A heat exchanger component is made by forming a wafer having a pair of opposed outer major faces with interstices between them from a stack of wire mesh screens. The outer major surfaces of the wafer are sealed by depositing a metal coating on them. The deposited metal coatings define between them a flow path for a heat exchange fluid extending through the interstices of the wafer.

Method of making a heat exchange component using wire mesh screens

A heat exchange device of a type for affecting an exchange of heat between a first and second fluid is characterized by a plurality of heat exchange cells in a stacked arrangement wherein each cell includes inlet and outlet manifold rings which define inlet and outlet manifolds, respectively. Adjacent heat exchange cells are bonded to one another via metallurgical bonds between the contacting surfaces of the manifold rings. In a further aspect, a method for the manufacture of a heat exchange device is provided.

Heat exchange device and method for manufacture

A heat exchange device of a type for affecting an exchange of heat between a first and second fluid is characterized by a plurality of heat exchange cells in a stacked arrangement and defining first, second and third manifolds. In certain aspects, an apparatus and method for reinforcing the heat exchange device against pressure loads while accommodating thermal expansion of the outlet manifold are provided.

Heat exchanger with pressure and thermal strain management

An apparatus and method are provided for permitting free rotation of turbine nozzle vanes, while minimizing or eliminating leakage on the vane side-walls. The device incorporates a plurality of nozzle vanes arranged around the circumference of a radial or mixed inflow turbine. Each of the nozzles is individually attached to a rod positioned perpendicular to the flow direction. The nozzle rods in the circumferential array protrude through a movable annular back-wall, and are rotated by a linkage or gear. Between discrete movements of the vane mechanism, a bellows device is used to provide pressure-actuated force in the movable back-wall, thereby clamping the nozzle between the two surfaces. Prior to rotating the nozzles, pressure within the bellows interior is decreased via venting to cause a retraction of the back wall.
