Tubular radiator

Background of the Invention

The invention relates to a tubular radiator comprising a tubular structure for circulating heating fluid, a convection surface structure 5 associated with the tubular structure and tubular connections associated with the tubular structure for inlet and outlet heating fluid.

Such tubular radiators, in which the tubular structure is generally copper and the aluminum surface of the convection surface structure, which is surrounded by a sheet of aluminum, are used e.g. in applications where steel or iron-10 radiators would be corroded or exposed to corrosion due to corrosive substances or moisture in the environment. Of course, there is nothing to stop you from using these as long as the appearance or higher price does not cause problems.

These radiators have fixed pipe connections on one side, for example, on the end side directly connected to the ends of the tubing pipes, or perhaps on the underside, possibly using special additional piping, provided the tubing is the same design as the end side. That is, two different radiator models are required to implement two different connection methods in the same basic structure, whereby the other construction also causes technical problems due to the additional piping. In addition to technical problems, keeping multiple models in the product program and in stock simply because of different installation methods is logistically disadvantageous.

This problem has long been solved in steel plate-shaped radiators, but · * · · The technology used in these radiators that allow the flow of 25 fluids cannot be used: is used in these forced-controlled radiators, where is forced into the pipeline at one end, circulated through the pipeline and removed at the other end.

: 30 Summary of the Invention

It is thus an object of the invention to provide a tubular radiator as described above in order to solve the problems described above. This object is achieved by a radiator according to the invention, characterized in that the pipe connections are arranged on at least two adjacent sides of the radiator, that there is a first communication channel between the first page inlet and outlet 113893 2 and a second page between the second page inlet and outlet. , and alternatively, either interconnecting channel can be closed by a closure plug which may be mounted on the respective interconnecting channel through a pipe connection on an adjacent side, the heating fluid being directed from the first to the inlet connection, and when the second connecting conduit and additionally the first side pipe connections are closed, the heating fluid is directed from the second side inlet 10 n connecting duct to the pipe structure and thence to the other side outlet connection.

The invention is based on a valve structure integrated between the inlet and outlet of the tubular structure with pipe connection connections for two-way radiator connection, where plugged connections.

The advantage of the solution according to the invention is that a single radiator 20 can handle all practically existing installation methods, thus minimizing all costs associated with the production and storage of the radiator;

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. The convection surface structure 2 consists of convection plates 4, for example aluminum, fixed around the tubular structure 1. Aluminum is a preferred material because of its good thermal conductivity and light weight.

The valve structure comprises two pairs of pipe connections 5 and 6, one on the vertical side of the radiator and the other on the horizontal side of the radiator.

2 to 4, there is a second connecting duct 13 between the inlet 7 and the outlet 8 of the first one pair 5 and the second one of the inlet 11 of the second pair 6, the outlet 12 of the first one pair 5 and the outlet 12 of the second one pair 10. while in direct flow with each other.

Alternatively, either of the connecting ducts 9 or 13 can be closed by a closure plug 14 which can be mounted on the respective connecting duct 9 or 13 via the respective pipe connection 8 or 11.

2, wherein the first connecting duct 9 is closed by a closing plug 14 and the pipe connections 11 and 12 of the second single pair 6 are closed for example by j '; with the valve insert 15 installed in the connector 12 and the plug 17 in the thermostat 16 and 25 only by the plug 17, the heating fluid is directed from the inlet connection 7 of the first connector 5 to the tubular structure 1 and thence through the second connection channel 13 to the outlet 8 of the first pair.

3, the second connecting duct 13 is closed by a stopper 14 and the pipe connections 7 and 8 of the first single pair 5 are closed by a flange 18 and 19, the heating fluid is directed from the second single pair 6 through the first connecting duct 9 to the pipe structure 1 and thence to a second pair 6 to the outlet 12. · · *. valve insert and thermostat not shown.

Further, the closure housing 14 is provided with a bypass conduit 20, 35 substantially smaller in diameter than the connecting conduits 9 and 13, which can be opened and closed by a second closure plug 21, wherein the bypass conduit 113893 4 is open to control a radiator. Figure 4 illustrates the use of such a bypass capability in connection with the circuit of Figure 2.

Most preferably, both closure plugs 14 and 21 are threaded, whereby they can be screwed into the respective passageways 9, 13 and 20, for example by means of a hex key.

In addition, it should be noted that nothing prevents the flows described above being reversed, i.e., the inlet 7 may serve as the outlet and the outlet 8 as the inlet and the si-10 weather inlet 11 may serve as the outlet and the outlet 12 as the inlet. In the cases of Figures 2 and 4, the plug 8 may also be plugged, whereby the plug 11 will perform 8 tasks together. Similarly, in the case of Fig. 3, the stopper 19 may be moved to the connector 11.

The foregoing description of the invention is intended only to illustrate the basic idea of the invention. Thus, a person skilled in the art can implement its details in many ways without departing from the scope of the appended claims.
