Technical Field

The utility model relates to a cold chain transportation technical field especially relates to a refrigerator car cold wind channel.

Background

The refrigerator car is used as an intermediate link of a cold chain, generally consists of a refrigerating unit and a heat insulation carriage, has the functions of refrigeration and heat preservation, and is an important vehicle for transporting perishable foods on land. The refrigerating system of the current refrigerator car mainly comprises an evaporator and an externally-hung condensing unit, wherein the evaporator is placed at the front part of a refrigerator carriage, and the distance between the evaporator and the refrigerating unit is shortened to the maximum extent so as to facilitate the design of a refrigeration circulating pipeline. However, when the goods are loaded in the carriage, the goods at the front end are close to the air supply opening compared with the goods at the rear part of the carriage, so that the air flow velocity is high, the temperature is low, and the whole goods are in a front-rear temperature uneven state. In addition, the compact cargo stacks and wall friction in the car create flow resistance to the airflow, resulting in poor ventilation at the rear of the car and airflow stagnation areas. In order to avoid the phenomenon, the existing air duct has two modes of a surface-mounted soft cloth air duct and a concealed air duct;

the soft cloth air duct is easy to damage, unsmooth in ventilation and uneven in cold air distribution, the concealed air duct occupies a top plate space, the heat insulation performance and the top bearing capacity are affected, and the cold air duct for the refrigerator car is provided to avoid the problem that cold air in the refrigerator car has poor circulation.
