Description
Technical field
This utility model relates to a kind of motor cooling field, is specifically related to a kind of motor water-cooled device.
Background technology
The type of cooling of motor is mainly by following several at present: natural cooling, forced air cooling, self-ventilation, water-cooled, compared with other types of cooling, under equal-wattage grade, the motor of water-cooling pattern cooling is used to have volume little, lightweight advantage, the utilization rate of material is higher.
Water-cooled machine industry at present, it is roll of steel plate weldering that the structure of general Water-cooling Welding earthing of frame mostly is pedestal inner core, the weldering of inner core excircle or processing water channel, and 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 many, the shortcomings such as support Internal Hole Deformation amount is big during welding process requirement height, processing and follow-up use, particularly this volume and weight are required to the least but cooling effect and require that higher electric automobile drives water-cooled machine, in support, after hole machined, inner tube wall generally only 4 one 6mm are thick, inner core welding is stitched and couples the processed abrasion of layer that matter close property in commissure is good with end plate, residue layer slightly defect, cooling water will be made to penetrate into motor internal, thus cause motor burning.
As shown in Figure 3, prior art exists a kind of water-cooled machine support, including pedestal inner core, pedestal urceolus, water channel muscle, water channel muscle is fixed in the groove of pedestal inner core, the circumference of pedestal inner core is formed the cooling water circulation water channel of single S type, pedestal urceolus hot jacket is on the cylindrical of water channel muscle, support urceolus is provided with paddle hole, the outer drum outer wall of support is welded with into, outlet pipe, for cooling down introducing and the discharge of water, the inner core of this water cooling base uses hot rolled seamless steel tube, need not welding, solve above-mentioned inner core weld seam problem of processed destruction when with end plate connection.
Water channel muscle is welded by said mechanism with pedestal inner core, and owing to being single S type cyclic water channel, so each piece of water channel muscle is required for welding with pedestal inner core, the pad making total becomes many, in welding process, due to error or the defect of welding procedure of welder, it may appear that the phenomenon of not prison welding even pad cracking, easily seep water during long-term use, make motor burn out.
Utility model content
This utility model is intended to provide a kind of and reduces solder joint, improves the motor water-cooled device in motor service life.
Motor water-cooled device in this programme, including base and sealing plate, pedestal outer shroud it is provided with on base, pedestal outer shroud is internally provided with pedestal inner core, it is formed with annular space between pedestal inner core and pedestal outer shroud, two ends, annular space left and right are all closed by sealing plate, adjacent water filling port and outlet it is equipped with outside pedestal, between pedestal inner core and pedestal outer shroud, circumference is evenly equipped with several water cooling units, each water cooling unit includes the four outer muscle laterally set gradually, wherein first outer muscle is welded on inner seal plate, between second outer muscle and the 4th outer muscle inlaying bBase inner core and pedestal outer shroud, and between being arranged on two pieces of sealing plates, 3rd outer muscle is welded on outer side seal plate.
nullThe know-why of this programme and have the beneficial effect that pedestal outer shroud adjacent is provided with water filling port and outlet，Water filling port is adjacent with outlet be can ensure that when cooling down water and injecting whole device，Cooling water flows through whole circumference，Various piece is made effectively to cool down，Between pedestal inner core and pedestal outer shroud, circumference is evenly equipped with several water cooling units，Each water cooling unit is arranged in sequence with four outer muscle，Wherein first outer muscle is welded on inner seal plate，3rd outer muscle is welded on outer side seal plate，Second and the 4th outer muscle are embedded on pedestal inner core，Do not contact with inside and outside side sealing plate，It is being internally formed double-drainage SAPMAC method water channel with this，When motor is started working adstante febre，Now cooling water starts the cycle over flowing，Heat transmits，Cooling water can absorb a part of heat and be taken out of by partial heat along with the outflow of current，The purpose of cooling heat radiation is reached with this.
In the welding process of whole motor water-cooled device; each water cooling unit has only to weld two outer muscle without all welding; decrease the pad of half; in welding process, usually can cause weld crack and water leakage due to the welding procedure imperfection of welder, cause burning of motor; so the minimizing of pad can reduce the infiltration risk caused due to not prison welding; and be double S type cyclic water channel, adding flow when flowing, cooling effectiveness improves.
Compared with prior art, motor water cooling mechanism decreases half pad, improves the service life of motor.
Further, pedestal inner core is hot rolled seamless steel tube, and the sealing of pedestal inner core is tighter.
Further, pedestal inner core is provided with and the groove of outer muscle interference fit, uses the mode of recessing will not cause damage to bottom pedestal inner core, is increased without pad, reduces welding difficulty, and interference fit makes outer muscle be firmly secured on pedestal inner core.
Further, water filling port and outlet are arranged on pedestal outer shroud top, it is ensured that cooling water flows from the top down, is full of whole device.
