Technical Field

[0001] This utility model relates to the field of refrigeration technology, specifically to a built-in refrigeration unit for refrigerated truck compartments. Background Technology

[0002] my country's cold chain logistics started late, and with a large population base, the per capita availability of refrigerated trucks remains very limited, lower than international standards. This indicates a broad development prospect for the refrigerated truck industry. Simultaneously, driven by consumption upgrades and guided by favorable policies, the cold chain logistics industry is developing rapidly, with cold chain transportation volume increasing year by year. Refrigerated trucks, as a crucial link in cold chain logistics, are also showing a year-on-year growth trend. Currently, my country's refrigerated trucks mainly include mechanical refrigerated trucks, cold plate refrigerated trucks, liquid nitrogen refrigerated trucks, and dry ice refrigerated trucks, with mechanical refrigerated trucks being the most prevalent. Their refrigeration systems consist of compressors, condensers, expansion valves, and evaporators.

[0003] The existing equipment has the following shortcomings when in use: the refrigeration unit of the refrigerated truck is usually installed directly above the front of the truck, lacking a protective structure. When the front of the truck needs to be turned over for maintenance, the refrigeration unit is easily bumped and it is also inconvenient to inspect the refrigeration unit installed at a high position.

[0015] Preferably, an auxiliary support rod is hinged to the bottom of the mounting base, and a handle is installed on the mounting base.

[0016] By adopting the above technical solution, after the mounting base is pulled out of the built-in groove, the auxiliary support rod will rotate and stand upright due to gravity. After tilting the mounting base, the auxiliary support rod can be rotated to support it, increasing the stability of the mounting base. It is also convenient for workers to reach out and pull out the mounting base.

[0017] Preferably, the main body of the refrigeration unit includes a compressor, an evaporator, a condenser, and an expansion valve.

[0018] Compared with the prior art, the advantages of this utility model are: it can effectively protect the main body of the refrigeration unit, and avoid collision with the refrigeration unit when the front of the vehicle needs to be turned over for maintenance, making it convenient for staff to inspect the main body of the refrigeration unit without having to climb to a high place to inspect the refrigeration unit.
