Heat, especially motor speed (relative) are even more so when not high, and (when motor speed is high, integrated air flow is big, flows through motor
What throughput still can be protected, now radiating effect is preferable).And if reduce air channel bore and flow through motor gas to be lifted
The ratio and flow velocity of stream, then when needing Wind Volume (now motor is high rotating speed), be easy for causing air-flow by bore not
Foot.And in this programme, a circle radiating regulation batten has been encircled a city in one " wind gathering air channel ", is then formed between adjacent heat radiation adjustable plate
