Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing heat-dissipating fin structure for antenna apparatuses suffers from heat stagnation due to restricted airflow, which degrades the heat-dissipating performance as outside air cannot effectively flow into the connection parts between the heat-dissipating fins and the cover.
Innovation Solution
A cooling device with wave heat-dissipating fins that extend to form curved surfaces and are angled to allow airflow in all directions, featuring a mounting thermal conduction plate with flanges to facilitate thermal contact and minimize flow resistance, enabling smooth airflow and improved heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If straight heat-dissipating fins are used, then the structure is simple, but heat stagnation occurs at the connection part and heat-dissipating performance degrades
Solution Approach 1:
The patent applies curvature to the heat-dissipating fins by forming wave-shaped patterns on the fin surfaces. This curvature modifies the airflow pattern around the fins, allowing air to flow more effectively into the connection parts between fins and the cover, thereby preventing heat stagnation while maintaining structural simplicity.
2Strength
If the width of heat-dissipating fins is increased, then structural stability is improved, but airflow is blocked and heat dissipation efficiency decreases
Solution Approach 1:
The wave-shaped curved surfaces on the fins create optimized airflow channels that allow sufficient air intake even with wider fin structures. The curvature guides air flow along the fin surfaces, reducing turbulence and improving heat transfer efficiency without compromising structural stability.
3Area of stationary object
If fins are arranged closely together, then heat dissipation surface area is increased, but airflow resistance increases and heat stagnation occurs
Solution Approach 1:
The wave-shaped curvature on closely spaced fins creates a flowing airflow pattern that reduces resistance between adjacent fins. The curved surfaces guide air smoothly through the fin array, allowing high surface area density without significant airflow blockage or heat stagnation.

AI summary
The present invention relates to a cooling device for an antenna apparatus. Particularly, the cooling device comprises a heat-dissipating cover which has an inner surface exposed to a thermal space and an outer surface exposed to the outside where outside air flows, and multiple wave heat-dissipating fins which are disposed in multiple rows on the outer surface of the heat-dissipating cover so as to be thermally conductive, and form curved surfaces that are continuous from the outer surface of the heat-dissipating cover to a discretionary height, in which the horizontal cross-sections at the discretionary height have straight-line shapes in which same are rotated by a predetermined angle in any one direction from the horizontal cross-sections on the outer surface of the heat-dissipating cover. Therefore, the present invention provides the advantage of enhancing heat-dissipating performance.
