Abstract
The compact PCI cabinet includes an inlet port for receiving external air, a set of blowers for drawing the air into the cabinet and for expelling the air from an exhaust port of the cabinet after having cooled internal active circuits, and a plurality of louvers and openings that create thermal convection within a back portion of the compact PCI cabinet to cool active components coupled to the back side of the back plain of the compact PCI system. Additionally, a plurality of perforated air openings located approximately at the bottom and back side of a side panel of the compact PCI cabinet also is included to conduct an receive some air from the external environment. Openings are formed between a plurality of card guides located approximately at the top of the back side of the back portion of the PCI cabinet for conducting air in and out of the back portion of the cabinet. A pin field coupled to a heat sink is placed in the air path between the blowers and the openings through which the air may be conducted into the back portion of the compact PCI cabinet to reduce the exhaust air temperature. Finally, the invention includes a thermistor placed in the exhaust path so that the fan speed of the blowers maybe adjusted according to the temperature of the exhaust after passing through the pin field.
