Yong Heng Cooling what has worked and what about a larger capacity water pump?

Back in the day some of the guys were blowing up their 409 Chevy engines because the oil pump was so efficient that it pumped all the oil up into the engine faster then it it could return to the oil sump.

Likewise some of the hotrodders that designed their own cooling systems were pumping the water thru the radiator too fast for it to cool properly.

Like heavy-impact said "good enough is good enough.

Nice Setup. I had heat problems until I decided to use the entire sink instead of a cooler. For long fills I let the sink drain slowly while refilling with cold water. Never had a heat problem after that. Now I just keep blowing the seal at around 220bar. Scares the heck out of me. I decided to use two pressure disks so now I'm just hoping there isn't some other problem that I'm overlooking. Anyone?

In a closed loop system like we're using no matter how fast you pump each water molecule spends the same amount of time inside the water jacket of the heat source absorbing heat. Assuming the water temperature remains well below phase change and has 100% contact with the heat source and heat sink you would have to increase the water contacting surface area of the heat source or increase the efficiency of the heat sink to increase cooling capacity.

In a closed loop like we're using, pumping losses are determined by restrictions rather than head pressure so height difference of the loop won't matter. Once the water is flowing the fall siphon equals the head pressure. 

These compressors don't have a large water jacket surrounding the cylinder, they have a hole drilled for water to pass with a relatively small contact surface for heat exchange.

In this simplified explanation I may not have used the proper terms because I'm not an expert but I'm sure you get the gist.

If you're going to watch it the whole time you'd be better off installing a 6000psi gauge in that port to see what's happening.

Why not just hook up the tube to your sinks water tap? Let the water pressure push the water through and then just let it run into a drain. Constant flow of cold water and no worry about icing down the water.
