[0064] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0065] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0066] It should be noted that in order to solve the technical problems of low refrigeration power, slow refrigeration speed and large space occupied caused by the use of an independent micro-compressor for refrigeration in the car refrigerator 1000, it is possible to consider integrating the car refrigerator 1000 into the vehicle's thermal management system 2000, and use the vehicle's thermal management system 2000 to dissipate the heat in the body 100 of the car refrigerator 1000. This can not only increase the effective volume of the car refrigerator 1000, but also avoid the problem of heat dissipation toward the interior of the car due to the use of an independent micro-compressor.

[0067] However, if the heat exchanger of the vehicle's air conditioner and the heat exchanger of the car refrigerator 1000 are simply connected in parallel (that is, the outlets of the air conditioner heat exchanger and the car refrigerator 1000 are combined and then enter the gas-liquid separator together, and then enter the air intake of the compressor), then the evaporation pressures of the air conditioner heat exchanger and the car refrigerator 1000 will be the same. Under normal circumstances, in the dual-opening mode of passenger compartment refrigeration and car refrigerator 1000 cooling, the target evaporation temperature of the passenger compartment is generally 0°C, and the corresponding evaporation pressure is about 300 kPa. The target evaporation temperature of the car refrigerator 1000 is generally -10°C, and the corresponding evaporation pressure is about 200 kPa. The evaporation temperature and evaporation pressure are coupled. The lower the evaporation temperature, the lower the evaporation pressure.

[0068] That is to say, the evaporation pressures corresponding to the cooling of the passenger compartment of the vehicle and the cooling of the vehicle refrigerator 1000 are different. However, if only the heat exchanger of the vehicle air conditioner and the heat exchanger of the vehicle refrigerator 1000 are connected in parallel, the evaporation pressures of the heat exchanger of the air conditioner and the heat exchanger of the vehicle refrigerator 1000 will be the same. In this way, when the air conditioner is used as the benchmark, the heat exchanger of the vehicle refrigerator 1000 will exchange heat with the heat in the box 100 at a very slow speed, which will cause the temperature in the box 100 to be relatively high for a long time, and it is impossible to reach the temperature that meets the user's needs, thereby reducing the user's experience. When the vehicle refrigerator 1000 is used as the benchmark At this time, because the evaporation pressure of the heat exchanger of the vehicle refrigerator 1000 is set to about 200 kPa, and the evaporation pressure of the heat exchanger of the air conditioner is set to about 300 kPa, it is necessary to reduce the pressure of the heat exchanger outlet on the air-conditioning side of the passenger compartment to about 200 kPa through throttling and other solutions, that is, to be consistent with the evaporation pressure of the heat exchanger of the vehicle refrigerator 1000, and then merge the outlets of the heat exchanger of the air conditioner with the outlet of the heat exchanger of the vehicle refrigerator 1000 and enter the air intake port of the compressor, which will cause the invalid pressure loss of the refrigeration circuit on the air-conditioning side of the passenger compartment to increase, the flow rate of the refrigerant to decrease, and the cooling capacity to decrease, affecting the cooling effect of the passenger compartment.

[0069] To solve the above problems, the present application proposes a vehicle refrigerator 1000 for a vehicle, which specifically integrates the vehicle refrigerator 1000 into the thermal management system 2000 of the vehicle, and sets a spoiler component 300 in the box 100 of the vehicle refrigerator 1000. The spoiler component 300 is used to drive the air flow in the accommodating cavity 110 of the box 100. Compared with the natural convection heat exchange of the air in the original box 100, the spoiler component 300 can realize the forced convection heat exchange of the air in the box 100. In this way, the evaporation temperature of the vehicle refrigerator 1000 does not need to be lowered to a too low temperature (for example, below -10°C). When it is close to the evaporation temperature of the air conditioner (for example, about 0 to 5°C), it can also meet the functional requirement of refrigeration at a temperature below -10°C in the vehicle refrigerator, thereby making the storage temperature and cooling speed of the vehicle refrigerator 1000 meet the needs of passengers. At the same time, the refrigeration flow path of the passenger compartment air conditioner can also cool the passenger compartment according to its own evaporation temperature requirements. There is no need to artificially reduce the pressure and then merge with the refrigeration circuit of the vehicle refrigerator 1000 before entering the compressor. This reduces the technical problems of reduced refrigeration capacity and refrigeration efficiency due to pressure loss. As a result, the vehicle refrigerator 1000 of the present application not only occupies a small space, but also can simultaneously meet the refrigeration needs of the passenger compartment and the refrigeration needs of the vehicle refrigerator 1000, thereby improving the user experience.

[0070] That is to say, the present application integrates the heat pump system of the vehicle refrigerator 1000 and the heat pump system of the vehicle air conditioner. That is, when the vehicle refrigerator 1000 and the vehicle's air conditioner are turned on in cooling mode at the same time, the compressor and the heat dissipation system are shared, and the spoiler component 300 is used at the same time to improve the cooling efficiency, so that both the vehicle refrigerator 1000 and the air conditioner can achieve better cooling effects in a shorter time, thereby realizing an efficient dual-opening mode of air conditioning refrigeration and vehicle refrigerator 1000 cooling.

[0071] The following describes a vehicle refrigerator 1000 for a vehicle according to an embodiment of the present invention with reference to the accompanying drawings.

[0072] Among them, the vehicle has a thermal management system 2000, such as Figure 1 As shown, the thermal management system 2000 includes a first heat exchange branch 2100 and a second heat exchange branch 2200 , and the first heat exchange branch 2100 is used to adjust the cabin temperature.

[0073] It should be noted that the adjustment of the cabin temperature mentioned here can be to increase the cabin temperature or to lower the cabin temperature, so that the cabin temperature can be maintained within a suitable temperature range to improve the comfort of the vehicle and thus improve the user experience.

[0074] Combination Figure 1 , Figure 2 and Figure 3 As shown, a vehicle refrigerator 1000 for a vehicle according to an embodiment of the utility model includes: a box body 100 , a heat exchange component 200 and a spoiler component 300 .

[0075] Among them, combined Figure 1 , Figure 2 and Figure 3 As shown, a receiving cavity 110 is formed in the box body 100. The receiving cavity 110 is mainly used to provide a receiving space so that items can be placed in the box body 100, that is, the items can be placed in the vehicle refrigerator 1000, so that the vehicle refrigerator 1000 can be used to refrigerate food and drinks to maintain the freshness and taste of food and drinks, which can greatly improve the travel experience of the vehicle.

[0076] In some embodiments, the interior of the box body 100 is hollow to form the accommodating cavity 110 , which reduces the difficulty of molding the accommodating cavity 110 .

[0077] Combination Figure 1 , Figure 2 and Figure 3 As shown, the heat exchange component 200 is disposed in the box body 100 , and the heat exchange component 200 is used to adjust the air temperature in the accommodating cavity 110 . The heat exchange component 200 is connected to the second heat exchange branch 2200 .

[0078] Among them, by setting up a heat exchange component 200 and using the heat exchange component 200 to adjust the air temperature in the accommodating chamber 110, it can be ensured that the temperature in the accommodating chamber 110 can be maintained within an appropriate temperature range, thereby ensuring the refrigeration effect of the vehicle refrigerator 1000 and improving the user experience; by connecting the heat exchange component 200 to the second heat exchange branch 2200, the heat exchange component 200 can be integrated into the thermal management system 2000 of the vehicle, so that while ensuring the heat exchange performance of the heat exchange component 200, the heat pump system of the vehicle refrigerator 1000 and the heat pump system of the vehicle's air conditioner can be integrated, so that the compressor and heat pump system separately set up and applied to the vehicle refrigerator 1000 can be eliminated, which is convenient for reducing the occupied space of the vehicle refrigerator 1000 and is beneficial to increasing the refrigeration space of the vehicle refrigerator 1000.

[0079] Combination Figure 1 , Figure 2 and Figure 3 As shown, the spoiler assembly 300 is disposed in the accommodating cavity 110 , and the spoiler assembly 300 is used to drive the air flow in the accommodating cavity 110 .

[0080] It should be noted that when the heat exchange component 200 is used to adjust the air temperature in the accommodating cavity, on the one hand, since the accommodating cavity 110 has a certain space, it is easy for the temperature distribution in each area of ​​the accommodating cavity 110 to be uneven, which leads to less effective refrigeration space of the vehicle refrigerator 1000. On the other hand, the evaporation pressures corresponding to the cooling of the vehicle's passenger compartment and the cooling of the vehicle refrigerator 1000 are different, which affects the refrigeration efficiency of the vehicle refrigerator 1000.

[0081] Based on this, the present application sets a spoiler component 300 in the accommodating cavity 110, and the spoiler component 300 drives the air flow in the accommodating cavity 110. The spoiler component 300 can be used to mix the air in various areas of the accommodating cavity 110, which is beneficial to improving the uniformity of the air temperature in the accommodating cavity 110, thereby improving the refrigeration efficiency of the vehicle refrigerator 1000.

[0082] In summary, the vehicle refrigerator 1000 of the present application, while arranging the heat exchange component 200 in the box 100 of the vehicle refrigerator 1000, also arranges the spoiler component 300 inside the box 100, so that a uniform flow field can be formed in the box 100, which greatly improves the refrigeration efficiency, so as to ensure the working performance of the vehicle refrigerator 1000.

[0083] It can be seen from the above structure that the vehicle refrigerator 1000 used in the vehicle of the embodiment of the utility model, by setting a heat exchange component 200 and connecting the heat exchange component 200 to the second heat exchange branch 2200, not only realizes the use of the vehicle's thermal management system 2000 to ensure the refrigeration effect of the vehicle refrigerator 1000, but also can save the compressor and heat pump system separately set up and applied to the vehicle refrigerator 1000, thereby reducing the occupied space of the vehicle refrigerator 1000 and helping to increase the refrigeration space of the vehicle refrigerator 1000.

[0084] At the same time, by setting a spoiler component 300 in the accommodating cavity 110, the spoiler component 300 can be used to drive the air flow in the accommodating cavity 110, thereby facilitating the mixing of air in various areas in the accommodating cavity 110, which is beneficial to improving the uniformity of air temperature in the accommodating cavity 110, and further improving the refrigeration efficiency of the vehicle refrigerator 1000.

[0085] That is to say, the vehicle refrigerator 1000 of the present application not only saves space but also can achieve efficient refrigeration to ensure the working performance of the vehicle refrigerator 1000 and reduce the difficulty of installing the vehicle refrigerator 1000.

[0086] It can be understood that compared with the prior art, the vehicle refrigerator 1000 of the present application can not only utilize the vehicle's thermal management system 2000 to adjust its own refrigeration effect, but also ensure the refrigeration efficiency, so that the vehicle refrigerator 1000 of the present application not only saves space but also can achieve efficient refrigeration, so as to ensure the working performance of the vehicle refrigerator 1000 and enhance the user experience.

[0087] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4 As shown, the box body 100 has a top cover 120, which is detachably arranged on the top of the box body 100 so that the accommodating cavity 110 has an opening, thereby facilitating the installation of the spoiler assembly 300, and conveniently taking out items from the accommodating cavity 110 and placing items in the accommodating cavity 110, thereby improving the ease of use of the vehicle refrigerator 1000.

[0088] In some embodiments, the heat exchange assembly 200 is a heat exchange tube, which is arranged around the outer periphery of the box 100. In this way, the heat exchange tube can be used to exchange heat with the box 100 to change the temperature of the box 100, thereby achieving the purpose of adjusting the air temperature in the accommodating chamber 110.

[0089] At the same time, by surrounding the heat exchange tubes on the outer periphery of the box body 100, the difficulty of arranging the heat exchange tubes and the difficulty of connecting the heat exchange tubes with the thermal management system 2000 can be reduced, making it easier to use the thermal management system 2000 to reduce the temperature inside the box body 100.

[0090] In some embodiments, in combination Figure 2 , Figure 3 and Figure 4 As shown, the heat exchange tube has a first interface 210 and a second interface 220, one of the first interface 210 and the second interface 220 is formed as a liquid inlet of the heat exchange tube, and the other is formed as a liquid outlet of the heat exchange tube, and the first interface 210 and the second interface 220 are respectively connected to the second heat exchange branch 2200 of the thermal management system 2000, so as to facilitate the use of the vehicle's thermal management system 2000 to adjust the temperature inside the box 100.

[0091] In some embodiments, the heat exchange tubes extend along the circumference of the housing 100 and are arranged along the axial direction of the housing 100 so that the heat exchange tubes can completely cover the outer surface of the housing 100 , thereby ensuring the heat exchange effect between the heat exchange tubes and the housing 100 .

[0092] It should be noted that the heat exchange tube can be connected to the outer periphery of the box body 100 by bonding, clamping or other connection methods. While reducing the fixed connection of the heat exchange tube, the position of the heat exchange tube relative to the box body 100 can also be stabilized, thereby facilitating the use of the heat exchange tube to adjust the air temperature in the accommodating cavity 110.

[0093] It should also be noted that by surrounding the heat exchange tubes on the outer periphery of the box body 100 and providing a spoiler assembly 300 in the accommodating cavity 110, it is also possible to avoid, to a certain extent, a large temperature difference between the center of the accommodating cavity 110 and the surrounding walls, thereby making the temperature distribution in the accommodating cavity 110 uniform, which is beneficial to improving the working performance of the vehicle refrigerator 1000.

[0094] Of course, in some other embodiments, the heat exchange component 200 can also be formed as a heat exchange plate, and the heat exchange plate or heat exchange tube is arranged in the box body 100, so that the purpose of using the heat exchange component 200 to adjust the air temperature in the accommodating cavity 110 can also be achieved.

[0095] In some embodiments, the housing 100 is made of metal material, which not only ensures the structural strength of the housing 100, but also facilitates the heat exchange between the heat exchange component 200 and the inside of the housing 100, thereby ensuring the heat exchange effect.

[0096] In some embodiments, in combination Figure 4 , Figure 5 and Figure 6As shown, the spoiler assembly 300 includes a duct member 310 and a spoiler 320. The duct member 310 is arranged in the accommodating cavity 110. The duct member 310 itself or the duct member 310 cooperates with the box body 100 to define an accommodating space 330 for accommodating the spoiler 320. The duct member 310 is provided with an air inlet 311 and an air outlet 312 connected to the accommodating space 330. The spoiler 320 is arranged in the accommodating space 330. The spoiler 320 is used to drive the air in the accommodating cavity 110 to enter the accommodating space 330 from the air inlet 311 and be discharged through the air outlet 312. What is meant here is that when the air duct member 310 is arranged in the accommodating cavity 110, a accommodating space 330 and an air inlet 311 and an air outlet 312 connecting the accommodating space 330 can be formed in the accommodating cavity 110. The accommodating space 330 is used to accommodate the spoiler 320, so that the spoiler 320 is arranged in the accommodating cavity 110, and the spoiler 320 is used to drive the air in the accommodating cavity 110 to enter the accommodating space 330 from the air inlet 311 and drive the air entering the accommodating space 330 to be discharged through the air outlet 312, so that the air in the accommodating cavity 110 can circulate, so that the air in each area of ​​the accommodating cavity 110 can be mixed, which is beneficial to improving the uniformity of the air temperature in the accommodating cavity 110, and further improving the refrigeration efficiency of the vehicle refrigerator 1000.

[0097] In some embodiments, in combination Figure 4 , Figure 5 and Figure 6 As shown, at least part of the duct member 310 is spaced apart from the box body 100 , so that the duct member 310 and the box body 100 cooperate to define a receiving space 330 for receiving the spoiler 320 , thereby reducing the difficulty of forming the receiving space 330 .

[0098] Of course, in some other embodiments, the air duct member 310 may also be configured to be hollow inside, so that the air duct member 310 itself is used to define the accommodation space 330 .

[0099] In some embodiments, in combination Figure 7-10 As shown, the spoiler assembly 300 further includes a driving member 350, which is used to drive the spoiler 320 to rotate, thereby ensuring the working performance of the spoiler 320, so that the air in the accommodating cavity 110 can circulate.

[0100] The driving member 350 mentioned here may be a rotating motor. Figure 6 The dashed arrow shown in the spoiler 320 indicates the rotation direction of the spoiler 320 .

[0101] In some embodiments, in combination Figure 5 and Figure 6As shown, the air duct member 310 is arranged close to the top wall of the accommodating cavity 110, and the air outlet 312 is located below the air inlet 311. By arranging the air duct member 310 close to the top wall of the accommodating cavity 110, the spoiler assembly 300 can be arranged close to the top wall of the accommodating cavity 110, which ensures that the spoiler assembly 300 can effectively drive the air flow in the accommodating cavity 110, and at the same time, it can also avoid the spoiler assembly 300 from occupying more space in the box 100, thereby improving the space utilization rate of the box 100, so that the box 100 can provide a larger cooling space and improve the user experience.

[0102] At the same time, by setting the air outlet 312 to be located below the air inlet 311, the spoiler assembly 300 can achieve an upper air intake and lower air outlet mode, which is beneficial to maximize the control of the air circulation flow in the accommodating cavity 110 and ensure the working performance of the spoiler assembly 300.

[0103] in, Figure 5 The dashed line with arrows in the middle shows the circulation flow path of the air in the accommodating chamber 110 .

[0104] In some embodiments, Figure 5 As shown, the duct member 310 is arranged close to the top wall of the accommodating cavity 110 and is located on one side in the width direction of the accommodating cavity 110, so that the spoiler assembly 300 can be arranged at the corner of the accommodating cavity 110. While ensuring the working performance of the spoiler assembly 300, the space utilization rate in the box body 100 can also be improved.

[0105] It should be noted that, since the box body 100 has a top cover 120 , the air duct member 310 being disposed close to the top wall of the accommodating chamber 110 mentioned here can also be understood as the air duct member 310 being disposed close to the top cover 120 .

[0106] In some embodiments, in combination Figure 5 and Figure 6 As shown, at least a portion of the duct member 310 is used to define the air outlet 312 to extend downwardly in an inclined direction. In other words, at least a portion of the duct member 310 defines the air outlet 312 to extend downwardly in an inclined direction, so that the air outlet 312 can be inclined to discharge air downwardly, which is conducive to maximizing the control of the air circulation flow in the accommodating cavity 110 and ensuring the working performance of the spoiler assembly 300.

[0107] At the same time, by directly using the air duct member 310 to define the air outlet 312 extending obliquely downward, the difficulty of forming the air outlet 312 can also be reduced.

[0108] In some embodiments, in combination Figure 6-Figure 10As shown, the air duct member 310 includes a first air guide member 313 and a second air guide member 314 that are spaced apart, a spoiler 320 is arranged between the first air guide member 313 and the second air guide member 314, the second air guide member 314 is provided with an air inlet 311, and an air outlet 312 is formed between the first air guide member 313 and the second air guide member 314. It can be understood here that the first air guide member 313 and the second air guide member 314 cooperate to form the air duct member 310, and the first air guide member 313 and the second air guide member 314 cooperate to directly form a receiving space 330 for receiving the spoiler 320 and an air inlet 311 and an air outlet 312 that are connected to the receiving space 330, thereby reducing the molding difficulty of the receiving space 330, the air inlet 311 and the air outlet 312, that is, reducing the molding difficulty of the spoiler assembly 300.

[0109] It should be noted that the second air guide 314 mentioned above having the air inlet 311 may be the second air guide 314 itself defining the air inlet 311 , or the second air guide 314 and the box body 100 cooperate to define the air inlet 311 .

[0110] In some embodiments, Figure 6 As shown, the second air guide member 314 is spaced apart from the top wall of the box body 100 to form an air inlet and outlet 311 between the second air guide member 314 and the top wall of the box body 100. Compared with using the second air guide member 314 itself to define the air inlet and outlet 311, the opening on the second air guide member 314 can be omitted to reduce the difficulty of forming the air inlet 311.

[0111] Of course, in some other embodiments, an opening may be formed on the second air guide member 314 to form the air inlet 311 .

[0112] In addition, by utilizing the first air guide member 313 and the second air guide member 314 to cooperate to form the air outlet 312, while reducing the difficulty of forming the air outlet 312, it is beneficial to reduce the area of ​​the air outlet 312 and increase the wind speed of the air outlet 312. This can promote the air flow exchange inside the body 100 of the vehicle refrigerator 1000, thereby improving the refrigeration efficiency of the vehicle refrigerator 1000.

[0113] In some embodiments, Figure 6 As shown, the first air guide member 313 and the second air guide member 314 located on opposite sides of the air outlet 312 extend obliquely toward the bottom wall of the accommodating cavity 110. In this way, the air outlet 312 extending obliquely downward can be defined by at least part of the air duct member 310, which reduces the difficulty of forming the air outlet 312 and enables the air outlet 312 to discharge air obliquely downward, which is conducive to maximizing the control of the air circulation flow in the accommodating cavity 110 and ensuring the working performance of the spoiler assembly 300.

[0114] In some embodiments, in combination Figure 6 , Fig. 9 and Fig.10 As shown, the first air guide member 313 is connected to the side wall of the accommodating cavity 110, and the first air guide member 313 has a first air guide portion 3131 and a second air guide portion 3132. The first air guide portion 3131 has a first air guide wall 31311 facing the spoiler 320, and the first air guide wall 31311 extends along the outer surface of the spoiler 320. The second air guide portion 3132 is connected to one end of the first air guide portion 3131 close to the air outlet 312, and the second air guide portion 3132 has a second air guide wall 31321 facing the spoiler 320, and the second air guide wall 31321 is tangent to the first air guide wall 31311. That is to say, the extension direction of the first guide wall 31311 is consistent with the extension direction of the outer surface of the spoiler 320, so that it is convenient to form a guide channel with a certain space between the first guide portion 3131 and the spoiler 320, which is beneficial to supply air toward the air outlet 312. At the same time, because the second guide portion 3132 is connected to the end of the first guide portion 3131 close to the air outlet 312, by setting the second guide wall 31321 to be tangent to the first guide wall 31311, it is convenient to increase the gap between the second guide wall 31321 and the spoiler 320, which is beneficial to increase the area of ​​the air outlet channel close to the air outlet 312, thereby ensuring the air outlet volume and improving the working performance of the spoiler assembly 300.

[0115] In addition, by connecting the first air guide member 313 to the side wall of the accommodating cavity 110, while the spoiler assembly 300 is disposed at the corner of the accommodating cavity 110, the box body 100 can also be used to support the first air guide member 313, that is, to support the spoiler assembly 300, thereby improving the position stability of the spoiler assembly 300 and ensuring the working performance of the spoiler assembly 300.

[0116] In some embodiments, the first air guide 313 is fixedly connected to the side wall of the accommodating cavity 110 .

[0117] The fixed connection mentioned here may be bonding, welding or bolt connection, etc.

[0118] Of course, in some other embodiments, the first air guide 313 may also be closely attached to the side wall of the accommodating cavity 110 .

[0119] In some embodiments, the angle between the second guide wall 31321 and the side wall is in the range of 5° to 70°. The side wall here refers to the side wall connecting the first air guide 313 to the accommodating cavity 110. The angle between the second guide wall 31321 and the side wall can be understood as Figure 6As shown in the figure, the first air guide 313 and the second air guide 314 cooperate to form the air outlet 312. When α1 is small, the area of ​​the air outlet 312 will be adaptively increased, which is not conducive to ensuring the air outlet speed; when α1 is large, the area of ​​the air outlet 312 will be adaptively reduced, which is not conducive to ensuring the air outlet volume and controlling the air outlet 312 to tilt downward to discharge air.

[0120] Therefore, the present application sets the angle between the second guide wall 31321 and the side wall to a range of 5° to 70°, so that while ensuring the air outlet speed, the air outlet volume can also be guaranteed, and it is beneficial to control the air outlet 312 to tilt downward to discharge air, thereby ensuring the air outlet effect of the air outlet 312.

[0121] In a specific example, the angle between the second guide wall 31321 and the side wall is 5°, 10°, 20°, 30°, 40°, 50°, 60° or 70°, etc.

[0122] In some embodiments, the angle between the second guide wall 31321 and the second air guide member 314 is in the range of 0° to 45°. Figure 6 α2 shown in the figure, through the above arrangement, while ensuring the opening size of the air outlet 312, it can also ensure that the air outlet 312 can extend downwardly in an inclined direction, so that the air outlet 312 can outlet air in an inclined direction downward, thereby ensuring the air outlet effect of the air outlet 312.

[0123] In some embodiments, the angle between the second guide wall 31321 and the second air guide member 314 is 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40° or 45°, etc.

[0124] In some embodiments, the minimum distance between the first guide wall 31311 and the spoiler 320 is in the range of 3 mm to 8 mm. Here, it means that there are multiple distances between the first guide wall 31311 and the spoiler 320, and the minimum distance is in the range of 3 mm to 8 mm. The angle between the first guide wall 31311 and the spoiler 320 mentioned here can be understood as Figure 6 As shown in the figure, when H is small, on the one hand, it will affect the dynamic balance of the spoiler 320 during operation, and on the other hand, it will increase the noise of the spoiler 320 during operation; when H is large, it will affect the air volume and air speed of the air outlet 312, thereby affecting the air outlet effect of the air outlet 312.

[0125] Therefore, the present application sets the value range of the minimum distance between the first guide wall 31311 and the spoiler 320 to 3mm to 8mm. In this way, while improving the dynamic balance of the spoiler 320 during operation and reducing the noise of the spoiler 320 during operation, it can also ensure the air outlet volume and air outlet speed of the air outlet 312, thereby ensuring the air outlet effect of the air outlet 312.

[0126] In a specific example, the minimum distance between the first guide wall 31311 and the spoiler 320 is 3 mm, 4 mm, 5 mm, 6 mm, 7 mm or 8 mm, etc.

[0127] In some embodiments, in combination Figure 5 and Figure 6 As shown, the spoiler 320 is a spoiler fan, which is spaced apart from the top wall, and a minimum distance d1 between the spoiler fan and the top wall satisfies: d1 = 0.4d0 ~ 1.2d0, wherein d0 is the diameter of the spoiler fan. That is to say, when the spoiler 320 is arranged in the accommodating cavity 110, the spoiler 320 is spaced apart from the top wall of the accommodating cavity 110. Since the box body 100 has a top cover 120, it can also be understood here that the spoiler 320 and the top cover 120 are spaced apart, and the minimum distance d1 between the spoiler 320 and the top cover 120 is set to satisfy: d1=0.4d0~1.2d0. When d1 is small, there is not only a risk of mutual interference between the spoiler 320 and the top cover 120, but also the dynamic balance of the spoiler 320 during operation is affected, and the noise of the spoiler 320 during operation is increased; when d1 is large, on the one hand, it will affect the air volume and air speed of the air outlet 312, thereby affecting the air outlet effect of the air outlet 312, and on the other hand, it will cause part of the air above the accommodating cavity 110 to be unable to participate in the circulation flow, thereby affecting the refrigeration effect of the vehicle refrigerator 1000.

[0128] Therefore, the present application sets the minimum distance d1 between the spoiler fan and the top wall to satisfy: d1 = 0.4d0 ~ 1.2d0. While avoiding interference between the spoiler 320 and the top cover 120, it can also ensure the dynamic balance of the spoiler 320 during operation and reduce the noise of the spoiler 320 during operation. At the same time, it ensures the air outlet effect of the air outlet 312 and the heat exchange effect of the air in the accommodating cavity 110, thereby improving the refrigeration effect of the vehicle refrigerator 1000.

[0129] In a specific example, the minimum distance d1 between the turbulent fan and the top wall satisfies: d1 = 0.4d0, 0.5d0, 0.6d0, 0.7d0, 0.8d0, 0.9d0, 1.0d0, 1.1d0 or 1.2d0, etc.

[0130] In some embodiments, in combination Figure 5 and Figure 6As shown, the spoiler 320 is a spoiler fan, and the diameter d0 of the spoiler fan and the minimum width dimension W of the box 100 satisfy: d0 = 0.1W ~ 0.3W. Here, it means that the box 100 can have multiple widths, and the diameter of the spoiler 320 and the minimum width dimension W of the box 100 meet certain conditions, wherein the minimum width dimension W of the box 100 can be referred to Figure 5 When d0 is small, the spoiler 320 cannot drive the air circulation in the entire accommodating cavity 110, thereby reducing the refrigeration effect of the vehicle refrigerator 1000; when d0 is large, while increasing the manufacturing cost of the spoiler 320, it will also cause the spoiler 320 to occupy a larger space, thereby reducing the storage space of the accommodating cavity 110 and reducing the performance of the vehicle refrigerator 1000.

[0131] Therefore, the present application sets the diameter d0 of the spoiler fan and the minimum width dimension W of the box body 100 to satisfy: d0 = 0.1W ~ 0.3W. While ensuring the working performance of the spoiler 320, it is also beneficial to improve the space utilization of the accommodating cavity 110, thereby increasing the storage space of the accommodating cavity 110 and improving the user experience.

[0132] In a specific example, the diameter d0 of the turbulent fan and the minimum width dimension W of the box body 100 satisfy: d0 = 0.1W, 0.2W or 0.3W, etc.

[0133] In some embodiments, in combination Figure 3 , Figure 4 and Figure 5 As shown, the spoiler 320 is a cross-flow fan. The cross-flow fan has the advantages of large air supply volume and large air supply area, so under the condition of the same air supply volume, the cross-flow fan generates less noise.

[0134] Therefore, by setting the spoiler 320 as a cross-flow fan, the vehicle refrigerator 1000 of the present application can have the advantages of low noise, low energy consumption, etc.

[0135] At the same time, the cross-flow fan can better control the inlet and outlet directions of the air, thereby simplifying the structure of the duct member 310, reducing the molding difficulty and manufacturing cost of the duct member 310, so that the vehicle refrigerator 1000 has the advantages of simple structure, low manufacturing difficulty, and low manufacturing cost. In addition, the provision of a cross-flow fan can also avoid opening air inlet holes or air outlet holes on the box body 100, so that the box body 100 is complete to ensure the cooling effect of the vehicle refrigerator 1000, that is, to ensure the working performance of the vehicle refrigerator 1000, thereby improving the user experience.

[0136] In some embodiments, in combination Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the spoiler assembly 300 also includes two support members 340, which are axially spaced apart from the spoiler 320 and fixedly connected to the side wall of the accommodating chamber 110, the first air guide member 313, the second air guide member 314 and the axial ends of the spoiler 320 are respectively connected to the support members 340, and the spoiler 320 is rotatably connected to the support members 340, and the driving member 350 is provided on one of the support members 340, and the driving member 350 is used to drive the spoiler 320 to rotate relative to the support member 340, thereby ensuring the working performance of the spoiler 320.

[0137] The fixed connection mentioned here may be welding, bonding or clamping, etc.

[0138] The thermal management system 2000 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0139] like Figure 1 As shown, a thermal management system 2000 according to an embodiment of the present utility model includes: a first heat exchange branch 2100 and a second heat exchange branch 2200 .

[0140] Among them, the first heat exchange branch 2100 is used to adjust the cabin temperature, and the second heat exchange branch 2200 is used to adjust the temperature inside the box 100 of the vehicle refrigerator 1000. The vehicle refrigerator 1000 is the aforementioned vehicle refrigerator 1000, and the specific structure of the vehicle refrigerator 1000 will not be repeated here.

[0141] It can be seen from the above structure that the thermal management system 2000 of the embodiment of the utility model can not only adjust the cabin temperature, but also adjust the temperature inside the box 100 of the vehicle refrigerator 1000, so that the temperature inside the box 100 can be maintained within a suitable temperature range, thereby ensuring the refrigeration effect of the vehicle refrigerator 1000 and improving the user experience.

[0142] In some embodiments, Figure 1 As shown, the first heat exchange branch 2100 has a parallel heating branch 2110 and a cooling branch 2120, the heating branch 2110 and the cooling branch 2120 are respectively connected in series between the external heat exchanger 2150 and the gas-liquid separator 2170, the cooling branch 2120 is provided with an in-vehicle evaporator 2160, the liquid inlet of the external heat exchanger 2150 is connected to the outlet of the compressor 2130 through the in-vehicle condenser 2140, and the inlet of the compressor 2130 is connected to the outlet of the gas-liquid separator 2170.

[0143] At the same time, the outlet of the compressor 2130 is provided with a first temperature and pressure sensor 2181 for detecting the temperature and pressure of the refrigerant discharged from the compressor 2130, and the outlet of the in-vehicle condenser 2140 is provided with a first solenoid valve 2183 and a first expansion valve 2185 in parallel; the heating branch 2110 is provided with a second solenoid valve 2184 for controlling its on and off; the refrigeration branch 2120 is provided with a second expansion valve 2186 for throttling and reducing pressure and controlling its on and off, and a second temperature and pressure sensor 2182 for detecting the temperature and pressure of the refrigerant discharged from the in-vehicle evaporator 2160; the second heat exchange branch 2200 is connected in series in sequence with a third expansion valve 2210, a heat exchange component 200 and a third temperature and pressure sensor 2220.

[0144] In the description of the present utility model, features defined as “first”, “second”, and “third” may explicitly or implicitly include one or more such features, and are used to distinguish and describe the features, without any distinction of order or importance.

[0145] In some embodiments, Figure 1 As shown, the in-vehicle condenser 2140 , the out-vehicle heat exchanger 2150 and the in-vehicle evaporator 2160 are all provided with heat exchange fans 2187 facing them, and the heat exchange fans 2187 are used to improve the heat exchange efficiency of the in-vehicle condenser 2140 , the out-vehicle heat exchanger 2150 and the in-vehicle evaporator 2160 .

[0146] Through the above settings, the thermal management system 2000 can achieve seven operating conditions, including passenger compartment cooling, passenger compartment cooling and vehicle refrigerator 1000 cooling at the same time, vehicle refrigerator 1000 cooling, passenger compartment heating, passenger compartment heating and vehicle refrigerator 1000 cooling, passenger compartment dehumidification and passenger compartment defogging. Among them, passenger compartment cooling or heating and vehicle refrigerator 1000 are independent of each other, have no interaction, and do not affect each other.

[0147] In addition, the thermal management system 2000 can also be used to cool the vehicle's power battery.

[0148] In a specific example, when the thermal management system 2000 needs to operate the passenger compartment cooling and the vehicle refrigerator 1000 cooling mode at the same time, the second solenoid valve 2184 is closed, the first solenoid valve 2183 is opened, and the first expansion valve 2185 is closed at the same time, and the second expansion valve 2186 and the third expansion valve 2210 are opened. At this time, the compressor 2130 discharges high-temperature and high-pressure refrigerant after compression, and the refrigerant flows through the in-vehicle condenser 2140. At this time, the in-vehicle condenser 2140 only serves as a flow channel and does not exchange heat with the refrigerant, so that the in-vehicle condenser The outlet of the condenser 2140 is still a high-temperature and high-pressure refrigerant. The outlet of the in-vehicle condenser 2140 is connected to the external heat exchanger 2150 through the first solenoid valve 2183. The refrigerant exchanges heat with the environment through the external heat exchanger 2150 to reduce the refrigerant temperature, so that the refrigerant discharged through the outlet of the external heat exchanger 2150 is a medium-temperature and high-pressure fluid, which may be a liquid or a gas, depending on the ambient temperature. At this time, the refrigerant forms two branches after passing through the external heat exchanger 2150. The first branch is connected to the second expansion valve 2186. The refrigerant After throttling and cooling by the second expansion valve 2186, it becomes low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the second expansion valve 2186 is connected to the evaporator 2160 in the vehicle. At this time, the refrigerant is cooled to low-temperature air and provided to the vehicle for cooling, thereby achieving the purpose of cooling the passenger compartment. At the same time, the outlet of the evaporator 2160 in the vehicle is connected to the gas-liquid separator 2170. The gas-liquid separator 2170 separates the gaseous refrigerant and the liquid refrigerant. The gas-liquid separator 2170 can serve as an intermediate storage of the gaseous refrigerant to ensure the stability of the compressor suction. The second branch It is connected to the third expansion valve 2210. The refrigerant is throttled and cooled by the third expansion valve 2210 to become low-temperature and low-pressure wet steam or supercooled liquid. The outlet of the third expansion valve 2210 is connected to the heat exchange component 200. At this time, the heat exchange component 200 acts as an evaporator, taking away the heat in the refrigerator 110 to achieve the purpose of cooling the vehicle refrigerator 1000. The refrigerant at the outlet of the heat exchange component 200 is a low-temperature and low-pressure fluid. Finally, the air-conditioning flow path merges with the outlet of the heat exchange component 200 and returns to the compressor 2130, thereby forming a cycle.
