    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.

    摘要: A multi-pass heat exchanger is provided. The multi-pass heat exchanger may be used in a fuel processing subsystem for cooling a reformate flow or in any other application where uniform outlet temperatures are desired. The multi-pass heat exchanger includes a plurality of tube run groups having a first pass, an intermediate pass and a final pass. The respective locations of the passes relative to each other provide more uniform outlet temperatures than conventional automotive-style, parallel flow, single-pass heat exchangers.

    摘要: The present invention provides a water vaporizer including a first flow path connected to a water inlet, a second flow path for receiving superheated water vapor from the first flow path and being connected to a vapor outlet to exhaust the superheated water vapor, and a third flow path extending between an exhaust inlet and an exhaust outlet and being oriented to transfer heat from an exhaust flow to the superheated water vapor. The water vaporizer can also include a first convoluted fin positioned along the second flow path, and a second convoluted fin positioned along the second flow path adjacent to and separated from the first fin to define a gap extending between the first and second fins along a length of the first fin in a direction substantially parallel to the exhaust flow along the third flow path.

    摘要: A catalytic reactor including a heat exchanger and a method are provided for transferring heat to a coolant and a reaction fluid. The catalytic reactor includes a reaction fluid flow path, a reaction region, and a coolant flow path. A reaction fluid catalytically reacts at a surface area in the reaction region thereby generating heat. The heat is transferred to a coolant and the reaction fluid based on the coolant and reaction fluid convective heat transfer coefficients respectively. In one embodiment, the ratio of the coolant convective heat transfer coefficient to the reaction fluid heat transfer coefficient is at least 5:1.
