2중관(2) 중 외관(20)을 중심으로 내,외부에 각각 위치하게 되는 내관(22) 및 외측공간(70)에 있어서, 외관유로부(5), 내관유로부(3) 및 외관외측유로부(7)에 대하여 각각 살펴보기로 한다.In the inner tube (22) and the outer space (70), which are located inside and outside the center (2) of the double pipe (2), respectively, the exterior flow passage portion (5), the inner tube flow passage portion (3) and the exterior exterior portion. Each of the flow path portions 7 will be described.

첫째, 외관유로부(5)의 저온유체 유입구(62)를 거쳐 유입된 저온유체가 제2우측격실(56)에 마련된 제2수평구획판(58)의 상부에 위치한 제2상부격실(60), 상부 외관(20), 제2좌측격실(54)에서 방향전환, 하부 외관(20), 제2우측격실(56)에 마련된 제2수평구획판(58)의 하부에 위치한 제2하부격실(64), 그리고 저온유체 배출구(66)를 거쳐 배출된다.First, the second upper compartment 60 located at the upper portion of the second horizontal partition plate 58 provided with the low temperature fluid introduced through the low temperature fluid inlet 62 of the exterior flow path part 5 is provided in the second right compartment 56. The second lower compartment located below the second horizontal partition plate 58 provided in the upper exterior 20, the second left compartment 54, and the lower exterior 20, the second right compartment 56. 64), and is discharged through the low temperature fluid outlet (66).

둘째, 이와 같이 저온유체가 외관유로부(5)를 경유하여 통과하게 되는 동안, 동시에 외관유로부(5)의 내측에 위치하게 되는 내관(22)에 있어서 내관유로부(3)의 경우엔 고온유체유입구(42)를 거쳐 유입된 고온유체가 제1좌측격실(34)에 마련된 제1수평구획판(38)의 상부에 위치한 제1상부격실(40), 상부 내관(22), 제1우측격실(36)에서 방향전환, 하부 내관(22), 제1좌측격실(34)에 마련된 제1수평구획판(38)의 하부에 위치한 제1하부격실(44), 그리고 고온유체배출구(46)를 경유하여 배출된다.Second, while the low-temperature fluid passes through the outer channel part 5 in this way, in the inner tube 22 which is located inside the outer channel part 5 at the same time, in the case of the inner tube channel part 3, The first upper compartment 40, the upper inner tube 22, and the first right side of the first upper compartment 40 positioned at the upper portion of the first horizontal partition plate 38 provided in the first left compartment 34 through which the high temperature fluid introduced through the fluid inlet 42 is provided. Changing direction from the compartment 36, the lower inner tube 22, the first lower compartment 44 located below the first horizontal partition plate 38 provided in the first left compartment 34, and the hot fluid outlet 46 Discharged via

셋째, 위와 같이 저온유체가 외관유로부(5)를 경유하여 통과하고, 동시에 고온유체는 내관유로부(3)를 경유하여 통과하며, 이와 동시에 고온유체는 외관외측유로부(7)에도 통과하게 되는데, 즉 고온유체유입구(72)를 경유하여 유입된 고온유체는 외관(20)의 외측에 위치하게 되는 외측공간(70)을 경유하여 이동하되 다수의 상,하부에 교번적으로 설치된 배플(76)에 의하여 지그재그로 방향전환이 이루어지면서 이동하여 고온유체배출구(74)를 거쳐 외부로 배출된다.Third, as described above, the low-temperature fluid passes through the outer channel part 5, and at the same time, the high-temperature fluid passes through the inner tube channel part 3, and at the same time, the high temperature fluid also passes through the outer channel part 7 at the same time.

Only the outer space 70 positioned outside the double pipe 2 is formed in communication with each other at a position adjacent to the inside of the second left and right compartments 54 and 56 of the exterior flow passage part 5 and the outer cylinder 1 On both sides of the) is provided a hot fluid inlet 72 and a hot fluid discharge port 74 in communication with the outer space 70 at each end, and between the hot fluid inlet 72 and the hot fluid outlet (74) A plurality of baffles 76 are alternately installed at the upper and lower positions, so that the high temperature fluid supplied to the high temperature fluid inlet 72 passes through the inside of the outer space 70 as a outside of the exterior 20 and then zigzags to the high temperature fluid. Heat exchanger, characterized in that the configuration is made by forming the outer appearance of the outer flow path portion (7) to be discharged via the discharge port (74).
