Liquid Cooling Device Flow-Rate Adjustment Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid cooling systems for integrated circuits, such as multi-core processors, do not optimize coolant flow rates effectively, leading to inefficient cooling of high-temperature areas as the same coolant flow rate is supplied to both high and low heat-generating regions, resulting in suboptimal cooling capacity.
Innovation Solution
A liquid cooling device with a flow-rate adjustment component that includes a covering portion and blocking portions to create different flow rates among passageways, allowing for increased coolant flow to high heat-generating areas by blocking passageways over low heat-generating areas, thereby optimizing coolant distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same coolant flow rate is supplied to both high heat-generating areas and low heat-generating areas, then the cooling system is simple to operate, but the cooling efficiency of high heat-generating areas is insufficient
Solution Approach 1:
The patent applies local quality by creating different flow rate conditions in different regions of the cooling device. The flow rate adjustment component is positioned to selectively increase coolant flow through passageways located at high heat-generating areas while maintaining normal flow through passageways at low heat-generating areas. This localized flow rate differentiation directly addresses the cooling efficiency problem without complicating overall system operation.
2Temperature
If blocking portions are added to create different flow rates in different passageways, then the cooling efficiency of high heat-generating areas is improved, but the device complexity increases
Solution Approach 1:
The flow rate adjustment component serves as an intermediary element that mediates between the coolant supply and the passageways. This single intermediate component performs the function of differentiating flow rates across multiple passageways through its blocking portions, avoiding the need for separate control mechanisms for each passageway. The intermediary approach achieves the desired flow differentiation while minimizing the increase in device complexity.
Solution Approach 2:
The patent changes the flow rate parameter selectively in different regions by using blocking portions that physically obstruct certain passageways. This parameter change approach allows the system to maintain high flow rates at high heat-generating areas while reducing flow rates at low heat-generating areas. The parameter change is achieved through a simple structural modification rather than complex control systems.
