FIELD: heating.
SUBSTANCE: heat exchanger is offered which consists of the housing with supply and discharge heat carrier branch pipes. Along the heat exchanger axis the units of heat exchange elements with two peripheral distributive headers of the second heat carrier forming peripheral and axial headers of the first heat carrier are installed. Each of heat exchange elements is made hollow with odd amount of radial cuts where the transversal partitions are arranged, while walls of heat exchange elements have radially directed spacing ledges from one of the sides which alternately form in the external cavity the slot-hole channels for the first heat carrier, and in the internal cavity - for the second heat carrier.
EFFECT: design simplification, avoidance of requirements to configuration, increase of average temperature head.
