Heat exchanger for an air conditioner of a motor vehicle and method for producing the same

Abstract

A heat exchanger for an air conditioner of a motor vehicle is provided. The heat exchanger has at least one pipe for guiding a fluid and air conduction component arranged adjacent to the at least one pipe for conducting an air flow to flow around the at least one pipe. The air conduction component thereby has at least one separating section, which is embodied to separate the air flow into a first partial air flow and a second partial air flow. The at least one separating section is formed by an adhesive applied to the air conduction component, wherein the adhesive contains a volume-increasing component for increasing a volume of the adhesive.
