Here is my new BluRay build.
The box is made from aluminimum and acts as a heatink in itself. The aixiz module has a heatsink made from washers that have heat transfer grease in between them. These washers were then squeezed together before being glued to the aixiz.
There is also a washer glued to the smaller part of the aixiz. When the two halfs of the aixiz are screwed together, the washers press against the inside and outside of the metal box. The washers also press against the top and bottom of the box, with more heat transfer grease to aid the contact.
Basically the heatsink transfers heat to the box which aids more to the cooling of the diode.
I am running the diode at about 220mA (with a fresh 9v battery) giving about 135mW of power. Even with a new battery I can run the diode for about an hour before it gets too warm.
Topped off with a miniture key switch for security, I think it makes a neat little housing.
I'm going to do the same for my 250-300mW red burner next.
