HEAT STORAGE MODULE-HEAT EXCHANGER Russian patent published in 2023 - IPC F24H7/00 

FIELD: heat storage.

SUBSTANCE: invention relates to the storage of heat as a heat exchanger for generating electricity. The heat storage module-heat exchanger comprises a rectangular tubular body with end walls at the ends, filled with a heat storage composition made of a material with a changing phase state based on paraffins and a heat-conducting filler, inside which a heating element is built in the longitudinal direction. The housing (1) is made of metal and is additionally equipped with a Peltier thermoelectric element (6) forming an end wall at one end of the housing. The Peltier element is attached around the perimeter by means of a heat-conducting adhesive connection (7) with a heated surface facing the heat-storing composition (2, 3). As a heating element, there is a U-shaped branch pipe (5) intended for the flow of heated air in it as a heat carrier. The ends of the U-shaped branch pipe are united by soldering with the opposite end wall of the housing, which is a heating plate (4), equipped with two holes of different diameters, located coaxially with the holes of the U-shaped branch pipe. The inlet hole is made of smaller diameter. The inlet and outlet openings of the heating plate are connected with their respective flow slots (9, 10) made from the side of the heat source. The side faces of the housing are protected by thermal insulation (8), in particular from foamed rubber, and one of them has a pressure compensation valve (11).

EFFECT: expansion of functionality for the implementation of the generation of electrical energy and heat and mass transfer from a heat source to an object of the external environment is provided.
