METHOD AND ARRANGEMENT FOR SWITCHING OFF A HEAT EXCHANGER OPERATED IN THE EXHAUST FLOW OF A COMBUSTION ENGINE WITH A FLOWABLE HEAT EXCHANGER

摘要

For the disconnection of a heat transfer circuit placed in the exhaust gas flow path of an IC engine and containing a flowable heat vehicle liquid connecting with a heat absorbing means, the said vehicle fluid is withdrawn from the heat exchanger and transferred to a storage means, whence it may be transferred back to the heat exchanger when same is to be reconnected.
