Sectional heating radiator
(57) Abstract:Usage: in the heating technique. The inventive sectional radiator contains a number of extruded finned tubes made of aluminium profile, each of which by means of a sealed connection communicates with the upper and lower manifolds, made of presovannogo aluminum profile. Tight connection contains the nipple 4 having on one side a threaded section 5, which ends with a chamfer 6, and on the other side of the nipple 4 is made section 7 with a tolerance corresponding to the press fit, on the surface in which the grooves 8 posted by seals 9. The screw holes collectors end at the base of the chamfer 10, which together with the chamfer 11, performed on the inner surface of the pipe, forming a V-shaped annular gap 12, the locking strip 13. Aluminum profile is a double-sided comb with symmetrically placed in the center of the pipe. The invention provides reliability by improving the tightness and intensification of heat transfer. 1 C. p. F.-ly, 3 ill. The invention relates to heating systems, in particular to a device for heating the walls in systemplan, containing a number of finned vertical columns streamlined, connected by horizontal channels. This ribbed vertical columns made with a trapezoidal cross-section, the parameters of which are regulated, and to focus turbulence in the flow of coolant from the front surface of the radiator, horizontal interconnect channels is shifted to the latter 
In this technical solution, the presence of ribs on the vertical columns and the horizontal offset of the channels to the frontal plane of the heat sink to increase heat transfer, however, the square edges of the vertical columns is too small to ensure good heat transfer. In addition, the feed-through channels received by the casting of columns, have a rough textured surface, contributing to the blockage of the channels and, consequently, reduction of operational reliability.The closest to their design characteristics and the achieved result is heating radiator, containing a number of tubular elements made of extruded aluminum profile with fin, while the cavity of each tubular element communicates with the cavities of the upper and lower collect the gap, through which the heated air enters the chamber formed by two adjacent finned pipes, from which it exits through the louvered sections in the rear edges 
A significant drawback of this radiator is the lack of sealing gaskets, as the insertion of the nipple and in the reservoir and tubular elements even in the presence of the fixing tubular elements with collectors cannot ensure reliable operation. Another significant disadvantage is that the fins of the tubular element to form two U-shaped cavity and the volume put air into them difficult to heat the thin-walled outer edges, which are also made unreliable from the point of view of strength.The technical result of the invention is to improve operational reliability by ensuring integrity and intensification of heat transfer.The technical result is achieved in that the sectional heating radiator contains a number of longitudinal finned tubes made of aluminium profile, located between the upper and lower reservoirs, also made of aluminium profile and the cavity of which is communicated through the seal technics and the upper and lower reservoirs. 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, after apresski on her nipple, forming between them a V-shaped annular gap, which has a sealing gasket and pressed into the tube portion of the nipple is placed is installed in the groove. In addition, the finned tubes made in the form of bilateral comb with symmetrically placed in the center of the pipe.Comparative analysis of the prototype allows us to conclude that the invention is new, because it is not known from the prior art.The presence of the proposed airtight connection nipple supplied with one hand threaded section, installed in holes collectors, as well as placement of a sealing gasket in a V-shaped annular gap formed by the chamfer thread mating chamfered screw holes of the collector, and chamfer the holes of the pipe. In addition, the installation on the other side of the nipple seals placed in the grooves on pressed into the tube side of the nipple, prevents potential leak sources in editorialize fixes the seal, and accommodation in the grooves 2-3 seals on the pressed portion of the nipple ensures the tightness of the connection elements of the radiator, and therefore the operational reliability.Use as a heating element, finned tubes, made in the form of bilateral comb with symmetrically placed in the center of the pipe, in comparison with the prototype increases the heat transfer of the heat sink due to the increase of heat transfer surfaces that divide the volume of air enclosed between outer walls, eight cavities, through which the air is heated much faster.Due to the action of essential features is achieved technical result of the invention, namely, increase operational reliability and heat transfer by increasing the heat transfer surfaces.In Fig.1 shows a General sectional view of the radiator of Fig.2 section a-a in Fig.1; Fig.3 a cross-section of the finned tube.Sectional heating radiator contains a number of extruded longitudinal finned tubes 1 of aluminum alloy, each of which by means of a sealed connection communicates with the upper 2 and lower 3-manifolds, also vypolnenno one hand threaded section 5, which ends with a chamfer 6, and on the other side of the nipple 4 with a tolerance corresponding to the press fit, made section 7, provided is placed in the grooves 8 seal 9. The screw holes collectors end at the base of the chamfer 10, and the chamfer 11 is made on the inner surface of the pipe 1 and formed with a chamfer 10 of the V-shaped annular gap 12, which is fixed with a sealing gasket 13.Aluminum profile used as a heating pipe is a double-sided comb with symmetrically placed in the center of the pipe 14 (Fig.3).The Assembly sectional heating radiator is carried out in the following sequence.In the threaded holes of the upper 2 and lower 3 collectors set (retrieve) a threaded section 5 of the valve 4 so that the facet 6 of the nipple 4 and the chamfer 10 threaded hole collector 2 or 3 are integrated in a single plane, and then produce a press-on finned tubes 1 to section 7 of the nipple, tentatively placing a sealing strip 13 on the bevel 11 of the inner cavity of the pipe and seal 9 in the grooves 8. After pulling the pipe 1 at the nipple 4 is a sealing gasket 13 is clamped in the V-shaped annular sasboy.When working sectional heating radiator heat from the coolant supplied through the inlet manifold 2 or 3 to the pipe 1, is transferred from the walls of the pipe outer wall 15 and the partition walls 16, which are an additional source of radiation, the latter dividing the volume enclosed between outer walls 15, contribute to a more intensive heat transfer.The radiator design is reliable in operation and provides for efficient heat transfer. 1.
