Description

(54) ТЕПЛООБМЕННИК(54) HEAT EXCHANGER

Изобретение относитс к аппаратам. которые могут быть использованы в любой отрасли промышленности.This invention relates to apparatus. which can be used in any industry.

Известен теплообменник, содержащий концентрично расположенные трубы , образующие кольцевые каналы дл теплообменивакнцихс сред, и концевые распределительные камеры с подвод щими и отвод щими полост ми, образованными раэделительныкт перегородками 1.A heat exchanger is known, which contains concentrically arranged tubes forming annular channels for heat exchange media, and end distribution chambers with supply and discharge cavities formed by separation partitions 1.

Недостаток теплообменника заключаетс в трудоемкости монтажно-демонтажных работ вследствие наличи значительного количества сварных швов и крепежных элементов.The lack of a heat exchanger lies in the laboriousness of the assembly and disassembly work due to the presence of a significant number of welds and fasteners.

Известен теплообменник, содержащий корпус с крышками по торцам и коаксиально установленные внутри корпуса цилиндры, жестко соединенные один с другим с образованием зигзагообразных циркул ционных каналов дл рабочих сред, подключенных к соответствук цему коллектору, и направл юпше элементы, установленные в каналах t 2.A heat exchanger is known, comprising a housing with covers along the ends and cylinders coaxially mounted inside the housing, rigidly connected to one another to form zigzag circulation channels for working media connected to the corresponding collector, and guides the elements installed in the channels t 2.

Недостаток данного теплообменника заключаетс также в трудоемкости его изготовлени и, кроме того, в низкоэффективном теплообмене между теплообменивающимис средами.The disadvantage of this heat exchanger is also in the complexity of its manufacture and, in addition, in the inefficient heat exchange between the heat exchanging media.

Цель изобретени - интенсификаци теплообмена.The purpose of the invention is to intensify heat transfer.

Цель достигаетс тем, что в известном теплообменнике, содержащем корпус с крьааками по торцам и коаксиально установленные внутри корпуса цилиндры, жестко соединенные один с The goal is achieved by the fact that in a known heat exchanger comprising a housing with kraaks along the ends and cylinders coaxially mounted inside the housing, rigidly connected one

Claims

The heat exchanger includes a housing 1, covers 2 and 3, cylinders 4 coaxially mounted inside the housing, rigidly connected to each other with the formation of zigzag channels 5 and. 6 for working media connected, respectively, to collectors 7 and 8 for supplying media to collectors 9 and 10 for their removal, directed to these elements 11, fitted with fins 12 attached to the walls of cylinders 4, partitions 13 and 14 attached to covers 2 - and 3, respectively, the central cylinder 15. Peregorodki 13 and 14 are provided with grooves 16 under the cylinders. The housing is equipped with a pipe 17 and 18 for the supply of media, a patent 19 and 20 for their removal. The heat exchanger operates as follows. The working media through the pipes 17 and 18 and the collectors 7 and 8 enter channels 5 and b, respectively. After heat exchange through the walls of the cylinders, one of the media, cooled, is discharged through pipe 19, the other through pipe 20 {heated. The described heat exchanger is simple to manufacture, due to which it is possible to simplify installation and dismantling works. Claims of the Invention A heat exchanger comprising a case with lids on the ends and cylinders coaxially mounted inside the case, rigidly connected to one another with the formation of zigzag circulation channels for working media connected to the respective collectors and directional elements installed in the channels that differ in order to intensify the heat exchange, the guide elements are rigidly attached to the walls of the cylinders, and the collectors are separated by a partition attached to the covers and the central cylinder friend and having grooves under the cylinders.
