Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, specifically to a cold air self-circulating cooling device. Background Technology

[0002] Preservation technology for dairy products is a crucial factor in determining their taste. This requires cooling from 10°C to 4°C. Currently, most technologies cool entire stacks of dairy products from 10°C to 4°C by placing them statically in a cold storage room. However, due to the unique stacking method, this leads to uneven cooling; the outer layers cool faster than the inner layers, resulting in poor cooling efficiency. Furthermore, this static heat exchange method results in excessively long cooling times—approximately 5 hours or more—from 10°C to 4°C. This is not only inefficient but also detrimental to the taste of the dairy products, negating the purpose of preservation. Utility Model Content

[0003] In order to overcome the technical problems of low efficiency and uneven heat exchange in existing cooling devices, the present invention provides a cold air self-circulating cooling device.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objective is as follows: a cold air self-circulating cooling device, including a cooling box, an evaporator is provided inside the cooling box, the evaporator is fixed to the top of the cooling box, a fan is provided on one side of the evaporator, the air outlet of the evaporator is connected to the air inlet of the fan, a storage area is provided below the evaporator, a partition is provided between the evaporator and the storage area, one side of the storage area is connected to the air outlet of the fan, the other side of the storage area is connected to the air inlet of the evaporator, and openings are provided on the front and rear side walls of the cooling box corresponding to the storage area.

[0005] Preferably, a conveyor belt is provided at the bottom of the storage area, and the conveyor belt extends from the openings on the front and rear side walls of the cooling box to the outside of the cooling box.

[0006] Preferably, a foot pedal is provided below the fan, the foot pedal has ventilation holes, and a mounting base is provided on the foot pedal, and the fan is fixed on the mounting base.

[0007] Preferably, a sealing soft curtain parallel to the front sidewall of the cooling box is provided at the edge of the opening.

[0008] Compared with the prior art, the advantages of this utility model are that by setting up a fan and an evaporator, and setting up a storage area below the evaporator, the cold air can be circulated on its own. Through self-circulation, the cold air blown towards the storage area is always cold air, which can make the entire stack of dairy products undergo heat exchange evenly and avoid the situation of the outside being cold and the inside being hot. At the same time, a sealing soft curtain is set at the edge of the opening. The sealing soft curtain and the dairy products form a near-sealed environment, which can improve the heat exchange efficiency inside the device and reduce the leakage of cold air.

[0012] A specific embodiment of the cold air self-circulating cooling device of this utility model is as follows: Figure 1 As shown, the device includes a cooling box 1, an evaporator 2 inside the cooling box 1, the evaporator 2 being fixed to the top inside the cooling box 1, a fan 3 on the right side of the evaporator 2, the air outlet of the evaporator 2 being connected to the air inlet of the fan 3, a storage area 4 below the evaporator 2, a conveyor belt 8 at the bottom of the storage area 4, openings on the front and rear side walls of the cooling box 1 corresponding to the storage area 4, the conveyor belt 8 extending from the openings on the front and rear side walls of the cooling box 1 to the outside of the cooling box 1, a partition plate 5 between the evaporator 2 and the storage area 4, the evaporator 2 being fixed to the partition plate 5, the left side of the storage area 4 being connected to the air outlet of the fan 3, and the right side of the storage area 4 being connected to the air inlet of the evaporator 2, a sealing soft curtain 7 parallel to the front side wall of the cooling box 1 at the edge of the opening, a foot pedal 6 below the fan 3, ventilation holes on the foot pedal 6, a mounting base on the foot pedal 6, and the fan 3 being fixed to the mounting base.

[0013] Working process: A stack of dairy products is placed on conveyor belt 8. The stack consists of multiple boxes containing bottled dairy products. Each box has a through-hole, and the through-hole is placed perpendicular to the conveyor belt 8. Conveyor belt 8 transports the stack of dairy products to storage area 4. The sealing curtain 7 at the opening forms a nearly sealed channel with the stack of dairy products. Evaporator 2 and fan 3 are turned on. Fan 3 draws room temperature air from the right side of storage area 4 into evaporator 2, where it is cooled. Fan 3 then blows the cooled air out. Air passes through the vent on the foot pedal 6 and is blown in from the left side of the storage area 4. The cold air enters the storage area 4 and then enters through the vent on the stack of dairy product boxes. It comes into contact with the dairy products, carries away the heat, and is blown out from the right side of the storage area 4. It is then drawn into the evaporator 2 by the fan 3 to cool the room temperature air again. The air is then blown out from the left side of the storage area 4, thus circulating the cold air. After the dairy products are cooled, the conveyor belt 8 transports the cooled dairy products out of the storage area 4. When the machine is being repaired, workers can stand on the foot pedal 6 to work.
