Electronic Component Package Flow Path Guide Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component packages, such as DC-to-DC converters in hybrid vehicles, face inefficiencies in cooling due to the generation of eddies and bubbles in the cooling water flow, which lowers cooling performance.
Innovation Solution
The package includes a housing with a flow path featuring a first region connected to an inlet and a second region connected to an outlet, where the first region has a tapered portion that becomes bent, and a guide with varying width to control the flow speed and rate, reducing eddies and bubbles by dividing the cooling water flow uniformly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling water is circulated at high pressure to improve cooling efficiency, then cooling performance is enhanced, but eddies and bubbles are generated which lowers cooling efficiency
Solution Approach 1:
The flow path is divided into multiple regions (first region with inlet, second region with outlet, and intermediate regions) with different structural characteristics. Each region has specific tapered portions and guides that segment the cooling water flow into controlled streams, preventing chaotic eddies while maintaining high-pressure cooling efficiency
Solution Approach 2:
Different portions of the flow path have different geometric properties - the first region has a first tapered portion with specific curvature, the second region has a second tapered portion, and guides with varying widths are placed at specific locations. These local structural variations optimize flow characteristics at each location to eliminate eddies and bubbles while maintaining overall cooling performance
2Temperature
If cooling water flows uniformly to improve cooling performance, then heat dissipation is enhanced, but flow uniformity is difficult to achieve without creating eddies
Solution Approach 1:
The first tapered portion in the first region preliminarily conditions the cooling water flow before it enters the main flow path. This preliminary tapering action smooths the flow and prevents eddy formation at the inlet, establishing uniform flow conditions that are maintained throughout the subsequent flow path
Solution Approach 2:
Guides with varying widths act as intermediary structures between different flow regions. These guides mediate the transition of cooling water between regions, controlling flow distribution and maintaining uniformity while preventing the formation of eddies and bubbles that would disrupt stable flow
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances cooling efficiency by controlling the flow of cooling water, reducing eddies and bubbles, thereby improving the thermal management of electronic components.
Implementation Method 1
the first region includes a guide, and the guide includes a region of which a width increases as a distance from the inlet to the guide increases
Implementation Method 2
the first tapered portion become bent so that a distance from the second region to the first tapered portion increases
