You can't really. It's all hidden behind ACPI magic. You may have a
hint with:

$ grep . /sys/class/thermal/thermal_zone*/device/path

but in general the name is generic and thus not useful. So the only way
to know where exactly ACPI gets its values is by disassembling the
DSDT, and looking for the code behind the thermal zones. Nothing easy
and pleasant.
