HEAT EXCHANGER Russian patent published in 2009 - IPC F24F7/08 

FIELD: heating.

SUBSTANCE: invention deals with design of a heat exchanger for indoor conditioning by way of exchange of heat between the indoor and the outdoor air by way of fan-duty motor blowing combined with a heat exchanger element usage, focusing on the method of implementing the heat exchanger space-efficient design and providing for reduction of resistance to the air flux. The heat exchanger is composed of the following components: a machine housing (1), an inner suction port (3) designed for indoor air (2) inlet, an inner diffuser (4), an outer suction port (7) designed for outdoor air (6) inlet, an outer diffuser (8), a motor (11) designed to be accommodated inside the machine housing (1), an inlet blade (9) and an outlet blade (10) mounted onto the engine (11), the casing (12) of the outlet blower designed as arranged inside the outlet blade (9), the casing (13) of the inlet blower designed as arranged inside the inlet blade (10) and multiple heat exchanger elements (16) arranged around the outlet blower casing (12) and the inlet blower casing (13).

EFFECT: reduction of the heat exchanger overall dimensions and weight and static pressure efficacy improvement.
