Cooling Block Assembly for Easy Heatsink Unmounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling system block assemblies face difficulties in horizontal movement during unmounting due to increased adhesive force, leading to potential damage and inefficiency in separating the heatsink or cooling system block from the packaged integrated circuit.
Innovation Solution
A cooling system block assembly design that includes rotatably disposable and vertically movable attachment members, allowing for vertical alignment during mounting and horizontal movement during unmounting, with a configuration of positioning members and counterbores that adjust compression forces for secure fixing and easy separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If positioning members are fixed to the cooling system block for vertical alignment during mounting, then alignment precision is improved, but ease of unmounting deteriorates due to increased adhesive force preventing horizontal movement
Solution Approach 1:
The positioning members are segmented into two functional parts: a first portion that remains fixed to the cooling system block for alignment, and a second portion that can be separated from the circuit board during unmounting. This segmentation allows the alignment function to be retained while eliminating the constraint that prevents easy unmounting.
Solution Approach 2:
The positioning members transition from a static fixed configuration during mounting to a dynamic separable configuration during unmounting. The first portion remains stationary on the cooling system block while the second portion can be detached from the circuit board, enabling horizontal movement for easy unmounting after vertical alignment is achieved.
2Reliability
If attachment members are fixed securely to maintain stable attachment during operation, then reliability is improved, but ease of unmounting deteriorates due to increased adhesive force
Solution Approach 1:
The attachment members are divided into a first portion fixed to the cooling system block and a second portion that can be separated from the circuit board. This segmentation maintains secure attachment during operation through the first portion while enabling easy unmounting by separating the second portion.
Solution Approach 2:
The attachment members exhibit dynamic behavior where they remain fixed and stable during operational phases for reliable attachment, but can be separated into two portions during unmounting phases. The first portion stays on the cooling system block while the second portion detaches from the circuit board.
3Ease of operation
If positioning members are separately unfixed from the cooling system block and circuit board, then ease of unmounting is improved, but device complexity increases due to additional steps and potential lost parts
Solution Approach 1:
The positioning members are pre-segmented into a first portion attached to the cooling system block and a second portion attached to the circuit board. This pre-segmentation simplifies the unmounting process by eliminating the need to separately unfix positioning members from both components, as the second portion is already detached and can be easily removed without risking lost parts.

AI summary
A cooling system block assembly may include a cooling system block and a circuit board assembly. The cooling system block includes a plurality of attachment members and one or more positioning members. The circuit board assembly is fixed to the cooling system block via the plurality of attachment members. The circuit board assembly includes a socket and a plate. The socket includes one or more positioning hubs and the plate includes a plurality of attachment hubs. The one or more positioning members is disposed within the one or more positioning hubs and the plurality of attachment members is fixed within the plurality of attachment hubs. When the one or more positioning members is disposed within the one or more positioning hubs and the plurality of attachment members is not fixed within the plurality of attachment hubs, the plurality of attachment members is vertically aligned with the plurality of attachment hubs.
