Abstract
The air duct is particularly intended for an air-conditioning system and consists of interconnected duct sections (1) each having an inner (2) and an outer (3) mantle with a heat-insulating layer (4) between them. These two mantles are cylindrical. The inner mantle may be in aluminium whilst the outer mantle is PVC and the insulation poly-urethane. The mantles are preferably bent from flat sheet material and seam-welded. The sections may be interconnected by adhesive. FL.
Description
" Warmeluchtkanaal."
De uitvinding betreft een warmeluchtkanaal, meer in het bijzonder bestemd voor luchtbehandelingsinstallaties, beter bekend onder de benaming "air-conditioning".
Gekend zijn buisvormige warmeluchtkanalen met vierkante of rechthoekige dwarsdoorsnede die bestaan uit een binnenmantel van metaalplaat, een buitenmantel van metaalplaat en een warmte-isolatielaag die tussen beide genoemde mantels is aangebracht.
Deze gekende warmeluchtkanalen worden gevormd uit
<EMI ID=1.1>
gelegd en een tweede metaalplaat, welke laag en laatstgenoemde plaat op drie plaatsen V-vormig worden ingedrukt, waarbij de aldus gevormde V-vormige groeven een top van 90[deg.] hebben en de itwee vrije boorden van het aldus gevormde geheel onder 45[deg.] worden afgeschuind. Hierna wordt dit gevormde geheel derwijze geplooid dat een vier- of rechthoekig kanaal wordt gevormd waarvan de tegen elkaar aanliggende boorden aan elkaar worden bevestigd.
Een nadeel van zulk een warmeluchtkanaal is dat de rechte vlakken van de mantels van het kanaal steeds lichtjes
<EMI ID=2.1>
de aan te brengen of op elkaar aansluitende delen die het warmeluchtkanaal vormen, slechts met elkaar kunnen worden verenigd door kadervormige verbindingselementen met T-vormige dwarsdoorsnede waartussen een dichtings- en bevestigingsmiddel wordt aangebracht.
Buiten het feit dat deze warmeluchtkanalen het gebruik van kadervormige verbindingselementen noodzakelijk maken om lekken te voorkomen die aanleiding geven tot warmteverlies, hebben zij nog het nadeel dat zij ingewikkeld en betrekkelijk duur van konstruktie zijn.
Om deze nadelen te ondervangen, zijn volgens het voornaamste kenmerk der uitvinding, de binnen- en buitenmantel van het warmeluchtkanaal waartussen de warmte-isolatielaag is aangebracht, cylindervormig uitgevoerd.
Hierdoor is vervorming van het warmeluchtkanaal praktisch uitgesloten, zodat de verschillende in elkaars verlengde liggende of op elkaar aansluitende te koppelen delen ervan, gewoon tegen elkaar kunnen worden gelijmd of gelast, zonder dat hiertussen een kadervormig bevestigingselement moet worden aan-gebracht. Bovendien bieden deze warmeluchtkanalen nog het voordeel dat de fabrikatiekosten ervan betrekkelijk laag zijn en dat de luchtweerstand in deze kanalen tot een minimum wordt herleid.
Deze en nog andere voordelen zullen blijken uit de hierna volgende beschrijving van een verkozen doch geenszins beperkte uitvoeringsvorm van het warmeluchtkanaal overeenkomstig de uitvinding.
Deze beschrijving verwijst naar bijgevoegde tekening, waarin :
fig. 1 een dwarsdoorsnede weergeeft van het warme luchtkanaal overeenkomstig de uitvinding; fig. 2 een zijaanzicht weergeeft van meerdere aan elkaar gelijmde delen die samen het warmeluchtkanaal vormen.
In deze figuren bemerkt men dat het warmeluchtkanaal bestaat uit meerdere achter elkaar aansluitende delen 1, die zowel rechtlijnig als onder een hoek kunnen zijn geschikt.

voorkeur van aluminium en een cylindervormige buitenmantel 3 met grotere diameter en die bij voorkeur van slagvast polyvinylchloride is vervaardigd. De ruimte tussen de twee genoemde
<EMI ID=4.1>
voorkeur polyurethaan. Aldus wordt een betrekkelijk goedkoop, niet vervormbaar en tegen beschadigingen bestand warmeluchtkanaal bekomen. Bovendien kunnen de verschillende delen ervan die op elkaar aansluiten, zonder problemen en lekdicht aan elkaar worden gelijmd, zonder dat tussen deze delen bijkomende verbindingsdelen worden gevoegd. Buiten het feit dat er zich
"Warm air duct."
The invention relates to a hot air duct, more particularly intended for air treatment installations, better known under the name "air-conditioning".
Tubular hot air ducts of square or rectangular cross section are known which consist of an inner jacket of metal sheet, an outer jacket of metal sheet and a heat insulation layer which is arranged between the two said jackets.
These known warm air ducts are formed from
<EMI ID = 1.1>
and a second metal sheet, the layer and the latter sheet being pressed V-shaped in three places, the V-shaped grooves thus formed having a top of 90 [deg.] and the two free edges of the whole thus formed below 45 [ deg.] are chamfered. After this, this formed whole is pleated to form a four or rectangular channel, the abutting edges of which are fastened together.
A drawback of such a warm air duct is that the straight surfaces of the mantle of the duct are always slightly
<EMI ID = 2.1>
the parts to be fitted or connected to each other which form the hot air duct can only be joined together by frame-shaped connecting elements with T-shaped cross section between which a sealing and fastening means is applied.
Besides the fact that these hot air ducts necessitate the use of frame-shaped connecting elements to prevent leaks that give rise to heat loss, they still have the disadvantage that they are complicated and relatively expensive to construct.
In order to obviate these drawbacks, according to the main feature of the invention, the inner and outer sheath of the warm air duct between which the heat insulation layer is arranged are of cylindrical design.
This practically excludes deformation of the hot air duct, so that the various parts thereof which are mutually aligned or mutually connecting can simply be glued or welded together, without a frame-shaped fixing element having to be arranged between them. In addition, these warm air ducts have the additional advantage that their manufacturing costs are relatively low and that the air resistance in these ducts is reduced to a minimum.
These and other advantages will become apparent from the following description of a preferred but by no means limited embodiment of the warm air duct according to the invention.
This description refers to the attached drawing, in which:
Fig. 1 shows a cross-section of the hot air duct according to the invention; fig. 2 shows a side view of several glued parts which together form the warm air duct.
In these figures it is noted that the warm air duct consists of several connecting parts 1 one behind the other, which can be arranged both rectilinearly and at an angle.
<EMI ID = 3.1>
preferably of aluminum and a cylindrical outer jacket 3 of larger diameter and which is preferably made of impact-resistant polyvinyl chloride. The space between the two mentioned
<EMI ID = 4.1>
preferred polyurethane. A relatively inexpensive, non-deformable and damage-resistant hot air duct is thus obtained. In addition, the different parts that connect to each other can be glued together without problems and leak-proof, without additional connecting parts being added between these parts. Beyond the fact that there is
