It takes energy to change the state of water from liquid to vapor....convection will remove the vapor, but it doesn't provide the energy for the phase change. The purpose of panting is to create convection to decrease the water saturation of the air near the membranes, but the water vapor results in heat loss. Check any book on physiological ecology and they'll talk about it.
