DE4434386A1 - Header arrangement on plastics pipe mat for building heating and cooling building - Google Patents

Abstract

The plastics pipe mat (1) comprises flexible plastics pipes coupled in parallel to a header via a flow connection. The flexible plastics pipes (6) are fitted to the headers (3,4) within the mat, with one header (3) forming the feed tube and the other (4) the outlet tube, in a single axis. The flexible plastics tubes form a loop (2) with a radius (R) of approx. 1/4 of the mat width. The headers may be closed by an end cap (5), which can also form their coupling.

Description

The invention relates to the formation 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 0 229 909, 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.

In both plastic tube mats shown, it is disadvantageous that the collecting tube is one occupies a high proportion of the total plastic tube mat. The manifold works but only slightly on the transferable power. The disadvantage is that high Material costs for plastic are due through the manifolds.

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, at the same time Plastic material costs per plastic tube area can be reduced and better Raw material utilization can be achieved.

The object is achieved in that within the plastic tube mat flexible plastic tubes are arranged on the header tubes, with a header tube as Supply pipe and the other manifold arranged as a discharge pipe in one axis  are, and the flexible plastic tubes are designed as a loop, the Loop radius takes up about 1/4 of the value of the mat width, that two collecting pipes are arranged on the plastic pipe mat, one collecting pipe as a feed pipe and another manifold as a drain pipe in one axis are arranged, and the flexible plastic tubes are designed as a loop, the Loop radius takes about 1/4 the value of the mat width.

An advantageous embodiment of the invention is that two header pipes through one End cap are closed, and the header pipes connected by the end cap are arranged.

The advantages achieved by the invention are in particular that the Plastic mats can be installed in cramped conditions while doing 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, the can Plastic material content per plastic tube mat can be reduced, with a better Raw material utilization is achieved.

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 tube mat 1 consists of flexible plastic tubes 2 , which are arranged integrally by welding on the header tubes 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 the flexible plastic pipes and arrives at the collecting pipe 4 . The flexible plastic tubes 2 are turned over to form plastic tube mats and the bending radius of the flexible plastic tubes is 1/4 of the value of the plastic tube mat. For better handling, it is useful if the header tubes 3 , 4 are closed by an end cap and are fixed in one axis by this end cap. The working medium passes from the collecting pipe 4 via a connecting line to the disposal line. Due to the design, the collecting tube only takes up a small amount of material per plastic tube mat and the overall height takes up the smallest realizable value due to the axial arrangement of the collecting tubes. The header pipes are only designed as large as necessary, and a plastic pipe mat has been created with a minimal use of plastic material.
