Definitions

  • the present invention refers to a heating- and/or cooling baffle, in the form of panels of the type which, includes at least one pipe for a heat emitting or heat-absorbing flow medium, which pipe is in heat conducting contact, with longitudinal flanges protruding therefrom, whereby at least some of the panels are provided with transverse gill-shaped slits.
  • cooling panels It is a known fact, that the cold surfaces, placed horizontally in a roof, so called cooling panels, give a much better climate.
  • the high radiation ratio of the cooling panels makes that the air movements in the room can be held on a minimal level.
  • it has been designed as cooling baffles, shaped at the top and at the bottom as open boxes, in which at least one cooling battery is arranged and which baffles are run through by room air.
  • the cooling baffle consequently emits its power through convection, which causes relatively high air movement and problems with draught.
  • a cooler baffle must consequently use both radiation and convection.
  • the purpose of the present invention is to produce constructively simple and inexpensive producable baffles, which are designed such that, as under-roof-baffles, they emit one part of its power through convection in such a way, that strong downward airflows under the baffle do not appear.
  • These objects have been achieved by, a number of panels along the side-edges of the flanges being connected to each other, forming the walls in a baffle-drum, and that in some of the walls, the flanges of the panel and the panels respectively, along at least one part, at their length provided gill-shaped slits, while the panels in the remaining walls are not slit.
  • Fig.1 shows a sectional plane view of a simple panel according to a known design.
  • Fig. 2 shows a section along the line II-II in fig. 1.
  • Fig. 3 shows a section along the line III-III in fig. 1.
  • Fig. 4 shows a section through one of four panels, comprising a baffle according to the invention.
  • Fig. 5 is a modified embodiment of the application shown in fig. 4, with six panels involved.
  • Fig. 6 shows a longitudinal section along the line VII-VII in fig. 4.
  • Fig. 7 shows in a larger scale, a bottom view through a cooling baffle, of same type which is shown in fig. 4, with connection profiles at the baffle's corner and with an inner stay.
  • Fig. 8 shows a section of a further embodiment, which section is analogous to that of fig. 5.
  • the figures 1, 2 and 3 show a heating- and/or cooling baffle 12, pereferably of the type which is described in SE 7800864-6, and which consists of a pipe 13 and longitudinal flanges 14 protruding from this, located essentially at the same level.
  • the flanges 14 are along at least a part of their length, provided with transverse, gill-shaped slits 15, the gills 16 of which connect to the flange, with a soft rounding 17.
  • the total length L of the slit 15 is preferably twice as big as height H of the slit.
  • the pipe 13 preferably is constituted by a thin copper pipe, which is located between two thin aluminium sheets, which subsequently are coldwelded together, so that an intimate permanent connection between these three parts is achieved.
  • baffle in this connection generally is referred to a plate, a box or the like, intended for guiding a gas flow.
  • a number of panels 12 can be composed to box-shaped units 21 as shown in figs. 4 and 5.
  • fig. 4 four panels have been connected together, forming in cross section, a rectangular shape
  • the embodiment according to fig. 5 shows a baffle composed of six panels 12.
  • the horizontal walls -the panels 12 - of the baffle are made in accordance with the invention, ie. provided with gill-shaped slits 15, while the vertical walls, which as well consist of panels, are not slit, ie. they lack the gill-shaped slits 15.
  • the baffle can be shaped as it appears in fig. 6, where in the baffle's 21 one front gable 22 a pipe socket 23 may be provided, for connection of supply air. If necessary, a damper 24 can be arranged in the pipe socket.
  • the baffle's 21 upper horizontal panel 12a the gill-shaped slits 15a are provided only in that part of the baffle, which is adjacent to the front gable 22, while in the lower, horizontal panel 12b gill-shaped slits 15b and 15c are provided, connected to the front gable 22 as well as connected to a back gable 25, at the baffle's opposite end.
  • the gable 25 seals the baffle's end completely, so that the supply air entered through the pipe socket 23, is forced to turn against the gable 25, and flows out through the slits 15c at an angle corresponding to the angle of the gills against the flanges 14. This angle should be 30 - 60° pereferably 45°.
  • the supply air entering into the baffle also entails, that the room-air is coejected through the slits 15a and 15b, which are located immediate to the intake pipe-socket 23 for the supply air.
  • the embodiment shown in fig. 7 refers to a baffle 21 of same type shown in fig. 4, but in contrast to this, the variant shown in fig. 7 is composed of profiles, pereferably aluminium profiles, which makes it possible, by means of snap-in locks, to assemble the panels forming a baffle.
  • a corner-profile 26 which essentially is U-formed and at whose one shank, a seat 27 for receiving a tongue 28, placed at an inner, frame-shaped stay 29, is provided.
  • the stay 29 in contrary to the corner-profiles 26, which extend along the entire baffle, is only some centimetre wide and positioned with an appropriate mutual distance, which depending on the length of the baffle, can be between 1/2 to 1 meter.
  • the inner stay 29 is also provided with resilient, notch-shaped snap-in means 30, which cooperates with corresponding notch-shaped snap-in means 31, developed as extensions of the seat 27.
  • the baffle can consequently be assembled for instance, of four panels, two shaped with gill-shaped slits and two non slit. The latter are at their free end-sections 32 bent in 90° angle, so that these end-sections overlap corresponding end-sections of the horizontally located panels 12a and 12b.
  • the assembly is done by placing the angled end-sections 32 of the baffle's flanges 14 in the corner-profiles 26, after which the frame-shaped stay 29 with its tongues 28 is placed in the seats 27, whereby the snap-in profiles 30 and 31 also hook into each other.
  • connection of the feeder (not shown) and the pipe bends 18, to the baffle's 12 pipes 13 is done by flaring these at the end-sections of the baffles so, that they obtain circular cross section, whereby a connecting-pipe or pipe bend can be fixed by soldering.
  • the embodiment shown in fig. 8 differs from the one shown in fig. 5, by gill-shaped slits 15 being machined in the vertical baffles 12c, while the horizontal baffles do not have similar slits.
  • This type of baffle 21 can be used conveniently both as heating or cooling baffle, and for this purpose the horizontal, lower panel's pipes 13 are suitably connected to a heat-emitting medium and the pipelines 13 to the upper horizontal panels 12a and the vertical panels 12c are connected to a heat-absorbing medium.
