Abstract:
A miniature recycle-type heat exchanger production method, said method comprising the steps of:annealing copper and aluminum billet (ingot) material,conveying said material to a vibrator for placement in an ordered arrangement, andthen conveying and fixing said material onto molds in a pressure forming press for extrusion tasks required to produce round, square, rectangular, or irregularly contoured heat exchanger bodies;in a final stage, after shaping and determination of a fluid input direction, placing said bodies in a vacuum sputtering machine for application of a rough textured heat conductive microparticulate deposition process over all surface areas that also increases surface strength;wherein a miniature recycle-type heat exchanger is produced that is of very compact dimensions that is lightweight and has a large heat exchange capacity and a high heat transfer rate.
