The heat exchanger is provided with a top plate (210), two walls (221, 222) and two ridge line parts (231, 232). The tensile strength of the top plate (210) and the walls (221, 222) is 1470 MPa or more; the two ridge portions (231, 232) extend in the longitudinal direction of the top plate (210) between the top plate (210) and the walls (221, 222), respectively. The cross section of the central part in the length direction is a groove-shaped opening cross section; in a cross section, the top plate (210) is provided with a central groove portion (260) extending in the longitudinal direction at the center of the width; in a cross section, the top plate (210) is provided with small groove portions between the central groove portion (260) and the ridge line portions (231, 232). In a cross section, the depth of the groove located in the center is more than 15 times and less than 25 times of the plate thickness of the top plate (210). The depth of the small groove parts (240, 250) is more than 2 times and less than 13 times of the plate thickness of the top plate (210); the interval between the small groove parts (240, 250) and the ridge parts (231, 232) is 30 times or less of the plate thickness of the top plate (210).

    具备顶板(210)、两个壁(221、222)和两条棱线部(231、232);顶板(210)和壁(221、222)的抗拉强度为1470MPa以上;两条棱线部(231、232)分别在顶板(210)与壁(221、222)之间在顶板(210)的长度方向上延伸;长度方向的中央部的横截面为槽形的开口截面;在横截面中,顶板(210)在宽度的中央具备在长度方向上延伸的中央槽部(260);在横截面中,顶板(210)在中央槽部(260)与棱线部(231、232)之间分别具备小槽部;在横截面中,处于中央的槽的深度为顶板(210)的板厚的15倍以上25倍以下;小槽部(240、250)的深度为顶板(210)的板厚的2倍以上13倍以下;小槽部(240、250)与棱线部(231、232)的间隔为顶板(210)的板厚的30倍以下。
