Embodiment
In order to understand the utility model in depth, below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
See accompanying drawing 1, the cooling air duct of the synchronous motor system that the utility model provides, comprising: exciter 1, first shell 10, air channel 4, main air duct 3, first air channel 2, second, water cooler 5, fan blade 6, synchronous machine and second housing 9; Synchronous machine is arranged on the centre position in second housing 9; Exciter 1 is arranged on the centre position in the first shell 10; Exciter 1 shares an armature spindle with synchronous machine; The bottom of second housing 9 is communicated with one end of main air duct 3; The one end in the first air channel 2 and the other end of main air duct 3 are axially docked and connected; The other end in the first air channel 2 is communicated with the bottom of first shell 10 one end; First air channel 2 is away from second housing 9; The one end in the second air channel 2 is communicated with at the top of main air duct 3 circumference; The other end in the second air channel 4 is communicated with the bottom of first shell 10 other end; Second air channel 4, near second housing 9, makes the hot-air of backflow in main air duct 3 more easily enter second housing 9 like this, whole cooling air duct is circulated more smooth and easy.First air channel 2 and main air duct 3 axially docks and the second air channel 4 to be communicated with at the top of main air duct 3 circumference and can the bottom of more convenient main air duct 3 to circulate cooling-air, and circulate hot-air on top, makes the gas flow in main air duct 3 smooth and easy more gently.When synchronous motor system operates, under the effect of fan blade 6, hot-air is blown to the rotor 8 of synchronous machine, then flows to the stator 7 of synchronous machine upward, finally enters water cooler 5 and cools, and forms a cooling circuit; Because the density of the density ratio hot-air of cold air is large, flow downward so be cooled directly with water the cooled cold air of device 5, stator 7 the latter half of synchronous machine is cooled, have part cold air to enter into the first shell 10 pairs of exciters 1 by main air duct 3, first air channel 2 to cool, cooled hot-air is got back in the cooling circuit of second housing 9 by the second air channel 4, main air duct 3 simultaneously.Because the first shell 10 of exciter 1 and the second housing 9 of synchronous machine are only be connected by main air duct 3, first air channel 2 and the second air channel 4, but not exciter 1 of the prior art and synchronous machine are in same shell, so avoid influencing each other of synchronous machine cooling air duct and exciter 1 cooling air duct, make respective cooling air duct more stable, do not occur the phenomenon of temperature field confusion, cooling effect is better.
Fan blade 6 and water cooler 5 are arranged in second housing 9, because the caloric value of exciter 1 is far smaller than the caloric value of synchronous machine, so fan blade 6 need are arranged on the armature spindle of synchronous machine, when synchronous motor system runs, cooling-air mainly cools the stator 7 of synchronous machine and rotor 8, part cold air is by main air duct 3, first air channel 2 flows into the first shell 10 pairs of exciters 1 and cools, cooled hot-air is again by the second air channel 4, main air duct 3 flows back to second housing 9 and forms cooling circuit, such design can ensure the cooling effect of exciter 1, do not increase again the cooling body of exciter 1, effectively control equipment cost.
Wherein, two fan blade 6 are set on the armature spindle of synchronous machine; Two fan blade 6 are connected in rotor 8 two ends of synchronous machine respectively; Fan blade 6 follows rotor 8 synchronous rotary.Two water coolers 5 are separately positioned on symmetrical position, second housing 9 top; Water cooler 5 is positioned at above the stator 7 of synchronous machine.When synchronous motor system runs, the rotor 8 that fan blade 6 follows synchronous machine rotates together, the rotor 8 of air flow synchronous machine, the middle part of synchronous machine the first half stator 7, and upwards cooled by water cooler 5, because cold air density is large, cooled air flows down, again through fan blade 6, and then forms cooling circuit at the upper space of second housing 9.Simultaneously, under the drive that the cooling-air produced by water cooler 5 rotates at the rotor 8 of Action of Gravity Field and synchronous machine, part cooling-air flows to the latter half of second housing 9, under the effect of fan blade 6, cooling-air flows to the rotor 8 of synchronous machine and the middle part of synchronous machine the latter half stator 7, and then forms cooling circuit in the lower space of second housing 9.Arrange fan blade 6 and water cooler 5 in the manner described above, make the air flow field of second housing 9 inside more stable simple, be beneficial to the calculating of wind path, then suitable cooling air delivery is determined, the cooling of synchronous machine inside can be ensured, gas current friction loss can be reduced again, improve electric efficiency.
The cooling air duct of a kind of synchronous motor system that the utility model provides is by being arranged in second housing 9 by synchronous machine, exciter 1 is arranged in the first shell 10, the cooling air duct of exciter 1 in the cooling air duct of second housing 9 inner synchronous machine and the first shell 10 is separated, make respective cooling air duct more stable, there will not be the phenomenon of temperature field confusion, be more conducive to the cooling air quantity calculating synchronous machine by conventional fluid mechanics theory exactly.By main air duct 3, first air channel 2 and the second air channel 4, first shell 10 is communicated with second housing 9, make the part cold air produced in second housing 9 flow into the first shell 10 pairs of exciters 1 by main air duct 3 and the first air channel 2 to cool, cooled hot-air flows back to second housing 9 by the second air channel 4 and main air duct 3 again and forms loop, such design can ensure the cooling effect of exciter 1, do not increase again the cooling device of exciter 1, effectively control equipment cost.By reasonable Arrangement fan blade 6 and water cooler 5, make the air flow field of second housing 9 inside more stable simple, be beneficial to the calculating of wind path, then suitable cooling air delivery is determined, the cooling of synchronous machine inside can be ensured, gas current friction loss can be reduced again, improve electric efficiency.
Above-described embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only embodiment of the present utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
