Air baffle assembly for electronic circuit mounting frame

An assembly comprising:

• an electronic mounting frame adapted to receive and maintain in parallel spaced relationship a maximum member of electronic elements;
• at least one and less than the maximum number of electronic elements inserted into the electronic mounting frame, each occupying an amount of space within the electronic mounting frame;
• and
• a baffle assembly inserted into the electronic mounting frame in place of a selected given number of electronic elements and including first and second end boards mounted in the electronic mounting frame on opposite sides of a space for receiving the selected given number of electronic elements as though the first and second end boards were printed circuit boards of a printed circuit board assembly and a web member having a plurality of slats extending between facing surfaces of the first and second end boards, the slats being disposed in parallel sliding relationship to immediately adjacent slats to permit the web member to be deployed and retracted as the distance between the facing surfaces is increased and decreased respectively to accommodate the size of the space, the web member having a plurality of apertures therein presenting an impedance to a flow of air through the space approximating an impedance presented by a maximum number of electronic elements within the space.

An assembly comprising:

• an electronic mounting frame having a given number of oppositely disposed pairs of slots adapted to receive and maintain in parallel spaced relationship a given number of electronic elements;
• at least one and less than the given number of electronic elements disposed within the mounting frame, each of the at least one electronic elements being received and maintained in place by a different pair of slots;
• and
• a baffle assembly inserted into the electronic mounting frame in place of a selected given number of electronic elements and including first and second planar end boards, each being received and maintained in place on opposite sides of a space by a different pair of slots and a web member including a substantially planar member extending between facing surfaces of the first and second planar end boards, the web member being hingedly secured to the first end board and slideably secured to the second end board so as to slide in the plane of the second end board and thereby accommodate changes in the distance between the first and second end boards, the web member having a plurality of apertures therein presenting an impedance to a flow of air through the space approximating an impedance presented by a maximum number of electronic elements within the space.
