The front-end and back-end of described deflector all link into an integrated entity with the inwall of heat exchange case, and the inwall of bottom and Zhong You one end, top and heat exchange case links into an integrated entity, thereby the inwall of the other end and heat exchange case keeps certain distance to form described ventilating opening.
The front end of described deflector, rear end, top and bottom all link into an integrated entity with the inwall of heat exchange case, and offer described ventilating opening in top or the bottom of deflector, and this ventilating opening is rectangular or circular.
The ventilating opening gross area on described every deflector equals the cross-sectional area of fan outlet, also equals the cross-sectional area of described airduct.
Operation principle of the present utility model is: operation principle of the present utility model and existing oven heating device for gravure press are basic identical, difference is that heat exchange air duct of the present utility model is continuous S shape, blower fan blasts the air of heat exchange case need to be through after a plurality of heat exchange air duct heat, could send into baking oven from airduct, coiled material printing surface is carried out to heating, drying.
The beneficial effects of the utility model are: the utility model utilizes deflector in heat exchange case, to be separated out several heat exchange air duct, the dislocation up and down of recycling ventilating opening is arranged, a plurality of heat exchange air duct are connected into a continuous S shape air channel, make air tortuous flowing (as shown in Figure 4 in air channel, in figure, arrow is air-flow direction), extended the time that air stops in heat exchange case, effectively promote the heat exchanger effectiveness of heat exchange case, thereby reach the object of saving the energy, improvement part is realized also fairly simple, and the cost compare of making is low.
