Abstract: An exhaust heat exchanger has a fin disposed in an exhaust passage in which exhaust air flows in a flow direction and having plate portions. The plate portions respectively have a protruding portion that protrudes from the plate portions. When a direction perpendicular to both the flow direction and a direction perpendicular to the flow direction is defined as a fin height direction, (i) a protruding amount of the protruding portion in a second site is larger than that in a first site, to which the second site is located on a downstream side of the first site in the flow direction, and (ii) a protruding amount of the protruding portion in a third site is larger than that in a fourth site, to which the fourth site is located away from a center portion of the protruding portion than the third site in the fin height direction.

Abstract: A method for manufacturing a heat exchanger includes: assembling a plurality of heat exchanger components in an assembly step; and forming a film on surfaces of the heat exchanger components using a chemical vapor deposition method in a film formation step after the assembly step. The film can restrict a formation of a through hole due to corrosion. The film can be restricted from being damaged at a delivery or assembling time, because the film formation step is provided after the assembly step. An occurrence of clogging can be restricted at a minute portion inside of the heat exchanger in the film formation step, because the film is formed using the chemical vapor deposition method.

Abstract translation: 制造热交换器的方法包括：在组装步骤中组装多个热交换器部件; 以及在组装步骤之后的成膜步骤中使用化学气相沉积法在热交换器部件的表面上形成膜。 该膜可以限制由于腐蚀形成的通孔。 由于在组装步骤之后提供成膜步骤，所以可以限制膜在输送或组装时间被损坏。 由于使用化学气相沉积法形成膜，所以在成膜步骤中可以在热交换器的内部的微小部分限制发生堵塞。
