Description
Technical field
The utility model relates to a kind of inversion module that is used for high frequency switch power, particularly a kind of IGBT module of new structure layout.
Background technology
The high-power high-frequency switch power supply, more than the complete machine power output 10KW, its main power device IGBT module, caloric value is big.In order to reduce the working temperature of IGBT module, thus the reliability that improves its work with prolong the complete machine continuous working period, to IGBT module efficiently radiates heat; Seem particularly important; Under identical ventilation state, the IGBT module is carried out different layouts put design, can produce the different radiating effect.Conventional IGBT module is mounted in the both sides in air channel, and the assembling line is complicated; Or be installed in the top in air channel, and put with the wind, exist nearly air port cold again, the temperature uneven phenomenon of air port far away heat; For this reason, we adopt upper and lower layer air channel structure, and the IGBT module is installed in top, and beam wind is put; Therefore, the IGBT module is nearest apart from air inlet, and wind surface is even; Temperature is prone to balance, and actual measurement IGBT module temperature has reduced by 1/20, and continuous working period has increased by 1/6.Dwindled simultaneously complete machine front and back length more greatly, complete machine has dwindled 1/10, because the further improvement of complete machine ventilation effect, the heat radiation result of IGBT module is more effective.
The utility model content
The technical problem that the utility model will solve provides a kind of layout that is applicable to the high frequency switch power inversion module, specifically is a kind of IGBT module.
The primary structure characteristics of the utility model are: mainly by blower fan; Air switch, control transformer, IGBT module filtered electric capacity, control board, three-phase commutation bridge constitute, and an air switch, a control transformer are set under the blower fan, and an IGBT module 1 is set under its air switch; Its IGBT module connects a filter capacitor 11 time; One IGBT module 2 is set under its control transformer, and its IGBT module 2 times connects a filter capacitor 2, the common three-phase commutation bridge that is connected in below in its IGBT module 1 and the IGBT module 2; Its three-phase commutation bridge below is provided with a control board; Wherein air switch links to each other with three-phase commutation bridge, and control transformer links to each other with control board, and its IGBT module 1 is connected with control board with IGBT module 2.
The beneficial effect of the utility model is: the IGBT module is nearest apart from air inlet, and the air channel is short, and radiating condition is best, and wind surface is even; Temperature is prone to balance, and radiator reduces simultaneously, and production cost reduces, and reliability improves; Actual measurement IGBT module temperature has reduced by 1/20, and continuous working period has increased by 1/6, has dwindled complete machine front and back length simultaneously more greatly; Complete machine has dwindled 1/10, because the further improvement of complete machine ventilation effect, the heat radiation result of IGBT module is more effective.
