Abstract:
1. An enclosure housing electronic components with an integral heat exchanger arrangement located within the enclosure, comprising: a set of panels forming an outer peripheral skin for the enclosure; at least one air-to-air heat exchanger wall placed within the panels having an interior surface and an exterior surface; a first fan arrangement for circulating 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 for circulating air contained within the enclosure against the interior surface of the heat exchanger wall, wherein heat present in the air within the enclosure is transferred through the heat exchanger wall to the ambient air circulated by the first fan arrangement, the heat generated by the electronic components within the enclosure; and an inner wall placed adjacent to the interior surface of the heat exchanger wall, the space between the inner wall and the heat exchanger wall forming an air space for the air within the interior of the enclosure to circulate by the second fan along the interior surface of the heat exchanger wall; wherein the heat exchanger wall provides, at least in part, a barrier isolating the ambient air from the air within the enclosure preventing dust, humidity and pollutants to enter into the interior of the enclosure in the space surrounding the electronic components; wherein the heat exchanger wall comprises a heat conductive material having a corrugated configuration and having a top edge and a bottom edge, and wherein the enclosure further comprises end cap seals placed adjacent to the top and bottom edges of the heat exchanger wall to prevent ambient air from being drawn into the interior of the enclosure by the action of the second fan arrangement.
