VERTICAL FILM-TYPE HEAT EXCHANGER Russian patent published in 2004 - IPC

FIELD: chemical and microbiological industries; heat engineering.

SUBSTANCE: the invention presents a vertical film-type heat exchanger intended for application in heat engineering, in particular, in the vertical film-type heat exchangers used in microbiological, chemical and medical industries. The vertical film-type heat exchanger contains feeding and withdrawing manifolds connected by a bunch of vertical heat-transfer pipes, each of which is supplied with a film distributor. At that the film distributor is made in the form of a blind plug mounted with a clearance over the upper butt a heat-transfer pipe and with formation of an ring-type clearance with an internal surface of a heat-transfer pipe. At that along periphery of the film distributor there are slots directed to one side at an angle to a generatrix of the heat-transfer pipe. The elastic plates shutting down outlets of the slots funnel are executed. Elastic plates are fixed in a cantilever way to the lower part of the film distributor. Besides the slots on the periphery of the film distributor are made under different angles to the generatrix of the heat-transfer pipe. The invention allows to increase a surface-area factor and to reduce a consumption of refrigerant.

EFFECT: the invention allows to increase a surface-area factor and to reduce a consumption of refrigerant.
