| 摘要 |
The invention provides a ventilation channel steel, a manufacturing method, a ventilation structure and a motor. The ventilation channel steel provided by the present invention comprises a ventilation channel steel body having a radial-direction wind induction section and a side-direction wind induction section, wherein the side-direction wind induction section is connected with a forward wind end of the radial-direction wind induction section. The wind induction surfaces are provided in the side-direction wind induction section. The wind induction surfaces are distributed in both sides of an extended line of the radial-direction wind induction section and the wind induction surfaces can induce gas flowing through the forward wind end of the radial-direction wind induction section to the both sides of the extended line of the radial-direction wind induction section. According to the ventilation channel steel provided by the present invention, the side-direction wind induction section designed in the forward wind end of the radial-direction wind induction section is capable of inducing cooling gas to the both sides of the ventilation channel steel, and thus, the cooling gas can flow through a cross-section of the forward wind side of both windings of the ventilation channel steel by using the ventilation channel steel so as to intensively cool the forward wind sides of the windings and to reduce the temperature of a local hot spot. |
