  Considering the nonlinearity of the Yang Mills charge, we investigate the
Joule-Thomson expansion for the Einstein-Power-Yang-Mills AdS black holes in
the context of the gauge-gravity duality. Under this framework, we calculate
the Joule-Thomson coefficient, describe all relevant inversion and isenthalpic
curves in the temperature-pressure plane that determining in this manner the
corresponding cooling and heating regions. Finally, we analyze the effect of
the charge nonlinearity on the Joule-Thomson expansion.
