Preferably, the projection band formed in any one of the first cooling water pipe 30 or the second cooling water pipe 40 is formed to be in contact with the other cooling water pipe is not formed with the projection band is the flow of exhaust gas At the same time to improve the efficiency, the first and second cooling water pipes (30, 40) are in contact with each other to improve the durability performance of the vibration of the vehicle.

여기서, 상기 돌출띠는 상기 제1냉각수관(30) 또는 제2냉각수관(40) 중 어느 하나와 일체로 형성되는 것이 바람직하나, 별도로 부착하여 형성시키는 것도 가능하다.Here, the protrusion band is preferably formed integrally with any one of the first cooling water pipe 30 or the second cooling water pipe 40, it is also possible to form separately attached.

또한, 상기 돌출띠의 재질은 배기가스의 열에 견딜 수 있는 어떤 재질이라도 가능함을 밝혀둔다.In addition, it is noted that the material of the protruding band may be any material capable of withstanding the heat of the exhaust gas.

본 발명의 자동차 배기구의 배기열 회수장치와 종래의 배기열 회수장치를 비교하여 살펴보면, 도 1에 도시된 바와 같이 종래에는 배기가스가 바이패스관(100)의 통공을 통해 하우징(200) 내부로 인입되어 상기 바이패스관(100)과 제2냉각수관(400)의 사이를 이동하게 되고, 이후 상기 제1냉각수관(300)과 제2냉각수관(400) 사이를 이동하면서 상기 제1,2냉각수관(300,400) 내부의 냉각수와 열교환하면서 배출되게 되는데, 이때 상기 제1,2냉각수관(300,400) 사이로 직진하여 배출됨으로 인해 열교환시간이 짧아 냉각수 및 변속기오일의 충분한 웜업 효과를 기대할 수 없었다.When comparing the exhaust heat recovery apparatus of the vehicle exhaust port and the conventional exhaust heat recovery apparatus of the present invention, as shown in Figure 1, the exhaust gas is conventionally introduced into the housing 200 through the through-hole of the bypass pipe (100) The first and second cooling water pipes are moved between the bypass pipe 100 and the second cooling water pipe 400, and then moved between the first cooling water pipe 300 and the second cooling water pipe 400. It is discharged while exchanging heat with the cooling water (300,400), in which case the heat exchange time is short due to the discharge straight through the first and second cooling water pipes (300,400) could not be expected a sufficient warm-up effect of the cooling water and transmission oil.

그러나, 본 발명의 자동차 배기구의 배기열 회수장치는 제1냉각수관(30)과 제2냉각수관(40)의 사이에 회류유도구(61)를 형성시켜 된 배기가스 유도로(60)를 포함함으로써, 배기가스를 스크루 형태로 회류시켜 배출하게 되고, 이에 따라 배기가스와 냉각수 및 변속기오일과의 열교환 시간을 증가시켜 열교환 효율을 높이도록 한 것이다. However, the exhaust heat recovery apparatus of the automobile exhaust port of the present invention includes the exhaust gas induction furnace 60 formed by forming the circulating oil tool 61 between the first cooling water pipe 30 and the second cooling water pipe 40. In addition, the exhaust gas is discharged by rotating in the form of a screw, thereby increasing the heat exchange time between the exhaust gas, the cooling water, and the transmission oil, thereby increasing the heat exchange efficiency.

한편, 본 발명에 따른 자동차 배기구의 배기열 회수장치는 상술한 바와 같은 구체적인 실시예 및 첨부한 도면을 참조하여 설명하였으나, 이는 본 발명이 속하는 기술 분야에서 통상의 지식을 가진자가 발명을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로 인해 본 발명의 기술적인 사상 및 범주가 한정되는 것을 의미하지는 않는다.
On the other hand, the exhaust heat recovery apparatus of the automobile exhaust outlet according to the present invention has been described with reference to the specific embodiments as described above and the accompanying drawings, which can be easily implemented by those of ordinary skill in the art. It is intended to be described in detail as much as possible, which does not mean that the technical spirit and scope of the present invention are limited.
