Problem

GPU accelerator cards generate excessive heat during high-intensity calculations, leading to inefficient heat dissipation control cycles that can result in delayed temperature monitoring and increased safety risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the heat dissipation control cycle is shortened to enable timely temperature monitoring, then the response speed to temperature changes is improved, but the system complexity and information reading burden increase

Engineering Contradiction:
Improvetemperature monitoring speedVSAvoidheat dissipation control system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent segments the information reading process by identifying critical parameters (temperature, fan speed, GPU status) that must be monitored versus optional parameters. The controller reads only essential information within the optimized control cycle, dividing the monitoring task into priority levels to reduce system complexity while maintaining fast response capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic optimization of the heat dissipation control cycle based on GPU workload and temperature conditions. When GPU utilization is high or temperature approaches thresholds, the control cycle is shortened for faster monitoring. When GPU is idle or temperature is low, the cycle is extended to reduce reading frequency and system burden, making the monitoring speed adaptive rather than fixed.

Inventive Principle:
Principle #15Dynamics

2Loss of information

If more information is read within each heat dissipation control cycle, then the comprehensive monitoring capability is improved, but the time required for each control cycle increases

Engineering Contradiction:
Improvetemperature information completenessVSAvoidheat dissipation control cycle duration
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent extracts and prioritizes only the most critical information elements needed for heat dissipation control: GPU temperature, fan speed status, and GPU operational state. Non-essential information is excluded from the mandatory reading list in each control cycle, allowing comprehensive temperature monitoring to be achieved with minimal reading time while maintaining complete visibility of temperature-related parameters.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies partial action by reading only the subset of information necessary for effective heat dissipation control rather than all possible GPU parameters. This selective reading approach achieves sufficient monitoring coverage for temperature management without the time penalty of reading excessive or redundant information, optimizing the balance between information completeness and cycle duration.

Inventive Principle:
Principle #16Partial or excessive action

3Temperature

If the fan speed is continuously adjusted based on temperature information, then the heat dissipation effectiveness is improved, but the energy consumption increases

Engineering Contradiction:
ImproveGPU temperature controlVSAvoidfan energy consumption
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic fan speed adjustment based on the optimized heat dissipation control cycle rather than continuous adjustment. The fan speed is modified at discrete intervals determined by the control cycle, which itself adapts to GPU workload and temperature conditions. This periodic approach maintains effective temperature control while reducing fan energy consumption compared to continuous adjustment, as the fan operates at stable speeds between adjustment points rather than constantly changing.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent changes the operational parameters of the fan based on temperature thresholds and GPU workload levels. Instead of continuous fine-grained adjustment, the system modifies fan speed to discrete parameter levels (e.g., low, medium, high, maximum) based on temperature conditions. This parameter-based control achieves effective heat dissipation while minimizing energy consumption by avoiding unnecessary intermediate speed changes and allowing the fan to operate efficiently at optimized speed levels.

Inventive Principle:
Principle #35Parameter changes

AI summary

Disclosed is an optimization method for heat dissipation control. An information reading frequency and an optimized heat dissipation control cycle of each GPU accelerator card are obtained. A maximum number of information readings of each GPU accelerator card within one optimized heat dissipation control cycle is obtained according to the information reading frequency and the optimized heat dissipation control cycle. Other information, in addition to the temperature information, to be read during a current heat dissipation control cycle is determined, so that the sum of the temperature information and other information to be read does not exceed the maximum number of information readings. An information reading instruction is generated and transmitted to each GPU accelerator card according to the temperature information and other information to be read. In each optimized heat dissipation control cycle, a fan speed is adjusted according to the temperature information received from each GPU accelerator card.
