Abstract
The invention relates to a fanless motor cooling structure. A plurality of inclined axial ventilation holes are formed in a rotor, a water sleeve is sleeved outside a stator, and a wind sleeve is sleeved outside the water sleeve. The water sleeve is of an annular or S-shaped structure, and a water inlet and a water outlet are arranged on the water sleeve; a cooling sheet is arranged in the wind sleeve and is connected with the outer wall of the water sleeve in a matching manner; and the inner wall of the water sleeve is connected with a motor stator in the matching manner. When running at a high speed, a fanless structure not only reduces noise and vibration, but also improves reliability of a machine structure, thereby being very suitable for the field of a high-speed motor; and by utilizing a loop of a wind path, and the fanless motor cooling structure can enlarge a double cooling contact area by matching with the conventional water sleeve cooling structure, so that the ventilation cooling effect is greatly improved. The fanless motor cooling structure disclosed by the invention replaces a fan by centrifugal force of a rotary rotor to provide internally circulated wind pressure so as to solve problems of the noise and the vibration due to the fan at the high speed; in addition, a wind sleeve structure is additionally arranged so as to provide an internal air circulation loop, enlarge the area of heat exchange and improve the cooling effect of the motor.
Description
Technical field
Patent of the present invention relates to a kind of motor cooling structure, especially a kind of cooling structure that is suitable for the high speed high power density motor.
Background technology
Motor adopts aerofoil fan or centrifugal fan to produce inner blast mostly at present, realizes inner coolant circulation; But when motor was high-speed electric expreess locomotive, the noise of fan, vibration and intensity became the bottleneck of high-speed electric expreess locomotive design.
The tradition settling mode is to adopt outside blower fan that blast is provided, but this will increase extra accessory motor and power supply unit, increase the complexity of system.
Summary of the invention
The present invention will provide a kind of motor cooling structure that does not have fan, is used in the cooling technology problem that solves high-speed electric expreess locomotive, and this structure has been cancelled traditional fan, and the centrifugal force that utilizes the rotor rotation to produce provides blast, realizes inner wind circulation.
For realizing above-mentioned purpose, technical scheme of the present invention is: a kind of motor cooling structure that does not have fan, comprise rotor, and stator is characterized in: have the axial ventilation hole of some inclinations in the rotor, the stator outside is with water jacket, and the water jacket outside is with the wind cover.
Water jacket is annular or S type structure, which is provided with entery and delivery port; Wind cover inside is provided with cooling fin, and cooling fin and water-jacket outer wall are connected; Water jacket inwall and motor stator are connected.
The invention has the beneficial effects as follows:
Rotor of the present invention has the axial ventilation hole of inclination, when rotor rotates, because the existence of centrifugal force; Can produce blast between two ends of rotor; The circulation of promotion inner air when air is flowed through stator end, can effectively be cooled off the end; Air passes through the wind cover of water jacket outside then, realizes the closed-loop path.Wherein: the wind cover has two effects:
(1) loop that provides inner air to circulate.
(2) can install air/water cooler additional in the wind cover, increase heat exchange area, thereby improve the cooling effect of motor.
Install water jacket additional between stator outside and the wind cover in addition, this water jacket is traditional jacket structure for water, and different is that air/water cooler and water jacket integrated design in the wind cover can shared cooling waters.
The present invention compares traditional fan structure and jacket structure for water, has the following advantages:
1) compare traditional motor shaft fan, no fan structure has not only reduced noise, vibration when high speed, improved the reliability of mechanical structure simultaneously, therefore is fit to very much the high-speed electric expreess locomotive field;
2) utilize the loop of wind path, cooperate traditional water jacket cooling structure, can increase the cooling contact area of twice, improved the ventilation cooling effect greatly.
Centrifugal force when the present invention adopts the rotor rotation replaces fan that the blast of inner loop is provided, and has solved noise and the vibration problem of descending fan to bring at a high speed; Increase this structure of wind cover in addition, when the inner air circulation circuit is provided, increased heat exchange area, improved the cooling effect of motor.
Description of drawings
Fig. 1 is a structure cutaway view of the present invention;
Fig. 2 is the left cutaway view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Like Fig. 1, shown in 2, the high efficiency motor cooling structure of no fan of the present invention comprises rotor 1, stator 7, water jacket 3, wind cover 5 etc.
When rotor 1 rotation, can produce blast at two ends, blast drives hot-air and flows through rotor ventilation hole 2; Through behind the stator end 6 cooling stator ends, get into stator wind cover 5 then, wind overlaps 5 inside and has cooling fin; Cooling fin is fixed on the shared wall; Can the heat of hot blast be passed on the wall through cooling fin, and then pass to the cooling water of water jacket 3 inside, a part of in addition heat spreads out of motor through the outer wall of wind cover 5.
In addition; In order better to increase cooling effect, install water jacket 3 additional between wind cover 5 and the stator 7, water jacket 3 inwalls cooperate with motor stator 7 direct hot jackets; The heat major part of stator core and stator winding is passed to water jacket 3 through stator 7 outer walls through heat conduction, through external refrigeration water heat is taken away then.
