ABSTRACT:
An apparatus for cooling and warming pole-mounted electronics includes a hollow pole having an upper portion capable of supporting the electronics and a lower portion supported by the ground. An air duct is disposed within the hollow pole such that the hollow pole and the air duct are substantially concentrically aligned about a central longitudinal axis, creating an annular air conduit between the air duct and the hollow pole. A circulating fan is fastened in the lower portion of the hollow pole above ground level. In cooling operation, warm air is drawn downward from the electronics through the air duct, cooled below ground level, and returned via the annular air conduit. The shape of the hollow pole is selected such that at a particular orientation of the sun, the ratio of the shaded surface to the illuminated surface is greater than one.
