出する。Function When the heat exchanger is operating, the working fluid inside the heat pipe becomes vapor in the evaporator and reaches the upper header of the condenser.The vapor is further cooled by the cold gas outside the pipe, so it condenses. It becomes a liquid and falls by gravity into the lower header of the condenser. If there is a non-condensable gas here,
Due to buoyancy, the non-condensable gas moves up the separation tube and collects in the gas reservoir. At this time, the liquid is removed by a mist eliminator. Therefore, if there is a difference between the temperature measured by the first thermometer and the temperature measured by the second thermometer, and the temperature difference exceeds the specified value, the control device will
Open the control valve and at the same time start the forced gas discharge device to discharge the non-condensable gas in the gas reservoir out of the system in a short time.
