Abstract
An apparatus having at least one membrane filter for a superficial filtering of at least dirt particles from inflowing cooling air for cooling an electrical module and also at least one cooling device for establishing an air flow in the housing and for discharging the heated-up cooling air out of the housing from at least one air outlet, the membrane filter having a netting of an electrically conductive material for electromagnetically shielding the electrical module.
Claims11
An apparatus for cooling an electrical module, comprising:
- a housing, wherein the electrical module is positioned inside the housing;
- at least one membrane filter positioned in an air inlet of the housing, the membrane filter providing filtering of at least dirt particles from inflowing air for cooling the electrical module, the membrane filter being formed of a fine-pored membrane which is made of electrically conductive material for providing electromagnetic shielding of the electrical module, and being applied to a coarsely woven backing material;
- and
- at least one cooling device for establishing an airflow in the housing and for discharging filtered cooling air, which is heated up upon flowing through and around the electrical module, out of at least one air outlet of the housing.
