1. A heat exchanger comprising: a housing having a first opening at a first end and a second opening at an opposing second end;an exchanger region disposed in the housing with tubes that extend from the first opening to the second opening; andat least one base attached to the housing at either the first opening or the second opening,wherein ends of the tubes are connectable with the at least one base,wherein the housing is manufactured from a plastic material and has housing inner surfaces, andwherein the housing inner surfaces are covered at least in regions or in sections with at least one metallic element for protection of the housing from a thermal load,wherein the at least one metallic element extends into the housing starting from an edge of either the first opening or the second opening. 2. The heat exchanger according to claim 1, wherein a singular or a plurality of the at least one metallic element is provided on at least one of the housing inner surfaces, wherein the singular or the plurality of the at least one metallic element are molded into the plastic of the housing. 3. The heat exchanger according to claim 1, wherein an area receiving the at least one base and an area of the housing directly adjacent to the at least one base, has the at least one metallic element on one of the housing inner surfaces. 4. The heat exchanger according to claim 1, wherein the at least one metallic element has an annular cross section and outer surfaces of the metallic element simulate an inner surface of the housing. 5. The heat exchanger according to claim 1, wherein the at least one metallic element has an at least partially encircling angled edge region. 6. The heat exchanger according to claim 5, wherein the at least partially encircling angled edge region forms a stop against the housing. 7. The heat exchanger according to claim 1, wherein the at least one metallic element is formed in two parts, and wherein a division of the at least one metallic element into the two parts is produced by separating cuts on two opposite surfaces of the at least one metallic element. 8. The heat exchanger according to claim 1, wherein the at least one metallic element is an inlay. 9. The heat exchanger according to claim 8, wherein the inlay is formed in one piece or several pieces. 10. The heat exchanger according to claim 1, wherein the at least one metallic element is a metallic coating on at least one of the housing inner surfaces. 11. The heat exchanger according to claim 1, wherein the at least one metallic element completely covers the housing inner surfaces. 12. The heat exchanger according to claim 1, wherein the housing is a 2-component plastic part. 13. A method for producing a heat exchanger having an exchanger region with tubes which are flowed through by a fluid, a housing in which the exchanger region is arranged, the housing having a first opening at a first end and a second opening at an opposing second end, the tubes extending from the first opening to the second opening, and bases attached to the housing at the first opening and the second opening, respectively, the method comprising: covering, in a first method step, housing inner surfaces, at least in regions or in sections, with at least one metallic element so that the at least one metallic element extends into the housing starting from an edge of either the first opening or the second opening for protection of the housing from a thermal load;inserting at least one tube end of the tubes in a second method step in at least one of the bases; andproducing a non-releasable or solid tube-base connection in a second third method step with a connection technique. 14. The method according to claim 13, wherein the connection technique is a laser welding process. 15. A motor vehicle with at least one heat exchanger, which is produced by a method according to claim 13. 16. The heat exchanger according to claim 1, wherein the housing further includes a first flange region that surrounds the first opening at the first end and a second flange region that surrounds the second opening at the second end, wherein the at least one base includes a first base connected to the first flange region and a second base connected to the second flange region. 17. The heat exchanger according to claim 1, wherein the at least one base and the tubes are formed of metal. 18. The heat exchanger according to claim 7, wherein the separating cuts are provided at an angle to an axial direction of the tubes extending from the first opening to the second opening.
