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: 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: An EGR cooler includes a heat exchanging core which has a plurality of tubes, an upstream-side gas tank portion upstream of the tubes and a downstream-side gas tank portion downstream of the tubes. A water tank portion forms a first water passage around the tubes and forms a second water passage around the upstream-side gas tank portion. A double pipe portion forms a gas passage which communicates with the upstream-side gas tank portion and forms an annular water passage which communicates with the second water passage. A water inflow pipe is connected to the double pipe portion such that the cooling water flows into the annular water passage, and a water outflow pipe that is connected to the water tank portion such that the cooling water flows out from the first water passage.
