Compound-Tooth Radiator Channels for Wind-Resistant Base Station Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiators for communication base stations suffer from poor heat dissipation due to single fin structures, which are affected by wind and lead to temperature rises, and increasing fin height or volume to improve heat dissipation results in cost and weight increases, limited by die-casting technology.
Innovation Solution
A combined fin radiator design with straight and inclined fins, including air ducts and derivation fins, enhances convective heat transfer and air flow management to improve heat dissipation without increasing volume or weight, using integral die casting for structural integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the fin height of heat radiating fins is increased to improve heat dissipation, then heat radiating capability is improved, but cost and weight increase
Solution Approach 1:
The radiator is divided into multiple heat radiating fins with different structures (straight fins and V-shaped inclined fins) arranged in groups. This segmentation allows each fin type to perform specific functions - straight fins for stable heat radiation and inclined fins for wind-resistant performance - thereby improving overall heat dissipation without needing to increase the height of individual fins excessively
Solution Approach 2:
The patent introduces V-shaped inclined fins that tilt at specific angles (30-60 degrees) relative to the vertical direction, adding a dimensional aspect to the fin structure. This angular arrangement creates wind-resistant channels that guide hot air flow while maintaining compact fin height, thus improving heat dissipation performance without proportional increases in weight
2Temperature
If the fin height of heat radiating fins is increased to improve heat dissipation, then heat radiating capability is improved, but manufacturing cost increases
Solution Approach 1:
The radiator body is divided into multiple modular heat radiating fins that can be manufactured separately and then assembled. This segmentation allows for standardized production of fin components using conventional die-casting processes, avoiding the need for expensive high-height fin manufacturing while achieving improved heat dissipation through optimized fin arrangements
Solution Approach 2:
The patent employs V-shaped inclined fins with specific tilt angles (30-60 degrees) that dynamically adapt to wind conditions. This angular design allows hot air to flow along the inclined surfaces and escape through wind-resistant channels, improving heat dissipation efficiency without requiring excessive fin height that would increase manufacturing complexity and cost
3Temperature
If a single V-shaped inclined fin structure is used to improve heat dissipation, then heat radiating capability is improved, but wind resistance deteriorates
Solution Approach 1:
The radiator incorporates multiple groups of heat radiating fins with different orientations - straight fins (first group) and V-shaped inclined fins (second group). The straight fins provide stable vertical heat radiation, while the inclined fins create angled channels. This segmentation of fin types works synergistically to maintain heat dissipation performance while resisting wind interference
Solution Approach 2:
The V-shaped inclined fins are arranged asymmetrically with specific tilt angles (30-60 degrees) relative to the vertical direction. This asymmetric angular arrangement creates wind-resistant channels that guide hot air flow at angles, preventing direct wind impact from disrupting natural convection. The asymmetric design allows hot air to escape along the inclined surfaces even when wind blows from various directions
4Temperature
If the overall volume of radiator is enlarged to improve heat dissipation, then heat radiating capability is improved, but weight increases
Solution Approach 1:
The radiator employs multiple heat radiating fins with different structures (straight and V-shaped inclined) arranged in distinct groups within a compact configuration. This segmentation allows efficient use of available space, achieving improved heat dissipation through optimized fin arrangements rather than simply enlarging the overall radiator volume, thus avoiding proportional weight increases
Solution Approach 2:
The V-shaped inclined fins introduce angular dimensions (30-60 degree tilts) to the heat radiating structure, creating three-dimensional wind-resistant channels. This dimensional approach improves heat dissipation performance by guiding hot air flow along inclined paths without requiring proportional increases in radiator volume or weight
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combined fin radiator design reduces component temperatures by 5-8 degrees at the top and 4 degrees at the bottom, improving heat dissipation by 20-30% and enhancing outdoor reliability by preventing hot air accumulation and wind interference.
Implementation Method 1
the heat radiating fins may be of a single V-shaped inclined fin structure, and an inclined air-out manner is used. However, when there is wind outdoors, such a structure is easily affected by the headwind to the natural convection
Implementation Method 2
a first heat radiating assembly and a second heat radiating assembly, wherein the first air ducts formed by the first straight fins are communicated with the third air ducts formed by the inclined fins, so that the air inlet channels and outlet channels of a traditional radiator using natural convection heat radiating are optimized, the convective heat transfer of the cold air on the first straight fins and the inclined fins is enhanced
