摘要： Unheated external air is drawn into an electronic component housing (200). The external air is selectively heated to form heated air (209) and the extent of the heating is based at least in part upon the temperature within the electronic component housing (200). The heated air (209) or the unheated external air (206) is drawn across at least one electronic component (210) positioned within the electronic component housing (200). A first flow (222) of either the heated air or the unheated external air is selectively exhausted from the electronic component housing (200). A first amount of the first flow (222) is based at least in part upon the temperature within the electronic component housing. A second flow (216) of either the heated air or the unheated external air is selectively re-circulated within the housing. A second amount of the second flow (216) is based at least in part upon the temperature within the housing (200). The influx, heating, exhausting, and re-circulating operate so as to cause the temperature within the housing (200) to stay within a predetermined range.
