AI Technical Summary
Existing RC protection modules suffer from excessive heat generation due to the inability to dissipate the heat generated by the resistors, leading to excessive temperature rise of adjacent components and affecting their lifespan.
Resistors are used instead of resistors, and combined with the design of heat dissipation aluminum plate and insulating glue, the heat is transferred by expanding the plane to make large-area contact with the heat dissipation aluminum plate. At the same time, the use of heat insulation board avoids parasitic coupling and enhances the fixing strength.
It effectively prevents resistor overheating, improves module heat dissipation efficiency and reliability, extends service life, and avoids parasitic coupling between capacitors and resistors.
