Liquid Immersion Tank Flow Adjusting Plate for Cooling Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid immersion tanks face challenges in uniformly distributing coolant flow among electronic units with varying packing densities, leading to inadequate cooling for high-packing density units and potential overcooling of low-packing density units.
Innovation Solution
The design incorporates a movable flow adjusting plate system with aligned flow adjusting holes and straightening holes, allowing for adjustable coolant flow based on the type of electronic unit, with the flow adjusting holes' total opening area being smaller than the straightening holes' area, and utilizing push-down members to position the plates appropriately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a straightening plate with straightening holes is used to distribute coolant, then coolant flow is provided to electronic units, but uniform distribution of coolant flow among electronic units with varying packing densities is difficult, leading to inadequate cooling for high-packing density units and potential overcooling of low-packing density units
Solution Approach 1:
The patent applies local quality by providing different total opening areas for flow adjusting holes in different regions of the flow adjusting plate. Specifically, the flow adjusting plate has a first region with a first total opening area and a second region with a second total opening area, where the areas differ to match the varying cooling demands of electronic units with different packing densities. This allows each region to deliver appropriate coolant flow locally, resolving the contradiction between achieving uniform distribution and accommodating varying cooling requirements.
2Ease of operation
If the total opening area of flow adjusting holes is made smaller than straightening holes, then coolant flow is restricted to prevent overcooling, but this may lead to inadequate cooling for high-packing density electronic units
Solution Approach 1:
The patent resolves this contradiction by dividing the flow adjusting plate into multiple regions with different total opening areas. The first region has a larger first total opening area to provide adequate cooling for high-packing density electronic units, while the second region has a smaller second total opening area to prevent overcooling of low-packing density units. This local differentiation allows the system to simultaneously satisfy both cooling adequacy and flow control requirements.
3Device complexity
If a fixed plate structure is used, then the structure is simple, but the coolant flow cannot be adjusted according to different electronic unit types
Solution Approach 1:
The patent applies dynamics by making the flow adjusting plate movable relative to the straightening plate. The flow adjusting plate can be positioned at different locations along the flow direction, allowing the system to adjust coolant flow distribution according to different electronic unit types and cooling requirements. This dynamic adjustability is achieved through a simple structure that includes positioning mechanisms, resolving the contradiction between structural simplicity and flow adaptability.
