Multi-Outlet Heat Dissipation Fan for Obstruction Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat dissipation fans, such as axial and centrifugal fans, are prone to overheating when their outlets are obstructed, as they are designed to dissipate heat in a single direction, leading to reduced cooling efficiency.
Innovation Solution
A heat dissipation fan design featuring a base plate with multiple air outlets, including a primary air outlet and a secondary air outlet oriented at an angle, allowing airflow to discharge through either outlet, ensuring continued cooling efficiency even if one outlet is blocked, with a stator and rotor configuration that enhances airflow distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single outlet is used for heat dissipation, then the device structure is simple, but the cooling reliability deteriorates when the outlet is obstructed
Solution Approach 1:
The single outlet is divided into multiple outlets (first outlet and second outlet) with different orientations. The first outlet extends in a first direction while the second outlet extends in a second direction that is not parallel to the first direction. This segmentation ensures that if one outlet is obstructed, heat dissipation can continue through the other outlet, thereby improving cooling reliability without requiring complex redundant systems.
Solution Approach 2:
The outlets are arranged in different spatial directions rather than simply providing multiple outlets in the same direction. The first outlet and second outlet extend in non-parallel directions, creating a three-dimensional heat dissipation architecture. This dimensional approach allows the system to maintain cooling effectiveness from multiple angles, improving reliability while keeping the structural complexity manageable.
2Adaptability or versatility
If the outlet orientation is fixed in a single direction, then the fan structure is simple, but the adaptability to different mounting conditions deteriorates
Solution Approach 1:
The outlet function is segmented into multiple independent outlets with different orientations. The first outlet is configured for heat dissipation in one direction while the second outlet provides heat dissipation in another direction. This segmentation allows the fan to adapt to different mounting conditions and spatial constraints, improving versatility without requiring multiple separate fan units.
Solution Approach 2:
The fan structure is designed to perform multiple heat dissipation functions through its multiple outlets. The same fan body can dissipate heat in multiple directions simultaneously, making it universally applicable to various mounting scenarios and electrical device configurations. This multi-functionality approach enhances adaptability while avoiding the complexity of multiple separate devices.

AI summary
A heat dissipation fan includes a base plate, a frame formed on a side of the base plate, a stator received sin the frame, and a rotor below the stator and connected with the stator. The heat dissipation fan also has an air inlet, a first air outlet and a second air outlet. The air inlet is communicated with the first air outlet and the second air outlet. An angle is defined between each of the first air outlet and the second air outlet.
