As shown in fig. 1 to 5, the present invention provides a refrigeration apparatus including: cabinet 1 and refrigeration circuit. Wherein, cabinet 1 includes shell 11 and inner bag 12. The refrigeration circuit includes a compressor (not shown), a condenser (not shown), a throttling device (not shown) and an evaporator 2 connected together. In the actual operation process of the refrigerating device, the refrigerant in the refrigerating circuit circularly flows under the action of the compressor and is refrigerated by the evaporator 2. The cold generated by the evaporator 2 is transferred to the inside of the inner container 12 to realize the storage in the refrigerating inner container 12.

In the first embodiment, for more accurate temperature control, the temperature distribution in the liner 12 is more uniform. The cabinet body 1 further comprises a lining 13, wherein the lining 13 is arranged in the shell 11, an insulation layer is formed between the lining 13 and the shell 11, the liner 12 is arranged in the lining 13, and an evaporation cavity is formed between the back of the liner 12 and the back of the lining 13; the evaporator is positioned in the evaporation cavity;

the refrigeration device further comprises an evaporation fan 3, wherein the evaporation fan 3 is positioned in the evaporation cavity and used for driving air flow subjected to heat exchange through the evaporator to the surface of the liner 12.

In the actual use process, the cold energy generated by the evaporator refrigerates the air in the evaporation cavity, and under the action of the evaporation fan 3, the air in the evaporation cavity can be driven to circularly flow. In this way, the cooled air can flow to the outer surface of the liner 12, so as to realize the air cooling treatment of the liner 12 outside the liner 12. The cold air flows outside the inner container 12 to cool the inner container 12 more uniformly, so that the overall cooling temperature of the inner container 12 is distributed uniformly. And to the storing cavity that inner bag 12 inside formed, because the temperature distribution of inner bag 12 is even, through the inside refrigeration mode that realizes directly cooling of inner bag 12 to make the temperature distribution in the storing cavity more even.

In some embodiments, in order to make the air supply amount uniform to more uniformly cool the liner 12, a first air circulation area is formed between the sidewall of the liner 12 and the corresponding sidewall of the liner 13. Specifically, the cold air after heat exchange treatment by the evaporator is circularly conveyed to the area between the side wall of the liner 12 and the corresponding side wall of the liner 13 under the action of the evaporating fan 3, so that the cold air can be effectively conveyed to the side wall of the liner 12 to refrigerate the side wall of the liner 12. Thus, both side walls of the liner 12 can be uniformly cooled.

In another embodiment, a second wind circulation area is formed between the top of the liner 12 and the top of the liner 13. The air after heat exchange by the evaporator flows into the first air circulation area to exchange heat with the side wall of the inner container 12, then the cold air continues to flow upwards under the action of the evaporating fan 3, so that the cold air exchanges heat with the top of the inner container 12, and finally, the upper part and the two side parts of the inner container 12 can obtain the cold air to refrigerate.

Meanwhile, the air after heat exchange flows along the back of the liner 12 and exchanges heat with the evaporator, and the air can refrigerate the back of the liner 12 at the same time in the process of exchanging heat along the evaporator, so that the back of the liner 12 can also be refrigerated.

Specifically, the air after heat exchange with the liner 12 enters the first heat exchange air channel and the second heat exchange air channel respectively, and the air can fully contact with the two sides of the evaporator for heat exchange, so that the heat exchange efficiency is improved. Meanwhile, as the evaporator adopts the plate-shaped structure, the occupied space of the evaporator in the evaporation cavity is smaller, and meanwhile, the wind resistance of the plate-shaped structure of the evaporator is smaller, so that smooth and efficient circulating flow of air between the liner 12 and the liner 13 can be better met.

In the preferred embodiment, the evaporation fan 3 is located below the evaporator, and the cold air formed after heat exchange of the evaporator falls to the evaporation fan 3 by using the principle of cold air sinking, and then the cold air is blown to the liner 12 by using the evaporation fan 3. In this way, the outer wall of the liner 12 can obtain enough cool air for refrigeration, and the cool air at the bottom flows upwards along the side wall of the liner 12 under the action of the evaporating fan 3. And the principle of hot gas rising is matched, so that the cold air can more uniformly cover the side wall of the inner container 12 to exchange heat.

Specifically, by disposing the corresponding sub-evaporation fans 31 on the two sides of the inner container 12, the sub-evaporation fans 31 on the corresponding side can supply air to the side wall of the inner container 12 facing the corresponding side corresponding to the cool air, so that the cool air is uniformly delivered and distributed on the two sides of the inner container 12.

In some embodiments, in order to enable the air flow to flow along the side wall of the inner container 12 and more comprehensively and uniformly cool the corresponding side wall of the inner container 12, a plurality of air guide division bars 14 are respectively arranged on two side walls of the inner container 12, and the air guide division bars 14 are transversely arranged and clamped between the inner container 12 and the liner 13. Specifically, in the process of driving the cool air to blow towards the side wall of the liner 12 through the evaporation fan 3, the cool air is guided and transmitted through the air guide division bars 14, so that the cool air can flow along the side wall of the liner 12 and comprehensively cover the side wall of the liner 12 to perform uniform refrigeration and heat exchange.

Preferably, the two vertically adjacent wind guide parting strips 14 are arranged in a staggered manner, and an overlapping area is formed by the projection of the vertically adjacent wind guide parting strips 14. Thus, a diversion flow passage can be formed on the side wall of the inner container 12, and cold air flows along the diversion flow passage limited by the air guide division bars 14 on the side wall of the inner container 12, and finally, the cold air flows along the side wall of the inner container 12 to the top of the inner container 12.
