Description
раллельных каналов 12 и 13, концы которых подключены к паровым коллекторам 14 и 15 и жидкостным коллекторам 16 и 17, подсоединенным к контуру 9 напорными трубками 18 и 19, расположенными симметрично относительно контура 9 и под острым углом а к ней. Часть контура 9, предвключенна напорным трубкам 18 и 19, разделена на две параллельные ветви 20 и 21 с кожухами 22 и 23, в которые соответственно помещены зоны 5 и 6 конденсации и жидкостные коллекторы 16 и 17.parallel channels 12 and 13, the ends of which are connected to steam manifolds 14 and 15 and liquid collectors 16 and 17 connected to circuit 9 by pressure tubes 18 and 19, located symmetrically with respect to circuit 9 and at an acute angle a to it. The part of circuit 9, pre-connected to pressure tubes 18 and 19, is divided into two parallel branches 20 and 21 with housings 22 and 23, in which condensation zones 5 and 6 and liquid collectors 16 and 17 are respectively placed.
Теплопередающее устройство работает следующим образом.Heat transfer device operates as follows.
К зонам 3 и 4 испарени подводитс тепловой поток, вызывающий кипение жидкости (т. е. жидкого теплоносител ), образовавшийс пар выталкивает жидкость в зоны 5 и 6 конденсации и через напорные трубки 18 и 19 в контур 9. При попадании пара в зоны 5 и 6 конденсации давление в каналах 12 и 13 падает и жидкость из контура 9 под действием более высокого давлени в зоне подключени напорных трубок 18 и 19 возвращаетс в зоны 3 и 4 испарени . Выталкивание паром жидкости в трубах 1 и 2 происходит не одновременно , а поочередно, в установившемс режиме термоавтоколебаний. Порции жидкости, попадающие из напорных трубок 18 и 19 в контур 9, сообщают свой импульс наход щейс там жидкости, вызыва ее непрерывную циркул цию. Жидкость охлаждаетс в теплообменнике-охладителе И и, протека через кожухи 22 и 23, отбирает тепло от зон 5 и 6 конденсации и жидкостных коллекторов 16 и 17. Дополнительный подогрев жидкости в контуре производитс в теплообменнике-нагревателе 10, который может быть установлен или на участке подвода тепла к зонам 3 и 4 испарени (как показано на чертеже) или на другом участке контура 9.Heat flow is supplied to the evaporation zones 3 and 4, which cause boiling of the liquid (i.e., the heat-transfer fluid), the generated vapor pushes the liquid into the condensation zones 5 and 6 and through the pressure pipes 18 and 19 into the circuit 9. When steam enters the zones 5 and 6, the condensation pressure in the channels 12 and 13 drops and the liquid from the circuit 9 under the action of a higher pressure in the connection zone of the pressure pipes 18 and 19 returns to the evaporation zones 3 and 4. Steaming of the liquid in pipes 1 and 2 does not occur simultaneously, but in turn, in the established mode of thermo-oscillations. The portions of the fluid that fall from the pressure pipes 18 and 19 into circuit 9 communicate their impulse to the fluid there, causing its continuous circulation. The liquid is cooled in the heat exchanger-cooler And, and flowed through the housings 22 and 23, takes heat from condensation zones 5 and 6 and liquid collectors 16 and 17. Additional heating of the fluid in the circuit is carried out in the heat exchanger-heater 10, which can be installed or on the site heat supply to the evaporation zones 3 and 4 (as shown in the drawing) or in another part of circuit 9.
