Abstract
The invention refers to a plate heat exchanger where the heat exchanger comprises a first flow channel between a first plate and a second plate, and where the flow channel comprises a lower distribution passage, a heat transfer passage and an upper distribution passage, where the heat transfer passage is vertically divided in a lower and an upper heat transfer passage and where the lower heat transfer passage is horizontally divided in a plurality of adjacent heat transfer zones, where the intermediate angle between the ridges and grooves in any of the heat transfer zones of the lower heat transfer passage is at least 30° larger than the intermediate angle of the ridges and grooves of the upper heat transfer passage. The advantage of the invention is that an improved heat exchanger is provided, having an increased thermal performance and an improved evaporation capacity.
