ASSEMBLED PLATE-TYPE HEAT EXCHANGER Russian patent published in 2015 - IPC F28F3/00 

FIELD: heating.

SUBSTANCE: invention refers to heat engineering and can be used in plate-type heat exchangers. An assembled plate-type heat exchanger includes multiple assembled headers. Each header has a pair of elongated flat plates installed one after another at some interval. An additional wall is located between a pair of flat plates and attaches peripheral edges of the pair of flat plates to each other. Each plate has two end parts, in each of which there is a through hole. Multiple assembled headers are aligned in a line along the first and the second axes passing through holes made in each end part. With that, the additional wall includes spacing gaskets located partially around each hole in each end part and the first tie-rods located along each lateral edge of the pair of elongated flat plates. A path of the first medium flow passes through multiple assembled headers along the first axis and leaves the multiple assembled headers along the second axis. Multiple paths of the second medium flow pass between adjacent headers and are hydraulically isolated from the path of the first medium flow, thus being in thermal contact with it.

EFFECT: increasing strength.
