electric power transformers with high power density on the dc / dc and dc / ac conversion

摘要

electric power transformers for arrangement on a rahmengstell with high power density on the dc / dc and dc / ac conversion, period: a housing (10).in accordance with the dimensions of the rahmengestells is establishedwith the housing (10) to its front page with a majority of lufteintrittsu00f6ffnungen (111) are provided and on its rear side with a majority of entlu00fcftungsu00f6ffnungen (121) eyeforms, and with a base plate (13) of the housing (10) below is trained; a belu00fcftungseinheit (20), on a side of the housing (10) is trainedso that the external cooling air by a majority of lufteintrittsu00f6ffnungen (111) in the housing (10) can be entered in the gehause (10) by a majority of the heattlu00fcftungsu00f6ffnungen (121) outwards leak, to be a umleitungsrichtung the process; a heat sink (30).in the housing (10) is trained and a majority of with a predetermined distance beabstandeten cooling fins (31) isthe one long side, and each with the umleitungsrichtung the process arranged parallel to each other; a majority of leistungselementen (40)what each with a wu00e4rmeableitungsflu00e4che (41) are provided and each of the wu00e4rmeableitungsflu00e4che (41) to the heat sink (30) arranged horizontally; and a leiterplattenmodul (50)the above ku00fchlku00f6rpers (30) arranged horizontally and with a majority of leistungselementen (40) electrically is connected; characteristicthe operation of the electric leistungswandlers of a majority of the leistungselementen (40) producing heat through a short cut to the cooling fins (31) of the ku00fchlku00f6rpers (30) u00fcbertstand,and that the external cooling air through the belu00fcftungseinheit (20) on the lufteintrittsu00f6ffnungen (111) in the housing (10) with cooling fins (31) of the ku00fchlku00f6rpers (30) can be introduced.the producing heat through the entlu00fcftungsu00f6ffnungen (121) of the housing (10) auszustru00f6men.
