[0002] Automobile air conditioning pipeline is an important component of air conditioning system, mainly used for transporting refrigerant (such as R134a or R1234yf), connecting compressor, condenser, evaporator and expansion valve and other key components. Its role is to form a closed circulation channel in the air conditioning system, so that the refrigerant can flow efficiently, thereby realizing refrigeration or heating function. Since the vehicle will face complex road conditions during driving, the air conditioning pipeline needs to have good sealing, pressure resistance and shock resistance to avoid refrigerant leakage or pipeline rupture, affecting the air conditioning performance.
