PURPOSE: A passage resistance control-type condenser is provided to reduce the number of the passing times via a special bypass pipe with a solenoid valve when passage resistance increases by installing pressure sensors to the inlet side and the outlet side, and to improve the radiating performance by differentiating the number of the passing times according to the passage resistance. CONSTITUTION: A passage resistance control-type condenser comprises a pair of header pipes(1a,1b) arranged in parallel; plural tubes(3) connecting the header pipes; and cooling fins(4) filled between the tubes. The passage resistance control-type condenser has a passage formed in zigzags along the tubes by baffles(2) disposed to the inside of the header pipes. The passage resistance control-type condenser has a first pressure sensor(5) and a second pressure sensor(6) to a refrigerant inlet pip(11) and a refrigerant outflow pipe(12). A bypass pipe(13) is connected to the middle of the header pipes from the refrigerant inlet pip and a solenoid valve(7) is disposed in the middle of the bypass pipe. The passage resistance control-type condenser varies the passage of the inside of the condenser by opening and shutting the solenoid valve according to a pressure difference of the pressure sensors.
