Micro Channel Fuel Oil Heat Exchanger (PCHE)

The function of the fuel oil heat exchanger is to cool the lubricating oil and keep the oil temperature within the normal working range. On a high-power reinforced engine, an oil cooler must be installed due to the large thermal load. When the engine is running, the lubricating capacity is reduced due to the thinning of the oil viscosity with increasing temperature. Therefore, some engines are equipped with oil coolers, whose function is to reduce the temperature of the oil and maintain a certain viscosity of the lubricating oil. The role of the aerospace environmental control system is to reduce the temperature of the high-temperature air after supercharging, so as to reduce the thermal load of the engine, increase the intake air volume, and then increase the power of the engine
