The air inlet of the air inlet duct of current baking box is directly connected with inner bag, causing outside air to enter in main box does not heat and just circuit board is toasted, cause circuit board baking inhomogeneous, the circuit board of the Ceng Jia the superiors particularly, its upper surface contacts with cold air at first, and the air of its lower surface is hot-air, cause the circuit board inequality of being heated, impact baking efficiency and baking quality.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, a kind of uniform heat distribution is provided, toasts the circuit board baking box that efficiency is high and baking quality is good.
The purpose of this utility model is achieved through the following technical solutions: a kind of circuit board baking box, comprise main box, main box is inside and outside double-layer plate body structure, between inside and outside double-layer plate, be provided with heat pipe, the crown center position of this main box arranges the intake stack of a connection air inlet duct, on intake stack, offer a plurality of ventilating openings, in described main box body, be provided with inner bag, described inner bag upper, under, left, right inside wall is distributed with a plurality of ventilation holes, and be provided with temperature inductor on the angle of inner bag surrounding, between the outer wall of inner bag and main box, be provided with airspace, in described airspace, be provided with a plurality of fans, the top of described main box is provided with the air outlet of a plurality of connection exhausting ducts, on described main box lateral wall, be provided with control cabinet, temperature inductor is connected with the thermostat signal in control cabinet.
Described air outlet is at least two, and is distributed in main box top.
In described inner bag, be provided with a layer frame, layer frame is divided into three layers by inner bag.
In the airspace at the every one deck of described inner bag two ends, be provided with a fan.
In described control cabinet, be also provided with a timing warner.
Described control cabinet top is provided with the air lock of controlling air inlet duct and exhausting duct, and the adjusting button of air lock is arranged in the outer surface of upper of main box
The utlity model has following advantage: baking box of the present utility model, air inlet duct front end connects an intake stack, on intake stack, offer a plurality of ventilating openings, make like this wind speed of cold wind slow down, make cold wind be able to abundant heating, hot blast after heating enters inner bag by ventilation hole again circuit board is toasted, and then discharge main box, hot blast is after circulation of air circulation, make uniform heat distribution in baking box, improved drying efficiency, the timing warner arranging on the temperature control inductor arranging in inner bag and main box lateral wall, can carry out constant temperature to circuit board regularly toasts, baking quality and baking efficiency have been guaranteed.
