Lighting Peltier cooling?

[Rapha El]

So the cooler our COBs run the more efficient they are.. has anybody tried strapping one to a peltier element and that one to a big heatsink to see what happens?

Would the energy you put in the cooler be less or equal than what you'd save? Since you're still putting in the same energy your photon rate rises.. good cheat to get more out of your equipment?

Be interesting to see, give it a shot

I've pondered this idea for awhile..... I've considered it as an addition to my water cooled cob set up but can't quite justify the means......

You can stack peltiers to amplify the effects but is a boost in lumens worth the effeciency being penalized by the additional power draw?

Very good idea! Wonder how practical it is though, but yeah dude, great insight

Peltier´s are very inefficient so it will be a total waste of energy.
If you want to cool more use water cooling.
A total nerd could put a water tank in a fridge and use 1 deg c cold water for water cooling.

Not sure what you mean by "stacking". While one side of a peltier will be cold I can assure you that you can nearly boil water on the other side of the peltier chip. Again I don't understand how you would stack them.

Always keep in mind that EVERY watt put into a grow space is energy converted into heat, regardless of whether that watt is being used to produce/provide light, air movement, water movement, cooling, a digital termometer(ok sure, that's nitpicking.....!), timers, thermostats, etc.....

As mentioned, Peltier cooling is very inefficient and how to remove the heat from the hot side of the chip without adding more energy = heat in the form of ventilation..... If Peltier cooling was an efficient option, functionally and economically, it would have been a well travelled ancient route by now.....

U can Cascade or stack peltiers gradually increasing the size . It's a common practice.but it isn't necessarily efficient......
