Title:
WASTE HEAT ENERGY REGENERATING METHOD AND WASTE HEAT ENERGY REGENERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2006/033182
Kind Code:
A1
Abstract:
Energy use efficiency of an engine is improved. Heat pipes (41a, 41b, 41c) are installed on an oil cooler (16a) for cooling operation oil increased in temperature by energy loss of a hydraulic circuit (25), on a radiator (16b) for cooling an engine coolant increased in temperature through cooling of an engine (11), and on an ATAAC (16c) for cooling engine suction air increased in temperature by being compressed by a turbocharger. The heat pipes (41a, 41b, 41c) absorb heat from the oil cooler (16a), radiator (16b), and ATAAC (16c) and evaporate a low boiling point medium. A turbine (24) for power recovery is mounted on the engine (11), and the turbine (24) is rotated by energy that the evaporated low boiling point medium has. A low boiling point medium circuit (38) is laid from the heat pipes (41a, 41b, 41c) of the oil cooler (16a), radiator (16b), and ATAAC (16c) across to the turbine (24). The low boiling point medium circuit (38) supplies the low boiling point medium evaporated by waste heat energy to the turbine (24) to drive it.
