Electronic Device Partition Board Airflow Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cooling performance of electronic devices is reduced when one or more fans stop operating or are replaced, leading to a disruption in the airflow through separate ducts, which can impair the cooling of electronic parts within the housing.
Innovation Solution
An electronic device design featuring a housing with multiple fans aligned in the width direction, a partition board extending downstream in the airflow direction, and a passage resistor further downstream, which helps maintain airflow and pressure differences to ensure continuous cooling even if one fan stops or is replaced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple fans are installed to cool electronic parts, then cooling performance is improved, but device complexity increases
Solution Approach 1:
The housing is divided into multiple independent flow passages, each served by a separate fan. This segmentation allows individual fans to be removed or stopped without affecting other flow passages, maintaining cooling performance while managing device complexity through modular design
Solution Approach 2:
Partition boards are introduced as intermediary structures to separate and guide airflow between different fan regions. These partition boards ensure that when one fan is removed, airflow from other fans is redirected through the housing rather than creating dead zones, thus maintaining cooling efficiency
2Ease of repair
If a fan is removed for electronic part replacement, then ease of repair is improved, but cooling performance deteriorates
Solution Approach 1:
Each fan serves its own dedicated flow passage region, allowing individual fans to be removed for repair without impacting the functionality of other fan systems. The housing structure ensures airflow continuity through alternative paths when a fan is absent
Solution Approach 2:
The housing is pre-designed with airflow redirection capabilities and partition structures that automatically guide cooling air around removed fan regions. This preliminary design ensures that cooling performance is maintained without requiring additional components during repair operations
3Stability of the object's composition
If fans are aligned in width direction with partition boards, then airflow stability is improved, but device complexity increases
Solution Approach 1:
Partition boards are strategically placed at specific locations within the housing to create localized flow guidance. This selective placement provides airflow stability where needed while minimizing the overall number of partition structures, thus managing device complexity
Solution Approach 2:
The partition boards are designed with asymmetric configurations tailored to the specific airflow patterns generated by each fan arrangement. This asymmetric design optimizes airflow redirection efficiency while avoiding unnecessary symmetric structures that would increase complexity
