Description
Изобретение относится к устройствам для изменения теплопередачи.The invention relates to devices for changing heat transfer.
Целью изобретения является интенсификация теплообмена и улучше ние очистки поверхности при ее вертикальном расположении.The aim of the invention is the intensification of heat transfer and the improvement of surface cleaning in its vertical arrangement.
На фиг.1 изображено предлагаемое устройство для интенсификации теплообмена; на фиг.2 - схема расположения упругих полосок.Figure 1 shows the proposed device for the intensification of heat transfer; figure 2 - arrangement of elastic strips.
Устройство содержит систему упругих полосок 1 дугообразной формы, шарнирно закрепленных на стержнях 2, которые в шахматном порядке прикреплены перпендикулярно к вертикальной поверхности теплообмена 3. Стержни 2 расположены с продольным и поперечным шагами, превышающими продольный размер полоски 1. Полоски 1 соседних рядов при этом выполнены с противоположным изгибом.The device contains a system of elastic strips 1 of an arcuate shape, pivotally mounted on rods 2, which are staggered perpendicular to the vertical surface of the heat transfer 3. The rods 2 are arranged with longitudinal and transverse steps exceeding the longitudinal size of the strip 1. The strips 1 of adjacent rows are made with opposite bend.
Устройство работает следующим образом.The device operates as follows.
В первоначальном положении полоски 1 свободно свисают под действием силы тяжести. При течении теплоносителя вдоль поверхности 3 полоски 1 под давлением жидкости поднимаются и благодаря дугообразной форме и их упругости, а также действию силы тяжести, они постоянно колеблются, турбулизируя при этом пограничный слой теплоносителя и интенсифи-In the initial position, the strips 1 hang freely under the action of gravity. When the coolant flows along surface 3, the strips 1 under pressure of the liquid rise and due to the arched shape and their elasticity, as well as the action of gravity, they constantly oscillate, while turbulizing the boundary layer of the coolant and intensifies
