Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated compartments, in particular to a refrigerated compartment rear door panel and a refrigerated compartment. Background Art

[0002] Refrigerated trucks, also known as insulated trucks, refer to closed van transport trucks used to maintain the temperature of frozen or fresh goods. They can be classified according to manufacturer, chassis carrying capacity, and compartment type. The body of the refrigerated truck is equipped with insulation materials, and the interior is equipped with cooling devices, heating devices, temperature measuring devices, and ventilation devices. It has three functions: refrigeration, insulation, and heating. Refrigerated trucks include mechanical refrigerated trucks, cold plate refrigerated trucks, liquid nitrogen refrigerated trucks, and dry ice refrigerated trucks. Mechanical refrigerated trucks are the main type. Their refrigeration system consists of a compressor, condenser, expansion valve, and evaporator. The working principle is steam compression refrigeration. Refrigerated trucks are often used to transport frozen foods, dairy products, vegetables and fruits, vaccines, and medicines, so that the healthy quality of all kinds of food can be maintained.

[0003] For example, a Chinese patent (CN214874169U) discloses a sealing device for a rear door panel of a refrigerated compartment, which includes a first sealing strip, a first sealing mechanism, and a second sealing mechanism. The first sealing strip is fixedly arranged on the peripheral side of the rear door panel, the first sealing mechanism is arranged on the rear door panel, the first sealing mechanism connects the first sealing strip and the upper and lower sides of the compartment, the second sealing mechanism is arranged on the rear door panel, and the first sealing mechanism connects the first sealing strip on the rear door panel close to another rear door panel. This application seals the contact position between the rear door panel and the upper and lower sides of the refrigerated compartment and the connection position between the rear door panels by setting the first sealing mechanism and the second sealing mechanism, thereby enhancing the sealing of the rear door panel of the refrigerated compartment and achieving a better refrigeration effect.

[0004] The above scheme still has the following technical deficiencies. The above scheme is to seal the rear door panel when it is closed, but when it is necessary to unload or load the goods, the rear door panel needs to be opened. At this time, the cold air inside the refrigerated compartment will leak out from the upper and lower gaps between the refrigerated compartment main body and the rear door panel. At this time, the cold air consumption is very large. Based on this, a refrigerated compartment rear door panel and a refrigerated compartment are proposed. Utility Model Content
