The embodiment of the utility model provides a: as shown in fig. 1 to 7, a horizontal refrigerator is disclosed, which comprises a cabinet body 1 having a storage space 10, a refrigerating unit disposed on the cabinet body 1, and a door body for opening or closing an opening of the storage space 10, wherein the storage space 10 is disposed to be opened upward. In this embodiment, the horizontal refrigerator is a direct-cooling horizontal refrigerator, that is, the direct cooling mode is adopted to cool the articles stored in the storage space 10.

Specifically, the refrigerating unit comprises a compressor, a condenser, a throttling device and an evaporator which are connected in sequence, the cabinet body 1 is provided with an inner container 11 forming the storage space 10 and a shell 12 arranged outside the inner container 11, and as shown in fig. 3, the evaporator comprises an evaporation tube 2 wound outside the inner container 11; the evaporator tube transmits cold energy into the storage space 10 in a natural radiation mode and is used for refrigerating articles stored in the storage space 10.

In the prior art, the cold energy is transmitted from the inner wall of the storage space 10 to the middle, the size of the storage space 10 is generally large, and the large size inevitably causes the uneven cold energy in the storage space 10, and the more the cold energy is sufficient at the position closer to the inner wall of the storage space 10. In addition, because the storage space 10 is arranged towards the upper opening, and the upper side of the whole storage space 10 is an opening, the cold quantity at the opening position of the storage space 10 is relatively seriously dissipated outwards, and the difference between the cold quantity at the position of the storage space 10 close to the opening and the cold quantity at the position of the storage space 10 close to the bottom can be caused, specifically, the more the cold quantity is in the region close to the bottom of the storage space 10, the less the cold quantity is in the opening position of the storage space 10.

In this embodiment, in order to make the cooling capacity in the direct-cooling horizontal refrigerator more uniform, a temperature equalizing module 3 is further disposed in the storage space, the temperature equalizing module has a housing 31 positioned in the storage space 10, a gap portion 100 is formed between the bottom of the housing 31 and the bottom of the storage space 10, and the temperature equalizing module 3 further has a heat conduction unit disposed in the housing 31, and the heat conduction unit is configured to transfer the cooling capacity at the bottom of the storage space 10 to an opening position of the storage space 10.

In this embodiment, the cold quantity at the bottom of the storage space 10 is transferred to the opening position through the arrangement of the heat conduction unit, the cold quantity at the opening of the storage space 10 can be rapidly supplemented after the door body is opened, and the insufficient cold supply caused by the loss of the cold quantity at the opening of the storage space can be avoided. Meanwhile, since the gap portion 100 is provided between the temperature equalizing module 3 and the bottom of the storage space 10, the temperature equalizing module 3 is actually provided in an overhead manner. The gap part arranged at the bottom of the heat conduction unit can facilitate the flowing and gathering of ambient cold at the bottom of the heat conduction unit, so that the cold can be better transferred from the bottom of the storage space 10 to the opening position of the storage space 10.

In a specific embodiment, as shown in fig. 3, the temperature equalizing module 3 is positioned on an inner wall of the storage space 10 and detachably fixed on the inner wall of the storage space 10.
