Imiba ekufuneka iqwalaselwe kwiipleyiti zokutshintsha ubushushu

Uhlobo lwepleyiti okanye uhlobo lwamathanki kufuneka lugqitywe ngokweemfuno zangempela zesiganeko sokutshintshiselana kobushushu. Ukuhamba okukhulu kunye nokuhla kwengcinezelo encinci evumelekileyo, uhlobo lweplate kunye nokuchasana okuncinci kufuneka kukhethwe, kwaye ngokufanayo. Qinisekisa ukuba ukhetha uhlobo olunokuchithwa okanye uhlobo lwebrazed ngokoxinzelelo lwe-fluid kunye nobushushu. Xa umisela uhlobo lweplate, akucebisi ukuba ukhethe ipleyiti enendawo encinci yepleyiti enye, ukuze ugweme iiplati ezininzi, isantya esisezantsi kakhulu phakathi kwamacwecwe, kunye ne-coefficient yokudlulisa ubushushu obuphantsi kakhulu. Le ngxaki kufuneka ihlawulwe ingqwalasela ngakumbi kubatshintshi bobushushu abakhulu.
Ukuqukuqela kubhekiselele kwiqela lemijelo yokuhambahamba ehambelanayo kwicala lokuqukuqela elifanayo lendawo ephakathi kwipleyiti yokutshintshiselana kobushushu, kwaye umjelo wokuhamba ubhekisa kumjelo ophakathi wokuhamba owenziwe ngamacwecwe amabini akufuphi kwipleyiti yokutshintshisa ubushushu. Ngokubanzi, imijelo yokuhambahamba emininzi idityaniswe ngokunxuseneyo okanye ngokulandelelana ukwenza imidibaniso eyahlukeneyo yamajelo aphakathi abandayo nashushu.
Ukudityaniswa kokuhamba kufuneka kumiselwe ngokusekelwe kutshintshiselwano lobushushu kunye nokubala ukumelana nolwelo kunye naphantsi kweemeko zenkqubo yeentlanganiso. Zama ukwenza i-coefficients yokudlulisa ubushushu kwi-coefficients yamanzi abandayo kunye namanzi ashushu alinganayo okanye asondelelene ukuze ufumane isiphumo esihle sokudlulisa ubushushu. Ngenxa yokuba i-coefficient yokudlulisa ubushushu ifumana ixabiso elikhulu xa i-coefficients yokudlulisa ukushisa kwe-convection kumacala omabini omgangatho wokudlulisa ubushushu ilingana okanye ivaliwe. Nangona isantya sokuhamba phakathi kwamacwecwe e-plate heat exchanger ayilingani, i-avareji yesantya sokuhamba sisasetyenziselwa ukubala ukutshintshwa kobushushu kunye nokuxhathisa ulwelo. Ukusukela ukuba "U"{4}}imibhobho yokuhamba emile enye-emiliselwe kwi-clamping plate, kulula ukuyiqhaqha kwaye idibanise.
Kwi-design kunye nokukhethwa kwe-plate heat exchangers, kukho iimfuno ezithile ngokubanzi zokunciphisa uxinzelelo, ngoko kufuneka kuhlolwe. Ukuba ukuhla koxinzelelo olukhangelweyo kugqithise ukwehla koxinzelelo oluvumelekileyo, ubalo loyilo lokukhetha kufuneka lwenziwe kwakhona{1}}de iimfuno zenkqubo zifezekiswe.
