HEAT EXCHANGER FOR AIRCRAFT Russian patent published in 2022 - IPC B64D33/10 B64C27/04 

FIELD: aviation.

SUBSTANCE: invention relates to heat exchangers for an aircraft, in particular, the heat exchanger is a gas-liquid heat exchanger. The heat exchanger for a transmission unit of an aircraft contains primary and secondary modules and the first row of ribs, lying on a plane orthogonal relatively to primary direction (X). The primary module defines a primary supply tract for primary fluid to be cooled. The secondary module defines a secondary supply tract for secondary cooling fluid. Primary and secondary supply tracts are in a heat contact with each other. Each secondary module contains a cell formed by an inlet for secondary cooling fluid; an outlet for secondary cooling fluid, which is placed on a side opposite to the inlet along the primary direction; a primary wall being in a heat contact with the primary tract; a couple of secondary walls; and a group of ribs protruding in the form of a console from the primary wall. At the same time, ribs of the first row protrude at increasing distances from one of secondary walls along secondary direction (Y) orthogonal relatively to primary direction (X).

EFFECT: obtaining a heat exchanger for an aircraft.
