Abstract: A cooling assembly is disclosed having a device chamber, a cooling chamber, a heat exchanger, a fan and a controller, the heat exchanger having a first heat exchanger unit and a second heat exchanger unit located above the first heat exchanger unit. The fan includes a first fan adapted to generate a first cooling air flow. The cooling assembly further includes a first dust tray located between the first heat exchanger unit and the second heat exchanger unit, the first cooling air flow being directed towards the first dust tray, the first dust tray being adapted to receive and retain at least part of contaminant particles present in the first cooling air flow, the device chamber being separated from the cooling chamber.
