Cooling fan makers see an opportunity in the auto industry

Cooling fan manufacturers are looking forward to the opportunities brought by autonomous driving and 5G technology, and Sunonwealth motor industry expects that camera modules for cars and autonomous driving systems will bring the demand for cooling solutions.

As the notebook market matures, cooling solution vendors are always looking for new opportunities from other markets.Heat pipe manufacturers' steam room solutions have infiltrated smartphone applications, while cooling fan makers are targeting cars and data centers because the noise generated by the cooling fan's vibration is not ideal for smartphones.

Sunonwealth's automotive application revenue grew 36% in the first three quarters of 2019 from the same period last year, primarily due to increased demand for air conditioning temperature sensors and fans for wireless charging pads and car seats.

The company is more optimistic about the outlook for 2020, predicting car enthusiasts' contribution to revenues will rise from 6 per cent today to more than 10 per cent.

Sunonwealth noted that demand for cooling fans in the auto industry is largely due to accelerated adoption of electronics in cars.Demand is expected to fall sharply in the coming years as cars move toward autonomous driving.

Sources from the upstream supply chain say that for a four-stage autonomous vehicle, all its computing components and camera modules may require 8-11 cooling fans.

As 5G will become the new standard for automotive communications systems, the need to cool those systems will soar.In addition to Sunonwealth, taiwan-based Delta Electronics, Yen Sun Technology and Power Logic have also been planning these business opportunities, which are expected to take off in 2020.

Yen Sun recently opened a new factory in China that will start mass production by the end of 2019, with a capacity of one million vehicles per month.The capacity will be used mainly to supply Chinese customers in its automotive and industrial markets.
