Electrical heater for heating substantially cylindrical objects
摘要：
The present invention relates to an electric heater (22) to heat substantially cylindrical objects (12), in particular hot runner nozzles (10) of hot runner systems, essentially being fitted with at least one cylindrical support and with at least one heating conductor track (28) deposited on the support (12). To reduce premature failure of the heater, the invention stipulates that each heating conductor track (28) runs substantially in the axial direction (A) of said support (12), the heating conductor tracks (28) being connected to each other by conductor tracks (30) of lower electrical resistance and each conductor track (30) running essentially in the tangential direction (T) of the support (12).
摘要（中）：

本发明涉及一种用于加热基本上圆柱形物体（12），特别是热流道系统的热流道喷嘴（10）的电加热器（22），其基本上装配有至少一个圆柱形支撑件和至少一个加热导体轨道 （28），其沉积在所述支撑件（12）上。 为了减少加热器的过早失效，本发明规定每个加热导体轨道28基本上在所述支撑件（12）的轴向（A）上延伸，加热导体轨道（28）通过导体轨道 （30），并且每个导体轨道（30）基本上在支撑件（12）的切线方向（T）上延伸。
