Talking Re: Hot water testing of the parallel and stock IC.
Dinasrt. Hello; Well I gotta tell you that I am concerned by my finding and have even entertained putting back my test setup to do another test. I really have not gotten over the disruption it did to the house last time yet.

This test would be to take a stock IC and do the same test, the variable function would be that I would run like 3 GPM thru the IC and hold that constant, while varying the static water pressure. My thinking is that the low pressure was causing cavitation within the stock IC making voids that reduced the cooling effect. If this is so as the water pressure increased above some critical pressure, I would see heat rejection increase up to that point. To refresh your memory, as the water flow in the stock IC increased - sucking water out of it harder, the heat rejection fell ---not increased. The lower restriction parallel path IC did not exhibit this anomoly ( sp.)

My super cooler design had a pressure cap on it and I will have to pop the grill to read its value, though it might not build much pressure due to the very large size H/E. Like you I am planning on adding a water pressure gauge to my separate IC water circuit just to monitor the pressure. This is exciting to me as I may have found a deficiency in the separated IC water circuit, leading to less than optimum IC operation due to low static water pressure - something that I at first considered to be a good thing.

Billy22bob, you can see what I am talking about, the water flow increased and I fear so much that at the lower pressure of a separated IC water circuit, that the turbulent flow exceeded the waters ability to be a fluid. It was vaporizing due to its heat and low pressure from restriction in the core and boiling - cavitating which reduced the wetted core surface and actually decreased the heat that was rejected from the IC. Valuable infromation, but totally unexpected by me...........

If we get some Va snows Ill be trapped inside and forced to rerun this test..........Enjoy, WDY.........Durned hard to type with my siamese on the keyboard and my wrists, hee hee
