Background

At present, in order to improve the heat dissipation efficiency, the air-cooled PTC electric heater with higher heat conversion efficiency basically adds heat dissipation fins on the outer side of the PTC heating element, and the heat is conducted to the heat dissipation fins or the heat generation belt by the PTC heating element and then is transferred to cold air from the surface of the heat dissipation fins to achieve the heating effect. For example, chinese patents CN109246874A, CN109068411A, CN203537577U and CN207883878U disclose structural forms of the PTC heating element and the heat radiating fins. However, this structure has some disadvantages, such as a certain loss of thermal efficiency in the heat conduction process from the heating element to the heat dissipation fins, and uneven surface temperature distribution caused by high central temperature of the heating element and low temperature of the heat dissipation fins far from the heating element, which causes uneven heating of the cooling air and further affects the thermal efficiency.

Some spring type electric heating wire heaters are exposed outside air, but the heat contact area is small, the spring type electric heating wire heaters are easy to be oxidized and lose efficacy, and some spring type electric heating wire heaters are separated by a glass tube to prevent oxidation, but the heating efficiency is not high as other types of electric heaters, so that the spring type electric heating wire heaters are not suitable for technical development requirements.
