from the second air duct outlet 1031 to stay in the second air inlet 5022 as soon as possible, improving the air supply efficiency.
[0101] As Figure 6 shown, in some examples, the second sealing ribs 521 are arranged at intervals from the inner wall surface of the heat exchange plate 411. The shortest distance between the second sealing ribs 521 and the heat exchange plate 411 is b, that is, the clearance distance between the edge of the second sealing rib 521 and the heat exchange plate 411 is b. Among them, if b is too small, interference is likely to occur when the storage box 50 is assembled with the heat exchange plate 411. If b is too large, it will lead to too large a gap at this place and it is difficult to form a relatively enclosed space. Therefore, b can be limited to between 1 mm and 6 mm. b can be any value among 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm or any range value between any two of them. Thereby, both the flow channel sealing and the assembly process can be taken into account.
[0102] As Figures 4 - 6 、 Figure 12 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 air 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. The air duct inlet 1041 is located on the side of the air wheel 20 close to the air outlet 503. Thereby, the air outlet 503 is communicated with the air duct inlet 1041. The air in the storage cavity 501 flows through the air outlet 503 to reach the air duct inlet 1041. The air flowing in from the air duct inlet 1041 flows through the air wheel 20 and is divided into two parts. One part flows through the first volute 11 and is sent out from the first air duct outlet 1021, and then reaches the first air inlet 5021 after flowing through the space flow channel between the two first sealing ribs 511 on the outer wall of the storage box 50 and the heat exchange plate 411. The other part enters the second volute 12 and is sent out from the second air duct outlet 1031, and then reaches the second air inlet 5022 after flowing through the space flow channel between the two second sealing ribs 521 on the outer wall of the storage box 50 and the heat exchange plate 411, and then reaches the air outlet 503 after flowing in the storage cavity 501, forming a complete cycle.
[0103] As 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 impeller 20. This can enable the air flow to directly and smoothly enter the air duct from the air outlet 503, reduce the loss and resistance of the air flow, improve the overall air flow efficiency; and can reduce the turbulence and eddy current of the air flow, thereby reducing noise; and the overall structural layout is more compact.
[0104] As Figures 7 - 11 shown, in some embodiments, the fan assembly 100 includes a first volute 11 and a second volute 12. The first volute 11 and the second volute 12 are arranged along the rotation axis direction of the impeller 20. The first volute 11 defines a part of the accommodation space 101, and the second volute 12 defines another part of the accommodation space 101. The impeller 20 is arranged in the accommodation space 101. Among them, 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. 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] Thus, the fan assembly 100 forms a double-layer volute structure, which can not only reduce the chaos and loss of the air flow, improve the stability and efficiency of the air flow, and reduce the air supply noise; but also guide the air flow to the corresponding air duct outlet, reduce the air flow chaos 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 member 60 is provided on the heat exchange plate 411. In the air supply direction, the heat exchange member 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 introduced into the storage cavity 501. The double-layer volute design not only ensures the cooling and heating effect, but also makes the air in the storage cavity 501 evenly distributed. 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 part 54 is provided at the bottom of the storage box 50, and the storage device further has a bottom plate 412. The bottom plate 412 is provided with a guiding part 43. The sliding part 54 is slidably matched with the guiding part 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 access.
[0108] In some embodiments, the storage device further includes a cover body 42. The top of the storage cavity 501 is open, and the cover body 42 is arranged on the top of the storage cavity 501. Among them, 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. Thus, the storage cavity 501 can be opened in a flip-up manner, which is flexible to use and meets the use requirements of special spaces.
[0109] AsFigure 2 and Figure 6 As shown in Figure 6 , in some embodiments, the storage device 200 has a bottom plate 412, a guiding portion 43 is provided on the bottom plate 412, the storage box 50 is installed on the bottom plate 412 through a sliding portion 54, a cover body 42 is arranged on the heat exchange plate 411, and the cover body 42 is connected to the heat exchange plate 411. Here, the connection can be a fixed connection, a detachable connection, or a rotational mating connection. Thus, the storage device can open the storage cavity by flipping the cover or by pulling it out. Therefore, when applied to special scenarios, such as in a vehicle, it is convenient for the driver and front passenger to flip the cover, and it is also convenient for the rear passengers to pull it out.
