Peltier junctions. Used in all of those DC powered portable coolers (car cigarette lighter cord). It is essentially two sides of a thermopile (a thermocouple driven by a voltage instead of generating a voltage).
Hello, I have a similar cooler that heats but will not cool water. The same issue was seen with the fan not turning on but the element getting warm when turned on. I replaced the fan but it still does not turn on. Now I see and smell smoke when I turn on the cool water. Any thoughts?
Fan and circuit board works but not cooling the water. Does it make a difference which way the fan blows? Im thinking the peltier semiconductor may be at issue. It does not get warm.
I have the same problem. Fan work really well, hot water perfect but cold water not functioning well. Which electronic part that i need to change? Do u have any idea on this?
Try to change peltier module or thermo electric cooler ..or put grease paste .bcoz the supply power of fan same power supply it means same 12 volts fr peltier module...
My cousin just gave me his water cooler because it was not working. I haven't had time to take a closer look. So I assume there is no compressor, evaporator or condenser. I'll get at it soon. Thanks GFM!
You want to remove the heat, so usually the fan pulls the hot air away from the heat sink, however, I have seen many people prefer to push the fresh air onto the heatsink, and there is no noticeable difference in temperature, so I would say as long as there is plenty of fresh air allowed to flow - either way is good. If you are wondering about the set up in the video, the motor mounts will always be on the side that the air is going towards. So here, the motor mounts are outward, so the air is being pushed out towards us. :)
Yep had a portable cooler that had the fan die. These things are resultant devices. Put a new fan in mine and its 15 years old just fine. Known some people that have had them for years as truck drivers!
Very neat the way it cools. Thank you GFM for the knowledge.

GFM, Thanks for posting. Pretty cool little system

I've always wondered what kind of system is used in those coolers but I never pulled one out from the wall to inspect. Thanks for your video.
Thanks for this video GFM, I was not sure on that whole Peltier operation but this helped a lot. Thanks.
Where do you buy the fan? Is it easy to replace?

Fan direction is probably not the issue. If you are getting DC voltage to the semiconductor and no heat, the semiconductor is at fault.

@@grayfurnaceman I concur. A new one has been ordered. They are not expensive. Thank you for your video as it gave me clues to finding a solution.
My fan is running but the wayer wont cool. Any thoughts on this??
GM thanks for the follow up on this...
Again, great videos you produce !
What about if your fan is working and still no cold water
My fan works but the water doesn’t get cold!!!😔. Can you let me know what you think could be the issu!? The hot water works great. Please, thank you 🙏
The electronics have probably failed.

I have the same issue, any hint you can share?
The same issue
The fan is working fine but water not cold.

Does the fan need to blow in or pull out?
I think it blows out.

Have one, no cooling water, will look at fan , if need replace and works will let you know. Here.
Is it possible to use it for bigger application? For example Chiller? or water heater or Hybrid systems?
Guy Hakverdi Well, you could if you had more money than Bill Gates. The thermal efficiency is about 5% compared to 300 to 400% for refrigeration.

Hi,thnx 4 knowledge and skills I got from u,but my dispenser water not cooling? but I can get hot water only
If it doesn't cool you may have the same problem as this one. Check the fan.
GFM
My fan works though, what else could it be? The board and the wires are good.
So make sure the fan works ha?🤔
Where to get the cooling fan?
Its an OEM part.
