Definitions

• 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 5 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, while said heating plates are mutually connected on the corner areas at their upper distributing channels by means of inflow fittings and/or a connecting set with the inflow fitting for the 10 inlet port of the heating medium and connected by the outflow fitting for the outlet port at lower distributing channels.
• 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 heating
• the heating medium is supplied to the individual heating plates from the inlet port through the supply outlets and flows always symmetrically in each of their 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 flow
• heating plates or those of other similar radiators are always hydraulically interconnected, so that it is impossible to control the flow of 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
• At least one connecting tube or possibly a supply outlet are arranged in the system, and said supply outlet is preferably situated at the lower corner area of the radiator heating front plate, from which then the cooled-down heating medium flows into the lower part of the second heating plate situated behind it or possibly into subsequent plate of the multi-row heating radiator.
• the heating medium 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 and then by means of perpendicularly attached flow channels it is supplied 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 partially cooled, the second or subsequent heating plates, ensuring, in such a way, a reduced output.
• a disadvantage of such a solution is the application of the overflow connection or overflow coupling, which significantly complicates and increases the production cost of multi-row heating radiators of such a design, and moreover, it causes problems with radiator cleaning for the end-user, and therefore the mentioned solutions did not prove enough in practice.

• the interfaces of the inflow or outflow fittings are formed by a filling core of their central parts as an integral part of their casing. According to the invention, it appears advantageous that with regard to the current development and properties of plastic materials the interfaces of the inflow or outflow fittings are carried out by introducing an injection insert made of composite material in their central part, including the created curved and mutually separated channels and with a passing-through hole for the throttling member and / or control element.
