종래 가스보일러의 열교환장치는 제1도에 도시되는 바와같이, 상부면에 배기덕트(1a)가 연통되는 외곽케이싱(1)의 중심부에 장착되며 점화플러그(2a)가 일정한 간격을 유지하며 설치되는 버너(2b)가 상부에 연통되고 분사노즐(2c)이 측벽부에 체결되는 송풍팬(2d)이 하부에 연통되는 혼합가스연소부(2)와, 이 혼합가스연소부(2)의 버너(2b) 주연부에 코일형상으로 설치되며 양단부에 난방수유입관(3a)과 난방수배출관(3b)이 연통되는 가열관부(3)와, 이 가열관부(3)의 상부면에 단열재(4a)가 장착되는 폐열차단판(4)이 설치되었다.As shown in FIG. 1, the heat exchanger of the conventional gas boiler is mounted at the center of the outer casing 1 in which the exhaust duct 1a communicates with the upper surface, and the spark plugs 2a are installed at regular intervals. The mixed gas combustion part 2 in which the blower 2b communicates with the upper part and the blowing fan 2d with which the injection nozzle 2c is fastened to the side wall part communicates with the lower part, and the burner of this mixed gas combustion part 2 2b) A heating tube portion 3 installed in a coil shape at the periphery and communicating with the heating water inlet pipe 3a and the heating water discharge pipe 3b at both ends thereof, and a heat insulating material 4a is attached to the upper surface of the heating tube portion 3. Waste heat shield plate 4 is installed.
이러한 종래 가스보일러의 열교환장치는 제1도에 도시되는 바와같이, 혼합가스연소부(2)의 하부에 연통되는 송풍팬(2d)에 의하여 외부공기가 흡입되고, 이 흡입되는 외부공기는 혼합가스연소부(2)의 측벽부에 체결되는 분사노즐(2c)를 통하여 유입되는 연료가스와 혼합되며, 이 혼합가스는 혼합가스연소부(2)의 상부에 연통되는 버너(2b)의 염공들을 통하여 외곽케이싱(1)의 내부에 유입되어 점화플러그(2a)의 점화불꽃에 의하여 연소되고, 이 고온의 연소가스는 혼합가스연소부(2)의 주연부를 감싸며 설치되는 가열관부(3)에서 열교환을 한 후에, 외곽케이싱(1)의 상부면에 연통되는 배기덕트(1a)를 통하여 외부로 배기되었다. 이때, 난방수유입관(3a)을 통하여 유입되는 난방수가 연소가스의 고온에 의하여 가열된 후에 난방수배출관(3b)을 통하여 배출되었다.In the heat exchanger of the conventional gas boiler, as shown in FIG. 1, the outside air is sucked by the blowing fan 2d communicating with the lower portion of the mixed gas combustion unit 2, and the sucked outside air is mixed gas. It is mixed with the fuel gas flowing through the injection nozzle (2c) is fastened to the side wall of the combustion unit 2, the mixed gas through the salt holes of the burner (2b) communicated to the upper portion of the mixed gas combustion unit (2) It enters the inside of the outer casing 1 and is burned by the ignition flame of the spark plug 2a, and this high-temperature combustion gas carries out heat exchange in the heating tube part 3 installed surrounding the periphery of the mixed gas combustion part 2. After that, it was exhausted to the outside through the exhaust duct 1a communicating with the upper surface of the outer casing 1. At this time, the heating water introduced through the heating water inlet pipe 3a was heated by the high temperature of the combustion gas and then discharged through the heating water discharge pipe 3b.

Due to the insufficient thermal insulation effect, the temperature of the waste heat shield plate gradually increased to increase the surface temperature of the system, and the heat efficiency was lowered because the waste heat of the combustion gas was not utilized due to insufficient heat exchange in the heating tube and exhausted to the outside. There was a problem.
