PLATE-TYPE HEAT EXCHANGER Russian patent published in 2005 - IPC

FIELD: heat-power engineering; heat exchange apparatus; power engineering; chemical, food-processing and other industries.

SUBSTANCE: proposed plate-type heat exchanger includes hold-down plates and stack of corrugated plates with angular collector holes, distributing tubes mounted in angular holes of hold-down plates and plates of stack; distributing tubes have through longitudinal slots in their center part which are used for passage of heat-exchanging media, bearing bead on one end and external thread on other end; distributing tubes may be used for compression of plates of stack by hold-down plates by means of nuts screwed on thread; holes of distributing tubes are blanked-off on side of bearing bead; external surfaces of center part of tubes are made at clearance relative to holes of plates of stack for proper positioning of plates during assembly; holes of hold-down plates are provided with seals over engageable external surfaces of tubes.

EFFECT: reduced overall dimensions of heat exchanger; enhanced compactness; ease of mounting.
