Summer is a season of hair removal and there are many types of hair removal machine.On the market, the 808 diode laser hair removal machine is the best choice.But the 808nm type also has a big difference.So how do we choose a good 808 hair removal machine?
The 808 diode laser hair removal machine on the market can be divided into three kinds: no channel, macro channel, and micro channel.
1.What is micro channel?
Micro channel is a kind of diode laser bar heat disappation way. It is like a man lying dowm on the ice with full body surface to cooling down.You can see from the following micro channel heat-sink.There are several layers of holes to make the heat disappation.So with micro channel way, the diode laser stack can work well and no any burning problems. Usually we imported this kind of heat sink from Germany with good quality and the water way with high precision.But also some China supplier used cheap quality immitated micro channel.And feedback not good.
2.What is macro channel？
Macro channel is another way for diode laser bar heat-disappation. It is like a man standing on the ice with his feet surface to cooling down. It can not be compared with micro channel cooling stack. But also this kind of diode laser stack with some holes inside for water recycling. You see diode laser bar are mounted on a big stack of metal with covered copper directly. They can not full contact water way 100%. So the water cooling is not easy. Also this kind of stack calls for high profession to do the holes for cooling too especially for the water way design. Most of China supplier so far can not meet the demand to design a nice quality macro channel heat- sink to work more than 1.5 millions shots.
3.What’s the difference of micro channel and macro channel diode laser bar?
Difference between Micro channel and Macro channel -Technical parameter
1.Macro channel heatsink is made in China.Micro channel cooler is made in Germany with precise technique to make sure the best cooling.
2.There is only one big waterway through the Macro channel diode stack. So the laser bars are not all covered by water cooling. There is 1/3 part of the bar can contact the cooling water directly and other 2/3 part cooling can not. For micro channel cooling, there are 3 layers of water road, all bar lies on this water road directly, so micro channel cooling is better. It can protect bar from burning.
Difference between Micro channel and Macro channel -Customer feedback
At first ,Macro bar is burnt easily because the cooling is bad.
Compared with other Chinese company,90% of Chinese company are using macro channel bar. Therefore their machine is with bad cooling,low energy.Customer show their feedback that their handle are easily burnt.
*The big difference is about the cooling,the cooling for micro channel is better.
*The other point is the output power,micro channel is higher than macro channel.
*The last and key points is the life time.
The life time for macro channel is only2.000.000-3.000.000 shots. For micro channel the life time can reach more than 40.000.000 shots.
Some diode laser combined with real and fake Micro channel bar. The power of that is lower than the real 6 pieces of Micro channel bars. You can see in the picture.
