Enclosure for electrical and electronic equipment with temperature equalization and control

An enclosure for electrical equipment, said enclosure including two sections side by side and interconnected at each end;

• an air inlet connected to one section at one end;
• an air outlet connected to the other section at said one end;
• a pivotally mounted baffle at said one end, moveable alternately to one of a first position and a second position;
• the baffle isolating said sections from said inlet and outlet and permitting connection between sections at said one end in said first position for continuous circulation through both sections, the baffle preventing connection between sections at said one end opening said sections to said inlet and outlet in said second position for circulation from said inlet through said sections to said outlet;
• a first fan operable to continuously circulate air through said sections when said baffle is in said first position;
• a second fan operable when said baffle is in said second position, to assist in circulating air from said inlet to said outlet through said sections;
• heat responsive means to move said baffle from said first position to said second position when the temperature in said enclosure exceeds a predetermined value.
