Abstract
A heat exchanger is provided with a first conduit which utilizes a reverse spiral concept and a second fluid conduit which directs a fluid in thermal communication with the first conduit. One of the fluid conduits of the heat exchanger is formed with a generally S-shaped portion which creates a reverse spiral configuration and which permits a heat exchanger to take advantage of the spiral conduit design while avoiding the typical disadvantages that are generally experienced with spiral conduit configurations. The reverse spiral concept permits both ends of the reverse spiral tube to be easily accessible from a radially outward direction relative to the spiral configuration.
