Segmented Heatsink Cooling for Multi-Component Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional heatsink systems struggle to efficiently cool multiple components in devices, such as multi-chip modules, where components have different temperature requirements, often leading to overheating and performance issues due to the need for a large and costly heatsink.
Innovation Solution
A 'double-decker' heatsink system with multiple heatsinks, each secured to a base and physically separated to prevent thermal crosstalk, allowing independent cooling of components to operate at their specific threshold temperatures, using separate spring systems for proper contact and minimizing heat transfer between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single large heatsink is used to cool multiple components with different temperature requirements, then the cooling capacity is sufficient for the most sensitive component, but the heatsink size and cost become prohibitively large
Solution Approach 1:
The patent divides a single large heatsink into multiple smaller, independent heatsinks (first heatsink, second heatsink, etc.), each dedicated to cooling a specific component. This segmentation allows each heatsink to be sized appropriately for its component's cooling needs rather than oversizing all heatsinks to meet the most sensitive component's requirements.
Solution Approach 2:
The patent applies different cooling solutions (different heatsink sizes, configurations, or types) to different components based on their specific thermal requirements. Each component receives a customized cooling approach matched to its power dissipation and temperature thresholds, optimizing overall system thermal management.
2Temperature
If a single large heatsink is used to cool multiple components with different temperature requirements, then the cooling capacity is sufficient for the most sensitive component, but the cost becomes prohibitively expensive
Solution Approach 1:
By segmenting the heatsink system into multiple smaller units, the patent reduces the total material cost compared to using one large heatsink. Each smaller heatsink requires less thermal management material, and the modular approach allows for more efficient manufacturing and assembly.
Solution Approach 2:
The patent employs multiple smaller, potentially less expensive heatsink units rather than one large, costly heatsink. This approach trades the high cost of a single large thermal management component for multiple smaller, more cost-effective units that can be individually optimized.
3Reliability
If components are cooled to the lowest temperature threshold, then all components operate within safe temperatures, but the cooling efficiency decreases due to thermal crosstalk
Solution Approach 1:
The patent physically separates heatsinks and introduces thermal isolation barriers between them, preventing thermal crosstalk. This segmentation allows each heatsink to independently manage its component's heat without being affected by adjacent heatsinks, improving overall cooling efficiency.
Solution Approach 2:
The patent introduces thermal isolation barriers (intermediary structures) between adjacent heatsinks to prevent unwanted heat transfer. These barriers act as mediators that block thermal crosstalk while allowing each heatsink to maintain its component at the appropriate temperature.
4Temperature
If multiple independent heatsinks are used for each component, then each component can be cooled to its optimal temperature, but the device complexity increases
Solution Approach 1:
The patent employs a universal base structure that supports multiple different types of heatsinks. This multi-functional base can accommodate various heatsink configurations, sizes, and attachment methods, allowing the system to handle different thermal requirements without requiring fundamentally different support structures for each component.
