STRUCRURE FOR REMOVING THE CONDENSATION WATER OF EXHAUST GAS RECIRCULATION IN DIESEL ENGINE SYSTEM AND METHOD THEREOF

摘要

PURPOSE: A structure and method for removing the condensation water in the exhaust gas recirculation device of a diesel engine system is provided to remove the condensation water on a surface of a cooling pipe by passing through a gap of cooling pipes and the flow of the exhaust gas changed into high speed. CONSTITUTION: A structure for removing the condensation water in the exhaust gas recirculation device of a diesel engine system(100) comprises an EGR cooler and a plurality of cooling pipes(120). The EGR cooler has a heat exchanger(110). The heat exchanger is installed in the middle of a low-pressure exhaust gas circulating pipe(35) installed between an exhaust pipe(50) and an intake pipe(40). The heat exchanger guides the low pressure exhaust gas in one direction. A plurality of cooling pipes is installed in the internal space of the heat exchanger. A plurality of cooling pipes contacts with the low-pressure exhaust gas with being placed across the flow of the low-pressure exhaust gas and the cooling pipe guides the cooling water in one direction.
