Definitions
- the present invention relates to a device for heating a fluid.
- the fluid is, for example, a liquid such as domestic water or a gas such. B. Air.
- the respective fluid is placed in a container to z. B. to function in the manner of a boiler in the case of liquids, a stratification of the fluid must be observed.
- the layers relate to the components of the fluid at different temperatures and the resulting different densities in the container. If, for example, a warm liquid is fed into a container from above, which has a downward velocity component, then as a rule several layers are mixed. This is also relevant for removal from the container: e.g. B. a warm layer can not be completely removed in a removal at an upper point of the container. If, for example, cold liquid flows in at another point at the upper end of the container (e.g.
- the object on which the invention is based is to propose a device for heating a fluid which is characterized by the most optimal possible stratification of the fluid in a container.
- the invention achieves the object by means of a device for heating a fluid, having an energy unit, a heat exchanger and a container, the energy unit generating thermal energy, the heat exchanger generating heat from the energy unit thermal energy generated is transferred to the fluid, with the container receiving the fluid, with at least one deflection device being present for introducing fluid into the container and/or for removing fluid from the container, with the deflection device having a ring element which guides the fluid , wherein the ring element has a longitudinal opening, and wherein the opening connects an interior space of the container with the deflection device.
- the device according to the invention for heating a fluid has an energy unit, a heat exchanger and a container.
- the energy unit generates thermal energy - for example by burning a fuel-air mixture or electrically.
- a heat exchanger transfers this thermal energy to the fluid.
- the fluid is, for example, a liquid or a gas.
- the thermal energy is transferred jointly or alternately to a liquid—particularly water—and air—particularly room air.
- the fluid is received by a container. Depending on the configuration, this involves fluid that is to be heated or fluid that has been heated.
- the deflection device which deflects the fluid in such a way that it does not mix an existing stratification in the container or that the fluid removed from the container originates from only one stratum.
- the deflection device has a ring element.
- the fluid is thus guided in a ring and preferably only in one plane.
- the ring element has an opening on the longitudinal side, via which the fluid can flow from the ring element into the interior of the container or from the container into the ring element.
- the fact that it is a longitudinal opening means that the opening is e.g. B. is located along a jacket of the ring member. It is therefore in particular not a front opening as z. B. is given in hoses or tubes in the rule.
- the ring element is provided with an opening on the side over at least part of the longitudinal extension.
- the longitudinal opening is located in particular on the side of the ring element which faces a center of the ring element or a longitudinal axis of the container. The opening is therefore on the inside of the ring element.
- the fluid leaves the ring element laterally and inwards, so that the fluid is located and moves accordingly in the plane in which the ring element is arranged.
- This can also be formulated in such a way that the fluid flows laterally out of the ring element into the interior of the container or that the fluid is discharged laterally.
- the ring element according to the invention causes good stratification even with flat containers that may not be cylindrical, but z. B. are cuboid.
- the longitudinal opening is designed in the form of a slit.
- the opening thus encompasses a larger angular range of the ring element.
- the height of the slot is addressed in the following embodiments.
- the ring element is designed in one piece with an end face of the container.
- the ring element is, for example, part of the lid or the base of the container.
- the end face of the container is curved in the direction of the interior at least in a region encompassed by the ring element.
- the end face on which the ring element is located is therefore inclined inwards in this configuration.
- the curvature supports a low mixing of the different fluid layers. If the fluid is introduced, for example, in the area of the cover, the fluid flows after leaving the ring element in the cover along the z. B. designed as an oval interior of the ring member instead of flowing straight to the center of the container.
- the end face is curved away from the interior space in the encompassed area.
- the area of the end face which is surrounded by the ring element is curved inwards, and the area of the end face which adjoins the ring element on the outside is designed flat or curved away from the interior of the container.
- the ring element is self-contained.
- the ring element does not have an opening at the end.
- the fluid thus enters and exits the ring element only via the longitudinal opening or possibly several longitudinal openings. Otherwise the fluid circulates completely in the ring element.
- a transition of the self-contained ring element is only given via one of the following configurations in the form of a connection element.
- the longitudinal opening extends completely around the ring element.
- the opening on the long side extends only partially around the ring element.
- the longitudinal opening thus extends completely over an inner side of the ring element or only over a part.
- connection element is present, that the connection element is arranged outside of the container, and that the connection element and the ring element are coupled to one another such that the fluid can flow between the connection element and the ring element.
- the fluid thus enters the annular element or the fluid exits the annular element via the connection element.
- the connection element is located in particular outside of the container.
- connection element opens out on that side of the ring element which faces away from the longitudinal opening. So this is the outside of the ring element.
- connection element consists in the connection element guiding the fluid tangentially to the ring element or discharging it from the ring element.
- the fluid is thus either introduced laterally into the ring element or removed from it. This depends on usage.
- the ring element has an oval shape.
- the ring element has a large semi-axis and a small semi-axis.
- the transition between the connection element and the ring element is located along the semi-major axis of the oval.
- An oval that is as large as possible has the advantage that the velocity component perpendicular to the plane of the oval is very small.
- the kinetic energy of the fluid flow could already dissipate in the oval and thus does not cause any unwanted turbulence with fluid from other layers.
- the ring element has a circular shape.
- One configuration is that a side wall of the container is connected to the ring element in a first connection area, with an end face of the container being connected to the ring element in a second connection area, and the opening extends from the first connection area to the second connection area.
- the ring element is connected to the container or the ring element merges into the container.
- the ring element is connected to a side wall and to an end face, or the container has a structure in which a side wall and an end face merge into the ring element.
- the longitudinal opening which is preferably designed as a slit, extends between the two connecting sides on the ring element, ie between the side wall and the end face (ie, for example, the lid or base of the container).
- a longitudinal web is arranged on the first connection area or on the second connection area, and the web partially closes the opening.
- the longitudinal opening is at least partially narrowed by having a web. The web thus extends around the longitudinal side of the ring element and reduces the opening angle of the opening.
- the web or, in other words, the projection is a separate component or is part of the ring element itself.
- the web only extends over part of the longitudinal opening and/or has a variable extent.
- the height of the longitudinal opening is not constant but varies along the ring member. This allows z. B. depending on the respective radius of curvature of the ring element, how much fluid can leave or flow into the ring element.
- the two deflection devices there are two deflection devices, with the two deflection devices being assigned a common direction of rotation.
- the two deflection devices are, for example, once on the lid and once on the bottom of the container.
- the fact that both deflection devices are assigned a common—or the same—direction of rotation means that the fluid in both deflection devices rotates in the same direction—that is, either to the left or to the right. Will thus have a
- the fluid is introduced into the deflection device and removed via the other deflection devices, so the risk of turbulence in the temperature layers is countered via the same/common direction of rotation.
- the direction of rotation in the deflection devices results in particular from the position and contacting of the respective connection element.
- the fluid is a liquid, e.g. B. domestic water is.
- the individual components and their connections are therefore suitable for drinking water in this configuration.
- the energy unit generates thermal energy by burning a fuel-air mixture and/or by converting electrical energy.
- the thermal energy is generated by burning a fuel, e.g. B. combustible gas or diesel fuel converted into the gaseous state, or generated by the conversion of electrical energy.
- FIG. 1 shows a schematic representation of a device for heating a fluid
- FIG. 2 shows a spatial representation of a container with two deflection devices
- Fig. 3 shows a section through the container of Fig. 2
- FIG. 4 shows an enlarged section of a container with three superimposed alternative designs of a deflection device
- Fig. 5 is a spatial representation of a container with two deflection devices with a further variant
- Fig. 6 shows a sectioned part of the container of Fig. 5.
- 1 schematically shows the structure of a device for heating at least one fluid.
- the device heats z. e.g. water and air.
- the ring elements 41 are self-contained, so that the fluid can circulate in them except for the lateral openings 42 .
- the transition between the ring elements 41 and an outer - not shown here - periphery, z. B. in the form of hoses or tubes, etc., the connection elements 40, which each merge tangentially into the ring element 41 are used.
- the fluid is only guided in a straight line here. So, for example, via a connection element 40, the fluid in the container 3 introduced, it initially moves only linearly, then enters the ring element 41 and is guided there in an oval.
- the ring elements 41 include a circular area. Furthermore, the connecting element runs perpendicularly to the large longitudinal axis of the container 3 and not--as in FIG. 2--parallel thereto.
- the opening 42 is significantly smaller in that a lower area of the cylindrical ring element 41 extends further, starting from the first connection area 43 .
