- the antechamber 4 which has the same horizontal extent as the chamber 2, is closed at the top by a cover wall 8 and laterally also by the front walls 6 and side walls 7.
- the air cooling element has a wide recess 9 with a rectangular cross-section in the center, which is continuous across the front walls 6.
- Each of the front walls 6 has one between its side edge and the recess 9
- Connection opening 10 which serves to establish a connection of the pre-chamber 4 with that of an adjacent air cooling element or an air supply.
- the two connection openings 10 are each arranged on different sides of the central recess 9, so that they are laterally offset relatively far from one another.
- the antechamber 4 is also essentially airtight.
- the front walls 6, the side walls 7, the partition 3 and the top wall 8 are preferably designed as aluminum plates and glued together.
- the cooling wall 1 is preferably a Zmkorplatte, ie a steel plate with a powder coating, which serves as corrosion protection and has a high absorption coefficient for radiation in the infrared range. Its thickness is preferably not more than 1 mm, in particular 0.62 mm. It is part of a trough 11 which has a raised peripheral side wall 12 which surrounds the lower sections of the front walls 6 and the side walls 7 of the chamber 2 with a small distance.
- the side wall 12 has on each side two slots 13, starting from the upper edge and each arranged in an elongated indentation surrounding them, each receiving a screw bolt 14, the m one Bore is screwed into the respective front wall 6 or side wall 7 in such a way that the heads of the screw bolts 14 projecting beyond the edges of the slots 13 clamp the side wall 12 of the trough 11 to the said walls of the chamber 2.
- a circumferential seal is clamped between the lower edges of the front walls 6 and the side walls 7 on the one hand and the tub 11 on the other hand. Due to the fact that the tub 11 protrudes somewhat to the side, it is possible to arrange air cooling elements in such a way that they adjoin one another without gaps.
- connection openings 10 (see FIG. 4) m the front walls 6 are round.
- a sealing ring 15 is attached, the inner edge of which projects freely beyond its edge and the outer edge region of which is clamped between the front wall 6 and a holding plate 16 connected to the same.
- the sealing ring 15 consists of a flat elastic material, preferably neoprene, and lies in the shape of a circular ring in the plane of the connection opening 10.
- an air cooling arrangement 23 each consisting of a plurality of parallel rows of air cooling elements 24a, b, c, d of the type described, is suspended from a fastening device on the ceiling of the space to be cooled (FIG. 3) in such a way that the cooling wall 1 Connect seamlessly or with a defined joint.
- each z. B. correspond to twice the length of an air cooling element, parallel angle 25 (see FIG. 4) fastened, each with a horizontal flange 26 and a vertical strip 27 projecting downwards from the same, the several - in the illustrated case there are two - of
- Spaces 28 form separate wide tabs 29, which have approximately C-shaped lateral recesses 30 on the side edges.
- Rails 31a, b of C-shaped cross-section are laid through recesses 30 of consecutive angles 25 lying in a line. They are fixed and positioned on the underside and laterally by stops formed by the edges of the recesses 30. So that the rails 31a, b can be inserted in the slightly twisted state m, the recesses 30 are designed so that the rails 31a, b have some play vertically. They are then fixed in each case by means of a screw bolt 32, which is screwed into a threaded hole in the flange 26 and lowered until it presses with its lower end against the upper side of the rail 31a, b.
- the outer leg of a rail 31a, b forms (FIGS. 5a, b) a continuous upward-facing support strip 33, which runs through the recess 30 somewhat above the lower edge.
- Each air cooling element is provided at the two ends of the recess 9 with two pairs of opposing retaining cams 34, which are fastened above the bottom of the recess 9 to their rare walls and protrude horizontally into them.
- Each holding cam 34 is z. B. formed by injection molding plastic part and has a base 35 with a protruding support pin 36 and a connecting to the base 35 tab 37, which on the side wall of the
- Each holding cam 34 is attached to an extension 38 of the front wall 6 projecting from the side m of the recess 9 and which is received without play by a channel 39 penetrating the base 35 and the support pin 36. It is therefore reliably fastened in a simple manner.
- the support pin 36 lies on the support strip 33, while the base 35 forms a lateral sliding surface which points against the outside of the outer leg of the respective rail 31a; b and acts as a stop.
- the air cooling element thus has only slight lateral play at both ends with respect to the rail arrangement, but is displaceable in the longitudinal direction along the rails 31a, b.
- the angles 25 are first suspended at a distance from the ceiling, e.g. B. on m the same anchored downward pointing bolt. Then the rails 31a, bm, the recesses 30 are inserted and fixed by means of the screw bolts 32. At one end of the rails 31a, b a z. B. attached as a clamp piece stop. Finally, from the other end, the air cooling elements 24a, b, c, d are pushed one after the other in a row and finally fixed by a further stop attached behind the last one.
- the air cooling elements are preferably of the same design.
- connection opening in the front wall closing the row is closed by an end plate which corresponds to the holding plate 16 but has no opening.
- the air cooling element 24d that has been pushed on last is finally connected to a supply air line by means of a somewhat longer connecting piece 42.
- connection is established in each case by inserting an end piece of a connection nipple 40 (see also FIG. 6) into the connection opening 10 of the air cooling element that was pushed on last.
- the outer diameter of the connecting piece 40 is in each case slightly smaller than the diameter of the connecting opening 10 receiving it, but larger than the inner diameter of the sealing ring 15, which consequently rests on the outside of the connecting piece 40 in a cuff-like manner under elastic expansion such that the connection is essentially airtight . This is supported in operation by the fact that the pressure in the pre-chamber 4 of the air cooling element is slightly above the external pressure.
- connection nipple 40 When the next air cooling element is pushed on, the other end piece of the connecting nipple 40 slides into its connecting opening 10, so that an exactly same tight connection is produced. So that the connection nipple 40 is automatically correctly positioned, it has a circumferential bead 41 in the center, which forms effective stop surfaces against the holding plates 16 of the two air cooling elements and finally lies between them with little play. It is of course also possible to fix the connecting nipple 40 with one of the two air cooling elements or z. B. detachably connectable by means of a bayonet-like device.
- the connection nipple 40 is preferably made of aluminum or steel sheet.
- the bead 41 can be compressed be made. Instead of the bead, a welded or glued ring can also be provided.
- cooling air coming from a cow aggregate and under slight overpressure flows through the supply air line (not shown) into the pre-chamber 4 of the air cooling element 24d and is distributed through the described connections over the pre-chambers 4 of the further air cooling elements 24c, b, a.
- cool air now flows from the antechamber 4 through the air inlet 5 into the chamber 2.
- the air remains in the chamber 2 for a relatively long time on average, so that a heat exchange takes place with the space to be cooled even before it exits.
- the cooling wall 1 between the air in the chamber 2 and the room air is highly effective Wise heat exchanged, which on the one hand contributes to the cooling of the latter in a way that does not cause any disturbing currents, but on the other hand preheats the former so that its outlet temperature is noticeably higher than the temperature when it enters chamber 2, which increases the risk of annoying cold air flows reduced.
- the cooling wall 1, which is kept at a relatively low temperature by the cooling air, also supports the cooling effect by exchanging radiation with the room to be cooled. Because of the low proportion of free cross-section, their effectiveness in this regard is practically undiminished.
- the cooling effect is based on three mechanisms, namely the introduction of colder air into the room to be cooled through the micro-holes in the cooling wall 1, convection on it and heat conduction through it, and radiation exchange of its surface facing the room with objects in the same.
- An air cooling element according to the invention which is essentially the same in its basic structure and its mode of operation, but has a somewhat different design in detail, according to a second embodiment, which is also characterized by low production costs schematically shown in Fig. 7a, b.
- the chamber 2 is also delimited at the bottom by a cooling wall 1, which is designed as described in connection with the first embodiment.
- a cooling wall 1 which is designed as described in connection with the first embodiment.
- it is part of a trough 11 with a raised circumferential side wall 12.
- It is delimited at the top and on the side by a housing 43 with a top wall 8, which has a flat central section which merges on both sides into sloping sections to which vertical side walls 7 connect and with front walls 6, which are provided with connection openings 10.
- a circumferential sealing strip 44 made of foam rubber is clamped between the lower edges of the front walls 6 and the side walls 7 on the one hand and the edge of the cooling wall 1 on the other hand.
- the distance between the bottom row 45c is approximately 3.4 cm - is sufficiently swirled in the chamber 2 so that no air flows directed against the cooling wall 1 occur that could still be felt below it.
- a different installation of the access openings may be the cheapest. So z. B. the bottom row 45c is missing or the passage openings can be concentrated on the top of the partition 3. It is also possible to attach manifold connections, as described for the air cooling element according to the first embodiment, or of corresponding profiles on the underside of the partition 3.
- the air cooling elements are suspended (FIG. 9) in a manner similar to that in connection with the first
- the air cooling elements form air cooling arrangements from rows arranged next to one another, with one row each being pushed onto two rails 31a, b, which are fastened to crossbeams 46 which follow one another in the longitudinal direction at a distance.
- Rails 31a, b have mutually directed, horizontal webs 47 running at a distance below the crossbeams 46 with upward-facing support strips 33, on which short horizontal holding plates 48 of the housing 43 are supported, which on both sides, each adjoining the
- Front panels 6, just outside the inner edge of the sloping sections are attached to the top wall 8.
- a stop plate 49 is fastened in the center on both sides, lying somewhat lower than the holding plates 48, on the sloping section, which is just below the
- the underside of the web 47 is located and the mobility of the housing 43 is limited upwards, so that its height is defined with a close tolerance.
- the cooling wall 1 is held separately, independently of the housing 43.
- clamping rails 50 are arranged on both sides of the air cooling element, which are also suspended from the crossbeams 46 by means of bands 51.
- the clamping rail 50 in each case comprises a sword 52, which is located between two rows of air cooling elements arranged next to one another is such that the outside of the side wall 12 of the tub 11 abuts the same on both sides.
- One edge of the tub 11 is fixed in each case by means of a spring strip 53 which, with a bent-back lower end section, engages under holding cams 54 on the inside of said side wall 12 and presses it against the sword 52.
- connection between the antechambers 4 of two successive air cooling elements of a row is in turn each established by a connecting nipple 40, the outside diameter of which is slightly smaller than the inside diameter of the connecting openings 10 and the antechambers 4. To facilitate its positioning, it has a center between it the peripheral bead 41 lying on the air cooling elements 24a, b. On both sides of the same, it is provided with two sealing rings 15, which are circumferential and are designed as lip seals and are pressed against the inside of the partition 3.
- the housing 43 of the air cooling elements can each be pushed onto the rails 31a, b one after the other, a connection plug 40 being inserted into the rear connection opening 10, the projecting half of which protrudes into the front connection opening 10 of the housing which is then pushed open, so that it moves makes the connection by itself.
- a cover of a similar design is inserted into the front connection opening 10, which tightly closes it.
- the last housing is by means of a funnel-like design which is also similar
- Connection nipple connected to an air supply line.
- Connection nipples, lids and connection nipples of this type are commercially available, e.g. B. at Lmdab, Haynauer Strasse 48-52, D-12249 Berlin.
- the associated trough 11 is then fastened under each housing 43 by pushing the side walls 12 between the sword 52 and the spring strips 53 until the latter engages under the retaining cams 54.
- the sealing strip 44 is clamped between the housing 43 and the cooling wall 1 and the chamber 2 - apart from the micro-holes in the cooling wall 1 and the air inlet 5 - is sealed airtight.
