Preferably, the helix tube of described cooling water pipe is uniformly distributed from one end of described motor to the other end.
Preferably, described coolant by drive unit at described cooling Bottomhole pressure.
Preferably, described coolant is specially cooling water, and described drive unit is specially water pump.
Preferably, described water pump and motor are connected to same controller.
The present invention also provides a kind of electric motor car, comprises the motor described in above-mentioned any one.
The motor of electric motor car provided by the present invention, comprise motor and cooling water pipe, cooling water pipe is wound on the outer wall of motor, coolant is flowed through in cooling water pipe, cooled to electric motor temperature reduction by coolant, the import of cooling water pipe is arranged at one end of motor, outlet is arranged at the other end of motor, the whole axial length of motor is all distributed with cooling water pipe, and cooling water pipe is along the circumferential curl distribution of motor, cooling water pipe can cover the periphery of motor completely, the contact area of this spiral helicine cooling water pipe and motor outer wall is larger, the cooling effectiveness of motor can be improved, and cooling water pipe has covering on whole motor surface, cooling evenly.
The present invention also provides a kind of electric motor car, and this electric motor car comprises any one motor above-mentioned.Because above-mentioned motor has above-mentioned technique effect, the electric motor car with this motor also should have corresponding technique effect.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The structural representation of the motor that Fig. 1 provides for embodiment a kind of in the present invention.
In accompanying drawing, mark is as follows:
1-motor, 2-cooling water pipe.
Embodiment
Core of the present invention is to provide a kind of motor, effectively improves the cooling effectiveness of motor; Another core of the present invention is to provide a kind of electric motor car comprising above-mentioned motor.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, the structural representation of the motor that Fig. 1 provides for embodiment a kind of in the present invention.
In a kind of embodiment, the motor of electric motor car provided by the present invention, comprises motor 1 and cooling water pipe 2, and motor 1 is motor 1 common on the market, and the model of motor 1 can be determined according to the difference of concrete service condition.Cooling water pipe 2 is wound on the outer wall of motor 1, and cooling water pipe 2 can be flexible pipe, can be wrapped on motor 1.Flow through coolant in cooling water pipe 2, cooled by coolant to motor 1, the import of cooling water pipe 2 is arranged at one end of motor 1, and outlet is arranged at the other end of motor 1, and the whole axial length of motor 1 is all distributed with cooling water pipe 2.Cooling water pipe 2 is along the circumferential curl distribution of motor 1, be specially shape of threads distribution, the quantity of cooling water pipe 2 can be one, and in order to increase cooling effect further, cooling water pipe 2 also can be many, can arrange voluntarily according to actual service condition, cooling water pipe 2 can cover the periphery of motor 1 completely, and this spiral helicine cooling water pipe 2 is comparatively large with the contact area of motor 1 outer wall, can improve the cooling effectiveness of motor 1, and cooling water pipe 2 has covering on whole motor 1 surface, cooling evenly.
The motor of above-mentioned electric motor car is only a kind of preferred version, specifically be not limited thereto, can make pointed adjustment according to actual needs on this basis, thus obtain different execution modes, the helix tube of cooling water pipe 2 is uniformly distributed from one end of motor 1 to the other end.The whole axial direction of motor 1 is all provided with spiral helicine cooling water pipe 2, and the pitch between two adjacent rings helix tube does not do further restriction, can not be too intensive, too intensive waste cooling water pipe 2, increases the heavy burden of motor 1; Can not be too sparse, too sparse cooling effect does not reach, and can not lower the temperature to well motor 1.Adjacent helix tube can be uniformly distributed, also can uneven distribution, and concrete density situation and distribution situation, can determine according to actual service condition.
On the basis of above-mentioned embodiment, those skilled in the art according to the difference of concrete occasion, can carry out some changes to the motor of electric motor car.Coolant is flowed in cooling water pipe 2 by drive unit.Coolant circulates, coolant flows into from inlet under the effect of drive unit, flow out from liquid outlet, drive unit can be hydraulic pump, do work to cooling water pipe 2, make to produce pressure differential in cooling water pipe 2, drive coolant flowing, coolant constantly circulates, and strengthens the effect of its cooling motor 1.
Obviously, under the guidance of this thought, those skilled in the art can carry out some changes according to the difference of concrete occasion to the coolant in above-mentioned embodiment.Coolant is specially cooling water, and drive unit is specially water pump.Cooling water wide material sources, pollution-free, be used widely, coolant is cooling water, then drive unit is water pump, and certainly, coolant is other coolant, and drive unit can be the corresponding pump housing.
It is important to note that the motor of electric motor car provided by the present invention should not be restricted to this kind of situation.Water pump and motor 1 are connected to same controller.Water pump and motor 1 are connected to same controller, form closed circuit control, and feedback speed is fast, controls sensitiveer, are easy to control.Certainly, water pump and motor 1 can be not attached to same controller, can separate and independently control, and because mode in the cards is more, just illustrate no longer one by one here.
Based on the motor provided in above-described embodiment, present invention also offers a kind of electric motor car, this electric motor car comprises any one motor in above-described embodiment.The motor in above-described embodiment is have employed, so the beneficial effect of this electric motor car please refer to above-described embodiment due to this electric motor car.
