(structure of the stream of framework)
Next, the structure of the stream 135 of framework 13 is described.As previously mentioned, by using the casting of not shown core, in the inside of framework 13, formed stream 135.In Fig. 8 A～Fig. 8 D, with thick arrow, represent the flowing based on stream 135 of cooling fluid.
As shown in Figure 8 A, first the cooling fluid flowing into from inflow entrance 136 flows into the 1st 135a of stream portion of stream 135.The 1st 135a of stream portion is formed on the bottom of the 1st incorporating section 131, and interior week and the stator 12 of stream are opposed, and periphery is opposed with the winding commutation circuit 20 being accommodated in the 1st incorporating section 131.The 1st 135a of stream portion forms roughly U word shape, and in the 1st incorporating section 131, IGBT201 and 2 groups of diodes 202 are along the 1st 135a of stream portion configuration of U word shape.
Cooling fluid mobile in the 1st 135a of stream portion flows into the 2nd 135b of stream portion via interconnecting part 135c (with reference to Fig. 8 B and Figure 11 described later).As shown in Fig. 8 B～Fig. 8 D, the 2nd 135b of stream portion forms circuitously with the Z-shaped shape that is circumferentially around the mode of stator 12 along framework 13 along the circumferential direction.The flow path width of the 2nd 135b of stream portion and the degree of depth are roughly fixing, and it is roughly fixing to form flow path area.In addition, in it, week is opposed with stator 12.As shown in Fig. 8 D, the downstream of the 2nd 135b of stream portion is communicated with flow export 137, and cooling fluid mobile in the 2nd 135b of stream portion flows out from flow export 137.Like this, cooling fluid is mobile cooling winding commutation circuit 20 and stator 12 on one side in the 1st 135a of stream portion on one side, and the cooling stator 12 on one side that flows in the 2nd 135b of stream portion on one side.
The 1st 135a of stream portion and the 2nd 135b of stream portion that form stream 135 form as follows: flow path width is larger, and number of turns is fewer.In the present embodiment, as shown in Fig. 8 A～Fig. 8 D, form: in the situation that from direction, right, lower direction, left to all directions observe framework 13, the number of turns of stream 135 is 1 time in all directions.Thus, flow path resistance can be reduced, cooling effectiveness can be kept well.
In the formation of stream 135, use the core (not shown) of crumbling property of oneself, this core for example utilizes the cement of regulation that sand is joined together and is formed.This core is arranged in mold when cast frame 13, and when becoming high temperature due to being pressed into of motlten metal, this core self crumbles.The supporting part of core forms inflow entrance 136, flow export 137, has part 136a, 137a and a plurality of outlet 1361 with inflow entrance 136, shape that flow export 137 is suitable along stream 135, crumbles and becomes sand-like core and discharged from these openings.
And, in order to form flowing of above-mentioned cooling fluid, as shown in Fig. 8 D, at the left surface that is formed with the framework 13 of inflow entrance 136 and flow export 137, need between the 1st 135a of stream portion and the 2nd 135b of stream portion, not form interconnecting part 135c, make not to be communicated with between them.That is, according to forming in which side of the left and right of framework 13 configuration that inflow entrance 136 and flow export 137 decide the left and right of interconnecting part 135c.Therefore, in the present embodiment, prepare the 2 kind cores corresponding with the configuration of inflow entrance 136 and flow export 137 in advance, according to this configuration change core, thus, can in the situation that not changing mold, form the stream 135 of the configuration that is suitable for having determined.
Next, utilize Fig. 9～Figure 11 to describe the details of the shape of the 1st 135a of stream portion.As shown in Figure 10 and Figure 11, the periphery 1351 (outside) of the 1st 135a of stream portion forms with winding commutation circuit 20 opposed plane, and interior all 1352 (inner sides) form cylindric, and interior at least a portion of all 1352 and stator 12 are opposed.Near aforesaid section P, plane periphery 1351 and cylindraceous interior all 1352 just more approaching, they are the most approaching near section P.Therefore, the 1st 135a of stream portion becomes such shape: the degree of depth of stream is the most shallow near section P, and near the left and right end portions of framework 13, the degree of depth of stream just increases.And interior all 1352 of the 1st 135a of stream portion must be not necessarily cylindric, for example also can form gently tilt towards the left and right sides from section P plane downwards.
In addition, as shown in Figure 9, the 1st 135a of stream portion forms in periphery 1351 and interior all 1352 and immediately approaches position, be section P near the roughly U word shape of bending.And the flow path width W of the 1st 135a of stream portion (flow path width of observing from top) forms along with become large near section P, and near bending part section P becomes maximum Wmax (> W).This be because: for the 1st 135a of stream portion, textural at it, near section P, stream dwindles on depth direction, therefore, near section P, just increase flow path width W, and near section P, make flow path width maximum, can make thus the flow path area of the 1st 135a of stream portion roughly fixing, thereby can suppress the increase of flow path resistance.
Interconnecting part 135c is communicated with the 1st 135a of stream portion and the 2nd 135b of stream portion at the rear of framework 13.As shown in figure 11, interconnecting part 135c forms to be become in it and the periphery of stator 12 such cylindric of concentric circle roughly in week 1353, and, near the right part of framework 13, the bottom of interconnecting part 135c just more tilts, and the degree of depth of stream increases.Consequently, can make towards the mobile of the 2nd 135b of stream portion, to become level and smooth from the 1st 135a of stream portion, there is the effect that can improve cooling effectiveness.
