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

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 in the form of a cylindrical ring, made of a closed sheet, bent to form a loop, the flat parts of the walls of which are located in the radial planes of the cylindrical body, inside the heat exchange matrix there is a displacer, consisting of a cylindrical shell and connected to it the edges of the diametrical and conical partitions, along the common axis of the cylindrical body and the heat exchange matrix, a tightening rod passes, which with its ends is detachably fixed in the thrust rings located in the inlet and outlet nozzles for the first coolant and rigidly connected to the nozzles by means of radial connections, on the cylindrical body distributing and collecting collectors are installed, covering the cylindrical body along its perimeter, the cavities of the distributing and collecting collectors are connected to the inlets and outlets of the channels for the second coolant through windows in the wall of the cylindrical body, the inlet and outlet nozzles for the second coolant are connected to the distributing and collecting collectors, respectively, in channels for the first coolant there are spacers connected to the displacer shell, sealing gaskets are placed between the ends of the heat exchange matrix and the covers, spacer rings are fixed on the inner surface of the cylindrical body, at least one end of the tightening rod is threaded and equipped with a spring dressed on the rod and located between the outer end edge of the thrust ring and the clamping nut, there are corrugations on the flat parts of the surfaces of the loop of the heat exchange matrix.

EFFECT: simplification of the design of the device, ability to produce a heat transfer surface from a single sheet.
