Solution Overview

Problem

Current synthetic jet ejectors are difficult and costly to manufacture, and lack adequate safeguards for proper assembly, which hinders their efficiency and reliability in thermal management for semiconductor devices and electronic equipment.

Innovation Solution

A moldable housing design for synthetic jet ejectors is developed, allowing for the use of a small number of housing components that can be easily fabricated using common molding techniques, integrating nozzles and actuator mountings, and ensuring proper assembly through keying features and adhesives or seals to form a complete synthetic jet ejector or thermal management unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional synthetic jet ejector designs are used, then thermal management performance is achieved, but manufacturing complexity and cost increase

Engineering Contradiction:

Improvethermal management performanceVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The housing is divided into multiple portions that can be separately molded and then assembled. This segmentation allows each portion to be manufactured using simple, cost-effective molding processes while maintaining the overall thermal management functionality of the synthetic jet ejector

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple housing portions are joined together to form the complete housing structure. This merging approach enables complex geometries to be achieved through assembly of simpler components, reducing individual manufacturing difficulty while preserving thermal performance

Inventive Principle:

Principle #5Merging (Combining)
