Claims

[Scope of utility model registration request]

A main body shell having an inlet duct on the lower side and an outlet duct on the upper side, at least one heat exchange section disposed in the main body shell at a position perpendicular to the flow of exhaust gas from the bottom to the top, A pair of headers provided at the inlet and outlet of the exchange section, and an exhaust gas passage section are defined on the inner surface of the main body located on both extension lines in the longitudinal direction of the heat exchanger tubes constituting the heat exchange section. The heat box and the exhaust gas passage are connected to each other by a communication pipe on the upstream side of the flow of exhaust gas, and through a hole in the partition plate on the downstream side of the exhaust gas flow. 1. An exhaust heat recovery heat exchanger characterized in that the through holes provided in the heat box communicate with each other so that the exhaust gas stagnant inside the heat box is drawn out to the exhaust gas passage side.
