Cooling For Peltier/TEC

If I were to put 4 Peltiers on a reservoir inside a HAF Stacker, would it be enough to cool these with 6, 120mm fans or is liquid cooling required?
Would there be much of a difference between air cooling vs liquid cooling?

  1. you will need to put a cpu heatsink/fancombo to cool the hotside of the plate
  2. I don't see the reservoir as having enough surface area .... and if you are not using liquid cooling what is inside the reservoir ?
  3. i think he was talking about cooling the hot side of the thermoelectric cooler

    yes, i mean to cool the hot side of the TECs only

    Is there a reason that I cant use this reservoir and place two of these TEC Peltiers on each side of it? The reservoir's side are 90mm x 42mm, and the TEC Peltiers are a mere 40mm x 40mm, which should give just enough room, correct?

    dont do that the plastic reservoir will act as a vary good insulator and it wont cool the water. you need to ether use a metal version of the reservoir or you could cut rectangle holes put heatsinks in the holes and attach the tec to the heatsink.
  7. if i used a metal reservoir, how might I attach the Peltiers to the side of it? just thermal paste, or what?

  9. that could work or add a bit of epoxy or silicon around the sides in addition to the thermal paste under it. make sure you have a heatsink on the hot side though or it will not work good.
  10. watch out for condensation though.

    I'm a little confused...I've never even heard of these plate heat exchangers. How does it work? And don't I just need two holes, not four (one intake, one exhaust)? Looks intriguing

    Can you recommend a good one for 1/2" ID tubing, instead of 3/8"?

    yes thank you, I've already planned to handle this

  13. wish i could help i know nothing about those p[late heat extangers
  14. Heat exhangers are oft used in engine cooling where air cooling of radiators provides insufficient thermal exchange.... the engine coolant is in a closed loop that uses water in another loop to cool it. Think of putting your radiator in a reservoir.

    The way they are normally used is you have your closed water loop running as any typical water loop for a custom water cooled PC ... that covers one in and out. In it's simplest form, you run a line from your home's water supply to the 2nd inlet and then the outlet can go to an outdoor pond or whatever. That gives you an "ambient" of 55F instead of the typical 72F

    Most used a closed loop for the 2nd loop .... can even be incorporated into a home geothermal heating / cooling loop.
