Heat exchanger with new plate design - comprises ribbed plates with two metallic sheets and intermediate sheet which is good conductor or form not extending beyond exchanger zone

摘要

The exchanger is made up of a determined number of ribbed plates (1), each ribbed plate (10 is secured by the pressing of a complex made up of two metallic sheets (7a,7b). Confined between each metallic sheet is a sheet (8) of material that is a good conductor of heat and presenting characteristics greater than those of the external sheets (7a,7b). The intermediate sheet (8) has the dimensions and the form such that it may be disposed between the external sheets in a zone of exchange without extending beyond the zone (9) or may be disposed in the peripheral joint (6). ADVANTAGE-Improved performance.Provides security of use and eliminates risk of accidental contact between inlet and outlet fluids for example in case of perforation of walls.
