Angled Multi-Fan Radiator Assembly for Compact Cooling Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy-duty equipment radiators face inefficiencies in airflow and increased power requirements when fans are moved closer to the radiator to achieve a compact configuration, leading to reduced cooling performance.
Innovation Solution
The radiator assembly features multiple fans angled with respect to the radiator's front surface, with each fan's rotation axis extending outwardly and rearwardly, allowing for a compact design while minimizing airflow restrictions and reducing power consumption by optimizing airflow through the radiator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If fans are moved closer to the radiator to achieve a compact configuration, then the radiator assembly becomes more compact and fits better within the vehicle, but airflow efficiency decreases and power requirements increase
Solution Approach 1:
The fan rotation axes are oriented at an acute angle (e.g., 30 degrees) relative to the radiator plane, rather than being perpendicular to it. This angular orientation allows the fans to be positioned closer to the radiator in the longitudinal direction while maintaining adequate airflow clearance, effectively utilizing three-dimensional space to resolve the contradiction between compactness and airflow efficiency
Solution Approach 2:
The angled fan configuration creates a dynamic airflow pattern that directs air at an angle across the radiator core. This dynamic approach optimizes the airflow path length and distribution across the radiator surface, improving cooling efficiency while allowing closer fan placement
2Volume of moving object
If fans are moved closer to the radiator to achieve a compact configuration, then the radiator assembly becomes more compact and fits better within the vehicle, but airflow efficiency decreases
Solution Approach 1:
By orienting fan rotation axes at an acute angle to the radiator plane rather than perpendicular to it, the design utilizes angular positioning to maintain effective airflow clearance while reducing the longitudinal distance between fans and radiator, achieving compactness without sacrificing airflow efficiency
Solution Approach 2:
The angled fan configuration creates localized optimal airflow patterns across different regions of the radiator core. Each fan's angled position is specifically optimized to direct airflow efficiently across its corresponding portion of the radiator surface, maintaining high airflow efficiency in a compact arrangement

AI summary
A radiator assembly includes a frame and a radiator mounted to the frame proximate a front of frame and defining a radiator plane extending along a front surface of the radiator. Each of a plurality of fans is mounted to the frame rearwardly of the radiator, with each fan defining a fan rotation axis that extends outwardly and rearwardly away from the frame.
