A kind of PCB baking box energy-saving device for utilizing waste heat
Technical field
The utility model relates to printed wiring board manufacture technology field, in particular a kind of PCB baking box energy-saving device for utilizing waste heat.
Background technology
At present in the industry in PCB manufacturing process, have a plurality of operations and use heated-air circulation roaster and carry out baking-curing, this kind of heated-air circulation roaster, principle is as follows:
1, an air inlet is designed in baking box one end, and air inlet below mounting heater makes the air heating that enters, and reaches the needed temperature of baking;
2, the other end of baking box designs an air outlet, uses motor that the hot blast in baking box is extracted out, while making to toast the waste gas utmost point of PCB generation in baking box, discharges;
3,, because suction opeing has motor strong drawing, make air pressure in baking box and ambient pressure produce draught head, so air inlet can constantly supplement fresh air from the external world, and flow in baking box through heater;
4, so constantly circulation, makes roasting the temperature inside the box even, during the produced simultaneously Litter utmost point, discharges.
Yet there is certain deficiency in said structure:
(1) air inlet is to separate design with air outlet, and when in baking box, hot blast is pumped, what from air inlet, supplement is cold wind room temperature condition;
(2) the fresh Feng Wen Du more covering from air inlet is low, and through when hot device, the energy consumption of required heating is larger;
(3) simultaneously, the heat energy that hot blast is taken away utilizes, waste heat energy.
Therefore, prior art haves much room for improvement and improves.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of PCB baking box energy-saving device for utilizing waste heat, is intended to solve the low problem of existing PCB baking box heat utilization rate.
The technical solution of the utility model is as follows:
A PCB baking box energy-saving device for utilizing waste heat, wherein, comprises an outside air inlet, the air draft passage for used heat wind in baking box is discharged, air intake passage and the thermal insulation layer for blowing in baking box;
Wherein, described outside air inlet is connected with air intake passage, and air draft passage is set in air intake passage, and the outer setting of air intake passage has a thermal insulation layer.
Described PCB baking box energy-saving device for utilizing waste heat, wherein, described air intake passage is circular channel, and on described circular channel, is distributed with fan-shaped aluminium alloy edge strip.

Described PCB baking box energy-saving device for utilizing waste heat, wherein, the wall of described air intake passage adopts steel plate with baking paint.
PCB baking box energy-saving device for utilizing waste heat provided by the utility model, it comprises an outside air inlet, the air draft passage for used heat wind in baking box is discharged, air intake passage and the thermal insulation layer for blowing in baking box; Outside air inlet is connected with air intake passage, and air draft passage is set in air intake passage, and the outer setting of air intake passage has a thermal insulation layer.Utilize the hot blast that air draft passage is drained to heat the wind of air intake passage, save heating energy consumption, reduced power consumption, make waste heat be recycled utilization, through overtesting, find, can realize and save electric energy 30-50%.
Accompanying drawing explanation
Fig. 1 is the front view of the preferred embodiment of PCB baking box energy-saving device for utilizing waste heat of the present utility model.
Fig. 2 is the side schematic view of the preferred embodiment of PCB baking box energy-saving device for utilizing waste heat of the present utility model.
Embodiment
The utility model provides a kind of PCB baking box energy-saving device for utilizing waste heat, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
See also Fig. 1 and Fig. 2, it is the schematic diagram of the preferred embodiment of PCB baking box energy-saving device for utilizing waste heat of the present utility model.As shown in the figure, described PCB baking box energy-saving device for utilizing waste heat comprise an outside air inlet 100, for air draft passage 200 that the interior used heat wind of baking box 10 is discharged, for the air intake passage 300 to baking box 10 interior air-supplies and thermal insulation layer 400; Wherein, described outside air inlet 100 is connected with air intake passage 300, and air draft passage 200 is set in air intake passage 300, and the outer setting of air intake passage 300 has a thermal insulation layer 400.
Specifically, when air draft passage 200 is discharged the interior used heat wind of baking box 10, outside wind enters in described air intake passage 300 by outside air inlet 100, the wind filling into through out-of-date, carries out heat exchange with the hot blast in air draft passage from air draft passage 200 outsides: the cold wind that goes heating to cover with the hot blast of taking away.Thereby improve the temperature of the wind filling into, save heating energy consumption.
Design key of the present utility model is: air inlet and suction opeing are combined, and in air draft passage outside design one deck hollow passageway, this passage passes through while mending wind for the external world; Owing to covering the passage that row cold wind drains from hot blast, pass through, the cold wind that the available hot blast of taking away goes heating to cover: use the hot blast of draining to heat owing to covering before the cold wind of baking box enters baking box, therefore can reach energy-conservation, reduce power consumption, make waste heat be recycled the advantage of utilization, save electric energy 30-50%.
Further, in order to facilitate fabrication design, in the present embodiment, described air intake passage 200 is circular channel, and on described circular channel, is distributed with fan-shaped aluminium alloy edge strip 210, as shown in Figure 2.Circular air exhaust passage adopts the good aluminum alloy material of thermal conductivity, and is distributed with fan-shaped aluminium alloy edge strip, increases hot-air channel surface area, and hot blast is by entering, and aluminium alloy passage is just equivalent to a heat dish.The Hot-blast Heating being discharged due to interior aluminium alloy channel surface, the fresh wind therefore covering from the external world when by aluminum alloy heat dish, the useless Hot-blast Heating being discharged from.
