PROBLEM TO BE SOLVED: To provide an apparatus for exchanging heat between a first fluid and a second fluid, a method and the apparatus for exchanging heat in a gas turbine engine. SOLUTION: A heat exchanger comprises a stack of at least two layers of support structures, wherein each support structure layer is formed from a lattice of support members, and essentially fluidly separating the at least two support structure layers using at least one barrier such that each layer defines a fluid passageway. Further, in this method, the flow of the first fluid is guided through the first fluid passageway, and the flow of the second fluid is guided through the second fluid passageway being adjacent to the first fluid passageway, thus facilitating exchanging heat between the first and second fluids.
