What factors can affect the operating temperature of finned tube radiator? Finned tubes are divided into various forms and raw materials, which are commonly used for industrial heating and cooling purposes. The application temperature regulation of fin tube radiator will affect the function and service life of the radiator. Fin tube radiator is an indispensable heating equipment in today's family life, many families choose to use this radiator to get better life experience. High quality fin radiator can shorten the time of thermal energy interaction and reduce the energy consumption in actual use, so the use of fin radiator has become an inevitable development trend.
影响翅片散热器效果的因素都有哪些?
What are the factors that affect the effect of fin radiator?
1、翅片管散热器受到外界环境的温度影响。根据对流换热理论和热传导理论可以得知翅片散热器使用的效果与外界环境的温度关系紧密,对于同一个散热体而言外界温度越高翅片散热器的热交换能力越弱,因此在室内温度较低的环境之下安装使用翅片散热器,才能够更好的感受该散热器卓绝的散热效果。
1. The fin tube is affected by the outside temperature of the radiator. According to the convection heat transfer theory and heat conduction theory, we can know that the effect of fin radiator is closely related to the temperature of the external environment. For the same radiator, the higher the external temperature is, the weaker the heat exchange capacity of the fin radiator is. Therefore, the excellent cooling effect of the radiator can be better felt by installing and using the fin radiator in the lower indoor temperature environment.
2、受到设备自身导热性能影响。在我国市面上所销售的翅片散热器类型众多,翅片数量的对散热实际性能都有着较大的影响,因此消费者选购抗热耐磨的翅片散热器便能够享受更加导热效果。翅片散热器焊缝更加光滑平整,散热的面积更大,因此消费者只有选择出这种翅片散热器才能够保证散热效果。
2. It is affected by the thermal conductivity of the equipment itself. There are many types of fin radiators on the market in China. The number of fins has a great impact on the actual performance of heat dissipation. Therefore, consumers can enjoy more heat conduction effect by choosing heat resistant and wear-resistant fin radiators. Fin radiator weld is smoother and smoother, and the heat dissipation area is larger. Therefore, consumers only choose this fin radiator to ensure the heat dissipation effect.
3、受到空间大小的影响。翅片散热器的热能在空气之中传播与空间大小有着紧密的作用,在较大空间之内吃片,散热器的实际单热性能会受到一定的影响,因此消费者在安装购买翅片散热器之前,应当了解该设备所能承受的散热空间。
3. Affected by the size of the space. The heat energy of fin radiator spreads in the air and has a close effect on the size of the space. If you eat a piece in a larger space, the actual single heat performance of the radiator will be affected to a certain extent. Therefore, consumers should know the heat dissipation space that the equipment can bear before installing and purchasing the fin radiator.
4.和翅片原料r的熔点有联系,翅片原料包含铝、碳钢、铝的熔点是660℃。所以含铝的翅片管不适用于高温烟气的换热体系中。考虑到高温烟气具有硫的成分,翅片管散热器应用ND钢,翅片类型选用高频螺旋翅片管。
4. It is related to the melting point of the fin material R. the melting point of the fin material including aluminum, carbon steel and aluminum is 660 ℃. Therefore, aluminum containing finned tube is not suitable for high temperature flue gas heat exchange system. Considering the sulfur composition of high temperature flue gas, ND steel is used for fin tube radiator, and high frequency spiral finned tube is selected as fin type.
5.和制作的工艺有关。一般在钢铝复合翅片管到达210℃,而普通绕钢片的翅片管到达150℃左右后,其接触热阻曲线呈显助的上升趋势。
5. Related to the manufacturing process. Generally, when the steel aluminum composite finned tube reaches 210 ℃, and the common finned tube with steel sheet reaches about 150 ℃, the contact thermal resistance curve shows a significant upward trend.
6.一般状况下,和基管的壁厚联系影响不大。普通无缝钢管正常壁厚状况,其耐压才能比较高,钢管壁厚必定的状况下,随钢管直径的增加,耐压才能下降。
6. In general, it has little influence on the wall thickness of the base pipe. Under the condition of normal wall thickness, the pressure resistance of ordinary seamless steel pipe can be relatively high. When the wall thickness of steel pipe is fixed, the pressure resistance can be reduced with the increase of steel pipe diameter.
7.和管板,管箱的强度有关。管板,管箱的壁厚越厚,翅片管散热器的承压才能越高。
7. It is related to the strength of tube sheet and tube box. The thicker the wall thickness of tube sheet and tube box is, the higher the pressure of fin tube radiator can be.
8.和焊接是否有缺陷有关。焊接时产生的缺陷气孔、夹渣、裂纹等影响翅片管散热器的承压才能,而压力与温度一般都呈正比联系式。
8. It is related to whether there are defects in welding. Defects such as blowholes, slag inclusions and cracks produced during welding affect the pressure bearing ability of fin tube radiator, and the pressure and temperature are generally in direct proportion.
