The purpose of this project is to create a device that can pump 1kW of thermal energy between two separate loops of water.
The primary loop of water is the hot side and acts like any water cooling system. It has a pump, reservoir and heat exchanger to the air of about a 100W. However, there is also a front panel bulkhead port to allow the water loop to travel to larger radiators or (and here's the fun part) just have a continuous source of cold water from the tap flow through.
The secondary loop of water is thermally connected to the primary loop of water via two sandwiched "cold-plates" with 12 40mm Peltier heat pumps in the middle (a 1 kW heat-pump). Combined with the temperature controller, this allows me to set the desired temperature of the secondary water loop. The targeted range so far is 0-30C.
Once everything is up and running I should be able to practically dissipate over 500W with inlet coolant temperatures to the thermal source at 1C.
Both loops have a temperature/flow meter (with alarms) and there is another cut-off temperature controller watching the maximum temperature on the primary water-loop (pump is rated for 65C) that can cut the Peltiers/alarm).
I just wanted to do this for fun.
It also cost a LOT, so parts will be purchased very slowly and assembly will lag behind. Also, the parts list is mostly accurate (it's hard to be sure when you don't have most of them).
