A spiral heat exchanger features first spiral channels configured to form rows and columns of coiled hot fluid pathways to receive hot fluid; and second spiral channels configured to form corresponding rows and columns of coiled cold fluid pathways to receive cold fluid having a temperature less than the hot fluid. The first spiral channels and the second spiral channels are configured to alternate every other row and column so as to form a matrix of alternating rows and columns of coiled hot and cold fluid pathways separated by alternating coiled walls that act as both fluid separators and conduits through which heat is transferred between the hot fluid and cold fluid.

The invention relates to an exchanger device comprising a first and a second end piece (1, 2) and an exchanger body (3, 4) arranged in-between. At least one first and one second channel (150, 151) in the exchanger body (3, 4) connect inlets and outlets (10, 11, 20, 21) of the two end pieces (1, 2), wherein the inlets and outlets (10, 11, 20, 21) are arranged in end faces of the end pieces (1, 2), which face away from the exchanger body. The exchanger body forms a multi-helix, in particular a double helix or multiple concentric ring surfaces, wherein the windings of the multi-helix or the concentric ring surfaces form separating walls (3, 4) between the at least one first and the at least one second channel (150, 151). The device according to the invention allows for the formation of exchanger devices with high efficiency yet also with a small outer diameter. The manufacturing process is also simplified.
