[0002] Refrigerated cars are usually made of high-quality materials such as stainless steel and polyurethane, and have the characteristics of good thermal insulation, lightness, and high strength. During the transportation and distribution of food, due to factors such as long distances and temperature changes, food is prone to spoilage and decay. Refrigerated food cars can ensure that food is always kept at a constant low temperature during transportation, maintaining the freshness and quality of the food.

[0003] Chinese utility model patent CN216232615U discloses a heat-insulating refrigerated truck compartment for food transportation, including a compartment body, a heat-insulating structure, a cargo rack, a box door and a reflective heat-insulating coating, wherein the heat-insulating structure is arranged on the inner wall of the compartment body, the cargo rack is arranged on the inner walls on both sides of the compartment body, two groups of cargo racks are arranged, a refrigeration unit is installed on the top of the compartment body, the box door is installed on the outer wall of one side of the compartment body through a hinge, and a handle is installed on the surface of the box door, a cavity is arranged in the side wall of the compartment body, and a vacuum heat-insulating panel is fixed inside the cavity, and the reflective heat-insulating coating is evenly sprayed on the outer wall of the compartment body. The utility model not only improves the heat-insulating effect of the compartment, reduces energy consumption, saves transportation costs, and facilitates the reasonable and orderly allocation of storage space inside the compartment, but also prevents water from entering the interior of the compartment, delays rusting of the compartment, and prolongs the service life of the compartment.
