Pressure Relief Device for Liquid Cooling Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cooling systems face limitations in heat dissipation efficiency and noise levels as CPU processing speeds increase, and liquid cooling systems suffer from high pressure due to air in the pipes, which can lower performance and cause damage.
Innovation Solution
A pressure relief device with an exhaust valve and valve seat is integrated into the liquid cooling system, allowing air to be discharged from the pipes, thereby separating air from the liquid and reducing system pressure, enhancing heat-dissipation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid cooling system is used to improve heat-dissipation efficiency, then heat dissipation performance is improved, but air accumulates in pipes causing high pressure that lowers performance and may cause damage
Solution Approach 1:
The patent extracts and removes air from the liquid cooling system by installing a pressure relief device with an exhaust valve at the highest point of the system. The exhaust valve opens when air pressure accumulates, allowing air to be discharged from the pipes, thereby preventing high pressure damage and maintaining reliable system operation while preserving the high heat-dissipation efficiency of liquid cooling.
2Reliability
If air is discharged from the system to reduce pressure, then system pressure is reduced and reliability is improved, but additional components are added to the system
Solution Approach 1:
The pressure relief device integrates multiple functions into a single component: it serves as both a pressure relief mechanism and an air discharge valve. The exhaust valve is designed to automatically open when air pressure accumulates, performing both pressure regulation and air venting functions simultaneously, thereby improving reliability without significantly increasing system complexity.
3Device complexity
If conventional air cooling is used to maintain simple system structure, then device complexity is low, but heat-dissipation efficiency is insufficient for high-speed CPUs
Solution Approach 1:
The patent introduces a pressure relief device as an intermediary component that enables the liquid cooling system to operate reliably by removing air accumulations. This intermediary device resolves the conflict between using complex liquid cooling for high heat dissipation and maintaining system simplicity, as the pressure relief device is a relatively simple addition that enables the more efficient liquid cooling method to function properly.

AI summary
A pressure relief device is applied to a liquid cooling system. The pressure relief device includes an exhaust valve and a valve seat. The valve seat is connected with the exhaust valve to form a chamber. The valve seat has an inlet, an outlet and a protrusion. The inlet and the outlet are individually communicated with the chamber. The protrusion is located at the bottom of the valve seat and protrudes toward the exhaust valve. A liquid cooling system with the pressure relief device is also disclosed.
