Beschreibung
Zusammenfassung:	The invention discloses a heating device of exhaust manifold thermal fatigue test equipment. The heating device is used for heating an exhaust manifold on the test equipment. The heating device of the exhaust manifold thermal fatigue test equipment comprises a shell, a cooling water pipeline, a plurality of first heating coils, a plurality of second heating coils, a variable-frequency power supply and a water cooling unit. And the shell is fixedly connected with a lifting mechanism of test equipment. One end of the cooling water pipeline is provided with a water inlet, and the other end is provided with a water outlet. The multiple first heating coils are fixed in the shell and communicate with the cooling water pipeline. And the plurality of second heating coils are fixed in the shell. Therefore, the heating device is simple and reasonable in structure and high in heating efficiency, the variable-frequency power source is used for controlling the heating coil to heat the exhaust manifold, current and voltage
