| Abstract: | To address the poor temperature uniformity of conventional heating systems in photovoltaic module laminators, this paper proposes an electromagnetic induction heating method incorporating temperature control. An electromagnetic–thermal coupling model was developed using COMSOL Multiphysics 6.3 to quantitatively analyze the effects of current, frequency, and coil-to-plate gap on the temperature rise of the heating plate. Through optimized coil turn distribution, addition of insulation cotton, and implementation of on-off control, precise regulation of the heating plate temperature was achieved. Experimental validation was performed using a small-scale electromagnetic induction heating platform. The results demonstrate that the influence of parameters on temperature uniformity follows the order current intensity > frequency > gap. The optimized system stabilized the effective working surface within 150 ± 2 °C in approximately 5500 s, maintaining this temperature range during subsequent operation, thereby meeting the process requirements for lamination. This study provides valuable insights for optimizing heating systems in photovoltaic module manufacturing. [ABSTRACT FROM AUTHOR] |
