Description
- 101~303 This invention relates to an improvement to a one-piece radiator-convector.
More specifically the present invention relates to an improvement to a one-piece radiator-convector comprising a central laminar portion the upper and lower edges whereof include two horizontal hollow enlarged portion~, normally united together by a third vertical hollow enlarged portion for circulating heating or cooling fluid, to said horizontal hollow enlarged portions there being rigid equally spaced fins perpendicular to said central laminar portion and extending upwards and downward~, the side fins arranged at opposite ends of the hollow enlarged portion~ being connected together to define the radiator-sidewalls and there being provided panels applied onto the front and rear edges of such fins in order to clo3e at the front and rear the inter-spaces therebetween.
Through this special structure, the radiator-convector is particularly suitable for manufacturing in one piece by diecasting, while the different spacing between those fins which project from the central laminar portion is obtained in a simple manner by adding to or subtracting from the mould special inserts.
The object of the present invention is to provide improvements aimed at performing an actual increase of the ,, thermal yield potentialities of the radiator-convector with-out modifying the external dimension~.
According to the present invention, this is obtained in that in the central part of the radiator-convector at least a housing is provided, for receiving of fans capable of creating an upwards directed air stream which laps both opposite faces of the central laminar portion.

10863(~3 Further features of the invention will be more apparent from the ensueing detailed description of one embodi ment and one variation illustrated by way of example in the accompanying drawing, where:
Figure 1 is a front view of a radiator-convector according to the invention, Figure 2 is a view along the line II-II of Figure 1, Figure 3 is a view along the line III-III of Figure 1, and ~
Figure 4 is a front view of a variation to the -invention.
Making reference to figures 1, 2 and 3, the numeral 1 denotes generally a radiator-convector. That radiator-convector (hereinafter called for brevity ~radiator~) is -preferably a one piece construction, obtained by diecasting of light alloys and comprises a laminar central portion 2 defined at the top and bottom by tubular enlarged portions ~r sleeves 3,4, which are horizontal and parallel to each other for the delivery and return flows of the cooling or heating fluid. The sleeves 3,4 have at their opposite ends respective widenings 5,6, threaded internally for the screw-ing in of fittings, not shown, effective to connect hydraul-ically and mechanically together more radiators adjacent to each other.
From the sleeves 3,4 and more specifically from the horizontal planes extending through the central longi-~, tudinal axes of such sleeves, there project upwards and ~, downwards fins 7,8 uniformly spaced apart and having their tops and bottom~ connected together by bridges 9, 10 which close above and below the radiator. The fins 7,8 comprisetrapezoidal portions the slanting edges 11,12 of which are ; , , , ~ ,,. ~ .:
1~86~03 in view and define the air outlet and inlet openings respectively. ;~
The fins 7,8 extend partially also over the central laminar portion and terminate at the upper and lower edges of quadrangular openings 13,14 formed in the laminar portion itself.
The openings 13,14 are separate from each other by a tubular enlarged portion or vertical sleeve 15 which ; connects together the horizontal sleeves 3,4.
The fins 7,8 which define the radiator at its sides are directly connected to each other such as to make up two sidewalls which extend continuously from the height of the upper bridges 9 to that of the lower bridges 10. The width of the sidewalls, which in the drawing are denoted with 16,17 :~
is greater than the intermediate fins 7,8, thereby they project to the rear and front beyond the plane through the ~ --rear and front edges of the fin~ 7,8. Furthermore, the trapezoidal portions of the ~in~ 7,8 and the brid~es 9,10 form steps which, together with the front and rear edges of the sidewalls 16,17 define seats wherein panels 18,19 are ~
: seated which enclose the radiator at the front and rear and ..
are held in place by screws 20,21 threadably engaged in . threaded holes formed in bosses 22,23 provided in the fins 7,8 directly adjacent the sidewalls 16,17.
Advantageously, the fins 7,8 extending in the same ,;:
vertical centerplane are connected together such as to form a continuous diaphragm 24 which extend~ from the bridge 9 to the bridge 10.
~ From the above description it will be apparent that .- 30 the panels 18,19, the sidewallq 16,17, the intermediate ~ diaphragm 24 define at the openings 13,14 two spaces or seats ;;
,: '',' :,, ` / . ,'~
~086303 in which two blowers 25,26 having vertical axes are installed.
~he blowers are attached to the radiator through bases and activated such as to create an air flow from bottom to top which laps for one half the front face of the laminar portion 2 and for the other half the rear face of that same portion 2.
It will appear how during the operation of the radiator a powerful thermal exchange is achieved and a larger delivery of air to the room.
The radiator form described hereinabove adjusts it-self thermally to varying room conditions. It may operatestatically, i.e. with the blowers deenergized, as well as, alternatively, dynamically, i.e. with the blowers energized. ;~
In turn, it is also possible to adjust the rising air stream push by adjusting the voltage fed to the blower motors.
A simple adjustment of the radiator potentiality is obtainable by simply turning on and off the blowers, Indeed, from actual tests carried out, it has been found that the radiator potentiality is more than double with the blower activ~ted than it is in a similar radiator but with the blowers turned off.
The invention is susceptible to many modifications and variations, all within the scope of this inventive concept.
For example, the fins 7,8 may extend to the top and bottom from , the plane of the axes of the sleeves 3,4, as shown in Figure 4.
In this embodiment, no diaphragm is provided for confining at the center the blower housing seats.
In a further variation, of this invention, provision is made to operate the radiator a~ a stove. To this aim, the heating fluiddelivery and return are closed by suitable shut off gate valves, while in the lower sleeve there is inserted - 5 ~
' an electric resistance 27 of the plug type which is adiustable from the outside through an apparatus 28, shown by the dot and dash lines of Figure 1. While the electrical resistance heats the fluid enclosed in the radiator, the blowers 2S,26 effect the heat exchange by convection.
Advantageously, the vertical sleeve 15 i~ lined inter-nally with a steel tube which, in combination with the one-piece structure of the radiator, provides high resistance to pressure.
Thi~ permits the utilization of the radiator even with over-heated water up to 170 Atm. pressure levels.
The production of the rising air stream may beobtained, alternatively, by housing the blowers in seats formed above the upper sleeve 3 or below the lower sleeve 4 and oper-ating them, in the former instance, as pulling or suction fans.
Advantageously, provision is made for mounting the blowers after the radiator has been installed. In order to facilitate such a mounting, each blower is, for example, pro-vided with a socket effective to engage by insertion a socket integral with the radiator ~uch that, when the blowers are seated, m~chanical support for the blower is obtained as well as its connection to the mains supply. The socket may be con-figurated as a horizontal bar attached to the radiator or to i- :
; the front or rear panels.
; The shapes and dimensions of the radiator just des-cribed allow its installation in a niche, cantilevered from a ;~ wall or even suspended.
Although the radiator is mainly intended for heating purposes, it may also be used for air conditioning. In this .
latter application it will be advisable, however, to place under the radiator a dripping pan for collecting any conden-sation.
