Definitions

  • the present invention relates to a fluid heating device with a tube through which a fluid flows.
  • a fluid heating device of the type mentioned in which the heating element is attached as an electrical resistance band on the outer circumference of the fluid tube.
  • the indirect heating of the fluid via the pipe wall means that the heating device cannot be switched on and off quickly without delaying the heating and switching off of the heating of the fluid.
  • the object of the present invention is to provide a fluid heating device which is inexpensive to manufacture and which allows the heating device to be switched on and off quickly.
  • the object of the invention is achieved in a fluid heating device in that the tube is concentric a radiator surrounded by a quartz jacket is arranged.
  • a particular advantage of the present invention is that the quartz jacket stores only a small amount of residual heat, as a result of which the fluid is no longer heated immediately after the fluid heating device is switched off.
  • the quartz jacket is a quartz tube which contains the radiator in the form of an electrical heating element. At least a portion of the quartz tube preferably contains a heating wire. If several sections of the quartz tube contain a heating element, a greater heating output is achieved by interconnecting the several heating elements.
  • a safety temperature sensor is provided on the outer circumferential section of the fluid pipe opposite the section of the quartz pipe.
  • a heating current flowing through the heating wire is preferably switched off when the temperature measured by the safety temperature sensor reaches a predetermined temperature value.
  • the value for the temperature supplied by the safety temperature sensor also indicates whether gas flows through the fluid tube, since in this case the heating heat is transported through the fluid medium to the outer peripheral portion of the fluid tube.
  • a second temperature sensor is provided at an outlet of the fluid tube.
  • the temperature value determined by the second temperature sensor is advantageously used to regulate the heating power.
  • the radiator is advantageously an infrared radiator and the fluid tube is made of stainless steel, a ceramic tube or a steel tube lined with ceramic or a ceramic tube. As a result, a large part of the thermal energy emitted by the radiator is reflected back into the fluid tube on the inner circumference of the fluid tube.
  • FIG. 1 shows a schematic illustration of a first exemplary embodiment of a fluid heating device according to the invention.
  • FIG. 2 shows a cross-sectional view of a second exemplary embodiment of a fluid heating device according to the invention.
  • FIG. 1 A first exemplary embodiment of a fluid heating device 1 according to the invention is shown schematically in FIG. 1.
  • the fluid heating device 1 has a fluid tube 2 through which a gas (not shown) flows, the direction of flow being shown by the arrows in FIG. 1.
  • a quartz tube 3, which has a heating wire 4, is arranged concentrically in the fluid tube 2.
  • the heating wire 4 has two lead wires 5, 6, which are guided to the outside through passages in the quartz tube 3 and the fluid tube 2. By applying a voltage to the lead wires 5, 6, the heating wire 4 is supplied with energy and emits in particular IR heating power, which heats the gas flowing in the direction of the arrow in the flow process.
  • a safety temperature sensor 7 senses the temperature on the outside of the quartz jacket 3 in order to switch off the heating device in the event of overtemperature.
  • a second temperature sensor 8 analogously senses the temperature of the gas downstream of the fluid heating device 1. The value of the temperature measured by the second temperature sensor 8 can be used to control the electrical power applied to the heating wire 4 via the lead wires 5, 6 in order to keep the temperature of the gas constant.
  • the fluid heating device 1 has a fluid tube 2 made of polished stainless steel, in which a gas (not shown), such as N 2 gas, flows. The direction of flow is indicated by the arrows.
  • the gas enters the tube 2 through an inlet 9 arranged transversely to the fluid tube 2 and exits through an outlet 10 likewise offset transversely to the fluid tube 2 and the inlet 9.
  • a quartz jacket is arranged axially symmetrically, which is designed as a quartz tube 3, which extends beyond the inlet 9 and the outlet 10.
  • a heating wire (not shown) is arranged over the schematically indicated length L in a section 11 of the quartz jacket 3, to whose supply wires 5, 6 an electrical voltage is applied in order to heat the heating wire.
  • the lead wires 5, 6 are guided in the quartz tube 3 and are led out of the fluid tube 2 at the quartz tube ends.
  • the points at which the quartz tube 3 emerges from the fluid tube 2 are provided with sealing devices 12, 13 on the inlet side 9 and outlet side 10, which are preferably designed as sealing rings.
  • the safety temperature sensor 7 feels that Temperature on the outer circumference of the fluid tube 2 from.
  • a second temperature sensor 8 senses the gas temperature downstream of the heated section 11 of the quartz tube 3 on the outer circumference of a tube that conducts the fluid.
