Definitions

• the multi-row radiator with a controlled flow of heating medium Field of the Invention
• This invention relates to a multi-row radiator with a controlled flow of heating medium, in particular the multi-row heating plate unit with an inlet port and an outlet port of the heating medium, with the first passing-through heating plate facing the heated room / space and with at least one heating plate situated behind said first plate intended for reducing flow of the heating medium for cutting or controlling the heating output, and which comprises an optional function of reversal fitting etc.
• radiators especially the heating plate units are manufactured as single- or multi-row units, inside of which a space for the flow of heating medium, which is usually water, is provided.
• the heating medium is supplied to the individual heatmg plates from the inlet port through the supply fittings and flows always symmetrically in all radiator heating plates, i.e. the same amount is directed in all heating plates, or asymmetrically, usually preferably in the first of the heating plates facing a heated room, using a system for flow distribution such as different screens, but there is always no possibility to control the flow ratio distributed among individual heating plates, or to shut off the relevant inlet, etc.
• heating plates or those of other similar heating units are always hydraulically interconnected, so that it is impossible to control the flow of the heating medium in a particular heating plate without having to influence the flow of the heating medium through the second or subsequent heating plates of the known mutually hydraulically interconnected multi-row heating radiators.
• the front radiator plate will be warmer thus presenting more pleasant touch feeling than existing systems.
• this advantageous effect is even intensified by the fact that the front of the heating plate features a higher radiation ratio.
• at least one connecting tube or possibly a supply fitting are arranged in the system, and said supply fitting is preferably situated at the lower corner area of the radiator front heating plate, from which then the partly cooled-down heating medium flows into the lower part of the second heating plate situated behind it or possibly into the subsequent plate of the multi-row heating radiator.
• the heating medium of this second heating plate is supplied at first upwards to the upper longitudinal edge of the second or possibly subsequent heating plate, wherein the liquid is again directed through the upper distribution channel provided to be consequently supplied, by means of perpendicularly attached flow channels, to its second lower corner area with a connected outlet port.
• the heating medium transfers the greater part of its heat capacity to said frontal heating plate, while entering, already partly cooled, the second or subsequent heating plates, ensuring in such a way a reduced heating output.
• the obvious drawback of this arrangement is that the regulation of the reduced heating output of the second or subsequent heating radiator plates of the multi-row heating unit can not be controlled.
• the task of the present invention is to improve the flow control process of the heating medium through the multi-row radiator, especially through the multi-row heating plate radiator that is equipped with inlet and outlet ports of the heating medium, and usually with the first passing-through heating plate facing a heated room / space and with at least one subsequent heating plate situated in a row behind it to obtain the intended medium flow reduction for cutting down or controlling the heating output, and said heating plates are mutually connected on the corners of their upper distributing channels by means of inflow fittings and / or by a connecting set with an inflow fitting for the inlet port of the heating medium and at lower distributing channels with an outflow fitting for the outlet port, whereby the specified task is achieved by the present invention, characterized in that any of the inflow or outflow fittings are designed as a divider with the internal separation screen intended for the separation of the heating medium flows either into or out of the individual heating plates, and which is to that end provided with a central separation screen that forms mutually separated channels in the auxiliary body of the selective merger / splitter of the streams, wherein
• the radial recess in the cylindrical obturator is adapted to form a half-round groove or an angular profile, wherein a circular segment in the relevant part of the cylindrical obturator, whose chord or the arc length of this circular section overlaps the outermost distance of external contours of the mutual separated channels in the auxiliary body of the merger / splitter.
• the invention offers advantageously a variety of possible combinations, for example, that a control valve is arranged in series with the inlet port and the inflow fitting for distribution of the heating medium in all heating plates, whereby the merger / splitter and the valve can be integrated in a single device.

• the flow control of the heating medium through a multi-row radiator 1, in particular through a multi-row heating plate unit with an inlet port 2 and the outlet port 3 of the heating medium, said radiator having the first passing-through heating plate 4 facing a heated room / space and at least one heating plate 5 situated behind said plate to obtain the intended medium flow reduction for cutting down its heating output, is described in using the drawing of a common basic arrangement of the multi-row radiator I that consists for example of at least two rows of known heating plates 4J5 arranged one behind the other, which are equipped with the internal upper distributing channels 6 and the lower collecting channels 7 interconnected by a system of vertical channels (not depicted here in more detail).
• the heating plates 4,5 of the heating radiator i are mutually rigidly connected on the corners at their upper distributing channels 6 and the lower collecting channels 7 by means of the spacer bushings 8, which, however, are blind unlike the usual and well-known fittings, as highlighted hatched in the figure, except for the inflow fitting 9 at the inlet port 2 of the heating medium, wherein the necessary outflow fitting JjO for the common outlet port 3 of the cooled-down heating medium is designed as a divider 16 for the internal separation screen J_l (hatched highlighted) intended for the separation of individual outflows of the heating medium returning from the individual heating plates 4,5 or their groups into the separate channels 12,13 of an auxiliary body of a selective merger 14 of said individual outflows.
• the body of the selective merger 14 is then connected either directly with its drain orifice 26 or it is connected with the common outlet port 3 through the shut-off fitting 15.
• Blindings of said spacer bushings 8 are either done already by the manufacturer or they are additionally provided with various flexible screens 19, etc., and at least one of them is equipped with a vent valve (not shown here).
• the separation screen 1_1 of the divider 16 is assigned with its interface 17 to the central crosspiece 18, which forms the separated channels 12,13.
• a threaded bushing 21 is attached across its longitudinal axis and parallel to the central crosspiece 1_8 for a group of a valve shaft 22, and said threaded bushing 21 protrudes sealed into the auxiliary body of the selective merger / splitter 14 through the cylindrical obturator 24 which is provided with a radial recess 23, for which, in combination with the frontal edge of the central crosspiece 18, a cylindrical seat 25 with the single main inlet / outlet orifice 26 is formed in the body of the selective merger / splitter 14.
• the central crosspiece 18 can be naturally replaced by a core made of heat-resistant material (not shown here) with the appropriately formed mutually separated channels 12,13 in using an appropriate manufacturing process.
• the group of the valve shaft 22 includes a coaxial sleeve 27 to guide and to seal the valve stem 28 of the valve shaft 22, wherein the free end of the valve stem 28 is provided with a carrying shoulder 29 for the hand knob 30 and / or an actuator of a servomotor (not shown here), controlled by the temperature sensor and connected in the equithermic system etc.
• the depicted hand knob 30 (Fig.
• valve stem 28 at the end of the valve stem 28 is provided with orientation marking (not shown here) for visual perception of the positioning of the valve shaft 22, whose position ensures the individual control of the heating medium inflow into the radiator plates 4 ⁇ 5 of the multi-row radiator 1, including the complete flow interruption thereof through the multi-row radiator I, and which can be also used as an replacement for the shut-off fitting 15, or for adjusting a fully free outflow of the heating medium from the heating plates 4,5 of the multi-row radiator 1 into the outlet port 3 of the cooled-down heating medium.
• a half-round cut or an angular profile represents the radial recess 23 in the cylindrical obturator 24 wherein the half-round cut forms a circular segment shown in particular in Figures 6-9 whose chord length S or the arc length corresponds to the outermost contours of the mutual separated channels 12, 13 ensuring in this way that the cylindrical obturator 24 works in its seat 25 as an throttling, closing and opening element, as shown in particular in the attached Figures 6-9.
• the suggested arrangement of the radiator i shows, that the inflow and outflow chain of the heating medium can be mutually arranged in a reversed position, namely, that the heating medium is selectively distributed by the selective merger H with splitting function already in the inflow fitting 9 that is equipped for this purpose with the separation screen ⁇ , whereas the outflow fitting 10 that interconnects the individual outflows from the heating plates 4,5 is free for outflow through the shut-off fitting 15 to the outlet port 3.
• the selective merger 14, now acting as a selective splitter can be preceded by a usual control valve 20, or the selective merger / splitter 14 and the control valve 20 can be connected together to form a single device (not shown here).
• the groups formed by every other heating plate 5 are mechanically and hydraulically connected at the corners of their upper distributing channels 6 and the lower collecting channels 7 by using for example spacer tubes 16 (not shown here), whereby some of them are blind, according to the above outline of the basic layout of the multi-row radiator J., etc.
• the parameters of the body of the selective merger / splitter 14 can be preset by the manufacturer to be manually or motor controlled or mounted only after installation of the multi-row radiator I in the heating system in order to achieve the desired change of hydraulic resistance of the individual channels J_2,l_3 of the selective merger / splitter J , hence of the hydraulic resistance of the heating plates 4 ⁇ 5 or their groups for the heating medium that enters the system of the multiple row radiator I through the inflow fitting 9 at the inlet port 2, usually equipped with a shut-off or control valve 20.
• the selective merger / splitter 14 Due to the use of optional and sophisticated design of the selective merger / splitter 14 is the presented way of controlling the flow of the heating medium through a multi-row radiator 1, in particular through the multi-row heating plate unit effective even in that the ratio of the individual outflows of the returning heating medium from the individual heating plates 4 ⁇ 5 can be varied largely in the range of 1 : 1 or 1 : 0 or vice versa by selective merging.
• the selective merging too, again according to the chosen design of the selective merger 14, can be completely interrupted so that the outflows of the heating medium returning from the all heating plates 4,5 would be completely shut off, thereby meeting the current requirement to have the radiators I fitted with the bottom shut-off fitting 15 (Fig. 2).
• the said selective merging of the outflows of the heating medium returning from the individual heating plates 4,5 is set to predetermined ratio already by manufacturer or alternatively the selective outflow merging of the heating medium returning from the individual heating plates 4,5 can be adjusted or individually controlled with variable ratio required by the user or automatically depending on the ambient temperature and other conditions, such as use of a thermostatic head, an actuator with corresponding sensor, etc.
• the selective merging of the outflows of the returning heating medium hence the design of the selective merger / splitter 14, does not preclude that the multi-row radiator I fitted with it would be adapted for the classical upper connection to the heating system, or that it is equipped with so-called bottom connection with the bottom central connection using the known valve group (not shown here) etc.
