Targeted routing and control of the cooling water flow is required to achieve integrated thermal management on internal combustion engines. Thus, not only the cooling of the cylinder head and the crankcase is required, but also, among other aspects, the targeted temperature control of engine and transmission oil. In addition, the increasing use of water-cooled charge air coolers and turbochargers demands complex control, regulation and distribution systems for the coolant. Woco KKW produces water distributors made of plastic, some with built-in temperature sensors. The complex 3-dimensional geometries require advanced manufacturing, tooling and process technologies.
