Abstract

The invention provides a vehicle-mounted multi-temperature-area refrigerator which comprises a Sterling motor. The Sterling motor comprises a motor body, a cold end and a hot end. A base and a draughtfan are further included. The base is provided with an air inlet and an air outlet. The base is provided with a heat insulation structure made of a heat insulation material. The heat insulation structure comprises a heat insulation bottom plate and a heat insulation cover. One part of the motor body of the Sterling motor is arranged on the heat insulation bottom plate, and the heat insulation bottom plate is arranged on the base. A heat exchange cavity is formed by the heat insulation bottom plate and the heat insulation cover in a cooperative manner. The cold end is arranged in the heat exchange cavity, and a first air passing opening and a second air passing opening are formed in the heat insulation bottom plate so that the heat exchange cavity can communicate with the air inlet and theair outlet. Due to the heat insulation structure, the motor body can be completely isolated from the hot end and the cold end, in addition, air sequentially passes through an air inlet cavity, the first air passing opening, the heat exchange cavity, the second air passing opening and an air outlet cavity from the air inlet to be discharged from the air outlet, and it is ensured that air cannot generate surplus heat exchange with heat of the motor body and the hot end.

Description

technical field [0001] The invention relates to the technical field of refrigeration and heat preservation, in particular to a vehicle-mounted multi-temperature zone refrigerator. Background technique [0002] There are mainly two kinds of car refrigerators on the market, one is semiconductor car refrigerator, its principle is to rely on electronic chips for cooling, and use P-N junctions composed of special semiconductor materials to form thermocouple pairs and produce Peltier effect, that is, through direct current refrigeration. A new refrigeration method. The refrigeration temperature ranges from 5 to 65 degrees. The advantage of this type of refrigerator is that it can both cool and heat, and is environmentally friendly, pollution-free, small in size, low in cost, free from vibration and noise during operation, and has a long service life. The disadvantage is that the cooling efficiency is not high, the cooling temperature is affected by the ambient temperature, the co...
