Will a peltier based coolant chiller run the risk of freezing within the cooling block?
Post Body
I'm creating a peltier based chiller by placing a TEC-12712 (120W heat removal capacity) on top of a CPU liquid cooling water block. Assume that:
- I have a fan and heat sink that can effectively remove most of the head that the peltier is generating
- The system is moving 1 gallon / minute, so essentially 1 gram of water per second through a copper block capable of holding 25 grams (if my calculations are correct)
- Incoming water temperature could range from 15C - 35C, and is run through two of these chilling blocks
Will enough heat energy be transferred through the copper block / peltier to run the risk of water freezing inside the block and slowing or inhibiting flow? Or is that just not possible?
