Remote Radio Module Mounting Kit Integrated Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to design a heat dissipation architecture for remote radio modules (RRU) that ensures effective heat removal while maintaining a compact and miniaturized size, as the increasing output power of RRU modules leads to higher heat consumption and requires more efficient cooling solutions without increasing the module's size or weight.
Innovation Solution
The proposed solution integrates a mounting kit with a fastening part, a ventilation part, and an air supply part, where the air supply part is located on the mounting kit, allowing air to flow through a ventilation channel to the remote radio module, eliminating the need for a separate fan box and enabling stronger airflow for enhanced heat dissipation. This configuration keeps the remote radio module thin and small by integrating the ventilation and air supply components within the mounting kit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an air-cooled heat dissipation manner with an externally hung fan box is used for a single RRU device, then heat dissipation capability is improved, but the size of the RRU increases
Solution Approach 1:
The patent combines the fan box with the mounting bracket to form an integrated heat dissipation assembly. The fan is mounted within the bracket structure itself, merging the support function and heat dissipation function into a single component. This eliminates the need for a separate externally hung fan box, thereby improving heat dissipation capability while avoiding additional volume increase to the RRU device.
Solution Approach 2:
The mounting bracket is designed to serve multiple functions: mechanical support for the RRU device, structural mounting interface, and heat dissipation component housing the fan. By making the bracket universal and multi-functional, the patent avoids adding separate components for each function, thus improving heat dissipation without increasing the overall size of the RRU assembly.
2Power
If output power of an RRU module is increased, then communication performance is improved, but heat consumption increases
Solution Approach 1:
The patent converts the harmful effect of increased heat consumption (resulting from higher output power) into a beneficial design driver. By integrating the fan directly into the mounting bracket, the design uses the necessary cooling infrastructure as an opportunity to improve heat dissipation efficiency. The mounting bracket, which must exist anyway for mechanical support, is transformed into an active heat dissipation component, thereby managing the heat generated by high-power operation more effectively.
3Temperature
If a separate fan box is externally hung on an RRU device, then heat dissipation is improved, but product miniaturization is hindered
Solution Approach 1:
The patent merges the fan box with the mounting bracket to eliminate the need for a separate externally hung fan box. The fan is installed within the bracket structure, combining the heat dissipation function with the existing mechanical support structure. This integration maintains heat dissipation efficiency while avoiding the additional length and volume that would result from a separate fan box attachment.
Solution Approach 2:
Instead of adding the fan box as a separate external component that increases the RRU's length and volume, the patent embeds the fan within the two-dimensional plane of the mounting bracket. This dimensional reorganization allows the heat dissipation component to occupy space that would otherwise be structural, thereby maintaining compact dimensions while achieving effective heat dissipation.

Function Achieved in This Case
This design effectively dissipates heat from the remote radio module, allowing for a compact and efficient heat dissipation system that supports higher power consumption without increasing the module's size, and allows for flexible selection of air sources based on heat dissipation requirements, promoting miniaturization and improved heat management.
Implementation Method 1
an air source is disposed inside the air supply part... so that an air flow generated by the air source reaches the remote radio module after passing through the ventilation channel, to dissipate heat for the remote radio module
Implementation Method 2
