On page 29 of the below app note, there is a “heat spreader”. This is simply a “wrapping” of aluminium foil to go round the inner wall of a totally enclosed SMPS.
It does not actually connect physically to any of the heatsinking or components on the SMPS PCB.
The wall of the SMPS enclosure is totally enclosing and made of plastic.
Do you think such a “heatspreader” will really have a significant effect in cooling the components of the SMPS PCB? Surely not?
