Description

Mittel zur Verhinderung übermäßiger Wärmebeeinflussung von Körpern, welche von Medien hoher, ihnen schädlicher Wärme umspült werden. Gegenstand vorliegender Erfindung ist ein Mittel zur Verhinderung übermäßiger Wärmebeeinflussung von Körpern, z. B. der Zylinderwandungen von Verbrennungskraftmaschinell u. dgl. Ohne einen solchen Wärmeschutz würden diese Körper von den sie umspülenden Gasen oder Flüssigkeiten stark angegriffen werden. Bisher wurden die der Hitze ausgesetzten Körper durch Umspülen mit einem kühlenden Medium gegen allzu hohe Temperaturen geschützt. Es war bisher allgemein üblich und vor allem auch notwendig, die mit den Verbrennungsgasen in Berührung kommenden Wandungen usw. gegen den Temperatureinfluß der hocherhitzten Gase bei kleinen Maschinen durch Luft mittels Kühlrippen zu schützen. Bei mittleren Maschinen müssen die wichtigsten Teile und bei Großmaschinen, hauptsächlich bei Dieselmotoren, müssen sämtliche berührten Wandungen durch Wasserkühlung geschützt werden. Dies bildet eine kostspielige und komplizierte Gestaltung der ganzen Maschinenanlage, die durch vorliegende Erfindung in einfacher Weise erübrigt wird. Das neue 'Mittel besteht darin, daß die der Wärme ausgesetzte: Flächen und Teile der Maschine mit einer fest anhaftenden 1Taterialschicht von sehr geringer Wärmeleituiigsfähigkeit, etwa Email, verseben werden.Means to prevent excessive heat influence on the body, which are surrounded by media of high, harmful heat. Subject of the present Invention is a means of preventing excessive heat influence on bodies, z. B. the cylinder walls of internal combustion engines and the like. Without such These bodies would provide thermal protection from the gases or liquids flowing around them be severely attacked. So far, the bodies exposed to the heat have been through Rinsing with a cooling medium protected against excessively high temperatures. It was previously common and especially necessary with the combustion gases walls etc. coming into contact against the temperature influence of the highly heated To protect gases in small machines with air by means of cooling fins. At middle Machines have the most important parts and, in the case of large machines, mainly for Diesel engines, all exposed walls must be protected by water cooling will. This constitutes an expensive and complicated design of the whole machinery, which is dispensed with in a simple manner by the present invention. The new 'means consists in the fact that those exposed to heat: surfaces and parts of the machine with a firmly adhering material layer of very low thermal conductivity, e-mail, for example.

Der Vorgang bei der bekannten Außenkühlung ist der, daß die von der Wandung aufge-iomme:_e Wärme an das Kühlmittel abgegeben und durch dieses abgeführt wird. Der Vorgang bei der Neuerung gemäß vorliegender Erfindung ist etwa der folgende: Während der Verdichtung, Verbrennung mit Ausdehnung und Entleerung kann die wärmeschützende Schicht nur eine geringe Wärmemenge von den heißen Gasen aufnehmen, um sie bei der Einströmung des kalten, frischen Gasgemisches an letzteres wieder abzugeben. Die übriggebliebene Wärme kann durch die anschließende Wandung vermöge deren höherer Wärmeleitungsfähigkeit leicht abgeführt werden. Die ausstrahlende und dadurch verlorengehende Wärme wäre somit auf ein Mindestmaß herabgedrückt und damit ein ökonomisches Arbeiten gewährleistet.The process in the known external cooling is that of the Wall absorbed: _e heat given off to the coolant and dissipated through it will. The process in the innovation according to the present invention is roughly as follows: During compression, combustion with expansion and emptying can be the heat protective To absorb only a small amount of heat from the hot gases in the layer To release the inflow of the cold, fresh gas mixture to the latter again. the Remaining heat can pass through the subsequent wall by virtue of its higher level Thermal conductivity can be easily dissipated. The radiating and thus lost Heat would thus be reduced to a minimum, making it economical to work guaranteed.

Bei anderen Maschinen oder Vorr ichtungen wird naturgemäß der gleiche Vorteil erreicht.With other machines or devices, the same will of course be the case Advantage achieved.
