Abstract

An accumulator (20) operating according to the layered storage principle is used in connection with the cooling loop of a vehicle, and includes charge alternation devices (34, 38) adapted to upper and lower storage regions (26, 28). The inflow and outflow velocity of the coolant should be between 0.1 and 0.5 m/s, and charging or discharging of the accumulator (20) should occur within 10 to 100 seconds. Inflow and outflow lines (32, 36) run within an insulation space (40) in the fashion of a thermosiphon.
