Abstract: A method for manufacturing an ignition coil for an internal combustion engine includes manufacturing a containment body provided with a containment chamber, defining an internal volume, and with a lateral seat facing outwards, and preparing an electronic board provided with a first face and a second face, opposite the first. The electronic board is positioned inside said lateral seat and a polymeric material with high thermal conductivity is then printed on the electronic board so as to cover it.

Abstract: The present invention relates to the use of a composition including a mixture of at least two waxes belonging to the class of phase change materials (PCMs) as an element for accumulating latent heat in an electric machine, preferably for automotive use. In one embodiment, the composition is contained inside a hollow cooling casing of an electric machine, preferably for automotive use. The present invention also relates to a method for producing a hollow cooling casing containing said composition and for cooling an electric machine which includes the use of said cooling casing.

Abstract: A coolant housing for an electric machine, preferably for automotive use, includes a hollow body extending around its own central axis and provided with a radially internal wall, delimiting a reception volume of an electric machine, and a radially external wall. The housing further includes a cavity delimited between the radially internal wall and the radially external wall and containing at least one latent heat storage element arranged inside said cavity.
