More Information
Summary:The present invention discloses an apparatus that shields electronic equipment from electromagnetic interference. The apparatus is a partially enclosed box having a substantially enclosed cavity. Disposed within the cavity is electronic equipment that is either sensitive to or responsible for generating unwanted EMI radiation. Within each apparatus are cooling air openings. Within each opening is a heat sink device, dimensioned to provide a level of EMI filtering. The heat sink device has a dual function. First, as an EMI filter, it attenuates EMI radiation in the range of frequencies generated by or disruptive to the electronic equipment. Secondly, as a heat sink device, it transfers heat away from the apparatus. In this way, the apparatus of the present invention successfully provides an EMI filter that doubles as a heat sink.
