* By using a distributor for liquid separation, the refrigerant distribution in the tube side is ensured to be uniform, improving the design of the tube side and maximizing the use of heat exchange area, resulting in good heat transfer performance

*In terms of process, the expansion joint has been changed to welding, which has high compressive strength and greatly improves the reliability of the product.  The tube sheet and tube box are eliminated, and the distributor, collector and heat exchange tube are welded together, so that the multiple systems are completely independent and there is no risk of refrigerant leakage;

*Resistant to dirt, blockage, and freezing, with short tail overhang and good vibration resistance, overcoming the problem of vibration and fracture of heat exchange tubes
