Abstract

PROBLEM TO BE SOLVED: To provide a radiator of a pipe structure, which is adaptable to all the fashion of installation with a single radiator, thereby to reduce all the cost relating to manufacture and storage of the radiator. SOLUTION: In this radiator, pipe joints are configured to at least two adjacent sides, inlet and outlet joints 7, 8 respectively on the first side are connected by the first connection pipe 9, and inlet and outlet joints 11, 12 on the second side are connected by the second connection pipe 13. When either one of the connection pipes is closed by a closing plug 14 placed in the relevant connection pipe through the adjacent joint, and the connection between a connection pipe and a joint on the second side is closed, then heated liquid flows from the inlet joint 7 on the first side into a pipe structure 1, and then through the second connection pipe into the outlet joint 8 on the first side. On the other hand, when the connection between the second pipe on the second side and the joint on the first side is closed, the heated liquid flows from the inlet joint 11 on the second side through the first connection pipe into the pipe structure, then to the outlet joint 12 on the second side.

2. Description of the Related Art In a pipe type radiator, a pipe structure is usually made of copper, a convection surface structure is made of an aluminum plate surrounding the pipe structure in a rib shape, and, for example, a steel or iron structure is corrosive to the environment. Used in locations where it is, or at least is subject to corrosion by substances or moisture. However, such radiators can of course be used elsewhere if the radiator's appearance or high price is not of concern.

Such a radiator may be provided on one side, for example on the end of a radiator whose fitting is directly joined to the pipe end of the pipe structure, or on a radiator in which the pipe structure is connected to the heating liquid system from the end. In the same case as the model, the fitting is equipped with a fixed fitting underneath the radiator provided by auxiliary piping. Therefore, two different radiator models are needed to realize two different connection methods for the same basic structure, and one of the structures presents technical problems due to the need for auxiliary piping. . In addition to technical issues, from a strategic point of view it is disadvantageous to offer several models of the same product and to store such various models simply for different installation methods.

This problem has already been solved long ago in steel panel radiators. However, the technique used for such radiators, which allows the liquid to flow freely inside the radiator, is not applicable to the aforementioned radiators realized by guided liquid circulation, in which case the heated liquid is Forced into the system from one end, circulated in the pipe system along a predetermined path and removed from the pipe system from the other end.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the above-mentioned pipe radiator to solve the above-mentioned problems. This object is achieved by a radiator according to the invention, which has pipe fittings arranged on at least two adjacent sides of the radiator and a first side input and output fitting by a first connecting pipe. Connected, the input and output fittings of the second side are connected by a second connecting pipe, any of the connecting pipes being able to be attached to said connecting pipe via the pipe fitting on the adjacent side Can be closed by a plug, which allows
When the first connecting pipe and the pipe joint on the second side are closed,
Heated liquid is introduced from the first side input fitting to the pipe structure and from there through the second connecting piece to the first side output fitting, the first side second connecting piece. And the pipe joint is closed, the heated liquid is led from the input joint on the second side through the first connecting pipe to the pipe structure,
From there, it is guided to the output joint of the second side surface.

The invention is based on an integrated valve structure between the inlet and outlet of a pipe structure, which comprises a pipe joint for connecting a radiator from two different directions. Therefore, by using the connecting pipe and the closed plug arranged in the valve structure, simply changing the position of the closed plug and plugging the unused joint, the paired pipe joint and each pair of joints It is possible to switch between the two flow paths of heated liquid between.

The advantage of the arrangement according to the invention is that a single radiator can be utilized for all modalities of the installation actually required, thereby reducing all costs associated with radiator manufacturing and storage. Is Rukoto.

The invention will be described in detail below by means of preferred embodiments with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a pipe radiator according to the present invention comprises a pipe structure 1 made of, for example, copper or a copper alloy for circulating a heating liquid, and a convection flow connected to the pipe structure 1. It comprises a surface structure 2 and a valve structure 3 also connected to the pipe structure 1 for supplying heated liquid to the pipe structure and for discharging it from the pipe structure. The convection surface structure 2 consists of convection panels 4 made of, for example, aluminum and fixed around the pipe structure. Aluminum is an advantageous material due to its light weight and high thermal conductivity.

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

As shown in FIGS. 2 to 4, the input joint 7 and the output joint 8 of the first pair of joints 5 are connected by the first connecting pipe 9, and the input of the second pair of joints 6 is connected. The joint 11 and the output joint 12 are joined by the second connecting pipe 13, so that the input joint 7 of the first pair of joints 5 and the output joint 12 of the second pair of joints 6 are in direct flow at the same time. Are connected as.

Alternatively, either of the connecting pipes 9, 13 may be closed by a closing plug 14, which is connected from the pipe fitting 8 or 11 in series with the connecting pipe into the connecting pipe 9 or 13 concerned. Can be placed at.

In FIG. 2, the first connecting pipe 9 is closed by a closing plug 14, and a pipe pair 11, 1 of the second pair 6 is connected.
2 is closed, for example by putting a valve insert 15 and a thermostat 16 in the fitting 12 and a simple plug 17 in the fitting 11, the heated liquid being the input fitting 7 of the fitting 5 of the first pair. From pipe structure 1
To the output joint 8 of the first pair of joints 5 via the second connecting pipe 13.

On the other hand, in FIG. 3, the second connecting pipe 13 is closed by the closing plug 14, the pipe fittings 7, 8 of the first pair 5 are closed by the plugs 18, 19, and the heating liquid is It is guided from the input joint 11 of the two pairs of joints 6 to the pipe structure 1 via the first connecting pipe 9. Not shown in this figure are the valve inserts and thermostats that may be located in fitting 12.

The closing plug 14 also comprises a bypass pipe 20 of substantially smaller diameter than the connecting pipes 9, 13, which bypass pipe can be opened and closed by means of a second closing plug 21, whereby the bypass pipe is closed. When the tube 20 is opened, some of the heated liquid can be directed to flow through this bypass tube 20 towards the radiator. FIG. 4 illustrates the use of such bypass circulation in the connection shown in FIG.

For example, both closing plugs 14, 21 are preferably threadedly mounted, so that the plugs are plugged into their respective tubes 9, 1 by means of, for example, a hexagon wrench.
Can be screwed into 3,20.

Furthermore, it is also possible to realize the above arrangement in the opposite direction, ie the input joint 7 can serve as an output joint and the output joint 8 can serve as an input joint, correspondingly the input. Note that fitting 11 can serve as an output fitting and output fitting 12 can serve as an input fitting. In the case shown in FIGS. 2 and 4, the joint 8 can also be plugged, in which case the joint 11 serves as an alternative to the joint 8. Correspondingly, in the case shown in FIG.
The plug 19 can be arranged in the fitting 11.

The above description of the present invention is presented only to illustrate the basic concepts that are inventive. Therefore, those skilled in the art can implement the details in various ways without departing from the scope of the invention as defined in the appended claims.
