Engine positive crankcase ventilation (PCV) system with a thermal management system including a heat pipe

摘要

The thermal management system includes a heat pipe 30 coupled between a heat source, such as, and one or more components of the PCV system 20. The heat source may be the cylinder head 22 of the engine, part of the exhaust system 50 or part of the engine cooling system 52. The heat pipe 30 may be configured to be in contact with a component, such as the PCV valve 26 or a hose 28, of the PCV system. The heat conveyed by the heat pipe 30 prevents freezing of the PCV system.
