1. Apparatus for providing a heated fluid to a vehicle surface comprising:
- a) an inlet port for receiving an amount of fluid;
b) an outlet port for dispensing an amount of heated fluid;
c) an electrically conductive tube including two tubes of dissimilar material coupled together through which fluid passes from the inlet port to the outlet port for heating fluid passing through said two tubes as it passes from the inlet port and the outlet port; and
d) a control circuit for energizing at least a portion of the electrically conductive tube with a voltage to create an electric potential drop across said portion of the electrically conductive tube to cause current to flow in walls of said tube to heat the electrically conductive tube and the fluid passing through said electrically conductive tube from the inlet to the outlet.

Abstract
A deicing system for use with a vehicle. Apparatus of the system has an inlet port for receiving a fluid; an outlet port for dispensing a heated fluid; an electrically conductive tube connecting the inlet port and the outlet port for heating fluid passing through the tube from the inlet to the outlet; and a control circuit for energizing opposite ends of the coiled tube with a voltage to heat the tube and the fluid passing through the tube.

19. A method for providing a heated fluid to a vehicle surface comprising:
-
a) coiling a conductive tube constructed of two different conductive metals wherein a first section of said tube is coiled to form a first coiled section and a second section is coiled less tightly to form a second coiled section and wherein the first coiled section fits within a center portion of the second coiled section;
b) coupling one end of the conductive tube to a source of washing fluid;
c) routing a washing fluid into an inlet port of the conductive tube such that the fluid flows from the inlet to an outlet of said conductive tube;
d) energizing at least a portion of the conductive tube with a voltage that creates a voltage drop along said portion and heats the conductive tube and the fluid passing through the conductive tube; and
e) emitting the fluid from the conductive tube from an outlet port in fluid communication with a nozzle for dispensing heated fluid against said vehicle surface. - View Dependent Claims (20, 21, 22, 23, 24, 25)
