Abstract

The aluminum extruded section can be used for heat transfer and heat storage simultaneously. The heat energy of a medium flowing through (liquids, gases) is delivered to chambers of the heat-storing material. The heat energy of a heat-storing material is delivered to the environment during a longer period. The heat energy is extracted from any warmed up medium (liquids, gases). The heat accumulators depend upon the temperature of the medium flowing through the heat-storing material and can be filled with flowing through medium.

Description

Latentwärmespeicher sind Speichermaterialien wie Salzhydrate oder Paraffine, die ähnlich wie Eiswürfel funktionieren. Kommt ein Medium mit einer höheren Temperatur in Kontakt mit dem Speichermaterial, wird dem Medium Wärme entzogen, bis das Speichermaterial schmilzt. Dabei bleibt die Temperatur des Speichermaterials konstant.Latent heat storage are storage materials such as salt hydrates or paraffins that work much like ice cubes. If a medium comes with a higher one Temperature in contact with the storage material, the medium becomes Heat withdrawn, until the storage material melts. The temperature of the Storage material constant.

Die Idee ist, den Wärmeübergang des Aluminium-Strangpressprofils (1, 2, 3) für gelegentlich auftretende Abwärme von Gasen oder Flüssigkeiten zu nutzen.The idea is to control the heat transfer of the extruded aluminum profile ( 1 . 2 . 3 ) for occasional waste heat from gases or liquids.

Dabei wird das in den Kammern (1) des Aluminium-Strangpressprofils (1, 2, 3) befindliche Speichermaterial durch die Abwärme des durchströmenden Mediums geschmolzen und gibt über längere Zeit über das Profil (1, 2, 3) die Wärmeenergie an die Umgebung ab. Das jeweils zum durchströmenden Medium passende Speichermaterial wird dazu eingesetzt.This is done in the chambers ( 1 ) of the aluminum extruded profile ( 1 . 2 . 3 ) melted by the waste heat of the medium flowing through and gives over a longer time on the profile ( 1 . 2 . 3 ) the heat energy to the environment. The storage medium suitable in each case for the medium flowing through is used for this purpose.

Z.B. hat das durchströmende Medium hat eine Temperatur von ca. 80°C, dann muss das Speichermedium aus Paraffin bestehen. Bei einer niedrigeren Temperatur ist das optimale Speichermedium ein Salzhydrat oder ein Gemisch aus Salzhydrat und Paraffin.For example, has the flowing through Medium has a temperature of about 80 ° C, then the storage medium made of paraffin. At a lower temperature this is optimal storage medium is a salt hydrate or a mixture of salt hydrate and paraffin.

Das optimale Speichermaterial weist eine hohe Zyklenfestigkeit auf und ist langlebig.The optimal storage material has a high cycle resistance and is durable.

Die Funktionsweise des Aluminium-Strangpressprofils (1 und 3) ist dabei wie folgt:

  • – Ein warmes Medium durchströmt den inneren Kanal des Profils und gibt über die Kühlrippen (2) die Wärmeenergie an das Aluminium-Strangpressprofil ab.
  • – Das sich in den Kammern (1) befindliche Speichermatertal (Salzhydrat oder Paraffin) wird zum Schmelzen gebracht und speichert die Wärme über einen längeren Zeitraum.
  • – Über die äußeren Kühlrippen (3) wird die Wärmeenergie in diesem längeren Zeitraum konstant an die Umgebung abgegeben.
  • – Die Zufuhr des warmen Mediums und die Abfuhr des abgekühlten Mediums erfolgt dabei über Rohranschlussstutzen (4), die im Profil angeschraubt werden (4).
The functioning of the aluminum extruded profile ( 1 and 3 ) is as follows:
  • - A warm medium flows through the inner channel of the profile and passes over the cooling fins ( 2 ) the heat energy to the aluminum extruded profile from.
  • - That in the chambers ( 1 ) is melted and stores the heat over a longer period of time.
  • - over the outer cooling fins ( 3 ) the heat energy is constantly released to the environment in this longer period of time.
  • - The supply of the warm medium and the removal of the cooled medium takes place via pipe connection piece ( 4 ), which are screwed into the profile ( 4 ).
