Description
Изобретение относится к теплотехнике, а именно к трубчато-пластинчатым теплообменникам, и может быть использовано в энергетическом и химическом машиностроении.The invention relates to heat engineering, namely to tubular-plate heat exchangers, and can be used in energy and chemical engineering.
Цель изобретения - интенсификация теплообмена.The purpose of the invention is the intensification of heat transfer.
На чертеже изображен пакет трубчато-пластинчатого теплообменника, об«ций вид.The drawing shows a package of tubular-plate heat exchanger, view form.
Пакет трубчато-пластинчатого теплообменника содержит пучок из рядов круглых труб 1, расположенных в шахматном порядке на пересекающихся диагоналях. На трубах 1 укреплены плоские пластины 2,. между которыми на ‘ трубах дополнительно размещены гофрированные пластины 3 с образованием конфузорно-диффузорных каналов 4. 2о Расстояние мёиадуплоской пластиной 2 й средней линией соседней гофрированной пластины 3 (0,285-0,315)d, где d -внешний диаметр трубы.The tubular-plate heat exchanger package contains a bundle of rows of round pipes 1 arranged staggered on intersecting diagonals. On the pipes 1 reinforced flat plates 2 ,. between which corrugated plates 3 are additionally placed on the pipes with the formation of confuser-diffuser channels 4. 2 о Distance between the flat corrugated plate and the 2nd middle line of the adjacent corrugated plate 3 (0.285-0.315) d, where d is the outer diameter of the pipe.
Пакет теплообменника работает еле- 25 дующим образом.The heat exchanger package works in the following way.
По трубам 1 пропускают одну из теплообменивающихся сред (хладоноситель). Другая среда, в частности воздух, проходит между плоскими 2 и гоф- 3θ рироваиными 3 пластинами в межтрубном пространстве, обмениваясь теплом с первой средой.The pipes 1 pass one of the heat-exchanging media (coolant). Another medium, in particular air, passes between the flat 2 and corrugated 3 θ 3roir plates 3 in the annulus, exchanging heat with the first medium.
При течении теплоносителя в меж-, Трубном пространстве по конфузорнодиффузорным каналам, образованным 35 : ? ' /' . t соседними плоскими и гофрированными пластинами с расстоянием между плоской пластиной и средней линией соседней * гофрированной пластины, составляющим (0,285-0,315)d, где d - внешний диаметр трубы, возникает оптимальный продольный знакопеременный градиент давления без образования стабильных вихревых структур в ядре потока рабочей среды. Это обеспечивает гарантированное снижение выработки мелкомасштабных турбулентных вихрей и приводит к перераспределению переноса * количества движения и теплоты, что интенсифицирует теплообмен при незначительном возрастании гидравлического сопротивленияWhen the coolant flows in the inter-, pipe space along the confuser-diffuser channels formed by 35 :? '/'. t adjacent flat and corrugated plates with a distance between the flat plate and the middle line of the adjacent * corrugated plate constituting (0.285-0.315) d, where d is the outer diameter of the pipe, an optimal longitudinal alternating pressure gradient occurs without the formation of stable vortex structures in the core of the working fluid stream . This provides a guaranteed decrease in the production of small-scale turbulent vortices and leads to a redistribution of transport * of the momentum and heat, which intensifies heat transfer with a slight increase in hydraulic resistance
