Abstract
A kind of motor stator cooling structure, including a stator core (1), stator winding (3), also include a radiation shell (2), this radiation shell (2) wraps up stator core (1) and stator winding (3) in the circumferential, forming a heat dissipation channel (21), there is opening (23) at the axial two ends of described radiation shell (2).Heat dissipation channel constraint cold air can only be flowed by heat dissipation channel, and this guarantees the parts in radiation shell can sufficiently contact with cold air, it is ensured that each several part can sufficient pre-air contact, thus carry out heat exchange.
Description
Technical field
This utility model relates to a kind of cooling devcie of motor, is specifically related to a kind of due to the structure of stator cooling.
Background technology
The cold external environment natural cooling of substantially examining of existing motor, or the cooling of external force air intake.But there is air inlet when air intake cools down few with internal structure of motor contact surface, and air intake directivity is poor, a part of heat production point air flow rate is few, though cause can air inlet actual radiating efficiency the highest.
Summary of the invention
The purpose of this utility model is to provide one to retrain motor air intake direction, makes air-cooled motor stator cooling structure in hgher efficiency.
To achieve these goals, this utility model includes, stator core, a stator winding, also includes a radiation shell, and this radiation shell wraps up stator core and stator winding in the circumferential, forms a heat dissipation channel, and there is opening at the axial two ends of described radiation shell.
Heat dissipation channel constraint cold air can only be flowed by heat dissipation channel, and this guarantees the parts in radiation shell can sufficiently contact with cold air, it is ensured that each several part can sufficient pre-air contact, thus carry out heat exchange.
Further, there is equally distributed heat sink the side of described stator core, and described heat sink extends to the other end in one end axial from stator core, and heat sink spiral on stator core surface is arranged.
In order to improve cold air sky and stator each component contact probability further, the surface of stator core arranging heat sink, heat sink curl can be that flow spiral advances, and makes air fully be fully contacted with the various piece in circumference, thus improves heat exchange efficiency.
Preferably, the axial two ends of described radiation shell all have a cross section to be triangle or trapezoidal annular protrusion.Due to protruding existence, can turn to when air-flow passes through, rush at the tail end of stator winding.Owing to the generation of heat mostlys come from stator winding, radiating effect can be improved further by directly drying to stator winding.
Described radiation shell is that Heat Conduction Material is made, and Heat Conduction Material can absorb a part of heat, increases area of dissipation.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram.
Fig. 2 is heat sink schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
As shown in the figure, this utility model includes, a kind of motor stator cooling structure, including a stator core 1, stator winding 3, it is characterized in that, also include a radiation shell 2, this radiation shell 2 wraps up stator core 1 and stator winding 3 in the circumferential, forming a heat dissipation channel 21, there is opening 23 at the axial two ends of described radiation shell 2.
There is equally distributed heat sink 11 side of described stator core 1, and described heat sink 11 extends to the other end in one end axial from stator core 1, and heat sink 11 spiral on stator core 1 surface is arranged.
The axial two ends of described radiation shell 2 all have a cross section to be triangle or trapezoidal annular protrusion 22.
Described radiation shell 2 is made for Heat Conduction Material.
Heat dissipation channel constraint cold air can only be flowed by heat dissipation channel, and this guarantees the parts in radiation shell can sufficiently contact with cold air, it is ensured that each several part can sufficient pre-air contact, thus carry out heat exchange.In order to improve cold air sky and stator each component contact probability further, the surface of stator core arranging heat sink, heat sink curl can be that flow spiral advances, and makes air fully be fully contacted with the various piece in circumference, thus improves heat exchange efficiency.
