I'm going to mount 4 SSR's in a 16x16x4" or 6" metal enclosure and I was wondering if the SSR's still needed a heatsink? I know it's best practice, but what's reality? If I mount the SSR's directly, they will be mounted to a mounting plate in the enclosure. Each SSR will control the hot legs of a 220V 4500W or 5500W heating element for my boil kettle or HLT.
Alternatively if the SSR's still need a heatsink, can I mount to the mounting plate and use a fan to circulate cool air?
