摘要： A heat exchanger for transferring heat between an external fluid and an internal fluid includes two or more heat exchange cells, each heat exchange cell having a top plate with an inlet aperture at one end thereof and an outlet aperture at the other end thereof, the top plate including a first surface, a second surface and peripheral edges. The heat exchange cell also includes a bottom plate juxtaposed with the top plate, the bottom plate having an inlet aperture at one end thereof and an outlet aperture at the other end thereof. The bottom plate includes a first surface, a second surface and peripheral edges. The peripheral edges of the top and bottom plates are attached to one another, the second surfaces of the top and bottom plates confronting one another and the inlet and outlet apertures of the top and bottom plates being in substantial alignment with one another. The attached top and bottom plates define a high pressure chamber between the second surfaces thereof. The inlet and outlet apertures of the top and bottom plates including substantially curvilinear S-shaped raised flange portions extending away from the first surfaces of the plates, the substantially curvilinear S-shaped raised flange portions terminating at interior edges bounding the apertures. Each heat exchange cell includes an internal finned member disposed between and attached to the second surfaces of the respective top and bottom plates, wherein the individual heat exchange cells are assembled one atop the other with the interior edges of adjacent heat exchange cells attached together for forming a compliant bellows structure capable of elastically absorbing deflections produced during thermal loading so that the heat exchange cells may move and flex relative to one another.

摘要： A method of making a heat exchanger includes assembling one or more heat exchange cells. Each heat exchange cell is assembled by providing a top plate having an inlet aperture at one end thereof, an outlet aperture at the other end thereof, a first surface, a second surface and peripheral edges; and providing a bottom plate having an inlet aperture at one end thereof, an outlet aperture at the other end thereof, a first surface, a second surface and peripheral edges. The second surfaces of the top and bottom plates are juxtaposed with one another so that the inlet and outlet apertures of the plates are in substantial alignment with one another. The peripheral edges of the top and bottom plates are attached to form a high pressure chamber between the second surfaces of the plates. After being assembled, each individual heat exchange cell is tested before being attached to other heat exchange cells. The testing may include pressure testing of the heat exchange cell. The testing of each individual cell improves the quality and reliability of the fully assembled heat exchanger because each level of the heat exchanger has been pre-tested for defects (e.g. leaks) prior to further assembly steps.

摘要： This disclosure relates to a highly efficient gas turbine engine architecture utilizing multiple stages of intercooling and reheat, ceramic technology, turbocharger technology and high pressure combustion. The approach includes utilizing a conventional dry low NOx combustor for the main combustor and thermal reactors for the reheat apparatuses. In a first configuration, there are three separate turbo-compressor spools and a free power turbine spool. In a second configuration, there are three separate turbo-compressor spools but no free power spool. In a third configuration, all the compressors and turbines are on a single shaft. Each of these configurations can include two stages of intercooling, two stages of reheat and a recuperator to preheat the working fluid before it enters the main combustor.

摘要： A metallic-ceramic joint for a turbo-compressor spool is disclosed. A temperature-limited joint is moved from outside the bearings to between the bearings and near the center of the shaft joining the turbine and compressor. This placement can lower the temperature at and around the joint and reduces the sharp gradient (and associated thermal stress) naturally occurring between the turbine rotor and the cooler joint. The bearing closest to the compressor can be an oil bearing and the bearing closest to the turbine an air bearing. The bearing closest to the compressor and the bearing closest to the turbine can both be an oil bearing. The bearing closest to the compressor and the bearing closest to the turbine can both be an air bearing. Moving the metallic-ceramic joint between the bearings can provide sufficient isolation to enable the all-air bearing solution.

摘要： A solar receiver for conversion of solar radiation to thermal energy includes an enclosure defining a cavity and having an aperture for receiving an influx of concentrated solar radiation. A heat exchanger is received within the cavity for transferring heat out of the solar receiver. The heat exchanger comprises a plurality of heat exchange cells arranged in polygonal array within the cavity. Each heat exchange cell comprises an inlet, an outlet, and a heat exchange matrix interposed within a first volume defined between a first plate and a second plate spaced apart from the first plate. The inlet and outlet are in fluid communication with the first volume and the first plate, second plate, and heat exchange matrix are monolithically bonded as a unit. The first plate receives concentrated solar radiation and the heat exchange media defines a pathway for a fluid flowing from the inlet to the outlet between the first and second plates. The solar receiver further includes an inlet manifold in fluid communication with the inlet of each of the heat exchange cells and an outlet manifold in fluid communication with the outlet of the each of heat exchange cells. In a further aspect, a heat exchanger is provided.
