Abstract
The utility model relates to a face-to-face blowing type wind cooling device, which is characterized in that a suction blower is provided above a cooled work-piece and a blower is provided beside the suction blower. The utility model has the advantages of simple structure and excellent cooling effect and, besides, has little influence on ambient areas out of the working region.
Description
Technical field
The utility model relates to a kind of air cooling equipment, particularly a kind of oppositely-blowing air cooling equipment that is used for the hot blast welding machine.
Background technology
In the air flue device in hot air reflow welding machine of electronics assembling automatic assembly line, along being provided with hot air heating apparatus and air cooling equipment in regular turn by weldering circuit board direction of advance, components and parts are housed, and enter air flue device in hot air reflow welding machine automatically in the printed circuit board (PCB) that pad locations is coated with paste solder, under the hot blast effect of hot-blast spray nozzle, printed circuit board (PCB) is locally heated and makes the paste solder fusing form solder joint, the cold wind cooling curing that is blown out by air cooling equipment immediately, influence the rising of hot zone electrical plate temperature in the existing air flue device in hot air reflow welding machine for the cold wind of avoiding cooling air unit to blow out, can only adopt and strengthen cooling air unit and the hot blast distance between chewing, must increase the time that solder joint in the motion is in molten condition yet strengthen distance, will have a strong impact on the welding quality of product.This design for hot air reflow soldering equipment has proposed a difficult problem, requires design a kind of to the little air cooling equipment of the influence of the adjacent domain outside the cooling work face, shortens cooling air unit and the hot blast distance between chewing thereby can reach.
The utility model content
Technical problem to be solved in the utility model is, at the above-mentioned deficiency of prior art, and a kind of simple in structure, good cooling results is provided, to the little oppositely-blowing air cooling equipment of the influence of the adjacent domain outside the working face.
Oppositely-blowing air cooling equipment provided by the utility model is realized by following technical scheme.
A kind of oppositely-blowing air cooling equipment is characterized in that: be provided with induced-draught fan in frame; In the other hair-dryer that is provided with of the side of induced-draught fan.
Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:
The inlet scoop of this induced-draught fan is to be located at over against the workpiece centre top that is cooled; This hair-dryer be provided with a plurality of, be distributed in induced-draught fan around, and its blowing mouth is the oblique workpiece that is cooled.
Advantage of the present utility model is:
Oppositely-blowing air cooling equipment provided by the utility model, simple in structure, good cooling results, little to the influence of the adjacent domain outside the working face.This oppositely-blowing air cooling equipment is applied to can shortening in the hot blast welding machine cooling air unit and the hot blast distance between chewing, and reduces occupation area of equipment, and improves quality of welding spot.
For architectural feature of the present utility model and effect thereof are had further understanding, enumerate specific embodiment now and be described with reference to the accompanying drawings as follows:
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of oppositely-blowing air cooling equipment provided by the utility model, it is: be provided with induced-draught fan 1 on the frame (not shown); In the other hair-dryer 2 that is provided with of the side of induced-draught fan.
The inlet scoop of this induced-draught fan 1 is to be located at over against the workpiece centre top that is cooled; This hair-dryer 2 be provided with a plurality of, be distributed in induced-draught fan 1 around, and its blowing mouth is the oblique workpiece centre that is cooled.
Above the workpiece centre that is cooled, produce negative pressure by induced-draught fan 1, and hair-dryer is close to the centre to blowing from side, wind power balance, cooling effect is remarkable, and is very little to the influence of the adjacent domain outside the working face.This kind oppositely-blowing air cooling equipment not only can be applicable in the air flue device in hot air reflow welding machine, also can be used for other every needs local air-cooled again can not be in the influential device of close region.
The above only is the utility model specific embodiment; everyly be familiar with this skill personage and make various modifications or change very easily in view of the above; therefore, all equivalence replacements that the utility model claim spirit is done that do not break away from all should be included in this patent protection range.
Claims (2)
1, a kind of oppositely-blowing air cooling equipment is used for workpiece is cooled off, and it is characterized in that: be provided with a frame, be provided with induced-draught fan in frame; In the other hair-dryer that is provided with of the side of induced-draught fan.
2, oppositely-blowing air cooling equipment according to claim 1 is characterized in that: the inlet scoop of this induced-draught fan is to be located at over against the workpiece centre top that is cooled; This hair-dryer be provided with a plurality of, be distributed in induced-draught fan around, and its blowing mouth is the oblique workpiece centre that is cooled.
