Modular Fan Frame Splicing for Low-Noise Electronic Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan configurations in electronic products face issues of noise, resonance, and reduced aesthetic appeal due to direct attachment to casings or the need for additional brackets, which also affect depth design and storage management.
Innovation Solution
A fan frame design featuring a body with positioning holes and members that allows for free splicing and distance adjustment between fan frames, eliminating the need for additional fixing brackets and enabling flexible installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fans are directly attached to the casing, then the solution is most cost-effective, but it causes noise and resonance issues and is not aesthetically pleasing
Solution Approach 1:
The fan assembly is segmented into modular fan frames that can be independently positioned and adjusted within the casing, separating the fan from direct contact with the casing structure, thereby reducing noise and resonance while maintaining cost-effectiveness
Solution Approach 2:
Positioning members act as intermediary elements between the fan frame and the casing, providing adjustable spacing and decoupling the fan from the casing to eliminate noise and resonance issues while keeping the overall structure simple and cost-effective
2Object-affected harmful factors
If additional fan brackets are used to fix fans, then aesthetic, noise, and resonance issues are solved, but the space reserved for screws affects depth design and storage management
Solution Approach 1:
The positioning members serve multiple functions: they provide adjustable spacing to control noise and resonance, eliminate the need for separate fixing brackets, and allow for flexible depth design. This multi-functionality reduces overall device complexity while solving the noise and aesthetic issues
Solution Approach 2:
The positioning members are designed to be adjustable rather than fixed, allowing dynamic reconfiguration of fan spacing and positioning. This adaptability eliminates the need for multiple fixed bracket designs for different configurations, simplifying storage management and depth design
3Productivity
If multiple fans are arranged side by side, then heat dissipation effectiveness is improved, but the configuration requires either direct attachment (causing noise) or additional brackets (affecting depth design)
Solution Approach 1:
Multiple fans are arranged as independent modular units within separate fan frames, each with its own positioning members. This segmentation allows each fan to be independently positioned to optimize heat dissipation while maintaining adjustable spacing to reduce noise and resonance between adjacent fans

AI summary
A fan frame, a fan module, and an electronic device are proposed. The fan module includes a plurality of fan frames and a plurality of fan blades. The fan frames are connected to each other along a connecting direction. Each of the fan frames includes a body, a first frame and at least two positioning members. The first frame is connected to one end of the body and includes a first connecting part, at least two positioning holes and a second connecting part. The at least two positioning holes are spaced apart from each other on the first connecting part. The second connecting part is opposite to the first connecting part. The at least two positioning members are spaced apart from each other on the second connecting part. The fan blades are respectively disposed in the fan frames.
