Dual-Sided Optical Package With Embedded Coolant Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The number of optical packages in electronic devices is limited by the size, cost, and weight of the optical package, particularly due to the base plate on which optical components are mounted, which also requires effective heat removal to prevent overheating.
Innovation Solution
A dual-sided optical package design featuring a base plate with a coolant channel and optics mounted on both sides, allowing for reduced size, weight, and cost, with the coolant channel aiding in heat removal through liquid coolant flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional single-sided optical package is used, then the structure is simple and manufacturing is easier, but the package size, weight, and cost increase
Solution Approach 1:
The patent applies dual-sided mounting by utilizing both sides of the base plate for mounting optical components. Instead of mounting all components on a single side (traditional approach), the invention distributes components across two sides of the base plate, effectively using the third dimension (z-axis) to reduce the footprint area while maintaining functional capacity.
2Productivity
If more optical packages are installed in electronic devices, then optical signal capacity increases, but device size and weight increase
Solution Approach 1:
The patent combines two optical packaging functions into a single base plate structure. By mounting two sets of optics on opposite sides of the same base plate, the invention effectively merges what would traditionally require two separate packages into one integrated unit, thereby increasing optical signal capacity without proportionally increasing device volume.
3Quantity of substance
If a larger base plate is used to mount optical components, then component mounting capacity increases, but heat removal capability decreases
Solution Approach 1:
The patent addresses heat removal by utilizing the vertical dimension through coolant channels embedded within the base plate thickness. Instead of relying solely on lateral heat dissipation from a larger surface area, the invention incorporates internal coolant flow paths that traverse the base plate, enabling efficient heat extraction from multiple mounting locations without increasing the lateral footprint.
