Claim 0:
1. A cooling plate apparatus, comprising:
a cooling body further comprising:
a top wall offset in an axial direction from a base wall;
a hub wall interposed between the top wall and the base wall;
a perimeter wall offset from the hub wall at a greater offset distance from a central axis than the hub wall, wherein the perimeter wall is interposed between the top wall and the base wall, connecting a perimeter of the top wall to a perimeter of the base wall;
the top wall, the base wall, the hub wall, the perimeter wall and the cooling body each comprising a heat conducting material;
an interior fluid cavity configured to hold and enable circulation fluid coolant, wherein the interior fluid cavity is defined by and disposed within an interior surface of the hub wall, an interior surface of the top wall, an interior surface of the base wall, and an interior surface of the perimeter wall;
a partition wall interposed between the top wall and the base wall, the partition wall configured to separate portions of the interior fluid cavity and enable a directional flow through the interior fluid cavity, and an aperture wall isolating the interior fluid cavity from a pass-through conduit for electrical wires that pass through and connect to an electric motor; and

a plurality of fasteners configured to fit a subset of a plurality of bores in the cooling body, the plurality of bores further defining one or more fluid inlets receiving fluid coolant into a first portion of the interior fluid cavity, and one or more fluid outlets dispensing fluid coolant from a second portion of the interior fluid cavity;
wherein the cooling plate apparatus is indirectly coupled to a cooling system of the electric motor, wherein the cooling body is interconnected with heat conducting components of the electric motor, thereby transferring heat from the electric motor to the cooling body by surface contact and conduction using the top wall, the subset of bores and the fasteners, wherein cooled fluid coolant is recirculated and the cooling plate apparatus generates a flow of fluid coolant through interconnected components in fluid communication comprising:
a coolant source, comprising one or more of coolant pumps, coolant reservoirs, coolant junctions, or coolant outlets;
an inlet line comprising a high-pressure line or fluid conduit that is removably connected to, and in fluid communication with, at a first end, the coolant source, comprising one or more of coolant pumps, coolant reservoirs, coolant junctions, or coolant outlets, and at a second end, an inlet fitting of the one or more fluid inlets of the cooling body configured to receive fluid coolant into the interior fluid cavity of the cooling body;
a central axis of the cooling plate apparatus, circulating within the interior fluid cavity in a direction from the fluid inlet to the fluid outlet, maintaining fluid contact with one or more of an interior surface of the hub wall, an interior surface of the top wall, an interior surface of the base wall, an interior surface of the perimeter wall, an interior surface of the partition wall, an interior surface of an aperture wall, or combinations thereof;
the interior fluid cavity of the cooling body of the cooling plate apparatus via a fluid outlet removably connected to, and in fluid communication with, a first end of an outlet line comprising a high-pressure line or fluid conduit via a fluid outlet fitting, wherein a second end of the outlet line is removably connected to, and in fluid communication with, the coolant source; and
thereby directing a flow of coolant from the coolant source, through the inlet line, into the cooling plate apparatus, into the interior fluid cavity of the cooling body of the cooling plate apparatus via the one or more fluid inlets, around the central axis of the cooling plate apparatus, in a direction from the fluid inlet to the fluid outlet, out of the interior fluid cavity via the fluid outlet through an outlet line via the fluid outlet fitting, back to the coolant source, cooling the electric motor and parts thereof by conduction, convection, radiation, and thereby transporting heat from the electric motor in an iterative cycle.
