2 BACKGROUND OF THE INVENTION
In many industries it is often necessary to heat liquids that exist in cold environments. Usually, these liquids are stored in tanks or other large reservoirs or they exist naturally in the environment. It is desirable to keep these liquids from freezing or to thaw these liquids if they do freeze. This is typically achieved by using heating mechanisms that are bulky, inefficient, and difficult to use.

8 coil 18. In another embodiment, supply line 32 may be coupled to a non-corrosive, thermally conductive extender that is coupled to outer helical coil 18 so that supply line 32 does not come in contact with contents of reservoir 14. The heated fluid may flow from heater 12 through supply line 32 into outer helical coil 18. Once the heated fluid is inside outer helical coil 18, heat energy may transfer from the heated fluid to outer helical coil 18. Because outer helical coil 18 may be in thermal contact with the contents of reservoir 14, heat energy may transfer from outer helical coil 18 to the contents of reservoir 14. As the contents closest to outer helical coil 18 are heated, they may become less dense and rise. The cooler contents of reservoir 14 may then flow towards outer helical coil 18 thereby heating the contents of entire reservoir 14 instead of just the contents adjacent to outer helical coil 18. The heated fluid inside outer helical coil 18 flows from outer helical coil 18 to inner helical coil 20. The heated fluid may continue to heat inner helical coil 20 in a similar manner.
Inner helical coil 20 may also continue to heat the contents of reservoir 14. The heated fluid may become less hot as heat energy transfers from the heated fluid to helical coils 18 and 20. In one embodiment, inner helical coil 20 may be coupled to one end of return line 34. In another embodiment, return line 34 may be coupled to a non-corrosive, thermally conductive extender that is coupled to inner helical coil 20 so that return line 34 does not come in contact with contents of reservoir 14. The other end of return line 34 may be coupled to heater 12. The heated fluid may flow from inner helical coil 20 back to heater 12 through return line 34. Heater 12 may reheat the heated fluid and pump the heated fluid into supply line 32 to continuously heat the contents of reservoir 14.
FIGURE 2 illustrates one embodiment of helical coil heating apparatus 10 coupled to supply line 32 and return line 34. In this embodiment, exposed tube 16 is formed into an outer helical coil 18 and an inner helical coil 20. In other embodiments, tube 16 may have any number of coils. Outer helical coil 18 and inner helical coil 20 may be formed of a plurality of rings that are arranged to extend in a longitudinal direction. As shown, outer helical coil 18 is substantially cylindrical. It will be appreciated, however, that outer helical coil 18 may be of any shape.

In another embodiment, return line 34 may be coupled to a non-corrosive, thermally conductive extender that is coupled to inner helical coil 20 so that return line 34 does not come in contact with contents of reservoir 14. The other end of return line 34 may be coupled to heater 12. The heated fluid may flow from inner helical coil 20 back to heater 12 through return line 34.

9 relation to Figure 5, in one embodiment, outer helical coils 18 and 20 may have one or more planar surfaces and may be shaped substantially as a -D.- In the present embodiment, outer helical coil 18 is formed around inner helical coil 20 and there is a gap between outer helical coil 18 and inner helical coil 20. Outer helical coil 18 may be separated from inner helical coil 20 by any suitable means. In this embodiment, tube 16 has a first end 40 and a second end 42. First end 40 of tube 16 terminates outer helical coil 18. Second end 42 of tube 16 terminates inner helical coil 20. First end 40 and second end 42 may be next to each other and may face substantially the same direction. For example, in one embodiment, ends 40 and 42 may terminate in a position that is parallel to the longitudinal direction of the plurality of rings. Tube 16 may be made of any material including any thermally conductive material. In some embodiments, tube 16 may be made of a non-corrosive material such as stainless steel. Tube 16 may be of any shape. Tube 16 may be made of a flexible or malleable material. It may be possible to change the shape of tube 16 depending upon the intended use of heating apparatus 10. In the present embodiment, spacer frames 24a and 24b are used in conjunction with outer helical coil 18, and spacer frames 24c and 24d are used in conjunction with inner helical coil 20 as discussed in greater detail with respect to Figure 4 below. Here spacer frames 24a and 24b are positioned on different portions of outer helical coil 18. Similarly, spacer frames 24c and 24d are positioned on different portions of inner helical coil 20. Although spacer frames 24a and 24b and spacer frames 24c and 24d are all illustrated herein, it should be understood that any number and combination of spacer frames 24 can be used depending on the particular needs of the heating apparatus 10.
