DE4434387A1 - Header arrangement on plastics pipe mat for building heating and cooling system - Google Patents

Abstract

The plastics pipe mat (1) has several flexible plastics pipes (7), fitted in parallel to the headers (2-4) via a flow connection. The plastics pipes are fitted to three headers within the mat, with one header (3) forming the feed pipe and another (4) the outlet pipe, in a single axis. The headers (3,4) may contain a closure end cap (5) which may also form their coaxial coupling. One header (2) may contain a closure (6) on either side.

Description

The invention relates to the arrangement of manifolds on a plastic tube mat for the Heating and cooling of buildings and for use in heat exchangers, the Plastic pipe mat from a number parallel to the collecting pipe through a material connection Connection arranged flexible plastic pipes exists.

From DE 44 25 785.6 plastic pipe mats are known in which the collecting pipes Limit plastic pipe mat. Plastic pipe mats are made by adding and Disposal lines supplied with the working medium. This feed and Disposal lines are installed together and are often on one side of the Plastic pipe mat. This arrangement is favorable when pressing the Plastic pipe mats after assembly, because the arrangement chosen folds down is possible when recessed into the ceiling. The disadvantage of this embodiment is that one of the two supply lines must have at least the length of the plastic pipe mat. Long connecting hoses are therefore often used to connect the plastic pipe mat to the supply lines with the working medium necessary. Through the hoses the flow resistance negatively affects and the efficiency of the plastic tube mat is deteriorating.

A plastic pipe mat is shown in E 0229 909, with the collector pipes on arranged on one side of the plastic tube mat. Short connection hoses can be used here be used to the supply lines. A disadvantage of this version is however, that a great height is achieved by the arrangement of the header pipes, which can often have an adverse effect on suspended ceilings. Also with this Disadvantageous arrangement that the overhead manifold on a part of the thin flexible plastic pipes. With loads, e.g. B. when connecting the Connecting hoses can damage the flexible plastic pipes below will.

The invention has for its object to form a plastic tube mat in the the connection options are created so that only short connecting hoses to Connection to the supply lines are necessary so that the flow resistance is not increased unnecessarily, the overall height of the plastic tube mat Diameter of the collecting pipe does not exceed, and the violation of the flexible Plastic pipes through the manifolds is not given.

The object is achieved in that within the plastic tube mat the flexible plastic tubes are arranged on three manifolds, one Manifold as a feed pipe and another manifold as a drain pipe in one Axis are arranged.

An advantageous embodiment of the invention is that a End cap is arranged sealingly, and the manifolds through the end cap in one Axis are connected.

Another advantageous embodiment of the invention is that on a manifold a closure is arranged on both sides.  

The advantages achieved by the invention are in particular that the Plastic mat can be installed in tight spaces, while being short Connection hoses can be used, which has a positive effect on the Flow resistance affects, in addition, through the formation of the Plastic tube mat ensures that the flexible plastic tubes cannot pass through it arranged manifolds can be injured.

An embodiment of the invention is shown in the drawing and in the following described in more detail.

The drawing shows a schematic representation of the invention Plastic pipe mat.

The plastic pipe mat 1 consists of flexible plastic pipes which are arranged integrally by welding on the collecting pipes 2 , 3 , 4 . When the plastic pipe mats 1 are used , the working medium reaches the collecting pipe 3 from the supply line and the connecting line through connections (not shown ) . From here it flows through part of the flexible plastic pipes and reaches the collecting pipe 2 . The header tube 2 is sealed tightly by two side closures 6 . The working medium flows through the remaining part of the flexible plastic pipes to the collecting pipe 4 . The working medium then reaches the disposal line via the connecting line.

A minimal overall height is achieved due to the plastic mat design. With the short connecting lines can be due to the good flow with the Good transfer values can be realized for the plastic pipe mat.
