Summary of the invention
The technical problem to be solved in the present invention is the radiating effect that increases former large power power electronic appliance under the condition that does not increase cost.
In order to solve the problems of the technologies described above, technical scheme of the present invention has provided a kind of layout structure of large power power electronic appliance, it is characterized in that: cavity and rear chamber before by first dividing plate inner space of large power power electronic appliance housing being divided into, preceding cavity is near the Qianmen of large power power electronic appliance housing, by second partition rear chamber is divided into first cavity and second cavity, the system unit unit, inductance unit and IGBT module group unit are arranged in preceding cavity, in first cavity and second cavity, wherein, the IGBT module group unit is positioned in the middle of the top of large power power electronic appliance housing, inductance unit is positioned at the bottom of large power power electronic appliance housing, system unit cooling fan and inductance unit cooling fan are arranged in preceding cavity and the rear chamber, system unit cooling fan and inductance unit cooling fan all are positioned at the top of large power power electronic appliance housing, middle part and bottom at the Qianmen have the Qianmen air inlet, position below the large power power electronic appliance housing is positioned at inductance unit has the bottom air inlet mouth, the cooling air heat that the air port enters the back or take away the system unit unit via the system unit heat dissipation wind channel that enters by the front door is discharged by the system unit cooling fan, discharge after perhaps taking away the heat of IGBT module group unit via IGBT module group unit heat dissipation wind channel, cooling air enters the heat of taking away inductance unit by the inductance unit heat dissipation wind channel by the bottom air inlet mouth and discharges by the inductance unit cooling fan.
Preferably, described IGBT module group unit comprises A phase IGBT module group unit, B phase IGBT module group unit and the C phase IGBT module group unit that is arranged side by side, be respectively equipped with A phase cooling fan, B phase cooling fan and C phase cooling fan under A phase IGBT module group unit, B phase IGBT module group unit and C phase IGBT module group unit, A phase cooling fan, C phase cooling fan are pressed opposite to layout with B phase cooling fan at fore-and-aft direction.
Advantage of the present invention is:
1, isolates separate cavity and air channel, improved radiating efficiency.
2, the raising of radiating efficiency selects for use the small-power fan to reduce system noise.
3, the heat radiation of IGBT module group unit can reduce bringing into of dust from middle and upper part, the Qianmen air intake of machine, has played good proofing dust and protecting effect.
4, IGBT module blower fan is taked the blowing mode, and what enter blower fan is cold wind, and the useful life of blower fan is longer.
5, IGBT module blower fan both guaranteed air intake by preventing phase mutual interference between the blower fan towards arranging on the contrary, had saved arrangement space again, made entire equipment overall dimension less, and interior layout is succinct, and is attractive in appearance, saved cost, and convenient the installation safeguarded.
