DESCRIPTION
METHOD AND APPARATUS FOR CONVEYING A HEATING FLUID
CIRCULATING THROUGH AT LEAST ONE HEATING CIRCUIT OF A
HEATING SYSTEM ALONG A CIRCULATiON SECTION The invention relates to a method and apparatus f or conveying a heating fluid circulating through at least one heating circuit of a heating system in a fluid line section along a circulation section according to the preamble of patent claim 1 and the apparatus for carrying out the method according to patent claims 4 to 11.
A heating system generally consists of a cental heat generator which heats a heat transfer medium, in most cases water. Apparatuses an methods are generally known for heating systems in which the heat transfer medium is conveyed through pipes to the radiators by F means of a pumping system or, however, due to the density different of the medium, as result of the temperature differences. The cooled heat transfer medium then flows back again to the heat generator by means of the return Tines in the circuit.
The circuit of the heat transfer medium from the heat generator via the radiators is today predominaiftly maintained by a circulating pump, usually a centrifugal pump. When the pump is operating, the heat transfer medium heated by the heat generator passes via the pipes to the radiators. The medium then delivers heat to the room via the radiators. The circulating speed of the heat transfer medium can be varied, for example, by modulating, possibly by an electrical perfoiance r adaptation of the circulating pump F -2 Such pumping systems have a number of moving parts which are required to convey a heat transfer medium. In the course of time, the weight and the wear of the standard parts can lead to wear of the pumping system which incurs service dosts. In addition, possibly in cases of severe wear of the pumping system, it is necessary to replace standard parts over the lifetime of the equipment.
Furthermore, most pumping systems are prone to particles which accumulate over time in the heat transfer medium. These contaminants in the pipeline system can have the result that a blockage occur-s in the area of the pumping systeni or the motor can burn out, if the medium possibly needs to be conveyed with resistance via the pumping system.
In other areas of technology it is known to influence a medium by means of a specific magnetic effect such that a movement of the medium takes place as a result. F £P 0 446 075 Bl discloses an apparatus in which a number of exciter coils are arranged coaxially in succession and a magnetic field is built up by means of a surrounding magnetic material frame. In this case, the coils are wound with the same polarity and printed circuit boards are mounted between the coils. Axially migrating magnetic fluxes are induced by the eddy currents 1: generated by the printed circuit boards. Further..more, migrating magnetic fluxes are induced in the magnetic circuits closed by Lhe magnetic material frame. The apparatus has a cylindrical.. core which is mounted in the centre of a non-magnetic tube and contributes towards generating the magnetic circuit. An axial thrust is generated by the superposition of the two magnetic fluxes. A molten metal is to be conveyed through the non-magnetic tube. The thrust produced by the magnetic fluxes then acts on the molten metal and conveys it through the tube. However, this complex st..ucture is only suitable to a certain extent for conveying a heating fluid in a fluid line section along a circulation section in a heating system. In addition, the conveyance of molten metal is described in the apparatus described. In order to convey a fluid in a heating system further steps are required to ensure a flow of fluid. The cylindrical core of the apparatus would also hinder the flow of fluid.
It is therefore the object of the invention to optimise the conveyance of a heating fluid circulating through at least one heating circuit of a heating system in a fluid line system along a circulation section so that
disadvantages in the prior art are overcome.
According to the invention, this is achieved by the subject matters having the features of patent claim 1.
Advantageous further developments can be deduced from the dependent claims.
The method according to the invention for conveying a heating fluid circulating through at least one heating circuit ot a heating system along a circulation section is characterised in that a magnetic force of at least two or more individually switchable magnets arranged on the circulation section, acts on the heating fluid in the circulation section and sets the heating fluid in F directional motion. The switchable magnets are mounted around a fluid line section of the circulation section, where the fluid 1 the section consists of a non-magnetisable heat-resistant material.
The magnetic force which is produced acts on the magnetic particles contained in the heating fluid and sets these in directional motion1 with the motion of the particles being transferred to the heating f uid surrounding the particles+ An electromagnetic induction is thereby produced. with this leading to heating. This heating is transferred to the heating fluid and the induced energy is not lost. As a result of the statistic distribution of the particles in the heating fluid, the particles with the surrounding heating fluid flow at different Lime inteials through the switchable magnets. Advantageously in the method according to the invention, the switchable magnets are activated teporally successively in order. The magnetic particles are therefore attracted by the respectively activated magnet. During this the preceding magnets are deactivated in order to prevent a change in direction of the magnetic particles.
An important embodiment of the invention further provides that the annular switchable magnets are arranged in order along a fluid line section of the circulation section. ihis all ows a constant flow without restrictions.
The switchable magnets preferably have an annular configuration and embrace the fluid line section.
conseiently, the magnetic particles surronnded by heating fluid can be moved by the magnetic ring.
In a preferred bodiment, the switchable magnets are located outside, inside or integrated in the fluid line F section. An unimpeded flow of the heating fluid is thus ensured. An addition to the invention is achieved by F: devices assigned to the magnets for restricting the magnetization range. The effects of the magnetic force on the heating fluid and/or the magnetic particles contained in the heating fluid are thus restricted to a predefinable angular range in relation to a longitudinal axis of the fluid line section. F In another advantageous embodiment, the magnetic particles have a coating which prevents the magnetic particles from agglomerating with one another and/or adhering to fluid line walls. Due to clumping of the particles, the agglomerate would block the path for the free magnetic particles. A conveyance of the heating fluid would thus be impeded by the agglomerates. The particles can have a number of compbunds as coating, such as, for example, oleic acid, tetramethyl axmuonium hydroxide, citric acid or soya lecithin.
In another embodiment, the fluid line section is divided into at least two sub-sections arranged parallel to one another and is combined again to a single fluid line section at the end of the circulation section, where switchable magnets are arranged around I: the respectively at least two parallel sections and embrace these. In this embodiment it is possible to convey more fluid through the f mid line sections. It is thereby also ensured that if one sub-section is not F functioning, heating fluid can.be conveyed via the other sub-sections.
In a last embodiment, the fluid line section is arranged in a spiral shape around a cylindrical magnet. F Due to the arrangement of the apparatus the heating fluid can be conveyed in an accelerated manner through F the fluid line section and thus better utilize the induction effect, where the magnet does not embrace the line section. With the method according to the invention and the apparatus as well as the use according to the invention, a possibility for conveying a heating fluid inside a fluid line section is F described. In particular, the apparatus has no moving F parts which could lead to wear due to abrasion.
Furthermore, no blockage due to contaminants in the line system occurs as a result of using this pumping system.
Further features, details and advantages of the invention are obtained from the wording of the claims and from the following description of some exemplary embodiments with reference to the drawings. In the fjgnres; Fig. 1: shows a schematic section in cross-section from a fluid line section with magnetic particles, Fig. 2: shows schematically the structure of a fluid line section with embracing magnetic rings, Fig. 3: shows schematically the structure of a fluid line section with three sub-sections and respectively embracing magnetic rings, Fig. 4: shows schematically the structure of a spiral fluid line section with a cylindrical magnet in side view and plan view and Fig. 5; shows a magnetic particle with coating. F A magnetic force of a plurality of individually switchable magnets 1 arranged on a circulation section Z acts on the beating fluid, not shown, in the circulation section Z and sets the heating fluid in F directional motion. The magnetic force further acts on magnetic particles 2 contained in the heating fluid and sets these in directional motion, where the motion of the particles 2 is transmit ted to the heating f luid.
The magnets 1 are activated and/or deactivated temporally successively in order and the magnetic particles 2 are attracted by the respectively activated magnet 1, whereby a conveyance of the magnetic particles 2 is achieved without a change in direction.
The switchable magnets 1 are arranged in order along a fluid line section 3 of a circulation section Z and have an annular configuration where they embrace the fluid line section 3.
The effect of the magnetic force on the heating fluid and/or the magnetic particles 2 contained in the heating fluid is restricted to a predefinable angular range in relation to a longitudinal axis of the fluid line section 3 by devices 4 assigned to the magnets 1 for restricting the magnetization range.
The magnetic particles 2 further have a coating 5 which prevents the magnetic particles 2 from agglomerating with one another and/or adhering to fluid line walls.
In Fig. 3 a fluid line section 3 is divided into at least two sub-section s 6 arranged parallel to one another and is combined again to a single fluid line section 3 at the end of the circulation section Z. where a plurality of annular switchable magnets 1 are arranged around the respectively,, at least two parallel sections 6 and embrace these.
In Fig. 4 the fluid line section 3 is arranged in a spiral shape around a cylindrical magnet 7.
