The present invention relates to a turbocharger capable of cooling an exhaust system, to supply a part of air compressed and discharged from the turbocharger to the exhaust system in order to prevent overheat of the exhaust system, and an exhaust system cooling system using the same. According to the present invention, the turbocharger capable of cooling an exhaust system allows a turbine (21) rotated by exhaust gas to operate a compressor (22) to compress and discharge the air supplied to an engine (1). The turbocharger comprises: a protector (42) having an inner surface spaced apart from the surface of a post-treatment device (23) to surround the post-treatment device (23) for purifying the exhaust gas; and a cold wind flowing pipe (41) to connect the compressor (22) with the protector (42). 본 발명은 배기계가 과열되는 현상이 방지되도록 터보차저에서 압축되어 토출되는 공기의 일부를 배기계로 공급되도록 하는 배기계를 냉각시킬 수 있는 터보차저 및 이를 이용한 배기계 냉각시스템에 관한 것이다. 본 발명에 따른 배기계를 냉각시킬 수 있는 터보차저는, 배기가스에 의해 회전하는 터빈(21)이 컴프레서(22)를 구동시켜 엔진(1)으로 유입되는 공기를 압축시켜 토출시키는 터보차저에 있어서, 배기가스를 정화시키는 후처리장치(23)를 감싸도록, 내측면이 상기 후처리장치(23)의 표면과 이격되게 형성되는 프로텍터(42)와, 상기 컴프레서(22)와 상기 프로텍터(42)를 연결하는 냉각풍 유동관(41)을 포함한다.
