Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of motherboard testing is increased due to the repeated assembly and disassembly required when using cold plates and heat sinks alternately with boiler plates for immersion and air-based tests, leading to coolant loss.
Innovation Solution
A heat dissipation assembly and motherboard module that includes a heat exchange plate with a boiling enhancement structure, allowing for a fluid chamber formation with a cover, and enabling both cold plate and boiler plate modes without removing the heat exchange plate from the heat source, by using removable joints and vortex-guided coolant flow to minimize pressure drop and bubble accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If cold plate or heat sink is used for air environment testing, then coolant loss is reduced, but test complexity increases due to repeated assembly and disassembly
Solution Approach 1:
The heat dissipation assembly is designed to serve multiple functions: it can operate as a cold plate for air environment testing and as a boiler plate for immersion coolant testing. The heat exchange plate with integrated coupling surfaces allows the same component to replace both cold plates/heat sinks and traditional boiler plates, eliminating the need for separate components and reducing test complexity while preventing coolant loss
Solution Approach 2:
The invention merges the functionality of cold plates, heat sinks, and boiler plates into a single heat dissipation assembly. The heat exchange plate integrates heat absorption surfaces, heat dissipation surfaces, and coupling surfaces in one component, allowing seamless switching between different testing modes without requiring multiple separate assemblies
2Temperature
If boiler plate is used for immersion testing, then heat exchange efficiency is improved, but coolant loss occurs during frequent suction for testing
Solution Approach 1:
The heat dissipation assembly can function as both a cold plate for air testing and a boiler plate for immersion testing. By integrating the coupling surfaces directly into the heat exchange plate, the design allows the same component to maintain thermal coupling with the heat source while enabling seamless switching between testing modes, thereby preventing coolant loss during frequent suction operations
3Temperature
If heat dissipation assembly is designed for immersion mode, then heat exchange efficiency is improved, but complexity increases due to removable joints and fluid chamber requirements
Solution Approach 1:
The invention combines the heat exchange plate, coupling surfaces, and fluid chamber into a single integrated assembly. The heat exchange plate includes integrated coupling surfaces that directly connect to the heat source, eliminating the need for separate coupling components. The fluid chamber is formed within the same structure, allowing the assembly to function as both cold plate and boiler plate without requiring multiple separate components
Solution Approach 2:
The heat dissipation assembly is designed to perform multiple functions through a single integrated structure. The same heat exchange plate with coupling surfaces can operate in air environment mode (as cold plate) and immersion mode (as boiler plate), reducing the need for multiple specialized components and simplifying the overall assembly
