Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). If the specific posture changes, the relative positional relationship, movement conditions, etc., the directional indication will also change accordingly, and the connection may ...

The invention discloses a high-power density motor. The high-power density motor comprises a rotor and a stator core, wherein the rotor is arranged in the stator core in a penetrating way, the rotor rotates in the stator core, a plurality of windings are arranged in the stator core, the stator core comprises cooling fins and two diversion devices, the cooling fins are arranged between adjacent windings, a through hole is formed in each cooling fin, penetrates through two ends and is used for guiding a refrigerant, the diversion devices sleeve the rotor, and the two diversion devices respectively sleeve top ends and bottom ends of the cooling fins and communicate with the through holes. In the high-power density motor, by additionally arranging the cooling fins and the diversion devices, the temperatures of the windings of the motor are reduced, the resistance generated by the windings due to heat generation is reduced, the currents of the windings are increased, so that the power density of the motor is improved; by additionally arranging an insulation layer, the current is prevented from flowing through the cooling fins to cause heat generation of the cooling fins, and moreover, short circuit is effectively prevented; and moreover, by additionally arranging a heat conduction layer, the heat of the windings is uniformly transferred to the cooling fins.
Description
technical field [0001] The invention relates to the field of motors, in particular to a motor with high power density. Background technique [0002] The existing technology generally adopts an aluminum shell with a circulating water channel outside the outer diameter of the iron core of the motor. In this way, the heat generated on the winding wire is transferred from the winding wire to the iron core of the stator core, and from the iron core to the aluminum shell. Then, the heat is taken out by the circulating water in the aluminum shell, the circulating water is connected to the radiator, and the water pump is used to circulate the water in the motor casing and the radiator, and the heat in the motor winding is dissipated to the outside air through the radiator middle. [0003] In the above heat dissipation method, the heat on the winding wire is transmitted to the shell through the iron core, and finally dissipated into the circulating water. Among them, the thermal con...
