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 associated with a vibration generator to undergo a mechanical vibration which causes the dirt particles deposited on the surface to be dislodged.
Claims12
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;
- at least one vibration generator associated with the at least one membrane filter, the at least one vibration generator causing the at least one membrane filter to undergo a mechanical vibration to cause the dirt particles deposited on a surface of the at least one membrane filter to be dislodged;
- and
- at least one cooling device for establishing an air flow 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.
