[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.
[0024] The vehicle-mounted refrigerator provided in this application embodiment, such as Figure 2 and Figure 3 As shown, the device includes a main body 100, an air-cooled refrigeration component 310, and a direct-cooling refrigeration component. The main body 100 has a refrigeration chamber 200, an installation chamber 311, and an air vent. The air-cooled refrigeration component 310 includes an air-cooled heat exchanger 312, which is located in the installation chamber 311. The air vent connects the refrigeration chamber 200 and the installation chamber 311. The direct-cooling refrigeration component includes a direct-cooling heat exchanger 321, which is located on the wall of the refrigeration chamber 200.
[0025] In this vehicle-mounted refrigerator, the direct-cooling refrigeration component exchanges heat with the refrigerant placed in the refrigeration chamber 200 via conduction (i.e., thermal conduction) through the direct-cooling heat exchanger 321, ensuring rapid cooling. The air-cooling refrigeration component 310 blows cool air onto the refrigerant placed in the refrigeration chamber 200 through convection (i.e., thermal convection) of air passing through the air-cooling heat exchanger 312, ensuring good temperature uniformity in the refrigeration chamber 200. Therefore, the vehicle-mounted refrigerator provided in this application not only has a rapid cooling speed but also good temperature uniformity in the refrigeration chamber 200.
[0026] It is possible that the direct-cooling heat exchanger 321 and the air-cooling heat exchanger 312 are connected in series; or it is possible that the direct-cooling heat exchanger 321 and the air-cooling heat exchanger 312 are connected in parallel, etc.; all of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model, so they will not be elaborated here, and all should fall within the protection scope of this application.
[0027] In some examples, such as Figure 2 and Figure 3As shown, the air-cooled refrigeration component 310 also includes a fan 315, which is located at the air vent. Under the action of the fan 315, the air in the mounting chamber 311 that has passed through the air-cooled heat exchanger 312 quickly enters the refrigeration chamber 200 and blows cold air on the refrigerant placed in the refrigeration chamber 200, so that the temperature uniformity of the refrigeration chamber 200 is better.
[0028] In some embodiments, the air vent includes an air inlet and an air outlet, with the air-cooled heat exchanger 312 located between the air inlet and the air outlet, and the fan 315 positioned at the air outlet (or alternatively, the fan 315 positioned at the air inlet). Under the action of the fan 315, air from the cooling chamber 200 enters the mounting chamber 311 through the air inlet, then passes through the air-cooled heat exchanger 312, and is blown back into the cooling chamber 200 from the air outlet, achieving continuous air circulation between the cooling chamber 200 and the mounting chamber 311. This further improves the temperature uniformity of the cooling chamber 200.
[0029] In some embodiments, such as Figure 2 and Figure 3 As shown, the air-cooled heat exchanger 312 is configured as a finned heat exchanger.
[0030] In some examples, such as Figure 2 As shown, the cavity wall of the refrigeration chamber 200 includes a direct cooling heat exchanger 321 (i.e., the direct cooling heat exchanger 321 is part of the cavity wall of the refrigeration chamber 200), and the edge of the direct cooling heat exchanger 321 is directly or indirectly connected to the cavity wall of the mounting chamber 311. The heat exchange surface of the direct cooling heat exchanger 321 is exposed to the inside of the refrigeration chamber 200. In this way, the heat exchange surface of the direct cooling heat exchanger 321 exchanges heat with the refrigerant placed in the refrigeration chamber 200 by conduction. Therefore, the direct cooling heat exchanger 321 cools the refrigerant placed in the refrigeration chamber 200 faster. Moreover, the assembly process of the direct cooling heat exchanger 321 is eliminated in the vehicle refrigerator, so the assembly process of the vehicle refrigerator is also simpler.
[0031] In some embodiments, such as Figure 1 and Figure 2 As shown, the main body 100 includes an inner liner 110, a partition 314, and a shell 120. The inner liner 110 is located inside the shell 120. The partition 314 is erected inside the inner liner 110 and divides the interior of the inner liner 110 into a refrigeration chamber 200 and an installation chamber 311. The air inlet and outlet are both located on the partition 314. In this design, the inner liner 110 includes a direct-cooling heat exchanger 321, meaning the direct-cooling heat exchanger 321 is part of the inner liner 110 and is an integral structure with it. Therefore, the cavity wall of the refrigeration chamber 200 includes the partition 314 and the direct-cooling heat exchanger 321. Figure 2As shown, the direct-cooling heat exchanger 321 is configured as a blown heat exchanger. The arrangement of the blown heat exchanger can be reasonably designed by those skilled in the art as needed, and will not be elaborated here.
[0032] In other examples, such as Figure 3 As shown, the cavity wall of the refrigeration chamber 200 includes a first wall panel 322. The edge of the first wall panel 322 is directly or indirectly connected to the cavity wall of the mounting chamber 311. The direct-cooling heat exchanger 321 is disposed on the first wall panel 322 and abuts against the surface of the first wall panel 322 (i.e., the first wall panel 322 is part of the cavity wall of the refrigeration chamber 200, and the direct-cooling heat exchanger 321 is not part of the cavity wall of the refrigeration chamber 200; the direct-cooling heat exchanger 321 is only disposed on the first wall panel 322). Figure 1 and Figure 3 As shown, the main body 100 includes an inner liner 110, a partition 314, and a shell 120. The inner liner 110 is located inside the shell 120. The partition 314 is erected inside the inner liner 110 and divides the interior of the inner liner 110 into a refrigeration chamber 200 and an installation chamber 311. The air inlet and air outlet are both located on the partition 314. In this design, the inner liner 110 includes a first wall panel 322 but does not include the direct cooling heat exchanger 321. That is, the first wall panel 322 is part of the inner liner 110, while the direct cooling heat exchanger 321 is a separate structure from the inner liner 110 and is not part of the inner liner 110. Therefore, the cavity wall of the refrigeration chamber 200 includes the partition 314 and the first wall panel 322, but does not include the direct cooling heat exchanger 321.
[0033] Alternatively, the direct-cooling heat exchanger 321 can be located on the side of the first wall panel 322 facing away from the interior of the refrigeration chamber 200, such that the heat exchange surface of the direct-cooling heat exchanger 321 is attached to the surface of the first wall panel 322 facing away from the interior of the refrigeration chamber 200; or it can be, for example... Figure 3 As shown, the direct-cooling heat exchanger 321 is located on the side of the first wall panel 322 facing the interior of the refrigeration chamber 200. If the direct-cooling heat exchanger 321 is attached to the surface of the first wall panel 322 facing the interior of the refrigeration chamber 200, the heat exchange surface of the direct-cooling heat exchanger 321 faces the interior of the refrigeration chamber 200. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this utility model. They will not be repeated here, and should all fall within the protection scope of this application.
[0034] Alternatively, the process of this solution is simple, and the direct cooling heat exchanger 321 is a plate-tube heat exchanger; or the direct cooling heat exchanger 321 is a blown heat exchanger, etc.; all of the above can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model, so they will not be elaborated here, and all should fall within the protection scope of this application.
[0035] In some examples, such as Figures 1 to 3As shown, the main body 100 has an opening, and a door 400 is installed at the opening.
[0036] The vehicle provided in this application embodiment (not shown in the figure) includes the vehicle refrigerator described in any of the above embodiments.
[0037] This vehicle possesses all the advantages of the vehicle-mounted refrigerator provided in any of the above embodiments, which will not be repeated here.
[0038] In summary, the technical solution provided in this application embodiment allows the direct-cooling refrigeration component to exchange heat with the refrigerant placed in the refrigeration chamber through conduction via a direct-cooling heat exchanger, thus ensuring a fast cooling speed for the refrigerant. The air-cooling refrigeration component blows cold air onto the refrigerant placed in the refrigeration chamber through convection via air passing through the air-cooling heat exchanger, thus ensuring good temperature uniformity in the refrigeration chamber. Therefore, the vehicle refrigerator provided in this application not only has a fast cooling speed for the refrigerant but also good temperature uniformity in the refrigeration chamber.
