FR2564185A1 - Radiator for central heating system - Google Patents

Abstract

The radiator consists of a number of heat radiation elements (1), each consisting of a heat-conducting and heat-resistant material. Each element has a socket, with slots (3,4) to accommodate a corresponding connection section, to act as bayonett connection between two elements. This forms a panel-shaped radiator. Each connection section has locking shoulders, which slide along the slots and removably engage with the socket, by being turned in an angled relative direction.

Description

The present invention relates to a radiator for installa
central heating.

Conventional radiators for heating installation
central are generally heavy to handle because they are
made of metal such as cast iron or steel. Each
radiator element has a weight of approximately 7 kg. and
as the entire radiator usually has ten
elements, the total weight of the radiator is around 70 kg. For
this reason two people are usually needed
to ensure the installation of the radiator. In addition to
support consoles must be anchored and sealed in the
wall, this to support each radiator and this requires
the assistance of a mason to ensure the operation of sealing the consoles in the wall and we end up in
consequence of high labor costs and
long implantation times.

In addition, the radiator elements are connected to each other.
others by a connector screwed into each of the elements. The
connectors are usually priced at
high workmanship because they must have on each side
threads on the right and left respectively and more
corresponding threads must be placed in the
radiator element receiving elements or ports.

Another drawback encountered in the use of
metal radiators comes from what the inner wall
water circulation chambers present a state of
rough surface, which decreases and handicaps the efficiency and
regularity of heat exchange and loss
calories on the entire radiator.

The present invention relates to a radiator for a central heating installation which substantially reduces or eliminates the drawbacks which are mentioned above with regard to conventional radiators.

To this end, the present invention relates to a radiator comprising a plurality of heating elements made from heat-conductive and heat-resistant plastic, each element comprising mouthpieces and the elements being interconnected by a plurality of fittings hollow able to penetrate into said mouths by ensuring the junction of a heating element to the other.

An embodiment of the present invention will be described below by way of nonlimiting examples with reference to the accompanying drawings.

FIG. 1 shows a heating element in section along the line I-I of FIG. 2.

FIG. 2 is a side elevation view of one end of the heating elements of FIG. 1.

Figure 3 shows a perspective view of the mouth of the heating element.

Figures 4,5 and 6 respectively show a longitudinal sectional view, a transverse sectional view and a perspective view of a connector capable of ensuring the junction of two heating elements.

Figure 7 is a partial sectional view showing the junction of two assembled heating elements.

Figures 8 and 9 respectively show a longitudinal sectional view of a valve adapted to fit on the mouth of a heating element.

Figures 10 and 11 are side and front elevational views of a radiator obtained by the assembly of heating elements according to the invention.

Referring to all of the figures, the heating element 1 shown is made from plastic material which conducts heat and which is capable of withstanding the temperature of the heating fluid, for example the heating water which circulates in the system. central heating.

The heating element 1 has a mouth 2 at its ends. Each mouthpiece 2 has an opening provided with two diametrically opposite notches 3 and 3 '. And an annular seat 4 is provided to receive an O-ring.

The interior of the heating element 1 comprises longitudinal chambers capable of allowing the circulation of the heating water, the chambers 5 being in communication with one another and with the mouths 2.

Outside the radiator are provided passages 6 interposed between the chambers 5 to allow the circulation of the ambient air and its heating by adding calories from the heating element.

A connector 7 comprising seals has an axial passage or conduit 8 and allows connection and communication between a pair of heating elements 1. The connector 7 has annular grooves 9 and 9 'provided to receive an O-ring respectively 10.10 '; the central part of the connector 11 is provided with a hexagonal outer periphery. At each end the connector 7 has a pair of ears 12 and 12 'which are diametrically opposite and which are dimensioned so as to allow their insertion inside the notches 3 and 3' of the mouth 2.

Under these conditions, the connector can be mounted and secured to a heating element by an assembly of the bayonet type "and allow the connection of two neighboring elements. In fact once the ears 12, 12 ′ have been engaged in the notches 3 and 3 ', the connector 7 can be rotated along its axis and by an angle of about 900 using a key engaged on the central core 11 and under these conditions the ears 12 and 12' engage against the shoulder inner ring 13 of each mouthpiece (see FIGS. 1 and 7). Using an appropriate quantity of fittings 7, it is possible to assemble several heating elements and obtain a heating panel 14 as seen in FIGS. 10 and 11.

FIGS. 8 and 9 show a shutter 15 which makes it possible to close a mouth 2 ′ at the end of a radiator 14.

The shutter 15 has the dimensions and the shape of a half-connector 7 and therefore does not require more detailed descriptions.

In FIGS. 10 and 11 we see at 17 the brackets fixed on a wall to support the radiator 14. Given the very reduced weight of the plastic radiator produced in accordance with the invention, the brackets can be easily and quickly put in place without sealing using simple dowels 18.

It can be seen that according to the invention it is possible to obtain very light weight radiators which are easy to handle and to assemble as well as to install. The fittings 7 with their balonette assembly can be easily disassembled if necessary.

Claims (5)

1 - Radiator for central heating installation of the type comprising a plurality of heating elements, characterized in that each heating element (1) is made of plastic material resistant to heat and good conductor of heat, each element comprising mouthpieces ( 2) and the elements being connected by fittings (7) provided to allow their engagement and their removable attachment to the mouths (2) of the elements by ensuring the connection of two elements to each other. 2 - Radiator according to claim 1, further characterized in that each mouth is provided with at least one longitudinal notch (3.3 ') and each connector has at its end a number of ears (12.12') projecting towards the outside equal to the number of notches provided on the mouthpieces, each fitting thus being able to be inserted into two neighboring heating elements and secured by angular rotation relative to these elements. 3 - Radiator according to claim 2, characterized in that each mouth has two notches (3,3 ') diametrically opposite and each connector has at its ends two ears (12,12') projecting radially and diametrically opposite. 4 - Radiator according to one of claims 1,2 or 3 above, characterized in that the connector (7) comprises an annular seat (10,10 ') to receive a seal. 5 - Radiator according to one of claims 1,2,3 or 4 above, further characterized in that it comprises a shutter (15) provided with a seal (10,10 ') and having the configuration of a half-fitting.
