Vehicle Cooling Mechanism Vertical Radiator Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with multiple radiators, achieving efficient cooling while considering the positional relationship and opening portion of the front end is challenging, as existing configurations do not effectively prioritize the cooling needs of each radiator.
Innovation Solution
A vehicle cooling mechanism is designed with a first radiator for the battery and a second radiator for the power conversion device, where the second radiator overlaps the opening portion and has a higher cooling capacity, with an air guide duct system that directs outside air to both radiators, ensuring effective cooling without obstructing airflow and protecting against foreign matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple radiators are arranged in the front room, then the cooling capacity for multiple components is improved, but the positional relationship with the opening portion becomes complex and cooling efficiency deteriorates
Solution Approach 1:
The patent transitions from horizontal arrangement to vertical arrangement of radiators, utilizing the height dimension. The first radiator is positioned above the second radiator, both overlapping the opening portion vertically, which simplifies the positional relationship while maintaining multiple cooling zones.
Solution Approach 2:
Each radiator is given a specific vertical position relative to the opening portion, with the first radiator above and the second radiator below. This local differentiation allows each radiator to serve its specific cooling function while the overall arrangement remains simple and systematic.
2Power
If the second radiator is arranged to overlap the opening portion, then the cooling capacity of the second radiator is improved, but the risk of foreign matter damage increases
Solution Approach 1:
The cooling system is segmented into two distinct radiators positioned at different vertical levels. The first radiator is positioned higher to be protected from foreign matter, while the second radiator is positioned lower to maximize cooling capacity, dividing the functions of protection and high-performance cooling.
Solution Approach 2:
The first radiator acts as an intermediary protective element positioned above the second radiator. It can serve as a physical barrier or guide structure that protects the second radiator from foreign matter while still allowing airflow to reach it for effective cooling.

AI summary
A vehicle cooling mechanism includes a first radiator configured to cool a battery of a vehicle, a second radiator configured to cool a power conversion device that converts electric power supplied from the battery and electric power supplied to the battery, and an air guide duct portion configured to guide outside air from an opening portion provided in a front end portion of the vehicle to the first radiator and the second radiator. The first radiator is arranged above the second radiator. At least a part of the second radiator is arranged so as to overlap the opening portion as viewed from a front side of the vehicle. An upper end portion of the second radiator is positioned above an upper end portion of the opening portion. A lower end portion of the second radiator is positioned below the upper end portion of the opening portion.
