Electric valve and thermal management assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In refrigeration systems such as automobile air conditioning and battery cooling systems, electric valves used for flow rate control are heavy, posing a challenge for weight reduction while maintaining accuracy and functionality.
Innovation Solution
The design of an electric valve with a valve body comprising a first and second portion, where the second portion is positioned below the first, and a cover body connected to the first portion, allowing for reduced weight by optimizing the structural configuration and placement of components, including a circuit board and sensor, within a thermal management assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the electric valve uses a traditional complete valve body structure, then the structural strength and sealing performance are ensured, but the weight of the electric valve increases
Solution Approach 1:
The valve body is divided into a first portion and a second portion, where the first portion is connected to the cover body and the second portion is removed or reduced. This segmentation allows the electric valve to maintain structural strength at the connection interface while significantly reducing the overall weight by eliminating unnecessary valve body material in the second portion.
2Weight of moving object
If the electric valve uses a traditional complete valve body structure, then the sealing performance is ensured, but the weight of the electric valve increases
Solution Approach 1:
The second portion of the valve body is extracted or removed from the traditional complete valve body structure. The sealing function is maintained through the cover body that is fixedly connected to the first portion of the valve body, eliminating unnecessary material while preserving the essential sealing performance required for reliable operation.
3Weight of moving object
If the electric valve reduces the valve body weight, then the overall system weight decreases, but the structural integrity may be compromised
Solution Approach 1:
By segmenting the valve body into first and second portions and selectively removing the second portion, the design maintains structural integrity at the critical connection interface (first portion connected to cover body) while reducing overall weight. The segmentation ensures that remaining structure is optimized for its specific function rather than over-engineered for the entire valve body.
