Dynamic Thermal Control for Processor Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-performance computer hardware generates excessive heat, leading to malfunctions, hang-ups, and abnormal terminations, as traditional cooling mechanisms like heatsinks and fans often prove inadequate, especially in multifunctional devices where heat generation varies with application and function usage.
Innovation Solution
A method and apparatus that dynamically control heat generation by monitoring the state of heat generation in hardware and adjusting the operation of running applications and hardware components, such as changing processing speeds or fan operation, using a control method list to define responses to different temperature levels, ensuring efficient heat management without the need for oversized cooling systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If hardware performance is enhanced to meet high-speed processing demands, then processing speed is improved, but heat generation increases beyond the capacity of traditional cooling mechanisms
Solution Approach 1:
The patent implements dynamic thermal management by continuously monitoring temperature sensors and adjusting application operation states in real-time. The control unit dynamically changes the operation of running applications based on current temperature conditions, transitioning between different operational states to maintain thermal safety while maximizing performance when conditions permit.
Solution Approach 2:
The system changes operational parameters of applications based on temperature thresholds. When temperature exceeds predetermined thresholds, the control unit modifies application operation states (e.g., reducing CPU frequency, throttling performance). This parameter adjustment directly controls heat generation while maintaining acceptable performance levels.
2Temperature
If traditional cooling mechanisms like heatsinks and fans are used, then heat dissipation is provided, but they become inadequate when heat generation exceeds their handling capacity
Solution Approach 1:
The patent implements a feedback control system where temperature sensors continuously monitor thermal conditions and provide information to the control unit. Based on this feedback, the system automatically adjusts application operation states to prevent overheating. This closed-loop control ensures reliable thermal management without requiring oversized passive cooling infrastructure.
3Temperature
If the operation of running applications is changed to control heat generation, then temperature is regulated, but system performance may be reduced
Solution Approach 1:
The system employs periodic temperature monitoring and conditional performance adjustment. Instead of continuously throttling performance, the control unit periodically checks temperature conditions and only modifies application operation when thermal thresholds are exceeded. This allows the system to maintain high performance during normal operation while providing thermal protection when needed.

AI summary
In a control stack included in a software, a control execution unit allows a receiving unit to receive the temperatures of a main processor and a graphic processor. When it determines based on these temperatures that a thermal error has occurred, the control execution unit allows a type acquisition unit to acquire the type of an application running currently. The control execution unit then performs hardware control processing for adjusting the operation of hardware, and software control processing for changing the operation of an application, so as to control the state of heat generation in the hardware. In the software control processing, the control execution unit acquires, from a reaction table, a control method corresponding to the combination of the part where a thermal error has occurred and the type of the running application, and provides control according to the acquired control method.
