Segmented Fluid Management Valve Block for Heat Loss Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid management systems experience harmful heat loss due to close proximity of valve cores in thermal management systems, leading to inefficient heat exchange and performance interference.
Innovation Solution
A fluid management device design featuring hermetically connected block portions with gaps between them, where valve core assemblies are partially located in a control assembly's cavity and mounting channels, reducing heat transfer and minimizing heat loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple valve cores are installed in a same valve seat and communicated through channels inside the valve seat, then the space occupied by valves is reduced, but heat transfer between fluid in different channels increases causing harmful heat loss
Solution Approach 1:
The patent divides the valve body into multiple independent block portions, each housing a valve core assembly. These block portions are arranged adjacent to each other but separated by gaps, allowing each valve core to operate independently while maintaining compact overall structure. This segmentation reduces heat transfer between adjacent valve cores compared to a fully integrated valve seat design.
2Adaptability or versatility
If multiple valve cores are respectively installed in adjacent valve body portions of a flow channel plate, then valve functionality is distributed, but heat transfer between fluid in adjacent valve body portions increases through the flow channel plate causing interference
Solution Approach 1:
The valve body is segmented into multiple independent block portions that can be manufactured separately and then assembled. Each block portion contains its own valve core assembly and flow channels, enabling independent functionality while reducing thermal interference through the intentional gaps between blocks.
Solution Approach 2:
The gaps between adjacent block portions act as thermal barriers or intermediaries that reduce heat transfer between neighboring valve assemblies. These gaps break the continuous thermal path that would otherwise exist through a solid flow channel plate, thereby reducing harmful heat loss.
3Volume of moving object
If valve cores are positioned close to each other, then device compactness is improved, but heat conduction between fluid in different channels increases causing harmful heat loss
Solution Approach 1:
The compact design is achieved by segmenting the valve body into multiple small block portions arranged in a compact configuration. The gaps between these segments provide thermal isolation while maintaining overall device compactness, as the segmented structure allows for optimized spatial arrangement.

Function Achieved in This Case
The design effectively reduces harmful heat loss and improves system performance by minimizing heat transfer between adjacent components, enhancing the efficiency of fluid management.
Implementation Method 1
A gap is formed between two adjacent body portions. The separation between the body portions reduces the possibility of heat transfer, thereby reducing harmful heat loss of the fluid management device.

AI summary
A fluid management device includes a control assembly, at least two block portions, and at least two valve core assemblies. The at least two block portions are hermetically connected to a same control assembly. The valve core assemblies are electrically connected to the control assembly. Each block portion includes a body portion. The body portion defines a mounting channel. A portion of the valve core assembly is located in an inner cavity of the control assembly, and another portion is located in the mounting channel. A gap is formed between two adjacent body portions for separating the body portions so as to reduce the possibility of heat transfer, thereby reducing harmful heat loss of the fluid management device.
