(57) Abstract:The invention relates to a channel for laying pipelines for the heated fluid. These pipelines are laid in the channel in combination with the cables for the power supply. For each strip has a separate area of the channel. These zones 4 and 5 for different types of pads are interconnected through at least one hollow chamber 2, 6 and 8. 7 C. p. F.-ly. 3 Il. The invention relates to the channels for piping for the hot fluid in combination with cables for power supply, and for each strip, there is a special area of the channel.This channel is known from , which describes the conduit to be installed in residential premises. The channel consists of a U-shaped base and covering his opening Copacabana cover, while the U-shaped base is divided by a partition into two chambers: one chamber is used for laying cables and other pipelines for other environments.Pipelines for other environments can be water pipes, gas pipes or pipes of the heating system.To eliminate temperature propolene with the opportunity of putting on them, selectively cut in the longitudinal direction of the profiles of insulating material or enter into tubes in a shell of insulating material.The floor of the heating pipes insulation material has the great disadvantage that it is necessary to do throughout their length for an additional operation. Due to this, apart from the additional cost of material have significant installation cost, since it is necessary to isolate tees, bends, etc.In addition, this publication does not take into account influence of the temperature of the coolant in the pipes on the wiring.Described other comparable guide channel for different environments supply  , which is also divided by a partition into an area for wiring and the area of the heating pipes. In this publication, among other things said that the channel of the heat resistant up to 70oC plastic heating pipes should be insulated over its entire length. The channel of the heat-resistant up to 140oC plastic or metal pipe insulation can be generally unnecessary.This link can only be viewed as a disadvantage, since the heat pipes of the heating system here neglects is aniela should be in accordance with the heat pipes of the heating system. For example, the electric wire NYM 3 x 1.5 mm2when the gasket in the channel with two current-carrying conductors must be protected by a fuse of 15.5 And at an ambient temperature of 30oC. at 40oC the fun is reduced to 13,48 And, as at 60oC - 75 A. However, because of this flawless work of the consumers is not possible because, for example, a vacuum cleaner requires protection by a fuse of about 10A.The purpose of the invention is the creation of a channel for piping for the hot fluid in combination with the cables for the power supply.In addition, the invention consists in performing such a channel is convenient for installation, i.e., reduce the time of installation works on site.According to the invention for this purpose is proposed that the canal zone for different types of pads were connected into one unit through at least one hollow chamber. It is preferable that at least one of these cameras was placed insulating material which has a coefficient of thermal conductivity of 0.04 W/m K and its volume is calculated so that the temperature in the canal zone to power over its cross-section in the light did not exceed 25oC.Ooshima is no need to place any installation work, on the insulating foam.In the framework of the invention also lies this option, when in the hollow chamber placed fill her section in the light strip of foam. This strip of foam can be placed in the manufacture of the channel itself or subsequently. Minor works include then in the room of a strip of foam in the space provided for this purpose in the channel of the hollow chamber.In addition to insulation foam, at least one lateral wall of the hollow chamber may be provided with a heat-reflecting layer. Thus, if necessary, to reduce the thickness consisting of a foam insulating layer.Channel design according to the invention includes an integrated cross section of the channel insulating part, consisting preferably of a hollow chamber with a filling of foam. A layer of insulating foam may be placed in the hollow chamber at the time of manufacture of the channel, due to which both side walls of the hollow chambers are interconnected in the channel so that may be no need for additional stabilizing ribs. This task can also perform a strip of insulating foam P CLASS="ptx2">If, for example, in a hollow chamber of a width in the light of 10 mm to place polyurethane foam with a thermal conductivity of 0.035 W/m K, the temperature of the uninsulated pipes of the heating system at the input, component 90oC in the canal zone with the pipes of the heating system, is reduced to the 25oC in the area for wiring.If the width of the insulating chamber in the light of 20 mm and the use of polyurethane foam with a thermal conductivity of 0.04 W/m K for the temperature of the heating pipes at the entrance, which constitutes 90oC, the temperature in the area for wiring is reduced to a value of <25C.Both cameras for the strip, according to the invention, can be placed on top of each other or towards each other. It is important that both cameras are separated by a system of hollow chambers. System of hollow chambers may also consist, according to the invention, of several sequentially adjacent partial hollow chambers. To improve the insulating action filled, for example, air, partial hollow chambers they can be further subdivided offset from each other by partitions. System of hollow chambers can optionally contain the foam insulation, however, is optional.Crnom example 3 mm) strip of foam (in the depicted example, 13 mm thick) with a thermal conductivity of 0.035 W/m K, in order to reduce the temperature of the heating pipes on the entrance from the 70oC to 25oC in the area for wiring. Order acceptable reduction of heat radiation area of the heating pipes, can also be used a combination of several consecutive hollow chambers in the depicted example, the width in the light of 4 mm and with a heat-reflecting layer. The heat-reflecting layer can be formed, for example, in the form of aluminum foil, coating, lacquer coating, etc. can be located on the outer or on the inner wall of one or more hollow chambers.Channel according to the invention can be manufactured in one piece with both cameras to strip and separating the insulating part. However, in the framework of the invention also provides for the production of sections of channel separately from each other and, if necessary, their bond between a retainer or similar connecting elements.With these features combined, according to the invention, depending on the temperature of the heating pipes above the hollow chamber or chambers with foam insulation or without it and with a reflective layer or without it, the temperature in the area for wiring when attaching to the wiring channel.In Fig. 1 shows a channel with a Central hollow chamber and a filling of insulating material; Fig. 2 is a Central section of the channel with a hollow chamber of a small width in the light and a strip of insulating material of a smaller cross-section; Fig. 3 is a Central section of the channel with multiple hollow chambers without insulating material.In Fig. 1 shows channel 1 and U-shaped bottom part 11 and a lid 12.U-shaped bottom portion 11 consists of a bottom 111 and two side walls 112 and 113. In the Central zone U-shaped lower portion 11 of the molded walls 114 and 115 of the hollow chamber 2. A hollow chamber 2 filled with an insulating foam material 3, and this foam is connected to the inner surfaces of the walls 114, 115.In the hollow chamber 4 are uninsulated pipes 42, 41 of the heating system, and in the hollow chamber 5 - wires 51, 52, 53.In the framework of the invention provides the location in the hollow chamber 5 additional wires (not shown). The same applies to the additional pipe in the hollow chamber 4.In Fig. 2 shows only the Central section of the channel 1 with the special design of the insulating part. The insulating part is here from the hollow chamber 6 surrounded by walls 61 and 62. To the wall 61 adjacent the floor is of wires 51 - 53 in the chamber 5. The side walls 61 and 62 of the hollow chamber 6 inside and/or outside can be placed heat-reflecting layer (not shown).In Fig. 3 shows the Central section of the channel in Fig. 2 without strip 7 of insulating material. Instead, serve several hollow chambers 81 - 83, without forming additional strips of insulating material insulating part 8 between the hollow chambers 4, 5. Partial hollow chamber 81 - 83 have wall 811 - 813, which optionally may be additionally lined inside and/or outside heat-reflecting layers. Partial strip camera 81 - 83 further subdivided placed relative to each other by partitions 841 - 844, which, together with the thus created partial air chambers enhances the insulating effect between the hollow chambers 4 and 5. 1.
