CLOSED LOOP ICING CONTROL FOR HEAT EXCHANGERS
A heat exchanger has a heat exchanger body (39), an inlet (24) for a fluid to be cooled, and an outlet (26) for the fluid to be cooled. There is also an inlet (30) for a cooling fluid and an outlet (32) for the cooling fluid. The cooling fluid and the fluid to be cooled connects to the heat exchange...

Zusammenfassung: | A heat exchanger has a heat exchanger body (39), an inlet (24) for a fluid to be cooled, and an outlet (26) for the fluid to be cooled. There is also an inlet (30) for a cooling fluid and an outlet (32) for the cooling fluid. The cooling fluid and the fluid to be cooled connects to the heat exchanger, but are maintained separate in the heat exchanger such that the cooling fluid lowers the temperature of the fluid to be cooled. The cooling fluid and the fluid to be cooled connects to pass through the heat exchanger, but are maintained separate such that the cooling fluid lowers the temperature of the fluid to be cooled. An ice detector (34) detects an undesirable amount of ice particles in the cooling fluid. A control receives information from the ice detector and controls electric heating elements should an undesirable amount of ice particles be detected. An aircraft is also described. |
