Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack a comprehensive solution to validate and test both electrical and mechanical systems in buildings, particularly in data centers, to ensure they can handle the demands of high-density computing equipment during commissioning and operation.
Innovation Solution
A liquid-cooled load bank system equipped with an electrical load cell and a mechanical load cell, controlled by a programmable controller, simulates the heat and pressure conditions of computing equipment to validate and test both systems, using a testing fluid that replicates the characteristics of computing equipment, with precise control over parameters like delta T temperature rise, delta P pressure drop, and flow rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate testing equipment is used for electrical and mechanical systems, then each system can be tested independently, but the validation process becomes time-consuming and inefficient
Solution Approach 1:
The patent combines electrical load testing and mechanical cooling system testing into a single integrated load bank unit. The electrical load cell generates heat that is dissipated by the mechanical cooling system, allowing simultaneous validation of both systems in one unified platform rather than requiring separate testing procedures.
Solution Approach 2:
The load bank serves multiple functions simultaneously: it acts as an electrical load device, a heat source, and a cooling system test platform. The same unit validates both electrical system capacity and mechanical cooling performance, making the testing equipment universal rather than specialized for a single function.
2Reliability
If real computing equipment is used for testing, then realistic operational conditions can be validated, but the testing process becomes complex and requires actual hardware deployment
Solution Approach 1:
The load bank creates a simplified thermal model that replicates the heat generation and cooling characteristics of actual computing equipment without requiring the physical hardware. The electrical load cell simulates the power consumption and heat output of IT equipment, allowing validation of cooling systems against realistic thermal loads through modeling rather than physical replication.
3Manufacturing precision
If comprehensive parameter control is implemented for delta T, delta P, and flow rate, then precise simulation of computing equipment characteristics is achieved, but the control system becomes more complex
Solution Approach 1:
The load bank incorporates sensors and control systems that continuously monitor delta T, delta P, and flow rate parameters, using feedback loops to maintain precise control over these variables. This allows the system to automatically adjust and maintain target parameters for accurate simulation of computing equipment thermal characteristics.
Solution Approach 2:
The system enables independent adjustment and control of multiple thermal parameters (delta T, delta P, flow rate) to match different computing equipment specifications. By allowing parameter changes rather than fixed operation, the load bank can simulate various IT equipment scenarios while maintaining precision through controlled variation of these key variables.

AI summary
A liquid-cooled load bank contains electrical and mechanical load cells to test and validate an electrical system with an electrical load and a mechanical system by heating a testing fluid in a circulation heater in the mechanical load cell and cooling of the mechanical load cell with the mechanical system in a building to validate the electrical system and the mechanical system of the building during a commissioning of the building. A programmable controller housed in the liquid-cooled load bank controls the power draw and the heating of the mechanical load cell to control parameters through the mechanical load cell. The parameters replicate and simulate characteristics corresponding to a set of computing equipment that the electrical system and the mechanical system of the building will support after the commissioning of the building. The programmable controller has a user interface to cooperate with a digital display to display the parameters.
