Abstract

The invention provides a full-closed type rotary motor, wherein the interior of a housing can be cooled at a high efficiency. The full-closed type rotary motor comprises a horizontal rotation shaft (11), a rotor (12), a stator (13), two air coolers (15) on the two sides of the upper part of the stator (13) to sandwich the central part of the stator (13) in the direction of a rotation axis, a housing (14) of a sealed structure, and an internal circulation fan (17) for circularly sending the air sucked into the housing towards the air coolers (15) and positioned above the two air coolers inside the housing (14). The air cooled by the two air coolers (15) decreases to the stator (13) and the rotor (12), and then rises from the central part of the stator (13). After that, the air is blown out towards the two air coolers (15) by the internal circulation fan (17), thus being circulated inside the housing (14).

Detailed description of the invention
Below, with reference to accompanying drawing, the embodiment of the fully closed type electric rotating machine that the present invention relates to is illustrated.At this, same or similar part is marked common label, omit repeat specification.
[the first embodiment]
Fig. 1 indicates that the schematic cross sectional views of the first embodiment of the fully closed type electric rotating machine that the present invention relates to.Example illustrated is fully closed type induction conductivity.
Rotating shaft 11 by two bearings (not shown) by can around horizontal direction rotating shaft rotation in the way of support.At rotating shaft 11 fixed rotor 12, stator 13 is set to surround outside the radial direction of rotor 12.
The housing 14 of closed structure of storage rotor 12 and stator 13 is set, the through housing 14 of rotating shaft 11 and extend.It is provided above two air coolers 15 at housing 14 inner stator 13.Two air coolers 15 are in the setting spaced at intervals of rotating shaft direction.Air cooler 15 includes heat pipe 16 respectively.Carrying Cooling Water in the export-oriented each heat pipe 16 of housing 14, in heat pipe 16, heated cooling water is discharged outside housing 14.
In housing 14, the two ends, rotating shaft direction above air cooler 15 are arranged around two inner loop Air Blast fans 17.Linking Air Blast fan motor 18 respectively at inner loop Air Blast fan 17, utilize the electric power provided from housing 14 to make Air Blast fan motor 18 rotate, thus inner loop Air Blast fan 17 rotates.Two inner loop Air Blast fans 17 can rotate around the rotating shaft with the rotating axis parallel of rotating shaft 11 respectively, makes the air of the near top in housing 14 be received along rotating shaft is in outward direction, downwards, namely to surrounding's blowout of the heat pipe 16 of air cooler 15.
Partition wall 21 is formed so that it is be separated out: arrive two decline air flow circuits 19 of both sides, rotating shaft direction of the rotating shaft direction central part sandwiching stator 13 respectively through the surrounding of the heat pipe 16 of two air coolers 15 from two inner loop Air Blast fans 17 in housing 14;And the ascending air stream 20 of formation is sandwiched by two decline air flow circuits 19.Ascending air stream 20 is the stream of two inner loop Air Blast fans 17 of top arrival of the rotating shaft direction central part from stator 13.
In structure described above, rotor 12 and stator 13 air heated, from the top of stator 13, rise in the ascending air stream 20 of rotating shaft direction central authorities being formed, arrive the near top in housing 14.Utilize two inner loop Air Blast fans 17, outside rotor shaft direction, drive the air of this high temperature, further, driven down after by inner loop Air Blast fan 17, decline in two decline air flow circuits 19.In Fig. 1, the flowing of the air being depicted with arrows in housing 14.The air declined in decline air flow circuit 19, is first cooled down by air cooler 15, and the air of low temperature provides to rotor 12 and stator 13 from both ends, rotating shaft direction.
According to present embodiment, air cooler 15 air of the low temperature cooled down, not via inner loop Air Blast fan 17, being provided directly to rotor 12 and stator 13, therefore cooling effectiveness is high.It addition, the circulation of the air in housing 14 is identical with the situation of free convection, inner loop Air Blast fan 17 produces to promote the effect of free convection.Accordingly, it is capable to the driving energy making inner loop Air Blast fan 17 is Min..

In this embodiment, the central authorities at the top in housing 14 arrange an inner loop Air Blast fan 17.Inner loop Air Blast fan 17 can rotate around the rotating shaft of vertical direction, utilizes Air Blast fan motor 18 to rotate.
Other structure is almost identical with the first embodiment.
In structure described above, the air heated by rotor 12 and stator 13, from the top of stator 13, rise in the ascending air stream 20 of rotating shaft direction central authorities being formed, arrive the top in housing 14.Utilize the inner loop Air Blast fan 17 of center of top being arranged in housing 14, outside rotating shaft direction and drive the air of this high temperature, decline two decline air flow circuits 19 in down.In Fig. 2, the flowing of the air being depicted with arrows in housing 14.The air declined in decline air flow circuit 19, is first cooled down by air cooler 15, and the air of low temperature provides to rotor 12 and stator 13 from both ends, rotating shaft direction.
According to present embodiment, the effect same with the first embodiment can be obtained.
