Battery Cooling Air Intake Grille With Obstruction-Bypass Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air intake systems for battery cooling in electric vehicles are susceptible to obstruction, leading to insufficient cooling airflow and potential battery performance degradation due to increased temperature when obstructed by items like paper or magazines.
Innovation Solution
An intake duct design featuring a grille with protrusions that direct airflow vertically and incorporate a reservoir to manage pressure fluctuations, ensuring a continuous airflow path even with obstructions, thereby maintaining effective cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intake holes are provided at positions adjacent to the battery unit for cooling, then cooling airflow can be supplied to the battery unit, but the cooling airflow becomes insufficient when the intake holes are obstructed by objects such as paper or magazines
Solution Approach 1:
The patent introduces a protrusion that extends from the intake grille toward the passenger compartment, creating a three-dimensional structure that redirects airflow from a horizontal path to a vertical path. This dimensional change allows air to flow over the top of obstructions rather than being blocked by them, resolving the contradiction between maintaining cooling airflow and preventing obstruction by objects like paper or magazines
2Reliability
If a protrusion is added to redirect airflow vertically, then obstruction by objects is prevented, but the device complexity increases
Solution Approach 1:
The protrusion is integrated directly into the intake grille structure, merging the flow redirection function with the existing grille components. This integration approach adds the necessary three-dimensional flow control capability while minimizing the increase in device complexity, as the protrusion becomes part of the grille assembly rather than a separate component

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures sufficient cooling airflow to the battery unit, preventing temperature rise and maintaining battery performance even with obstructions, thus extending service life and preventing performance decline.
Implementation Method 1
a protrusion that protrudes from the intake grille towards the passenger compartment

AI summary
An air intake duct is configured to suitably supply air inside a passenger compartment of a vehicle as a cooling air to a battery unit mounted below a floor carpet in the vehicle. The air intake duct includes an intake grille and a protrusion. The intake grille has a plurality of intake holes. The intake grille is disposed in a horizontal direction at substantially a same height as the floor carpet. The protrusion protrudes from the intake grille toward the passenger compartment.
