Abstract

A combination exhaust gas heat exchanger and noise reduction unit is disclosed, whereby a heat exchanger and a noise reduction member are arranged side-by-side and integrated as a unit. A heat exchanger outlet opens directly into a chamber of the noise reduction member. In one arrangement, a bypass valve serves to selectively direct exhaust gas into either the heat exchanger or the noise reduction member, depending on an operating condition of an associated engine.

Description

technical field [0001] The present disclosure generally relates to an exhaust gas heat recovery device including a heat exchanger combined with a noise reduction member in a single unit. Background technique [0002] A conventional heat exchanger includes an exhaust passage through which exhaust gas passes, a coolant passage through which coolant passes, and a bypass passage which bypasses exhaust gas according to engine operating conditions. When the engine is running at low speeds, exhaust gas passes through the exhaust passage. However, when the engine is running at high speed, the exhaust gas passes through the bypass passage provided closer to the coolant passage than the exhaust passage. When the exhaust gas passes through the bypass passage, the exhaust gas is cooled by the coolant by transferring heat from the exhaust gas to the coolant. [0003] However, "heated" coolant can be used to preheat the engine and even the cabin. This is the so-called exhaust heat reco...
