- the nozzles 11, 1 ia, 11b when they are multi-jets, make it possible to reduce the number of nozzles 11, 1 ia, 11b, and therefore the cost of the regulation device 3, while allowing a homogeneous spraying of the dielectric fluid on the surfaces of the modules 7.
- the arrangement of the nozzles 11, 1 ia, 11b are studied for a homogeneity of spraying of dielectric fluid on the surfaces of the modules 7.
- these arrangements allow to improve the thermal regulation, such as the cooling, of the upper surfaces 71 but also of the side surfaces 73, 75, of the modules, to ensure homogeneous cooling of the modules 7.
