Engineering Contradiction Analysis
1Use of energy by moving object
If air-cooling systems are used for electronic components, then the system structure is simple, but cooling efficiency is poor and power consumption is high
Solution Approach 1:
The patent implements a liquid cooling system using coolant circulation through channels in contact with electronic components. The pump drives coolant flow through the system, and the liquid medium efficiently transfers heat from hot components to heat exchangers, resolving the contradiction between simple air-cooling structure and poor cooling efficiency.
Solution Approach 2:
The system utilizes phase change of the coolant (liquid to vapor and back) to absorb and release large amounts of latent heat during evaporation and condensation processes. This phase transition mechanism dramatically improves cooling efficiency compared to conventional air-cooling, while the two-phase operation mode optimizes heat transfer performance.
2Temperature
If pump-driven cooling is used, then cooling performance is improved, but system reliability decreases due to pump failure risk
Solution Approach 1:
The system incorporates passive cooling pathways and backup cooling mechanisms that activate automatically when the pump fails. The design includes alternative coolant flow routes and passive heat dissipation structures that provide redundancy, ensuring continuous cooling protection even when the active pump-driven system malfunctions.
Solution Approach 2:
The system employs passive cooling mechanisms that operate autonomously without requiring pump power. When the pump fails, natural convection and phase change processes continue to provide cooling through thermally-driven fluid movement, allowing the system to self-regulate and maintain cooling functionality without external intervention.

AI summary
Techniques that facilitate two-phase liquid cooling electronics are provided. In one example, a system comprises a pump and a valve. The pump circulates a coolant refrigerant through a two-phase refrigerant system associated with an electronic component. The valve controls a flow path of the coolant refrigerant that flows through the two-phase refrigerant system. Furthermore, the valve modifies the flow path of the coolant refrigerant through the two-phase refrigerant system in response to a determination that an operation of the pump satisfies a defined criterion.
