Example of Wide Temperature Range Fan | 066 | What is a fan that can operate for a long time even in high temperature environments?

Problem

"Commercial projectors" are now widely used in conference rooms and halls. In recent years, high-brightness models using LEDs or lasers are becoming mainstream. Compared to conventional products, these offer various advantages such as a long life, no maintenance, and high color reproduction, and are becoming increasingly popular.

New projector development requires fan that can operate for long periods even at high temperatures

Company A manufactures and sells professional-use filming and audio equipment. The company has recently been working on developing a professional-use projector equipped with solid-state light sources such as LEDs and lasers. Director D of the R&D department at Company A says the following:

"We had several technical challenges in the development. One of them was the cooling system for the laser-equipped model we were developing.
Although laser light sources generate relatively little heat, the inside of the projector can become extremely hot when used for long periods of time. Laser light sources are sensitive to heat, and heat that accumulates inside can cause malfunctions, so efficient cooling is essential. For this reason, it was essential that the fan be able to operate for long periods of time even in high-temperature environments.

In addition, because commercial projectors project images from a greater distance than normal, even the slightest vibration can affect the image. Therefore, stricter vibration-reducing performance was required. Mr. D and his team searched for a fan that could meet these requirements and began to gather information.

"The model we were developing was a stepping stone to expanding our business in commercial projectors. The entire staff was in agreement that we would not compromise on the technology in order to create a product that would meet the needs of our customers." (Mr. D)

You need a fan that can operate for long periods of time even in high temperature environments.
I want to reduce fan vibration as much as possible.

Solution

Expected life of 40,000 hours at +85℃! Industry-leading temperature resistance

Mr. D continued to gather information and contacted SANYO DENKI CO., LTD.. When he discussed his problem, they suggested the "San Ace Wide Temperature Range Fan," and he found a clue to the solution.
"What attracted me to this fan was that it has an expected lifespan of 40,000 hours(*) even in a high-temperature environment of +85°C. This is apparently the best temperature resistance in the industry. With 40,000 hours, there's no need to worry about fan maintenance." (Mr. D)

* L10: Survival rate 90% at 85℃, rated voltage, continuous operation, in free air

Satisfied with the proposal, Mr. D ordered a sample and began evaluating the actual product.

"When we evaluated it, we found that there were no problems with vibration performance, which we had been concerned about. The frame is made of aluminum, which gives it great rigidity and reduces vibration, which also led to high praise. They also provided detailed support and customized the connectors and lead wires to suit the device specifications. We were very surprised by this flexible response, which is not available from other manufacturers." (Mr. D)

Having confirmed that the requirements were fully met, Company A decided to adopt SANYO DENKI CO., LTD. 's "San Ace Wide Temperature Range Fan."

"We were able to successfully complete the development of the new model. We are considering using the same fan not only in this product, but also in our next product. We would like to continue to consult with SANYO DENKI CO., LTD. on various matters." (Mr. D)
