PURPOSE: An inverter oil cooler with a coolant pressure stabilizing apparatus is provided to minimize the stand-by time of the inverter compressor within two seconds by keeping high and low pressures of coolant uniform. CONSTITUTION: An inverter oil cooler comprises a plate evaporator(10) which cools oil, an inverter compressor(20) in which vaporized coolant of low temperature and low pressure flows in through a CFC transfer pipe(11) and compressed to high temperature and high pressure, a coolant pressure stabilizing device(30), a condenser(40) which radiates the high temperature and high pressure coolant by a fan(50) driven by a motor(M), a drier(60) through which the condensed liquid coolant passes, and an electronic expansion valve(70) which discharges the liquid coolant of low temperature and low pressure by controlling sensor channels of an exterior temperature sensor(41), a coolant low pressure sensor(12), and oil inlet and outlet sensors(1,1'). The discharged liquid coolant of low temperature and low pressure is transferred to a jet evaporator to cool down oil.
