Definitions

  • the invention relates to a device for heating a liquid with at least one liquid container for separating gas from the liquid and with at least one heat source for generating thermal energy for heating the liquid.
  • the device for heating a liquid is, for example, a water heater or part of a heater.
  • the liquid is, for example, water or a water / glycol mixture or any heat transfer medium.
  • Bubble or air separators are used to remove gas bubbles or especially air bubbles from a liquid.
  • Such bubble separators usually have a container with inlets and outlets for the liquid and with a gas outlet.
  • the gas bubbles rise from the liquid and collect in a space above the liquid.
  • the gas that collects above the liquid is usually discharged from the bubble separator via a line. This generally results in a fixed orientation of at least the gas outlet, so that only the gas and not the liquid can escape through it.
  • Exemplary bubble separators for cooling water circuits of vehicles are disclosed in DE 36 21 837 A1 or 10 2006 014 400 A1. These require a fixed orientation of the container relative to the earth's gravity field.

  • Alignment relative to the earth's gravity field should preferably take place along the orientation axes, however, with sufficiently large distances between the mouth areas, a certain tilting is also possible within several angular degrees, so that the respective orientation axis can also be slightly inclined to the earth's gravity field.
  • the invention relates to a device that heats a liquid, for which a heat source and a liquid container are present.

  • This common partial volume is one of eight partial volumes.
  • the eight partial volumes describe the entire inner volume of the liquid container. These are, in particular, imaginary partial volumes that only serve to locate the components.
  • the partial volumes are obtained by determining a center of gravity on the liquid container from three view sides. The three view pages are perpendicular to each other. A common name for three such views is e.g. B. Front view, side view and top view.
  • a center of gravity is determined for each view and two parting planes are laid through the centroid of the surface, which intersect at an angle of 90 ° in the respective centroid of the surface. All three pairs of parting planes define the partial volumes. Here are at a z. B. cuboid liquid container, the two parting planes of a focal point and a parting plane of a further focal point are sufficient, since these parting planes coincide with the other three parting planes.
  • the liquid feed line and the liquid discharge line open together in one of these partial volumes.
  • orientation axes are the axes that allow the alignment of the liquid container. These are therefore also the axes along which the earth's gravity field should run when the device is in the assembled state, so that the liquid container functions properly.
  • the ventilation line is higher than the liquid discharge along each orientation axis.
  • the designation “higher” refers to the direction of the orientation axis, which preferably refers to the direction of gravity in the assembled state, ie away from the earth.
  • the device thus has at least two installation positions which allow the liquid container to function in accordance with the regulations. Can in practical use deviations from the orientation to the earth's gravitational field also occur, insofar as the height distance between the ventilation line and the liquid discharge line is sufficiently large for tilting.
  • orientation axes each run in the direction of an assigned view side, and that the vent line opens in the direction of the view side assigned to the orientation axis at a higher level than the liquid discharge.
  • the orientation axes result from the view pages.
  • liquid supply line and / or the liquid discharge line and / or the ventilation line are / are at least partially tubular.
  • the tubes end in the liquid container or end with the outside of the liquid container in a corresponding opening in the liquid container.

  • the division into the sub-volumes is relatively simple.
  • the liquid container has exactly two orientation axes.
  • the vent line is preferably in each case a partial volume, which is located above the common partial volume along the orientation axes. There are therefore two possible partial volumes.
  • the liquid container has three axes of orientation.
  • the vent line is preferably located in the partial volume which is diagonally opposite the common partial volume in all three installation positions.
  • One embodiment includes that a flow deflection device is arranged between the liquid supply line and the liquid discharge line.
  • the flow deflection device prevents the liquid directly from the liquid supply line enters the liquid discharge line and thus delays the flow of the liquid so that the gas can leave the liquid.
  • the flow deflection device is designed in the form of a plate, against which the liquid feed line guides the liquid. It is therefore a type of baffle.

  • the liquid discharge line 3 opens along the first orientation axis 01 below the ventilation line 4. If this arrangement is rotated 90 ° clockwise, the ventilation line 4 continues to open above the liquid due to the length of the tubular extensions -Direction 3.
