The thermal management system of new energy vehicles is transforming from distributed to integrated and integrated, driving the collaborative upgrade of core components such as through-flow fans, PTC heaters, and DC motors to meet the needs of vehicle energy efficiency improvement and space optimization. Traditional distributed thermal management systems have many components, large space occupation, and low energy utilization, which are difficult to match the requirements of new energy vehicles for cruising range and spatial layout.

The integrated thermal management system can realize the collaborative control of cockpit cooling, battery cooling, motor heat dissipation and other functions, effectively improving energy utilization. This trend has promoted the development of related core components in the direction of miniaturization, lightweight and high integration: the through-flow fan adopts a compact design to meet the space requirements of the integrated air conditioning module; PTC heaters are deeply integrated with battery thermal management systems to improve energy utilization efficiency under low temperature conditions. DC motors provide stable power support for integrated systems through high-efficiency drive technology. Through cross-field collaborative research and development, enterprises strengthen the adaptability between components and promote the overall performance improvement of thermal management systems. With the transformation of new energy vehicles to high-end and intelligent, the penetration rate of integrated thermal management systems will continue to increase, driving the coordinated development of the upstream core component industry.
