Definitions
- the present invention relates to a device for conducting a fluid, for example liquid state freon or another liquid, comprising a conduit through which the fluid is conducted in order to be heated or cooled by means of a medium flowing around the conduit.
- a fluid for example liquid state freon or another liquid
- Devices of this kind are used in for example heating systems for preheating the heat carrier liquid.
- the object of the invention is to provide a device of the kind described above, in which the heat transmission between the fluid which is conducted through the conduit and the medium flowing around the conduit is better than in the devices previously known.
- the device according to the present invention is characterized in that a longitudinal, for example thread shaped, element is helically positioned around the conduit with the windings spaced from each other in order to bring the medium flowing around the conduit to perform a circulating motion around the conduit.
- the device comprises at least two conduits each provided with a helical element, the conduits being positioned adjacent each other in parallel relationship while maintaining a distance between the conduits by means of the helically extending elements in order to allow the flowing medium to circulate between the conduits.
- conduits positioned together in parallel with each other are provided in an outer pipe, through which the flowing medium is conducted, and that said outer pipe and the conduits positioned therein extend helically.
- the device according to the invention By means of the device according to the invention there is provided a more effective heat transmission between the outer side of the conduit and the medium flowing around the conduit.
- the conduits can be positioned close to each other inside the outer pipe without causing the outer surfaces of the conduits to contact each other and thereby to obstruct the flowing of the medium outside the conduits.
- a freon liquid is fed in the direction of the arrow 13 through an expansion valve 7 and a distribution head 8 to pipes 5 and conduits 3 connected therewith.
- the windings of the elements 4 are spaced from each other.
- the conduits 3 extend in common into a wider outer pipe 2 preferably consisting of polyetylene and extending as a helix 1.
- the lower end of the helix 1 is connected with a pipe section 15, by means of a hose clamp 14, the pipe section 15 having an outlet 10 for a medium, preferably water, which is supplied to the outer pipe 2 at the upper end thereof.
- the pipes 5 extend through a sealed end portion 6 and into the conduits 3.
- the upper end of the helix 1 is connected with a pipe section 9 by means of a hose clamp 14, the pipe section 9 having an inlet 12 for a hot medium, preferably water, and an outlet 10 for the heated freon liquid, the pipes 3 being fixed by means of a seal end portion 6.
- a hot medium preferably water
