迄今点火线圈热计算方法尚未研究出来,在某种情况下,点火线圈在其工作过程中其过热往往有可能超过允许的规定。 热计算的困难首先是因点火线圈的工作过程复什,绕组(初级和次级)和外磁路片中量耗难以计算;此外,点火线圈是不同类体,发出的热被分布在绕组及铁心的体积中,这就更增加了计算的困难。 本文所提出的是汽车用点火线圈的计算和热计算。 Hitherto the ignition coil heat calculation method has not yet been developed, in some cases, the ignition coil overheating its operation may often exceed the allowable provisions. The heat calculation difficulty is mainly due to the work process of the ignition coil, the amount of winding (primary and secondary) and the outer magnetic circuit is difficult to calculate; In addition, the ignition coil is a different body, the heat is distributed in the winding and In the core of the volume, which adds to the calculation more difficult. What this text puts forward is the calculation and the heat calculation of the ignition coil used in the car.
