Claim of US Patent No. 9,402,332

1. A shielding cage comprising:
a conductive cage body including a plurality of walls that cooperatively define a hollow interior module-receiving bay which
is configured to receive an electronic module therein, the cage body further including an opening through which the electronic
module may be inserted or removed from the module-receiving bay;

an air guide for guiding air into the interior of the module-receiving bay, the air guide being disposed on one of the cage
body walls, the air guide including at least one hollow entry passage disposed therein, the entry passage communicating at
a first end thereof with the surrounding atmosphere, and the entry passage communicating, at a second end thereof, to the
interior of the module-receiving bay; and,

a thermal transfer member also disposed on one of the cage body walls, the thermal transfer member including at least one
hollow exit passage extending therein, the exit passage communicating at a first end thereof to the interior of the module-receiving
bay and the exit passage, communicating, at a second end thereof to the surrounding atmosphere;

whereby the air guide, the module-receiving bay and the thermal transfer member cooperatively define an air flow cooling passage
that extends into the shielding cage body and is configured to flow across at least one surface of the electronic module and
out of the shielding cage body so as to facilitate removal of heat from the module-receiving bay.
