Solution Overview
Problem
Existing heat pump systems in vehicle thermal management have a low battery heat exchange rate, leading to slow temperature attainment for battery modules and reduced operating stability.
Innovation Solution
A thermal management system with a high battery heat exchange rate, featuring a compressor, a first heat exchanger, and a heat exchange assembly with parallel first and second heat exchange plates that directly contact the battery module for efficient heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional heat pump system is used, then the system structure is simple, but the battery heat exchange rate is low and the battery cannot quickly reach appropriate operating temperature
Solution Approach 1:
The heat exchange assembly is segmented into multiple independent heat exchange plates (first heat exchange plate, second heat exchange plate, third heat exchange plate) that can be independently arranged and configured. Each plate can contact different surfaces of the battery module, allowing the system to achieve high heat exchange rates through distributed thermal contact points rather than a single complex heat exchange unit.
2Productivity
If heat exchange plates are arranged to directly contact the battery module, then heat exchange efficiency is improved, but the arrangement complexity increases
Solution Approach 1:
Different heat exchange plates are positioned to contact different local surfaces of the battery module (first plate contacts first surface, second plate contacts second surface, third plate contacts third surface). This local quality approach allows each plate to be optimized for its specific position while maintaining overall system simplicity, as each plate performs a dedicated function rather than requiring a complex integrated design.

Function Achieved in This Case
The system enables the battery module to quickly reach an appropriate operating temperature, improving its stability and the overall performance of the thermal management system.
Implementation Method 1
the first heat exchange plate and the second heat exchange plate are arranged/disposed to exchange heat with the battery module, and may be in direct contact with different end surfaces of the battery module for heat exchange

AI summary
A thermal management system includes a compressor, a first heat exchanger, and a heat exchange assembly. An exhaust port of the compressor is connected to the heat exchange assembly, a first port of the first heat exchanger is connected to an air inlet of the compressor, and a second port of the first heat exchanger is connected to the heat exchange assembly. The heat exchange assembly includes a first heat exchange plate and a second heat exchange plate which are disposed in parallel, and each of the first heat exchange plate and the second heat exchange plate is configured for adjusting the temperature of a battery module.
