A method for producing heat exchangers having at least two fluid circuits each having channels, including the following steps: producing one or a plurality of elements of a first fluid circuit, each element having at least two metal plates, at least one of which has first grooves; stacking the at least two metal plates of each element in such a way that the first grooves form the channels of the first circuit; assembling each element of the first circuit by diffusion welding between the two stacked metal plates; producing one or a plurality of elements of at least one second fluid circuit, each element of the second circuit having at least a portion of the channels of the second circuit; assembling, either by diffusion welding, or by brazing, or by diffusion brazing between the element or elements of the first circuit and the element or elements of the second circuit.

Method for producing a heat exchanger module having at least two fluid flow circuits

The present invention relates to an novel method of producing heat exchangers having at least two fluid circuits each comprising channels, the method employing diffusion bonding achieved using the hot isostatic pressing (HIP) technique, and to a heat exchanger obtained using this method.

Method for producing a heat exchanger module with at least two fluid circulation circuits and heat exchanger obtained using this method

A solar power tower solar receiver absorber including: an enclosure; at least one panel configured to be illuminated by solar flux; a core made of at least one material with heat conductivity at least partially encompassed by the enclosure; and a plurality of tubes passing through the core and extending substantially in a parallel direction with respect to the panel configured to be illuminated. The tube is configured for circulation of a fluid to be heated, for example a gas for operating a gas turbine.

Solar receiver absorber and solar receiver comprising at least one such absorber
