EGR COOLER

摘要

PURPOSE: A cooler for exhaust gas re-circulating device is provided to prevent damage to a thermoelectric module by dispersing coherence by installing a bolt along with a thermal stress absorption member. CONSTITUTION: A cooler for exhaust gas re-circulating device comprises an exhaust gas pipe(140), first and second cooling plates(110,120), and a third cooling plate. A first thermoelectric module(150) and a second thermoelectric module(152) are attached to one side of the other side of the exhaust gas pipe, respectively. A first heat radiation fin is attached to the one inside of the exhaust gas pipe. The first heat radiation fin of the exhaust gas pipe has a separate space in which the second heat radiation fin is attached. The first and the second cooling plate respectively heat-exchange with the first thermoelectric module and the second thermoelectric module using the cooling water as medium.
