Plate heat exchanger

摘要

Plate heat exchanger has a heat exchanger block (1) with several heat exchange passages. The header (2) is so formed that the cylinder axle runs within the header with a distance (11) to the plain surface (12). The exterior angle (8) averages 87[deg] or smaller or 81[deg] or smaller or 75[deg] or smaller, between the cylinder cover segment shape wall (7) of the header and the side (5) of the heat exchanger block.
