Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems for rack-mounted processing assemblies suffer from the buildup of contaminants such as mineral deposits, corrosion, and algae, which affect the efficiency and quality of the cooling process.
Innovation Solution
A maintenance cleansing system with multiple tanks containing different liquids (detergent, softened water, treated osmosed water with corrosion inhibitors) and a control module that executes cleansing cycles with specific durations, using pumps, solenoid valves, and filters to maintain operation of the data processing assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If direct liquid cooling blocks with internal channels are used to cool high heat-generating components, then cooling efficiency is improved, but contaminant buildup (mineral deposits, corrosion, algae, bacteria) occurs in the channels
Solution Approach 1:
The system performs preliminary cleaning actions by circulating cleaning solutions through the cooling channels before contaminants can significantly accumulate and impair cooling efficiency. The control module schedules regular cleaning cycles that proactively maintain channel cleanliness.
Solution Approach 2:
The cleaning system operates continuously or periodically to maintain the cooling channels, ensuring that the useful action of cooling is never significantly interrupted. The system can clean while the cooling operation continues, maintaining continuous protective action against contaminant buildup.
2Productivity
If channelized water circulation is implemented through liquid cooling blocks, then heat dissipation is improved, but mineral deposit buildup reduces water flow quality and efficiency
Solution Approach 1:
The system uses the existing water circulation infrastructure to deliver cleaning solutions through the same channels that carry cooling water. The pump and control valve leverage the established fluid distribution network to perform self-maintenance without requiring separate access to the channels.
Solution Approach 2:
The system changes the chemical parameters of the circulating fluid by introducing cleaning solutions with different compositions (detergents, acids, bases) to dissolve and remove mineral deposits that have accumulated in the channels, thereby restoring water flow quality.
3Object-generated harmful factors
If cleaning cycles are performed on liquid cooling systems, then contaminant removal is achieved, but system downtime is required
Solution Approach 1:
The cleaning operation is designed to proceed continuously alongside the cooling operation. The system can circulate cleaning solutions through the channels while the cooling blocks remain in place, potentially maintaining cooling function or using isolated channel segments for cleaning without shutting down the entire system.
Solution Approach 2:
The system performs preliminary cleaning before contaminants significantly impact cooling performance, and can schedule cleaning during planned maintenance windows or use bypass configurations to clean channels while the system remains operational, minimizing disruption.

AI summary
A cleansing system and method for liquid-cooled rack-mounted processing assemblies are presented that incorporate a cleansing unit comprising a first liquid comprising an acidic detergent coupled a first fluid control structure, a second liquid comprising softened water fluidly-coupled a second fluid control structure, a third liquid comprising treated osmosed water fluidly-coupled a third fluid control structure, and a control module operably-coupled to the control structures and configured to select one of the first, second, or third liquids and define corresponding first, second, and third operational cleansing cycles and duration times. A forward fluid coupling section supplies the selected liquid to the processing assemblies and a return fluid coupling section receives the returned liquid from the processing assemblies for each of the defined operational cleansing cycles. In the event that liquid quality levels from the returning processing assemblies are unsatisfactory, a fourth operational cycle is defined and executed.
