immersion chiller am I wasting my money?

Can some one enlighten my ignorance please.
What is a "goat exchanger", I bet it's bloody obvious.

sorry silly joke, but straight pipe counterflow chillers (or multiple liebig condensors) started getting called goats cos the cheap long cleaning brushes for scrubbing out long tube lengths came from a goat husbandry web site for cleaning out milking tubes;)

my SS (14 legged) goat...

Thanks Fil, I've seen that before on the other Forum, never knew it was called a "goat"
