Description

, 119462

The present invention relates to a method for controlling the flow of a radiator, such as a drying radiator, and a drying radiator thus obtained, and in particular to a circulating hot water-heating radiator consisting essentially of tubes and often referred to as a towel radiator.

The generic type of towel radiator has long been known as various versions. The general principle of these is that there are usually a plurality of transverse pipe sections connecting between said two vertical pipes. It is intended that the hot water supplied from the lower end of the second vertical pipe passes upwardly and along said transverse pipes into the second vertical pipe section and at its end the water returns to circulation.

Said solution works relatively well when the configuration of the radiator is mentioned above. However, there are numerous situations in which it is expedient to arrange the water circulation of the radiator so that the incoming water as well as the outgoing water passes through the pipe connections at the top of the radiator. If the conventional radiator: ***: 20 is arranged in this manner, flow will only occur through the upper cross-sections while the lower cross-sections are cold. It is clear that the intended purpose of the battery "*" will not be fulfilled.

Numerous solutions are also known which attempt to influence the internal circulation of the radiator by providing an internal tube inside the normal tubes of the radiator, which allows the flow to be directed to a particular part of the battery. Such examples are given in EP · 928939 and 1568961 and in French Patent Publication 2842286. Thus, the inner tubes are known, but the above-mentioned publications are missing. a basic arrangement typical of the solution of the present invention is that the water flow of the radiator is directed to the radiator from above. Problems occur: * ·]: Specifically when the natural temperature difference of the water no longer assists the water circulation inside the radiator.

2 119462 It is an object of the present invention to provide a method and a radiator solution which do not suffer from the above drawbacks. This is achieved by a method and a radiator, the characteristic features of which are given in the appended claims.

The invention will now be described in more detail with reference to the accompanying patent drawing, which shows a side view and a partially transparent radiator of the invention. The method becomes apparent from the description of the radiator.

As stated, the purpose of the radiator according to the invention is to solve a problem which is specifically related to a radiator having connections for incoming and outgoing circulating water at the top of the radiator. Under normal circumstances, it is impossible to obtain such a heater throughout the radiator. In this case, the circulation of water is practically limited to the top of the radiator.

The radiator 1 according to the invention is conventionally made up of two substantially vertical pipe sections 2 and 3, one at the upper end of which the heating medium is introduced and the other at the upper end of which the spiral medium leaves the radiator. Flows in the figure are illustrated by arrows.

* · _: *: 20 • ·:, ** · {The figure shows that the radiator includes conventional connectors and controls 4, 5 for connecting pipes to the radiator and adjusting the flow as needed. Also, * # · bleed screws 6 are connected to the ice system in a sensible manner so that substantially all air is removed from the system to ensure flow.

Reference numeral 7 denotes transverse flow channels, in particular pipes, whereby the flow is to pass from the inlet pipe 2 through the transverse pipes 7 to the outlet pipe 3.

Since the flow under normal conditions is through only a few upper transverse tubes, it has been realized according to the invention that the flow must be forced in an appropriate way along the desired path. According to the invention, this is provided by an additional pipe 8 which is placed inside the outlet pipe 3.

• · • · · · ··· · ·

The tube 8 extends almost to the dimension of the tube 3 with its open mouth close to the lower end of the tube 3. At its upper end, pipe 8 is adjacent to the pipe 3 or fitting 5 adjacent to the location 9 denoted by reference numeral 9, so that flow can only take place mainly through pipe 8, but not from the outside. Obviously, since the starting point of all flow is at the lower end of the tube 8, the flow from the transverse tubes 7 must be directed towards said lower end. This causes the flow from the transverse pipes 7 5 to enter the pipe 3 outside of the inner pipe 8, from where it extends, in order to reach forward, downwardly towards the lower end of the pipe 8, from where it can pass into the pipe 8

The solution operating in accordance with the invention is one in which all the flow is forced into the pipe 8 and from there to the circulation. However, it is possible that part of the flow is directed into circulation within the pipe 3, but outside the pipe 8 by making suitable flow channels for the area 9. Another possibility for such flow distribution as shown is to use an inner tube 8 having the desired holes in its jacket to allow controlled flow through them as well.

15

The dimensioning of the tubes 3 and 8 is not very critical, however, it is clear that the dimensioning of the tube 8 must be such that its size is not unnecessarily impeded.

The radiator according to the invention is particularly well suited for use in bathrooms in which the towels 20 are easy to hang on the transverse pipes 7 for drying. The radiator made in accordance with the invention ensures that each transverse tube can * "*: function for its intended purpose, that is, to provide heat of drying, the towel was hung on the upper or lower transverse tube.

The radiator according to the invention enables new types of pipe drawings in that it was previously impossible to use the piping from above for the purpose of the invention due to the failure of the radiator. Thus, solutions in which the pipes * ·· ** ·· * are placed near the ceiling of the room above a possibly suspended ceiling '[·'] have been made possible by the present invention.

···:: 30

The radiator according to the invention is made of a suitable material which, for aesthetic reasons, is often a chromed copper pipe in such objects.

Other materials are not excluded in any way.

Although the foregoing refers only to heating radiators, it is clear that the basic idea of the invention is also applicable to cooling radiators. In this case, it may be the case that the flow of medium is led to and away from the bottom of the radiator duct system. However, it is essential that the flow is forced into the desired pattern 5 by the arrangement of the invention.

It is also clear that while the invention solves in particular the problem associated with the use of a radiator of the type shown in the case of supplying fluid from above, the radiator according to the invention works equally well in the conventional position.

It is possible to modify the invention within the scope defined by the inventive basic idea and the appended claims.
