That is, the inner wall portion 311 and the coupling portion 313 are coupled to the upper and lower ends of the coupling portion 313 so that the first welding point a and the second welding point b are formed.

상기한 상태에서, 외벽부(312)의 상단부가 결합부(313)의 하면과 밀착되도록 한 다음, 용접에 의해 외벽부(312)와 결합부(313)를 결합시킨다. 즉, 결합부(313)의 하면에 제3용접점(c)이 형성되도록 외벽부(312)와 결합부(313)를 결합시킨다.In the above state, the upper end portion of the outer wall portion 312 is brought into close contact with the lower surface of the coupling portion 313, and then the outer wall portion 312 and the coupling portion 313 are joined by welding. That is, the outer wall portion 312 and the coupling portion 313 are coupled to the third welding point c at the bottom surface of the coupling portion 313.

한편, 도 4를 참조하면, 내벽부(311)의 하단부 외주면에 결합부(313)를 밀착시킨 다음 용접에 의해 내벽부(311)와 결합부(313)를 결합시킨다. 즉, 결합부(313)의 상단부와 하단부에 제4용접점(d)과 제5용접점(e)이 형성되도록 내벽부(311)와 결합부(313)를 결합시킨다.Meanwhile, referring to FIG. 4, the coupling part 313 is brought into close contact with the outer circumferential surface of the lower end of the inner wall part 311, and then the inner wall part 311 and the coupling part 313 are coupled by welding. That is, the inner wall portion 311 and the coupling portion 313 are coupled to the upper and lower ends of the coupling portion 313 so that the fourth welding point d and the fifth welding point e are formed.

상기한 상태에서, 외벽부(312)의 하단부가 결합부(313)의 상면과 밀착되도록 한 다음, 용접에 의해 외벽부(312)와 결합부(313)를 결합시킨다. 즉, 결합부(313)의 상면에 제6용접점(f)이 형성되도록 외벽부(312)와 결합부(313)를 결합시킨다.In the above state, the lower end of the outer wall portion 312 is brought into close contact with the upper surface of the coupling portion 313, and then the outer wall portion 312 and the coupling portion 313 by welding.

상술한 케이스 부(31)의 결합관계에 의해, 내벽부(311)는 상단부나 하단부가 절곡되지 않으므로, 가스와의 접촉면적이 극대화되어 냉각효율이 향상된다.By the coupling relationship of the case part 31 described above, the inner wall part 311 does not bend the upper end part or the lower end part, so that the contact area with the gas is maximized, thereby improving the cooling efficiency.

그리고, 제1용접점 내지 제6용접점(a,b,c,d,e,f)이 내벽부(311)의 내측면, 보다 구체적으로 가스나 분진이 직접 접촉되는 부분에 위치되지 않기 때문에, 제1용접점 내지 제6용접점(a,b,c,d,e,f)은 가스나 분진에 의해 마모나 변형되지 않는다.In addition, since the first to sixth welding points (a, b, c, d, e, f) are not located on the inner surface of the inner wall portion 311, more specifically, the part where gas or dust is in direct contact. The first to sixth welding points a, b, c, d, e, and f are not worn or deformed by gas or dust.
