In terms of core technological innovation, the company focused on the technical pain points of automotive defrosting, heating, and cooling systems, conducting targeted R&D. In the defrosting system, the R&D team optimized air duct design and fan selection to improve the uniformity and velocity of defrosting airflow, shortening defrosting time and ensuring safe operation in low-temperature environments. In the heating system, high-efficiency heating elements and intelligent temperature control technology were employed to achieve rapid heating and precise temperature control, enhancing driving comfort while reducing energy consumption. In the cooling system, improvements to compressor matching and condenser design increased cooling efficiency and enhanced the system's cooling capacity in high-temperature environments.

Product upgrades are a direct manifestation of technological innovation. To meet the needs of different vehicle types, Cangzhou Xinwang has comprehensively upgraded its existing products. For the heating and air conditioning system for buses, while maintaining existing performance, lightweight design and noise reduction technology were employed to reduce product weight and operating noise, thereby improving passenger comfort. To address the harsh operating environment of construction vehicles, the radiator has been reinforced with high-strength materials and corrosion-resistant coatings, improving its vibration and corrosion resistance and extending its service life.

In the field of thermal management for new energy vehicles, the company is also actively developing technology and product upgrades. Targeting the characteristics of electric vehicles, it has developed a highly efficient electric heating system and intelligent thermal management control strategy, enabling coordinated thermal management of the battery, motor, and electronic control system, thereby improving the vehicle's range and operational safety. Furthermore, the company has optimized the integrated design of the air conditioning and refrigeration system and the battery cooling system, enhancing system energy efficiency and adapting to the unique thermal management requirements of new energy vehicles.

To promote continuous technological innovation and product upgrades, the company has established a comprehensive R&D management mechanism. A dedicated R&D fund is established to encourage R&D personnel to engage in technological innovation. An industry-university-research collaboration mechanism has been established to facilitate technical exchanges and collaboration with universities and research institutions, introducing advanced technologies and talent to enhance the company's R&D capabilities. Furthermore, the company closely monitors industry technology trends and market demand, adjusting R&D directions in a timely manner to ensure that technological innovation and product upgrades keep pace with market demand.

Through continuous core technology innovation and product upgrades, Cangzhou Xinwang has continuously improved its product performance and significantly enhanced its market competitiveness. This has earned it a strong reputation in both domestic and international markets, providing strong momentum for the company's continued development.
