PTC (Positive Temperature Coefficient) fan heater with uniform heat dissipation

The utility model discloses a PTC (Positive Temperature Coefficient) warm air blower with uniform heat dissipation, which comprises a shell (1), a fan (2) is arranged in the shell (1), and an inner side PTC heating sheet (3) and an outer side PTC heating sheet (4) are sequentially arranged at the front end of the fan (2); and a turbulent flow radiating fin (5) is arranged between the inner PTC heating sheet (3) and the outer PTC heating sheet (4). According to the PTC fan heater, hot air can be led out uniformly while the PTC heating element dissipates heat uniformly, the potential safety hazard that the local temperature of the PTC is too high is solved, the service life of the fan heater is prolonged, and better heating experience is brought to a user. 本实用新型公开一种散热均匀的PTC暖风机，包括壳体（1），所述壳体（1）内设有风扇（2），所述风扇（2）的前端依次设有内侧PTC加热片（3）和外侧PTC加热片（4）；所述内侧PTC加热片（3）和外侧PTC加热片（4）之间设有扰流散热片（5）。本实用新型的PTC暖风机能够使PTC发热元件均匀散热的同时均匀的导出热风，既解决了PTC局部温度过高的安全隐患，提高暖风机的寿命，又给用户带来更佳的取暖体验。
