Title:
EXHAUST GAS COOLER
Document Type and Number:
WIPO Patent Application WO/2017/073895
Kind Code:
A1
Abstract:
The present invention relates to an exhaust gas cooler comprising: a heat exchange pipe received in a cooling water of an engine, wherein an exhaust gas of the engine that exchanges heat with the cooling water passes through the heat exchange pipe; and a plate for mounting the heat exchange pipe in the engine, wherein the heat exchange pipe includes: a first pipe communicating with a supply port for the exhaust gas; a second pipe communicating with the first pipe and guiding the exhaust gas, which is introduced from the first pipe, in one direction; and a third pipe communicating with a recovery port for the exhaust gas and the second pipe and changing the direction of the exhaust gas introduced from the second pipe to guide the same to the recovery port, wherein a heat dissipation fin is formed in the internal flow passage of the second pipe. Accordingly, the flow passage for the exhaust gas passing through the heat exchange pipe increases in length and smoothly turns in the limited space, which makes it possible to reduce a pressure drop of the exhaust gas and to increase the heat exchange area of the exhaust gas. Thus, heat exchange efficiency can be enhanced in the limited space.
