Liquid Feeder Bypass Sealing for Pump Replacement Without Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server cabinets require frequent pump replacements to prevent liquid leakage in liquid cooling modules, which can lead to system downtime and increased maintenance costs.
Innovation Solution
A liquid feeder system with a detachable base and pump configuration that includes a base flow path and sealing mechanism, allowing for the diversion of liquid flow through a bypass path when the pump is removed, preventing leakage and enabling continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the pump is removed from the liquid cooling module for replacement or repair, then the pump can be maintained or replaced, but liquid leakage occurs from the communication ports
Solution Approach 1:
The sealing ports are opened in advance when the pump is attached to the base, and closed when the pump is removed, preventing liquid leakage before it can occur during pump replacement
Solution Approach 2:
The sealing ports act as an intermediary mechanism between the base flow path and the external environment, controlling liquid flow by opening or closing based on pump attachment state
2Reliability
If multiple liquid cooling modules are used for server cooling, then continuous operation can be maintained when one module fails, but the system complexity increases
Solution Approach 1:
The liquid cooling system is divided into independent modular units (base and pump), allowing individual modules to be replaced without affecting other modules, thus maintaining continuous operation
Solution Approach 2:
The base unit with detachable pump design serves multiple functions: it can work with different pump units, allow for easy replacement, and maintain cooling capability throughout the replacement process
3Productivity
If the pump operates for a long time to cool servers, then the servers can continuously operate, but the pump may fail and cause liquid leakage
Solution Approach 1:
The pump can be easily discarded (removed) and replaced when it fails, while the base unit with liquid reservoir remains in place, allowing for quick recovery without discarding the entire cooling system
Solution Approach 2:
The sealing ports are prepared in advance to automatically seal when the pump is removed, preventing liquid leakage before it can occur during pump failure or replacement
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
The system prevents liquid leakage and allows for continuous operation of servers even when a pump is removed for maintenance, reducing downtime and maintenance costs by ensuring uninterrupted liquid flow through the bypass path.
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.
