Exchanger element for a vehicle and vehicle equipped with such an exchanger element

Abstract

The invention relates to an exchanger element (1) for use on board a vehicle, in particular for a passenger compartment and/or the engine bay of a vehicle. The exchanger element has an exhaust air flow path (2) and a feed air flow path (3), wherein the exhaust air flow path and the feed air flow path are separated from one another by partition sections that have heat-transmitting wall regions. The exhaust air flow path (2) forms a fluid connection from the interior of the vehicle to the outer surroundings of the vehicle. The feed air flow path (3) forms a fluid connection from the outer surroundings of the vehicle to a location on board the vehicle. According to the invention, the exchanger element (1) is embedded in a package (4), the outer surface area shape of which matches the inner dimensions of an installation space on board the vehicle for the installation of the exchanger element (1).
