Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is additionally arranged in the liquid cooling plate, then the temperature of the cooling liquid can be directly measured, but structural complexity and cost are increased
Solution Approach 1:
The patent uses the chips as an intermediary element to indirectly measure the cooling liquid temperature. Instead of placing a temperature sensor directly in the cooling liquid channel, the system measures the temperature of the chips that are in thermal contact with the cooling liquid, and infers the cooling liquid temperature from the chip temperature and thermal resistance characteristics. This intermediary approach allows temperature measurement without modifying the liquid cooling plate structure.
Solution Approach 2:
The chips serve a dual function: they are both the computational components of the blockchain server and the temperature sensing elements. The chips' own temperature measurements, combined with known thermal resistance values, enable the system to self-determine the cooling liquid temperature without requiring separate dedicated temperature sensors in the cooling plate.
2Measurement precision
If a temperature sensor is additionally arranged in the liquid cooling plate, then the temperature of the cooling liquid can be directly measured, but cost is increased
Solution Approach 1:
The patent makes the chips multi-functional by utilizing them both for computation and for temperature sensing purposes. The same chip that performs blockchain computational tasks also serves as the temperature detection element, eliminating the need for additional dedicated temperature sensors and reducing overall system cost.
Solution Approach 2:
The system uses the chips' inherent temperature sensing capability (without additional sensors) to determine cooling liquid temperature, making the existing components serve multiple purposes and avoiding additional manufacturing costs for separate temperature measurement devices.
3Reliability
If the cooling liquid channel is closed, then the cooling liquid is contained and can effectively cool the chips, but the temperature of the cooling liquid cannot be directly read
Solution Approach 1:
The patent introduces the chips as an intermediary measurement interface. Since the chips are in direct thermal contact with the closed cooling liquid channel and their temperature can be measured, they serve as a mediator to indirectly access the cooling liquid temperature without requiring direct access to the sealed cooling liquid channel.
Solution Approach 2:
The patent replaces the direct mechanical/physical access approach (opening the cooling channel to insert a sensor) with a thermal field approach. By measuring temperature through the thermal conduction path from the cooling liquid to the chips, the system avoids the need for mechanical access to the sealed cooling channel.
