Core Business & Product Portfolio

We specializes in a comprehensive product portfolio covering key automotive cooling and thermal management components, with all products designed to meet international automotive quality standards. Our core product range includes:

1. Aluminum Radiators：Aluminum core radiators with high-efficiency fin structures, available for passenger cars, commercial vehicles, off-road vehicles and classic car models. Featuring excellent heat dissipation performance and corrosion resistance, our radiators are engineered to optimize engine temperature control and prevent overheating in extreme driving conditions.

2. Aluminum Shrouds：Custom-molded air guide assemblies made of aluminum. Precision-matched with vehicle fan modules, they effectively direct airflow, improve cooling efficiency, reduce noise and protect internal cooling components, with customizable designs for different vehicle models.

3. Cooling Fans：Electric brush fans and brushless DC (BLDC) fans with low noise, high torque and long service life. Supporting multiple voltage specifications (12V/24V), our fans are widely used in engine cooling systems, battery cooling and other thermal management scenarios, ensuring stable performance in high-temperature and vibration environments.

4. Aluminum Tanks：Pressure-resistant fluid storage reservoirs for cooling systems, made of aluminum. Equipped with pressure relief valves and liquid level indicators, they maintain stable system pressure, facilitate coolant circulation and provide visual monitoring of coolant levels, compatible with both traditional fuel vehicles and new energy vehicles.

5. Intercoolers：Aluminum bar-and-plate or microchannel intercoolers for turbocharged engines. Designed to rapidly cool high-temperature compressed air, increasing air density and engine power output while reducing fuel consumption and emissions. Available in various specifications to match different engine displacements and turbocharger configurations.

6. Oil Coolers：Specialized thermal management components for engine oil, transmission oil and hydraulic oil cooling. Featuring efficient heat transfer structures and corrosion-resistant materials, they prevent oil overheating, ensure smooth operation of mechanical systems and extend the service life of engine and transmission components.

7. Condensers：Aluminum fin-and-tube condensers for vehicle air conditioning systems. Efficiently transfer heat from the refrigerant, realizing the condensation cycle of the air conditioning system, ensuring stable cooling performance and compatibility with various vehicle air conditioning models and refrigerant types.

8. Silicone Hoses：High-temperature and high-pressure resistant silicone rubber hoses, used for connecting cooling system components, air intake systems and oil pipelines. With excellent flexibility, heat resistance and aging resistance, they are ideal for replacing traditional rubber hoses, suitable for modified vehicles and high-performance engine applications.

Our products cover a full range of cooling system needs for traditional fuel vehicles, new energy vehicles, commercial vehicles and special vehicles. We provide both standardized mass-produced parts and customized solutions tailored to customer specific vehicle models, technical requirements and application scenarios.
