Изобретение относитс к области теплообменной техники и может быть использовано в регенераторах.The invention relates to the field of heat exchange technology and can be used in regenerators.
Известны регенеративные насадки воздухоподогревателей , например, газотурбинных регенераторов, содержащие пакет металлических пластин с оребрением 1.Known regenerative nozzles air heaters, for example, gas turbine regenerators, containing a package of metal plates with fins 1.
Недостатком известных насадок вл етс низка интенсивность теплообмена при ламинарном режиме.A disadvantage of the known nozzles is the low intensity of heat exchange in the laminar mode.
Целью изобретени вл етс интенсификаци теплообмена.The aim of the invention is to intensify heat transfer.
Дл достижени поставленной цели оребрение выполнено в виде полого змеевика П-образного сечени со сплющенными гибами , прикрепленными к пластинам.To achieve this goal, the fins are made in the form of a hollow serpentine with a U-shaped cross-section with flattened bends attached to the plates.
На фиг. 1 изображена насадка, поперечный разрез; на фиг. 2 - то же, вид сверху.FIG. 1 shows a nozzle, a cross-section; in fig. 2 - the same, top view.
Насадка состоит из илоских пластин 1, к которым прикреилены П-образные иолые змеевики 2. На участках входа и выхода газов змеевики 2 имеют сплющенные гибы 3 дл снижени гидравлического сопротивлени . Дистанци между плоскими пластинами 1 поддерживаетс посредством выштампованных выступов 4.The nozzle consists of silt plates 1, to which U-shaped Iolite coils 2 are attached. At the gas inlet and outlet sections, coil 2 have flattened bends 3 to reduce the flow resistance. The distance between the flat plates 1 is supported by the stamped protrusions 4.
Работа насадкп осуществл етс по обычному регенеративному принципу. Продукты сгоранн и воздух движутс в каналах насадки попеременно и в противоточном направлеиии . Поскольку локальные коэффициенты теплопередачи пластин 1 и змеевиков 2 отличаютс , диаметр змеевиков 2 выбираетс больше толщины пластин 1 наCTO .ibKO, чтобы процесс аккумул ции теила в пластпнах 1 и змеевиках 2 происходил при одних и тех же иерепадах температуры , что интеисифицирует теплопередачу в целом.The operation of the nozzle is carried out in the usual regenerative manner. Products are burned and air moves in the nozzle channels alternately and in countercurrent direction. Since the local heat transfer coefficients of the plates 1 and coils 2 are different, the diameter of the coils 2 is chosen greater than the thickness of plates 1 on the CTO .ibKO, so that the accumulation of teila in the plates 1 and coils 2 takes place at the same temperature levels, which intestinizes heat transfer in general.
