New components have been developed for an active thermal control system, to meet the extreme thermal requirements of the SPACELAB fluid science “Critical Point Facility”.A water cold plate with a double spiral fluid channel acts as a variable conductance heat sink for the high precision thermostat. This channel geometry achieves high heat flux densities on its planar isothermal contact surface.A thermostat unit consisting of two thermo-electrical Peltier element heat pumps and one electrical heater regulates the upstream temperature inside an air cooled electronic box. Both of these elements are pulse-width operated, to compensate the environmental temperature fluctuations.
