Abstract

The invention provides a semiconductor refrigeration assembly and a refrigerator. The refrigerator comprises a refrigerator body and the semiconductor refrigeration assembly. The semiconductor refrigeration assembly is arranged on a target side wall of the refrigerator body. The semiconductor refrigeration assembly is arranged vertical. An air channel structure is formed in the inner wall on the back of the refrigerator body. An air channel communicates with a storage bin of the refrigerator body. A cold side radiator is located in the air channel. A cold side fan is further arranged in the air channel. According to the scheme of the semiconductor refrigeration assembly and the refrigerator, after a semiconductor chilling plate refrigerates, cold energy is transmitted to the cold side radiator through a cold conduction block; because the cold side radiator is used as a cold side evaporation device, and an aluminum liner is omitted, under the action of the cold side fan, cold energy evaporated by the cold side radiator carries out thermal exchange with air in the storage bin of the refrigerator through air convection, the thermal exchange efficiency can be improved, and by adoptingthe manner of air convection, articles in the storage bin can be cooled even, and refrigeration is quicker.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a semiconductor refrigeration assembly and a refrigerator. Background technique [0002] At present, the direct cooling type is the mainstream in the market for mini refrigerators and mini heating and cooling boxes. The existing semiconductor refrigeration chip cooling method generally uses aluminum liner as the heat exchange device. The heat exchange principle is through the contact between the item and the inner wall of the storage compartment. , for direct conduction heat transfer. However, many items stored in the storage bin have irregular shapes, the contact area with the aluminum liner is also small, and the heat exchange efficiency is low. Contents of the invention [0003] Embodiments of the present invention provide a semiconductor refrigeration assembly and a refrigerator to solve the problem of low heat exchange efficiency in the prior art. [0004] In the f...
