    摘要： An electronic cabinet is described which contains both control circuits containing heat producing components and a plurality of circuit breakers. The control circuits and the circuit breakers are located inside the cabinet with heat dissipating fins being located outside of the cabinet in a heat dissipating chimney. Air moves through the chimney by convection and cooperates with the heat dissipating fins to dissipate most of the heat generated by the heat-generating components of the control circuits. Openings are provided in the cabinet to permit cooling air to pass through the interior of the cabinet and over the control circuit components. These two paths of cooling air cooperate to reduce the temperature in the cabinet to a sufficient level to permit the circuit breakers to be located in the same chamber as the control circuits.
