Physical location of thermal zones

Recently I’ve bought a Jetson nano development kit. Looking in /sys/devices/virtual/thermal one can find a handful of ‘thermal zones’ being mentioned. Just out of curiosity, where are those zones located on the Jeston nano? I’ve found technical reference manuals for other members of the Jetson family, but not for the Jetson nano.

Most of zones are in tegra chip for CPU, GPU and DDR port etc. BTW, what manuals of other Jetson products do you get?
