Battery Pack Charger Airflow Layout for Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging devices lack effective temperature control mechanisms for battery packs during charging, leading to inefficient charging times and potential damage from temperature extremes.
Innovation Solution
The integration of fans and air diverting hoods within the charging device's receiving shafts allows for active temperature control, with fans oriented along the housing's longitudinal direction and air diverting hoods guiding airflow to ensure comprehensive temperature management, including cooling and heating of battery packs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If active temperature control is implemented using fans, then temperature management capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the housing structure: the housing not only contains the battery pack but also integrates fan mounting surfaces, air diverting hood attachments, and flow guidance features. This merging approach adds temperature control functionality without proportionally increasing overall device complexity.
Solution Approach 2:
The patent introduces air diverting hoods as intermediary components that mediate between the fans and the battery pack. These hoods guide and direct airflow patterns, enabling effective temperature control while keeping the fan placement and control system relatively simple.
2Ease of manufacture
If fans are oriented in the longitudinal direction of the housing, then airflow generation is simplified, but temperature control effectiveness may be reduced
Solution Approach 1:
Air diverting hoods serve as intermediary components that take the simplified longitudinal airflow from fans and redirect/shape it into effective cooling patterns around the battery pack, maintaining manufacturing simplicity while achieving temperature control effectiveness.
Solution Approach 2:
The air diverting hoods create localized airflow patterns with specific qualities (direction, velocity, distribution) tailored to the battery pack's thermal needs, while the fans themselves maintain a simple uniform orientation throughout the housing.
