A plate for a heat exchanger including front and back external surfaces, a periphery, one or more dry internal passages through which a fluid flows parallel to the first and second stream-wise edges, and an internal frame. The frame is coincident with the periphery of the plate. The front edge section and the back edge section of the frame permit a fluid to flow into and out of the internal passages of the plate. The frame is bonded to the front and back external surfaces of the plate around the plate's periphery. The plate further includes fins or other protuberances that enhance heat transfer between a fluid flowing within the plate and the external surfaces of the plate, the fins or other protuberances being located within a volume defined by the frame and the plate's external surfaces.
