ABSTRACT:
An electronic circuit module includes a smaller than normal size printed wire board and an adaptor plate to fit the printed wire board into a slot of a rack made for normal size modules. A diverter fixed to the adaptor plate funnels cooling air over the adaptor plate to the printed wire board and a cover contains the air flow next to the adaptor plate and printed wire board. A cover is provided for blocking off empty slots of the rack from air flow and a dummy module is positioned to separate modules from any adjacent empty space so as to assure and adequate supply of cooling air to the electronic circuit components of the modules.
