The invention concerns a device for thermal regulation (), in particular cooling, for an electronic component (), in particular a battery, the temperature of which must be controlled, the electronic component () being in particular capable of giving off heat during its operation, the thermal regulation device comprising at least one first circuit () configured to allow the circulation of a heat transfer fluid; at least one second circuit () configured to transport a dielectric fluid, this second circuit comprising at least one outlet for delivering the dielectric fluid towards the electronic component; at least one first circuit () and at least one second circuit () being arranged so that the first circuit is in thermal interaction with the fluid delivered via the at least one outlet of the second circuit.

Device for thermal regulation of an electronic component

A battery includes at least one row of energy storage cells. The row of energy storage cells has a longitudinal extension direction with an upper side and lateral sides being respectively defined by a series of upper and lateral faces of the energy storage cells and of spaces separating the energy storage cells in the longitudinal extension direction. The battery also includes a dielectric fluid circuit with one or more spray orifices. The spray orifices are flush with the upper side of the row of energy storage cells and are located facing a lateral side of the row such that the dielectric fluid circuit leaves the upper side of the row free.
