[0057] The utility model is further illustrated below by way of examples, but the utility model is not limited in the following examples.

[0058] The embodiment provides a refrigerator, which comprises a heat dissipation channel 100.

[0059] As shown in Figures 1-3 , the heat dissipation channel 100 comprises an air inlet channel 200, an air outlet channel 300 and a compressor chamber 400, one end of the air inlet channel 200 is communicated with the compressor chamber 400, the other end of the air inlet channel 200 is provided with an air inlet 210, one end of the air outlet channel 300 is communicated with the compressor chamber 400, the other end of the air outlet channel 300 is provided with an air outlet 310, the heat dissipation channel 100 further comprises a partition 500, and the air inlet channel 200 and the air outlet channel 300 are respectively arranged on two sides of the partition 500. The distance from one end of the air inlet 210 close to the partition 500 to the central axis x of the heat dissipation channel 100 is L1, the distance from one end of the air outlet 310 close to the partition 500 to the central axis x of the heat dissipation channel 100 is L2, and L2>L1.

[0060] It should be specifically pointed out that, as shown in Figure 3 , the central axis x refers to the line where the midpoint of the length direction of the heat dissipation channel 100 is located.

[0061] The two ends of the air inlet channel 200 are communicated with the compressor chamber 400 and the air inlet 210 respectively, and the cold air enters the compressor chamber 400 from the air inlet 210 through the air inlet channel 200. The two ends of the air outlet channel 300 are communicated with the compressor chamber 400 and the air outlet 310 respectively, and the hot air of the compressor chamber 400 is discharged from the air outlet 310 through the air outlet channel 300. The partition 500 is arranged between the air inlet channel 200 and the air outlet channel 300, so that the air inlet channel 200 and the air outlet channel 300 can be spaced apart. By making L2>L1, the air outlet 310 is further away from the central axis x of the heat dissipation channel 100 relative to the air inlet 210, so that the air outlet 310 can be away from the air inlet 210, and the hot air flow of the air outlet 310 is prevented from being reabsorbed into the air inlet 210, thereby improving the heat dissipation efficiency.

[0062] The heat dissipation channel 100 also includes a filter element 600, which includes a filter channel 610. One end of the filter channel 610 is connected to the air inlet 210 and the air outlet 310, and the other end is connected to the outside. This ensures that when airflow passes between the heat dissipation channel 100 and the outside, it must first pass through the filter channel 610. Foreign objects from the outside can be blocked by the filter channel 610, preventing them from entering the air inlet channel 200 and the air outlet channel 300 through the air inlet 210 and the air outlet 310. At the same time, it can also filter the airflow blown out of the air outlet 310, preventing foreign objects inside the heat dissipation channel 100 from being blown to the outside.

[0063] The filter element 600 includes a barrier element 620, which is disposed between the air inlet 210 and the air outlet 310. The two ends of the barrier element 620 are respectively connected to the spacer 500 and the filter element 600. The barrier element 620 can separate the part between the air inlet 210 and the air outlet 310 that is connected by the filter element 600. This further prevents hot air from the air outlet 310 from being re-inhaled into the air inlet 210 through the interior of the filter element 600, reducing hot air recirculation and further improving heat dissipation efficiency.

[0064] like Figure 4 As shown, in this embodiment, the barrier 620 includes a first barrier 621, which is disposed at one end of the partition 500 near the air inlet 210. This protects the air inlet 210 at the end of the partition 500 near the air inlet 210, preventing hot air from the outlet 310 from flowing back into the air inlet 210. The barrier 620 also includes a second barrier 622, which is disposed at one end of the partition 500 near the air outlet 310. This blocks the hot air from the outlet 310 at the end of the partition 500 near the air outlet 310, improving the effectiveness of the barrier 620 in blocking hot air and further enhancing heat dissipation efficiency. In other embodiments, only one barrier 620 may be provided in the middle of the partition 500. Those skilled in the art can also choose other suitable numbers and positions of barrier 620.

[0065] In the embodiment, the first barrier 621 extends along the extension direction of the air inlet 210, so as to guide the air inlet direction of the air inlet 210 through the first barrier 621, which is beneficial to guiding the air inlet of the air inlet 210, and the air inlet 210 can be protected more sufficiently, and the hot air flow of the air outlet 310 is prevented from flowing back to the air inlet 210. The second barrier 622 extends along the extension direction of the air outlet 310, so as to guide the air outlet direction of the air outlet 310 through the second barrier 622, which is beneficial to guiding the air outlet of the air outlet 310, and the hot air flow of the air outlet 310 is prevented from flowing to the air inlet 210, and the heat dissipation efficiency is further improved. In other embodiments, the extension direction of the barrier 620 can be selected by those skilled in the art.

[0066] The air inlet 210 and the air outlet 310 are located on the same side of the heat dissipation channel 100, so as to increase the flow path of the air flow, and the air flow is more sufficient, and the heat dissipation effect is improved. At the same time, the air inlet 210 and the air outlet 310 are arranged on the same side, so that the whole structure of the heat dissipation channel 100 is more compact, and the space occupied by the heat dissipation channel 100 is reduced.

[0067] In other embodiments, the positions of the air inlet 210 and the air outlet 310 can be adjusted according to actual needs.

[0068] As shown in Figure 5 and Figure 6 , the air inlet channel 200 includes a first through hole 220, which is arranged at the bottom of the air inlet channel 200 and at one end of the air inlet channel 200 close to the air inlet 210. The first through hole 220 is used to accommodate the first closure 710. The air outlet channel 300 includes a second through hole 320, which is arranged at the bottom of the air outlet channel 300 and at one end of the air outlet channel 300 close to the air outlet 310. The second through hole 320 is used to accommodate the second closure 720, so that the heat dissipation channel 100 can be supported by the first closure 710 and the second closure 720 during transportation, and the first closure 710 and the second closure 720 protrude from the surface of the heat dissipation channel 100, so as to avoid direct contact between the heat dissipation channel 100 and the transportation tool, and the transportation is safer.

[0069] The heat dissipation channel 100 further comprises a first closure 710 and a second closure 720, the first closure 710 is detachably connected to the first through hole 220 and the first closure 710 is matched with the first through hole 220 in shape, and the second closure 720 is detachably connected to the second through hole 320 and the second closure 720 is matched with the second through hole 320 in shape. After the transportation is completed, the first closure 710 can be connected to the first through hole 220 and the first closure 710 is matched with the first through hole 220 in shape, so that the first through hole 220 can be closed by the first closure 710, and the hot air flow of the air outlet channel 300 is prevented from entering the air inlet channel 200 from the first through hole 220. Similarly, the second closure 720 can be connected to the second through hole 320, so that the second through hole 320 can be closed by the second closure 720, and the hot air of the air outlet channel 300 is prevented from diffusing to the air inlet channel 200 through the second through hole 320, further improving the heat dissipation efficiency.

[0070] In the embodiment, the filter channel 610 comprises a grid 611, so that the foreign matters in the outside can be blocked by the grid 611, and the foreign matters are prevented from entering the air inlet channel 200 and the air outlet channel 300. In other embodiments, the filter channel 610 can also comprise other structures to achieve the effect of blocking foreign matters, and the person skilled in the art can select according to the actual needs.
