Flow Guiding Cover Assembly for Battery Pack Cooling Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery formation equipment experiences poor heat dissipation for battery sets due to cooling airflow passing through charge and discharge sets first, which increases the temperature of the airflow before it reaches the battery sets.
Innovation Solution
A flow guiding cover assembly is introduced, featuring an air intake cover and air outlet covers, which directs cooling airflow from an air conditioning device directly to the top portion of battery packs, bypassing the charge and discharge sets to enhance heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling airflow passes through charge and discharge sets first, then the cooling airflow can cool the charge and discharge sets, but the temperature of the cooling airflow increases before reaching the battery sets, leading to poor heat dissipation for the battery sets
Solution Approach 1:
The flow guiding cover assembly segments the cooling airflow path by introducing separate air intake covers and air outlet covers. The air intake cover receives cooling airflow from the air conditioning device, and the air outlet cover directs this cooled airflow specifically to the battery pack, preventing the airflow from passing through the charge and discharge sets first. This segmentation ensures that the battery pack receives cooler airflow for better heat dissipation.
Solution Approach 2:
The flow guiding cover assembly acts as an intermediary component between the air conditioning device and the battery pack. It includes an air intake cover adapted to be disposed at one side of the air conditioning device and an air outlet cover that directs the cooling airflow to the battery pack, thereby mediating the airflow path to avoid direct contact with the charge and discharge sets while still achieving effective cooling.
2Reliability
If cooling airflow is directed directly to battery packs bypassing charge and discharge sets, then heat dissipation for battery packs is improved, but the charge and discharge sets may experience overheating
Solution Approach 1:
The flow guiding cover assembly implements local quality by providing different airflow paths for different components. The air outlet cover is specifically configured to direct cooling airflow to the battery pack location, while the charge and discharge sets have their own cooling arrangement through the cabinet's overall ventilation system. This localized cooling approach ensures that each component receives appropriate cooling based on its specific thermal requirements.
