Problems solved by technology

In the traditional heat sink design process, it relies more on the experience of the designer, if it is successful, it will continue to be used, and if it cannot meet the actual needs, it will be replaced
This design method has two major disadvantages. First, the traditional method cannot optimize the selected radiator, and cannot guarantee that the selected radiator parameters are the optimal situation under the current conditions; secondly, the traditional selection method has hysteresis. Design changes often occur after power device failures, resulting in waste of design costs and cycles
