The invention discloses a corrugated pipe type gas electric heating device and relates to a gas electric heating device. The device comprises a shell (4), a heater core body, an electric wiring box (1), a heat-preserving bushing (5), an end partition plate (9), an inlet connecting pipe (11) and an outlet connecting pipe (10). The heater core body is a core part of the device and comprises a plurality of corrugated pipes (7), a plurality of flow guiding supporting plates (6), an end plate (3), a flow guiding end plate (8) and an insulating ring sleeve (13). The shell is a sealed metal shell. The heat-preserving bushing is attached to the inner wall of the shell. An annular installing plate (2) is arranged on one side of an air inlet in the inner wall of the shell. The shell and one end of the heater core body are connected and fixed through the end plate on the heater core body. The corrugated pipe type gas electric heating device achieves inside and outside heat exchange of an electric heating component, the device is high in heat efficiency, the wall temperature of the electric heating element is low, heat stress is small, service life is long, and consumption of precious metal electric heating element materials is reduced. The corrugated pipe type gas electric heating device is particularly suitable for the occasions where gas pressure is large and temperature rise is high.
