Abstract

In operation of fluid cooled combustion motors, which have ducts, in which the coolant is circulated to transport heat away from the pump head and cylinders, as well as to reach a uniform temperature in the motor block. When operational temperature is reached, the thermostat opens and the fluid is pumped out in the cooler (heat exchanger, fluid/air) where it is cooled. Accumulation: When the combustion motor has reached operational temperature, a part of the excess heat is led through the thermo-anti-self-circulation system to the storage tank. The system is shunted into the combustion motor's cooling system (for example on the heating apparatus' tubing, with T pieces). Energy supply: the thermo-anti-self-circulation system's electric fluid pumps are activated, this transports the warm fluid from the storage container to the motor's cooling ducts, which warm the pump head and the cylinder(s).<IMAGE>

Den foreliggende opfindelse ( varmelagring i fartøjer ) angår et kølesystem ved væskekølet forbrændingsmotor, hvis motorblok har kanaler for cirkulerede kølervæske, og med en isoleret lagerbeholder og en pumpe, hvormed kølervæsken kan ledes fra motorblokkens kanaler til lagerbehoIderen via en første ledning og fra lagerbeholderen tilbage til motorblokkens kanaler via en anden ledning.The present invention (vessel heat storage) relates to a liquid-cooled internal combustion engine cooling system whose engine block has circulating coolant channels, and with an insulated storage tank and pump, through which the coolant can be fed from the engine block's channels to the storage container via a first conduit and back from the storage container. the channels of the engine block via a different wire.

Ved koldstart af en forbrændingsmotor er brændstofforbruget og motorslidtagen forøget i opvarmningsperioden.At the cold start of an internal combustion engine, fuel consumption and engine wear are increased during the heating period.

Til imødegåelse af dette er det kendt eksempelvis fra norsk fremlæggelsesskrift nr. 150.012, at man, når motoren er varm, leder opvarmet kølervæske til en isoleret lagerbeholder, og at man, inden motoren atter startes, leder kølervæske fra lagerbeholderen tilbage til motorens kanaler.To counter this, it is known, for example, from Norwegian publication no. 150.012 that when the engine is hot, heated coolant is led to an insulated storage tank and that before the engine is restarted, coolant from the storage container is returned to the engine ducts.

Ved denne fremgangsmåde opnår man, så længe kølervæsken i lagerbeholderen er varm, at motorblokken opvarmes inden start, således at man modvirker de med koldstart forbundne ulemper.By this method, as long as the coolant in the storage tank is hot, the engine block is heated before starting, so as to counteract the disadvantages associated with cold start.

Ifølge den foreliggende opfindelse foreslås, at de to ledninger er spiralviklet mindst en gang om lagerbeholderens vandrette akse.According to the present invention, it is proposed that the two wires are spirally wound at least once about the horizontal axis of the storage container.

Ved denne udformning vil temperaturforskellen mellem varm væske i toppen af ledningssystemet og kold væske i bunden effektivt forhindre muligheden for selvcirkulation. Som følge heraf er den opvarmede kølervæske i beholderen isoleret fra den afkølede væske i motorblokkens kanaler, indtil pumpen aktiveres.In this design, the temperature difference between hot liquid at the top of the conduit system and cold liquid at the bottom will effectively prevent the possibility of self-circulation. As a result, the heated coolant in the container is isolated from the cooled liquid in the ducts of the engine block until the pump is activated.

Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, som i perspektiv viser en isoleret lagerbeholder med forbindelsesledninger for et kølesystem ifølge opfindelsen.The invention will now be explained in more detail in connection with the drawing, which shows in perspective an isolated storage container with connection lines for a cooling system according to the invention.

Den viste lagerbeholder (1) anvendes i forbindelse med en ikke vist forbrændingsmotor, hvis motorblok har kanaler for cirkulerende kølervæske. Lagerbeholderen er via to ledninger ( 2 og 3) forbundet med motorblokkens kanaler, således at kølervæske ved hjælp af en pumpe, evt. motorens sædvanlige vandpumpe, kan ledes til og fra beholderen.The shown storage tank (1) is used in connection with an internal combustion engine (not shown), whose engine block has circulating coolant channels. The storage container is connected to the ducts of the engine block via two wires (2 and 3), so that coolant is pumped by means of a pump, possibly. the engine's usual water pump can be routed to and from the container.

De to ledninger ( 2 og 3 ) er viklet mindst en gang om lagerbeholderens (1) vandrette akse, således at sevcirkulation forhindres.The two wires (2 and 3) are wound at least once about the horizontal axis of the storage container (1) to prevent seepage circulation.
