Liquid Transfer Module for Continuous Cooling Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems stop operating if the pump or liquid reservoir tank fails, as components are serially connected and lack redundancy, leading to system shutdown during maintenance or failure.
Innovation Solution
A liquid transfer module with check valves and multiple pumps connected in series to maintain pressure and flow, allowing continuous operation by relaying working liquid between the reservoir tank, pump unit, water cooling head, and liquid radiator, with quick-release connectors for easy component replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are serially connected in the liquid cooling system, then the system structure is simple, but the system stops operating when one component fails
Solution Approach 1:
The liquid cooling system is divided into multiple independent flow paths using flow guide bodies with multiple flow passages. Each flow passage can independently guide liquid flow, allowing one path to remain operational even when another path is being maintained or has failed. This segmentation enables continuous system operation while maintaining relatively simple component structures.
2Reliability
If multiple pumps are added to maintain continuous operation, then system reliability improves, but device complexity increases
Solution Approach 1:
Multiple pumps are integrated into a single pump unit with a common drive mechanism. The pump unit includes multiple pump bodies that can be driven by a single motor or control system, reducing the complexity of having multiple independent pump controls while still providing redundant pumping capability. The pumps work together to maintain liquid flow through the segmented flow paths.
3Reliability
If check valves are installed in each flow passage, then liquid flow direction is controlled for continuous operation, but manufacturing complexity increases
Solution Approach 1:
The flow guide bodies are designed with universal, standardized flow passages that can serve multiple functions. Each flow passage is equipped with check valves that not only control liquid flow direction but also prevent backflow and maintain pressure differentials. The standardized design of these multi-functional components simplifies the manufacturing and assembly process despite the added reliability features.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous operation of the liquid cooling system by maintaining liquid flow and pressure even when components are replaced or fail, ensuring uninterrupted heat dissipation and system functionality.
Implementation Method 1
a check valve being disposed in each of some flow passages of the first flow guide passage set for limiting the flowing direction of the working liquid
Implementation Method 2
at least two pumps are serially connected by means of flow passages to pressurize the working liquid in the liquid cooling system so as to increase the pressure of the working liquid and speed the flowing of the working liquid
Implementation Method 3
The water cooling head is in contact with the heat source to heat-exchange with the heat source so as to transfer the heat of the heat source to a working liquid
Implementation Method 4
The liquid radiator serves to dissipate the heat of the working liquid passing through the water cooling head

AI summary
A liquid transfer module is applied to a liquid cooling system. The liquid transfer module includes a first flow guide body and a second flow guide body removably connected with a liquid reservoir tank and a pump unit. The first and second flow guide bodies are formed with multiple internal flow passages. Some of the flow passages communicate with each other via a check valve and some other flow passages communicate with each other via an opening. The liquid transfer module serves to transfer and guide a working liquid to flow through the liquid reservoir tank and the pump unit.
