Peltier Coolers

Post by cricket_belt »

Have been thinking about the use of these little gadgets (which can be readily googled if you're not familiar) in the HevORT.

Does anyone run a peltier cooled watercooling system? Does anyone know of any sources or examples of such a system?

Could these be used to facilitate easy ambient temperature manipulation with heatsinks and fans? To complete enclosure climate control...

You have to understand that these Peltier cooler will generated as much heat as they are generating cold. The electricity provided will simply sink heat from one side to the other. So if you leave a Peltier in a chamber without cooling its hotside, the overall cooling benefit will be null.

There is so many article on internet about this false good idea. Many of them about processor cooling.

Peltier cooler just move the heat energy to theire other side.. they need energy and need to expulse it also. It have a big energy cost as more you want cooling more you need energy.

Peltiers life expectancy is another issue. To get water temperatures lower a chiller is commonly used and a reliable option. Google „watercooling chiller“.

What elements of the enclosure environment are you trying to control?
I can't see any situation where you need the enclosure environment to be below normal lab temperatures (15-20C). In which case you can move any excess enclosure heat using a normal water cooling loop.
I had considered experimenting with thermoelectric cooling on a much smaller scale but haven't gotten around to experimenting yet.

Tech Ingredients on youtube have a few videos about using TEC to build a refrigerator, might be worth a watch.

Another issue oftentimes overlooked is that when you cool below ambient temps condensation inevitably happens - so you need a way to deal with it.
