The group of inventions relates to a heating technique, and more particularly to a heating radiators convectors for hot water Central heating and ways of fixing aluminum pipe register in the holes of the tubular collector made of aluminum profile. The group of inventions can be used for heating of residential, public and industrial buildings and in industrial processes production of heating radiators convectors claimed design, manufactured using finned aluminum tubes.

Known sectional heating radiator for hot water Central heating, each section of which includes a vertical steel tube of rectangular cross section connected by welding with cuts such as pipes, forming after Assembly of the upper and lower manifolds. Steel elements of each section in the manufacture of heat dissipating elements by casting of aluminum alloys are used as embedded parts and serve for the passage of coolant. Next sections are going to radiator battery. Heat dissipating aluminum elements are in the form of ribs and spikes [1].

A disadvantage of the known heating radiator is the complexity of the design and technology of manufacturing and Assembly.

The well-known sectional is th heating radiator, includes a number of vertical finned tubes made of aluminium profile, located between the upper and lower reservoirs, also made of aluminium profile. Oral collectors and vertical pipes of the case are communicated with each other by tight junctions, each of which is made in the form of a nipple with a threaded section, placed in the threaded hole of the collector. At the base of each hole is made chamfer mating with the edge, which ends with the threads on the nipple. And chamfer the holes in the manifold and chamfer the inner surface of the pipe register after apresski on her nipple form between them a V-shaped annular gap in which is located a sealing gasket and pressed into the tube portion of the nipple is placed is installed in the groove. The fins of each tube is made in the form of a double-sided comb with symmetrically placed in the center of the pipe [2].

The disadvantage of the described construction of sectional heating radiator for hot water Central heating, taken as a prototype, is the complexity of manufacture and Assembly because of the large number of Assembly units and low adaptability. The use of the compounds of the radiator sealing gaskets and seals under conditions of temperature kalopanayiotis to premature aging of gaskets and sealing and unsealing a sealed connection. Hydraulic impacts associated with filling and draining of the coolant in the heating system, with commissioning due to the ageing of gaskets, seals and seal failure connections quickly put out of order a radiator that will ultimately lead to significant labor and material cost for replacement of defective radiators.

These drawbacks do not guarantee safe and reliable operation known radiators at operating pressures above 10 ATM.

The known method of securing the tubes in the tube sheet holes, including the installation of pipe in the hole in the tube with the release pipe end having a groove, outside grill, hosted by the speaker of the pipe end annular sealing element, the distribution pipe on the length of the grid openings and the flared protruding end of the pipe to education groupinga collar, clamped sealing element to the tube sheet holes and providing a tight seal [3].

In addition, in the particular case of the invention device, the upper and lower manifolds in place of mounting fittings have longitudinal flat sections, the thickness to which x is greater than the wall thickness of the round cross-section.

In another particular case, the implementation of the invention, the fins of each tube of the case made in the form of longitudinal radial fins arranged symmetrically about the axis of the pipe, and the front and back planes of the fins to form at least two adjacent plates closed air passages communicating with the atmosphere at the upper and lower headers.

In the following particular case of the invention the diameter of the cylindrical part fitting is made with tolerances, making it fit into the hole of a header with tension. On the edge of the inlet is made of lead-in chamfer, the angle which the axis of the hole is greater angle of inclination of the transition cone 0.5-2 degrees. Conical surface of the transition cone and the conical part of the nozzle have a reverse taper. Annular grooves on the outer surfaces of the cylindrical and conical parts of the fitting is made with a rectangular cross-section.

The design of the heating radiator-convector allows you to use the profiles obtained by the method of cold p is escolania of aluminumagnesium alloys, which is much stronger than cast aluminiumrelief alloys used in counterparts. In addition, the exclusion from the design of the radiator-convector seals and gaskets also increases its durability.

The pipes of the register in the holes of the collector in accordance with the claimed method allows not only to improve maintainability and to simplify the technology of manufacturing and Assembly radiator-convector, but also to increase its strength due to the monolithic structure.
