January 15, 2025 —— With the rapid growth of the electric vehicle market, the IGBT heatsink market is welcoming unprecedented opportunities. According to statistics and forecasts by QYR (QYResearch), the global new energy vehicle board IGBT module heatsink market sales reached $261 million in 2023, and is expected to reach $1.038 billion by 2030, with an annual compound growth rate (CAGR) of 22.1%.

Market Demand Growth

IGBT, as a core component in electric vehicles, is mainly used in motor controllers, on-board chargers (OBC), vehicle air conditioning, and charging piles. With the rapid growth of the new energy vehicle market, the demand for IGBT is also increasing significantly, which directly drives the expansion of the IGBT heatsink market.

Technological Innovations Assist

To meet the heat dissipation requirements of IGBT under high power density and high operating speed, heat dissipation technologies are continuously innovating. For example, the application of graphene-based films (GBF) has significantly improved the heat dissipation performance of IGBT. Studies have shown that GBF, used as a thermal distributor placed on the chip surface, can improve the lateral heat dissipation of local hot spots and has a high heat flux density, which can significantly reduce the highest temperature on the chip surface. In addition, micro-meter thick graphene-based films have better heat dissipation performance than nano-meter thick graphene-based films.

Application Cases

In the electric vehicle charging system, the design of IGBT heatsinks is crucial. A study analyzed the performance of 1 kW asynchronous buck converter (ASBC) and synchronous buck converter (SBC) in electric vehicle battery charging. The experimental results showed that the designed heatsink could maintain the temperature of the IGBT at 36.2°C and 42.5°C respectively, ensuring the thermal stability of the system.

Future Outlook

As IGBT technology continues to develop, its power density and operating speed will further increase, which will put higher demands on heat dissipation technologies. In the future, the IGBT heatsink market will continue to grow rapidly, and technological innovations will continuously optimize heat dissipation solutions to meet the development needs of the electric vehicle industry.

In summary, the IGBT heatsink market, driven by the electric vehicle industry, is welcoming a broad development prospect. Technological innovations not only enhance the performance of heatsinks but also provide strong guarantees for the efficient operation of electric vehicles.
