Abstract
The name of the invention is a cooling system structure of a water cooling motor base, particularly relates to a cooling system structure of a water cooling motor welding base used for driving an electric automobile, and mainly solves problems that steel plate coiling welding is performed on the internal cylinder of the existing cooling system structure of the water cooling motor base, end plate tailor-welding is performed at the two ends of water channels, water is liable to seep at the welding seams of the internal cylinder of the base and the tailor-welding seams of the end plates of the two ends and burning loss of a motor is caused. The internal cylinder of the base adopts an integral circular pipe. Water channel ribs are fixed in the groove of the internal cylinder of the base, the external cylinder of the base hot-sleeves the external circle of the water channel ribs, and two girth welding seam sealing water channels are welded at the step lapping part of the two ends of the external cylinder of the base and the internal cylinder of the base. The internal cylinder of the base and the sealing steps of the two ends of the water channels are machined by the same hot-rolling seamless steel pipe without splicing welding seam so that burning loss of the motor caused by water seeping into the internal part of the motor from the internal cavity of the base can be avoided. Besides, the cooling system structure of the water cooling motor base also has advantages of being simple in manufacturing process and low in deformation after internal hole machining of the base.
Description
Technical field
The present invention relates to a kind of cooling system structure of water-cooled machine support, relate to a kind of cooling system structure of electric automobile driving water-cooled machine welding frame specifically.
Background technology
Drive motors provides power for electric automobile, and its volume is by the restriction of installing space, and weight is by the restriction of car load.Adopt higher electromagnetic load during usual drive motors design, the loss produced when drive motors is run is higher, and caloric value is large, and the therefore good type of cooling is the key point of motor reliability service.The type of cooling of current drive motors mainly contains following several: cooling, forced air cooling, self-ventilation, water-cooled naturally.Compared with other type of cooling, under equal-wattage grade, use the drive motors of water-cooling, have a lot of advantage: small volume, lightweight, raw-material utilance is relatively high.
It is roll of steel plate weldering that the structure of the Water-cooling Welding earthing of frame of current water-cooled machine industry universal mostly is support inner core, and the weldering of inner core excircle or processing water channel, support outer wall is roll of steel plate weldering or welding, and inside and outside cylinder two ends end plate and inside and outside cylinder welding are to seal cooling water channel.Above-mentioned support cooling system structure, there is complex procedures, weld seam is many, welding process requirement is high, process and the shortcomings such as support Internal Hole Deformation amount is large in follow-up use procedure, particularly all require as far as possible little to this volume and weight, but cooling effect requires that higher electric automobile drives water-cooled machine, in support, after hole machined, inner tube wall only has 4 ~ 6mm thick usually, inner core welding seam and connect with end plate the close property of commissure matter good layer substantially processed fall, residue layer slightly defect, even a pore, also cooling water can be made to infiltrate motor internal, cause motor burning.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide that a kind of manufacturing process is simple, support inner core deflection is little, cooling system water-stop is good, guarantees that cooling water can not enter motor internal and cause the cooling system structure of the electric automobile driving water-cooled machine welding frame of motor burning.
Technical solution of the present invention is: support inner core adopts Integral-type round pipe, water channel muscle is fixed in the groove of support inner core, support urceolus hot jacket is on the cylindrical of water channel muscle, and the step lap-joint at support urceolus and support inner core two ends is welded with two girth joints and seals water channel.
Support inner core described in technical solution of the present invention adopts hot rolled seamless steel tube, is provided with the groove of fixing water channel muscle in the middle part of support inner core, and two ends are provided with the step of sealing water channel.
Water channel muscle described in technical solution of the present invention is at the cooling water circulation water channel of the S type that circumferentially formed of support inner core.
Support inner core of the present invention processes by same seamless steel pipe owing to adopting its endoporus and water channel two ends sealed step, without splicing welding joint, the welding ring-shaped fillet weld processed only is not needed at step arranged outside two postweldings connected and seal of support urceolus and support inner core fit, avoid and cause motor burning from the support inner chamber motor internal that seeps water, also there is manufacturing process simple, the advantages such as after hole machined deflection is little in support.
