Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Future generations of processor-based electronic devices face cooling challenges that conventional packaging solutions and convective cooling methods are unable to fully address, particularly when these devices need to be accessed by users for comfort and safety, as they generate higher surface temperatures during operation.
Innovation Solution
A heat exchanging system and method that utilizes a movable heat sink integrated into a dock, which contacts a thermally conductive member of the electronic device during an ejection cycle to conductively cool it, ensuring the surface temperature is reduced below a safe threshold before user access, thereby allowing the use of processors with higher maximum junction temperatures for increased processing speed while maintaining user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If processors with higher maximum junction temperatures are used to increase processing speed, then productivity is improved, but the external surface temperature becomes unsafe for user handling
Solution Approach 1:
The system performs preliminary cooling action during the ejection cycle by deploying the heat sink to contact the thermally conductive member before the device is fully ejected, reducing surface temperature to safe levels before user handling occurs
Solution Approach 2:
A movable heat sink acts as an intermediary thermal management component between the high-power processor and the external environment, transferring heat during the ejection cycle to reduce surface temperature without affecting processor operation
2Temperature
If convective cooling methods are used to dissipate heat, then temperature is reduced, but the cooling effectiveness is insufficient for high-power processors
Solution Approach 1:
The system replaces insufficient convective cooling with a mechanical thermal conduction system, where a movable heat sink physically contacts the device to directly conduct heat away during the ejection cycle, providing more effective cooling for high-power processors
3Object-affected harmful factors
If a movable heat sink is deployed during the ejection cycle, then surface temperature is reduced to safe levels, but device complexity increases
Solution Approach 1:
The movable heat sink is integrated into the dock structure and serves multiple functions: it provides thermal management during the ejection cycle, structural support for the device, and can be part of the mechanical ejection mechanism itself, reducing overall system complexity despite the added cooling capability
