Fujitsu is at least several thousand times the size of Acebeam and Olight. They have a huge amount of resources and thousands of engineers to perform research and development for products that sell in the millions. In comparison, Acebeam probably has a handful of engineers that develop products that sell in the hundreds or maybe thousands. For a company the size of Fujitsu to develop this capability is an achievement worth noting but for a company like Acebeam to successfully develop this feature is remarkably impressive.
I just hope Acebeam don’t end up failing like Olight. Would be funny if a bargain brand like Astrolux end up as the only one that can make an actively cooled flashlight.
I think most of the problem Acebeam is encountering have to do with making the fan water resistant, but they don’t have to if they used a separated motor and propeller assembly with a waterproof bearing in the shaft. Motor remains isolated and dry in the driver bay.
They’re probably limiting themselves by using regular computer fans where the motor and controller is inside the propeller, this makes the whole assembly exposed the elements.
Im still curious how good or bad the battery life on total runtime will be, it cant be very high if its gonna use 8x18650 batteries 3000mah… Compared to whats out there they cant really do magic…
I can’t think of something right, and I didn’t say anything about a device that’s being submerged.
There are really thousands different ‘devices’ that are using fans and pretty sure that there are more than you know that are ‘IP’ rated.
Really, a fan is nothing more than an electronic motor and those can easily work underwater. The only thing an electronic motor needs is a changing magnetic field and water doesn’t change that. All the other electronics can be even extern or coated to make it waterproof. The main problem is making a waterproof connection to the inside for the wires.
Yes a waterproof fan is probably expensive but not impossible.
