Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a refrigerator and a vehicle. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It cools the internal environment through refrigeration components. These components generate heat during the cooling process, and this heat needs to be dissipated effectively and promptly to maintain normal operation.

[0003] In related technologies, heat generated by a cooling component is dissipated through an air-cooled assembly. This assembly includes a radiator and a fan. The radiator is connected to the cooling component and absorbs the heat generated. The fan is positioned on one side of the radiator and blows airflow through the radiator's heat dissipation channels, allowing the absorbed heat to dissipate outwards. However, this method of cooling with a fan on only one side of the radiator has relatively low heat dissipation efficiency. Utility Model Content

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0039] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0040] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] In related technologies, a heat sink includes a heat-conducting plate and multiple heat dissipation fins. The fins are connected to the heat-conducting plate, and a heat dissipation channel is defined between each pair of adjacent heat-conducting plates. This channel has an inlet and an outlet. A fan is positioned at the inlet and blows airflow into the heat dissipation channel. As the airflow passes through the channel, it exchanges heat with the heat dissipation fins and carries away their heat. Alternatively, a fan is positioned at the end of the heat dissipation fins furthest from the heat-conducting plate and draws airflow from the heat dissipation channel. As the airflow is drawn in, it exchanges heat with the heat dissipation fins and carries away their heat. In both of these cases, the fan is positioned on one side of the heat sink, resulting in relatively low heat dissipation efficiency.

[0042] In addition, to improve heat dissipation efficiency, some methods involve installing two or more fans side-by-side on one side of the radiator. Each fan corresponds to the air intake of a different heat dissipation channel and is used to blow or draw air into that channel. However, this requires the radiator to be larger to accommodate the two or more fans, resulting in increased radiator weight and space occupation, and complicating the refrigerator's structural layout.

[0043] In view of this, the present invention provides a refrigerator 100 that can improve heat dissipation efficiency. The following is in conjunction with... Figures 1 to 6 The structure of the refrigerator 100 according to an embodiment of the present utility model will be described in detail.

[0044] like Figures 1 to 3 As shown, the refrigerator 100 includes a cabinet 10, a refrigeration component 20 and an air-cooling component 30. The refrigeration component 20 is connected to the cabinet 10 and the air-cooling component 30 respectively. The refrigeration component 20 is used to refrigerate the cabinet 10, and the air-cooling component 30 is used to dissipate heat from the refrigeration component 20.

[0045] like Figure 4 As shown, the refrigeration component 20 has a cold end 210 and a hot end 220. The cold end 210 is connected to the housing 10 and is used to refrigerate the housing 10. The hot end 220 is connected to the air-cooling component 30 and is used to cool the hot end 220.

[0046] like Figure 5and Figure 6 As shown, the air-cooled assembly 30 includes a radiator 31, a first fan 32, and a second fan 33. The radiator 31 is connected to the hot end 220 and defines a heat dissipation channel 301. The heat dissipation channel 301 has a first air inlet 3011 and a first air outlet 3012. The first fan 32 is located at the first air inlet 3011, and the second fan 33 is located at the first air outlet 3012. The first fan 32 is used to blow airflow into the heat dissipation channel 301, and the second fan 33 is used to draw airflow from the heat dissipation channel 301.

[0047] During operation, the cold end 210 connected to the cabinet 10 absorbs heat, thereby achieving a cooling effect on the cabinet 10. Correspondingly, the hot end 220 releases heat. At the same time, the radiator 31 absorbs the heat released by the hot end 220 and dissipates the absorbed heat outward through the airflow of the first fan 32 and the second fan 33, thereby achieving cooling and heat dissipation of the refrigerator 100.

[0048] In this embodiment of the present invention, a first fan 32 and a second fan 33 are respectively provided at the first air inlet 3011 and the first air outlet 3012 of the heat dissipation channel 301. During operation, the first fan 32 can blow airflow into the heat dissipation channel 301 and generate positive pressure at the first air inlet 3011. At the same time, the second fan 33 can draw airflow from the heat dissipation channel 301 and generate negative pressure at the first air outlet 3012. The synergistic effect of positive and negative pressure can generate a large pressure gradient in the heat dissipation channel 301 and form a strong convection effect. In this way, the airflow can pass through the heat dissipation channel 301 at a large speed and a large flow rate, and exchange heat with the radiator 31 to remove the heat from the radiator 31, thereby improving the heat exchange efficiency between the airflow and the radiator 31, thus improving the heat dissipation efficiency of the air-cooled component 30, so that the heat generated by the hot end 220 can be dissipated to the outside in a timely and effective manner through the air-cooled component 30.

[0049] Furthermore, compared to the method of arranging two or more fans side by side on one side of the radiator 31, the refrigerator 100 of this utility model embodiment adopts the method of arranging fans on both sides of the radiator 31 respectively (that is, a first fan 32 and a second fan 33 are respectively arranged at the first air inlet end 3011 and the first air outlet end 3012 of the heat dissipation channel 301). While improving the heat dissipation efficiency of the air-cooling component 30, the structural size of the radiator 31 can be set to be smaller and adapted to the two fans on both sides, making the structure of the air-cooling component 30 more compact, with less weight and space occupation, and a simpler structural layout, reducing the structural layout difficulty and cost of the air-cooling component 30.

[0050] like Figure 6As shown, in some embodiments, the heat sink 31 includes a heat-conducting plate 311 and a plurality of heat dissipation fins 312. The heat-conducting plate 311 is connected to the hot end 220, and the plurality of heat dissipation fins 312 are respectively connected to the side of the heat-conducting plate 311 facing away from the hot end 220. A heat dissipation channel 301 is defined between each pair of adjacent heat dissipation fins 312. The heat dissipation channel 301 has the aforementioned first air inlet 3011 and first air outlet 3012. A first fan 32 is disposed at one end of the plurality of heat dissipation fins 312 and opposite to the first air inlet 3011. A second fan 33 is disposed at the other end of the plurality of heat dissipation fins 312 and opposite to the first air outlet 3012. When the first fan 32 and the second fan 33 are started, they exchange heat with the heat dissipation fins 312 through the airflow in the heat dissipation channel 301 and remove the heat from the heat dissipation fins 312.

[0051] like Figure 5 and Figure 6 As shown, in some embodiments, the air-cooled assembly 30 further includes an air guide shroud 34, which defines a receiving cavity 302, an air inlet 303, and an air outlet 304. The air inlet 303 and the air outlet 304 are respectively connected to the receiving cavity 302. The radiator 31, the first fan 32, and the second fan 33 are all housed in the receiving cavity 302. The first fan 32 is located between the first air inlet end 3011 and the air inlet 303, and the second fan 33 is located between the first air outlet end 3012 and the air outlet 304.

[0052] During operation, the first fan 32 generates negative pressure at the air inlet 303, causing air outside the air inlet 303 to be drawn into the accommodating cavity 302 through the air inlet 303 and form an airflow. Under the action of the wind force of the first fan 32 and the second fan 33, the airflow passes through the heat dissipation channel 301 and is discharged to the outside through the air outlet 304.

[0053] In this embodiment, by setting the air guide shroud 34 and accommodating the radiator 31, the first fan 32, and the second fan 33 in the accommodating cavity 302, the radiator 31, the first fan 32, and the second fan 33 are isolated from the outside. In this way, the first fan 32 and the second fan 33 can generate greater air pressure in the accommodating cavity 302, reducing the pressure relief of the first fan 32 and the second fan 33. Moreover, the air guide shroud 34 can concentrate the airflow and guide it to the heat dissipation channel 301, which helps to improve the heat dissipation efficiency of the air-cooled component 30.

[0054] In certain usage environments, the refrigerator 100 may be installed close to the user's location. The airflow generated by the first fan 32 and the second fan 33 may interfere with the user. For example, when the refrigerator 100 is installed in the cabin of a vehicle, its installation position may be close to the left and right seats, with the air inlet 303 and the air outlet 304 facing the left and right seats respectively. If the airflow directly enters the first air intake 3011 from the air inlet 303 in a horizontal direction, or directly blows out of the air outlet 304 from the second air intake 3012 in a horizontal direction, then when the first fan 32 generates negative pressure at the air inlet 303, airflow may be generated on the skin surface of the user in the seat corresponding to the air inlet 303. When the second fan 33 blows air out of the air outlet 304, the airflow may flow directly to the skin surface of the user in the seat corresponding to the air outlet 304, affecting the user experience.

[0055] Therefore, in some embodiments, the air guide shroud 34 includes a shroud 341, an air inlet 342, and an air outlet 343. The air inlet 342 and the air outlet 343 are respectively connected to the shroud 341. The shroud 341 defines the aforementioned accommodating cavity 302, the air inlet 342 defines the aforementioned air inlet 303, and the air outlet 343 defines the aforementioned air outlet 304.

[0056] The air inlet 342 is bent relative to the cover 341, and the air inlet 303 is located at the end of the air inlet 342 away from the cover 341. In this way, the air inlet 303 is changed, which can prevent the air inlet 303 from facing the user's body directly. The airflow enters the first air intake end 3011 from the air inlet 303 along the bending direction of the air inlet 342. This avoids the generation of airflow on the user's skin surface near the air inlet 303 when negative pressure is generated at the air inlet 303, reduces the interference of airflow to the user at the air inlet 303, and improves the user experience.

[0057] In some embodiments, the air outlet 343 is bent relative to the cover 341, and the air outlet 304 is located at the end of the air outlet 343 away from the cover 341. In this way, the air outlet position of the air outlet 304 is changed, which can prevent the air outlet 304 from directly facing the user's body. The airflow is blown out of the air outlet 304 from the second air inlet end 3012 along the bending direction of the air outlet 343, thereby avoiding the airflow from flowing directly to the user's skin surface near the air outlet 304, reducing the interference caused by the airflow at the air outlet 304 to the user, and improving the user experience.

[0058] In some embodiments, the air inlet 342 is bent downward relative to the cover 341, and the air outlet 343 is bent downward relative to the cover 341, which can make the air inlet 303 and the air outlet 304 closer to the bottom of the refrigerator 100, reducing the interference of airflow to the user at the air inlet 303 and the air outlet 304.

[0059] Furthermore, the air inlet 303 and the air outlet 304 are oriented away from each other, so that the air inlet 303 and the air outlet 304 are oriented in a horizontal or roughly horizontal direction. This avoids the air inlet 303 and the air outlet 304 directly facing the ground or the vehicle floor, thereby preventing the airflow at the air inlet 303 and the air outlet 304 from causing dust to the ground or the vehicle floor, and further improving the user experience.

[0060] When the refrigerator 100 is installed in the vehicle cabin, the height of the air inlet 303 is lower than the height of the seat cushion, and the height of the air outlet 304 is lower than the height of the seat cushion.

[0061] like Figure 3 and Figure 4 As shown, in some embodiments, the refrigerator 100 further includes a water-cooling component 40, which is connected to the hot end 220 and the radiator 31 respectively. The water-cooling component 40 is used to absorb and dissipate heat from the hot end 220. Thus, the heat generated by the hot end 220 can be diffused sequentially to the water-cooling component 40 and the air-cooling component 30. Part of the heat diffused to the water-cooling component 40 can be directly dissipated to the outside through the water-cooling function of the water-cooling component 40, and part can be diffused to the air-cooling component 30 through the water-cooling component 40 and dissipated to the outside through the air-cooling function of the air-cooling component 30, thereby improving the heat dissipation effect of the hot end 220 and enabling the heat generated by the hot end 220 to be dissipated to the outside in a timely and effective manner.

[0062] In addition, by setting up the water-cooling component 40, the air-cooling pressure of the air-cooling component 30 can be reduced. The air-cooling component 30 does not need to use a large-volume heat sink 31 for air cooling, which makes the overall structure of the air-cooling component 30 more compact, with less weight and space occupation, and a simpler structural space layout, reducing the difficulty and cost of the structural layout of the air-cooling component 30.

[0063] like Figure 3 As shown, in some embodiments, the water-cooling assembly 40 includes a water-cooling plate 41 and a water-cooling pipe 42. The opposite sides of the water-cooling plate 41 are connected to the hot end 220 and the radiator 31, respectively. The water-cooling plate 41 defines a water-cooling cavity 401, and the water-cooling pipe 42 communicates with the water-cooling cavity 401. The water-cooling cavity 401 is used for supplying coolant flow, and the water-cooling pipe 42 is used for supplying coolant into or out of the water-cooling cavity 401, so that the water-cooling cavity 401 has a circulating coolant. The heat generated by the hot end 220 can diffuse sequentially to the water-cooling plate 41 and the radiator 31. During this process, the coolant flowing through the water-cooling plate 41 can exchange heat with the water-cooling plate 41 and carry away some heat. The residual heat on the water-cooling plate 41 diffuses to the radiator 31 and is dissipated by the radiator 31.

[0064] In this embodiment, the large heat capacity of the liquid is utilized to conduct heat to the hot end 220 more effectively, so that the heat generated by the hot end 220 can be quickly conducted to the water-cooled plate 41 and dissipated by the water-cooling component 40 and the air-cooling component 30, thereby improving the heat conduction efficiency and heat dissipation efficiency of the hot end 220.

[0065] Furthermore, by placing the water-cooled plate 41 between the hot end 220 and the radiator 31, the structure between the cooling component 20, the air-cooled component 30 and the water-cooled component 40 can be made more compact, reducing space occupation.

[0066] like Figure 3 and Figure 4 As shown, in some embodiments, the cooling assembly 20 includes a semiconductor cooler 21 and a conductor 22. The semiconductor cooler 21 has the aforementioned cold end 210 and the aforementioned hot end 220. The conductor 22 is connected to the cold end 210 and the housing 10, respectively. When the semiconductor cooler 21 is working, it absorbs heat from the conductor 22, causing the conductor 22 to be in a low-temperature state. The conductor 22 in the low-temperature state can exchange heat with the housing 10, thereby achieving cooling of the housing 10.

[0067] In this embodiment, by setting a conductor 22 connected to the housing 10, the low temperature effect generated by the cold end 210 can be effectively transferred to the housing 10, thereby improving its cooling efficiency for the housing 10.

[0068] In some embodiments, the housing 10 defines a storage cavity 101, and the conductor 22 defines a cooling channel 201. The cooling channel 201 communicates with the storage cavity 101 and has a second air inlet 2011 and a second air outlet 2012. The cooling assembly 20 also includes a third fan 23. The third fan 23 is provided at the second air inlet 2011 and is used to blow airflow into the cooling channel 201 so that the airflow flows into the storage cavity 101. And / or, the third fan 23 is provided at the second air outlet 2012 and is used to draw airflow from the cooling channel 201 so that the airflow flows into the storage cavity 101. With the above arrangement, a cold airflow can be formed in the cooling channel 201 and can flow into the storage cavity 101, thereby achieving a better cooling effect on the housing 10.

[0069] like Figure 4As shown, in some embodiments, the third fan 23 is a centrifugal fan, which is located at the second air inlet 2011. The air inlet of the centrifugal fan is located on the axial direction of the impeller of the centrifugal fan, and the air outlet of the centrifugal fan is located on the radial direction of the impeller of the centrifugal fan. The air outlet of the centrifugal fan is opposite to the second air inlet 2011. In this way, the space occupied by the conductor 22 and the third fan 23 can be reduced, making the structure of the conductor 22 and the third fan 23 more compact.

[0070] In some embodiments, the conductor 22 includes a conductor plate 221 and a plurality of conductor fins 222. The conductor plate 221 is connected to the cold end 210, and the plurality of conductor fins 222 are respectively connected to the side of the conductor plate 221 facing away from the cold end 210. A cooling channel 201 is defined between each pair of adjacent conductor fins 222. The cooling channel 201 has the aforementioned second air inlet 2011 and second air outlet 2012. A third fan 23 is disposed at one end of the plurality of conductor fins 222 and is opposite to the second air inlet 2011. When the third fan 23 is started, the airflow enters the cooling channel 201 through the second air inlet 2011. The airflow flowing through the cooling channel 201 exchanges heat with the conductor fins 222 to form a cold airflow, which flows out from the second air outlet 2012.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 10 includes an outer shell 11, an inner liner 12, and a door 13. A storage cavity 101 is defined within the inner liner 12, which is disposed inside the outer shell 11. A partition space 102 is defined between the inner liner 12 and the outer shell 11. The door 13 is connected to the outer shell 11 and is used to conceal or open the storage cavity 101. The conductor 22 and the third fan 23 are both located in the partition space 102, and the storage cavity 101 communicates with the partition space 102.

[0072] In this embodiment, by placing both the conductor 22 and the third fan 23 in the partition space 102, the third fan 23, in cooperation with the cooling channel 201, can form a cold airflow into the storage cavity 101 in the partition space 102. The cold airflow flows directly inside the box 10, shortening the path of the cold airflow into the storage cavity 101, thereby achieving a better cooling effect on the storage cavity 101.

[0073] like Figure 3 and Figure 4As shown, in some embodiments, the outer casing 11 defines a first opening 103 that communicates with the partition space 102, and the air guide shroud 34 defines a second opening 305 that communicates with the receiving cavity 302. The first opening 103 and the second opening 305 are opposite to and communicate with each other.
