HEAT EXCHANGE TUBE FOR AIR CONDITIONER

摘要

PURPOSE: A heat exchange tube for an air conditioner is provided to secure a contact area of refrigerants by molding protrusions and heat exchanging efficiency by contacting refrigerants to a whole area inside the tube in refrigerants flowing and to supply optimum design conditions by solving defects of passage resistance and productivity caused by increasing the spiral angle and number of protrusions. CONSTITUTION: A heat exchange tube(10) for an evaporator of an air conditioner has protrusions(12) having the spiral angle of 5 or 10 degrees in an axial direction of the tube in the inside thereof(10a) and molds protrusions within three or ten.
