Put the whole lot in the freezer as I can't cut holes until I find the mandrel for my hole saws.
At least I can test if there is enough heat transfer to the coolant. The freezer copes with just the electrical heat load with ease. Total electrical heat load is 7A x 14V = 98W. The freezer is rated at 190W so it should pump 400W+.
It looks like I need a radiator or long length of copper pipe inside the freezer to cool the coolant as it slowly heats up even though the freezer is at -18C. The copper based cooking pot is not transfering enough heat to the freezer.
Heat getting in to the coolant depends how well the Tygon tubes are insulated.
