Abstract
A device for converting a liquid into vapor, having an evaporation surface, a liquid inlet, a heater for heating the evaporation surface, a flow controller, a control unit configured to control a liquid flow rate injected into the liquid inlet, a chamber containing the evaporation surface, and a temperature sensor arranged on the evaporation surface. The control unit is configured to control a heating power of the heater according to a flow rate and to a temperature measured by the temperature sensor according to a predetermined control law. The predetermined control law varies, for each flow rate, non-linearly and inversely proportionally to the difference between a reference temperature of the chamber and the measured temperature.
