Socket Cooler Fixing Structure for Main Board Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing sockets for testing main boards do not have a separate structure to easily install and securely attach water-cooled coolers to the top surface of CPUs, leading to difficulties in testing and inefficient heat dissipation during the process.
Innovation Solution
A socket with a water-cooled cooler fixing structure that includes a socket body with a cooler positioning recess, a cooler fixing unit using a hinge mechanism, and a cooler pressing unit to resiliently attach and press the water-cooled cooler onto the CPU, along with a socket fixing unit to secure the socket to the main board, ensuring a strong attachment force and efficient cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a water-cooled cooler is fixed to the CPU using only heat transferring grease and a clip without a separate fixing structure, then the attachment is simple, but the attachment force is insufficient and testing becomes difficult
Solution Approach 1:
The fixing socket is divided into distinct functional components: a socket body with a cooler positioning recess, a separate cooler fixing unit with hinge mechanism, and a cooler pressing unit. This segmentation allows each component to perform its specific function effectively while maintaining overall system reliability.
Solution Approach 2:
The cooler fixing unit employs a hinge mechanism that enables dynamic adjustment and secure locking of the water-cooled cooler to the CPU. The hinge allows the fixing unit to move between open and closed positions, providing both ease of installation and reliable attachment through mechanical engagement.
2Temperature
If a large-volume air-cooled cooler is installed on the CPU, then cooling is provided, but the socket volume becomes large and testing becomes inconvenient
Solution Approach 1:
The patent employs a water-cooled cooler that uses hydraulic cooling (water circulation) instead of air cooling. This allows for a more compact design with higher cooling efficiency, as water has better heat capacity and thermal conductivity compared to air, enabling effective cooling in a smaller volume.
3Temperature
If a water-cooled cooler is used instead of an air-cooled cooler, then cooling efficiency improves and volume decreases, but the fixing structure becomes more complex
Solution Approach 1:
The cooler fixing unit serves multiple functions: it positions the water-cooled cooler, secures it through hinge mechanism, and maintains contact pressure via the pressing unit. This multi-functionality consolidates several operations into a single integrated structure, reducing overall system complexity despite the advanced cooling technology used.
4Ease of manufacture
If heat transferring grease is used to fix the water-cooled cooler, then attachment is achieved, but thermal contact and cooling efficiency are insufficient
Solution Approach 1:
The cooler pressing unit is designed to apply preliminary and continuous pressure to the water-cooled cooler, ensuring optimal thermal contact between the cooler and CPU before and during operation. This preliminary action of pressing complements the heat transferring grease by maintaining consistent physical contact, thereby maximizing heat transfer efficiency.
