Inner Grooved

Inner Grooved copper tube is one of the QAEM Products. To improve the heat transfer characteristics of tube, the inner surface of the tube is provided with spirally running grooves. Increased internal surface area, turbulent flow of refrigerant and uniform distribution of refrigerant around the periphery of tube cause increment of efficiency. Heat transfer coefficient of these tubes is about 1.8-2 time of the same specification of plain tube. It is widely applied in Air Conditioning and Refrigeration Industries, which are in conformance with the developing tendency of the air conditioner to high efficiency, energy saving, environment-friendly and healthy.
