2 . The data center apparatus of claim 1 , wherein the folded trapezoidal sheet is obtained by cutting a rectangular sheet of conductive metal in two half sheets, wherein each half sheet corresponds to a half of a trapezoids, and folding each half sheet around a longer leg of the respective trapezoid for multiple folds such that each half sheet is wrapped about the longer leg of the respective trapezoid.
3 . The data center apparatus of claim 2 , wherein a longer parallel edge of each trapezoid is folded such that the two longer parallel edges of two trapezoids made from the two half sheets form a top surface of the at least one busbar, and a shorter parallel edge of each trapezoid is folded such that the two shorter parallel edges of the two trapezoids form a bottom surface of the at least one busbar.
4 . The data center apparatus of claim 2 , wherein two folded trapezoids made from the two half sheets are placed inside the at least one busbar, wherein the at least one busbar is a busbar conductor for conducting electricity to an electronic device connected to the busbar conductor.
5 . The data center apparatus of claim 2 , wherein at least one folded trapezoid has a triangular cross-section taken perpendicular to a longitudinal axis of the busbar.
6 . The data center apparatus of claim 1 , wherein the at least one busbar is mounted on a rack that is electrically coupled to a power supply.
7 . The data center apparatus of claim 1 , wherein the conductive metal is copper or aluminum.
8 . A method of configuring at least one busbar, comprising: coupling at least one busbar having a hollow structure shaped from a folded trapezoidal sheet of conductive metal being folded around a longitudinal axis to define at least one hollow interior, to a power supply, wherein the hollow structure is placed inside a busbar frame in a position at which the longitudinal axis of the hollow structure is vertical, and a top portion of the hollow structure has a top cross section with a greater area than a bottom cross section of a bottom portion of the hollow structure.
9 . The method of claim 8 , wherein the folded trapezoidal sheet is obtained by cutting a rectangular sheet of conductive metal in two half sheets, wherein each half sheet corresponds to a half of a trapezoids, and folding each half sheet around a longer leg of the respective trapezoid for multiple folds such that each half sheet is wrapped about the longer leg of the respective trapezoid.
10 . The method of claim 9 , wherein a longer parallel edge of each trapezoid is folded such that the two longer parallel edges of two trapezoids made from the two half sheets form a top of the at least one busbar, and a shorter parallel edge of each trapezoid is folded such that the two shorter parallel edges of the two trapezoids form a bottom of the at least one busbar.
11 . The method of claim 9 , further comprising: placing two folded trapezoids made from the two half sheets inside a busbar frame, wherein the at least one busbar is a busbar conductor for conducting electricity to an electronic device connected to the busbar conductor.
12 . The method of claim 9 , wherein at least one folded trapezoid has a triangular cross-section taken perpendicular to a longitudinal axis of the busbar.
13 . The method of claim 8 , further comprising:
mounting the at least one busbar on a rack that is electrically coupled to the power supply.
14 . The method of claim 8 , wherein the conductive metal is copper or aluminum.
15 . A method of manufacturing at least one busbar, comprising:
shaping at least one busbar having a hollow structure by folding a trapezoidal sheet of conductive metal around a longitudinal axis to define at least one hollow interior; and
placing the hollow structure inside a busbar frame on a data center rack in a position at which the longitudinal axis of the hollow structure is vertical, wherein a top portion of the hollow structure has a top cross section with a greater area than a bottom cross section of a bottom portion of the hollow structure.
16 . The method of claim 15 , wherein the folding the trapezoidal sheet of conductive metal further comprises:
cutting a rectangular sheet of conductive metal in two half sheets, wherein each half sheet corresponds to a half of a trapezoids, and
folding each half sheet around a longer leg of the respective trapezoid for multiple folds such that each half sheet is wrapped about the longer leg of the respective trapezoid.
17 . The method of claim 16 , wherein a longer parallel edge of each trapezoid is folded such that the two longer parallel edges of two trapezoids made from the two half sheets form a top of the at least one busbar, and a shorter parallel edge of each trapezoid is folded such that the two shorter parallel edges of the two trapezoids form a bottom of the at least one busbar.
18 . The method of claim 16 , further comprising:
placing two folded trapezoids made from the two half sheets inside a busbar frame, wherein the at least one busbar is a busbar conductor for conducting electricity to an electronic device connected to the busbar conductor.
