Electronic Component Cooler With Flow Path Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component coolers do not effectively improve the velocity distribution in the refrigerant introduction flow path, which limits their cooling efficiency.
Innovation Solution
The cooler design includes protruding portions within the refrigerant introduction flow path and pipe, which constrict the flow area, creating a higher velocity distribution that enhances cooling efficiency by increasing the refrigerant's velocity as it approaches the cooling fins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the refrigerant flow path area is increased to improve refrigerant flow, then the cooling coverage is improved, but the refrigerant velocity decreases reducing cooling efficiency
Solution Approach 1:
The patent applies local quality by creating a protruding portion at a specific location within the refrigerant flow path. This protruding portion locally reduces the flow path area only in the introduction region, while maintaining a larger overall flow path area. This localized area reduction increases refrigerant velocity where needed (near the cooling fins) without sacrificing the overall cooling coverage provided by the larger flow path area.
2Speed
If the refrigerant flow path area is constricted to increase refrigerant velocity, then cooling efficiency is improved, but the refrigerant flow rate decreases reducing cooling coverage
Solution Approach 1:
The protruding portion creates a localized constriction only in the refrigerant introduction region, not throughout the entire flow path. This allows velocity increase in the critical cooling zone while maintaining adequate flow rate overall. The constriction is spatially limited rather than applying to the entire flow path, preserving the balance between velocity and flow rate.
Solution Approach 2:
The patent introduces a dimensional variation in the flow path cross-section by adding the protruding portion. This creates a three-dimensional flow path geometry where the area varies along the flow direction, allowing velocity enhancement in specific regions without uniformly reducing the flow rate throughout the entire system.
