Title:
HEAT EXCHANGER MADE FROM BENDABLE PLASTIC TUBING
Document Type and Number:
WIPO Patent Application WO2002029347
Kind Code:
A3
Abstract:
A plastic tube heat exchanger suitable for refrigerant use is provided by wrapping a layer of tubes (10) around a curved surface (12), on a base (11) which is generally perpendicular to the surface (12). Several to many tubes (10) can be in each layer. Then, further layers can be wrapped continuously by overlaying the first layer. Heat exchangers, including refrigerant apparatus, condensers and evaporators, can be made in this configuration. Processes and articles of manufacture are parts of the invention.
