Technical field
The present invention relates to power power domain.The present invention relates to a kind of electric power electronic module, concretely, is a kind of igbt (IGBT) power model.
Background technology
Take insulated gate bipolar transistor as main power model, in order to export larger power, need to be by multi-chip, not not mating due to each chip self parameter and circuit parameter when in parallel, occur that electric current distributes uneven problem when causing parallel connection, when serious, can cause device overload and damage, and in ceramic copper-clad plate (DBC) plate structure of planar power module midplane owing to being subject to the limitation of two-dimensional areas, on chip layout, be subject to many limitations.
In high power module, the parallel connection of a plurality of chips will produce very large heat, be necessary to carry out water cooler cooling, to guarantee their reliability service.Conventionally power model is planar structure, directly power model is arranged in cooled plate, has just utilized a face of cooled plate, in this planar power module, has the defect that one side radiating efficiency is lower.
Summary of the invention
The present invention is directed to traditional electric power electronic module multi-chip current-sharing design and the deficiency on radiating efficiency, ceramic copper-clad plate and the substrate of conventional I GBT module are optimized, have designed the novel six prismatic loop structures that comprise the ceramic layer of one side copper layer, six prismatic loop structures and the copper base of six prismatic loop structures.On six lateral surface copper layers of this six prismatic loop, place respectively igbt chip and power diode chip, by space symmetr, improved the harmony of parasitic parameter between each chip.
Deficiency in traditional electric power electronic module heat-sinking capability and in efficiency, combines it with six prismatic loop structures, the hollow region of this six prismatic loop, as the passage of water or other cooling fluids, improves the water-cooled efficiency of electric power electronic module integral body.
Technical scheme of the present invention is as follows:
The present invention is a kind of novel electric power electric module of three-dimensional structure.This novel plug adopts a kind of six prism space structures, and the hollow region of this six prismatic loop, as the passage of water or other cooling fluids, improves the water-cooled efficiency of electric power electronic module integral body.In each lateral surfaces of six prisms each layer of structure such as stacked chips symmetrically, by the bonding line of chip bottom copper sheet and chip surface, realize the parallel connection of each chip.At each face, placed the required power take-off of IGBT module, be connected with (9) with lead-out terminal (7), (8) on shell (11) simultaneously.
