Inner Grooved Copper Tube

Tubesolutions’ inner grooved copper tube’s compact structure, the highly precise dimension, the normative and integrity groove shape, the low interior surface residuum, etc., the inside surface area increases 65～100% than that of the same specification of plain copper tube, the heat transfer coefficient is about 1.8～2.0 times of that of the same specification of the plain tube, inner grooved copper tube is widely applied to the Air Conditioner, the Assembly Type Air Conditioning Unit, the Residential Central Air Conditioning, Show Case Refrigerator which is in conformance with the developing tendency of the Air Conditioner and Refrigerator to the high efficiency, the energy saving.

Inner Grooved copper tube is to improve the heat transfer characteristics of copper tubes and heat exchangers, the inner surface of the tube is provided with spirally running grooves. The heat transfer coefficient of these tubes is about 2～3 times higher than that of the same specification of a plain tube. Increased internal surface area, turbulent flow of refrigerant and uniform distribution of refrigerant around the periphery of the tube cause increment of efficiency. By using the I.G tubes in fin block heat exchangers, the efficiency of the heat exchanger can be increased up to 30% depending on the application. In general, advantages that can be gained from usage of I.G tubes are: smaller unit size with unchanged efficiency, saving in material cost, space savings, smaller fan, and reduced noise level, smaller compressors, and energy saving.
