Assemblies for Electrical Machines

An assembly for an electrical machine comprising:

• a plurality of component modules;
• and
• electrically conductive inlet and outlet manifolds for conveying liquid dielectric coolant to and from the component modules and for one or more of supplying power to and receiving power from the component modules;
• wherein the inlet manifold is connected to a primary inlet and the outlet manifold is connected to a primary outlet;
• the component modules being fluid-tight housings containing liquid dielectric coolant, each housing including an inlet pipe connected to the inlet manifold and an outlet pipe connected to the outlet manifold such that liquid dielectric coolant is supplied to the inlet manifold through the primary inlet, is conveyed to each of the housings through the inlet pipes, is conveyed from each of the housings through the outlet pipes to the outlet manifold, and is then discharged through the primary outlet such that, in use, liquid dielectric coolant is circulated through each of the housings to cool power electronics components within each housing that are at least partially immersed in the liquid dielectric coolant.
