[0037] The embodiments of the present application will be described in detail below with reference to the drawings.

[0038] As shown in the Figure 1 embodiments of the present application provide a cold circulation device, comprising: a box 1, a partition 2, a circulating fan 5, a condensation plate 6, a cold air fan 7, an ultra-low temperature evaporator 8 and a heat preservation layer 9. One side of the box 1 has a box door 11. The partition 2 is installed in the box 1, which divides the box 1 into a circulating chamber 3 and a freezing chamber 4. The partition 2 located at the top of the box 1 is provided with an air inlet channel 21 connecting the circulating chamber 3 and the freezing chamber 4, and the partition 2 located at the bottom of the box 1 is provided with an air outlet channel 22. The circulating fan 5 is installed in the circulating chamber 3, and the air inlet of the circulating fan 5 is arranged towards the air inlet channel 21. The condensation plates 6 are arranged in sequence along the direction of air flow in the circulating chamber 3. The cold air fan 7 is installed on the side wall of the circulating chamber 3, and the air outlet of the cold air fan 7 is arranged towards the air outlet channel 22. The ultra-low temperature evaporator 8 is installed close to the air inlet of the cold air fan 7. The heat preservation layer 9 is arranged on the side wall of the circulating chamber 3 away from the freezing chamber 4.

[0039] In use, the circulating fan 5 sucks the air in the freezing chamber 4 into the circulating chamber 3, and the air enters the circulating chamber 3 for circulation. During the circulation process, the temperature of the air in the circulating chamber 3 will rise, and water mist will be generated during the temperature rising process. Therefore, the condensation plate 6 is arranged in the circulating chamber 3 to perform preliminary condensation. The condensed air is treated by the ultra-low temperature evaporator 8, and then re-entered into the freezing chamber 4 by the cold air fan 7.

[0040] The circulating fan 5 and the cold air fan 7 circulate the air in the freezing chamber 4, so that the temperature in the freezing chamber 4 is more uniform.

[0041] The condensation plate 6 is arranged in the circulating chamber 3 to reduce the humidity in the air, so as to avoid that the humidity in the circulating air is too large.

[0042] The heat insulation layer 9 is arranged on the side wall of the circulating chamber 3 to improve the heat insulation performance of the box 1 and reduce the energy consumption of the freezer. It should be noted that the heat insulation layer 9 is foamed polyurethane, glass wool board, vacuum insulation board or expanded perlite.

[0043] In another embodiment, as shown in Figure 2 , in order to further improve the heat insulation performance of the freezing chamber 4, heat insulation felt 13 is arranged on the outer side wall of the box 1 and the inner side of the box door 11.

[0044] In another embodiment, in order to reduce the influence of materials on temperature, the partition plate 2 is made of the same material as the box 1, and the partition plate 2 is fixed to the box 1 by screws.

[0045] In another embodiment, in order to avoid the normal use of the circulating fan 5 and the cold air fan 7 caused by too low temperature, the bearings of the circulating fan 5 and the cold air fan 7 are ceramic bearings.

[0046] In another embodiment, as shown in Figure 1 and Figure 2 , in order to avoid the accumulation of condensed water on the condensing plate 6, the condensing plate 6 is arranged inclined towards the bottom of the box 1.

[0047] In another embodiment, as shown in Figure 1 and Figure 2 , the cold energy circulating device further comprises a water pan 10 and a drain pipe 110. The water pan 10 is installed in the circulating chamber 3 and located between the condensing plate 6 and the ultra-low temperature evaporator 8. The condensed water on the condensing plate 6 is collected in the water pan 10. One end of the drain pipe 110 communicates with the water pan 10, and the other end is connected to the outside of the box 1. The condensed water in the water pan 10 is led out through the drain pipe 110 to avoid the condensate water from blocking the air outlet channel 22.

[0048] In another embodiment, as shown in Figure 2 , in order to improve the condensation efficiency, a plurality of condensing strips 61 are arranged on the side wall of the condensing plate 6 facing the air inlet channel 21.

[0049] In another embodiment, as shown in Figure 2 , in order to make the air in the freezing chamber 4 more uniform, the air outlet channels 22 are uniformly arranged on the partition plate 2 located at the bottom of the box 1, and the air outlet channels 22 are arranged in a horn shape, and the large end of the diameter is arranged towards the inside of the box 1.

[0050] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments.
