Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multiple-input and multiple-output (MIMO) antenna systems face limitations in cooling performance due to the restricted heat contact area of conventional cooling parts and the need for separate blowing fans, especially when dealing with multiple heat-generating elements in a limited space.
Innovation Solution
The proposed solution involves a multiple-input and multiple-output antenna apparatus with a housing design that incorporates a radome, PCB assembly, top cooling part, and side cooling part, utilizing heat pipe groups for efficient heat transfer and dissipation without the need for a separate blowing fan. The design includes bottom and top cooling ribs, a heat transfer block, and a heat pipe group to effectively dissipate heat from multiple heat-generating elements within the limited space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate blowing fan is used to exhaust heat from the housing, then heat dissipation capability is improved, but device complexity and power consumption increase
Solution Approach 1:
The housing structure itself performs the cooling function through integrated cooling ribs and heat dissipation channels, eliminating the need for external blowing fans. The design uses natural convection and structured heat pathways to achieve self-cooling, thereby reducing device complexity while maintaining effective heat dissipation.
2Temperature
If cooling ribs are provided in direct contact with heat-generating elements, then heat transfer efficiency is improved, but the heat contact area is limited in multi-element configurations
Solution Approach 1:
The housing is divided into multiple cooling ribs that are distributed across different locations, each contacting or near different heat-generating elements. This segmentation allows multiple parallel heat transfer pathways, effectively increasing the total heat contact area without requiring a single large cooling surface.
Solution Approach 2:
The cooling ribs extend in multiple spatial dimensions within the housing structure, creating three-dimensional heat dissipation pathways. This dimensional expansion allows heat to be transferred from multiple angles and surfaces, significantly increasing the effective heat contact area beyond what a single-plane cooling solution could provide.
