Description

The switch cubicle that is used for textile machine

Technical field

The present invention relates to the switch cubicle for textile machine, it has electronic component and the radiator that is connected with this electronic component heat conduction.This switch cubicle comprises the first Room that wherein is provided with this electronic component and the second Room that wherein is provided with radiator.At the second indoor fan that is provided with for the forced air-cooling radiator.Switch cubicle has at the first opening of exchange of air between two chambers be used for the second opening of exchange of air between the first Room and environment.Be provided with for air is sucked the 3rd opening of the second Room from environment.

Background technology

Compare with other application scenario, in field of textile machinery, switch cubicle and operating mechanism such as electronic component located therein run into special requirement.Air in the textile machine factory building is doped with many flyings, and flyings swim in for a long time airborne weaving residue by the fiber that discharges, fibre bundle, remaining yarn, dust and other maintenance and consist of on textile machine.Discharging many flyings is for example carding machine, drawing frame, fly frame, spinning machine, combing machine, loom, twisting machine or bobbin-winding machine to airborne such textile machine.

DE 3517149C2 discloses a kind of switch cubicle for textile machine.For cooling electronic components, fan is dried sideling facing to the fin of radiator.Oblique blowing should be unable to allow flyings tangle radiator, and this can adversely have influence on the cooling effect.For the additional cooling chamber that wherein is provided with electronic component, proximally be provided with air outlet slit in downstream and radiator interval.The cold air stream that is produced by fan flows away through this outlet, and its negative pressure is aspirated out air from the chamber that electronic component is housed thus, and described air flows through this air outlet slit and collaborates with cold air stream.In order to compensate again the air that suction is walked, be provided with the air intake with filter on other position, air can flow into the chamber that electronic component is housed through this air intake.Even air can replenish flow into through air intake, air is sucked away through air outlet slit all the time, and indoorly always there is slight negative pressure in result what electronic component was housed.Be not absolutely to seal because in fact be used to the switch cubicle of textile machine, so although filter is arranged before air intake, the air that contains flyings still can enter this chamber.Along with passage of time, this causes element dirty and may have influence on the function of element.

Summary of the invention

Therefore, task of the present invention is, except the forced air-cooling of the second indoor radiator, also guarantees the cooling of the first indoor electronic component by plain mode, do not enter the first Room but do not have flyings.

According to the present invention, complete this task by the characteristic feature of claim 1.Favourable improvement project of the present invention is the theme of dependent claims.

In order to complete this task, these two chambers so arrange, at least part of below that is positioned at the first Room, the second Room.According to the present invention, be provided for that the first opening of exchange of air is arranged in the underside area of the first Room between two chambers, and be provided for that the second opening of exchange of air is arranged in the upper-side area of the first Room between the first Room and environment.In addition, the first opening and fan so arrange, that is, fan forces air to enter the first Room through the first opening.The 3rd opening is equipped with filter, and this filter is avoided entering the second Room from the flyings of environment.

Switch cubicle of the present invention provides following possibility, indoorly produces at least slight malleation at first of switch cubicle.Due to this malleation being arranged, flyings can not enter this chamber.Solution of the present invention does not need the fan that adds.Same fan is used to coolingly comprise the first Room of electronic component and be used to produce malleation, and this fan has also guaranteed the forced air-cooling of radiator.But, following means are not enough to complete separately this task, and the first opening and fan so arrange, fan forces air to enter the first Room through the first opening.Cooling and stop at the first indoor focus that occurs for the Homogeneouslly-radiating of realizing the first Room

According to the present invention, the first opening is arranged in the underside area of the first Room, and the second opening is arranged in the upper-side area of the first Room.Therefore, cold air can flow into the first Room and be heated by electronic component from the below.Because the air after heating must rise, so this air can be seen off by the second opening of being located at the top reliably.In order to obtain the described layout about the first opening, these two chambers so arrange, that is, and and at least part of below that is positioned at the first Room, the second Room.

Guarantee the suction cold air by the 3rd opening, not only be used for radiator, and be used for electronic component.

For air is blowed out to environment from the second Room, can be formed with the 4th opening.

Radiator advantageously has a plurality of fin.By fin, enlarged the surface and the heat radiation be improved.Also can adopt the radiator as knowing from prior art.

According to a preferred embodiment of the present invention, these fin have the common setting like this of vertical and this fan and the second Room and so consist of, and, are parallel to this longitudinal flow by the air of fans drive that is.Guaranteed best cooling under this air guide mobility status.Perpendicular to vertically or when flowing with respect to this fore-and-aft tilt ground guiding of fin, may heating stronger zone occur at air because of air eddy, cooling or heat radiation can variation.When mobile, can basically avoid such air eddy when the air parallel conductive.

According to another preferred implementation, the both sides of the second Room and the first Room are adjacent, and are used for the 3rd opening of air intake the second Room is arranged in the zone of the first side, and radiator is arranged in the zone of the second side.By suction opening and radiator being arranged in not on homonymy, can select enough large suction opening to suck needed air.Leave enough places at opposite side and flow to radiator and sufficient air guide, so that the radiator heat radiation.

The size of the first opening can be regulated.In this way, can regulate the air capacity that is forced into the first Room also makes air capacity be adapted to needed heat radiation and needed malleation thus.

Description of drawings

Describe the present invention in detail below with reference to embodiment shown in the drawings, wherein:
