Rotatable Dip Tube Degassing Tank for Coolant Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing degassing tanks for motor vehicle cooling systems lack a simple and effective means to control the flow of liquids, leading to inefficient gas removal from the heat transfer fluid.
Innovation Solution
A degassing tank with a movable dip tube that can be rotated between different positions to either allow or block fluid communication between the inlets and the lower portion of the tank, utilizing a partially circumferential recess and radial hole for fluid passage and obstruction, allowing for controlled fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dip tube is made movable to control fluid flow, then the control capability is improved, but the device complexity increases
Solution Approach 1:
The dip tube is designed to be movable rather than fixed, allowing it to rotate between a first position (providing fluid communication) and a second position (blocking fluid communication). This dynamic configuration enables flow control without requiring separate valves or complex mechanisms.
Solution Approach 2:
The dip tube serves multiple functions: it acts as both a fluid conduit when in the first position and a flow blocking element when in the second position. This multi-functionality reduces the need for additional components, thereby controlling complexity while improving operation capability.
2Ease of operation
If the dip tube is made rotatable with recess and hole structure, then the fluid flow control is improved, but the manufacturing complexity increases
Solution Approach 1:
The recess and radial hole are integrated directly into the dip tube structure, combining the flow passage function and the blocking function into a single component. This merging reduces the number of parts and assembly steps, offsetting the increased manufacturing complexity of the recess-hole structure.
Solution Approach 2:
The dip tube with its recess and radial hole is received within the valve housing, creating a nested structure. This nesting arrangement allows the complex dip tube structure to be integrated into the existing housing, minimizing additional manufacturing complexity.
