COOLING ARRANGEMENT FOR AN ELECTRICAL STORAGE DEVICE ALLOWING GRADED OR VARIABLE LOCAL COOLING

摘要

A cooling arrangement (100) for cooling a heated surface of an electrical energy storage device. The cooling arrangement comprises a conduit (110) with a length, a wall (111), an inlet (121), and an outlet (122). The inlet is configured to receive a coolant and the outlet is configured to exhaust the coolant, thereby forming a coolant path (120) between the inlet (121) and the outlet (122). The conduit (110) is configured to transfer heat from the heated surface to the coolant along the coolant path (120) with an associated heat transfer rate, which is dependent on a heat conduction property of the wall (111) of the conduit (110). The wall of the conduit is arranged with variable heat conduction property, where the heat conduction property varies in dependence of a configuration of the electrical energy storage device.
