Description
(54) КОЖУХОТРУБНЫЙ ТЕПЛООБМЕННИК(54) SHELL-TUBE HEAT EXCHANGER
Изобретение относитс к теплообменным аппаратам и может быть применено в энергетической промышленности. Известен теплообменник, на теплоотвод щих поверхност х которого размещено , пористое покрытие. В таком теп лообменнике процесс теплообмена интенсифицируетс в два - три раза за счет микроконвекции и эжекции в капилл рных каналах пористого покрыти D- Недостатком указанного теплоойу1енника вл етс большое гидравлическое, сопро тивление. Известен кожухотрубный теплообменник , внутри которого проход т каналы в виде последовательно чередующихс диффузорных и конфузорных участков с теплоотдающими и тепловоспринимающими поверхност ми Г21. В таком теплообменнике интенсивност теплоойу1ена повышаетс благодар вне- сению в поток неоднородностей по давлению , что приводит к турбулизации потока Недостатком указанного теплообмен- ника вл етс большое гидравлическое сопротивление.. Целью изобретени вл етс уменьшение гидравлического сопротивлени при , одновременной интенсификации теплообмена . Эта цель достигаетс т&л, что на теплоотдающих. поверхност х диффузорн: 1Х участков каналов размещено пористое покрытие, капилл ры которого расположены перпендикул ркЕо поверхности диффузорного участка. На фиг. I изображен ойций вид кожухе трубного теплообу1еннйка на фиг. 2 - диффузорные и конфузорные участки канала. Внутри корпуса I проход т каналы 2 в виде последовательно чередующихс диффузорных 3 и конфузорных 4 участков. На теплоотдающей поверхности диффузорных участков каналов размешево пористое покрытие 5, капилл ры котороThe invention relates to heat exchangers and can be applied in the energy industry. A heat exchanger is known, on which heat-removing surfaces a porous coating is placed. In such a heat exchanger, the heat exchange process is intensified by two to three times due to microconvection and ejection of porous coating in the capillary channels. D- The disadvantage of this heat sink is a large hydraulic resistance. A shell-and-tube heat exchanger is known, inside of which channels are passed in the form of successively alternating diffuser and confused sections with heat-transfer and heat-receiving surfaces G21. In such a heat exchanger, the intensity of heat recovery increases due to the introduction of pressure irregularities into the flow, which leads to turbulence in the flow. The disadvantage of this heat exchanger is a large hydraulic resistance. This goal is achieved t & that on the heat. surfaces diffuser: 1X sections of channels placed a porous coating, the capillaries of which are located perpendicular to the surface surface of the diffuser section. FIG. I shows the view of the casing of the tube heat exchanger in FIG. 2 - diffuser and confused sections of the channel. Channels 2 are arranged inside the housing I in the form of successively alternating diffuser 3 and confused 4 sections. On the heat-release surface of the diffuser sections of the channels there is a mixed porous coating 5, the capillary tubes of which
