A PLATE HEAT EXCHANGER WITH VARYING FLANK INCLINATIONS

Patentradars sammanfattning

SWEP International AB discloses a brazed plate heat exchanger in which the corrugated heat exchanger plates carry ridges and grooves whose opposing first and second flanks have deliberately different inclination angles. The key novelty is that the inclination of at least the first flank varies both along the length of individual ridges/grooves and between different ridges/grooves across the plate surface. This spatial variation of flank inclination controls local inter-plate channel volume and pressure drop, guiding fluid away from inlet ports into less-accessible regions of the flow channel and thereby improving overall heat transfer uniformity.
