Abstract
The present invention comprises a cooling coil configuration that permits an extended length of coil in a smaller total volume of water bath utilized, than is seen in such coils in the prior art. The coil of the present invention is made from a continuous length of stainless steel tubing that is bent in a manner to provide for the desired configuration. In one embodiment, the full coil is made up of four sub-coils generated by bending the tube through a plurality of consecutive 180 degree or semi-circular arcs having straight tubular portions intervening there between. In order of bending, there is a first large arc, a second medium sized bend of smaller circular diameter than the large bend, three consecutive small bends all of the same size and of a further smaller diameter than the medium bend, a further medium sized loop the same dimension as the previous medium one, and ending with a large loop, again of the same dimension as the first large loop. The loops are collapsible partially within each other in a manner that conserves the total volume thereof.
