The invention relates to an oil heating device, which comprises a heating tube made form non-metallic material. Wherein, the heating tube via the support elements comprises the heating elements made form metals to heat the oil; the outer surface of said heating tube is coiled with the sensing coil connecting the alternating current power. The invention uses the electromagnetic sensing theory to heat transmitted oil inside the oil tube, with high electric heating efficiency and reduce the heat loss, without using thermal-insulating material to avoid the heat loss between the heated oil and the heat source. It has less maintenance and lower cost. The oil in the heating tube can be heated when flowing along the inner and outer surfaces of heating elements, while the temperature field inside the oil is uniform distributed to make the temperature control easily. The invention makes the heating elements emit heat according to the electromagnetic sensing theory and uses the heating elements to heat oil without environment pollution.
