Embodiment
Fig. 1 illustrates according to power electronic system 1 of the present utility model with 3-D view.In the case, the housing 2 of power electronic system is shown roughly, this housing has frame type housing parts 20, and this housing parts has a plurality of openings, and these openings are by two differently impression cap 3,4 sealings out.
In addition, housing 2 has a plurality of interface arrangements 22 on its frame type housing parts 20.At this, only arrange total interface device 22 on a housing side.These interface arrangements 22 are for example to be used for connecting the load current interface 220 of electro-motor or energy accumulator here, are used for controlling the control interface 222 of power electronic system and the inner colded coolant interface 224 that is used for this power electronic system.
Fig. 2 illustrates power electronic system 1 of the present utility model according to the foundation of Fig. 1 in the situation that open the partial view of the first cap 3 with 3-D view.Ground, below, unshowned the first cap of next-door neighbour are furnished with capacitor device 6, and this capacitor device 6 is hidden by the first cap 3 referring to Fig. 1.
Capacitor device 6 is comprised of a plurality of single similar capacitors 60, and they are arranged in two-dimensional matrix.In this arrangement, the capacitor 60 that some capacitors 60 are relatively adjacent arranges in the mode that 90 degree reverse, and obtains thus intermediate space 62,64.At this, intermediate space 62,64 is not understood to be in the space between the capacitor 60 that almost is close to, and just has the space at the following interval of capacitor and capacitor, and this interval surpasses 1/5th of single capacitor extension.In the case, on the first intermediate space 62 side direction surrounding by capacitor 60 around, and can't help capacitor 60 boundaries but by housing 2 its inwall 208 boundaries in other words on the second intermediate space 64 side direction at least one side.
In principle between capacitor 60 and at capacitor 60 and housing 2 around them, be frame type housing parts 20 and unshowned the first cap 3 at this, between arbitrary volume should use Embedding Material 620 embeddings.This Embedding Material 620 is particularly useful for capacitor 60 and discharges to the heat on housing 2.Arrange in order to save in the case Embedding Material 620, the recess 32,34 of the first cap 3 stretches into intermediate space, for this reason referring to Fig. 1 and Fig. 3.
The sealing surface 202 of frame type housing parts 20 be shown in addition and be used for layout referring to the space 206 of the jockey 308 of Fig. 1, being used for installing the first cap 3.
Fig. 3 illustrates the profile that passes according to the power electronic system 1 of Fig. 1.Frame type housing parts 20 are shown in the case and are arranged on interface arrangement 22 on a side of this housing parts 20.Power semiconductor modular 50, capacitor device 6 and other assemblies 7 of having constructed power electronic circuit equipment 5 are shown in the inside of housing 2.These other assemblies 7 can be control circuit plate, transducer, be used for buss bar member and cooling device that electric current distributes.
Especially can identify, capacitor device 6 is comprised of a plurality of similar capacitors 60, and these capacitors are at this, but not necessarily, is arranged on common circuit board.Capacitor device 6 by frame type housing parts 20 laterally around, wherein, these capacitors 60 protrude from the opening that is formed by this housing parts 20 slightly.
These capacitors 60 of capacitor device 6 are covered by the first cap 3, and this first cap has recess 32, two kinds of different designs of 34 here.
Can see in addition, the first recess 32 of the first cap 3 only stretches into the first intermediate space 62 by capacitor 60 boundaries, and the second recess 34 of the first cap 3 stretches in the second intermediate space 64 by capacitor 60 and 208 boundaries of the inwall in the fringe region of frame type housing 20.
By these recess 32,34, intermediate space 62 separately, volume 64, that should utilize Embedding Material 620 to fill obviously reduce, and have saved thus Embedding Material 620.Except discharging heat, Embedding Material 620 can be used for the damping to capacitor 60 motions, if these capacitors are because the external force to power electronic system 1 causes motion, the especially words of vibration.Because Embedding Material 620 typically is the gel structure, so excessive this motion of sufficiently damping of the volume that is associated.Because obviously reduced at the volume between capacitor 60 and housing 2 in other words between capacitor 60, so also obtained thus the obvious improvement of vibration damping by recess 32,34.
Fig. 4 illustrates the profile that passes the first cap 3 with 3-D view, and Fig. 5 illustrates this first cap 3 from the enclosure interior observation place.In the case, the first cap 3 has fringe region and flat site 36, and this flat site has been constructed smooth interarea.Be provided with sealing device 302 in the fringe region of cap, the sealing device is with corresponding referring to the sealing surface 202 of the frame type housing parts 20 of Fig. 2 and thus in the situation that mounted the first anti-tideland closure casing 2 of cap 3.For this reason, in edge region, this is outside equipped with the Connection Element 304 with space 306, and wherein, these spaces are corresponding with the space of attaching troops to a unit 206 referring to the housing 2 of Fig. 2.By being arranged in referring to the bolt 308 of Fig. 1 the moisture seal of mentioning that forms housing in these spaces.
First and second recess 32,34 of the first cap 3 are shown in the case equally.These two recess not only have bottom 320,340 at this, also have to a certain extent " auxiliary equipment " with respect to the interarea upper shed.This bottom 320,340 can be configured to smooth face, and these faces for example are transitioned in the fringe region of recess by seamed edge by rounding or in the simplest situation.Alternatively, bottom 320,340 also can be spherical ground almost be configured to the part face of ball or be configured to point.
Importantly, according to above-mentioned restriction, 320,340 to opening from the bottom in recess 32, all designs of 34, continuous or discontinuous the widening of recess.Only have and utilize this design to realize, accumulated in this recess 32,34 and be converted into subsequently the solid-state physics state, namely ice water almost expel from recess 32,34 in the case voluntarily.In brief and relate to and have the just circular recess ground of what a bottom, along from the bottom to opening direction, diameter does not allow in any position to reduce.
That this requirement is suitable for is same and shown here, respectively have bottom 320 more than one, 340 recess 32,34 adaptive, wherein, bottom 320 separately, 340 is by dividing plate 322,342 separated from one another.Usually these dividing plates 322,342 do not reach the opening of recess, thus, have some single part recess in the first area after bottom 320,340, and these single part recess are being fused into the part lead division on top in the distribution of opening.
This requirement is suitable for equally and does not have smooth interarea but have the first cap 3 adaptive of contoured face.
