Description

Technical Field

[0001] This utility model belongs to the field of refrigerator-related technical technology, and in particular relates to a vehicle-mounted refrigerator and vehicle. Background Technology

[0002] A car refrigerator is a portable refrigeration device designed specifically for vehicles to store and keep food, beverages, and other items fresh while driving or during outdoor activities.

[0003] Currently, existing car refrigerators typically use either onboard compressor cooling or semiconductor cooling. Both methods require heat dissipation. However, current car refrigerators only offer one heat dissipation mode. Because vehicles need to cool or refrigerate according to different needs during actual driving, the heat generated by the car refrigerator cannot be used for the vehicle's heating requirements, resulting in waste.

[0004] Currently, commercially available car refrigerators mainly employ two technologies: compressor refrigeration and semiconductor refrigeration. Regardless of whether compressor or semiconductor refrigeration is used, waste heat is generated during operation, which must be dissipated through a cooling system to ensure refrigeration efficiency. However, existing car refrigerator cooling designs rely solely on passive heat dissipation, directly releasing heat into the environment without considering heat reuse. This not only increases overall vehicle energy consumption but also fails to fully realize the synergistic potential of thermal management. Utility Model Content

[0005] In view of this, it is necessary to provide a vehicle-mounted refrigerator and vehicle for solving the above-mentioned technical problems.

[0006] A vehicle-mounted refrigerator, comprising:

[0007] The enclosure is formed by enclosing a refrigeration chamber and a storage chamber. The refrigeration chamber is set independently relative to the storage chamber. The enclosure has a first air vent and a second air vent. The first air vent and the second air vent are respectively connected to the storage chamber. The first air vent is used to connect to the interior space of the vehicle, and the second air vent is used to connect to the external atmosphere.

[0008] A semiconductor cooling chip is housed in the accommodating chamber. The semiconductor cooling chip has a cold end and a hot end, and the cold end is used to provide cooling to the cooling chamber.

[0009] A cooling fan is housed within the accommodating chamber;

[0010] The cooling fan has a first working mode and a second working mode. When the cooling fan is in the first working mode, the accommodating chamber can take in air through the first air vent and take out air through the second air vent. When the cooling fan is in the second working mode, the accommodating chamber can take in air through the second air vent and take out air through the first air vent.

[0011] It is understandable that by using a cooling fan to control the air intake and exhaust of the first and second air vents, the vehicle refrigerator can have two different modes for heat dissipation of the thermoelectric cooling chip during operation. In this way, when the vehicle refrigerator is used in a vehicle, the heat generated by the vehicle refrigerator when dissipating heat from the hot end of the thermoelectric cooling chip can be used to heat the interior environment according to the vehicle's needs. This can effectively utilize the heat used for heat dissipation of the vehicle refrigerator, reduce vehicle energy consumption, and enable coordinated operation with the vehicle's thermal management system.

[0012] In one embodiment, the first air outlet is disposed on the bottom wall of the accommodating chamber; the second air outlet is disposed on the side wall of the accommodating chamber away from the cooling chamber.

[0013] Furthermore, the ventilation area of ​​the second air vent is larger than that of the first air vent.

[0014] In one embodiment, the cooling fan includes a first fan and a second fan; the first fan is disposed at the location of the second air vent, and the second fan is disposed at the location of the first air vent;

[0015] Furthermore, the rotation direction of the fan blades can be changed when the first and second fans are started.

[0016] It is understandable that using the first fan and the second fan to control the airflow of the second air vent and the first air vent respectively can promote the airflow in the room, thereby improving the heat dissipation effect of the cooling fan when dissipating heat from the hot end of the semiconductor cooling chip.

[0017] In one embodiment, the vehicle refrigerator further includes a radiator, which is housed in the accommodating chamber and thermally connected to the hot end;

[0018] Furthermore, the cooling fan can provide air cooling for the heat sink.

[0019] It is understandable that by utilizing the thermal connection between the heat sink and the hot end, the heat sink can quickly transfer the heat from the hot end of the thermoelectric cooler and increase the contact area with the cold air in the airflow path, thus further improving the heat dissipation effect of the cooling fan when dissipating heat from the hot end of the thermoelectric cooler.

[0020] In one embodiment, the cooling fan includes a first fan and a second fan, the first fan being mounted on one end face of the radiator facing the second air vent; the second fan being mounted on the bottom face of the radiator facing the first air vent.

[0021] In one embodiment, the size of the first fan is larger than the size of the second fan;

[0022] Furthermore, the number of the first fan is configured to be one; the number of the second fan is configured to be multiple, and the multiple second fans are arranged side by side along the length of the heat sink.

[0023] In one embodiment, the housing is provided with a metal inner liner, which encloses and forms the refrigeration chamber;

[0024] Furthermore, the cold end is connected to the metal inner liner and is thermally connected to the metal inner liner.

[0025] It is understandable that the cold end of the semiconductor cooling chip provides cooling to the cooling chamber of the metal liner through direct cooling, which can improve the uniformity of cooling distribution within the cooling chamber.

[0026] In one embodiment, the housing is provided with a heat insulation board, and the refrigeration compartment and the accommodating compartment are separated by the heat insulation board.

[0027] It is understandable that using an insulation board to separate the cooling room from the storage room allows the insulation board to insulate the cooling room from the storage room, preventing the cooling capacity of the cooling room from being affected by the heat of the storage room.

[0028] This application also seeks protection for a vehicle, including the vehicle body and the aforementioned vehicle refrigerator;

[0029] The second air vent is connected to the interior space of the vehicle body, and the first air vent is able to connect with the external atmosphere through the vehicle body.

[0030] It is understandable that by utilizing the connection between the second air vent on the vehicle refrigerator and the interior space of the vehicle body, the heat generated by the vehicle refrigerator during heat dissipation can be provided to the interior space of the vehicle body or directly exhausted into the external atmosphere as needed.

[0031] In one embodiment, the vehicle body has an installation station located between the driver and passenger seats of the vehicle;

[0032] The vehicle-mounted refrigerator is installed at the installation station.

[0033] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0034] The vehicle-mounted refrigerator and vehicle claimed in this application utilize a cooling fan to control the air intake and exhaust of a first air vent and a second air vent, enabling the vehicle-mounted refrigerator to operate in two different modes for heat dissipation of the thermoelectric cooling chip. Thus, when the vehicle-mounted refrigerator is applied to a vehicle, the heat generated by the refrigerator dissipating heat from the hot end of the thermoelectric cooling chip can be used to heat the interior environment according to the vehicle's needs, thereby achieving effective utilization of the heat used for heat dissipation by the vehicle-mounted refrigerator, reducing vehicle energy consumption, and enabling coordinated operation with the vehicle's thermal management system.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] like Figure 1 , Figure 2 As shown, the vehicle refrigerator 100 provided in this application includes a cabinet 10, a semiconductor cooling chip 20, and a cooling fan 30. The cabinet 10 encloses a cooling chamber 11 and a housing chamber 12. The cooling chamber 11 is independently arranged relative to the housing chamber 12. A first air vent 101 and a second air vent 102 are provided on the cabinet 10. The first air vent 101 and the second air vent 102 are respectively connected to the housing chamber 12. The first air vent 101 is used to connect to the interior space of the vehicle, and the second air vent 102 is used to connect to the external atmosphere. The semiconductor cooling chip 20 is housed in the housing chamber 30. Inside compartment 12, the thermoelectric cooler 20 has a cold end 21 and a hot end 22. The cold end 21 is used to provide cooling to the cooling compartment 11. A cooling fan 30 is housed within the compartment 12. The cooling fan 30 has a first operating mode and a second operating mode. When the cooling fan 30 is in the first operating mode, the compartment 12 can receive air through the first air vent 101 and receive air through the second air vent 102. When the cooling fan 30 is in the second operating mode, the compartment 12 can receive air through the second air vent 102 and receive air through the first air vent 101. In other words, the airflow direction for cooling the hot end 22 of the thermoelectric cooler 20 in the vehicle refrigerator 100 of this application can be adjusted.

[0044] As can be seen from the above, when the vehicle refrigerator 100 of this application is working, the cooling fan 30 is used to control the air intake and exhaust of the first air vent 101 and the second air vent 102, so that the vehicle refrigerator 100 has two different modes for heat dissipation of the semiconductor cooling chip 20 during operation. In this way, when the vehicle refrigerator 100 is applied to a vehicle, the heat from the vehicle refrigerator 100 dissipating heat from the hot end 22 of the semiconductor cooling chip 20 can be used to heat the interior environment of the vehicle according to the needs of the vehicle, thereby realizing the effective utilization of the heat dissipation of the vehicle refrigerator 100, reducing vehicle energy consumption, and realizing coordinated operation with the vehicle thermal management system.

[0045] It should be noted that when the vehicle interior needs heating, the vehicle refrigerator 100 of this application controls the airflow direction of the hot end 22 of the semiconductor cooling chip 20 for heat dissipation through the cooling fan 30, so that the vehicle refrigerator 100 can blow hot air into the vehicle interior to meet the heating needs of the vehicle interior; when the vehicle interior does not need heating or needs cooling, the vehicle refrigerator 100 of this application changes the airflow direction of the cooling fan 30 for heat dissipation of the hot end 22 of the semiconductor cooling chip 20, so that the vehicle refrigerator 100 can blow hot air out of the vehicle.

[0046] like Figure 2 As shown, in one embodiment, a metal inner liner 13 is provided on the housing 10, and the metal inner liner 13 encloses a cooling chamber 11; and the cold end 21 of the semiconductor cooling chip 20 is connected to the metal inner liner 13 and thermally connected to the metal inner liner 13. That is to say, in this embodiment, the cold end 21 of the semiconductor cooling chip 20 provides cooling to the cooling chamber 11 of the metal inner liner 13 through direct cooling. Specifically, when the semiconductor cooling chip 20 is working, the cold end 21 can first transfer the cooling to the metal inner liner 13. Utilizing the overall thermal conductivity of the metal inner liner 13, the metal inner liner 13 can quickly transfer the cooling to various positions in the cooling chamber 11, thereby improving the uniformity of the cooling distribution in the cooling chamber 11. It is understood that in other embodiments, the cold end 21 of the semiconductor cooling chip 20 can also be thermally connected to the metal inner liner 13 through a heat-conducting block, or the cold end 21 of the semiconductor cooling chip 20 can be disposed on part of the chamber wall of the cooling chamber 11, which will not be elaborated here.

[0047] like Figure 2As shown, in one embodiment, a heat insulation plate 14 is provided on the cabinet 10, separating the refrigeration compartment 11 from the storage compartment 12. That is, the vehicle refrigerator 100 of this embodiment can use the heat insulation plate 14 to insulate the refrigeration compartment 11 from the storage compartment 12, thus preventing the cooling capacity of the refrigeration compartment 11 from being affected by the heat of the storage compartment 12. Here, the heat insulation plate 14 is located on the periphery of the cold end 21 and serves to insulate the cold end 21. It should be noted that the aforementioned heat insulation plate 14 can be a conventional insulation layer of existing refrigerators, which will not be elaborated upon here.

[0048] like Figure 2 As shown in this application, the first air vent 101 is disposed on the bottom wall 121 of the accommodating chamber 12, and the second air vent 102 is disposed on the side wall 122 of the accommodating chamber 12 away from the refrigeration chamber 11. Furthermore, the ventilation area of ​​the second air vent 102 is larger than that of the first air vent 101. Here, the second air vent 102 is used to communicate with the interior space of the vehicle equipped with the vehicle refrigerator 100, and the first air vent 101 is used to communicate with the outside atmosphere.

[0049] like Figure 2 , Figure 3 As shown, in one embodiment, the cooling fan 30 includes a first fan 31 and a second fan 32; the first fan 31 is located at the first air vent 101, and the second fan 32 is located at the second air vent 102; furthermore, the rotation direction of the fan blades of the first fan 31 and the second fan 32 can be changed when they are started. That is, in this embodiment, the first fan 31 and the second fan 32 can be used to control the airflow into and out of the first air vent 101 and the second air vent 102 respectively, specifically by controlling the forward or reverse rotation of the first fan 31 and the second fan 32. This promotes airflow within the accommodating chamber 12, thereby improving the cooling effect of the cooling fan 30 when dissipating heat from the hot end 22 of the semiconductor cooling chip 20. It is understood that in other embodiments, the cooling fan 30 may also have only one fan, which can be located at the first air vent 101, the second air vent 102, or within the accommodating chamber 12, depending on the usage requirements; this will not be elaborated upon here.

[0050] like Figure 2 , Figure 3As shown, in this embodiment, the vehicle refrigerator 100 also includes a radiator 40, which is housed within the accommodating compartment 12 and thermally connected to the hot end 22. That is, the vehicle refrigerator 100 of this embodiment can use the radiator 40 to quickly transfer heat from the hot end 22 of the thermoelectric cooler 20 and increase the contact area with the cold air in the airflow path, thus further improving the heat dissipation effect of the cooling fan 30 when dissipating heat from the hot end 22 of the thermoelectric cooler 20. It should be noted that the specific structure of the radiator 40 and the method by which the radiator 40 is thermally connected to the hot end 22 of the thermoelectric cooler 20 can adopt conventional methods of the prior art, and will not be elaborated here.

[0051] like Figure 2 As shown, in this embodiment, the first fan 31 is mounted on one end face 41 of the heat sink 40 facing the second air vent 102, and the second fan 32 is mounted on the bottom face 42 of the heat sink 40 facing the first air vent 101. Here, the size of the first fan 31 is larger than the size of the second fan 32; and the number of first fans 31 is configured as one; the number of second fans 32 is configured as multiple, and the multiple second fans 32 are arranged side by side in the length direction X of the heat sink.

[0052] In addition, this application also provides a vehicle, including a vehicle body (not shown) and the aforementioned vehicle-mounted refrigerator 100, wherein the second air vent 102 of the vehicle-mounted refrigerator 100 is connected to the interior space of the vehicle body, and the first air vent 101 is connected to the external atmosphere through the vehicle body. This allows the heat from the vehicle-mounted refrigerator 100 during heat dissipation to be provided to the interior space of the vehicle body or directly exhausted to the external atmosphere as needed. It should be noted that the first air vent 101 of the aforementioned vehicle-mounted refrigerator 100 is specifically connected to the external atmosphere through a ventilation duct installed on the vehicle body, but since this is not the focus of this application, it will not be elaborated here.

[0053] In one embodiment, the vehicle body has an installation station (not shown), which is located between the driver and passenger seats, and the vehicle refrigerator 100 is installed at the installation station. That is, in this embodiment, the vehicle refrigerator 100 is installed in the location of the existing armrest box on the vehicle.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
