HEAT EXCHANGER HAVING AIR EXHAUST MEMBER

摘要

PURPOSE: A heat exchanger is provided to smoothly flow heating water by frequently exhausting the air generated from a heat exchanger to outside. CONSTITUTION: An air contained in heating water flowing in a pipe(17) is collected if the heat generated from a gas burner is continuously pressurized at a high temperature. A female screw unit of a cap(60) is separated from a male screw unit(54) of an exhaust pipe(52) if a user revolves the cap with hands. Internal air is exhausted to outside as the air flowing along a pipe(17) through the exhaust pipe is exhausted to outside. Then, the cap is tightened to the exhaust pipe by connecting the female screw unit to the male screw unit. Also, the heating water and air is isolated through the exhaust pipe as a sealing ring(64) is adhered.
