PLATE-TYPE HEAT EXCHANGER Russian patent published in 2011 - IPC F28F3/08 

FIELD: heating.

SUBSTANCE: plate-type heat exchanger includes multiple first and second heat exchange plates located near each other for formation of pack of plates, which has enveloping end side and the first gaps between plates for the first medium and the second gaps between plates for the second medium. The first heat exchange plate forms together with the second heat exchange plate a pair of heat exchange plates. Pack of plates includes a lot of such pairs. Each heat exchange plate has two holes which form passages passing through pack of plates and interconnected with the first gaps between plates. The second gaps between plates are open through the enveloping end side. Every first heat exchange plate includes the first bent part that interacts with bent part of the second heat exchange plate in order to ensure that those two heat exchange plates will occupy the specified position relative to each other. Each hole of the first heat exchange plate interacts with the corresponding hole of the second heat exchange plate to ensure that each pair will occupy the specified position relative to adjacent pairs.

EFFECT: simpler erection of heat exchanger at providing the accuracy of plates attachment.
