Partitioned Liquid Tank Layout for Bubble-Free Pump Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid level fluctuations and bubble formation in liquid storage tanks of cooling systems affect pump reliability, making accurate liquid level and pressure measurement difficult.
Innovation Solution
A liquid storage tank with a partition dividing the space into two compartments, where the smaller compartment communicates with the inlet and the larger with the outlet, and includes openings to control liquid flow, accompanied by a sensor for precise level and pressure measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If water flows directly into the liquid storage tank, then the liquid storage tank can be simply structured, but the liquid level fluctuates and bubbles form affecting pump reliability
Solution Approach 1:
The liquid storage tank is divided into two spaces by a partition: a first space for receiving liquid and a second space for storing liquid. The partition has openings that control liquid flow from the first space to the second space, preventing direct flow into the tank. This segmentation suppresses liquid level fluctuation and bubble formation, improving pump reliability while maintaining reasonable structural complexity.
2Device complexity
If water flows directly into the liquid storage tank, then the device complexity is reduced, but measurement precision of liquid level and pressure deteriorates
Solution Approach 1:
By dividing the tank into two spaces with a partition containing controlled openings, the liquid flow is regulated to minimize turbulence and fluctuation. This creates a more stable liquid level in the second space, enabling accurate placement of sensors for precise liquid level and pressure measurement.
3Measurement precision
If a partition with openings is added to the liquid storage tank, then liquid level fluctuation is suppressed and measurement precision is improved, but device complexity increases
Solution Approach 1:
The partition divides the tank into functional zones (first space for inlet, second space for outlet and measurement) with controlled openings. This segmentation achieves stable liquid level and accurate measurement while keeping the overall structure integrated and manageable, balancing complexity with performance improvement.
4Device complexity
If water flows directly into the liquid storage tank, then the liquid storage tank can be simply structured, but bubbles form impacting the sidewalls and reducing pump reliability
Solution Approach 1:
The partition with controlled openings creates a staged liquid flow path from the first space to the second space. This segmentation allows liquid to settle and release air bubbles progressively rather than flowing directly into the tank, reducing bubble formation and their impact on sidewalls and pump reliability.

AI summary
A liquid supply device includes a liquid storage tank and at least one liquid pipe. The liquid storage tank includes a housing and a partition. The housing has an accommodation space, an inlet and at least one outlet. The partition is disposed in the accommodation space and divides the accommodation space into a first space and a second space. The inlet communicates with the first space, and the outlet communicates with the second space. The second space is of greater volume than the first space. The partition has at least two openings through which the first space and the second space communicate with each other. The liquid pipe is connected to at least one of the inlet and the outlet of the housing.
