The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A mold comprising:
a fluid channel;
a fluid inlet;
a fluid outlet;
the mold comprising a PTC-ceramic;
wherein, upon application of a voltage, the mold is heated such that a fluid passing through the fluid channel can be heated.
2. The mold according to claim 1, wherein the fluid inlet is larger than the fluid outlet.
3. The mold according to claim 1, wherein the fluid channel comprises a first subsection and a second subsection; and
wherein a cross section of the first subsection is larger than a cross section of the second subsection.
4. The mold according to claim 3, wherein an inner surface of the mold in a first subsection of the fluid channel is enlarged via geometric protrusions.
5. The mold according to claim 4, wherein each protrusion comprises a laminar form.
6. The mold according to claim 5, wherein the protrusions comprise ribs.
7. The mold according to claim 6, wherein the ribs are helical.
8. The mold according to claim 1, wherein an inner surface of the mold is formed in a manner such that fluid flowing through the fluid channel rotates around an axis along which the fluid flows.
9. The mold according to claim 1, wherein the mold comprises a plurality of fluid outlets.
10. The mold according to claim 1, wherein the fluid is a liquid.
11. The mold according to claim 10, wherein a composition of the PTC-ceramic is based on a boiling point of the liquid.
12. The mold according to claim 10, wherein the liquid comprises ethanol as a main component.
13. The mold according to claim 1, wherein the PTC-ceramic comprises BaTiO3 as a main component.
14. The mold according to claim 13, wherein the BaTiO3 is doped in a manner such that a resistance of the PTC-ceramic reaches a level at which electric current through the PTC-ceramic is reduced to prevent further heating of the PTC-ceramic.
15. The mold according to claim 1,
wherein a composition of the PTC-ceramic is:
ABO3+SiO2,
wherein A is one or more of Ba, Ca, Sr, Y, and Pb; and
wherein B is one or more of Ti and Mn; and
wherein a part of Si is 0.5 to 4.5 mol percent of a sum of both components.
16. The mold according to claim 15, wherein A comprises the following parts in mol percent: Ba 80%-85%, Ca 10%-15%, Sr 1%-5%, Y 0.1%-1%, and
wherein B comprises the following parts in mol percent: Ti 99.8-99.99%, Mn 0.01%-0.2%.
17. The mold according to claim 1, wherein a concentration of any metallic impurity is lower than 10 ppm of the PTC-ceramic.
18. The mold according to claim 1, wherein the mold is injection molded.
19. The mold according to claim 1, wherein the mold comprises an electrically conductive layer on an inner surface of the mold and on an outer surface of the mold.
20. The mold according to claim 1, wherein an inner surface of the mold comprises a passivation layer.
21. The mold according to claim 10, wherein the fluid is a fuel.
22. The mold according to claim 21, wherein the fuel comprises ethanol as a main component.
23. An arrangement comprising
a mold according to claim 1; and
a nozzle;
whereby fluid first passes through the mold and is then ejected by the nozzle.
24. The arrangement according to claim 23, further comprising a valve is arranged between the nozzle and the mold.
