HEAT-EXCHANGE APPARATUS Russian patent published in 2009 - IPC F28C3/06 

FIELD: heat-and-power engineering.

SUBSTANCE: invention relates to heat-exchange apparatus, provided for implementation of interaction of air and water (or other liquid) excluding direct contact of these mediums and at high volumes. Heat-exchange apparatus contains casing with branches of inlet and outlet of water and air, separator and overflow, several heat exchanging elements located over case bottom, herewith each of heat exchanging elements is outfitted by air threaders with blades, fixed on annular plate, exhaust tube, installed on top edges of blades, herewith exhaust tubes are affixed to branch of air exhaust from apparatus, branches of inlet and outlet of cooled water from apparatus are built-in into branch of air exhaust from apparatus, and in bottom parts of exhaust tubes of heat exchanging elements there are located heat exchangers with branches of inlet and outlet of water, herewith inside top parts of exhaust tubes of heat exchanging elements co-axial to it there are located drums, divided by inner partitions lengthwise vertical axis for two parts, one of which is outfitted by branch of water inlet, and other - by branch of water outlet, herewith partitions are fixed by top butts to covers of tanks, and bottom butts are not reaching the bottom of tanks, between outer surfaces of tanks and inner surfaces of exhaust tubes there are fixed plate fins, branch of water inlet into tanks is fixed to inlets of water into apparatus, and branch of outlet of water from tanks is fixed to branch of water inlet into heat exchangers, located in the bottom part of exhaust tubes, and branch of water inlet from these heat exchangers are fixed to outlets of cooled water from apparatus.

EFFECT: providing of double-stage high-performance heat passage from air to water.
