Furthermore, the heating pipes are vertically arranged in a staggered manner and are longitudinally arranged in the rectangular part.
Further, the method comprises the following steps: and heat preservation and insulation asbestos layers are arranged on the side surfaces of the periphery of the air duct.
Furthermore, the lower part of the left end of the rectangular part is provided with an air guide surface.
Furthermore, the air guide surface is an inclined surface or an arc surface.
Furthermore, the input end and the output end of the heating plastic package section are both provided with door curtains.
Compared with the prior art, the invention has the following beneficial effects: simple structure, reasonable in design, motor setting are in lower part side, are favorable to thermal giving off, avoid the fan to receive high temperature heat to influence life, keep heated air circulation effect, reduce the calorific loss, and daily point is examined and is maintained conveniently.
