Distinct Cooling Board for Electronic Unit Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling systems for electronic boards in equipment, such as aircraft, are complex due to the need for multiple cooling plates and fluid connections, leading to manufacturing, usage, and maintenance challenges.
Innovation Solution
A distinct cooling board with a fluid circulation channel is used to absorb heat from electronic boards, eliminating the need for direct integration with the boards and simplifying the cooling system by allowing attachment to the equipment's walls, thus reducing complexity and improving maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If each electronic board is provided with a cooling plate integrated directly to the board, then cooling effectiveness is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The cooling system is segmented into independent functional modules: heating elements are integrated only where needed on specific electronic boards, while cooling plates are positioned separately in dedicated cooling zones. This segmentation allows cooling infrastructure to be independent of individual board configurations, reducing overall system complexity while maintaining effective cooling.
Solution Approach 2:
A fluid circulation system acts as an intermediary between the heating elements on electronic boards and the cooling plates. The fluid transfers thermal energy from heat-generating components to dedicated cooling zones, decoupling the heating and cooling functions and allowing independent optimization of each subsystem.
2Temperature
If cooling plates are fixed to each electronic board, then cooling performance is improved, but ease of manufacture and maintenance deteriorate
Solution Approach 1:
The cooling system is divided into independent modular components that can be manufactured separately and assembled later. Cooling plates are produced as standalone units without requiring integration with each specific electronic board, simplifying manufacturing processes and enabling standardized production.
Solution Approach 2:
The cooling plates are designed as universal components that can serve multiple electronic boards simultaneously from dedicated cooling zones. A single cooling plate design can be used across different board configurations, reducing the number of unique parts and simplifying manufacturing and inventory management.
3Temperature
If multiple cooling plates are integrated with multiple electronic boards, then heat dissipation is improved, but ease of operation and maintenance deteriorate
Solution Approach 1:
The cooling function is extracted from individual electronic boards and consolidated into separate, dedicated cooling zones with centralized cooling plates. This extraction allows maintenance personnel to service the cooling system independently of the electronic boards, simplifying operations and reducing the need for specialized knowledge about each board's cooling requirements.
Solution Approach 2:
The fluid circulation system serves as an intermediary that connects multiple electronic boards to centralized cooling plates. This intermediary architecture allows a single cooling plate to service multiple boards, reducing the total number of cooling components that require maintenance while ensuring adequate heat dissipation for all connected boards.
