The invention is a heating anti-scalding radiator, including water channel and radiating fin, where there is heat-isolating bar arranged outside of radiating fin. As being a radiator with convective heat radiation as the main mode, it also includes outer fin, where the radiating fin is connected with the outer fin through thermal insulating piece and a convective heat radiating cavity is formed between the radiating fin and the outer fin; as being a radiator with radiant heat radiation or radiant and convective heat radiation as the main mode, outside fin of the radiating fin is provided with many raised fillets, the outer edge of each fillet are installed with thermal-insulating bars and the space between thermal-insulating bars is less than the width of human finger. Because it arranges the thermal insulating bars with better thermal insulating performance at the outer end of the higher temperature radiating fin, thus reducing the temperature of the part where the radiator can contact with the human body, able to effectively prevent scalding the human body and simultaneously maintaining higher radiating efficiency.
