The present invention relates to the technical field of a cooling device, and more particularly to a modularized general-purpose blower for a refrigerator, a refrigerator, and a method for manufacturing a refrigerator.

With the development of socio-economy and the improvement of people's living standards, refrigerators have become indispensable household appliances for people's daily lives. Existing refrigerators have complicated refrigerating chambers, their appearances are diversifying, and the demands for duct widths are different. When researching and developing a refrigerator, it is necessary to change only the appearance of the duct and the appearance of the interior. However, since it is necessary to send the wind to the position of the air outlet by the duct, the duct width is also expanded, and the foam width of the heat insulating layer in the duct needs to be expanded accordingly. If the width of the insulation layer is not widened, the cooling air may pass directly through the plastic lid plate and cause condensation. Therefore, it is necessary to change the liner, which plays the role of engaging and fixing it, according to the width. Then, it is necessary to design a new mold for the duct and a new mold for the corresponding box liner. For this reason, the cost to be charged into the mold becomes large, and the number of ducts and boxes is too large, which makes management difficult.
