Embodiment
1 pair of air-cooled electric motors of the present invention of following structure accompanying drawing and working method thereof further describe.
Accompanying drawing only is expressed as one of most preferred embodiment of the technical scheme that realizes that the object of the invention is taked, and technical scheme involved in the present invention may have similar some forms of expression, is not as the criterion with accompanying drawing uniquely.
As shown in Figure 1, gas cooled electrical machine casing 6 among the present invention is provided with air inlet 7 and air outlet 8, and position shown in the position of air inlet 7 and air outlet 8 is not limited only on the figure can be according to actual conditions, side near front and rear cover on casing 6 is provided with air inlet 7, and opposite side sets out air port 8.Be communicated with by connecting pipe in the motor outside between air inlet 7 and the air outlet 8, institute's connecting pipe is provided with radiating part 20.Air inlet 7 and air outlet 8 are communicated to respectively in the cavity between end cap and stator winding 4, rotor 3, the rotor field spider 21.During machine operation, because the heat that the heating of stator winding 4 produces can make the winding ambient air reach the high temperature of Baidu, the rotation of rotor 3 makes air generation disturbance in the motor, make high temperature air enter connecting pipe by air outlet 8, air in radiating part 20 heat radiation back coolings is got back to motor internal by air inlet 7, reaches the effect of motor radiating.Motor and connecting pipe, radiating part 20 form the circulation circuit of sealing, can guarantee that air-flow is unobstructed, and satisfy the requirement of motor seal.
As a kind of preferred mode, rotor 3 ends of gas cooled electrical machine are provided with blade 5, and at this moment, the position of the blade 5 on the motor rotor 3 is depended in the position of air inlet 7 and air outlet 8.Specifically, when blade 5 is in back end cover for motor 23 1 sides, it is position shown in Figure 1, air outlet 8 is positioned on the back end cover for motor 23 1 side casings, be communicated in back end cover for motor 23 and stator winding 4, rotor 3, the rotor field spider 21 formed cavitys, air inlet 7 is positioned on the motor front end housing 22 1 side casings, is communicated in motor front end housing 22 and stator winding 4, rotor 3, the rotor field spider 21 formed cavitys; When blade 5 is in motor front end housing 22 1 sides, air outlet 8 is arranged on the casing 6 of motor front end housing 22 1 sides, be communicated in front end housing 22 and stator winding 4, rotor 3, the rotor field spider 21 formed cavitys, air inlet 7 is arranged on the back end cover for motor 23 1 side casings 6, is communicated in rear end cap 23 and stator winding 4, rotor 3, the rotor field spider 21 formed cavitys.The effect of blade 5 is, by air-flow in the blade 5 disturbance motor casings 6, produces pressure difference in the space that motor front and rear cover and rotor 3, stator winding 4 are formed when rotor 3 rotates, and air flows by rotor field spider 21 thread emptying apertures, forms air-flow at motor internal.On the one hand, an end that has rotor blade 5 in the motor forms relatively high pressure, and high temperature air is pushed in the connecting pipe by air outlet 8, dispels the heat at radiating part 20; On the other hand, the vaneless end of rotor is because the mobile formation relatively low pressure of air is inhaled into motor internal through radiating part 20 cooled air by connecting pipe, thereby the circulation of formation air is strengthened radiating effect, shown in arrow among Fig. 1.
In order to strengthen radiating effect, can blower fan 15 be installed on connecting pipe, make the interior air flows of motor faster, further strengthen radiating effect.In addition, mounted valve 16 on connecting pipe, and by opening or closure of control device by-pass valve control 16, thereby whether the control air flows, and can increase the flexibility of controlling of heat abstractor.
Be arranged at radiating part 20 on the connecting pipe described in the present invention, be meant the mechanism that is used to reduce air themperature in the pipeline of setting, can play the mechanism of similar effect as the particular design of fan, refrigerant or pipeline itself and other.Can be the said mechanism that is arranged on the whole connecting pipe, also can be arranged on wherein a section in the whole pipe.
Air inlet 7 described in the present invention and air outlet 8 can be one or more, but have an air outlet and an air inlet at least.When air inlet and air outlet can have many connecting pipes when being a plurality of.
In addition, also will introduce a kind of device that utilizes motor gas heat that battery pack is heated in this specification, with power battery pack as the top radiating part of mentioning.Below in conjunction with accompanying drawing 2 this device is described.
Power battery pack 10 is outside equipped with battery railway carriage or compartment 11, offer heating air inlet hole 12 and heating venthole 13 on the described battery railway carriage or compartment 11, described connecting pipe is divided into intake stack 14 and wind pipe 9 two parts, wherein be arranged at the air outlet on the motor case 6 and be arranged between heating air inlet 12 holes on the battery railway carriage or compartment wind pipe is set, be arranged at the air inlet 8 on the motor case and be arranged between the heating venthole 13 on the battery railway carriage or compartment 11 and be provided with intake stack.
In order to reach the purpose to battery heating of the present invention, described wind pipe 9 is provided with attemperator, with the heat of the gas that keeps discharging in motor cavity.On the wind pipe 9 blower fan 15 can also be set,, strengthen the battery efficiency of heating surface to increase the speed of air-flow.Being provided with of valve 16 can determine whether battery is heated as required, and be lower such as battery temperature, in the time of need heating battery, valve 16 should be opened; Battery temperature is suitable or higher, when not needing battery heated, valve 16 can be closed.
The hot gas of discharging from motor internal enters the battery railway carriage or compartment by wind pipe 9, because battery pack 10 leaves certain space between each battery unit when linking, so hot-air can enter battery pack from the space between each battery unit, battery pack is evenly heated, than using liquid container heating and phase-change material more economically with efficient.Certainly, the present invention also can use uniformly the pipe arrangement of being made by thermal conducting material between each battery unit, perhaps is arranged in the battery railway carriage or compartment thermal air current piping, thereby the heating battery unit, but this mode is more on the low side than the direct contact battery unit of hot-air efficient.
Process and battery exchange heat, cooled air is got back to motor internal by intake stack, forms circulation, and in cooling motor, heating battery makes energy utilization efficiency higher.
