Technical Field
The utility model relates to a disk motor indicates a disk motor with novel cooling system especially.
Background
With the breakthrough of new materials and new processes, the disk motor has smaller volume and lighter weight, so the disk motor is particularly suitable for occasions with strict requirements on the volume and the weight of the motor.

The existing disc type motor oil cooling system has the following defects: 1. the cooling effect is poor; 2. the cooling system has low working reliability, and once the oil pump fails, the cooling system fails; 3. the maintenance is inconvenient.
Therefore, how to optimize the cooling system of the disc motor is a problem to be solved by those skilled in the art.
Disclosure of Invention
In view of the above, it is an object of the present invention to provide a disc motor with a novel cooling system.
In order to achieve the above purpose, the utility model adopts the following technical scheme: an improved disc type motor comprises a shell, a stator, a rotor, an output shaft and a cooling system, wherein the stator, the rotor, the output shaft and the cooling system are arranged in the shell; the stator is wound with a hollow stator winding coil; the cooling system comprises condenser fins fixed outside the shell and an outer circulating pipeline passing through the condenser fins; the external circulation pipeline is communicated with the hollow stator winding coil, a one-way valve is additionally arranged between the external circulation pipeline and the hollow stator winding coil, and a refrigerant is filled in the pipeline.
Preferably, the refrigerant is anhydrous glycol.
Preferably, fan blades for accelerating heat exchange between the condenser fins and a refrigerant in the external circulation pipeline are arranged on the output shaft of the disc motor.
The utility model has the advantages that: 1. the cooling circulation system does not need power when working, and the cost is greatly reduced. Because power devices such as an oil pump and the like in a traditional oil cooling system are omitted, the whole disc type motor can save energy by more than 20%. 2. The structure is compact, the weight is small, and the weight is only 1/4 of the weight of the traditional oil cooling system. 3. The installation and the maintenance are convenient. 4. Stable performance and reliable operation. 5. The heat dissipation effect is good.

The external circulation pipeline 3 and the hollow stator winding coil 1 are filled with a refrigerant.
When the disc type motor operates, the temperature in the shell rises due to the high-speed rotation of the stator and the rotor, the refrigerant in the hollow stator winding is heated, expanded and vaporized, the vaporized refrigerant can only flow towards one direction due to the action of the one-way valve and flows to the external circulation pipeline 3 outside the shell, heat is taken away, the refrigerant exchanges heat with the condenser fins 2 after reaching the external circulation pipeline outside the shell, and the refrigerant is liquefied into liquid; and due to the unidirectional flow of the refrigerant, the cooled refrigerant enters the stator winding of the hollow core in the motor, and the refrigerant circulates in a reciprocating manner to realize the cooling of the disc motor.
For accelerating the cooling effect, as shown in fig. 1, the utility model discloses be equipped with flabellum 6 on disk motor output shaft 5, accelerate the flow of the outer condenser fin 2 surrounding air of casing, accelerate the heat exchange of the refrigerant in condenser fin and the extrinsic cycle pipeline. In an embodiment of the present invention, the coolant is anhydrous glycol.
In the embodiment of the present invention, the condenser fins 2 are fixed outside the motor casing by bolts. The fan blades 6 are integrally formed with the output shaft 5 of the disc motor.
Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
