Vehicle exhaust gas recirculation cooler

A vehicle exhaust gas recirculation cooler comprising:

• a housing provided in a cylinder block located outside a water jacket of an internal combustion engine mounted in a vehicle and including a cooling fluid inlet and a cooling fluid outlet;
• a plurality of gas tubes disposed inside the housing and configuring an exhaust gas flow path;
• a tube plate including tube insertion holes to which opposing ends of the gas tubes are inserted and fixed;
• and
• a gas cover coupled to the housing on an outer side of the tube plate and including an exhaust gas inlet connected to one end of the gas tube and an exhaust gas outlet connected to the other end of the gas tube,
• wherein the cooling fluid inlet is provided adjacent to the cylinder block to receive a coolant flowing inside the cylinder block and supply the received coolant to the inside of the housing, and the cooling fluid outlet is provided on the gas cover and adjacent to the exhaust gas outlet,
• wherein the gas tube includes:
• a flat portion horizontally extending in a length direction of the housing;
• a first bent portion bent from one end of the flat portion to outside the housing;
• and a second bent portion bent from the other end of the flat portion to outside the housing, wherein the first and second bent portions are bent and rounded to have a predetermined curvature at opposing ends of the flat portion,
• wherein the tube plate includes a cooling fluid guide portion in which an inner side surface thereof at a portion corresponding to the flat portion protrudes toward the flat portion,
• wherein the cooling fluid guide part is formed such that a length thereof parallel to the tube plate is longer than a height thereof perpendicular to the tube plate, the height of the cooling fluid guide part being shorter than a distance between the tubes and the tube plate at an outermost position of the tubes toward the tube plate,
• further comprising:
• a sealing member provided between the tube plate and the gas cover.
