1. A heater assembly for a vaporizer comprising:
a heat exchanger comprising a side wall with an interior surface defining a bore, wherein the interior surface comprises at least one ridge and at least one groove adjacent to the ridge; and
a heater that is positioned in the bore so that the heater deforms the ridge and presses at least a portion of the ridge into the groove.
2. The heater assembly of claim 1 , wherein the heater is press fit into the bore.
3. The heater assembly of claim 1 , wherein an outer surface of the heater is formed from a material that is harder than the interior surface of the heat exchanger.
4. The heater assembly of claim 1 , wherein the interior surface is generally cylindrical, and wherein each of the ridge and the groove is helical.
5. The heater assembly of claim 4 , wherein the ridge and the groove are formed with a tap.
6. The heater assembly of claim 1 , wherein the interior surface is generally cylindrical, wherein a first diameter of the interior surface is measured from a root of the groove on one side of the interior surface to one of the root of the groove on the opposite side of the interior surface or a second root of another groove on the opposite side of the interior surface, and wherein a second diameter of the interior surface is measured from a crest of the ridge on one side of the interior surface to one of the crest of the ridge on the opposite side of the interior surface or a second crest of another ridge on the opposite side of the interior surface.
7. The heater assembly of claim 6 , wherein the heater has a third diameter that is greater than the second diameter.
8. The heater assembly of claim 7 , wherein the difference between the third diameter and the second diameter is between approximately 0.06 to 0.10 mm.
9. The heater assembly of claim 7 , wherein the third diameter is less than the first diameter.
10. The heater assembly of claim 9 , wherein the difference between the first diameter and the third diameter is between approximately 0.03 to 0.05 mm.
11. The heater assembly of claim 7 , wherein the third diameter is between approximately 9.96 to 9.98 mm.
12. The heater assembly of claim 11 , wherein the ridge in the interior surface is helical and formed with an M10 thread tap, wherein the diameter of the bore prior to forming the ridge is between approximately 10 to 10.015 mm.
13. The heater assembly of claim 1 , wherein a helical guide extends outward from an exterior surface of the side wall.
14. The heater assembly of claim 13 , wherein the heat exchanger is positioned within a tube, and wherein a helical groove is defined by the tube, the exterior surface of the side wall, and the helical guide.
15. A method of assembling a heater assembly for a vaporizer, the heater assembly comprising a heater and a heat exchanger comprising an interior surface defining a bore, the interior surface defining at least one groove and at least one ridge adjacent the groove, the method comprising:
pressing the heater into the bore so that the heater deforms the ridge and presses at least a portion of the ridge into the groove.
16. The method of claim 15 , wherein the interior surface is generally cylindrical, and further comprising forming a helical groove in the interior surface with a tap before pressing the heater into the bore.
17. The method of claim 15 , wherein the interior surface is generally cylindrical, wherein a first diameter of the interior surface is measured from a root of a groove on one side of the interior surface to one of the root of the groove on the opposite side of the interior surface or a second root of another groove on the opposite side of the interior surface, and wherein a second diameter of the interior surface is measured from a crest of a ridge on one side of the interior surface to one of the crest of the ridge on the opposite side of the interior surface or a second crest of another ridge on the opposite side of the interior surface, wherein the heater has a third diameter that is greater than the second diameter, and wherein the third diameter is less than the first diameter.
18. The method of claim 15 , wherein the heater is pressed into the bore with a force of between approximately 1 to 3 kN.
