[0069] Preferably, the condenser 5 is gradually inclined toward the compressor 3 from the end far away from the compressor 3 to the end close to the compressor 3, which is not only conducive to the flow of wind from the condenser 5 to the wind tube 4, but also can increase the area and efficiency of cold air passing through the compressor 3, thereby dissipating the heat of the compressor 3.

[0070] Specifically in the present embodiment, the condenser 5 gradually tilts backward from an end away from the compressor 3 to an end close to the compressor 3 .

[0074] See also Figures 6 to 9 The refrigeration device 100 further includes an evaporation dish 15 , which is located above the bottom plate 14 , and the condensing fan assembly 10 is located above the evaporation dish 15 .

[0075] Specifically, in this embodiment, the hook portion 45 of the wind tube 4 is provided at the bottom of the wind tube 4 and extends downward from the wind tube 4, and the evaporating dish 15 is provided with a snap-in groove 151 matched with the hook portion 45, and the hook portion 45 is snapped into the snap-in groove 151, so that the wind tube 4 and the evaporating dish 15 are fixedly connected.

[0076] Further, in this embodiment, the second volute 63 is provided with two lugs 632, and the evaporating dish 15 is provided with an assembly hole 152. One of the lugs 632 of the second volute 63 is provided at the lower end of the second volute 63, and the lug 632 extends downward and is fixedly assembled with the assembly hole 152 of the evaporating dish 15 through a fastener, so as to fix the centrifugal fan 6 with the evaporating dish 15. The fastener may be a screw or a rivet.

[0077] By assembling the hook portion 45 with the engaging groove 151 and the lug 632 with the assembling hole 152 , not only can the condensing fan assembly 10 and the evaporating dish 15 be fixedly assembled, but also the assembly strength between the air cylinder 4 and the centrifugal fan 6 is improved.

[0078] Specifically, the assembly hole 152 on the evaporating dish 15 is provided on the rear side wall of the evaporating dish 15 .

[0079] Furthermore, another lug 632 of the second volute 63 is arranged on the side of the second volute 63 , and the lug 632 extends to the side of the second volute 63 and is fixedly assembled with the chamber wall of the compressor chamber 2 through fasteners to improve the assembly firmness of the centrifugal fan 6 .

[0080] In this embodiment, the air outlet of the centrifugal fan 6 opens upward. In other embodiments, the direction of the air outlet of the centrifugal fan 6 can also be set according to actual needs, and can be set to open downward, or toward other directions, such as toward the compressor 3.

[0081] A wedge-shaped air guide groove 11 is formed on the rear wall 13 of the box body 1. The wedge-shaped air guide groove 11 is located above the compressor chamber 2. The air outlet of the centrifugal fan 6 is connected to the wedge-shaped air guide groove 11. The compressor chamber 2 is connected to the external space behind the box body 1 through the wedge-shaped air guide groove 11.

[0082] Furthermore, the volute air duct is formed with an air guide portion 66 extending obliquely from bottom to top and backward, and the air outlet of the centrifugal fan 6 is formed at the upper end of the air guide portion 66, so that the air flow blown out from the air outlet of the centrifugal fan 6 has a certain slope to reduce wind resistance. Preferably, the angle between the air guide portion 66 and the up-down direction is 60°.

[0083] Furthermore, the press chamber 2 further includes a pair of side chamber walls arranged opposite to each other, and the air guide portion 66 is inclined from bottom to top away from the side chamber wall adjacent thereto.

[0084] In this embodiment, a pair of side walls of the compressor chamber 2 includes a left chamber wall 21 and a right chamber wall 22 that are arranged opposite to each other. If the centrifugal fan 6 is arranged adjacent to the left chamber wall 21, an air guide 66 is arranged to be away from the left chamber wall 21 from bottom to top, that is, inclined to the right. In this way, the heat dissipation efficiency can be improved, so that the hot air discharged from the air outlet of the centrifugal fan 6 to the rear of the box body 1 through the air guide 66 is discharged upward in a direction away from the left chamber wall 21, thereby avoiding the problem that the heat dissipation of the refrigeration device 100 is blocked by foreign objects and leads to poor heat dissipation efficiency. In other embodiments, if the centrifugal fan 6 is arranged adjacent to the right chamber wall 22, the air guide 66 is arranged to be inclined to the left from bottom to top.

[0086] See also Figure 6 Furthermore, the refrigeration device 100 also includes a wind shield 12 arranged on the rear wall 13 of the box body 1 to separate the air inlet path and the air outlet path of the compressor compartment 2.

[0087] In this embodiment, the wind shield 12 is horizontally placed between the wedge-shaped air guide groove 11 and the built-in space of the compressor chamber 2, so as to prevent the hot air blown out by the centrifugal fan 6 from flowing back downward into the compressor chamber 2 and reducing the heat dissipation efficiency.

[0088] Furthermore, the compressor compartment 2 defines a built-in space open to the rear, that is, the design of the back plate of the compressor compartment 2 is cancelled in the present embodiment, so that cold air can enter the compressor compartment 2 from the rear of the compressor compartment 2 to increase the air inlet area, and further, through the separation of the wind shield 12, the air inlet path and the air outlet path of the compressor compartment 2 can be separated to avoid mixing of air.

[0089] Furthermore, in this embodiment, an air inlet is also provided at the bottom of the press chamber 2 so that the press chamber 2 is connected to the external space below the box body 1 through the air inlet.
