Cooling system for vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cooling systems for vehicles, particularly in electric vehicles, face challenges in reducing the thickness and front overhang due to the larger size requirements of the condenser and radiator, which inefficiencies the front compartment and stability of the vehicle.
Innovation Solution
The cooling system arranges the radiator and condenser side by side along the width or height direction of the vehicle, incorporating an auxiliary chamber for improved fluid communication and dual cooling structures, reducing the overall thickness and front overhang while enhancing condensation performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the condenser and radiator are arranged sequentially along the longitudinal direction of the vehicle, then the cooling efficiency is maintained, but the thickness of the cooling system increases
Solution Approach 1:
The patent transitions from a longitudinal arrangement (sequential along the length of the vehicle) to a lateral arrangement (side-by-side along the width of the vehicle). This dimensional change allows the cooling components to occupy less space in the longitudinal direction, thereby reducing the front overhang while maintaining cooling efficiency through optimized airflow paths and component positioning.
2Temperature
If the radiator size is increased to cool the coolant at lower temperatures for electric vehicles, then the cooling capacity is improved, but the thickness and size of the cooling system increase
Solution Approach 1:
The patent optimizes the local characteristics of the radiator and condenser by positioning them side-by-side with specific orientation arrangements. This allows each component to be sized appropriately for its function while the combined lateral arrangement prevents excessive thickness. The airflow distribution and component geometry are locally optimized to achieve high cooling capacity without increasing overall system thickness.
3Length of stationary object
If the condenser and radiator are arranged side by side along the width direction, then the thickness is reduced, but the airflow distribution and cooling performance may be affected
Solution Approach 1:
The patent segments the airflow paths and optimizes them for the side-by-side configuration. By dividing the cooling system into distinct lateral zones for the condenser and radiator, each component receives optimized airflow distribution. This segmentation allows the system to maintain high cooling performance despite the compact lateral arrangement, as each component is positioned to maximize its heat exchange efficiency.
