VEHICLE POWER PLANT COOLING DEVICE Russian patent published in 2008 - IPC B60K11/00 F28D1/04 

FIELD: transport and agricultural engineering; power plant cooling systems.

SUBSTANCE: proposed device contains first heat exchanger designed for cooling first medium to be cooled by flow of external air passing through first front surface of first heat exchanger. Second heat exchanger of device is designed for cooling second medium to be cooled by flow of external air passing through second front surface of second heat exchanger. First heat exchanger contains inlet channel to supply first medium to be cooled, outlet channel to let out medium to be cooled and pack of tubular members arranged between two manifolds. First heat exchanger consists of two parts intercoupled by transition channel which are arranged so that front surfaces of each part are pointed towards external air flow and do not overlap. First part of second heat exchanger contains inlet channel to supply second medium to be cooled into second heat exchanger, and first pack of tubular members arranged between two manifolds of first part. Second part of second heat exchanger contains outlet channel to let out second medium to be cooled from second heat exchanger and second pack of tubular members arranged between two manifolds of second part. Each pack of tubular members of each exchanger is furnished with intertube corrugated attachments to form channel for passing external air. Tubular members in each pack are coupled by two supply members, one of which is in tight contact with one manifold, and the other is in tight contact with opposite manifold. Support members are rigidly coupled with pressure members and are made so that one end of each tubular member communicates with one manifold, and other end communicates with opposite manifold. First and second parts of second heat exchanger are arranged at sides of first heat exchanger so that front surfaces of first and second heat exchangers do not overlap. Tubular members of each pack are provided with intertube corrugated attachment to form channels for passing medium to be cooled.

EFFECT: reduced overall dimensions of cooling device, increased heat exchanger effectiveness.
