- Hirschvogel enters the EV heat sink market through Renault’s traction inverter project.
- The Flex Cooling Power Module improves cooling efficiency while reducing pressure loss.
Hirschvogel Group has secured a significant contract to supply its Flex Cooling Power Module for the “Power Electronic Box” initiative developed by Renault. The project focuses on a new generation of traction inverters designed for battery-electric vehicles. This award represents an important milestone for Hirschvogel as it expands beyond its traditional product portfolio and enters the growing market for thermal management solutions used in electric vehicle power electronics. The agreement highlights increasing demand for advanced cooling technologies that support the efficiency and reliability requirements of next-generation electric mobility systems.
The Hirschvogel Flex Cooling Power Module is based on a cold-forged heat sink concept featuring an innovative cooling structure. The design enables parallel fluid flow through individual fin stacks while incorporating additional structural elements that enhance thermal performance. By delivering more uniform cooling across semiconductors, the solution helps improve operational efficiency, minimize thermal stress, and support longer component service life. The technology is also designed to reduce thermal peaks that can impact system durability and performance in demanding operating conditions.
Key Benefits of the Flex Cooling Power Module
| Feature | Benefit |
|---|---|
| Parallel Fluid Flow Design | Consistent cooling across semiconductors |
| Cold-Forged Heat Sink | Enhanced thermal management performance |
| Reduced Thermal Peaks | Improved durability and service life |
| Lower Pressure Loss | Approximately half the pressure loss of conventional solutions |
The company has already completed the first series-equivalent part phases, demonstrating progress toward industrialization of the technology. Future production activities are scheduled to take place at Hirschvogel’s manufacturing facility in China, where series production is planned. The project reinforces the industry's focus on advanced thermal management systems as electric vehicle architectures become increasingly dependent on efficient power electronics and high-performance inverter technologies.
