The invention discloses a vehicle-mounted quick-cooling beverage refrigerator and a refrigerating method of the vehicle-mounted quick-cooling beverage refrigerator. The vehicle-mounted quick-cooling beverage refrigerator comprises a shell, a refrigerating chamber, an evaporator assembly, a condenser and a compressor. The evaporator assembly comprises a first evaporator arranged on the side wall of the refrigerating chamber and a second evaporator arranged on the bottom side of the refrigerating chamber. The first evaporator comprises an inlet end, a pre-cooling channel, a supercooling liquid storage channel and an outlet end, and a supercooling liquid storage cavity capable of storing liquid refrigerants is formed in the bottom side of the supercooling liquid storage channel. In this way, the liquid refrigerant is stored through the supercooling liquid storage cavity, compared with an evaporator without a supercooling liquid storage cavity, the quantity of the gaseous refrigerant circulating in the refrigerating system is smaller, the pressure in the first evaporator is lower, and the boiling point of the liquid refrigerant is lower. In this way, when the beverage is cooled, in the process that the refrigerant in the supercooling liquid storage cavity is changed into the gas state from the liquid state to conduct heat exchange, the heat absorption speed is higher, the heat absorption capacity is larger, and the refrigeration efficiency is higher.
本发明公开了一种车载速冷饮料冰箱及该车载速冷饮料冰箱的制冷方法,包括壳体、冷藏室、蒸发器组件、冷凝器和压缩机;该蒸发器组件包括设置于冷藏室侧壁的第一蒸发器,以及设置于冷藏室底侧的第二蒸发器;并且第一蒸发器包括有进口端、预冷通道、过冷储液通道和出口端,该过冷储液通道底侧设有可储存液态冷媒的过冷储液腔。这样通过过冷储液腔来对液态冷媒进行存储,其和无过冷储液腔的蒸发器相比,位于制冷系统内进行循环的气态冷媒量会更少,使第一蒸发器内的压力更低,其液体冷媒的沸点会更低。这样将饮料进行冷却时,位于过冷储液腔内的冷媒由液态变成气态来进行热交换这一过程中,其吸热速度会更快,以及吸热量会更大,制冷效率更高。
