Abstract:

One purpose of the present invention is to provide an EGR cooler wherein the cooling performance is improved by increasing the proportion of the volume of a core part performing heat exchange, and pressure-resistant strength is improved. An EGR cooler in which multiple flat tubes (4) for passing exhaust gas are stacked in the interior of a hollow-tube-shaped shell (7) and is connected thereto, and which comprises: a core part (1) for exchanging the heat between the exhaust gas and cooling water flowing around the tubes (4); a tubular inlet header (2) of which one end is connected to the shell (7) on the upstream of gas flow and which supplies the exhaust gas to the core part (1); and a tubular outlet header (3) of which one end is connected to the core part (1) on the downstream of the gas flow and which discharges the exhaust gas from the core part (1). The inlet header (2) and the outlet header (3) are connected to the outer surface of the shell (7), and the tubes (4) are connected to the inner surface of the shell (7) at the aforementioned connection parts (13).
