Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design of vehicle front ends restricts the increase in radiator grill and bumper cover holes to improve cooling performance, leading to decreased engine cooling and increased fuel consumption, while also compromising the vehicle's design aesthetics.
Innovation Solution
A dual air duct system that includes an upper duct guiding wind through the radiator grill to the intercooler's upper portion and a lower duct guiding wind through the bumper cover holes to the intercooler's lower portion, with blocking plates to direct airflow effectively, enhancing cooling performance without altering the vehicle's design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the areas of radiator grill or bumper cover holes are increased to improve cooling performance, then cooling performance of heat sinks is improved, but design aesthetics of vehicle front appearance is compromised
Solution Approach 1:
The invention divides the air duct system into multiple segments: upper duct for guiding air to upper intercooler, lower duct for guiding air to lower intercooler, and blocking plates to direct airflow. This segmentation allows efficient cooling airflow distribution without requiring large external openings, thus maintaining design aesthetics while improving cooling performance
Solution Approach 2:
The invention utilizes the vertical dimension by creating upper and lower ducts that guide airflow to different heights of the intercooler. This three-dimensional airflow distribution maximizes cooling efficiency within the available space without increasing the horizontal area of external openings, resolving the conflict between cooling performance and appearance design
2Power
If the areas of radiator grill or bumper cover holes are increased to improve cooling performance, then engine power is increased and fuel consumption is decreased, but design aesthetics of vehicle front appearance is compromised
Solution Approach 1:
The air duct system is segmented into upper and lower ducts with blocking plates to optimize airflow distribution to the intercooler. This improves charging efficiency and engine power without requiring larger external openings, thus maintaining design aesthetics
Solution Approach 2:
The invention changes the airflow parameters by creating directed airflow paths through the ducts and blocking plates, improving air-to-intercooler contact efficiency. This enhances cooling performance and engine power without increasing the physical area of external openings
3Temperature
If ducts are added to guide airflow to intercooler, then cooling performance of intercooler is improved, but device complexity increases
Solution Approach 1:
The upper and lower ducts serve multiple functions: guiding airflow from different sources (radiator grill and bumper cover holes) to different portions of the intercooler, and the blocking plates simultaneously block gaps and direct airflow. This multi-functionality improves intercooler cooling without proportionally increasing structural complexity
