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

FIELD: usage of heat of secondary power resources in boiler rooms and ventilation systems.

SUBSTANCE: plate-type heat exchanger has stack of aluminum plates with spacer insertions to form channels for working media. Stack is placed inside casing fastened by rods. As spacer insertions the stiffening ribs are used having groove. Internal space of the groove is filled with high-temperature sealing compound to form a layer of sealing compound high as 1-1.5 mm. Stiffening ribs are disposed in perpendicular to surface of aluminum plate and in parallel to each other as well as to board of heat exchange at distance of 150-200 mm. Groove with internal space is formed onto aluminum plate by means of stamping. Air-tightness of assembly is improved due to usage of more efficient swirlers to provide higher efficiency factor of heat exchanger.

EFFECT: improved manufacturability.
