Claims (2)

Изобретение относитс  к теплообменной аппаратуре и может быть испол зовано в энергетической промышленнос ти. Известны способы интенсификации теплообмена в трубчатом теплообменнике путем периодического изменени  расхода теплоносител  при его принудительном прокачивании по трубам L1J Недостатком указанного способа  вл етс  низкий коэффициент теплопередачи . Цель изобретени  - интенсификаци  теплообмена. Указанна  цель достигаетс  тем, что при нагреве теплоносител  изменение его расхода ведут путем чередо вани  скачкообразного уменьшени  с плавным увеличением, а при охлаждении - плавного уменьшени  со скачкообразным увеличением. На фиг. 1 представлены графики изменени  коэффициента теплоотда14И oL и расхода G теплоносител  при его охлаждении; на фиг. 2 - то же, при его нагреве; на фиг. 3 устройство , осуществл ющее предлагаемый способ. Устройство содержит распределительный диск 1, регулирующий расход теплоносител  в теплообменной трубе 2. Вращением диска 1 в ту или иную сторону осуществл етс  необходимый закон изменени  расхода теплоносители в трубе The invention relates to heat exchange apparatus and can be used in the energy industry. Methods are known for intensifying heat transfer in a tubular heat exchanger by periodically changing the flow rate of the heat transfer fluid when it is forcedly pumped through pipes L1J. The disadvantage of this method is the low heat transfer coefficient. The purpose of the invention is to intensify heat transfer. This goal is achieved by the fact that when the heat carrier is heated, the change in its flow rate is carried out by alternating a stepwise decrease with a gradual increase, and on cooling, a gradual decrease with a stepwise increase. FIG. Figure 1 shows the graphs of the change in the heat transfer coefficient 14I oL and the flow rate G of the coolant when it is cooled; in fig. 2 - the same, when it is heated; in fig. 3 device carrying out the proposed method. The device contains a distribution disk 1 regulating the flow of coolant in the heat exchange pipe 2. Rotating the disk 1 in one direction or another, the necessary law of changing the flow of heat transfer media in the pipe 2. При этом, сохран   средний расход теплоносител  G, средний коэффициент теплоотдачи /(-.р возрастает по сравнению сосоП|зи течении теплоносител  с посто нным расходом G. Предлагаемый способ интенсификации теплообмена при неизменном сред- . нем расходе теплоносител  повышает коэффициент теплоотдачи, интенсифицирует теплообмен и уменьшает габариты в целом. Формула изобретени  Способ интенсификации теплообмена в трубчатом теплообменнике путем пе2. At the same time, maintaining the average flow rate of the coolant G, the average heat transfer coefficient () increases in comparison with the flow of heat transfer fluids with a constant flow rate G. The proposed method for intensifying heat exchange at a constant average heat flow rate increases the heat transfer coefficient and heat transfer and reduces overall dimensions.
