Turbocharger water-cooled bearing housing.

摘要

A water-cooled turbocharger (l0) is fabricated employing a coreless die casting process. Instead of casting a complete passage in the bearing housing (l6) of the turbocharger (l0), an open ended channel (74) is cast into the housing (l6) and then sealed off by a mating seal plate (40). O-rings (76,78) or other sealing materials are used to seal the mating joints to prevent pressurized cooling water from leaking to the outside or into the internal bearing housing area.
