摘要
目前,采煤机电控箱内部有众多的发热器件,如变频器等,由于电控箱内电器件工作时发热量大,对自身及其他器件性能都有影响,为此,采煤机电控箱的内部需要散热。主要是对目前电牵引采煤机电控箱的几种散热方式做了简单的介绍。
At present, there are a large number of heating devices in the mining shearer electrical control box , such as invertor, traction transformers, etc.. While the electrical parts of the electrical control box are working heat, the other devices on the performance of their own have an impact, for which the devices within the electrical control box needs cooling. Several heat ways of the electrical traction coal electric control box to do a simple introduction.
