As shown in fig. 1, fig. 2 and fig. 7, a rapid cooling refrigeration display cabinet comprises a hollow box body 1 and a base 2, the base 2 is arranged below the box body 1, a plurality of layers of shelves 3 are arranged in the box body 1, in the embodiment, the number of the shelves 3 is five layers and is uniformly and vertically distributed, the shelves can be arranged according to the length of the specific box body 1 in actual production, the shelf is not limited to five layers, and more shelves 3 are provided, so that more goods can be placed to meet different requirements of people. In this embodiment, be equipped with the swivel mount 30 that is used for promoting goods forward on goods shelves 3 and be used for driving the motor 31 of swivel mount 30, motor 31 locates the end of goods shelves 3, and when motor 31 rotated, drive swivel mount 30 rotated, and swivel mount 30 will place the goods at goods shelves 3 and promote forward in proper order for goods can push gradually from goods shelves 3 and fall out in the mouth to make the user can take corresponding goods, reach the purpose of automatic shipment. As a modification, the bottom of the shelf 3 is provided with a vent hole 32 to enhance the cooling effect of the goods.

The base 2 is provided with a cooling device 4 for cooling the inside of the box 1, and condensed air 5 produced by the cooling device 4 can cool the goods on the shelf 3, and the flowing direction of the condensed air 5 will be described in further detail below. The air outlet 40 of the cooling device 4 is connected with the rear plate 10 of the box body 1 to guide the condensed air 5 to flow upwards, specifically, the air guide plate 7 is arranged at the air outlet 40 of the cooling device 4, the condensed air 5 blown out of the box body 1 from the air outlet 40 flows upwards along the length direction of the rear plate 10 under the common shielding of the rear plate 10 and the air guide plate 7, and the condensed air 5 has larger mass than ordinary air, so that the condensed air 5 does work by overcoming gravity in the upwards flowing process, sinks after reaching a certain height, and the effect of cooling the goods on the goods shelf 3 from top to bottom is achieved, so that the condensed air 5 can be fully contacted with the goods, and the cooling effect is improved. In addition, the air inlet 41 of the cooling device 4 is communicated with the hollow box body 1, and the box body 1 and the cooling device 4 form a flow channel for the condensed air 5 to continuously circulate in the box body 1, so that the refrigerating time is shortened, and the refrigerating efficiency is improved. In addition, the motor 31 partially overlaps with the air outlet 40, and the heat of the motor 31 can be taken away by the condensed air 5 flowing out from the air outlet 40, so as to play a role in heat dissipation of the motor 31, and in addition, after the condensed air 5 meets the motor 31, the condensed air 5 at the shielding part of the motor 31 can flow into the goods shelf 3 along the motor 31, so that goods in the goods shelf 3 can be uniformly cooled, and the situation that the goods close to the cabinet door cannot be cooled is avoided.

As shown in fig. 1 to 6, the cooling device 4 includes a condenser 42 and an evaporator 43, the evaporator 43 is disposed at the top end of the housing 2, and the condenser 42 is disposed in the housing 2 to separate the condenser 42 and the evaporator 43, so as to avoid the condenser 42 and the evaporator 43 from interfering with each other. The condenser 42 is connected with a compressor 44, and the condenser 42 is connected with the evaporator 43 through a throttling pipeline 45 to form a closed refrigerating system, so that the condensed air 5 can continuously flow into the box body 1, and the continuous refrigerating effect of the condensed air is realized. The evaporator 43 is also provided with a fan 6 for accelerating the flow of the condensed air 5, and the air suction side of the fan 6 is opposite to the air inlet 41, so that the air energy and the condensed air 5 in the box body 1 are continuously and alternately replaced. After the cooling device 4 is powered on, the low-pressure steam of the refrigerant in the cooling device 4 is sucked by the compressor 44 and compressed into high-pressure steam, and then discharged into the condenser 42, the air in the box body 1 continuously circulates and flows to achieve the purpose of reducing the temperature, the air sucked into the box body 1 by the fan 6 flows through the condenser 42 to take away the heat emitted by the refrigerant, so that the high-pressure refrigerant steam is condensed into high-pressure liquid, the high-pressure liquid is sprayed into the evaporator 43 after passing through the throttling pipeline 45 and is evaporated at a corresponding low pressure to absorb the surrounding heat, meanwhile, the air in the box body 1 continuously enters the evaporator 43 by the fan 6 to exchange heat, and the condenser 42 which is cooled after releasing heat is sent into the hollow box body 1. The liquid refrigerant absorbs the heat of the object to be cooled in the evaporator 43 and then is vaporized into low-temperature and low-pressure steam, the low-temperature and low-pressure steam is sucked by the compressor 44 and compressed into high-pressure and high-temperature steam and then is discharged into the condenser 42, heat is released to a cooling medium (water or air) in the condenser to be condensed into high-pressure liquid, the high-pressure liquid is throttled into low-pressure and low-temperature refrigerant through the throttling pipeline 45, and the refrigerant enters the evaporator 43 again to absorb heat and vaporize, so that the purpose of circulating refrigeration is.

As an improvement, as shown in fig. 8 and 9, a movable water pan 8 is disposed at the bottom of the base 2, the water pan 8 is used for receiving the excess water generated by the condenser 42, so as to avoid environmental pollution, and a slide rail 9 adapted to the movement of the water pan 8 is disposed at the bottom of the base 2, so as to facilitate the water in the water pan 8 to be poured.

The compressor 44 is a power of a refrigeration cycle, is driven by a motor to rotate continuously, and not only extracts vapor in the evaporator in time to maintain low temperature and low pressure, but also increases the pressure and temperature of the refrigerant vapor through compression, creating a condition for transferring the heat of the refrigerant vapor to an external environment medium, i.e., compressing the low temperature and low pressure refrigerant vapor to a high temperature and high pressure state, so that air or water at normal temperature can be used as a cooling medium to condense the refrigerant vapor.

The condenser 42 is a heat exchange device that uses an ambient cooling medium (air or water) to remove heat from the high temperature and high pressure refrigerant vapor from the compressor 44, thereby cooling or condensing the high temperature and high pressure refrigerant vapor into a high pressure and normal temperature refrigerant liquid.

The evaporator 43 is also a heat exchange device, and the throttled low-temperature and low-pressure refrigerant liquid is evaporated (boiled) in the evaporator to become steam, so that the heat of the cooled substance is absorbed, the temperature of the substance is reduced, the purpose of freezing and refrigerating food is achieved, the ambient air can be cooled, and the effects of cooling and dehumidifying the box body 1 are also achieved. The lower the evaporation temperature of the refrigerant in the evaporator 43, the lower the temperature of the object to be cooled.

In addition, it should be further explained that the refrigerant liquid at high pressure and normal temperature is directly sent to the low temperature evaporator 43, and the pressure of the refrigerant liquid is reduced according to the principle that the saturation pressure corresponds to the saturation temperature, so as to reduce the temperature of the refrigerant liquid. The refrigerant liquid with high pressure and normal temperature is depressurized through the throttling pipeline 45 to obtain a low-temperature and low-pressure refrigerant, and then the low-temperature and low-pressure refrigerant is sent to the evaporator 43 through the throttling pipeline 45 to be evaporated in a heat absorption mode. In the prior art, a capillary tube is commonly used as a throttling pipe.
