Description

RADIATOR WITH MEMBRANE EXPANSION TUBE
Fitld of the Invention
The present invention relates Io a membrane expansion tube, which provides pressure balance, arranged on the radiator upon canceling the expansion vessel accommodated in the central unit of the heating system.
Background of the Invention
In current applications, the water used lor heat conduction in heating systems circulates in a closed system. In order to avoid the harmful effects of the heating and expansion of the water on the system, an expansion vessel is incorporated to the central unit of the heating system. Expansion tanks can be directly integrated to the product in devices such as boilers and room heaters.
Thc French patent application No. EP0080428, one of the state of the art applications, discloses a system which has air therein and where a chamber within the radiator is squeezed by the expansion of the water in the radiator. The said radiator has a totally closed expansion chamber. The chamber has a flexible nature. Upon expansion of the heat transfer liquid, the chamber, such that the pressure therein will be equal to the atmosphere pressure, collapses Io provide the volume necessary for the heat transfer liquid which expands in the radiator and protects the radiator from harmful effects that might result from expansion.
The European patent application No. FR2624588, another state of the art application, discloses a closed chamber with elastic walls immersed in the heat transfer liquid and containing air or another gas therein. Upon expansion of the heat transfer liquid, the gas within the chamber is compressed and vacates the volume necessary for the heat transfer liquid which expands in the radiator, and it protects the radiator from harmful effects that might result from expansion. Radiators that can be produced with the above mentioned chambers accommodate heat transfer liquid and comprise large chambers. Nowadays, as it is more efficient, panel radiators are not suitable for use of these kinds of chambers.
Summary of the Invention
The objective of the present invention is to realize a membrane expansion tube, which can be used in radiators by being arranged on a panel radiator that is a heating system unit, and which can operate efficiently.
Another objective of the invention is that it provides downsizing of the boiler and reduction in costs.
Detailed Description of the Invention
The radiator realized to fulfill the objective of the present invention is illustrated in the accompanying figures wherein,
Figure 1 is the side perspective view of the radiator.
Figure 2 is the front view of an expansion tube to be used with a radiator when connected to a radiator.
The components in the figures are numbered individually where the numbers refer to the following:
1. Radiator
2. Membrane Expansion Tube
3. Gas Pumping End
4. Liquid chamber
5. Membrane 6. Gas chamber
7. Connection end
The inventive radiator (1) comprises
- at least one membrane expansion tube (2) that performs the function of the expansion vessel,
- at least one gas pumping end (3) which is located at the lowest end of the membrane expansion tube (2) and pumps gas up to a predetermined pressure value,
- at least one liquid chamber (4) which forms one of the halves of the membrane expansion tube (2) and contains liquid therein,
- a membrane (5) which adjusts the system pressure with its elastic structure,
- at least one gas chamber (6) which forms one of the sections within the membrane expansion tube (2) and contains gas therein and
- at least one connection end (7) which enables the membrane expansion tube (2) to be coupled with the radiator (1) panel.
The panel radiator (1) of the invention is a 22 type panel radiator. The membrane expansion tube (2) is connected to the panel radiator (1) via the connection end (7). The gas pumping end (3) located at the lower part of the membrane expansion tube (2) provides gas input output through the membrane (5) until a certain predetermined pressure.
In one embodiment of the invention, the membrane expansion tube (2) is comprised of at least two sections. One of these sections is the liquid chamber (4) accommodating liquid therein, and the other is a gas chamber (6) containing gas. These two chambers are separated from each other via a membrane (5).
The membrane expansion tube (2) connected to the panel from the connection end (7) adjusts the system pressure during pressure drops by means of the stretching movements of the flexible membrane (5) towards the gas or liquid chamber, taking as reference the gas pressure in the gas chamber (6).
With the present invention, the expansion vessels provided in boilers are cancelled and the membrane expansion tube (2) arranged on the panel radiator (1) provides pressure balance. Mounting a membrane expansion tube (2) onto a radiator instead of a boiler, has caused both downsizing of the boiler and reduction in the production costs.

Claims

1. A radiator (1) comprising at least one gas chamber (6), which forms one of the two half sections, accommodating gas therein; a liquid chamber (4) containing liquid therein; at least one connection end (7) which enables connection to the panel, characterized with at least one membrane expansion tube (2) that performs the function of the expansion vessel.
2. A radiator (1) according to Claim 1, comprising at least one gas pumping end (3) for adjusting gas pressure which is located at the lowest end of the membrane expansion tube (2) and pumps gas up to a predetermined amount of gas.
3. A radiator (1) according to the preceding claims, characterized by a membrane (5) which is located within the membrane expansion tube (2) connected to the panel from the connection end (7) and which adjusts the system pressure during pressure drops by stretching movements towards the gas or liquid chamber, taking as reference the gas pressure in the gas chamber (6).
