Abstract

Official abstract text for this publication.

An electric generator including a number of electric accumulators and at least one heat-sink device using a phase-change material configured to pick up the excessive thermal energy produced by one of the electric accumulators and change phase in order to absorb a large quantity of thermal energy in the form of latent heat.

First claim

Opening claim text (preview).

1 . An electric generator comprising: a number of electric accumulators, at least one heat-sink device, each electric accumulator operating over a range of operating temperatures bounded by lower and upper values and having a critical temperature beyond which the electric accumulator can be damaged, the heat-sink device comprising at least one container comprising a phase-change material, the container being positioned above at least one electric accumulator, the phase-change material having a phase-change temperature lying between the upper value of the range of operating temperatures of the electric accumulator and the critical temperature of the electric accumulator, the container being delimited by at least one wall oriented toward the electric accumulator and produced from a material having a melting temperature higher than or equal to the upper value of the range of operating temperatures of the electric accumulator and lower than or equal to the critical temperature of the electric accumulator. 2 . The electric generator as claimed in claim 1 , wherein, at the phase-change temperature, the phase-change material is configured to transition from a liquid state to a gaseous state. 3 . The electric generator as claimed in claim 1 , wherein the melting temperature is lower than the phase-change temperature of the phase-change material. 4 . The electric generator as claimed in claim 1 , wherein the upper value of the range of operating temperatures of the electric accumulator is lower than or equal to 80° C. 5 . The electric generator as claimed in claim 1 , wherein the critical temperature of the electric accumulator lies between 120° C. and 140° C. 6 . The electric generator as claimed in claim 1 , wherein the phase-change material comprises water. 7 . The electric generator as claimed in claim 6 , wherein the phase-change material includes at least one additive.
