Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coolers for electronic components face challenges in achieving uniform heat distribution due to inhomogeneous heat generation and fluid flow distribution, leading to inadequate cooling in areas with high heat concentrations and inefficient coolant usage.
Innovation Solution
The cooler features two types of channels with different geometries and flow resistances, allowing tailored coolant flow to match heat generation needs, with channels of one type placed near high heat sources and the other type placed where more cooling is required, ensuring efficient heat removal while maintaining fluid flow through all channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If uniform channels are used throughout the cooler, then manufacturing is simple, but cooling effectiveness is insufficient in high heat concentration areas
Solution Approach 1:
The patent applies local quality by implementing different channel geometries in different regions of the cooler base plate. Specifically, channels in high heat concentration areas have different dimensions or configurations compared to channels in low heat concentration areas, allowing each region to receive appropriate cooling capacity matched to its thermal load requirements.
2Temperature
If coolant flow is increased to improve cooling, then heat removal improves, but coolant distribution becomes inhomogeneous
Solution Approach 1:
The patent uses local quality by varying channel geometries to create regions with different flow resistance characteristics. Channels in high heat concentration areas are designed to receive higher coolant flow rates, while channels in low heat concentration areas receive lower flow rates, achieving homogeneous cooling effectiveness across all regions despite non-uniform coolant distribution.
3Temperature
If channels are placed closer to coolant feed for better cooling, then cooling effectiveness improves near feed, but channels farther away receive insufficient cooling
Solution Approach 1:
The patent applies local quality by designing channels at different distances from the coolant feed with appropriately differentiated geometries. Channels closer to the feed have geometries optimized for their position, while channels farther away have geometries that compensate for the reduced coolant pressure and flow, ensuring all channels contribute effectively to cooling across the entire base plate area.
4Quantity of substance
If channel geometry is optimized for high flow, then coolant delivery improves, but flow control precision decreases
Solution Approach 1:
The patent applies segmentation by dividing the cooler into multiple independent channel regions, each with its own optimized geometry. This segmentation allows each channel or channel group to be independently designed and manufactured with precise geometric features that control flow distribution, while the overall system achieves both high coolant delivery and precise flow control through the cumulative effect of multiple segmented channels.
