The present invention provides a heat exchanger comprising a stack of heat conducting plates, wherein each plate is provided with generally a spiral-deformation defining crests and troughs, the troughs on one side of the plate corresponding to the crests on the other side of the plate, and wherein the plates are stacked such that the crests on adjacent plates abut to divide the space between the plates into a generally spiral channel, the ends of which communicate with connecting channels arranged perpendicular to the planes of the plates, the channels on opposite sides of each plate being connected for flow of different fluids between which heat is to be exchanged. |
