In this embodiment, the horizontal refrigerator is a direct-cooling refrigeration device, that is, a direct-cooling mode is adopted to cool the articles stored in the storage compartment 10.

Specifically, the refrigerating unit includes a compressor, a condenser, a throttling device, and an evaporator, which are sequentially connected, the cabinet body 1 has an inner container 12 forming the storage compartment 10 and an outer shell 11 disposed outside the inner container 12, as shown in fig. 3, and the evaporator includes an evaporation tube 2 wound outside the inner container 12; the evaporation tube 2 transmits cold energy to the storage compartment 10 in a natural radiation manner and is used for refrigerating the articles stored in the storage compartment 10.

In the prior art, since the cooling capacity is transferred from the inner wall of the storage compartment 10 (i.e., the liner 12) to the middle position of the storage compartment 10, the size of the storage compartment 10 is generally larger, and the larger size inevitably causes uneven cooling capacity in the storage compartment 10. In particular, the more cold is present at a position closer to the inner wall of the storage compartment 10.

In addition, since the storage compartment 10 is disposed with the opening upwards, and the upper side of the whole storage compartment 10 is open, the cooling capacity at the position of the opening of the storage compartment 10 is seriously dissipated outwards, and the difference between the cooling capacity at the position of the storage compartment 10 close to the opening and the cooling capacity of the storage compartment 10 close to the bottom is also caused. The cooling capacity is more and more sufficient in the area near the bottom of the storage compartment 10, and the cooling capacity is relatively insufficient at the opening position of the storage compartment 10.
