A heat exchanger with a monocoque structure transfers heat between a first fluid and a second fluid. The heat exchanger in has a plurality of tubes through which the first fluid may flow in a direction, each of the plurality of tubes has a first mouth end, an N opposing second mouth end and a waist region between the first mouth end and the second mouth end. The heat exchanger also has one or more interconnected fluid channels through which the second fluid may flow, the one or more fluid channels lay generally in a plane, the plurality of tubes and the one or more fluid channels interleave such that heat may be transferred between the plurality of tubes and the one or more fluid channels, and the direction of flow of the first fluid is generally perpendicular to the plane of the one or more fluid channels.

A method for transfer of heat between a first and a second fluid, wherein the first and the second fluid circulate respectively on both sides of a thermally conductive wall of a monobloc assembly formed in a single piece. The monobloc assembly, which is arranged in the interior of a device, includes: a first, three-dimensional, cellular, thermally conductive structure through which the first fluid can pass; at least the thermally conductive wall; and a second, three-dimensional, cellular, thermally conductive structure through which the second fluid can pass. The first and second three-dimensional, cellular structures are situated on both sides of and integral with the wall such that heat transfer is carried out from the first to the second fluid through the wall, and both first and second fluids are under liquid phases and under gaseous phases, with the liquid phases circulating in a direction opposite that of the gaseous phases.
