Abstract
A heat exchanger having at least one inner conduit comprising of a second tubular member coaxially disposed within a first tubular member, wherein the second tubular member outer surface is in contact with the first tubular member inner surface. Each of the first and second tubular members is composed of a material with an approximately 0.015 inch maximum wall thickness.
Claims8
A method for constructing a heat exchanger from a first refrigeration tube, and a second refrigeration tube, the method comprising:
- (a) inserting the first refrigeration tube, including a first inner surface, a first outer surface, and having a first diameter into a second refrigeration tube, including a second inner surface including continuous enhancements formed longitudinally therein, a second outer surface, and having a second diameter;
- and
- (b) expanding the first refrigeration tube within the second refrigeration tube to bring the first outer surface into contact with the enhancements of the second inner surface, thereby forming an inner conduit.
