Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a single-loop cooling system is used for heat dissipation, then heat dissipation efficiency is improved, but thermal insulation capability deteriorates
Solution Approach 1:
The single cooling loop is segmented into two independent loops: a first loop for heat dissipation and a second loop for thermal insulation. This allows the system to independently control heat dissipation and thermal insulation functions, resolving the contradiction between heat dissipation efficiency and thermal insulation capability
Solution Approach 2:
The system dynamically switches between different operational modes by controlling solenoid valves to connect or disconnect the first and second loops. This dynamic configuration allows the system to adapt to varying thermal management requirements, achieving both effective heat dissipation when needed and thermal insulation when needed
2Adaptability or versatility
If thermal insulation measures are applied, then thermal insulation capability is improved, but heat dissipation efficiency deteriorates
Solution Approach 1:
The cooling system is divided into two separate loops with independent thermal insulation structures. The second loop is specifically designed for thermal insulation and can be activated independently without affecting the heat dissipation function of the first loop
Solution Approach 2:
Thermal insulation structures are introduced as intermediary elements between the cooling system and the external environment. These structures can be selectively activated to provide thermal insulation when needed, while the heat dissipation loop remains unaffected
3Adaptability or versatility
If dual-loop system with solenoid valves is implemented, then adaptability for both heat dissipation and thermal insulation is improved, but device complexity increases
Solution Approach 1:
The dual-loop system is designed with shared components and control mechanisms that can serve multiple functions. The solenoid valves and control unit can manage both heat dissipation and thermal insulation operations, reducing the overall system complexity despite the dual-loop configuration
Solution Approach 2:
The first loop and second loop are merged into a unified thermal management system with common control logic and integrated structure. This merging allows the system to achieve high adaptability while minimizing the increase in device complexity through shared resources

AI summary
Embodiments of this application disclose a thermal management apparatus, a thermal management system, and a new energy vehicle, to perform thermal management on an electronic device and meet both a heat dissipation requirement and a thermal insulation requirement of the electronic device. The thermal management apparatus includes a first loop in which a first solenoid valve, a first liquid cooling plate, a second solenoid valve, and a second liquid cooling plate are sequentially connected in series, and a thermal insulation structure. The second liquid cooling plate, the thermal insulation structure, and the first liquid cooling plate are sequentially stacked. The first liquid cooling plate can perform heat transfer with the electronic device. When the first solenoid valve and the second solenoid valve are closed, the first liquid cooling plate communicates with the second liquid cooling plate. When the first solenoid valve and the second solenoid valve are open, the first liquid cooling plate and the second liquid cooling plate are disconnected.
