Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Embodiment: As shown in Figures 1 and 2, the aging cabinet includes a cabinet body, a left fan unit 5 that can discharge the air on the front side of the middle part of the cabinet body to the rear side of the left end part in the cabinet body, and a fan unit 5 that can discharge the air on the rear side of the middle part of the cabinet body. The air is discharged to the right fan group 9 on the front side of the right end in the cabinet, the left fan group 5 is positioned at the front side of the left end in the cabinet, and the right fan is positioned at the rear side of the right end in the cabinet; Introduce the deflector 4 on the rear side of the middle part of the cabinet body, and the front side of the right end is provided with the deflector 4 for introducing the air at the right end part into the front side of the middle part of the cabinet body.

When the product rack 2 is pushed into the cabinet body 1, the product rack 2 is provided with a multi-layer product placement board, and the middle part of the product rack 2 is a circuit board 6 connected to the product. The circuit board 6 divides the space in the middle part of the cabinet body 1 into front and rear. The two parts also form the front air channel 7 and the rear air channel 10. The air in the front side of the cabinet body is first discharged from the left fan unit 5 to the rear side of the left end of the cabinet body, and then flows into the cabinet body through the deflector 4. Rear side; the air on the rear side of the middle part of the cabinet is then discharged to the front side of the right end in the cabinet by the right fan unit 9, and returns to the front side of the middle part of the cabinet through the deflector 4, thereby forming a gas circulation. Therefore, there is no need to arrange air ducts in the upper part of the cabinet body 1, and more products can be installed in the cabinet body 1, thereby improving the utilization rate of the cabinet body 1.

Further, the left and right ends of the cabinet 1 are respectively provided with vertical partitions 11, and there are ventilation slots on the partitions 11. The interior space of the cabinet 1 is divided into a left fan area, a product aging area and a right fan area through the partitions 11. area, the left fan unit 5 is located in the left fan area, and the right fan unit 9 is located in the right fan area.

Further, the ventilation slots on the partition 11 are arranged horizontally, and are distributed at the front and rear ends of the partition 11 ;

The ventilation grooves located at the front and rear ends of the partition 11 correspond to the front air duct 7 and the rear air duct 10 respectively. The partition 11 can prevent gas turbulence. When the gas flows in the left and right fan areas, the directional stronger. At the same time, movable blades are arranged on the dividing plate 11, thereby forming a louver that can adjust the air volume, and the air volume can be adjusted according to the situation of the product.

Further, a temperature sensing device (not shown in the figure) is provided inside the cabinet body 1, and a temperature sensing device is provided inside the cabinet body.
