Vehicular Thermal Management Selective Heat Transfer Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal management systems for vehicles lack flexibility in temperature adjustment for components like batteries, vehicle compartments, and reduction gear mechanisms, as they cannot directly switch and circulate coolants between these systems, limiting effective heat exchange and temperature control.
Innovation Solution
A thermal management system that includes a radiator, flow path groups, coolers, heaters, and pumps to switch and circulate heat transfer media between devices, allowing for selective circulation through bypass paths and interrupting heat exchange with outside air, enabling flexible temperature adjustment and efficient heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the battery, vehicle compartment, and reduction gear mechanism are connected to the first circulation circuit only, then heat exchange between these devices is enabled, but flexibility in temperature adjustment is limited
Solution Approach 1:
The circulation system is divided into two independent circulation circuits (first and second circuits), each capable of independently circulating heat transfer media. This segmentation allows different devices to be selectively connected to different circuits, enabling flexible temperature adjustment for the battery, vehicle compartment, and reduction gear mechanism without requiring complex reconfiguration of a single circuit system.
Solution Approach 2:
The heat transfer media circulation devices are designed to be switchable between the first and second circulation circuits. The same heat transfer media can serve multiple functions by circulating through different circuits depending on the thermal management needs of various devices, thereby improving adaptability without proportionally increasing system complexity.
2Productivity
If the second circulation circuit constantly allows coolant to pass through the exterior heat exchanger, then heat exchange with outside air is consistent, but heat exchange between multiple devices is ineffective
Solution Approach 1:
The circulation path of heat transfer media in the second circulation circuit is made dynamic and switchable. Instead of constantly passing through the exterior heat exchanger, the heat transfer media can be directed to different paths including heat exchange with multiple devices (battery, vehicle compartment, reduction gear mechanism). This dynamic switching enables effective heat exchange between multiple devices while maintaining the capability for external heat dissipation when needed.
Solution Approach 2:
The second circulation circuit acts as an intermediary system that can mediate heat exchange between multiple devices and the external environment. By controlling the circulation paths, heat can be transferred between devices through this intermediate circuit, improving overall heat exchange efficiency and flexibility.

AI summary
First circulation portions switch a flow of a heat transfer medium such that one of the heat transfer media for two systems selectively circulates through a radiator flow path or a first bypass flow path. Second circulation portions switch the flow of the heat transfer medium such that the heat transfer media for the two systems selectively circulate with respect to a second flow path group. The first circulation portions and the second circulation portions are adapted to switch the flow of the heat transfer medium so as to form a first circulation circuit for allowing the heat transfer medium to circulate among a first flow path group, the second flow path group, and a first pump, as well as a second circulation circuit for allowing the heat transfer medium to circulate among the first flow path group, the second flow path group, and a second pump.
