The integrated water-cooled motor casing has the beneficial effects that: the product is stable in size, and compact and beautiful in shape and structure; the cross section of the stainless steel cooling water pipe can be shaped into oval or various kinds of special-shaped according to the wall thickness and shape of the motor outer shell, thereby effectively reducing the wall thickness of the product, reducing the product weight, and effectively enlarging the area of cooling water; and the casing and the stainless steel cooling water pipe are integrally made of aluminum alloy by low-pressure casting molding, the stainless steel cooling water pipe has a sealing function, and the cooling water pipe is integrally coated by the casing processed by using aluminum alloy.
Description
Technical field
The utility model relates to a kind of water cooling motor housing, and more specifically, it relates to a kind of electric automobile one water cooling motor housing.
Background technology
Along with global energy problem and environment for human survival constantly worsen, to auto industry, sustainable development has proposed stern challenge.Electric automobile is undoubtedly future automobile technology important development direction as new-energy automobile, and one of key technology of electric automobile is exactly motor driven systems.Motor is as its performance requirement of core component of motor driven systems: power to volume ratio is large, and output torque is large, uses that electric current is little, overload capacity strong, the operating state such as work under bad environment and applicable frequent starting, acceleration, braking.Particularly motor in the course of the work, electric machine stator iron, stator winding in the course of the work all can produce power loss, these losses are outwards dispersed with the form of heat, need effective coolant and the type of cooling to take away heat, guarantee motor safe and reliable operation in a stable cold cycling balance sysmte.Electromotor cooling system designs to obtain the fine or not direct safe operation that affects motor.Along with the improper development of science and technology, motor is cooling by the original naturally cooling and air-cooled motor casing water-cooling heat radiating system that rises in recent years.Although motor casing water-cooling heat radiating system is cooling more remarkable than air-cooled and natural cooling effect, mechanically-sealing apparatus, water circulation system complex structure, particularly exists and leaks hidden danger, if there is seepage, can cause electrical machine insulation to destroy motor damage.The water-cooling circulating system of all motor casings seems by for important.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and has increased flow, has improved efficiency, has reduced energy consumption, saved resource, meets the servomotor twin shaft pumping system of ultra-large type injection molding machine demand simultaneously.
This electric automobile one water cooling motor housing, comprise casing and stainless steel cooling water pipe, described stainless steel cooling water pipe is located at the inner described stainless steel cooling water pipe of casing and is along the circumferential direction looped around in the shape of a spiral in casing according to motor stator winding direction and stator core length, curve differ each long 10 millimeters, Length Ratio two ends unshakable in one's determination of helical form pitch, the sealing cooling water pipe that water inlet communicates completely with delivery port.
As preferably: the cross section of described stainless steel cooling water pipe is oval.
The beneficial effects of the utility model are:
1. compact attractive in appearance, the circle diameter direction of stable, the contour structures of product size increases that reinforcement is flexible and changeable, foundry goods is good through heat treatment machinery performance;
2. in the situation that assembly welding water cooling motor housing net weight is constant relatively, blank drops to 10.2KG by original 12.7KG, by 10 original procedures, be simplified to present 5 procedures, only have original 1/3rd process time, saved raw material and process time, reduced energy waste and greatly reduce cost;
3. can stainless steel tube to be shaped to cross section according to motor housing wall thickness and shape be oval or all kinds of abnormity to stainless steel cooling water pipe pipe section, effectively reduce product wall thickness and alleviate product weight, effectively increased cooling water area, particularly stainless steel cooling water pipe itself is the closed cycle system that water inlet communicates completely with delivery port, water-cooled partial design is circumferential water route, helical form current, water-cooled part is slightly longer than stator core, water route is level and smooth, resistance is little, energy loss is few, cooling water goes out from water inlet intake-outlet, guarantee that like this recirculated water is full of whole inner chamber, make the water of water-cooling system inner chamber in full state, the inner chamber that recirculated water is all full of water-cooling system can also reduce the air in water channel to greatest extent, stator is fully dispelled the heat, the heat that the motor long time running that can effectively scatter and disappear produces.
4. casing and the moulding of stainless steel cooling water pipe integral Al-alloy low pressure casting, stainless steel cooling water pipe own just has the integral body parcel of sealing function processing casing aluminium alloy to cooling water pipe.Even if work long hours, also do not have cracking, solder joint comes off, and product is used the other defects such as distortion.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
Description of reference numerals: casing 1, stainless steel cooling water pipe 2, wire outlet seat 3, water inlet 4, delivery port 5.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model is described in connection with preferred embodiment, should know, do not represent that the utility model is limited in described embodiment.On the contrary, the utility model is by alternative, modified model and the equivalent contained in the scope of the present utility model that can be included in attached claims restriction.
As shown in Figure 1 to Figure 2, the one water cooling motor housing of the present utility model way that breaks traditions, casing 1 and stainless steel cooling water pipe 2 integral Al-alloy low pressure castings, comprise casing 1, stainless steel cooling water pipe 2, wire outlet seat 3, water inlet 4 and delivery port 5.First can stainless steel tube to be shaped to cross section according to motor housing wall thickness and shape be oval or all kinds of abnormity to stainless pipe, then according to motor stator winding direction and stator core length along the circumferential direction in the shape of a spiral around casing 1, curve differ each long 10 millimeters, Length Ratio two ends unshakable in one's determination of helical form pitch, the sealing cooling water pipe that water inlet 4 communicates completely with delivery port 5.After stainless steel cooling water pipe 2 is carried out, water inlet 4 and delivery port 5 respectively add 2 location plugs, casing 1 is when low pressure casting, after 2 preheatings of stainless steel cooling water pipe, by water inlet and delivery port location plug, be positioned at completely in mould, then start casting complete casing 1 and stainless steel cooling water pipe 2 integral Al-alloy low pressure castings.Cast blank out carries out T6 processing to foundry goods afterwards, and then blank goes out finished product according to casing drawing dimensioned.Finally block delivery port, water inlet is filled with 30 minutes ne-leakages of 0.5MP compressed air pressurize, has completed the manufacture of whole electric automobile one water cooling motor housing after qualified without pressure drop.
