Description
Изобретение относится к воздушному охлаждению в поверхностных теплообменниках.The invention relates to air cooling in surface heat exchangers.
Известен способ воздушного охлаждения В поверхностных теплообменниках путем ввода воды в охлаждающий воз- 5 Known is a method of cooling air in the surface heat exchangers by inserting the cooling water in WHO-5
ДУХ И ·SPIRIT AND
Недостатком известного способа является недостаточно высокая степень теплосъема из-за того, что не обеспечи- ,0 вается необходимый контакт между охлаждающим воздухом и водой.A disadvantage of the known method is not sufficiently high degree of heat removal due to the fact that it is not ensured, 0 INDICATES necessary contact between the cooling air and water.
Цель изобретения - повышение теп— лосъема.The purpose of the invention is to increase heat loss.
Указанная цель достигается тем, что 15 ввод воды осуществляют импульсно с частотой 0,005-0,1 Гц при отношении длительности импульса к длительности паузы 0,01-1,0.This goal is achieved by the fact that 15 water input is carried out in a pulse with a frequency of 0.005-0.1 Hz with a ratio of pulse duration to pause duration of 0.01-1.0.
Способ осуществляется следующим 20 образом.The method is carried out as follows 20.
При работе теплообменника осуществляется импульсный ввод воды в охлаждающий воздух. Частота импульсной по— дачи воды и длительность выбирается в зависимости от температурного режима работы теплообменника, чтобы к моменту поступления свежей порции воды предыдущая испарилась для обеспечения свободного растекания воды по поверхности. Оптимальным диапазоном частоты является 0,005-0,1 Гц, а оптимальное отношение длительности импульса к длительности паузы составляет 0,01-1,0.During operation of the heat exchanger, pulsed water is introduced into the cooling air. The frequency of the pulsed water supply and the duration are selected depending on the temperature regime of the heat exchanger, so that by the time a fresh portion of water arrives, the previous one evaporates to ensure free flow of water on the surface. The optimal frequency range is 0.005-0.1 Hz, and the optimal ratio of pulse duration to pause duration is 0.01-1.0.
При вводе Borifci в охлаждающий воздух, вода растекается по теплообменной поверхности и движется по ней в режиме пленочного течения, обеспечивающем увеличение теплосъема. Кроме того, уменьшается гидравлическое сопротивление потоку охлаждающего воздуха.When Borifci enters the cooling air, water spreads over the heat exchange surface and moves along it in the film flow mode, providing an increase in heat removal. In addition, the hydraulic resistance to the flow of cooling air is reduced.
