Description

Technical Field

[0001] The utility model relates to the technical field of induction cookers, in particular to a single-fan heat dissipation air duct structure of an induction cooker. Background Art

[0002] Induction cookers mainly use the alternating magnetic field generated by the electromagnetic wire coil for heating. In order to generate the alternating magnetic field, a high-frequency alternating current needs to be passed into the electromagnetic wire coil, which requires the use of switching elements such as IGBT to control the current passed into the electromagnetic wire coil. This will cause the IGBT, electromagnetic wire coil and other components to generate high heat, so it is necessary to design a corresponding heat dissipation structure on the induction cooker. At present, the induction cookers on the market mainly use heat sinks superimposed on the IGBT and use heat dissipation fans to convectively dissipate heat from the heat sink and electromagnetic wire coil. However, the existing heat dissipation method has poor restraint effect on the air duct, and the airflow will spread to the surroundings. Without increasing the air supply volume, the heat dissipation effect is poor, which will lead to incomplete heat dissipation and rapid performance degradation of the heating element, thereby affecting the life of the entire machine.
