Solution Overview
Problem
Conventional reversing devices for cooling liquids in hybrid and electric vehicles experience degraded inner sealing performance over time, leading to inefficiencies in thermal management systems.
Innovation Solution
A flow rate control device with a housing and valve core design that includes a sealing contact portion and a housing contact portion, which are dynamically sealed against liquid, and a transmission element to control the flow rate by communicating through a circulation channel, ensuring reliable sealing and flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional reversing device is used for cooling liquid circulation, then the device can reverse flow direction, but the inner sealing performance degrades over time
Solution Approach 1:
The housing is divided into an outer housing and an inner housing that are relatively fixed to each other. The valve core is segmented with a main body portion and a sealing contact portion. This segmentation allows the sealing contact portion to always contact the housing contact portion during relative movement, maintaining stable sealing performance over time without degradation.
2Ease of operation
If the valve core moves relative to the housing to control flow, then flow rate control is achieved, but sealing performance may deteriorate
Solution Approach 1:
The sealing contact portion of the valve core is designed to always contact the housing contact portion during relative movement automatically. This self-service sealing mechanism ensures that sealing is maintained throughout the entire range of motion without requiring external intervention or complex sealing systems, allowing easy flow control while maintaining reliable sealing.

AI summary
A flow control device for a heat exchange system. The device includes a housing, a valve core and a transmission element. The housing is formed with an accommodating portion, a first port and a second port, the valve core being at least partially accommodated in the accommodating portion. The housing includes fixing elements and an outer housing, the fixing elements being located on a circumferential inner side of the outer housing, the outer housing and the fixing elements are arranged in a relatively sealing manner, and the valve core and the fixing elements are arranged in a relatively sealing manner. The valve core at least has a first flowing passage. The transmission element drives the valve core to open or close at least one of the first and second ports, thereby improving an internal sealing performance of the product.
