Abstract
The utility model discloses a kind of novel water inner cold motor cooling structure, including stator core, it is wound with stator coil on the stator core, is provided with cooling water pipe in the slot of the stator core.The utility model has the advantages that electric machine structure using this type of cooling is simple, good manufacturability, it is suitable for mass production.
Description
Technical field
The utility model relates to motor cooling technology, especially a kind of novel water inner cold motor cooling structure.
Background technique
Water-cooled machine is divided into shell water cooling and the cooling two kinds of types of cooling of internal water cooling at present.Shell water-cooled machine cools down water cooling
But motor housing, structure is simple, technology maturation, cooling effect are preferable.Water inner cold motor cooling water cools down electrical-coil, and structure is multiple
It is miscellaneous, technical requirements are very high, cooling effect can greatly improve the power-carrying of motor very well.It is multiple to solve water inner cold motor structure
Problem miscellaneous, technical requirements are high, proposes the present invention.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of cooling knot of novel water inner cold motor
Structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel water inner cold motor cooling structure, packet
Stator core is included, stator coil is wound on the stator core, is provided with cooling water pipe in the slot of the stator core.
Specifically, the cooling water pipe is snakelike shape.
Specifically, insulating layer is surrounded by outside the cooling water pipe.
Specifically, the cooling water pipe is rectangular copper pipe.
Specifically, the cooling water pipe is provided with multiple groups, and cooling water pipe one end is water inlet, and the other end is water outlet
Mouthful, the both ends of cooling water pipe through motor case and extend to outside it, and the inlet and outlet of multiple groups cooling water pipe pass through
Flexible insulated hose is connected in parallel.
The utility model have the advantage that (1) using this type of cooling electric machine structure is simple, good manufacturability, be suitble to
Batch production.
(2) good using the cooling effect of motor of this type of cooling, it is possible to reduce the volume of motor greatly improves the pole of motor
Limited capacity amount.
(3) it is separated using motor coolant liquid and the coil high-voltage electricity of this type of cooling, it is highly-safe.
(4) cooling water pipe is integrally formed, and without water pipe head in electric machine casing, stability maintainability is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the enlarged drawing in Fig. 1 at A；
Fig. 3 is the front view of cooling water pipe；
Fig. 4 is the side view of cooling water pipe；
In figure: 1- flexible insulated hose, 2- stator core, 3- cooling water pipe, 4- coolant liquid, 5- insulating layer, 6- stator coil, 7-
Water inlet, 8- water outlet.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to
It is as described below.
As shown in Fig. 1 ~ 4, a kind of novel water inner cold motor cooling structure, including stator core 2, cooling water pipe 3 are described
Stator coil 6 is wound on stator core 2, the cooling water pipe 3 is embedded in the slot of stator core 2, and cooling water pipe 3 is embedded in electricity
Machine stator iron core 2 is fitted closely with stator coil 6, and it is cooling to greatly improve motor for directly cooling stator coil 6 and stator core 2
Effect, improves motor power-carrying, and cooling water pipe 3 is integrally formed in motor case.
Further, the cooling water pipe 3 is snakelike shape.
Further, insulating layer 5 is surrounded by outside the cooling water pipe 3, cooling water pipe 3 and stator coil 6 are independently exhausted
Edge processing prevents high-voltage electricity in stator coil 6 from flowing into cooling system, guarantees the person and equipment safety.
Further, the cooling water pipe 3 is rectangular copper pipe.
Further, the cooling water pipe 3 is provided with multiple groups, and one group of cooling water pipe 3 is put in every pole, reduces to the greatest extent
The induced electromotive force of cooling water pipe 3,3 one end of cooling water pipe be water inlet 7, the other end be water outlet 8, the two of cooling water pipe 3
End is through motor case and extends to outside it, and the water inlet 7 and water outlet 8 of multiple groups cooling water pipe 3 are in parallel by flexible insulated hose 1
Connection, cooling water pipe 3 can induce electromotive force in stator core 2, cold if 3 conduction of cooling water pipe will generate closed loop
But will occur circulating current in water pipe, added losses can be lowered by increasing flexible insulated hose.
The utility model uses conductivity≤10 μ S/cm coolant liquid, prevents coolant liquid conductive, circulating current occurs, drops
Lower added loss.
The above, the only preferred embodiment of the utility model, not do limit in any form to the utility model
System.Anyone skilled in the art, in the case where not departing from technical solutions of the utility model ambit, all using above-mentioned
The technology contents make many possible changes and modifications to technical solutions of the utility model, or be revised as equivalent variations etc.
Imitate embodiment.Therefore, all contents without departing from technical solutions of the utility model, the technology according to the utility model is to the above reality
Any change modification, equivalent variations and modification that example is made are applied, the protection scope of the technical program is belonged to.
