Abstract
A two-phase immersion cooling system includes two or more voltage converters and a plurality of circuit boards, which are held in a modular case inside an immersion tank. A layout for distributing electric power includes at least two busbars that are electrically connected in parallel to the positive and the negative terminals of the voltage converters, respectively. Each of the plurality of circuit boards is connected to the two busbars via wires that are bundled into wire harnesses. Each wire harness connects a series of connectors longitudinally aligned across the plurality of boards, to the two busbars.
