Water Cooling Pump Air Separation via Angular Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In water cooling systems for computers, air can enter the pipeline when the water level is insufficient, leading to pump speed reduction or blockages, which affects the system's stability and reliability.
Innovation Solution
The integration of a water storage assembly with a liquid storage chamber and protrusive tube ends creates an angular space that separates air from the working fluid, preventing air from entering the pump and reducing the likelihood of idling or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water level in the chamber is insufficient or low, then the pump may extract air causing speed reduction or blocks, but adding more water storage increases the complexity of the system structure
Solution Approach 1:
The liquid storage chamber is merged with the pump body to form an integrated structure. The pump housing simultaneously serves as the liquid storage chamber, eliminating the need for a separate external reservoir. This integration reduces the number of components while ensuring the pump has sufficient liquid storage to prevent air extraction during operation.
Solution Approach 2:
The liquid guide is nested within the liquid storage chamber, with its end extending into the chamber. The liquid guide structure is positioned such that it is contained within the pump body's internal space, maximizing space utilization without increasing external dimensions or structural complexity.
2Reliability
If air enters the pipeline and pump, then pump blocks and idling/damage occur, but creating air separation structures increases device complexity
Solution Approach 1:
The liquid guide is positioned asymmetrically within the liquid storage chamber, with its end extending specifically toward one side of the chamber. This asymmetric positioning creates an angular space between the liquid guide and the chamber wall, forming a natural air pocket that separates air from the liquid flow path entering the pump.
Solution Approach 2:
The angular space formed by the liquid guide positioning acts as an intermediary air separation zone. This space serves as a buffer that traps air bubbles before they can enter the pump, preventing air-related damage without requiring complex mechanical air separation devices.
3Reliability
If the protrusive tube end is positioned close to the inner wall, then air separation is effective, but the liquid flow path may be restricted
Solution Approach 1:
The liquid guide end is positioned to extend locally into the liquid storage chamber, creating a localized angular space for air separation. The liquid guide maintains sufficient diameter and length to ensure adequate liquid flow through it, while its specific positioning creates the air pocket only in the angular space between the guide and chamber wall, not restricting the main flow path.
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
This design enhances the operational stability and service life of the water cooling system by preventing air from entering the pump, thus maintaining consistent performance.
Implementation Method 1
when the working fluid is insufficient or at a low level and both the working fluid and air enter the liquid storage chamber and pass the liquid guide, air upward stays in the angular space to be separated from the working fluid as the working fluid covering the protrusive tube end
