Venting Tank Bypass Structure for Low-Pressure-Drop Degassing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing venting tanks in motor vehicle cooling systems face challenges in efficiently degassing heat transfer fluids while maintaining optimal circulation pressure, often resulting in increased pressure drops and potential system inefficiencies.
Innovation Solution
The proposed venting tank incorporates a bypass structure that separates inlet and outlet channels, allowing part of the heat transfer fluid to bypass the degassing space and flow directly to the outlet channel, thereby reducing pressure drops and ensuring efficient fluid circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat transfer fluid flows through the degassing space for thorough degassing, then degassing efficiency is improved, but pressure drop increases
Solution Approach 1:
The connecting pipe is segmented into inlet channel and outlet channel by the connecting pipe separator, creating distinct flow paths. The bypass structure further segments the flow into two streams: one through the degassing space and one bypassing it, allowing optimized degassing without excessive pressure drop
Solution Approach 2:
The bypass structure acts as an intermediary element that provides an alternative flow path. It mediates between the requirement for thorough degassing and the need to minimize pressure drop by allowing partial flow to bypass the degassing space while maintaining system pressure
2Productivity
If bypass structure is added to reduce pressure drop, then fluid circulation efficiency is improved, but device complexity increases
Solution Approach 1:
The bypass structure is merged with the existing connecting pipe structure, integrating the bypass function into the inlet/outlet connection rather than adding a completely separate component. This reduces overall system complexity while achieving the desired flow distribution
Solution Approach 2:
The connecting pipe separator and bypass structure serve multiple functions: they separate inlet and outlet channels, create the bypass flow path, and facilitate both degassing and pressure drop reduction within a single integrated assembly

Function Achieved in This Case
This design enhances the degassing efficiency of the heat transfer fluid while minimizing pressure drops in the cooling system, ensuring effective cooling and reducing operational costs through improved system integration and reduced part count.
Implementation Method 1
Part of a heat transfer fluid flowing in from the inlet channel does not pass through the degassing space but flows directly to the outlet channel via the bypass flow path
Implementation Method 2
The connecting pipe separator is provided in the connecting pipe and extends along a length direction of the connecting pipe to separate an inlet channel and an outlet channel in the connecting pipe

AI summary
The present disclosure provides a venting tank, a cooling system having the venting tank, and a motor vehicle having the cooling system. The venting tank comprises a tank body, a connecting pipe, a connecting pipe separator, and a bypass structure. The tank body has a degassing space therein. The connecting pipe is connected to the tank body and located outside the tank body. The connecting pipe separator is provided in the connecting pipe and extends along a length direction of the connecting pipe to separate an inlet channel and an outlet channel in the connecting pipe, wherein the inlet channel and the outlet channel are fluidly connected with the degassing space. The bypass structure forms a bypass flow path connecting the inlet channel with the outlet channel, wherein the bypass flow path is isolated from the degassing space. Part of a heat transfer fluid flowing in from the inlet channel is guided into the degassing space to be degassed, and the rest of the heat transfer fluid flowing in from the inlet channel does not pass through the degassing space but flows directly to the outlet channel via the bypass flow path.
