What is the maximum efficiency of high frequency quenching equipment?

First of all, we need to know that this efficiency actually refers to two aspects: thermal efficiency and electrical efficiency!

1. Thermal efficiency

“Thermal efficiency” is based on time. For example, if a heating object is used at the same power consumption, there is a difference between heating for one hour and heating for two hours. The advantage of induction heating is that it can quickly put power on the load, and then the concept of time for money. The key to energy saving of high frequency quenching equipment is here.

2. Electric efficiency

If it is “electrical efficiency”, it is theoretically difficult to exceed 85%; because the main board, IGBT, rectifier and other components of the high-frequency quenching equipment will heat up, which is a part of the loss that cannot be ignored;

Furthermore, if it is “electrical efficiency”, the electrical efficiency of high-frequency quenching equipment has nothing to do with the operating time of the equipment, and the electrical efficiency is measured in KW/H. Therefore, compared with the heating wire, the electrical efficiency of the high frequency quenching equipment is not as good as the heating wire.
