Optimize Thermal Management with EPDM Cooling Hoses & Connectors

IntroductionIn a modern electric vehicle, the Thermal Management System (TMS) is the heart of efficiency. It actively cools the battery during charging, warms it in winter, and cools the e-motor. This complex network of "plumbing" requires meters of flexible tubing and reliable connectors.

The industry is moving away from heavy metal pipes to lightweight EPDM Rubber Hoses and Plastic Quick Connectors.

1. The Complexity of EV Plumbing

An EV thermal system is far more complex than a standard radiator loop. It involves multi-way valves, heat pumps, and chillers.

• The Risk: More connections mean more potential leak points.

• The Solution: Precision-molded EPDM hoses with integrated quick-connect ends reduce assembly time and leak risks.

2. Why EPDM is the King of Coolant

For transporting glycol-based coolants, Peroxide-Cured EPDM is the material of choice.

• Heat Resistance: Withstands up to 135°C continuous use.

• Chemical Resistance: Impervious to modern coolants (OAT/HOAT) and electrochemical degradation (ECD), which eats away at lesser rubbers.

3. Lightweighting with Rubber

Replacing rigid aluminum pipes with flexible EPDM hoses allows for easier routing through the tight spaces of an EV "frunk" or battery tunnel. It also decouples vibration, preventing stress fractures in the cooling loop.

4. Conclusion

As EVs push for faster charging (which generates more heat), the reliability of the cooling loop is paramount. Fuqiang delivers extruded and molded EPDM solutions that keep your thermal system leak-free for the life of the vehicle.

Fuqiang manufactures a wide range of extruded rubber hoses and molded coolant pipes for automotive thermal management systems.

FAQ

• Q: What is electrochemical degradation (ECD)?

• A: It is a process where the coolant fluid and rubber react electrically, causing the hose to crack from the inside out. Our EPDM is ECD-resistant.

• Q: Can you make pre-formed hoses?

• A: Yes, we can mold hoses into complex 3D shapes to fit specific engine bay geometries.
