Underbody Cooling Module With Tangential Fan for Grille-Free EV Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles without traditional grilles or cooling bays face challenges in maintaining effective airflow through the cooling module, leading to reduced performance.
Innovation Solution
A cooling module design featuring a fairing with an internal duct and tangential turbomachine, along with a collector housing and heat exchangers, ensures airflow circulation without a grille, using fixing means to secure the module to the vehicle chassis and adjustable closure devices to regulate airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle is equipped with traditional grilles and cooling bays, then airflow to the cooling module is improved, but aerodynamic characteristics and vehicle range deteriorate
Solution Approach 1:
The cooling module is repositioned from the traditional front grille location to the underbody of the vehicle, changing the spatial dimension of air intake. This allows the vehicle to maintain cooling functionality while eliminating the need for front grilles, thereby improving aerodynamics and reducing energy loss without compromising cooling performance
2Reliability
If the vehicle operates at stationary or low driving speed, then natural airflow through the cooling module is insufficient, but adding a tangential turbomachine increases device complexity
Solution Approach 1:
The tangential turbomachine is designed to be driven by the vehicle's own exhaust gases, which naturally flow through the turbocharger during engine operation. This self-service mechanism eliminates the need for an external power source or complex control systems, providing reliable cooling enhancement while maintaining relatively simple device architecture
