板式热交换器板片


    1878年德国人发明板式换热器,并取得专利。到1886年,由法国M.Malvazin初次规划出沟道板板式换热器,并在葡萄酒出产中用于灭菌。R.Seligman在1923年成功地规划了能够成批出产的板式换热器,开始时是运用许多铸造青铜板片组合在一起,很像板框式压滤机。1930年今后,才有不锈钢或铜薄板限制的波纹板片板式换热器,板片附近用垫片密封,从此板式换热器的板片,由沟道板的方式跨入了现代用薄板限制的波纹板方式,为板式换热器的开展奠定了根底。

    板式换热器当前已大量地使用于工业中,是一种高效、紧凑的热交换设备。它的开展已有一百多年的前史。经过广泛的使用与实习,大家加深了对板式换热器优越性的知道,跟着使用领域的扩大和制作技能的前进,使板式换热器的开展加速,当前已成为很重要的换热设备。

    与此同时,流体力学与传热学的开展对板式换热器的开展做出了重要的奉献,也是板式换热器规划开发最重要的技能理论依据。19世纪末到20世纪初,雷诺用试验证明了层流和紊流的客观存在,提出了雷诺数——为活动阻力和丢失奠定了根底。此外,在流体、传热方面有杰出奉献的专家还有瑞利、普朗特、钱学森、周培源等。

 

1878 germans send clear plate heat exchanger, and patented.By 1886, by the French M.M alvazin first planning out of the groove but plate heat exchanger, and used for sterilization in the wine produced.R.S eligman in 1923 succeeded in planning can produce a batch of plate heat exchanger, is used at the beginning of many casting bronze sheet piece together, like a plate and frame filter press.In 1930, in the future, just have stainless steel or copper sheet of corrugated plate heat exchanger, plate with gasket seal, near of plate heat exchanger plate, into the modern drawing by ditch but they limit way of corrugated plate, laid the foundation for plate heat exchanger.Plate heat exchanger current has been extensively used in industry, is a kind of high efficient and compact heat exchange equipment.It has one hundred years of history before.After extensive use and practice, deepen the advantages of plate heat exchanger of known, with the enlargement in the field and production skills to go forward, make the development of plate heat exchanger acceleration, the current has become a very important heat exchange equipment.At the same time, the development of fluid mechanics and heat transfer in plate heat exchanger development has made great dedication, and planning development of plate heat exchanger is the most important skills.The end of the 19th century to the beginning of the 20th century, with Renault test proved that the objective existence of laminar flow and turbulent flow, put forward the Reynolds number, resistance loss and laid the foundation for activities.In addition, in terms of fluid flow, heat transfer to expert with outstanding dedication and Rayleigh, prandtl, qian xuesen, Zhou Peiyuan, etc.
