The present invention relates to an exhaust gas cooling apparatus and, more specifically, to an exhaust gas cooling apparatus capable of reducing flow resistance and improving heat exchange performance, the apparatus comprising: a plurality of heat exchange tubes (200), which is spaced apart from each other by a predetermined distance in the width direction and has a height longer than the width, and through which an exhaust gas flows; and a main plate (300) including a first communication hole (310) to which one end of each of the heat exchange tubes (200) is fixed and a second communication hole (320) to which the other end of each of the heat exchange tubes (200) is fixed. La présente invention concerne un appareil de refroidissement des gaz d'échappement et concerne, plus précisément, un appareil de refroidissement des gaz d'échappement pouvant réduire la résistance à l'écoulement et améliorer les performances d'échange de chaleur. L'appareil de refroidissement des gaz d'échappement comprend : plusieurs tubes d'échange de chaleur (200), espacés les uns des autres par une distance prédéfinie dans le sens de la largeur et ayant une hauteur qui est plus longue que la largeur, par lesquels s'écoule un gaz d'échappement ; et une plaque principale (300) comprenant un premier trou de communication (310) auquel est fixée une extrémité de chacun des tubes d'échange de chaleur (200) et un second trou de communication (320) auquel est fixée l'autre extrémité de chacun des tubes d'échange de chaleur (200). 본 발명은 배기가스 냉각장치에 관한 것으로, 더욱 상세하게 폭방향으로 일정간격 이격되어 배치되며, 폭 대비 높이가 높게 형성되고, 내부에 배기가스가 흐르는 복수 개의 열교환관(200) 및 상기 열교환관(200)의 일단이 고정되는 제1연통홀(310)과 상기 열교환관(200)의 타단이 고정되는 제2연통홀(320)을 포함하는 메인플레이트(300)를 포함하여, 유동저항을 줄이고, 열교환 성능을 향상시킬 수 있는 배기가스 냉각장치에 관한 것이다.
