Heat exchange tubing
First Claim
1. A heat exchange device, comprising:
- an outer tube, having an inside diameter, and made of a flexible, formable material;
an inner tube, defining an inner conduit, the inner tube having an outside diameter which is less than the inside diameter of the outer tube, the inner tube extending coaxially through the outer tube thereby defining an outer conduit between the inner tube and outer tube, the inner tube floating within the outer tube; and
wherein the inner tube is made of metal for transmitting heat between the inner conduit and outer conduit, and whereby the inner tube and outer tube are together flexible and formable without kinking the inner tube, outer tube, and without blocking the inner conduit and outer conduit.

Abstract
A heat exchange device, for allowing the exchange of heat between a first medium and a second medium, using a coaxial double tube. The coaxial double tube includes an outer tube, and an inner tube which extends through the outer tube. The inner tube has an inner conduit for allowing a first medium to travel therethrough, and an outer conduit is formed between the inner tube and outer tube for allowing a second medium to travel therethrough while remaining physically isolated from the first medium. The outer tube is made of plastic, and the inner tube is made of metal, which allows heat to be transferred between the first medium and second medium and allows the tube to be selectively bent into a coil to minimize space for the heat exchange device.

5. A heat exchange device, comprising:
a coil, the coil formed with a double tube comprised of an outer tube, and an inner tube which extends through the outer tube, remaining substantially coaxial therewith throughout the coil, without physical connection between the outer tube and inner tube throughout said coil, the inner tube having an inner conduit for allowing a first medium to travel therethrough, an outer conduit is formed between the inner tube and outer tube for allowing a second medium to travel therethrough while remaining physically isolated from the first medium. - View Dependent Claims (6, 7, 8)
