The refrigerator is characterized in that a freezer compartment cold air return air passage, a refrigerator cold air discharge air passage, and a refrigerator cold air return air passage are provided in a vertical partition wall that partitions the storage chambers.

(Function) By adopting the above method, components such as the cooler and radiator that make up the cooling and heat dissipation system are installed together at the top of the refrigerator body, and the vertical partition wall is used to create a cold air discharge channel and a cool air outlet. By providing a return air path, the cold air generated by the cooler installed at the top of the refrigerator body will be circulated to each storage compartment, and the back side of the refrigerator body will have a cooling and heat dissipation cycle Since there are no constituent members, the structure is simple.
