Embodiment

Below in conjunction with drawings and Examples, the utility model is described in more detail.

The utility model discloses a kind of power cell structure, in conjunction with shown in Fig. 1 to Fig. 4, described power cell structure includes casing, be provided with electrochemical capacitor 6 in described casing, rectifier bridge 7, IGBT module 8, copper bar 9, power panel 10 and driving control board 11, described casing includes panel 1, right plate 2, left plate 3, base plate 4 and upper cover plate 14, the setting adjacent with right plate 2 of described electrochemical capacitor 6, described rectifier bridge 7IGBT module 8 and the setting adjacent with left plate 2 of driving control board 11, the setting adjacent with back shroud 15 of described power panel 10, and this power panel 10 is perpendicular to base plate 4.Wherein, due to power panel 10, perpendicular to base plate 4, so, without taking larger liner plate area, not only simplified mounting process, also shortened air channel length, when the heat radiation air is blown within casing, can have reduced windage, thereby obtain better radiating effect.

In order to realize being fixedly connected with between power panel 10 and casing, this power cell structure also includes power supply supporting bracket 16, within described power panel 10 is fixed in casing by this power supply supporting bracket 16.

On this basis, the cover plate that the upper cover plate 14 of this power cell is the PC material, based on its insulation property, distance between each building block of upper cover plate 14 and box house is reduced, make this casing compare the casing that existing integral body is steel plate materials, further reduce overall dimensions, and saved product cost.

In the present embodiment, offer radiator window 12 on described panel 1, the heat radiation air is via this radiator window 12 within entering casing, correspondingly, the length direction of IGBT module 8 extends along the flow direction of heat radiation air, and IGBT module 8 is vertical setting, and it can not only reduce windage, also with the heat radiation air, more heat exchange area is arranged, with order heat radiation air, take away more heats.

According to the caloric value size of each building block in casing, the lower contactor 5 of caloric value between electrochemical capacitor 6 and panel 1, similarly, the lower rectifier bridge 7 of caloric value between IGBT module 8 and panel 1, thereby realize the hierarchical radiating layout.

Because the volume of electrochemical capacitor 6 is larger, so will there be larger space in adjacent position with it, can be used for arranging rectifier bridge 7, IGBT module 8 in this space and drive control board 11, wherein drive control board 11 to be positioned at the top of rectifier bridge 7 and IGBT module 8 and realize stacked setting, make the layout of above-mentioned building block compacter, and can reduce further the volume of power cell.

In the prior art, the IGBT module is horizontally set mostly, in the electric connection process, after first a plurality of electrochemical capacitors being connected with copper bar, by the electrochemical capacitor that is positioned at both sides, drawn, then through repeatedly after bending, being connected to the IGBT module, the circuit of this connected mode is longer, and wastes more copper bar.In the present embodiment, in conjunction with shown in Fig. 1 to Fig. 3, IGBT module 8 is vertical setting, the quantity of electrochemical capacitor 6 is a plurality of, and IGBT module 8 is drawn and be connected to a plurality of electrochemical capacitors 6 by the electrochemical capacitor 6 that is positioned at centre position after being electrically connected by copper bar 9, the adjacent setting of electric connecting terminal of drawing port and IGBT module 8 of this electrochemical capacitor 6, thereby shorten the length of copper bar 9, not only can reduce the bending number of times of copper bar 9, can also save the cost that is electrically connected material.
