    • A hand-held electrically heated tool for applying heat to an object includes an elongated metallic tubular handle open at its forward and rear ends and having a plurality of raised relatively-spaced longitudinally extending vanes formed on its the inner surface and extending between the forward and rear ends thereof. An exposed metal electrical resistance heating element forming a wire tip is mounted in an insulator disposed in the forward end of the handle in engagement with the vanes with the tip extending forwardly of the handle. A spherically concave portion of the insulator reflects heat away from the handle. The vanes extend forwardly of the handle to form prongs spacing the insulator a distance from the forward end of the handle to allow exterior cooling air to enter air spaces defined by the vanes between the insulator and inner surface of the handle, flow the length of the handle, and exit through openings formed in the rear end of the handle by removal of the wall of the handle at discrete areas to expose the vanes and the air spaces therebetween. The outer surface of the handle is fluted to increase heat dissipation and enable comfortable gripping.
    • 用于对物体施加热量的手持电加热工具包括在其前端和后端开口的细长金属管状手柄,并且在其内表面上形成有多个凸起的相对间隔开的纵向延伸的叶片,并且在前部和 后端。 形成线尖的暴露的金属电阻加热元件安装在设置在手柄的前端的绝缘体,其与叶片接合,其末端延伸到手柄的前方。 绝缘体的球形凹部将热量远离手柄反射。 叶片向前延伸到手柄的前面,以形成与绝缘体间隔距离手柄前端一定距离的插脚,允许外部冷却空气进入由绝缘体和手柄内表面之间的叶片限定的空气空间, 通过在离散的区域处移除手柄的壁来使其处于形成在手柄的后端的开口,从而露出叶片和它们之间的空气空间。 手柄的外表面是槽纹的,以增加散热性,并且能够舒适的夹持。
