Electrical Cabinet Architecture Selection for Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to determine an optimal electrical cabinet architecture that minimizes cooling requirements, often leading to oversizing of refrigeration units and increased electrical consumption due to difficulties in apprehending a priori refrigeration needs and evaluating thermal zone temperatures.
Innovation Solution
A method is implemented to select an electrical cabinet architecture by searching for a 'passive' architecture where temperatures in thermal zones are maintained without cooling, and if that is not possible, an 'economical' architecture is selected that reaches setpoint temperatures with the minimum cooling capacity, using computational simulations to determine the required cooling power and architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling power is injected into the cabinet to maintain thermal zone temperatures, then the temperatures in thermal zones are maintained at optimal levels, but the electrical consumption of the cabinet increases
Solution Approach 1:
The patent performs preliminary thermal simulations during the design phase to evaluate different cabinet architectures and identify configurations that minimize cooling requirements. By calculating temperature distributions and cooling powers for multiple architectural options before finalizing the design, the system selects architectures that naturally maintain optimal thermal zones with reduced cooling input, thereby resolving the contradiction between temperature maintenance and energy consumption.
2Reliability
If the refrigeration units are oversized to ensure adequate cooling capacity, then the cooling needs are met, but the electrical consumption increases
Solution Approach 1:
The patent changes the architectural parameters of the cabinet (such as insulation properties, thermal zone configurations, and component arrangements) to optimize thermal performance. By adjusting these parameters during the design phase through simulations, the system identifies configurations that reduce the required cooling capacity, allowing for properly sized refrigeration units that meet cooling needs without excessive electrical consumption.
3Use of energy by stationary object
If thermal simulations are performed for multiple architectures to identify optimal cooling strategies, then the cooling requirements are optimized, but the complexity of the selection process increases
Solution Approach 1:
The patent creates simplified thermal models that replicate the thermal behavior of different cabinet architectures. These models use reduced-order simulations that capture essential thermal characteristics without requiring full-scale complex simulations. By working with these simplified copies, the system can evaluate multiple architectural options efficiently, identifying optimal cooling strategies while keeping the selection process manageable.
