[0028] The utility model will be further explained in detail in connection with the drawings.

[0029] The working principle of the utility model is as Figures 1-5 shown, a kind of fruit and vegetable fresh-keeping cold storage air exchange device, comprising: equipment box 1, the middle part of the inner wall of equipment box 1 is fixedly connected with partition 2, the inner cavity of equipment box 1 is divided into two different areas by partition 2, the upper portion of partition 2 is called air outlet cavity, while the lower portion of partition 2 is called air inlet cavity;

[0030] air inlet pipe two 7 and air outlet pipe one 5 are respectively connected in the lower part of the front and rear end of equipment box 1, and the rear end of air inlet pipe two 7 is fixedly connected with centrifugal fan two 9, when centrifugal fan two 9 operates, the air of outside is sucked into the air inlet cavity of equipment box 1;

[0031] At the same time, air inlet pipe one 4 is connected in the upper part of the rear end of equipment box 1, and air outlet pipe two 6 is connected in the front part of the top end of equipment box 1, wherein the front end of air inlet pipe one 4 is fixedly connected with centrifugal fan one 8, and the bottom end of air outlet pipe two 6 is fixedly connected with gas valve 10 for controlling gas in and out, when centrifugal fan one 8 operates, the air in cold store is sucked into the air outlet cavity of equipment box 1, wherein gas valve 10 is communicated with the gas pump of outside, and can automatically operate according to requirement;

[0032] Here, it is to be explained that the inner wall of air outlet pipe one 5, air outlet pipe two 6, air inlet pipe one 4 and air inlet pipe two 7 is fixedly connected with filter plate for preventing dust and impurities from entering equipment box 1.

[0033] Since, in air outlet cavity, it is the gas extracted from cold store, and in air inlet cavity, it is the gas sucked from outside, so the temperature in air outlet cavity will be lower than the temperature in air inlet cavity;

[0034] The heat conduction device 3 is arranged on the partition plate 2 uniformly, and the gas in the air inlet cavity of the equipment box 1 is cooled in advance through the heat conduction device 3.

[0035] Meanwhile, a plurality of spoiler plates 11 are arranged in the air inlet cavity, and it is to be explained that the spoiler plates 11 are arranged in a wave shape, the upper spoiler plates 11 are fixedly connected to the partition plate 2, and the lower spoiler plates 11 are fixedly connected to the bottom wall of the equipment box 1, the spoiler plates 11 interfere with the flow of the gas, thereby effectively prolonging the residence time of the gas in the air inlet cavity, which not only increases the contact time of the gas with the elements in the heat conduction device 3, but also enables the gas in the air inlet cavity to be continuously cooled;

[0036] Finally, a control chip is fixedly connected to the top wall of the equipment box 1, and an infrared temperature detector for detecting the gas near the air outlet pipe 5 is fixedly connected to the rear end of the bottom of the partition plate 2, wherein the control chip is electrically connected with the infrared temperature detector, the centrifugal fan 8, the centrifugal fan 9 and the gas valve 10, and the control chip can control the operation and stop of the above-mentioned equipment, and it is to be explained that the principle of the control chip controlling the equipment is not the focus of the present application, and the control chip itself is an existing product that can be purchased in the market, and the specific operation principle will not be described here.

[0037] The above-mentioned various structures jointly constitute the general appearance structure of the air exchange device of the fruit and vegetable fresh-keeping cold storage.

[0038] In embodiment 1, the heat conduction device 3 comprises a heat conduction shaft 301 fixedly connected to the partition plate 2, and the heat conduction shaft 301 is made of a metal material with good heat conduction;

[0039] The upper part and the lower part of the heat conduction shaft 301 are fixedly connected with a plurality of heat plates 302 and a plurality of heat plates 303, respectively, wherein the plurality of heat plates 302 are located above the partition plate 2, and the heat plates 303 are located below the partition plate 2, and it is to be explained that the plurality of heat plates 302 are arranged in a cross shape with uniform angle intervals to increase the contact area with the gas;

[0040] Meanwhile, a heat conduction cavity 304 is formed in the middle part of the heat conduction shaft 301, and a plurality of air holes 305 are formed in the outer wall of the heat conduction shaft 301 above the partition plate 2 and are in communication with the heat conduction cavity 304;

[0041] At this point, the continuous flow of gas in the heat conduction cavity 304 and the air hole 305 effectively takes away the heat on the heat conduction shaft 301. At the same time, the synergistic effect of the heat conduction shaft 301, the heat spreader one 302 and the heat spreader two 303 significantly improves the efficiency of heat transfer through the dual mechanisms of gas convection and solid conduction. This design ensures the effective dispersion of heat, thereby optimizing the heat management performance of the entire air exchange device.

[0042] In summary, when using the device, first firmly install the equipment box 1 on the inner wall of the cold storage. The air inlet pipe one 4 and the air outlet pipe one 5 are located inside the cold storage, which constitutes the main channel for gas exchange in the cold storage. At the same time, the air outlet pipe two 6 and the air inlet pipe two 7 are located outside the cold storage, responsible for gas exchange with the outside environment.

[0043] The process of gas exchange is first to extract the air in the cold storage, and then to introduce fresh outside air. The specific operation is as follows:

[0044] Start the centrifugal fan one 8 to suck the air in the cold storage into the air outlet cavity. Because the temperature of these gases is low, it will gradually lower the temperature of the heat spreader one 302. At the same time, these cold air is blown into the heat conduction cavity 304, and through the heat transfer effect, the temperature of the heat spreader two 303 will also be lowered. Then, open the air valve 10 to make the gas flow to the outside through the air outlet pipe two 6.

[0045] When the air in the cold storage is extracted to a certain extent, the centrifugal fan one 8 and the air valve 10 are closed, and then the centrifugal fan two 9 is started to suck the outside air into the air inlet cavity. Because the temperature of the heat spreader two 303 is lower than that of the newly sucked air, the temperature of the air will be further lowered when it contacts the heat spreader two 303. In this process, the role of the spoiler 11 increases the contact time of the air with the heat spreader two 303, so that the temperature of the sucked air is further lowered. Finally, these cooled air is discharged into the cold storage through the air outlet pipe one 5.

[0046] Compared with the prior art, the fresh air can be pre-cooled, so that in the subsequent refrigeration process of the cold storage, more energy consumption is not needed, thereby achieving the goal of energy saving and emission reduction, improving the energy efficiency of the cold storage and the efficiency of fruit and vegetable preservation.

[0047] Finally, it should be pointed out that the utility model has made airtight treatment between the key parts of the parts, which will not cause gas leakage and can ensure the normal operation of the equipment.

[0048] The above describes the present application and its embodiments, which are not restrictive, and the drawings only show one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the spirit of the present application, without creative design, similar structure and embodiments of the technical solution, which should belong to the protection scope of the present application.

[0049] In addition, the electrical components appearing in the text are all connected with the main controller and 220V mains electricity, and the main controller can be a computer or other known device that can be controlled, and the detailed description of the known functions and known components is omitted in the specific embodiment of the present application. In order to ensure the compatibility of the device, the operation means adopted is consistent with the market instrument parameters.
