Patent ID: 7817428

Claim:
An electrical enclosure system for transferring heat from a closed environment, comprising: an electrical device including a heat-generating part; and a polymer-based ventless housing for protecting the electrical device from environmental contaminants, the ventless housing fully enclosing the electrical device and having at least three integrated molded layers, the at least three layers including a base layer forming an impact-resistant portion of the ventless housing, the base layer including at least two open areas in close proximity to the heat-generating part, the base layer including a first side and an opposite second side, a first integrated thermally conductive layer molded in a substantially parallel and overlapping manner to an internal surface of the first side of the base layer to form a water-tight union with the base layer, one of the open areas of the base layer being completely covered by the first integrated thermally conductive layer, the first integrated thermally conductive layer forming a first heat-flow path for conducting heat away from the heat-generating part towards an exterior environment, the first integrated thermally conductive layer being fixedly attached to the base layer in an immovable manner, and a second integrated thermally conductive layer molded in a substantially parallel and overlapping manner to an internal surface of the second side of the base layer to form a water-tight union with the base layer, another one of the open areas of the base layer being completely covered by the second integrated thermally conductive layer, the second integrated thermally conductive layer forming a second heat-flow path for conducting heat away from the heat-generating part towards the exterior environment in an opposite direction to the first heat-flow path, the second integrated thermally conductive layer being fixedly attached to the base layer in an immovable manner.
