5G Outdoor Unit Support Frame for Cooling Without Bulk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 5G outdoor units face issues with inadequate heat dissipation, bulkiness, and high manufacturing costs due to integrally formed covers and support frames, which hinder efficient operation and installation, and require new molds for different environments.
Innovation Solution
The 5G outdoor unit design separates the main body and support frame, allowing for easy assembly and reduced weight, with the support frame featuring heat dissipation fins and channels for enhanced heat transfer, and the cover and support frame being independent components that can be molded separately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the cover and support frame are integrally formed, then the structural strength is improved, but the device becomes bulky and heavy, and manufacturing cost increases
Solution Approach 1:
The patent divides the cover and support frame into separate components. The cover is detached from the support frame, allowing each part to be optimized independently. This segmentation reduces overall device weight while maintaining structural integrity through proper connection design at the mounting bracket interface.
2Stability of the object's composition
If the cover and support frame are integrally formed, then the structural stability is improved, but the device complexity and manufacturing cost increase due to requiring new molds for different environments
Solution Approach 1:
By separating the cover from the support frame, the patent enables independent manufacturing of each component. Standardized molds can be reused for the cover across different environmental configurations, while only the support frame requires customization. This significantly reduces mold complexity and manufacturing cost.
Solution Approach 2:
The cover is designed as a universal component that can be paired with different support frame configurations for various environments. This multi-functionality approach allows a single cover mold to serve multiple applications, reducing the need for specialized molds for each environmental condition.
3Temperature
If heat dissipation holes are opened on the cover, then the heat dissipation effect is improved, but the waterproof and dustproof performance deteriorates
Solution Approach 1:
The patent extracts the heat dissipation function from the cover by providing dedicated heat dissipation structures on the support frame. This separation allows the cover to maintain its sealed, waterproof, and dustproof integrity while the support frame handles thermal management through its open heat dissipation fins and channels.
Solution Approach 2:
The support frame acts as an intermediary structure that provides heat dissipation pathways between the internal components and the external environment. The heat dissipation fins and channels on the support frame serve as thermal conduits, enabling effective heat rejection without compromising the cover's protective sealing.
4Temperature
If sheets are disposed on the outside of the cover for heat dissipation, then some heat dissipation is achieved, but the overall heat dissipation effect is not ideal and the device becomes bulkier
Solution Approach 1:
The patent merges the heat dissipation function with the support frame structure itself. The heat dissipation fins and channels are integrated into the support frame's design, eliminating the need for separate external sheets. This integration achieves effective heat dissipation while minimizing additional device volume.

Function Achieved in This Case
This design improves heat dissipation efficiency, reduces unit volume and weight, and lowers mold development costs by allowing the support frame to be adapted for different environments without altering the main body's shape.
Implementation Method 1
the support frame comprises a first side plate, a second side plate, and a plurality of heat dissipation fins; the first side plate is disposed on the outer side of the cover; the heat dissipation fins are disposed between the first side plate and the second side plate at intervals, with a channel formed between two adjacent heat dissipation fins
Implementation Method 2
heat dissipation fins are disposed between the first side plate and the second side plate at intervals

AI summary
A 5G outdoor unit having a heat dissipation function includes a main body and a support frame. The main body includes a housing, a cover, and an antenna, the cover is mounted on one side of the housing, and the antenna is disposed on an inner side of the cover. The support frame includes a first side plate, a second side plate, and a plurality of heat dissipation fins. The first side plate is mounted on an outer side of the cover, the fins are arranged between the first side plate and the second side plate at intervals, and a channel is formed between the two adjacent heat dissipation fins. As such, the main body and the support frame are two separate elements. The volume of the main body is reduced, and the weight of the main body is less.
