Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiators are bulky, noisy, and energy-inefficient due to bulky fans, suboptimal thermal efficiency, and ineffective side air outlets, which also pose maintenance challenges.
Innovation Solution
The radiator features low-voltage DC fans arranged helicoidally along the front wall, dual exchanger modules with longitudinal air inlets, and a thermally inertial plate for improved air distribution and diffusion, reducing thickness and energy consumption while using water as a heat transfer fluid for environmental benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If bulky fans powered by alternating current are used, then ventilation capability is sufficient, but the radiator thickness increases, noise level increases, and energy consumption increases
Solution Approach 1:
The single bulky fan is segmented into multiple small-diameter helicoidal fans (5-10 fans) arranged in a row. Each fan handles a portion of the air flow, collectively achieving the required ventilation capability while each individual fan has reduced dimensions, thereby reducing overall radiator thickness.
Solution Approach 2:
The alternating current motor system is replaced with a low-voltage direct current (12-24V or 48V) electrical system. This substitution reduces energy consumption by approximately half and enables the use of smaller, quieter fan motors with lower mechanical inertia, reducing noise and thickness.
2Power
If alternating current fans are used, then ventilation capability is sufficient, but noise level and energy consumption increase
Solution Approach 1:
The single fan system is divided into multiple small fans. The distributed configuration reduces vibration and noise from any single fan, and the cumulative effect of multiple small fans produces smoother, quieter air flow compared to one large fan.
Solution Approach 2:
Alternating current fans are replaced with low-voltage direct current fans. The lower voltage operation reduces motor noise, electrical hum, and mechanical vibration, significantly lowering the noise level while maintaining adequate ventilation capability.
3Power
If alternating current fans are used, then ventilation capability is sufficient, but energy consumption increases
Solution Approach 1:
The alternating current motor system is replaced with a low-voltage direct current (12-24V or 48V) electrical system. This substitution reduces energy consumption by approximately half compared to AC fans, while the multiple-fan configuration optimizes airflow efficiency to maintain adequate ventilation capability.
4Device complexity
If side air outlet is used, then structure is simple, but thermal efficiency is reduced
Solution Approach 1:
The air outlet is repositioned from the side to the front of the radiator, changing the spatial dimension of air discharge. This front outlet configuration creates more effective convection currents and improves thermal distribution in the room, enhancing thermal efficiency while maintaining structural simplicity.
5Ease of repair
If air inlet opening is far from bottom wall, then maintenance is difficult, but if close to bottom wall, then suction head passage is obstructed
Solution Approach 1:
The air inlet opening is positioned at a specific optimal location on the casing wall that balances maintenance accessibility and suction head passage requirements. This localized positioning allows vacuum cleaner access while maintaining adequate passage length for effective suction, resolving the conflict between these two requirements.
