The purpose of this utility model solves the deficiencies in the prior art, provides a kind of flue reflow soldering cooling device.
A kind of technical scheme of the present utility model:
A kind of flue reflow soldering cooling device, the lower furnace comprising upper furnace and removably connect with upper furnace, upper furnace sidewall is provided with air inlet, the upper surface of upper furnace is provided with air outlet, the first volute be communicated with air inlet and the second volute be communicated with air outlet is provided with inside upper furnace, be provided with pressure fan in described first volute, in described second volute, be provided with air exhauster; Also comprise the boxboard for covering the first volute and the second volute, boxboard is provided with the through hole be communicated with the first volute air outlet, boxboard both sides of the edge are provided with the first return air inlet, the one-level cowling panel for disperseing wind is provided with directly over through hole, and there is gap between through hole and one-level cowling panel, also comprise the secondary cowling panel for covering boxboard, secondary cowling panel is positioned at directly over one-level cowling panel and the both sides of the edge of secondary cowling panel are provided with the second return air inlet, form air channel between secondary cowling panel and boxboard, air channel is communicated with the second volute.
A kind of preferred version is that air outlet place is provided with collecting box, and collecting box is in communication with the outside.
A kind of preferred version is that air inlet is provided with shutter.
Comprehensive technique scheme is known, the utility model has following beneficial effect: because the cooling zone in upper furnace adds the second volute, second volute can extract the air being drawn into cooling zone from the first volute out in a large number, air will take away the hot gas on pcb board surface, improve pcb board cooling velocity, achieve the balance of air intake and air-out simultaneously.It is reliable that the utility model also has compact conformation, and running is simple.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to technological means of the present utility model can be better understood, and can be implemented according to the content of description, and can become apparent to allow above and other object of the present utility model, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
