In the electric circuit of the induction cooker, there are some electric elements which generate a lot of heat during operation. Such as a power tube. Power tubes (e.g., IGBTs) are key components for controlling the switching of induction cooker heating elements (e.g., coils). The power tube of the induction cooker is usually subjected to high-frequency switching operation, so that the heating of the power tube is remarkable. Taking an IGBT as an example, since the IGBT has a low on-voltage drop in the on state, there is a certain power loss to be converted into heat, which means that in high power applications, the IGBT generates high heat. In order to sufficiently dissipate heat, these heat-generating components are usually provided in a housing of an induction cooker, and a heat radiation fan and a heat radiation plate are generally provided in the induction cooker, and the heat radiation plate is attached to a power tube mounted on the housing or a circuit board of the induction cooker, and is blown to the heat radiation plate by the heat radiation fan to radiate heat. In this way, however, the heat from the power tube is still transferred directly to the circuit board or to the underside of the housing of the induction cooker. When the power tube is directly arranged on the inner bottom surface of the induction cooker shell, if the heat dissipation effect is not good enough, heat is easy to accumulate on the bottom surface of the induction cooker shell, so that the induction cooker shell is heated to deform or the color is changed. When the power tube is directly arranged on the circuit board of the induction cooker, if the heat dissipation effect is poor, the normal use of the circuit board can be possibly affected.
