FIELD: power industry.
SUBSTANCE: heat exchanger includes casing with through openings on its opposite sides, phase transient working medium and heat carrier. Phase transient working medium is made in the form of frameless heat exchange elements from form-stable composite heat accumulating material, which are fixed inside casing with possibility of their being freely streamlined with heat carrier. In order to improve heat carrier to the space between adjacent heat exchange elements, elastic corrugated metal ribbed plates are installed. When using the heat exchanger as electric heating device, electric heaters are added to its composition.
EFFECT: improving mass and dimensions parameters of heat exchange devices at simultaneous increase of their power capacity, simplifying the design, increasing energy saving level and improving energy characteristics of the systems operating in peak actuation modes.
