利用铝材实现电磁感应的锅具研究

Research on the electromagnetic induction cooker with aluminum material

通常电磁炉不对铝锅进行加热,普遍认为铝材质不能通过电磁感应产生热量.通过实验和理论分析论证,电磁炉不对铝锅进行加热是由于集肤效应确定的感应厚度范围的铝材质的电阻过小造成的.当将铝材的厚度减薄至一定程度,便可通过电磁感应产生可应用级别热量.当负载锅具的等效电阻和电磁炉的等效电阻相当时,可以通过电磁感应产生最大热量.当铝材的厚度为0.035mm时,通过电磁感应产生热量的功率利用率为55.9%.

Usually the electromagnetic cooker can＇t heat aluminum pan, it is generally believed that aluminum material cannot produce heat by electromagnetic induction. Through experimental and theoretical analysis, the induction cooker does not heat the aluminum pan is due to the skin effect to determine the thickness of the induction caused by the resistance is too small. When the thickness of the aluminum material is reduced to a certain extent, the application level heat can be generated by electromagnetic induction. Moreover, when the equivalent resistance of the load cooker is equivalent to the equivalent resistance of the induction cooker, the maximum heat can he generated by electromagnetic induction. In this paper, when the thickness of aluminum material is 0. 035mm, and the power utilization rate of heat generated by electromagnetic induction is 55 %.
