(54)HEAT EXCHANGER HEAT TRANSFER PLATE


(57) A plate for a heat exchanger has a longitudinal centerline, a reference plane parallel to the longitudinal centerline, and multiple corrugations provided in the plate that define flow channels through which fluid flows. The corrugations extend at an angle to the reference plane and at least some of the corrugations are intersected by the reference plane, wherein over at least a portion of a surface area of the plate the corrugations are arranged in sub-regions that have a longitudinal length and the corrugations of each sub region are at the same angle relative to the longitudinal centerline, and the corrugations of adjacent sub-regions are at different angles from each other, and wherein the corrugations in adjacent sub-regions meet at junctions and the junctions are not longitudinally aligned.
