Abstract
An aircraft includes a heat exchanger between, on the one hand, a first fluid that flows into the narrow pipes (22) of the exchanger and that is able to contain solid elements that can melt, and, on the other hand, a second fluid to be cooled. The heat exchanger includes a device for preheating the first fluid upstream from the pipes (22) of the exchanger, a number of pipes arranged in at least one plane that is secant to the direction of flow of the first fluid, whereby the spacing between two adjacent pipes is suitable for retaining the solid elements of large dimensions and for allowing them to pass only when they have melted at least partially.
