Abstract

Offenbart ist ein Kühlmittelkreislauf eines Antriebs, beispielsweise eines Verbrennungsmotors, eines Hybridantriebs oder eines Elektroantriebs, bei dem Kühlmittel über einen Wärmespeicher auf Betriebstemperatur gebracht werden kann. Erfindungsgemäß wird als Speichermedium des Wärmespeichers Kühlmittel verwendet, wobei dieses auf eine Speichertemperatur erwärmt wird, die deutlich oberhalb der Betriebstemperatur des Kühlmittelkreislaufs liegt.

Figure imgaf001
Disclosed is a coolant circuit of a drive, for example an internal combustion engine, a hybrid drive or an electric drive, in which coolant can be brought to operating temperature via a heat accumulator. According to the invention, coolant is used as the storage medium of the heat accumulator, this being heated to a storage temperature which is significantly above the operating temperature of the coolant circuit.
