FIELD: power industry. ^ SUBSTANCE: plate-type heat-exchanger includes several plates, each plate has heat carrying zone, periphery zone that extends around and outside heat carrying zone and several channels that go through heat-exchanger plate and are located inside and close to periphery zone. Channels are defined by edge and have centre. Channel edge has first part that faces periphery zone and second part that faces heat carrying zone. The first part of edge has corrugation that is seen through channel centre. The second part of edge actually has flat form seen through channel centre. ^ EFFECT: possibility to increase heat-exchanger input holes and reduction of particles sticking to channel walls. ^ 11 cl, 9 dwg |
