Embodiment
With reference to figure 1, the shell of the integrated morphology 100 of driving governor and direct current transducer mainly comprises upper cover plate 110, driving governor housing 140, direct current converter casing 150 and lower cover 170, internal component mainly comprises thin-film capacitor 120, IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) module 130 and DC conversion modules 160.In driving governor housing 140, be provided with and comprise thin-film capacitor 120, IGBT module 130 and the unmarked drive control module such as drive plate, control board illustrating, and seal with upper cover plate 110.DC conversion modules 160 is installed in direct current converter casing 150, and seals with lower cover 170.Wherein, IGBT module 130 belongs to the heating module in driving governor, and DC conversion modules 160 also can produce higher heat in the course of the work, and they all need cooling, or also exists other the cooling components and parts of needs also can be regarded as heating module.In the present embodiment, together with direct current converter casing 150 arrives by screw fastening in vertical direction with driving governor housing 140, make like this direct current transducer and driving governor be disposed in vertical space, and no longer need in horizontal space, be arranged in juxtaposition, this layout that is electric motor car has been brought higher flexibility.
In conjunction with Fig. 2, Fig. 3, driving governor housing 140 is formed around diapire 143 by sidewall 144, and as seen from Figure 1, is provided with outlet pipe 141 and water inlet pipe 142 on sidewall 144.From Fig. 2 and Fig. 3 visible be the upper surface 145 of diapire 143, upper surface 145 contacts with one or more in the drive control modules such as above-mentioned thin-film capacitor 120, IGBT module 130 and drive plate, control board.A not smooth surface of upper surface 145, on upper surface 145, the two ends with the base plate 148 of flute profile first water channel 146, the first water channels 146 of local dent formation have water inlet 147 and water return outlet 149.Visible in conjunction with Fig. 4, after drive control module is installed in driving governor housing 140, IGBT module 130 covers on the first water channel 146 just, thereby makes to form between IGBT module 130 and base plate 148 the coolant flow pipeline of a relative closure.Certainly, in order to improve sealing property and water isolating, IGBT module 130 belows can also increase sealing gasket, barrier film etc., and this also belongs to " contact ", the category of " covering " herein.Or, also the same easily thin-film capacitor 120 of heating can be covered on the first water channel 146.
With reference to figure 5.Fig. 5 is the approximately 180 ° of later views of driving governor housing 140 flip horizontals in Fig. 2, and what mainly show is the structure of the lower surface 1410 of diapire 143.Known in conjunction with Fig. 1, after having assembled, lower surface 1410 is and direct current converter casing 150 contact surfaces.Lower surface 1410 also and the surface of non-flat forms, but has flute profile the second water channel 1411, and after having assembled, direct current converter casing 150 covers on the second water channel 1411, thereby on lower surface 1410, forms the coolant flow pipeline of a relative closure.Certainly, in order to improve sealing property and water isolating, also can increase sealing gasket, barrier film etc. between direct current converter casing 150 and lower surface 1410, this also belongs to " contact ", the category of " covering " herein.Be separated into multiple points of flowing flux at the second water channel 1411 by multiple partition walls 1412, water inlet openings 1414 positions between adjacent partition wall 1412 are provided with boss 1413.Boss 1413 does not seal water inlet openings 1414, but has with it certain distance.The effect of partition wall 1412 and boss 1413 will be described hereinafter.
Visible in conjunction with Fig. 2, Fig. 3 and Fig. 5, the water inlet 147 of the first water channel 146 and water return outlet 149 are communicated with the second water channel 1411.Like this, on the upper surface 145 of diapire 143 and lower surface 1410, formed Double-layer drain, and in the position of base plate 148, the first water channel 146 and the second water channel 1411 are overlapping.
With reference to figure 6, in this figure to represent the flow direction of cooling fluid with the line of arrow.Cooling fluid enters the second water channel 1411 from water inlet pipe 142, in the second water channel 1411, flow after a segment distance, enter in whole or in part the first water channel 146 at water inlet 147 places, cooling fluid in the first water channel 146 is back to the second water channel 1411 via water return outlet 149 again, after the moving segment distance of the second water channel 1411 relaying afterflows, is flowed out by outlet pipe 141.When cooling fluid flows in the second water channel 1411, can be separated wall 1412 and shunt, this has improved radiating effect.Boss 1413 not only can be used for the installation of trip bolt, and its setting position makes cooling fluid before entering opening 1414, between boss 1413, partition wall 1412, form turbulent region, the water layer of pressing close to direct current transducer and heat exchange having occurred in such the second water channel 1411 can mix with the water layer that heat exchange does not also fully occur away from direct current transducer, improves the cooling effect of cooling fluid in subsequent flowing process.Known in conjunction with Fig. 1, Fig. 6, the second water channel 1411 of S shape provides large-area cooling for the DC conversion modules 160 in direct current converter casing 150, has guaranteed the good cooling effect of DC conversion modules 160.And from whole cooling fluid stream, cooling fluid in the second water channel 1411 enters after the first water channel 146 via water inlet 147, in base plate 148 positions, cooling fluid is to flow along the direction contrary with coolant flow direction in the second water channel 1411, that is to say, cooling fluid first along a direction (as shown in band arrow heavy line) flow to DC conversion modules 160 carry out one section cooling after, the first water channel 146 that enters upper strata at base plate 148 places flows and carries out cooling to IGBT module along contrary direction (as shown in band arrow thick dashed line), and then get back to the second water channel 1411 and continue to carry out cooling along former direction to DC conversion modules 160, this has extended the flow path of cooling fluid, make cooling fluid to carry out fully cooling to the cooling components and parts of needs, improve cooling effect.And the first water channel 146, the second water channel 1411 are to be formed in driving governor housing 140, without exterior line, driving governor and direct current transducer are connected, integrated level, cooling effect are all improved.
Together with driving governor housing 140 arrives by screw fastening with direct current converter casing 150 in the present embodiment, the advantage of doing is like this to be convenient to the formation of the first water channel 146 on the upper surface 145 of diapire 143 and the second water channel 1411 on lower surface 1410, but together with the present invention does not get rid of driving governor housing 140 is fastened to by integrated mode with direct current converter casing 150, certainly do like this and can make production technology more complicated.
Although the present invention is described in conjunction with above embodiment, the present invention is not limited to above-described embodiment.Those of ordinary skill in the art can easily modify to it and change, but do not leave essence design of the present invention and scope.
