Technical Field

[0001] This utility model relates to the field of refrigerated transportation technology, and in particular to a broken bridge structure for a high-mobility refrigerated and insulated vehicle. Background Technology

[0002] Thermal break structure is one of the key factors in the insulation performance of refrigerated trucks. A well-designed thermal break can effectively prevent heat transfer, thereby improving the insulation effect of refrigerated trucks and reducing energy consumption. At the same time, a well-designed thermal break can also reduce the workload of the refrigeration unit, extend its service life, reduce maintenance costs, and improve the overall performance and safety of refrigerated trucks.

[0003] Therefore, a reasonable structural design for installing thermal break bridges in refrigerated trucks is crucial. Choosing appropriate materials, structures, and parameters can improve the insulation performance of refrigerated trucks, increase work efficiency, and reduce costs.

[0004] Currently, the interior of the compartment of high-mobility refrigerated and insulated trucks, and the structure at the broken bridge section of high-mobility refrigerated and insulated trucks, use integral aluminum profiles, which have the following disadvantages: 1) short refrigeration and insulation time; 2) poor heat insulation effect; 3) complex structure, making it difficult to retrofit and install in existing refrigerated vehicles.

[0005] This utility model provides a thermal break structure for a high-mobility refrigerated and insulated vehicle, which effectively solves these problems and provides a thermal break structure with good heat insulation effect, long heat preservation time, simple structure and easy modification and upgrading.
