摘要： An apparatus and methods are provided for finless heat exchanger cores. A heat exchanger core includes an inlet header and an outlet header. The heat exchanger core also includes one or more curved channel frames disposed at least partially between the inlet header and the outlet header. The one or more curved channel frames have a first end and a second end, and one or more fluid passageways that direct flow of a first fluid in a first direction therethrough from the first end to the second end. In some embodiments, at least one of the one or more curved channel frames includes a rounded leading edge and a tapered trailing edge.

摘要： A tube for a thermal transfer device can include a wall having a length and having an inner surface and an outer surface, wherein the inner surface forms a cavity. The tube can also include at least one first dimple pressed into the wall toward the cavity at a first location along the length of the wall, where the inner surface of the wall at the at least one first dimple is separated from itself by a first distance. The tube can further include at least one second dimple pressed into the wall toward the cavity at a second location along the length of the wall, where the inner surface of the wall at the at least one second dimple is separated from itself by a second distance. The cavity can be configured to receive a fluid that flows continuously along a length of the at least one wall.

摘要： A fuel cell device includes: a reformer that generates a reformed gas; a fuel cell; a combustor that combusts off-gas of the reformed gas and air for power generation, and generates a combustion exhaust gas; a first air heat exchanger that has a combustion exhaust gas path and a first air supply path, and that performs heat exchange between the combustion exhaust gas and the air for power generation; a fuel cell storage which stores the fuel cell; a second air heat exchanger that has a second air supply path that supplies the air for power generation to the fuel cell, and that performs heat exchange between the off-gas of the air for power generation and the air for power generation; and a housing that stores members. The first air supply path and the second air supply path are disposed to cover whole members stored in the housing.

摘要： To provide a heat exchanger that can control temperatures of fluids to be heat-exchanged. A heat exchanger 30 includes a honeycomb structure 1, a second fluid flow through portion 26 located at an outer periphery side of the honeycomb structure 1 serving as a flow passage for a second fluid, and a third fluid flow through portion 27 located at an outer periphery side of the second fluid flow through portion 26 serving as a flow passage for a third fluid. Cells 3 of the honeycomb structure 1 serve as a first fluid flow through portion 25 through which the first fluid passes. With the heat exchanger 30, the first fluid, the second fluid, and the third fluid can be heat-exchanged without being mixed with one another. Constituting the fluid flow passage with three flow passages allows controlling temperatures of two fluids to be heat-exchanged by the residual fluid.
