if the top of the enclosure is heated and it radiates all through the enclosure from there, how would that not increase the ambient temperatures?

when you heat a side of the enclosure and it radiates all through the enclosure from there, how would that not increase the ambient temperatures?

some heat stays local, some heat gets dispersed via infrared radiation, some of the heat gets dispersed by air movement. all a RHP does is that it tries to minimize localized heat.
