Plate heat exchanger - esp with water cooling,for turbo compressor after-cooler

摘要: A plate heat exchanger, esp. for cooling a compressed gas using liquid, e.g. water, is used example as the after-cooler turbo-compressor; exchanger unit comprises stack, of rectangular cross section, long, plates sealed at their edges to alternate adjacent plates; each undulating or ribbed, so that constitute numerous flow paths having circular sections in one direction and other. The section are liquid open both ends stack into reversal chambers; introduced axially through end cylindrical surrounding casing, with these chambers leading, while other one, which fitted inlet outlet connections, brings up rear flanged housing. path second fluid (gas) leaves from connection vessel wall, diverges this via number guide inside hood spread over side stack; passing downwards bottom, turns outwards towards sides passes separator on side, around outside guiding opposite inlet. Prefd. materials are: exchange chambers, austenitic chrome-nickel steel; outer casing etc., normal structural steel.
