1. SRZ Heatsink Overview
1.SRZ radiator is used as an air heater for heating air in hot air devices. It is mainly used for air heating of hot air heating, air conditioning systems and drying devices. It is the main equipment in hot air devices. Suitable for both steam systems and hot water systems. It is composed of carbon steel frame and carbon steel heat dissipation pipe (carbon steel heat dissipation pipe). The steel heat dissipation pipe is fixed by frame, with compact structure, good air tightness and convenient installation. SRZ steel radiator is widely used in current industrial and mining enterprises, heating and ventilation systems of large buildings and air heating systems of drying devices.
2. The SRZ radiator is composed of three rows of cross-arranged spiral finned tubes in the air flow direction, which are cross-arranged. The processing technology is to wind the cold-rolled steel strip on the seamless steel pipe by mechanical winding method. SRZ steel radiator plates have three types of spacing: 5mm-large "D", 6mm-medium "Z" and 8mm-small "X", with a total of 38 specifications.
3.SRZ type radiator working medium: steam working pressure is 0.3-8kg/cm2, hot water temperature can be around 130-70 ℃.
4.SRZ radiator model description: SRZ ① × ② ③-
①-Indicates that the long dimension of the normal section of the Poetry radiator is decimeter.
②-Showing the poetic radiator Tongrui normal section width dimension decimeter
③-Indicates the heat dissipation capacity of the steel radiator (large D, medium Z, small X)
