The invention provides a controllable uniform-temperature thermal insulation air curtain device in a refrigerator compartment and a control method of the controllable uniform-temperature thermal insulation air curtain device. The traditional thermal insulation air curtain of a refrigerator car is improved, and the unsynchronized rotation of fans along with a door of the refrigerator car is realized through a mechanical transmission mechanism of a door-door connection shafts-bull wheels-racks-pinion wheels-fan covers. When the door is opened at a relatively small angle, the fans are maintained to blow oppositely to form an air curtain, and cold and hot environments are effectively isolated; when the door is closed completely, the densely-distributed fans on two sides blow intermittently. The start and stop are controlled by the highest temperature in the compartment, the wind directions are adjusted by electrical control circuits through shading shutter-like blades in the fan covers, the flowing direction of cold air blown out from the upper end of the refrigerator car is changed, and the temperature inside the refrigerator car is distributed more uniformly. The invention provides the device for the refrigerator car, and the control method of the device; the device has a simple structure, and is low in energy consumption and multi-functional.
