The radiator water pipe is responsible for transporting coolant and supporting heat dissipation circulation and temperature control. Materials resistant to -40 ℃~120 ℃ and coolant corrosion shall be selected. The pressure shall be 0.3-1.5MPa and sealed to prevent leakage. The inner wall shall be smooth to reduce resistance, with strong interface adaptation, vibration resistance and aging resistance to ensure the stability of the equipment.The core of the radiator water pipe transfers coolant to assist in heat dissipation. Made of high and low temperature resistant, corrosion-resistant materials, capable of withstanding pressures of 0.4-1.6MPa without leakage, with smooth inner walls and reduced resistance, wide interface compatibility, vibration resistance and durability, suitable for the heat dissipation needs of automobiles and industrial equipment.
