FLAP HEAT EXCHANGER Russian patent published in 2023 - IPC F28D9/00 F28D9/02 F28F1/00 F28F1/06 

FIELD: heat engineering.

SUBSTANCE: invention can be used in recuperative heat exchange devices. The invention lies in the fact that the heat exchanger has a heat exchange matrix made in the form of a cylindrical ring made of a closed sheet, bent to form loops, the flat parts of the walls of which are oriented along the radial directions of the cylindrical body, in the central part of the heat exchange matrix there is a fairing, including a cylindrical shell and diametrical and conical baffles connected to it by edges, a rod having a common axis with a cylindrical body and a heat exchange matrix is connected to the fairing at one end, the other end of the rod is fixed in a sleeve, which is connected with the wall of the branch pipe for the first coolant by means of radial spokes, on the outer surface At least two rows of spacer spikes are installed on the fairing shell, the tops of which enter the channels for the first coolant, spacer rings are fixed on the inner surface of the cylindrical body, sealing gaskets are placed between the ends of the heat exchange matrix and the covers, the inlet and outlet pipes for the second coolant are installed on the distributing and collecting collectors, respectively, which are connected to the cylindrical body and cover it along the perimeter, there are corrugations on the flat parts of the surfaces of the loops of the heat exchange matrix.

EFFECT: simplification of the design of the device, ability to manufacture a heat exchange matrix from a single sheet.
