Definitions
- the present invention relates to a sectional radiator for heating and a relevant manufacturing method.
- radiators for heating are either made in cast iron or in die cast aluminium, each element has a collecting pipe either at the top or at the bottom which is joined to the collecting pipes of adjacent elements in the composition of the radiator.
- radiator element sections as a result of their manufacturing method, cannot be moulded in forms which would particularly favour heat exchange and therefore better performance.
- the scope of the invention is to eliminate the above mentioned disadvantages, in supplying a sectional radiator which can be made to any dimension and which has better heat exchange properties as compared with conventional radiators, thanks both to the moulding of its elements and to the material of which they are made.
- the sectional radiator according to the invention is made of elements obtained by the extrusion of more than 99% pure primary aluminium. These elements can be obtained in any form and in particular, with a high number of fins, increasing in this way the heat exchange properties which are already good because of the material employed; aluminium being well known as an efficient conductor of heat.
- the radiator elements can furthermore be cut to any length thus making it possible to construct the radiator to any required height without any changes to the manufacturing equipment.
- Each radiator element comprises essentially a central tube for the passage of the heating fluid, around which are formed longitudinal chambers with external fins.
- the various elements are joined together by two collector pipes, one at the top and one at the bottom, provided with holes for joining the pipes to the elements by tubular inserts.
- top and bottom covers with openings can be provided and lateral covers as well.
- a radiator in accordance with the invention illustrated as a whole, as for example in Figures 1 and 3, is indicated globally with reference number (1), and is constituted of several elements (2), which can have practically any height, as shown for example in Figure 6.
- Each element (2) is obtained by extrusion of a primary aluminium alloy and has a shape as shown in Figures 10 and 11, it comprises one or more central tubes (3) and a couple of parallel panels (5) composing the front and back parts of the element, joined between themselves by curved elements (6), joined to the central tubes (3) and fitted with many fins (7) parallel to the panels (5). Like this one has a unit substantially as (1) with two chambers (4) spreading parallel to the central tube (3) and open both at the top and bottom.
- FIG. 7 A schematic is shown in Figure 7 of the fixing of an element (2) to the top collector (8).
- circular holes (13) with flat seated rims are provided in the thickened bottom (12) of the collector and with which the central tubes (3) of the elements (2) are aligned.
- the connection is made with a tubular insert (15) provided with a shoulder (16) for a cylindrical shaped packing (17).
- One end the tubular insert (15) is placed in the hole (13) of the collector (8) and the other end in the tube (3) of the element (2), with the packing (17) partially inserted in the flat seated rim (14) of the hole (13).
- the joining of the elements is achieved by pressure followed by spot welding between elements 2 and 8.
- the collector pipe (8) is made at a length equal to the width of the radiator and is internally threaded (18) at both ends for connection to the fluid supply and for the fitting of a plug or for connection to another collector, whichever is required.
- the top and sometimes the bottom is covered by an element (12) shown in Figure 8 and which has a U shape and a central arrow headed support (19) to slide into the slot (11) provided on the collectors (8).
- Internal tongues (21) are provided at the bottom edges of the element (12) to fix onto the inside of the panels (5) of the elements (1) and as is shown in
- the cover element (12) which for safety reasons is relatively resilient with rounded edges, can be made either in several sections or in one continual piece to cover the whole radiator. Openings (23) are provided in the top of the element (12) (see Figures 1 and 2) and which are placed to correspond with the chambers (4) of the elements (2) such as to facilitate an upward air current towards the top of the chambers.
- Lateral cover elements can also be provided to be snapped onto respective clips (24) provided in opposite positions on the panels (5) of each element (2) (see Figure 10).
- the finished product made in pure 99.7% aluminium and moulded as described, has a higher thermal efficiency than a corresponding conventional radiator, can be produced at lower cost and can be composed into any type or size.
