Solution Overview
Problem
Existing heat exchange systems for integrated circuits lack control over heat transfer between components, leading to undesired heat dissipation when one component generates more heat than others, potentially exceeding the temperature threshold of other components.
Innovation Solution
A controllable heat transfer medium and sensor system are integrated into the circuit board, allowing for active management of heat transfer between components through valves and heat exchangers, with sensors monitoring temperatures to activate or deactivate heat exchangers and control airflow subsystems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a passive heat transfer medium is used to transfer heat between circuit board components, then heat dissipation is simplified and continuous, but heat cannot be controlled and may cause overheating of components with lower temperature thresholds
Solution Approach 1:
The patent transforms the passive heat transfer medium into an active, controllable system by introducing valves that can dynamically open or close heat transfer paths. The heat transfer medium is no longer static in its function but can be actively regulated based on real-time temperature conditions of different components, resolving the contradiction between continuous heat dissipation and controllable heat transfer.
Solution Approach 2:
The patent implements a feedback control mechanism where temperature sensors monitor the thermal state of circuit board components and provide signals to control valves. This feedback loop enables the system to automatically adjust heat transfer paths based on actual temperature conditions, preventing overheating while maintaining efficient heat dissipation, thus resolving the control issue.
2Temperature
If heat is transferred from high-heat-generating components to other components, then cooling of hot components is improved, but components with lower temperature thresholds may be overheated
Solution Approach 1:
The patent applies local quality control by introducing individual control valves for different heat transfer paths originating from high-heat-generating components. Each valve can be independently controlled based on the specific temperature conditions and thermal requirements of target components, allowing selective heat transfer to only those components that can safely accept the heat, thus preventing overheating of sensitive components.
Solution Approach 2:
The patent changes the operational parameters of the heat transfer system by using control valves to regulate the flow rate and direction of the heat transfer medium. By dynamically adjusting these parameters based on temperature sensor feedback, the system can optimize cooling of hot components while preventing harmful heat transfer to temperature-sensitive components.
3Ease of operation
If control valves and sensors are added to enable selective heat transfer, then heat transfer control is improved, but system complexity increases
Solution Approach 1:
The patent implements a self-service control system where temperature sensors automatically detect thermal conditions and trigger appropriate valve actions without requiring external intervention. The system uses simple control logic where sensors monitor temperature and directly influence valve states, enabling automatic heat transfer control while minimizing the need for complex external control mechanisms.
