After boiling your wort, it is essential to bring it down to yeast pitching temperature in as little time as possible, that is why you need a wort chiller. The reason for this is to minimize the amount of time your wort is exposed to possible contaminants and reduce the chances of having off flavours in your homebrew due to dimethyl sulfide. Another reason for cooling your wort as quickly as you can is to avoid what is called chill haze, which is caused by the proteins being allowed to re-dissolve due to the fact they were not 'shocked' out of the wort.
So how does an immersion wort chiller work? Cold water goes into one end of the chiller coil, and as it circulates through the coil, it cools the wort. The warm water exits through the other end of the coil and may be used later for cleaning. Both stainless steel and copper immersion wort chillers work well for quickly reducing the temperature of your wort, and deciding which one works best is a personal preference. Stainless steel chillers will last you a very long time, look good and are easier to clean. Copper chillers may work slightly faster, the finish tends to oxidize, they are more pliable (so if not handled properly they could kink) and the cost may fluctuate depending on the market.
Are you interested in how a plate chiller works? The cold water flows through the plates in one direction while the wort travels in the opposite direction and then into your fermenter.
