    摘要: A marine heat exchanger has a low profile header and cooling tube configuration to minimize drag and maximize heat transfer during use. The cooling tubes extend from at least an underside of the header so that the header vertically disposed cross sectional area is minimized and the cooling tubes are exposed to flowing seawater prior to or along with the headers. The tubes can also extend forwardly of the header to further maximize heat transfer and minimize drag. The header construction is especially adapted for hulls without recesses for header containment.

    摘要: A first water header is connected to a second water header by laterally-spaced multiple parallel composite tubes, each consisting of two or more component tubes of vertically-elongated rectangular cross-section welded to one another along their horizontal narrower adjoining faces, the height of each component tube being a multiplicity of times the width thereof. The thus welded faces form intermediate partitions or webs of doubled thickness running the entire length of the composite tube. This greatly strengthens the composite tube thus obtained and also divides the cooling water flow into vertically-spaced thin streams or bands of cooling liquid. Rising from the first and second headers are first and second fittings which serve not only to transmit the cooling water into and out of their respective headers but also serve to connect and attach the header to the keel or other underwater location of the heat exchanger to the hull of the boat or vessel. One or more intermediate supports are secured transversely to the upper faces of the conduit and have threaded stems which also pass upward through the keel or other underwater part of the hull to which the heat exchanger is attached.
