Heat exchanger for high purity fluid handling systems

1. Field of the Invention A novel heat exchanger includes a thermal reservoir and a tube, the tube having straight sections and corrugated bends, and being in thermal contact with the thermal reservoir. The thermal reservoir has a first plate and a second plate fixed to the first plate. The first plate has a channel formed therein with straight sections to receive the straight sections of the tube, and curved sections for receiving the corrugated sections of the tube. The second plate has a channel formed therein as well that is complementary to the channel of the first plate. The heat exchanger is heated by one or more cartridge heaters. In a particular embodiment, two thermal reservoirs are fixed to one another and the cartridge heaters are disposed in channels formed therebetween. Optionally the thermal reservoirs can be heated or cooled by thermoelectric chips, and can include one or more heat sinks.
