SYSTEM AND METHOD FOR ENVIRONMENTAL CONTROL OF AN ENCLOSURE
First Claim
1. A method of controlling a temperature within an electronic component housing comprising:
- selectively drawing unheated external air into the electronic component housing;
selectively heating the external air that is drawn into the electronic component housing to form heated air, an extent of the heating based at least in part upon the temperature within the electronic component housing;
drawing a selected one of the heated air and the unheated external air across at least one electronic component positioned within the electronic component housing;
selectively exhausting from the electronic component housing a first flow of the selected one of the heated air and unheated external air that has been drawn across the at least one electronic component, a first amount of the first flow based at least in part upon the temperature within the electronic component housing;
selectively re-circulating within the electronic component housing a second flow of the selected one of the heated air and the unheated external air that has been drawn across the at least one electronic component, a second amount of the second flow based at least in part upon the temperature within the housing; and
wherein the influx, heating, exhausting, and re-circulating operate so as to cause the temperature within the electronic component housing to stay within a predetermined range.

Abstract
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.

10. A system comprising:
-
a housing; an entrance portal extending through the housing; at least one heater positioned within the housing and in communication with the entrance portal, the at least one heater adapted to selectively heat external air flowing through the entrance portal to form heated air based upon a temperature within the housing; an air flow control device; at least one electronic component positioned between the at least one heater and the air flow control device; wherein the air flow control device is adapted to draw the heated air across the at least one electronic component and selectively direct a flow of the air that has been drawn across the at least one electronic component into at least one of a plurality of pathways based upon the temperature within the housing; and wherein an amount of the flow into each of the plurality of passageways is chosen and the activation of the at least one heater is made so as to cause the temperature within the housing to stay within a predetermined range. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
