Embodiments of busbar assemblies for use in immersion cooling apparatuses are described herein. In one embodiment, a busbar assembly may include an insulator block and a busbar. The insulator block may include a first barrier having a first barrier height, a second barrier having a second barrier height, a channel located between the first barrier and the second barrier, and a slot formed in the channel. The busbar may be positioned in the slot and have an effective busbar height that is less than the first barrier height and less than the second barrier height. Other examples may be described and claimed.

Disclosed herein is a novel bus bar design for use with double-sided cold plates. The bus bar has a ‘symmetry’ such that the same bus bar can be used, depending on its orientation, to connect on either side of the cold plate. Thus, two identically formed bus bar parts, with one of the parts rotated through 180 degrees relative to the other, can be interconnected to form a bus bar assembly. This can reduce unique part counts.

A propulsion system for an aircraft can include an electric power source and an electric propulsion assembly having an electric motor and a propulsor. The propulsor can be powered by the electric motor. An electric power bus can electrically connect the electric power source to the electric propulsion assembly. The electric power source can be configured to provide electrical power to the electric power bus. An inverter converter controller can be positioned along the electric power bus and can be electrically connected to the electric power source at a location downstream of the electric power source and upstream of the electric propulsion assembly.

A thermally conductive bracket is contemplated for use in a vehicle to facilitate transfer heat from a busbar to a cold plate, such as to assist with heat transfer to a cold plate used to act as a heat sink for a plurality of battery cells connected to the busbar. The bracket may include a thermally conductive heat transfer material shaped to receive the busbar where at least a portion of the material is configured to include opposed sides and a bottom such that the opposed sides are configured to transfer heat from the busbar to the bottom and the bottom is configured to transfer heat from the sides to the cold plate.
