摘要： 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. The advantages of the present invention are as follow: newly-added pre-cooling water chamber reduces the wall temperature of the main board and the inlet chamber; newly-added supporting in the middle part of the insulated pipe improves the vibration-proof function of the insulated pipe; the special structure of the inlet chamber increases the ability of the axial displacement compensation. The above-mentioned improvement of the present invention significantly improves the reliability of the EGR cooler.
摘要翻译：本发明公开了一种废气再循环（EGR）冷却器的排气入口结构，其包括水壳，进气管，波纹管，绝缘管，入口室，预冷水室和主板。水壳配有进水管。其主要特点是绝缘管放置在波纹管内，一端与进气管连接，另一端悬吊。入口室的大口端与主板连接以形成气体入口腔，同时留下空间以在接合部分和水壳之间形成冷却剂通道。中间管体的外表面连接到波纹管，以形成连接到冷却剂通道的预冷腔。本发明的优点如下：新增预冷水室降低主板和入口室的壁温; 绝缘管中部新增配套提高绝缘管的防振功能; 入口室的特殊结构增加了轴向位移补偿的能力。本发明的上述改进显着提高了EGR冷却器的可靠性。
