Description

An IGBT induction heating device

technical field

The utility model relates to the technical field of heating equipment, in particular to an IGBT induction heating equipment.

Background technique

IGBT high-frequency induction heating adopts the induction heating process. Induction heating is to directly heat the workpiece and put the workpiece into the inductor (coil). When an alternating current of a certain frequency is passed into the inductor, an alternating magnetic field is generated around it. The electromagnetic induction of the alternating magnetic field causes a closed induced current—eddy current in the workpiece. The distribution of the induced current on the cross-section of the workpiece is very uneven, and the current density on the surface of the workpiece is very high and gradually decreases inward. The skin effect, the electrical energy of the high-density current on the surface of the workpiece is converted into thermal energy, which increases the temperature of the surface layer, that is, surface heating is achieved.

The traditional IGBT induction heating equipment dissipates heat to the IGBT module through the heat dissipation fins, and the heat dissipation efficiency of the fins is relatively low. When the number of IGBT modules is large, the heat dissipation deception cannot quickly dissipate the heat into the air, which affects the normal operation of the IGBT module. At the same time, the dustproof effect of traditional IGBT induction heating equipment is not good enough, and the dust will enter the inside of the equipment through the barrier net, which is easy to cause damage to the electronic components inside the equipment. For this reason, we provide an IGBT induction heating equipment.
