摘要

protiproudu00fd cylindrical rekuperacnu00ed vu00fdmenu00edk (1) has inputs (11) media usporu00e1du00e1ny radiu00e1lne, possibly semiradiu00e1lne,at the end prstencovitu00e9m rozdelovaci (17) and paprskovite in relation to the longitudinal axis (4) rekuperacnu00edho vu00fdmenu00edku (1),and connecting to the channels (9) usporu00e1danu00e9 between vnejsu00ed pipe (2) and the inner pipe (3) for proudenu00ed media.the outputs (12) media has rekuperacnu00ed vu00fdmenu00edk (1) usporu00e1du00e1ny axiu00e1lne at the tail end prstencovitu00e9m rozdelovaci (17) and paprskovite in relation to the longitudinal axis (4) rekuperacnu00edho vu00fdmenu00edku (1),and connecting to output channels (10) for proudenu00ed media.teplosmennu00e9 area (5) are cross oddelenu00e9, in line, vu00edcechodu00e9, sroubovite stocenu00e9 between vnejsu00ed pipe (2) and the inner pipe (3),and defining the cross oddelenu00e9 input channels (9) and the output channels (10) for proudenu00ed media.teplosmennu00e9 area (5), and tudu00edz input channels and output channels (9) and (10) are usporu00e1danu00e9 paprskovite around the longitudinal axis (4) rekuperacnu00edho vu00fdmenu00edku (1).teplosmennu00e9 surface shaped surfaces resulting tazenu00edm tvoru00edcu00edho profile (8, 16) after vnejsu00edch sroubovicu00edch (6) and (7), where vnitrnu00edch sroubovicu00edch profile (8, 16) has a shapein pru00edcnu00e9m reza perpendicular to the longitudinal axis (4) rekuperacnu00edho vu00fdmenu00edku (1), from the group comprising of the stripes, kruznice, spiral, evolventy, parables and hyperboly.
