Heat Management Device With Segmented Circuits For Simultaneous Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat management devices cannot simultaneously cool a battery and electrical apparatus using a radiator, as the heat medium flow is either for battery cooling or electrical apparatus cooling, not both simultaneously.
Innovation Solution
A heat management device with multiple interconnected heat circuits and control valves allows independent cooling of a battery and electrical apparatus by routing the heat medium through different circulation channels, enabling the heat exchanger to cool the battery and the radiator to cool the electrical apparatus without interfering flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heat medium flows through the radiator for battery cooling, then the battery can be cooled, but the electrical apparatus cannot be cooled simultaneously
Solution Approach 1:
The first heat circuit is segmented into multiple independent circulation channels: a first circulation channel for battery cooling (radiator passage), a second circulation channel for electrical apparatus cooling (electrical apparatus passage), and a third circulation channel for both (heat exchanger passage). This segmentation allows selective activation of cooling paths based on which component needs cooling, resolving the contradiction between battery cooling and electrical apparatus cooling capabilities.
2Temperature
If the heat medium flows through the heat exchanger for electrical apparatus cooling, then the electrical apparatus can be cooled, but the battery cannot be cooled simultaneously
Solution Approach 1:
The heat circuit is divided into separate circulation channels that can be independently controlled. The second circulation channel (electrical apparatus passage) provides dedicated cooling path for electrical apparatus, while the first circulation channel (radiator passage) remains available for battery cooling. Control valves enable selective routing of heat medium to the appropriate channel based on cooling requirements.
3Device complexity
If the heat medium circulates in a single channel, then the system structure is simple, but independent cooling of battery and electrical apparatus is not achieved
Solution Approach 1:
The heat circuit is segmented into multiple circulation channels (first, second, and third channels) with dedicated passages for battery and electrical apparatus cooling. Control valves are placed at key junctions to manage heat medium distribution across channels, enabling independent cooling control while maintaining a relatively integrated system structure.
Solution Approach 2:
The system employs dynamic control through control valves that can adjust heat medium flow distribution in real-time based on cooling demands. The valves enable the system to switch between different circulation modes (battery cooling mode, electrical apparatus cooling mode, or both simultaneously), providing adaptability without requiring completely separate static systems.
