Definitions

  • the invention relates to an installation part for mixing chambers of fluidic systems with the features of the preamble of patent claim 1.
  • Such mixing chambers have as part z.
  • B an air conditioning system the task of mixing at least two partial flows, the outside air and the recirculating air, which generally have different temperatures, on the shortest possible route.
  • the hollow body In a known mixing chamber of the type mentioned (DE-PS 32 17 803), the hollow body has an elongated cross section. On an upstream side, the hollow bodies are closed 90 degrees to their axis of symmetry, while the outlet cross section is provided exclusively on the side which faces the outlet for the main flow.
  • the mixing chamber known from DE-PS 32 17 803 has proven itself in operation, but the degree of mixing can be improved still further.
  • the hollow bodies that carry a partial flow are specially shaped components, for which suitable tools have to be used.
  • the object of the invention is to make the generic built-in part of the mixing chamber simpler and cheaper and to achieve a better mixing of the partial flows.
  • hollow bodies can be assumed, preferably round tubes, which are available as semi-finished products.
  • the built-in part can therefore be manufactured more cost-effectively.
  • there is a fluidic advantage due to the better mixing of the partial flows since many small partial flows during Passage through the pipes on defined paths to the outlet are inevitably better guided and thus better mixed, the guided length of a partial stream decreasing in a targeted manner in the flow direction of the main stream or alternatively increasing or equivalent, the air outlet surfaces of the hollow bodies becoming larger in the main flow direction with partial streams of the same length, or alternatively, the air outlet areas of the hollow bodies become smaller in the main flow direction.
  • the mixing chambers of fluidic systems are delimited by two side walls 1, a lower and upper base plate 2 and an end wall 3.
  • the mixing chamber is usually provided with two inlets 4, 5 for two partial air flows and with a common outlet 6.
  • At the inlets 4, 5, flow channels, not shown, are connected, in which, in a manner known per se, built-in components, for. B.
  • Venetian blinds are arranged to regulate the incoming air volume flows.
  • the inflow directions of the partial flows 7, 8 from the circulating air and outside air indicated by the arrows are at an angle of approximately 90 degrees to one another. Other inflow arrangements are also possible.
  • the partial streams 7, 8 supplied are combined in the mixing chamber and leave the mixing chamber through the outlet 6 as a combined main stream 9.
  • the further components of an air conditioning system for. B. filters and heat exchangers, which are not shown here.
  • one partial stream 7 is supplied from above, it can also be introduced into the mixing chamber laterally or from below.
  • the inlet 5 is provided here in the upper part of the end wall 3 of the mixing chamber, it can also be arranged lower or below.
  • hollow bodies 10 are arranged at a distance from one another, which are parallel to the direction of flow of the one partial flow 8 or the main flow 9. In adjacent rows, the hollow bodies 10 can be aligned in a line transversely to the flow direction of the one partial stream 8 or offset from one another.
  • the hollow bodies 10 flow around one partial flow 8 and flow through and around the other partial flow 7.
  • the hollow bodies 10 protrude freely into the associated inlet 4, so that the partial stream 7 supplied through this inlet 4 enters the mixing chamber between the hollow bodies 10 and divided into individual jets from the hollow bodies 10 and is intensively mixed there with the other partial stream 8 and as combined main stream 9 leaves the mixing chamber.
  • the hollow body 10 of a row are together, for. B. connected by screws, each penetrating the hollow body walls of two adjacent hollow bodies 10 in the upper part. At the ends of the rows, the first and last hollow bodies 10 are fastened to a bar.
  • the hollow bodies 10 preferably have a round cross section. But other profiles, e.g. B. oval tubes or as shown in Fig. 7 and 8, half-shell profiles 10b can be used. These half-shell profiles 10b are arranged in such a way that their closed-walled part faces the inflow of the one partial flow 8, while the open part lies on the outflow side.
  • the length of the individual jets generated by the hollow body 10 from the one partial stream 7 is to change in the flow direction of the main stream 9.
  • the length can change continuously or discontinuously in jumps or along a straight or curved curve.
  • the length of the hollow bodies 10 projecting into the partial stream 8 decreases in the flow direction of the partial stream 8 or the main stream 9 flowing into the hollow bodies 10.
  • 1a, 2a, 3a show, for example, that the change in length of the individual hollow bodies 10 can also take place in reverse to FIGS. 1, 2, 3, so that the hollow bodies 10 increase in length in the flow direction of the main stream 9. This principle also applies to all versions described below.
  • the hollow bodies 10 can, however, also be of the same length for design reasons, in which case the hollow bodies 10 are provided with air outlet surfaces 10a on the outflow side in order to generate individual beams of unequal length. These air outlet surfaces 10a become larger from the inlet 5 in the direction of flow of the main stream 9, as shown in FIGS. 4 and 5 for example. Alternatively, the air outlet surfaces 10a of the hollow body 10 from the inlet 5 in the flow direction of the main stream 9 can become smaller, such as. B. in Fig. 4a and 5a.
  • the geometric shape of the air outlet surfaces 10a can be designed in different ways.
  • FIG. 9 shows a mixing chamber with two built-in parts made of hollow bodies 10, which each protrude into an inlet 4 and 5a.
  • two partial flows 7 and 8a are supplied, each of which consists of a part flowing around the hollow body 10 and a part flowing through the hollow body 10 and divided into individual jets.
  • Both partial flows 7 and 8a flow here at an angle of 90 degrees (can also deviate from 90 degrees) to the flow direction of the main flow 9 through the inlets 4 and 5a into the mixing chamber, are deflected in the flow direction of the main flow 9, mixed with fine strands and left the mixing chamber through the outlet 6, to which other components such as air filters, preheaters, etc. are usually connected.
  • the end wall 3 is closed in FIG. 9.
  • the position of the inlets 4 and 5a, including the adjoining hollow bodies 10, can be arranged with respect to one another in the side walls 1 and / or the base plates 2, and also together only in one side wall 1 or only in one base plate 2.
  • FIG. 10 shows a mixing chamber similar to that in FIG. 9 with two built-in parts made of hollow bodies 10 and an additional inlet 5.
  • This mixing chamber is able to mix the three partial streams 7, 8 and 8a with a high degree of mixing.
  • This mixing chamber is a combination of the embodiments according to FIGS. 1 to 8 and FIG. 9.
  • the inlets 4 and 5a can be arranged as desired, as described in FIG. 9.
  • the inlet 5 can be attached in the end wall 3 in height and size.
  • the end wall 3 can also be omitted entirely if the inlet 5 is the same size as the end wall 3.
  • the inlets 4 and 5a are offset in FIG. 10, they can also be directly opposite.
  • the hollow bodies 10 arranged in a row are then laid at greater intervals, so that the hollow bodies 10 are toothed and alternately a row of the inlet 4 and 5a lie one above the other in a space-saving manner.
  • the hollow bodies 10 of the built-in parts according to FIGS. 9 and 10 preferably consist of round tubes, but they can also be designed as shown and described in FIGS. 1 to 8 and FIGS. 1a to 5a.
  • the individual hollow bodies 10 of a row of hollow bodies can be formed by partitions 10c within a common outer wall 10d, such as, for example, B. in Figs. 11 and 12.
  • the partial flows 7 and 8a preferably flow through and around the hollow bodies 10, that is to say that the spaces between the rows of hollow bodies are open in inlets 4 and 5a.
  • these spaces can also be partially or completely closed.
  • the inlets 4, 5 and 5a are provided with perforated shutters in order to even out the inflow profiles and thus to achieve a better degree of mixing.
  • the hollow bodies 10 are perforated in the rear area to the direction of flow of the main stream 9. This ensures that the partial flows are mixed even better.
  • the exit surfaces 10a of the hollow body 10 also achieve better mixing with perforated sheet cover in certain cases.
  • the hollow bodies 10 are divided in length and telescopically displaceable. In this way, the distance of the air outlet openings 10a from the base plate 2 can be adjusted in order to vary the length of the individual jets emerging depending on the inflow conditions. An adaptation to unforeseeable inflows can also be made in that the air outlet openings 10a of individual hollow bodies 10 can be closed.
