- With the development of society and economy and the improvement of people's living standards, refrigerators have also become indispensable household appliances in people's daily lives. Existing refrigerating compartments of refrigerators have diversified appearances and different width requirements on air ducts. During research and development of some refrigerators, it is often only necessary to modify the appearance of the air duct and the appearance of interior trimmings. However, the air duct needs to transmit air to an air outlet, so when the air duct is widened, foam of a heat insulation layer inside needs to be widened. If the heat insulation layer is not widened, cold air will directly pass through a plastic cover plate, and may cause condensation. Therefore, an inner liner cooperating with the heat insulation layer to achieve a fixation effect also needs to be widened and modified, resulting in new mold opening for the air duct and new mold opening for the corresponding inner liner of a cabinet, which causes great cost input of molds. And management waste is caused by too many air ducts and cabinets. In addition, management confusion easily occurs.

The splitter plate is divided into two lateral air ducts with opposite air flow directions, and each side air duct is divided into several split air ducts with the same wind flow direction by at least one secondary splitter plate. There are several positioning columns, and the positioning columns pass through the drainage plate and the corresponding through holes on the cover plate in turn, and the end of the positioning column protruding from the cover plate is equipped with a locking bolt; the other surface of the positioning plate is fixed.
