    摘要: A heat exchanger is provided for transferring heat between a first fluid flow and a second fluid flow. The heat exchanger includes a first fluid flow path having a major dimension and a minor dimension and a second fluid flow including at least two flat tubes each having a major dimension and a minor dimension. Each of the flat tubes have at least two passes. Each tube has a transition region joining adjacent passes. Each transition region extends beyond the first fluid flow path major dimension.

    摘要: Large thermal stresses are avoided and the fuel charge reduced in a vaporizer particularly suited for use in a reformer type fuel cell system and having a construction that includes alternating fuel/water flow path defining cells (68) and hot gas flow path cells (69) by providing heat transfer augmentation, such as a lanced and offset fin (120), only in that part of the gas flow path structure (69) adjacent the regions in the fuel/water flow path cells (68) where heating of the liquid fuel/water and vaporizing of the fuel/water where the mixture exists is a two phase material occurs and not in the area adjacent those parts of the fuel/water flow path structure (68) in which superheating of the vaporized fuel/water mixture is occurring.
