Abstract: The present invention discloses a plate-fin structure EGR cooler with heat-insulation function includes shell. The two ends of the shell are equipped with an air inlet flange and a discharge chamber. A water inlet pipe and a water outlet pipe are set on the shell near the air inlet flange and the discharge chamber. A cooling core assembly, an air chamber and a bellow are set in the shell. The main board at one end of the cooling core assembly is connected to the shell and the discharge chamber and the main board at another end is connected to one end of the air chamber. The other end of the air chamber is connected to one end of the bellow. The other end of the bellow is connected to the shell and the air inlet flange. A heat-insulating pipe connected to the air inlet flange is set within the bellow.

Abstract: The present invention discloses an exhaust gas inlet structure of an exhaust gas recirculation (EGR) Cooler which includes a water shell, a gas inlet pipe, a bellow, an insulated pipe, an inlet chamber, a pre-cooling water chamber and a main board. The water shell is equipped with a water inlet pipe. Its main feature is the insulated pipe is placed within the bellow and connected with the gas inlet pipe at one end while the other end is suspended. The large-bore end of the inlet chamber is connected with the main board to form a gas inlet cavity while leaving a space to form a coolant channel between the joining part and the water shell. An external surface of a middle pipe body connects to the bellow to form a pre-cooling cavity connected to the coolant channel.
