Korrosionsschutz-Kühlmittelzusatz für WasserkühlsystemeAnti-corrosion coolant additive for water cooling systems

Im Bereich der Wasserkühlung von z.B. elektronischen Bauteilen werden üblicherweise neben destilliertem Wasser teilweise auch Wasser-Zusätze verwendet, die einen Korrosionsschutz bewirken sollen, aber eigentlich aus anderen technischen Anwendungsbereichen stammen (z.B. Kfz-Technik). Da die Bedingungen in derartigen Kühlsystemen sich zumeist deutlich von dem üblichen Einsatzbereich unterscheiden, sind die Mischungen nicht auf die Materialien und die Einsatzbedingungen optimiert und enthalten Mischungen von Stoffen, die entweder Korrosion nicht ausreichend verhindern (daher faktisch nicht geeignet sind), oder Reaktionen der Materialien bewirken, die die optischen Eigenschaften des Kühlsystems nachteilig beeinflussen.In the area of water cooling of electronic components, for example, in addition to distilled water, water additives are sometimes used that are intended to provide corrosion protection, but actually come from other technical areas of application (e.g. automotive technology). Since the conditions in such cooling systems usually differ significantly from the usual area of application, the mixtures are not optimized for the materials and the conditions of use and contain mixtures of substances that either do not sufficiently prevent corrosion (and are therefore not suitable) or cause reactions in the materials that adversely affect the optical properties of the cooling system.

Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, einen breit einsetzbaren Kühlmittelzusatz zu schaffen, der unter den in derartigen Kühlsystemen gängigen Bedingungen sowohl die Korrosion der Materialien des Kühlsystems wirksam verhindert als auch die Materialien in ihrem Aussehen unverändert lässt.The invention specified in the protection claim is based on the problem of creating a widely applicable coolant additive which, under the conditions common in such cooling systems, both effectively prevents corrosion of the materials of the cooling system and leaves the materials unchanged in their appearance.

Dieses Problem wird durch einen Kühlmittelzusatz nach den im Schutzanspruch aufgeführten Merkmalen gelöst.This problem is solved by a coolant additive according to the features listed in the protection claim.

Mit der Erfindung wird erreicht, dass die Lebensdauer des Kühlsystems, bei dem die Erfindung eingesetzt wird, sich erhöht und zusätzlich bei Systemen, deren optisches Erscheinungsbild von Belang ist, die optische Attraktivität erhalten bleibt.The invention achieves that the service life of the cooling system in which the invention is used is increased and, in addition, the optical attractiveness is maintained in systems whose optical appearance is important.
