A fuel gas reformer assemblage for use in a fuel cell power plant is formed from a composite plate assembly which includes spaced-apart divider plates with columns of individual gas passages. The reformer assemblage is constructed from a series of repeating sub-assemblies, each of which includes a core of separate regenerator / heat exchanger gas passages. The core in each sub-assembly is sandwiched between a pair of reformer gas passage skins, which complete the assembly. Adjacent reformer gas / regenerator / reformer gas passage sub-assemblies in the composite plate assembly are separated from each other by burner gas passages. The regenerator / heat exchanger gas passages and the reformer gas passages in each sub-assembly are connected by gas flow reversing manifolds which form a part of each sub-assembly. The fuel gases flow in one end of the assemblage, through the reformer gas passages, and then reverse their direction of flow in the return manifolds so as to exit the reformer assemblage through the regenerator gas flow passages. The burner gases flow in one end of the reformer assemblage and out the other end. The walls of the burner and reformer gas flow passages are selectively catalyzed after the assemblage has been constructed.

A heat dissipation system includes a housing, a circulator and a cooler. The housing has at least one surface made of heat-conductive metal to contact with a heat source. The housing includes a recess with a passage formed on the bottom to contain cooling liquid and an inlet and an outlet connected to the recess. Two pipes are provided to connected between the inlet and the outlet and the cooler, respectively. The circulator is installed in the recess to circulate the flowing of the cooling liquid. As such, heat generated from the heat source is directly conducted to the housing and takes away by the cooling liquid circulated by the circulator to the cooler.

Disclosed are a heat exchanger for a dehumidifier using a liquid desiccant and a dehumidifier using a liquid desiccant having the same. The heat exchanger for a dehumidifier using a liquid desiccant, comprises: a plurality of plate-type heat exchanger bodies to which a heat transfer medium flows through flow paths formed therein; and a plurality of plates extending between the respective heat exchanger bodies, and inclined with respect to the surfaces of the heat exchanger bodies.

The invention relates to a shell and tube heat exchanger used as a coolant mechanism. The shell and tube heat exchanger comprises a plate-fin arranged inside or outside a heat exchanger tube, and at least one heat exchanger tube internally provided with the plate-fin. Through the heat exchanger has simple structure and easy manufacture, the heat exchanger can still limberly process fluid bodies with different shapes, promote the effective heat exchanging action of the fluid bodies, obtain good cooling efficiency, and can process a plurality of fluid bodies. The plate-fin that the invention relates to is the plate-fin for stirring liquid; the plate-fin is arranged inside or outside the heat exchanger tube to lead the fluid bodies which is composed of cooled medium or refrigeration medium to flow inside or outside the heat exchanger tube, thus impingiment flow or vortex flow with stirring action are generated; the plate-fin is arranged inside or outside the heat exchanger tube, and thus the blade edges of the plate-fin are butted and jointed up and down to enable the blade edges opposite to each other, and each butted and jointed blade edges are crossed with each other. The invention also relates to a method for manufacturing the plate-fin as well as the heat exchanger tube internally provided with the plate-fin, and the heat exchanger or an EGR gas cooling device provided with at least one heat exchanger tube.
