_SRZ Fin heat sink fins _SRZ5 × 5D

_SRZ Fin heat sink fins _SRZ5 × 5D heating and cooling is provided by Zhangdian Xinyuan Blower. _SRZ Fin heat sink fins _SRZ5 × 5D is Zhangdian Xinyuan heating and Blower (www.3881321.com/) 2013 been newly launched upgraded stainless steel wound finned radiator to expand the area of ??contact with the gas tube, eliminate the tube inside and outside heat transfer coefficient differences; appearance, compact structure, efficient heat transfer can be achieved in a smaller space. Stainless steel tube gas radiator is typically used for corrosion, or for heating gases cleanliness requirements of the occasion, the material used is 301; 304; 321; 316. The pressure in the tube of stainless steel heater temperature is relatively high, the floating head heat sink may be used, or S; U-type curved tube to solve the problem of expansion and contraction stress. Surface treatment of stainless steel radiator; before welding the weld should be painted lime around SRZ5 × 5D fins reduce spatter. Polished surface to minimize and avoid damage to the dense oxide film. Welding can be passivated SRL5 × 5/2 fins until exposing the white metallic luster, the processing of large surface to be polished, shot peening and other programs. The design of the radiator is calculated according to the following steps: 1, primary radiator models. Generally assumed from the effective cross-sectional area through the heat sink air mass flow rate to carry out. Assuming the mass flow rate of air can be drawn from the effective cross-sectional area of ??the heat sink needs. 2, the heat transfer coefficient calculated radiator. Once you have the radiator models and air mass flow rate, calculate the heat transfer coefficient. 3, the heating radiator area and the number of computing needs. Heating area is calculated to determine the actual quantity of heat sink area of ??each radiator. 4, check the safety factor of the radiator. Safety factor safety factor generally take the heat transfer area of ??1.1-1.2
