Patent ID: 8444093

Claim:
An airplane de-icing apparatus for de-icing a leading edge of an airplane with a heat transfer fluid, the airplane deicing apparatus comprising: a counter current heat exchanger; a reservoir tank; a first pump; a first reservoir tube joined to the first pump and the reservoir tank, and a first pump tube and a check valve and wherein the first pump tube is joined to the check valve and the first pump; an inlet tube joined to the check valve and the counter current heat exchanger, and wherein a first reservoir inflow tube is joined to the countercurrent heat exchanger and the reservoir tank; a second pump; a second reservoir outlet tube joined to the second pump and the reservoir tank, and a delivery tube joined to the second pump; a tap tube joined to the delivery tub; a solenoid valve joined to the tap tube; a diffuser tube joined to the solenoid valve; a heat diffuser joined to the diffuser tube; a diffuser return tube joined to the heat diffuser; a common return tube joined to the diffuser tube and the reservoir tank; and, wherein the first pump is capable of pumping the heat transfer fluid from the reservoir tank and through the check valve, through the counter current heat exchanger such that the heat transfer fluid is heated and back to the reservoir tank, and wherein the second pump is capable of pumping heat transfer fluid from the reservoir tank, through the delivery tube, the tap tube, the solenoid valve, the diffuser tube, and the heat diffuser and returning the heat transfer fluid back to the reservoir tank through the diffuser return tube and common return tube such that the heat transfer fluid in the heat diffuser is capable of de-icing the leading edge of the airplane.
