SYSTEM FOR CONTROLLING TEMPERATURE OF A BODY
WO2022179907 A1
A system for controlling temperature of a body (6) comprising a DBD actuator (9) connectable to a power source to produce an ionic wind on the body; a control unit (8) to select an initial configuration and to control the power source (5) depending on a temperature difference (ΔT) between an input temperature (Ti) and a target temperature (Tta) on the body (6), wherein the initial configuration comprises the following constructive parameters of the DBD actuator: number, shape, geometry, relative position of electrodes (d), dielectric material, dielectric thickness (e), wherein the initial configuration further comprises the following setting parameters to be set in the power source (5): a frequency value (f), an amplitude value (V), a waveform signal and a duty cycle, wherein the control unit (8) adjusts the initial configuration by modifying any of the setting parameters to control the heat transferred to the surface of the body.
- Controlled cooling by forced convection in areas where volume is a constraint (electronic components, elimination of hot spots in mechanical systems). - Heat generation in ice-prone areas where aerodynamics are a limitation (aircraft wings, wind turbine blades, ice prevention and elimination). - Simplicity and flexibility in control, robustness and reliability. - Short response time (~ ms) - Minimum weight and volume. - Low energy consumption.
