Technical field
A kind of a kind of the present invention relates to heat abstractor, more particularly to motor inverter heat abstractor.
Background technology
General cotton mill workshop bad environments, environment temperature is high, dust is big, also float many yarn suedes in air or
Felt etc..The spinning machine of operative is all configured with substantially motor and adds general General Converters, and frequency converter is due to using
During can produce amount of heat, these heats need to discharge in time, adopt radiator inside which, then by overhead fan outward
Exhausting, from lower end, air intake reaches cooling-down effect.But the heat abstractor of this universal frequency converter has at least once two
Individual shortcoming：1., as lower end air intake is open type, yarn suede, felt and dust in air etc. are easily entered in frequency converter
Portion, causes air intake vent to block, and affects the debris such as radiating effect, yarn suede not clear up in time, radiator occurs and damages or even cause
The situation that whole frequency converter burns happens occasionally.2., for this radiating structure of frequency converter is due to being lower end air intake, frequency converter is straight
Connect and be placed on table top or ground, the yarn suede or felt of the sedimentation on table top or ground are more easy in frequency converter
Portion causes radiating not in time, and reduces the service life of frequency converter.
The content of the invention
The technical problem to be solved is：A kind of motor inverter heat abstractor is provided, the heat abstractor can have
The impurity such as yarn suede or felt that prevent of effect are entered in frequency converter, are not only increased radiating efficiency, and are guaranteed that frequency converter is steady
It is fixed to work, extend its service life.
For solving above-mentioned technical problem, the technical scheme is that：A kind of motor inverter heat abstractor, including radiating
Casing, the motor inverter are fixed in heat radiation box, are provided with air outlet, the heat dissipation tank at the top of the heat radiation box

Air inlet is arranged at the bottom of heat radiation box and/or sidepiece, and the air inlet is detachably provided with air inlet filtering device, described
The position of motor inverter is in the air channel between air outlet and air inlet.
Used as a kind of preferred scheme, the heat radiation box includes upper box and lower box, and the lower box is fixed on
The bottom of casing and with upper box inner space, the motor inverter is fixed in top box body, and the air inlet is arranged at down
The bottom of casing and sidepiece, the gross area of the air inlet is less than 1/5th of nowel body surface area.
Used as a kind of preferred scheme, the air inlet filtering device includes screen pack, and the edge of the screen pack is provided with
Fixing hole, the edge of the screen pack are detachably fixed with lower box by tapping screw.
Used as a kind of preferred scheme, the air inlet of the lower box is provided with the deep gouge with screen pack form fit,
The depth of the deep gouge is equal to the thickness of screen pack, and the screen pack is removably mounted in deep gouge.
Used as a kind of preferred scheme, the screen pack is metal or the screen pack of plastic material, the net of the screen pack
Hole aperture is equal.
As a kind of preferred scheme, the screen pack on the base plate and side plate of lower box respectively with corresponding base plate and side plate
It is molded as one, the base plate and side plate of the lower box are removably mounted on lower box.
After employing above-mentioned technical proposal, the effect of the present invention is：The heat abstractor compares the radiating of current frequency converter
Possesses advantages below：1. in heat radiation box, heat radiation box keeps air flow, frequency conversion using the cooling fan moment to frequency converter
The heat that device is produced all is pulled away, good heat dissipation effect, it is ensured that frequency converter stable operation；2. the air inlet of heat radiation box be provided with into
Wind filter, can effectively filter out the magazines such as yarn suede outside heat radiation box, felt, make frequency converter relative in one
In clean environment, it is to avoid magazine to enter directly into that cause in frequency converter radiating bad；3. air inlet filtering device and heat radiation box
Detachable to install, easy cleaning so ensures that frequency converter is run under a good heat dissipation environment for a long time, and prolongation uses the longevity
Life.
Again as the heat radiation box includes upper box and lower box, the lower box be fixed on the bottom of upper box and with
Upper box inner space, the motor inverter are fixed in top box body, and the air inlet is arranged at the bottom and side of lower box
Portion, less than 1/5th of nowel body surface area, split-type structural is convenient to install frequency converter and group to the gross area of the air inlet
Dress, and the area of air inlet can have enough wind-force using the premise of relatively low cooling fan.
Again as the air inlet of the lower box is provided with the deep gouge with screen pack form fit, the depth of the deep gouge
Equal to the thickness of screen pack, the screen pack is removably mounted in deep gouge, the deep gouge can facilitate the accurate fixed of screen pack and
Install, while also making the flush of lower box, profile is more attractive in appearance.
