Abstract
A method for producing a brazed plate heat exchanger comprising a stack of heat exchanger plates provided with a pressed pattern adapted to provide contact points between neighboring heat exchanger plates, such that the heat exchanger plates are kept on a distance from one another under formation of interplate flow channels for media to exchange heat, wherein the interplate flow channels are in selective communication with port openings for the media to exchange heat and circumferentially sealed along an outer periphery in order to avoid external leakage, comprises the following method steps: a. Calculating the position of the contact points between neighboring plates; b. Calculating a force that must be transferred by each contact point when the heat exchanger is in use; c. Based on the method steps above, calculating a necessary amount of brazing material for each contact point; d. Providing a screen for screen printing the brazing material onto the heat exchanger plates, wherein the screen is provided with openings, the size, position, plate thickness and shape of which being adapted to provide the necessary amount of brazing material to each contact point; e. Screen printing th…
