EXHAUST HEAT RECOVERY SYSTEM

摘要

An exhaust heat recovery system (18) includes first and second loop heat pipes (20 and 30). The first loop heat pipe (20) recovers exhaust heat downstream of a catalyst (5) in an exhaust passage (4) of an internal combustion engine (1) to exchange heat with the catalyst (5). The second loop heat pipe (30) recovers heat of the catalyst (5) to exchange heat with coolant that is once delivered from the internal combustion engine (1).
