High Frequency Induction Heating Equipment Green Environmental
Protection Equipment With Good Safety Performance
Overview of high frequency induction heating equipment:
High frequency induction heating equipment is popular because of
its fast heating speed, small size, large capacity, multi-purpose
of one machine, energy saving and local heating, which can reduce
heat loss. However, high frequency induction heating equipment
needs water, because the machine is cooled when working under high
power. Such as power components main rectifier, IGBT or MOSFET,
high frequency transformer and induction coil. Due to the thermal
effect of current, these elements and components will inevitably
generate a certain amount of heat when they work under high current
conditions, resulting in incidental temperature rise.

Common cooling methods of high frequency induction heating
equipment:
Common cooling methods include natural cooling and forced cooling,
and forced cooling includes air cooling, oil cooling (oil
immersion), water cooling and artificial cooling.
In high-frequency induction heating equipment, in order to ensure
the cooling effect, more than two cooling methods are generally
used. In the early stage, air cooling and oil cooling are generally
used. Because the oil immersion cooling method is not only complex,
heavy, volatile, and can only be cooled locally. Therefore, air
cooling and water cooling are mostly used now, and some artificial
cooling can be added when there is a special need.
