Description
(54) УСТРОЙСТВО ДЛЯ ИНТЕНСИФИКАЦИИ ТЕПЛООБМЕНА(54) DEVICE FOR INTENSIFICATION OF HEAT EXCHANGE
ти теплообмена, так как колебани полосок преа тствуют загр знению,,these heat exchanges, since the vibrations of the strips prevent contamination,
На чертеже изображено предлагаемое устройство, общий вид.The drawing shows the proposed device, a General view.
Полоски 1, выполненные иэ гибко-неупру- гого материала, креп тс , например, клеем к поверхности 2 теплообмена.The strips 1, made of flexible and inelastic material, are attached, for example, by glue to the heat exchange surface 2.
Устройство работает следующим образом.The device works as follows.
В первоначальном положении полоски 1 свободно провисают под действием силыIn the initial position, the strips 1 loosely sag under the action of force.
т мсести и располагаютс под углом к поверхности 2 теплообмена. При движении жидкости на полоски действует сила гидродинамического давлени , котора стремитс выпр мить полоски и прижимает их к йоверхнооти теплообмена. В результате уменьшени угла атаки сила гидродинамического давлени уменьшаетс . После этого сила т жести, направленна нормально к поверхности теплообмена возвращает полоски в первоначалЕ ное положение. Затем процесс повтор етс . Таким образом, полоски совершают колебательное движение и в направлении, перпендикул рном поверхности теплообмена.tons of space and are located at an angle to the heat exchange surface 2. As the fluid moves on the strips, the force of hydrodynamic pressure acts, which tends to straighten the strips and presses them to the heat exchange surface. As a result of decreasing the angle of attack, the force of the hydrodynamic pressure decreases. After this, the force of gravity, directed normally to the heat exchange surface, returns the strips to their original position. The process then repeats. Thus, the strips make an oscillatory motion in the direction perpendicular to the heat exchange surface.
Разрушение пограничного сло движущейс жидкости за счет колебаний полосок вызывает рост интенсивности теплоотдачи на 60-160% при практически неизменном гидравлическом сопротивлении.The destruction of the boundary layer of a moving fluid due to oscillations of the strips causes an increase in the heat transfer intensity by 60–160% with practically unchanged hydraulic resistance.
Формула изобретени Invention Formula
Устройство дл интенсификашш теплооб-мена между потоком вещества и поверхностью , содержащее систему полосок, отличающеес тем, что, с целью повышени теплоотдачи и очистки поверхности, полоски выполнены из гибкого неупругого материала и прикреплены одним концом к поверхности.A device for intensifying heat exchange between the flow of a substance and the surface, containing a strip system, characterized in that, in order to increase heat transfer and surface cleaning, the stripes are made of flexible inelastic material and attached at one end to the surface.
