AI Technical Summary

Technical Problem

The energy consumption of existing driverless refrigerated vehicles is relatively high, especially the power loss of refrigeration equipment increases with changes in climate and heat load, resulting in the problem of power shortage.

Method used

An unmanned refrigerated truck was designed. By directly setting the evaporator refrigeration tube in the refrigeration box, combining thermally conductive silicone and polyurethane foam insulation, the use of evaporator fins and fan is reduced, and the use of S-shaped and spirals is adopted. The coiled evaporator refrigeration tube structure, the insulation cavity between the outer shell and the inner shell is filled with polyurethane foam, and a partition is provided in the protective cover to isolate the refrigeration assembly and the refrigeration box, reducing energy consumption and noise.

Benefits of technology

It effectively reduces the energy consumption of refrigerated trucks, improves refrigeration efficiency and stability, and reduces the impact of noise on customers and extends the battery life time.

Abstract

The utility model provides an unmanned refrigerator car, and belongs to the technical field of unmanned cold-chain logistics. The problem that an existing unmanned retail refrigerator car is high in energy consumption is solved. The unmanned refrigerator car comprises a car body, a refrigerating box and a refrigerating assembly, the refrigerating box and the refrigerating assembly are arranged on the car body, a refrigerating chamber is arranged in the refrigerating box, an opening of the refrigerating chamber is covered with a box cover, and the refrigerating assembly comprises a compressor, a condenser, an expansion valve and an evaporator refrigerating pipe. The evaporator refrigerating pipe comprises a first coil pipe wound around the side portion of the refrigerating chamber and a second coil pipe wound around the bottom of the refrigerating chamber, and the first coil pipe is communicated with the second coil pipe. The refrigerating pipe of the evaporator is directly arranged in the refrigerating box, and an evaporator fin and an evaporation fan do not need to be used for assisting heat transfer, so that the refrigerating capacity of the refrigerating box can be ensured, and the operation energy consumption can be reduced.
