Optical Module Pull Ring Structure for Better Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical modules generate significant heat during operation, which if not dissipated effectively, affects their stability, and the presence of a pull ring reduces the length of heat dissipation fins, leading to poor heat dissipation efficiency.
Innovation Solution
The optical module design includes a housing with heat dissipation fins and a pull ring assembly featuring a connecting arm that covers the heat dissipation fins, allowing for extended fin length and forming closed channels for improved airflow, along with an elastic component for easy module removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pull ring is added to enable detachable plugging of the optical module, then the ease of operation is improved, but the length of the heat dissipation fins is reduced, causing heat dissipation efficiency to deteriorate
Solution Approach 1:
The patent embeds the pull ring assembly within the housing structure, with the pull ring positioned inside the housing cavity rather than extending externally. This nesting approach allows the pull ring to function for detachable plugging while not reducing the external dimensions of the heat dissipation fins, thereby resolving the contradiction between ease of operation and heat dissipation efficiency
Solution Approach 2:
The patent repositions the pull ring assembly from an external lateral position to an internal position along the lengthwise direction of the housing. By moving the pull ring to a different spatial dimension (inside the housing rather than outside), the design maintains full heat dissipation fin length while preserving the detachable plugging function
2Temperature
If the heat dissipation fins are extended to improve heat dissipation effect, then the heat exchange area is increased, but the space occupied by the pull ring is increased, affecting the compactness of the housing
Solution Approach 1:
The pull ring assembly is nested within the housing volume, utilizing internal space that would otherwise be unused. This allows the heat dissipation fins to extend to their full required length for optimal heat dissipation effect, while the pull ring occupies space within the housing rather than adding to the external dimensions

Implementation Method 1
a heat dissipation fin disposed on one end of the housing adjacent to the optical interface
Implementation Method 2
the heat dissipation fins are spaced apart on one surface of the housing in a direction perpendicular to the lengthwise direction of the housing, and the heat dissipation fins adjacent to each other defines a heat dissipation channel therebetween

AI summary
An optical module includes a housing, an optical interface and an electrical interface being formed at two opposite ends of the housing along a lengthwise direction, respectively; a heat dissipation fin, disposed at the end of the housing close to the optical interface; and a pull ring assembly, comprising a ring arm and a connecting arm connected to each other, the ring arm and the connecting arm being located at different sides of the housing, respectively, and the connecting arm covering a side of the heat dissipation fin facing away from the housing.
