ABSTRACT:
A heat transfer device is provided which has an improved energy efficiency, utilizes significantly less space and costs less than conventional condensers in refrigeration units. The heat transfer device comprises a plurality of coil units disposed in a serpentine configuration and which are juxtapositioned to decrease space requirements and increase heat transfer. The coil units are constructed by fist attaching a lateral fin to a tube. The tube is then bent to form a continuous helical structure and this helical structure is then bent to form a plurality of parallel interconnected individual units disposed in a serpentine configuration. Multiple rows of interconnected parallel units are arranged to interfit so that the condenser occupies a minimum amount of space.
