The challenge
Make the cooling of the projector more powerful.
The solution
Due to reuse of the same cooling device in more and more powerful projectors, the existing cooling became under dimensioned. By selecting new radiator technology, a much more performing fan and by optimizing the use of space, I managed to divide the delta T in 2.
Get twice as much for the same price!
Much fewer mechanical components compensate completely the higher prices of fan, filter and radiator, to great satisfaction of the end user.
