DRYING APPARATUS AND COATING DEVICE

The present application provides an oven drying apparatus and a coating device, which relate to the technical field of batteries. An oven drying apparatus comprises an oven drying chamber and a heating assembly. The oven drying chamber is used for accommodating a to-be-oven-dried member, the oven drying chamber having a first oven drying side facing the to-be-oven-dried member, with the first oven drying side having a plurality of first air inlet portions for fluid medium to enter the oven drying chamber. The heating assembly is disposed on the first oven drying side, and the heating assembly is configured to oven-dry the to-be-oven-dried member. The first oven drying side is further provided with an air return portion, at least one air return portion being provided between two adjacent first air inlet portions, and the air return portion being configured for fluid medium in the oven drying chamber to be discharged from the oven drying chamber. The arrangement of an air return portion between two first air inlet portions can discharge fluid medium between the two first air inlet portions and take away the heat, thus avoiding accumulation of heat between the two first air inlet portions and improving the heating uniformity of the to-be-oven-dried member.
