Wind Flux Concentration Guiding Device for Engine Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cooling systems in vehicles, particularly diesel and gasoline turbo engines, face limitations in increasing the inflow of wind to intercoolers due to design restrictions, which hampers the cooling performance and efficiency of the engine, as the front end area is crucial for both cooling and external appearance.
Innovation Solution
A wind flux concentration guiding device that directs wind from the radiator grill and bumper portions to both the intercooler and air intake, utilizing a main duct, sub-duct, and diverging duct to optimize the flow and increase the inflow of wind without altering the intercooler's specifications, thereby enhancing cooling performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the front end open area is increased to supply more wind to the condenser, radiator, and intercooler, then cooling performance is improved, but the external appearance design freedom is restricted
Solution Approach 1:
The wind guiding device divides the front end wind flow into multiple segments: wind passing through the radiator grill is directed to the intercooler and air intake, while wind from the bumper portion is directed to the air intake. This segmentation allows effective use of limited front end opening area to cool multiple components simultaneously.
Solution Approach 2:
The wind flux concentration guiding device acts as an intermediary structure that captures and redirects wind flow from the front end opening to the intercooler and air intake. It mediates between the limited front end opening area and the cooling requirements of the engine room components.
2Temperature
If the intercooler specifications are upgraded to improve cooling performance, then engine efficiency is improved, but the cost and complexity increase
Solution Approach 1:
The intercooler is designed to utilize natural wind flow from the front end opening without requiring active cooling systems or complex specifications. The wind flux concentration guiding device directs ambient wind to the intercooler, allowing it to self-cool using environmental resources.
3Shape
If the front end open area is restricted for external appearance, then design freedom is maintained, but the inflow amount of wind to the intercooler is limited
Solution Approach 1:
The wind guiding device utilizes the vertical dimension by positioning the intercooler above the bumper portion and directing wind from both the radiator grill (upper region) and bumper portion (lower region). This multi-level wind capture approach maximizes wind inflow within the constrained front end opening area.

Implementation Method 1
wind passing through a radiator grill disposed at the top of a front end part forming a front portion of an engine room may be introduced and configured to be discharged to two different parts of an intake system
Implementation Method 2
wind flowing to a bumper portion disposed at the bottom of the front end part may be introduced and configured to be discharged to any one of the two different parts
Implementation Method 3
an intercooler that cools oversupplied air from a turbocharger
Implementation Method 4
cooling performance of wind flowing into the engine room when the vehicles travel

AI summary
An engine room layout using a wind flux concentration guiding device, may include an intake system having an air intake, a turbocharger, and an intercooler, and may be disposed in an engine room, a cooling module having a condenser and a radiator, a main duct that introduces wind passing through a front end part forming the front of the engine room and discharges the wind to the air intake and the intercooler, a sub-duct that introduces the wind passing through the front end part from different positions and discharges the wind to the intercooler, and a diverging duct that may be connected to a wind channel of the main duct to diverge some of the wind introduced into the main duct before the wind passes out of the main duct, and send the wind to the air intake.
