ABSTRACT:
An enclosure has a set of panels forming an outer peripheral skin. A heat exchanger wall is placed within the panels. A first fan arrangement circulates ambient air into a space within the panels and along the exterior surface of the heat exchanger wall and back into the environment. A second fan arrangement circulates air contained within the enclosure against the interior surface of the heat exchanger wall. Heat is transferred through the heat exchanger wall to the ambient air circulated by the first fan. An inner wall is placed adjacent to the interior surface of the heat exchanger wall. The space between the inner wall and the heat exchanger wall forms a space for the air within the interior of the enclosure to circulate by the second fan. The heat exchanger wall provides a barrier isolating the ambient air from the air within the enclosure, preventing dust, humidity and pollutants to enter into the interior of the cabinet in the space surrounding the electronic components.
