Abstract
A plate heat exchanger for solar heating includes a plurality of channels extending between an inlet and an outlet for conducting a heat transferring fluid. The plurality of channels is defined between a first plate and a second plate, the first and second plates being formed by stainless steel. Each of the plurality of channels has a single-curved extension between the inlet and the outlet as seen in a plane corresponding to the major surface extension of the first and second plates. Each of the plurality of channels has along at least a portion of its longitudinal extension a triangular or a chamfered triangular cross-section or a parallelogram or a chamfered parallelogram cross-section. The side walls of two adjacent channels define an angle α corresponding to, or smaller than, 100 degrees and more preferred smaller than 90 degrees.
