Definitions
- the present invention refers to a radiating and convection element preferably intended to be arranged below a ceiling and of the kind comprising an elongated ventilation duct, to both sides of which a battery housing is connected, said battery housing is open upwardly and downwardly and is provided with a convection battery.
- Radiating- and convection elements of this kind are previously known and are used either for heating or cooling of premises or for air conditioning.
- a disadvantage of the known radiating- and convection elements is that they are relatively expensive to manufacture and another disadvantage is that they may not easily be adapted to present needs, e.g. by variation of the width of the ventilation duct.
- the object of the invention is at first hand to provide a radiating- and convection element, which is not impaired by these disadvantages and which consists of simple, less bulky parts, which in a simple way can be connected to each other in situ and maintaining a good heat-conducting contact between the parts of the element.
- the element is composed by separate parts, a bottom plate, which is common for the ventilation duct and the battery housing and which plate has a longitudinal rim, a partition wall common for the duct and the respective battery housing and which with a bent portion is intended to engage said rim, a top plate provided with side flanges and connectable with the upper end portion of the partition walls and an outer wall laterally defining each battery housing, said outer wall being fixed to the partition wall by means of a number of upper and lower binding clamps while simultaneously clamping the convection battery between said walls.
- the radiating- and convection element comprises a ventilation duct denoted with the numeral 1 and which is built together with one or more upwardly and downwardly open element housings denoted 2a, 2b and which each are provided with convection batteries 30,31.
- the ventilation duct and the element housings are arranged in a way so that an air stream passing through the ventilation duct by means of ejector effect provides an air stream downwardly through the element housings.
- the bottom plate of the ventilation duct 1 consists of a plate 4, which at its ends is bent to form two rims 5a,5b.
- the side walls of the ventilation duct consists of plates 6, which each has a vertical portion 7, which downwards passes into a horizontal portion 8, which is terminated by an upwardly directed portion 9.
- the vertical portion 7 passes upwards into a horizontal portion 10 extending in the opposite direction to the horizontal portion 8 and which is terminated by a downwardly directed portion 11 (see also fig. 6).
- a profilated plate 12 is attached for example through point welding and which has a vertical portion 13, which passes downwards into a horizontal portion 14 and upwards into an upper horizontal portion 15, which passes into an oblique portion 16.
- the upper side 17 of the ventilation duct consists of a plate 18, which has its free ends perperdiculary bent to form flanges 19a,19b, which for example through point welding are attached to the side walls 7 with the upper portions of the flanges contacting the upper portions 10 of the sidewalls 6.
- a passage is formed between the upper portion of the ventilation duct 1 and the upper portion of the element, which passage can receive electric cables and the like.
- the ventilation duct further has end fittings 20, one of which has a number of outlet openings 21 while the other has a connection piece 22 (see fig. 4) through which air from a fan (not shown) is forced through the ventilation duct.
- the throttling of the air stream through the ventilation duct mentioned above is of course determined to its size by the number of openings 21 and their dimensions.
- the element housings 2a, 2b have an inner side wall which is common with the respectve outer wall of the ventilation duct and an outer side wall 23, which has the shape of a profile, preferivelyably an extruded aluminium profile.
- This has a vertical portion 24, which passes downwards into a substantially horizontal portion 25, which is terminated by a male portion 26 in the form of a notch. Between the ends of the vertical portions 24 it forms a projecting web 27 and upwards it forms a horizontal portion 28, which passes into an oblique portion 29.
- the distance between the portion 28 and the portion forming the web 27 corresponds to the distance between the upper and lower horizontal portions 14,15 of the profile plate 12 and substantially corresponds to the height of the convection element 30.
- the plates consist of plane plates which have holes for guiding a pipe 31 for for example a cooling medium.
- the plates can have pressed stiffening webs 32 and have two opposite edges portions perpendicularly bent to form flanges 33a,33b.
- the convection elements are placed close to each other at which the height of the flange 33a,33b will be determined by the distance therebetween.
- first binding clamp 34 preferably consisting of plate strips 35, which are obliqely bent at their free ends to form oblique flanges 36a, 36b intended to engage the oblique portions 29 and 16 (see fig. 1) and a second binding clamp 37 obtained by cutting an extruded profile 37, which is substantially L-shaped with a rib portion 38 provided with a raised portion 39 in which a number of attachment holes 40 are located.
- the rib portion 38 has an extended portion 41 at one flange 42 of the profile and the flange is terminated by a hook portion 43.
- the other flange 44 of the profile is terminated by a female portion 45 intended to cooperate by snap-action with the male portion 26 of the side wall profile 23.
- the outer part of the hook portion 43 has a height substantially less than the internal height of the rim 5a,5b with the thickness of material of the lower horizontal portion 8 of the side wall 6 and through the oblique surface of the hook portion shown in fig. 6 the binding clamps 37 can be hooked into the bottom plate after the lower portion 8 of the side wall has been inserted into the rim 5a and 5b respectively.
- the binding clamps 37 are intended to be fixed to the wall portion 7 by means of self tapping screws through the holes 40 and the wall portion 7 can for this purpose have a number of tiny holes.
- the mounting of the element housing is done by placing the convection battery consisting of the convection elements 30 and the pipe 31 in its position, after which the binding clamps 37 are attached according to fig. 1, that is engaging the oblique portions 29 and 16 and snap locking of the lower portion is done by snapping the male portions 26 together with the female portions 45. Since the binding clamps 34 and 37 are narrow the element housings will be open upwardly and downwardly and the different parts of the elements will be kept permanently pressed against each other at which a good heat conduction between the different parts is ensured.
- the above described radiating- and convection element can by that mainly be mounted in situ in a simple way and the parts contained therein can be produced at a low price.
- the side wall 6 is in the embodiment shown i fig. 2 replaced by a side plate 6′, which has a goose necked portion at 46 but lacks the bent upper portion 10,11.
- the bent portion 19a and 19b respectively of the upper wall of the ventilation duct continues in a portion 47 engaging the upper edge portion of the side wall and by that makes an oblique angle so that it can be engaged by the binding clamp 34′.
- This radiating- and convection element can by that be delivered in parts and is very little bulky and the mounting consists besides the tightening of the binding clamps 37 only of jointing and snapping operations.
- the upper part of the ventilation duct has the same shape as in fig. 1 but the side wall has and oblique part 49 engaging the part 19a and 19b respectively, which in turn is engaged by the respective binding clamp 34′ ⁇ .
- the ventilation duct 1 can be provided with heating or cooling stripes.
- holders 50 for pipes for a heating or cooling medium are attached at the under side of the ventilation duct.
- For suspending the unit holes 52 for ceiling attachments can be arranged according to fig.5. Only one side of the element has been described above but as can be seen from the drawing figures an embodiment is intended according to which an element housing 2a is connected to one side of the ventilation duct and a second element housing 2b is connected to its other side, but also single sided arrangements as well as other combinations are of course possible.
- the bottom plate 4 can be perforated and it can also have a chute for attachment of fluorescent tubes and the like.
