为什么感应加热线圈要用圆形的铜管制作？

感应加热炉，感应加热设备的感应器制作过程没有规定必须用圆形铜管，只是很多时候圆管容易加工，原料又相对便宜。实际上扁的方管效果更好，磁力线更加密集，均匀。准确的说，用方形的铜管做感应线圈效率更高。感应加热线圈不建议使用圆形铜管。

Why should the induction heating coil be made of a round copper tube?

In the induction heating furnace, the induction heating equipment's inductor manufacturing process does not stipulate that round copper pipes must be used, but in many cases the round pipes are easy to process and the raw materials are relatively cheap. In fact, the flat square tube has a better effect, and the magnetic field lines are more dense and uniform. To be precise, it is more efficient to use a square copper tube as an induction coil. It is not recommended to use round copper tubes for induction heating coils.
