As shown in fig. 2, the refrigeration apparatus 100 further includes a two-channel refrigeration system, where the two-channel refrigeration system includes an evaporator 5 provided with a coil group 501, and an air duct 7 in thermal contact with the coil group 501, where the air duct 7 is provided with an air inlet 701 and an air outlet 703 that are respectively communicated with the storage compartment 3, so that air in the storage compartment 3 enters the channel of the air duct 7 to exchange heat with the refrigerant in the coil group 501.

Specifically, the dual-channel refrigeration system comprises an evaporator 5 arranged in a direct cooling mode, and further comprises a compressor 9, a capillary tube 11, a dry filter 13 and a condenser 15, wherein the compressor 9, the evaporator 5, the capillary tube 11, the dry filter 13 and the condenser 15 are sequentially connected to form a refrigeration loop, so that refrigerant circulates in the refrigeration loop, and refrigeration capacity is continuously provided for the storage compartment 3.

Specifically, there are various ways in which the air duct 7 is in thermal contact with the coil group 501, and in this embodiment, the air duct 7 is attached to the coil group 501, for example, by welding or taping. In other embodiments of the present invention, the air duct 7 may be wound around the coil 501, so that the air duct 7 and the coil 501 can exchange heat more sufficiently. If the air duct 7 is in thermal contact with the coil assembly 501, the air duct 7 is preferably made of a relatively high-toughness metal material, such as aluminum.

In the embodiment of the present invention, the air duct 7 is a pipeline provided with the air inlet 701 and the air outlet 703, and the air inlet 701 and the air outlet 703 are respectively communicated with the storage compartment 3, and it can be understood that in the present invention, the inner container 103 of the refrigeration device 100 is respectively provided with a channel for the air inlet 701 and the air outlet 703 to be communicated with the storage compartment 3, so that air in the storage compartment 3 enters the air duct 7 through the air inlet 701 and then exchanges heat with the refrigerant in the coil pipe group 501, and cooled air is uniformly discharged into the storage compartment 3 through the air outlet 703, thereby realizing a dual-channel refrigeration mode combining direct cooling and air cooling, so that the heat exchange efficiency of the evaporator 5 is high, the energy consumption is low, and meanwhile, the refrigeration is more uniform and is not easy to frost, thereby overcoming the defects of the existing two modes of direct cooling refrigeration and air cooling refrigeration.

In one embodiment of the present invention, the air inlet 701 is disposed at a lower portion of the storage compartment 3, and the air outlet 703 is disposed at an upper portion of the storage compartment 3. Since the air outlet 703 is located at the upper portion of the storage compartment 3, the cooled air is discharged from the upper portion of the storage compartment 3, the cooling capacity is gradually filled and expanded into the whole storage compartment 3, and the air after heat exchange with the stored articles enters the air pipe 7 through the air inlet 701 at the lower portion of the storage compartment 3 for cooling again, thereby ensuring the cooling effect inside the cooling device 100.
