Description
Technical field
The utility model relates to power modules layout in electric equipment, is specifically related to power modules structure in a kind of electric equipment.
Background technology
The power modules of existing high-power electronic device adopts plane figure usually.Each power model in electronic equipment is in order successively by the arrangement of " one " font, and it is comparatively large that this layout takies volume, and space availability ratio is low, and the more machine volumes of the power model in equipment are larger.The layout type of " one " font arrangement of power model makes the heat radiation of power model more difficult, in order to meet the cooling requirements of system, each power model needs to install one group of blower fan separately, independent heat radiation, so the heat radiation cost of complete machine is higher, and enough incoming air areas to be reserved between each cooling fan, thus cause power modules volume compared with large, fan trouble point is many, installation and maintenance are more complicated.
Summary of the invention
In order to overcome above-mentioned prior art Problems existing, the purpose of this utility model is to provide power modules structure in a kind of electric equipment, and whole power modules adopts stereoscopic arrangement, and module can left and right, up and down symmetric configuration, can enclosure interior be made full use of, reduce volume.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Power modules structure in a kind of electric equipment, comprise multiple power modules unit 1-1 ~ 1-N and capacitor bus-bar assembly 7, described multiple power modules unit 1-1 ~ 1-N is face-to-face symmetrical placed side by side and/or place up and down in the left and right of capacitor bus-bar assembly 7 according to its quantity, and described multiple power modules unit 1-1 ~ 1-N is connected with capacitor bus-bar assembly 7 by multiple switching busbar 8.
Described power modules unit 1-1 ~ 1-N comprises radiator 9, be fixed on the IGBT module 10 on radiator 9, the IGBT module be fixed on radiator 9 by insulated column exports switching copper bar 11, one end that IGBT module exports switching copper bar 11 is connected with the output of IGBT module 10, and the other end is kept and is connected with external module; Also comprise the mounting bracket 12 be fixed on radiator 9, mounting bracket 12 is for installing or the handle that serves as when removing this power modules unit for this power modules unit of pull; Described switching busbar 8 is fixed on radiator 9 by insulated column, and one end of switching busbar 8 is connected with the input of IGBT module 10, and the other end is connected with capacitor bus-bar assembly 7.
Compared to the prior art, tool has the following advantages the utility model:
(1) whole power modules adopts stereoscopic arrangement, and power modules unit can left and right, up and down symmetric configuration, can make full use of enclosure interior, reduce volume.
(2) power modules elemental area opposite is arranged on the surrounding of capacitor bus-bar assembly, and each power modules unit is vertically placed, often organize radiator all can before and after air-out, be independent of each other.Because each power modules unit is evenly distributed on interior of equipment cabinet, so interior of equipment cabinet even heat, interior of equipment cabinet can adopt a centrifugal blower to dispel the heat to each power modules.Therefore this topology layout makes that whole interior of equipment cabinet radiating efficiency is high, cost is low, volume is little, installation and maintenance are simple and convenient.
