The invention relates to the technical field of automobiles, and provides a columnar air-heating PTC heater with air supplied at two ends and an automobile, the columnar air-heating PTC heater comprises a cylindrical heat pipe, the front end and the rear end of the heat pipe are transparent, a rotating shaft is rotatably mounted in the heat pipe, fan blades are coaxially mounted at the front end and the rear end of the rotating shaft, and the fan blades are located at an opening of the heat pipe; when hot air is conveyed, the fan blades on the rear side rotate to generate wind power, the wind power passes through the PTC heating ring and is heated, the heated wind power flows through the opening of the cylindrical flow guide pipe and the multiple flow guide holes formed in the flow guide pipe and converges at the rotating fan blades on the front side, and under the action of the fan blades, the hot air is evenly mixed, and the heating efficiency is improved. Due to the fact that wind force is small in resistance and short in stroke, certain air outlet volume and air speed at the air outlet of the heat pipe are guaranteed; according to the design, the air outlet temperature is kept uniform, the air outlet efficiency is guaranteed, the user experience is improved, and the heating efficiency of the lift car or the battery is guaranteed.
本申请涉及汽车技术领域,提供一种两端送风的柱状风暖PTC加热器和汽车,包括呈筒状的热管,热管的前后两端均呈通透状,热管的内部转动安装有转轴,转轴的前后端均同轴安装有扇叶,且扇叶位于热管的开口处;在输送热风时,后侧的扇叶转动产生风力,风力经过PTC加热环并被加热,加热后的风力经筒状的导流管的开口和导流管上开设有的多个导流孔流动,并在前侧的转动的扇叶处汇聚,在扇叶的作用下,不仅使得热风均匀混合,而且由于风力受到的阻力小且行程短,保证了热管出风口处一定的出风量和风速;该设计既使得出风温度保持均匀,而且保证了出风的效率,提高了用户的体验,保证了对轿厢或电池的加热效率。
