Definitions
- the invention relates to a heating device with a heat dissipation body for pre-warning of heating oil, as specified in the preamble of claim 1.
- today's oil burners are designed in such a way that they can be used for a relatively large output range and that they can only be adapted to the special needs of the individual customer It is necessary to insert a suitable nozzle and adjust the air supply. If, however, resistance-heated electrical preheating is also provided in the oil burner, this would have to be adapted to the respective oil throughput. This would make assembly work considerably more difficult. Care should be taken to ensure that, on the one hand, the oil is heated to a sufficiently high temperature, for example above 70 ° C., and that the final state is reached relatively quickly. On the other hand, however, in the event of a brief standstill or when the oil supply is interrupted, no oil overheating with steam formation may occur, the steam formation in particular being able to impair further oil production.
- Electric heating by means of a heating winding would therefore also make very complex control electronics necessary.
- the aim is not only to design such oil burners as simply as possible, but also to make them reliable.
- a PTC thermistor is a component made of a material based on the barium titanate, which has a self-controlling temperature-resistance characteristic due to known manufacturing measures and doping.
- PTC thermistor material as can be seen, for example, from “Ceramic time- *, the so-called Curie temperature, a specific material size, leads to an extreme increase in the specific electrical resistance with a further rise in temperature.
- FIG. 1 shows a diagram from which the temperature-resistance characteristic with an indication of the Curie temperature and the slope emerge.
- heating of the supplied heating oil does not need to be as strong for larger supply quantities (within the specified range), as is the case e.g. for the lower limit of 0.3 1 per hour.
- FIG. 2 An exemplary embodiment of a heating device according to the invention is shown in FIG. 2 described below.
- the heating device which has a heat dissipation body 32 with an intermediate space 33 provided for receiving the PTC heating element 4.
- This heating element has the physical sizes specified.
- Electrodes 8 are shown in section on the surfaces of the plate-shaped heating element 4 perpendicular to the plane of illustration of the figure.
- the heating element 4 is wedged into the intermediate space 33 by means of the wedge-shaped bodies 37 and 137, which have a wedge angle ⁇ , in such a way that, apart from one firm mounting also good thermal contact from both surfaces of the heating element 4 on the heat-dissipating surfaces 35 and 36 of the heat dissipation body 32 takes place.
- 10 ductile inserts are designated.
- connection Lines of the electrodes 8 designated, to which a voltage of 110 volts or 220 volts (or an intermediate voltage value) can be applied.
- the upper portion 132 of the heat dissipation body 32 in the illustration in the figure is designed such that a tube with good thermal contact can be inserted into the semicircular cylindrical recess 133, as is usually used as a copper tube for oil production from the tank system to the burner.
- 134 denotes a counterpart which is expediently to be used and matches the portion 132. This has the portion of a recess which supplements the recess 133 to form a cylinder. With the help of the screws 135, this part 134 can be fastened on the heat dissipation body 32, as can be seen, in such a way that the copper pipe 5 of the oil production line is firmly clamped with good thermal contact.
- the section 134 can also be replaced by a perhaps less complex mounting of the heat dissipation body 32 on the tube 5.
- a heat dissipation body for a heating device has a measured length (perpendicular to the plane of the figure) of e.g. 4.5 cm for a tube 5 with e.g. 8 mm outer diameter.
- the PTC thermistor plate 4 has a thickness of approximately 2 mm and 10 cm 2 total area of both plate surfaces.
- a PTC thermistor material for a given operating voltage of 220 volts one is used that has a Curie temperature T c of 160 ° C and at this reference temperature T c has a specific electrical resistance of approx. 17000 Ohm ⁇ cm.
- the Curie temperature is selected so that it is about 10 to 120 ° C higher than the temperature that the oil to be heated should reach at maximum. With a flow rate of only 0.3 1 per hour, the oil flowing through at the specified 220 volt operating voltage reaches approximately 110 ° C.
- the temperature of the PTC thermistor plate 4 adjusts itself to a temperature of 170 ° C at which the plate delivers 35 watts of heating power. This is achieved when the slope the increase in resistance is at least 20% / ° C. If an amount of oil flows from 2 l per hour under the same conditions, the oil heats up to a still 73 ° C, whereby the PTC thermistor plate 4 then emits 70 watts because the PTC thermistor plate 4 only dissipates when the amount of heat dissipated still heated to about 167 ° C.
- ⁇ o 4300 Ohm ⁇ cm at a Curie temperature of 160 ° C.
- a quantity of 2 liters of oil flowing through per hour is then heated to 73 ° C. with a heating output of 70 watts.
- the lower limit of the respective range of variation for ⁇ o values in question is about a factor of 10 lower than the values given above. In each case smaller values of ⁇ o lead to a somewhat higher temperature of the oil flowing through and to be heated.
