Description of Invention (6) A combination of manufactured parts. For example, a vehicle molded part is an air collector or a vehicle engine. Made of thermoplastic materials (for example, PA 66). In this state, the base member is a molded part of the vehicle, for example, an air collector or engine of the vehicle. Tortuous passage formed in - for example - on the inner molded part. -A sheet formed in a manner that promotes flow (i.e., has channels therein) is welded to a molded part by laser welding to form a conduit defined by channels and sheets in a molded part of a vehicle. The connection of the heat exchanger (ie, the inlet and outlet pipes) is formed as a part outside the molded part. In this manner is formed a collector integrated in the air manifold in a heat exchanger, and the matching of the manifold flow promoting three-dimensional shape. Since the fresh air from the engine manifold flows on the surface of the heat exchanger at high speed, a special cooling effect is produced in this condition. The cooling effect obtained can be used to cool the engine control electronics (for example, the electronics housing can be assembled in the same section). This embodiment illustrates one particular advantage of the present invention. By using a single piece, which has channels selectively, and the technical molding of an existing structural part (for example, an air collector) to serve as the base member of a heat exchanger, which has channels selectively, a high efficiency the heat exchanger may be provided in a very small space.
