To dump the heat Use a thick towel and wet wrap the line keep it moist the hill billy way. They affix a 5 gallon bucket over it with ice water in it wit a drip on to towel.
Or mimic a lab glass coil the copper tight enough so it fits in pvc pipe not touching edges the copper leads out top and bottom epoxy in place the drill and insert two ribbed plastic tubeing nipple into the pvc pipe at 180 degrees from each other at opposite ens so one is facing sky ward and one is facing down earth ward put the pipe at a 45 degree angle to help the water inside the copper flow out. Attach a super low volume fish tank pump to the bottom nipple and slowly pump water into jacketing pvc once full have another line run off top so you can direct the over flow. Do not pup back into feed line for bottom as it will be warm and the bottom feed water should be cooler. The fish pumps come in 12 volt DC. That is how to cool the lines efficiently. Having a set water amount limits effectiveness as water heats ip. Even water in a stream on hot day will be cool enough to make the condensate happen very fast.
