[0002] Cold chain refers to the process of keeping products at a specified low temperature during production, storage, transportation, and sales through specific refrigeration facilities and technologies to ensure their quality. Because the cold air distribution inside cold chain compartments is uneven and products are prone to odors, ventilation is required.

[0003] The publication number CN222820162U discloses a ventilated cold chain transport compartment, which includes a compartment body, a refrigeration unit, a heat exchanger, a circulation pipe and a blower. The refrigeration unit and the heat exchanger are circulated together, and a refrigerant is introduced to remove heat.

[0004] The aforementioned cold chain transport compartments can control the airflow at each point, but when the internal cold air is easily leaked out during ventilation, it is inconvenient for the internal air to circulate. Furthermore, the odors and moisture that the products are prone to generate are not easily filtered and absorbed. Utility Model Content

Slots 7 are provided on both sides of the fixed box 1. The two air ducts 5 are respectively installed on both sides of the fixed box 1. Two identical fixed plates 2 are fixedly installed at the outer end of the air duct 5. A through groove 8 is provided at the inner end of the air duct 5. An air inlet groove 9 is provided at the bottom of the air duct 5 near the outer end.

[0020] The fixed box 1 and the two air ducts 5 are interconnected. The fixed box 1 and the air ducts 5 are both fixed to the top of the cold chain compartment by the fixing plate 2. The two air ducts 5 are used to transport the air inside the cold chain to the fixed box 1, and then blow it out by the fan 6 for circulation.

[0021] The inner end of the air duct 5 is inserted into the slot 7. The two air ducts 5 are symmetrical to each other. The inner end of the air duct 5 is inserted into the slot 7, and the outer end of the air duct 5 is installed inside the cold chain compartment near the top through the fixing plate 2.

[0022] The air inlet slot 9 and the fan 6 are oriented downwards. Air inside the cold chain compartment enters through the air inlet slot 9 and is blown out by the fan 6.

[0023] Specifically, the air inside the cold chain compartment enters the air duct 5 through two air inlets 9 and then enters the fixed box 1 and is blown out by the fan 6, so that the cold air inside the cold chain compartment is evenly distributed.

[0024] Example 2 See Figure 3 Furthermore, based on Embodiment 1, the filter assembly 4 includes a filter box 10, which is installed in the through groove 8. Both sides of the filter box 10 are equipped with grid plates 11. The filter box 10 has an internal receiving groove 12, which contains activated carbon packs 13 and two moisture-absorbing cottons 14.

[0025] The air duct 5 passes through the grid plate 11 and communicates with the receiving groove 12. The filter box 10 is located in the through groove 8 and is matched with it. The filter box 10 is installed in the receiving groove 12, and the air flows through the grid plate 11.

The outer end of the air guide pipe 5 is fixed to the top of the cold chain compartment with the same two fixing plates 2 and bolts. By starting the fan 6, the air inside the cold chain compartment enters the air guide pipe 5 through the two air inlet slots 9 and enters the fixing box 1. It is then blown out by the fan 6, so that the cold air inside the cold chain compartment is evenly distributed. During filtration, activated carbon packs 13 and two absorbent cottons 14 are installed inside the filter box 10, and the filter box 10 is installed inside the receiving slot 12. Air flows through the grille 11, and the activated carbon packs 13 absorb odors from the air.
