| 发明名称 | Converter arrangement with an air cooling system | ||
| 摘要 | A converter arrangement includes a housing having a first cooling air channel, at least one capacitor disposed in the housing, a fan for generating a cooling air flow, and a first power electronics module disposed in the housing between the at least one capacitor and the fan, as viewed in a direction of the cooling air flow. The first power electronics module is positioned in relation to the fan so as to only be cooled by a first partial air flow. A second partial air flow provided for cooling the at least one capacitor is routed via the first cooling air channel past the first power electronics module such that the second partial air flow is thermally separated from the first power electronics module. | ||

| 主权项 | 1. A converter arrangement comprising: a housing having a first cooling air channel, at least one capacitor disposed in the housing, a fan for generating a cooling air flow, and a first power electronics module disposed in the housing between the at least one capacitor and the fan, as viewed in a direction of the cooling air flow, and being positioned in relation to the fan so as to be cooled only by a first partial air flow, wherein a second partial air flow provided for cooling the at least one capacitor is routed via the first cooling air channel past the first power electronics module such that the second partial air flow is substantially thermally separated from the first power electronics module, wherein the housing comprises a second cooling air channel, and wherein the first partial air flow is routed via the second cooling air channel past the at least one capacitor such that the first partial air flow is substantially thermally separated from the at least one capacitor. | ||
