A plate-fin type heat exchanger without sealing strip, includes outer shield plates (), nozzles (), several heat exchanging plates () with fins () and peripheral sealing inclined plane (). Among the heat exchanging plates (), the heat exchanging fins () in at least one heat exchanging medium flow layer are transversely provided.

Plate-fin type heat exchanger without sealing strip

A rib plate type heat exchanger comprises a heat exchange core consisting of rib plate type heat exchange plates. A surrounding edge of the rib plate type heat exchange plate is formed as a sealing bevel. The rib plate type heat exchange plate comprises the first end zone, the second end zone and a central heat exchange zone. The first and second distribution zones are provided in the first and the second end zones respectively. The central heat exchange zone and first and second distribution zones are arranged on a same plane and are extended in the height of a lower plate plane. Heat exchange ribs and flow guide ribs are provided in the central heat exchange zone and the distribution zones respectively. Corner holes which are surrounded by adjacent edge zones at the upper plate plane height and lower plate plane height are provided in the first end zone and the second end zone. There are incline intermediate zones extending between the adjacent edge zones, between the adjacent edge zone at the upper plate plane height and the central heat exchange zone, and between the adjacent edge zone at the upper plate plane height and the first and second distribution zones.
