Description
(54) ТЕПЛООБМЕННЫЙ ЭЛЕМЕНТ ПЛАСТИНЧАТОГО (54) HEAT EXCHANGE ELEMENT PLATE
1one
Изобретение относитс к теплообменным элементам пластинчатых теплообменников и может быть использовано в химическом и энергетическом машиностроении.The invention relates to heat exchange elements of plate heat exchangers and can be used in chemical and power engineering.
Известны теплообменные элементы пластинчатых теплообменников, содержащие плоские пластины и размещенные между ними с зазорами между собой секции гофрированных вставок, образующих с пластинами каналы дл рабочей среды 1.Heat transfer elements of plate heat exchangers are known, containing flat plates and sections of corrugated inserts arranged between them with gaps between them, which form channels for the working medium 1 with the plates.
Недостатком этих элементов вл етс относительно невысока интенсивность теплообмена .The disadvantage of these elements is the relatively low intensity of heat exchange.
Цель изобретени - интенсификаци теплообмена.The purpose of the invention is to intensify heat transfer.
Указанна дель достигаетс тем, что между пластинами вдоль движени рабочей среды установлена зигзагообразна разделительна перегородка с чередующимис пр мыми участками различной длины, образующа с пластинами диффузорно-конфузорные зоны и раздел юща секции вставок на части, размещенные в диффузорных зонах по обе стороны каждого из больщих участков перегородки, причем каналы, образованные вставками, выполнены расшир ющиТЕПЛООБМЕННИКАThis del is achieved by the fact that a zigzag dividing partition with alternating straight sections of different lengths is formed between the plates along the movement of the working medium, forming diffuse-confused zones with the plates and dividing the insert sections into parts located in diffuse zones on both sides of each of the large sections partitions, and the channels formed by the inserts, made expanding HEAT EXCHANGER
мис по ходу рабочей среды и имеют угол раскрыти и длину, не превыщающие соответственно 10° и 100 da, где ds - эквивалентный гидравлический диаметр канала на входе в него среды.MIS along the working medium and have an opening angle and length not exceeding 10 ° and 100 da, respectively, where ds is the equivalent hydraulic diameter of the channel at the entrance of the medium.

Элемент содержит плоские пластины 1 и размещенные между ними с зазорами между собой секции гофрированных вставок 2, образующих с пластинами 1 каналы дл рабочей среды. Между пластинами 1 вдоль движени рабочей среды установлена зигзагообразна разделительна перегородка 3 с чередующимис пр мыми участками различной длины, образующа с пластинами 1 The element contains flat plates 1 and placed between them with gaps between themselves sections of corrugated inserts 2, which form channels with working plates for plates 1. Between the plates 1 along the movement of the working medium there is a zigzag dividing partition 3 with alternating straight sections of different lengths, forming plates 1
15 диффузорно-конфузорные зоны и раздел юща секции вставок 2 на части, размещенные в диффузорных зонах по обе стороны каждого из больших участков перегородки 3, причем каналы, образованные вставками15 diffuse-confused zones and separating sections of the inserts 2 into parts placed in diffuser zones on both sides of each of the large portions of the partition 3, with the channels formed by the inserts
