Engineering Contradiction Analysis
1Reliability
If coolant flow rate is increased to prevent dry-out, then cooling reliability is improved, but energy consumption increases
Solution Approach 1:
The coolant flow rate is dynamically adjusted based on real-time monitoring of internal pressure amplitude and heat loss estimates. The system transitions from static flow rate control to dynamic control, modifying the coolant flow rate according to actual cooling conditions to prevent dry-out while minimizing energy consumption.
Solution Approach 2:
The system changes the coolant flow rate parameter based on detected internal pressure amplitude and estimated heat loss. By adjusting this key parameter in response to changing conditions, the system maintains reliable cooling while avoiding excessive energy consumption associated with continuously high flow rates.
2Reliability
If traditional refrigeration cycle is used to control coolant flow based on dryness, then cooling performance is maintained, but device complexity increases
Solution Approach 1:
The invention extracts and removes the complex refrigeration cycle components (compressor, condenser, expansion valve) from the cooling system. Instead, it uses a simplified approach with a pump, cooler, and control unit that monitors internal pressure amplitude and estimates heat loss to adjust coolant flow rate, achieving reliable cooling without the complexity of traditional refrigeration cycles.
Solution Approach 2:
The complex mechanical refrigeration cycle is replaced with a simplified control system that uses sensors to detect internal pressure amplitude and a control unit to estimate heat loss and adjust pump operation. This substitution reduces mechanical complexity while maintaining cooling performance through intelligent control.
3Reliability
If excessive coolant is supplied to ensure cooling, then cooling ability is improved, but energy consumption increases
Solution Approach 1:
The system implements feedback control by continuously monitoring the internal pressure amplitude of the coolant and using this information to estimate heat loss from the electronic component. The control unit adjusts the coolant flow rate based on this feedback, ensuring adequate cooling ability while avoiding excessive energy consumption from unnecessarily high flow rates.

AI summary
In an electronic component cooling device, a cooler cools an electronic component, a coolant temperature acquisition unit acquires a temperature of a coolant, a coolant flow rate acquisition unit acquires the flow rate of the coolant, a heat loss estimation unit estimates a heat loss from the electronic component, and a loss threshold calculation unit calculates an upper limit threshold of the heat loss from the electronic component based on the coolant temperature and the coolant flow rate. A coolant flow rate control unit controls the flow rate of the coolant and is configured to, in response to an estimated heat loss which is the heat loss from the electronic component that has been estimated by the heat loss estimation unit exceeding the upper limit threshold, increase the flow rate of the coolant circulating through the cooler.
