AI Technical Summary

Technical Problem

Traditional vehicle thermal management systems are difficult to be compatible with R290 (propane), resulting in poor compatibility, high adaptation development costs, and R290 (propane) leakage can easily enter the passenger compartment, affecting the safety of use.

Method used

A vehicle thermal management system was designed to cool the passenger compartment through a water-cooled core and isolate the flammable and explosive R290 (propane) from the heat exchange medium. The system employs a multi-way valve and multiple cooling circuit designs to ensure system compatibility and safety.

Benefits of technology

It ensures the cooling performance of the crew compartment, reduces adaptation development costs, and improves the safety of the thermal management system by isolating the risk of R290 (propane) leakage.
