이하 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail.

본 발명 온풍기(가)는 도 2와 도 3에서와 같이 내부에 여러 개의 방열기(1)가 설치되고 방열기(1)에 의하여 가열된 공기는 온풍기(가)의 상부 일측에 설치된 블로어(2)에 의하여 외부로 송풍되는 구성이다.2 and 3 of the present invention, the heat exchanger (a) has a plurality of radiators 1 installed therein, and the air heated by the radiator 1 is disposed on the blower 2 provided at an upper side of the heat blower (a). It is a configuration that is blown to the outside.

방열기(1)는 도 4에서와 같이 다수의 방열판(3)과 금속파이프(4)와 전기히터(5)로 구성된다. 본 발명의 실시예에서는 금속파이프(4)를 원통 형상으로 형성하고, 전기히터(5)를 봉체로 형성할 수 있다.The heat sink 1 is composed of a plurality of heat sink 3, the metal pipe 4 and the electric heater (5) as shown in FIG. In the embodiment of the present invention, the metal pipe 4 can be formed in a cylindrical shape, and the electric heater 5 can be formed in a rod.

방열판(3)은 얇은 철판으로 된 것으로서 도 6에서와 같이 금속파이프(4)에 끼우기 위한 통공(3a)이 뚫려있고 금속파이프(4)에 삽입된 후 방열판(3)의 유동을 방지하고 열전도가 잘되도록 하기 위한 플랜지부(3b)가 통공(3a)의 일측으로 일체로 돌출 형성되어 있다.The heat sink 3 is made of a thin iron plate, and as shown in FIG. 6, a through hole 3a is inserted into the metal pipe 4 and inserted into the metal pipe 4 to prevent flow of the heat sink 3 and prevent thermal conductivity. The flange portion 3b to be well formed is integrally projected to one side of the through hole 3a.

통공(3a)의 직경은 금속파이프(4)의 외경보다 약간 크게 한다.The diameter of the through hole 3a is made slightly larger than the outer diameter of the metal pipe 4.

방열판(3)에는 방열판(3)의 뒷면을 눌러 앞쪽으로 돌출하도록 한 여러 개의 방열편(3c)이 돌출하여 있다.A plurality of heat dissipation pieces 3c protrude from the heat sink 3 so as to protrude forward by pressing the rear surface of the heat sink 3.

방열편(3c)은 방열판(3)의 방열면적이 가능한 넓어지도록 하기 위한 것이다.The heat radiating piece 3c is for making the heat radiating area of the heat sink 3 as wide as possible.

방열판(3)에는 방열판(3)을 금속파이프(4)에 끼울 때 방열판(3)들이 원하는 간격으로 끼워지도록 하는 간격유지편(3d)이 절곡 돌출되어 있다.The heat dissipation plate 3 is bent and protruded from the heat dissipation piece 3d so that the heat dissipation plates 3 are inserted at a desired interval when the heat dissipation plate 3 is inserted into the metal pipe 4.

통공(3a)과 간격유지편(3d)을 이용하여 금속파이프(4)에 다수의 방열판(3)을 등간격으로 끼운 다음 통상의 파이프 확관기를 사용하여 금속파이프(4)를 확관시키므로서 금속파이프(4) 외면에 방열판(3)의 플랜지부(3b)가 견고하게 밀착되고 방열판(3)이 고정된다.A plurality of heat sinks 3 are inserted into the metal pipe 4 at equal intervals using the through hole 3a and the space keeping piece 3d, and then the metal pipe 4 is expanded by using a common pipe expander. The flange portion 3b of the heat sink 3 is firmly adhered to the outer surface of the pipe 4 and the heat sink 3 is fixed.

금속파이프(4)의 확관에 의한 금속파이프(4)와 방열판(3)의 밀착은 견고하고 강력한 것이므로 가열과 냉각과정에서 쉽게 이완되지 아니한다.The close contact between the metal pipe 4 and the heat sink 3 by the expansion of the metal pipe 4 is a strong and strong one, and thus it is not easily relaxed during the heating and cooling process.

본 발명 금속파이프(4)는 열전도가 잘되고 녹쓸지 아니하는 스테인레스 파이프로 하는 것이 바람직하다.The metal pipe 4 of the present invention is preferably made of a stainless pipe that has good thermal conductivity and does not rust.

여러개의 방열판(3)이 등간격으로 밀착설치된 금속파이프(4) 내에 전기히터(5)를 삽입하므로서 방열기(1)가 완성된다.The radiator 1 is completed by inserting the electric heater 5 into the metal pipe 4 in which several heat sinks 3 are closely spaced at equal intervals.

상기와 같은 구성으로 된 방열기(1)는 전기히터 외면에 방열판을 나선형으로 감아 고정시키는 것에 비하여 제작이 용이하여 생산성이 높고 불량율이 낮다.The heat dissipator 1 having the above-described configuration is easy to manufacture compared to fixing the heat dissipation spirally on the outer surface of the electric heater, and thus has high productivity and low defect rate.

또한 방열판(3)의 밀착도가 높아 열전도율이 높고 금속파이프(4)에 등간격으로 설치된 다수의 방열판(3)은 전기히터(5)로부터 전달되는 고열을 온풍기(가) 내에 고르게 분산 방열하고 방열면적이 넓어 신속한 방열이 가능하다.In addition, the heat dissipation 3 has a high thermal conductivity and high heat conductivity, and a plurality of heat dissipation plates 3 installed at equal intervals on the metal pipe 4 evenly disperse and dissipate high heat transmitted from the electric heater 5 in the hot air heater. This wide range enables rapid heat dissipation.

고른 발열은 온풍기의 송풍온도가 고르게 되도록 하고 신속한 방열은 열에너지를 절감한다.Even heat generation ensures that the blowing temperature of the hot air fan is even and rapid heat dissipation saves heat energy.

방열기(1)는 도 3에서와 같이 온풍기(가)내의 벽체(6)에 뚫어 놓은 구멍에 금속파이프(4)를 삽입하고 용접 고정하는 방법으로 설치한다.
As shown in FIG. 3, the radiator 1 is installed by inserting the metal pipe 4 into the hole drilled in the wall 6 in the hot air heater A and welding and fixing it.

전기히터(5)의 외경은 금속파이프(4)에 삽입이 용이하게 이루어지면서 쉽게 빠져나오지 않도록 약간 빡빡하게 삽입되는 정도의 크기이다.The outer diameter of the electric heater (5) is such that the insertion into the metal pipe (4) is made to be a bit tight enough to not easily come out.

전기히터(5)와 금속파이프(4)는 냉각된 상태에서 완전 밀착되지 아니하도록 하는 약간의 유격을 가지나 전기히터(5)에 전기를 인가하면 전기히터(5)가 발열하고 약간 팽창되어 금속파이프(4)와 완전히 밀착하므로 열전도에 문제가 없다.The electric heater 5 and the metal pipe 4 have a slight clearance so that they do not come into close contact with each other in a cooled state, but when electricity is applied to the electric heater 5, the electric heater 5 generates heat and slightly expands, so that the metal pipe Since it adheres completely with (4), there is no problem with heat conduction.

온풍기(가)의 온도는 방열판(3)을 관통하여 설치된 써미스터(7)와 써미스터(7)와 연결된 온도조절기(8)에 의하여 조절되고 적절히 가열된 온풍기(가) 내의 공기는 모터(9)와 송풍팬(10)과 공기배출로(11)로 구성된 블로어(2)에 의하여 외부로 배출된다.The temperature of the hot air heater (a) is controlled by the thermistor (7) installed through the heat sink (3) and the temperature controller (8) connected to the thermistor (7), and the air in the hot air heater (a), which is properly heated, is connected to the motor (9). It is discharged to the outside by the blower (2) consisting of the blowing fan 10 and the air discharge path (11).
