PLATE TYPE HEAT EXCHANGER AND PLATE MEMBER FOR IT Russian patent published in 2004 - IPC

FIELD: packs of plate members used in plate type heat exchangers. SUBSTANCE: plate type heat exchanger includes carrying construction with extended carrying apparatus and large number of flat plate members made of heat conducting material and designed for joining with said carrying apparatus in such a way that to rest upon it. On edge of each plate members there is at least one zone for engaging with carrying apparatus and providing snap joint between them. Said zone has at least one elastic part in the form of flexible lever bent in direction cross relative to orientation of joint and parallel relative to plane of plate member. Plate member used in plate type heat exchanger is flat one, it is made of heat conducting material and designed for joining with carrying apparatus in such a way that to rest upon it. On edge of each plate member there is at least one zone for engaging with carrying apparatus and forming snap joint between them. Said zone has at least one elastic part in the form of flexible lever that may be bent in cross direction relative to snap joint orientation and is parallel relative to plane of plate member. EFFECT: possibility for applying maximum effort for assembling separate plates and for engaging members one with another, reduced number of carrying members. 11 cl, 27 dwg
