Abstract
A heat exchanger comprises a number of identical heat exchanger plates stacked in a stack. Every other heat exchanger plate is turned 180 degrees in its plane relative to its neighboring plates, and each heat exchanger plate comprises at least four port openings and a herringbone pattern comprising pressed ridges and grooves. The ridges and grooves are adapted to keep the plates on a distance from one another under formation of flow channels, wherein areas around the port openings are arranged on different levels, such that selective flow from the port openings to the flow channels is achieved. Dents are arranged in the ridges and grooves in the vicinity of any of the port openings, the dents being arranged to increase the flow resistance to promote a more even flow distribution in the flow channel.
