Abstract

Изобретение относятся к пластинчатым теплообменникам через которые происходит теплообмен между двумя средами (жидкостями или паром и жидкостью). Технические результаты: выравнивание гидродинамических параметров элементарных объемов охлаждаемой или нагреваемой жидкости в пространстве между соседними теплообменными пластинами по ширине пластины при их подходе от входного отверстия через распределительно-коллекторную часть к основной теплообменной части и повышение эффективности теплообмена между двумя средами. Пластинчатый теплообменник включает несколько собираемых в блок совместно с герметизирующими прокладками посредством стягивающих элементов через прижимные пластины с фитингами теплообменных пластин, содержащих основную теплообменную часть, расположенную между двумя распределительно-коллекторными частями, и отверстия, расположенные в угловых частях распределительно-коллекторных частей для обеспечения притока и оттока охлаждаемой или нагреваемой жидкости или пара, рифления для расположения герметизирующих прокладок теплообменной части, распределительно-коллекторных частей, вблизи отверстий, причем последние выполнены таким образом, чтобы обеспечить на входе в пространстве между соседними теплообменными пластинами по ширине пластины различное гидродинамическое сопротивление - с переменным шагом или пологостью.The invention relates to plate heat exchangers through which heat transfer occurs between two media (liquids or steam and liquid). Technical results: alignment of hydrodynamic parameters of elementary volumes of a cooled or heated fluid in the space between adjacent heat transfer plates across the width of the plate as they approach from the inlet through the distribution-collector part to the main heat exchange part and increase the efficiency of heat exchange between the two media. The plate heat exchanger includes several assembled into the unit together with sealing gaskets by means of tightening elements through pressure plates with fittings of heat transfer plates containing the main heat exchange part located between the two distribution and collector parts, and openings located in the corner parts of the distribution and collection parts to provide inflow cooling or heated liquid or steam outflow, corrugations for the arrangement of heat exchanger sealing gaskets nd part, distributor-collector part, near the holes, the latter being formed so as to provide at the inlet in the space between adjacent heat exchanger plates for plate width different flow resistance - variable pitch or canopy.
