Shell and plate heat exchanger

摘要: The present invention relates to a plate heat exchanger and its method of construction. A pair round corrugated transfer plates provide cassette with the corrugations one angled relative other so as form angular channels for fluid flow primary secondary fluid. plurality cassettes are contained within housing provided port holes. is in cylindrical shell includes bottom cover member top member. has an inlet nozzle outlet on opposed sides while nozzles aligned holes formed each cassettes. Depending type use, either portholes or outer edge may be welded, gaskets used alternately fouling side(s). gasketed semi-gasketed allows unit cleaned side when concern. spring device compensate any mechanical thermal expansion that occur during operation exchanger. Also, special seal preventing short-circuiting it passes through
