交換器を提供できる。According to the heat exchanger of the present invention, a cap-shaped end cover 2 is fitted to the outer periphery of the open end of a cylindrical tank body 1, and a small recess formed from the edge thereof. 8 has a structure in which the locking piece 7 of the side member 6 is fitted, so that the end member 2 can be attached to the open end of the tank body 1 and the side member 6 can be held on the side surface of the core 5 at the same time. Therefore, the assembly is quick and easy, and the heat exchanger assembly can be directly inserted into the furnace and the components can be integrally brazed and fixed. At the same time, since the cap-type end cover 2 is used, it is possible to reliably braze the tank body 1 and the end cover 2 between them and the end of the side member 6 while maintaining the liquid tightness. It becomes possible. According to the second aspect of the present invention, since the width B of the small concave portion 8 of the end cover 2 is formed to be narrower than the fitting allowance C of the end cover 2, the tank body 1 and the end are more reliably connected. It is possible to reliably braze the locking piece 7, the end cover 2, and the tank body 1 while improving the liquid tightness of the cover 2. In addition, a highly reliable heat exchanger with good mass productivity can be provided.
