The inner-grooved copper tube has the characteristics of uniform and dense organization, high dimensional accuracy, complete tooth profile specification, low internal cavity residue, the internal surface area has been increased by 65~100% compared with the same type of smooth copper tube, the heat transfer efficiency is 1.8~2.0 times than the same type of smooth copper tube. It is widely used in air conditioning and refrigeration industry, adapt to the air conditioner developing trend with high efficiency, energy saving, environmental protection and health.
