Heat exchanger with corrosion reducing sacrificial component

A heat exchanger for exchanging heat between a first fluid and a second fluid, the heat exchanger comprising:

• a first manifold and a second manifold,
• a bundle of heat exchange elements for the first fluid axially extending and providing a fluidal communication between the first and second manifolds,
• a housing for the second fluid encapsulating at least part of the heat exchange elements to form a fluid tight channel for the second fluid,
• wherein the housing includes at least one sacrificial component being of material having lower galvanic potential than the remaining components, the sacrificial component being a plate that includes at least one opening;
• wherein the sacrificial component includes at least one recessed section extending from a median section of the shorter side thereof and at least a pair of projections located on opposite ends of the shorter side thereof, on each side of the at least one recessed section.
