Plate heat exchanger with single and dopple wall plates

摘要

Plate heat exchanger comprises a stack of heat-exchanger plates that are permanently joined together. Separate through flow chambers for at least two heat-exchanger fluids are formed between the heat-exchanger plates. Some of the heat-exchanger plates are designed as single-walled heat-exchanger plates (1) with one plate element and some are designed as double-walled heat-exchanger plates (2a-c) with two plate elements (2a'-2c', 2a''-2c''). Preferred Features: Separate through flow chambers for three heat-exchanger fluids are formed between the heat-exchanger plates.
