HEAT EXCHANGER FOR AN EXHAUST GAS RECIRCULATION COOLER PERFORMANCE TEST, A THERMAL CYCLE TEST, AND AN ENGINE EXHAUST GAS SIMULATION, CAPABLE OF SUPPLYING AIR WITH HIGH TEMPERATURE TO THE EXHAUST GAS RECIRCULATION COOLER

摘要

PURPOSE: A heat exchanger for an exhaust gas recirculation(EGR) cooler performance test, a thermal cycle test, and an engine exhaust gas simulation are provided to heat air with high pressure to desired temperature in order to perform the tests.;CONSTITUTION: A heat exchanger(1) includes a main body(2), an external case(3), a coil pipe(4), and a heat-resistant block(5). A heat-resistant exhausting duct(22) is arranged on the upper side of the main body. A flame inducting pipe(232) is installed at the front part of the main body. The external case surrounds the external circumference of the main body. An insulating material and ceramic are stacked to from the external case.;COPYRIGHT KIPO 2011
