For performance test of oil cooler, we manufactured a test equipment which can heat oil up to the test temperature and supply it continuously to be tested object. This test equipment was composed of 300,000 Kcal/h steam boiler and 300,000 Kcal/h plate type heat exchanger, and this can do real time control the test conditions by the method which high temperature water heats the outlet cooled oil after test. For many different size oil coolers, by use of this equipment, we evaluated the heat exchange performance of oil coolers and pressure drop characteristics in side of oil and cooling water according to flow variation. Besides, we also estimated temperature characteristics of oil coolers.
