Cooling-water based aggregate unit for vehicle cooling circuit, has leakage reservoir consisting of compound environment including semi-permeable membrane, dye filter or anti-freeze filter

摘要

The aggregate unit includes a leading space, a seal, and a cool water-bearing room in which a leakage line is formed remotely from the seal which prevents the leakage of cooling water. A leakage reservoir is operatively connected to the leakage line. The leakage reservoir consists of a compound environment including a semi-permeable membrane, a dye filter or an anti-freeze filter.
