Liquid Feeder Bypass Path Design to Prevent Pump Replacement Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server cabinets require frequent pump replacements to prevent liquid leakage in liquid cooling modules, disrupting continuous operation of servers.
Innovation Solution
A liquid feeder system with a detachable base and pump configuration that includes a base flow path and sealing mechanism, allowing for flow path switching and preventing leakage by sealing ports when the pump is removed and opening them when attached, ensuring continuous operation even when the pump is replaced or repaired.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the pump is removed from the base for maintenance, then the pump can be replaced or maintained, but liquid leakage occurs from the base flow path
Solution Approach 1:
The invention extracts the pump from the base as a detachable component, allowing the pump to be removed for maintenance while the base remains in place. The base includes separate communication ports that can be connected or disconnected from the pump, enabling pump replacement without replacing the entire liquid cooling module.
Solution Approach 2:
The invention incorporates sealing ports and sealing mechanisms in advance on the base structure. These sealing components are prepared beforehand to automatically seal the flow paths when the pump is detached, preventing liquid leakage before it can occur during pump removal or replacement operations.
2Reliability
If multiple liquid cooling modules are used for server cooling, then server continuity is maintained during module failure, but system complexity and cost increase
Solution Approach 1:
The invention divides the liquid cooling system into separable modules: a base portion and a pump portion. This segmentation allows the pump to be independently replaced without affecting the base or other cooling modules, simplifying maintenance operations compared to replacing entire cooling modules while maintaining system reliability.
3Ease of repair
If the pump is detached from the base, then pump maintenance is enabled, but liquid flow path becomes open and leakage occurs
Solution Approach 1:
The invention introduces sealing ports and sealing mechanisms as intermediary elements between the base flow path and the pump connection. These sealing components act as mediators that automatically close and seal the flow paths when the pump is detached, preventing liquid leakage while allowing pump removal for maintenance.
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 servers by preventing liquid leakage during pump replacement or failure, maintaining the cooling mechanism's functionality without the need for immediate pump replacement.
Implementation Method 1
The liquid feeder opens the bypass outflow path to cause the liquid having flowed in from the inflow port to flow from the bypass outflow path to the outflow port when the pump is removed from the base
Implementation Method 2
a base seal that seals the first base communication port when the pump is removed from the base and opens the first base communication port when the pump is attached to the base

AI summary
A liquid feeder switches a flow path of a liquid having flowed in from an inflow port to one of a flow path communicating with a first base communication port and a bypass outflow path. When a pump is attached to a base, the bypass outflow path is closed to allow the liquid having flowed in from the inflow port to flow to the pump. When the pump is removed from the base, the bypass outflow path is opened to allow the liquid having flowed in from the inflow port to flow from the bypass outflow path to the outflow port. The liquid feeder is able to prevent liquid leakage when a pump of a liquid feeder is replaced or repaired.
