Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of installing bus bars in server cabinets is exacerbated by the differing mounting directions of power supplies and servers, particularly in immersion cooling systems where the blade server is vertically disposed, leading to installation inconveniences.
Innovation Solution
A bus bar assembly comprising a vertical and transverse bus bar configuration with conductive connecting plates, allowing power to be transferred from a vertical to a transverse direction, enabling perpendicular electrical connections between power supplies and servers without additional mounting components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the blade server is vertically disposed in the server cabinet for immersion cooling, then the cooling efficiency is improved, but the installation convenience of the bus bar is deteriorated due to the different mounting directions between the server and power supply
Solution Approach 1:
The bus bar structure transitions from a single-direction linear configuration to a multi-dimensional L-shaped configuration with vertical and transverse segments. This dimensional change allows the bus bar to accommodate both vertical server mounting and horizontal power supply connection, resolving the directional conflict between cooling requirements and installation convenience
Solution Approach 2:
The bus bar is divided into multiple segments including a vertical bus bar portion and a transverse bus bar portion, each serving specific directional functions. The vertical portion connects to the vertically-mounted server while the transverse portion connects to the power supply, allowing independent optimization of each segment for its specific function
2Reliability
If additional mounting components are used to connect power supply and server with different mounting directions, then the electrical connection reliability is improved, but the device complexity increases
Solution Approach 1:
The bus bar structure merges the functions of multiple separate mounting components into a single integrated L-shaped component. This unified structure simultaneously provides mechanical support, electrical connection, and directional adaptation, eliminating the need for additional mounting brackets, adapters, or fasteners while maintaining connection reliability
Solution Approach 2:
The bus bar is designed as a multi-functional component that simultaneously serves as an electrical conductor, mechanical support structure, and directional adapter. It handles both vertical and horizontal connections while providing structural support, reducing the overall component count and system complexity
