More Information
Summary:The invention discloses a capillary tube. The capillary tube comprises a tube body; the tube body is provided with a circular-arc-shaped groove; the front end and the rear end of the tube body are of a closed structure respectively; a tin layer is arranged outside the tube body. According to the capillary tube, the tin layer is arranged outside the tube body in a plating mode and accordingly the leakage of the refrigerant pressure is effectively avoided, the product scrap rate is low, the product quality is good, and accordingly the development space of the capillary tube is broad.
