Description

The present invention relates to a capillary tube heat exchanger structural member for surface tempering, a corresponding manufacturing method and a capillary tube heat exchanger structural member arrangement.Prior ArtThe tempering of rooms with tempering fluid-conducting surface heating systems via thermal radiation has in the meantime played a supporting role in the fitting of new and existing buildings. A large heat transfer surface and low flow temperatures are especially suitable for heat pump systems and for regenerative systems.It is generally known to use capillary tube mats for the surface tempering of rooms, i.e. for cooling and / or heating the rooms. A capillary tube mat is generally known and is a planar composite of thin tubes (capillaries) with a respective end collecting tube.Capillary tube mats of this type effectively and space-savingly distribute heat closely below the surface of walls, ceilings or floors. They thus follow a natural pattern, because fine blood vessels below the surface of the skin ensure a heat regulation even in the human body.A capillary ear mat is described, for example, in DE 44 33 392 A1. In this case, the capillary tube mat has a multiplicity of capillary tubes which are arranged perpendicularly to one or more collecting tubes and during operation of the capillary tube mat from a temperature-controlled working medium (i.e. Water) can be passed through. The capillary and collecting pipes are made of a plastic which is easily thermally weldable and thus enables a secure, positive connection of capillary and collecting pipes by means of welding.WO 98 / 05 905 A1 discloses a capillary tube heat exchanger structural plate having a rigid, lightweight, in particular foamed, hard disk (rigid foam plate), in which capillary tubes running parallel in many parallel grooves are inserted and are covered with a thin layer of a concrete mixture having continuous reinforcing fibers or a reinforcing fiber mat inserted therein.It is known in particular to apply capillary tube mats directly to a surface and to cover them with cover plates. Also known are prefabricated capillary tube heat exchanger elements which have a sandwich construction from a gypsum board with a deposited capillary tube mat embedded in a polystyrene heat insulation.The known systems with capillary tube mats are often difficult to install by non-experts, in particular corresponding capillary tube heat exchanger building elements have a high dead weight or a large thickness.Disclosure of the InventionThe present invention provides a capillary tube heat exchanger panel assembly according to claim 1, a corresponding manufacturing method according to claim 18 and a capillary tube heat exchanger panel assembly according to claim 23.Preferred refinements are the subject matter of the respective dependent claims.Advantages of the InventionThe idea underlying the present invention is that the first collecting tube is clamped in the first transverse groove by means of a first clamping device and the second collecting tube is clamped in the second transverse groove by means of a second clamping device in such a way that the collecting tubes and the capillary tubes run exposed on the first main surface, wherein the capillary tubes are under tension. On the first main surface, a respective transition region is provided between the longitudinal grooves and the first transverse groove and between the longitudinal grooves and the second transverse groove, which transition region has a respective region, which slopes in the direction of the transverse grooves, between the longitudinal grooves and the transverse grooves, over which the clamped capillary tubes run, so that the capillary tubes have a respective end section, which slopes in the direction of the first and second collecting tubes in accordance with the slope.The surface tempering capillary tube heat exchanger structural blank according to the invention according to claim 1 and the corresponding manufacturing method according to claim 18 and the capillary tube heat exchanger structural blank arrangement according to claim 23 thus allow to provide a compact, stable and lightweight capillary tube heat exchanger structural blank which is also easily installable by non-experts and which offers variable design possibilities on the exposed first main surface, e.g. by over-cleaning, filling or lining with other arbitrary heat conducting cover materials. Due to the special configuration of the clamping of the collecting tubes and the tension stress thereby applied, which acts on the capillary tubes, a stable bond without production tolerance effects results. Due to the decreasing region between the longitudinal grooves and the transverse grooves over which the clamped capillary tubes run, the tensile stress receives a component parallel to the first main surface and a component perpendicular to the first main surface. The descending region also prevents the capillary tubes from bending or clamping off at the edge of the transverse grooves during clamping.In particular, the production method according to the invention facilitates automated reliable production, wherein tolerances of the insulation support plate and the capillary tube mat can be compensated by the steps of stretching the capillary tubes and restretching the capillary tubes after proper insertion, and at the same time an appropriate tensile stress can be set.According to a preferred embodiment, the falling region has one or more stages.
