The invention provides an exhaust gas cooling structure in an automobile EGR system, and belongs to the technical field of cooling systems. The exhaust gas cooling structure solves the problem of poorstability of an existing EGR system. According to the exhaust gas cooling structure in the automobile EGR system, an automobile comprises a water sleeve, a water-cooled intercooler, an EGR cooler andan engine control unit; the water-cooled intercooler and the EGR cooler are connected through an external cooling pipe, and the water sleeve and the EGR cooler are connected through an internal cooling pipe; and the exhaust gas cooling structure comprises a first electronic valve and a second electronic valve which are both arranged on the external cooling pipe, a third electronic valve is arranged on the internal cooling pipe, and the first electronic valve, the second electronic valve and the third electronic valve are connected with the engine control unit through conducting wires. The exhaust gas cooling structure in the automobile EGR system has the advantage of improving stability of the EGR system.
