Igobolondo kunye ne-tube exchanger heat inamacandelo afana negobolondo, i-tube yokuhambisa ubushushu, i-tube plate, i-baffle plate (i-baffle), kunye nebhokisi ityhubhu. Igobolondo ininzi i-cylindrical, kunye ne-bundle yeepayipi ezifakwe ngaphakathi, kwaye iziphelo ezimbini ze-bundle zigxininiswe kwi-tube plate. Kukho iindidi ezimbini zolwelo lokutshintshiselana kobushushu: kubanda kunye kushushu. Enye iqukuqela ngaphakathi kwityhubhu kwaye ibizwa ngokuba yi-tube side fluid; Olunye uhlobo lokuqukuqela ngaphandle kombhobho lubizwa ngokuba lulwelo olusecaleni kweqokobhe. Ukuphucula i-coefficient yokudlulisa ubushushu be-fluid ngaphandle kombhobho, ii-baffles ezininzi zihlala zifakwe ngaphakathi kwigobolondo. I-Baffles inokunyusa isantya solwelo kwicala leqokobhe, ukunyanzela ulwelo ukuba ludlule kwinqwaba yetyhubhu amaxesha amaninzi ngokwendlela ekhankanyiweyo, kunye nokuphucula inqanaba lokuphazamiseka kolwelo. Iityhubhu zokutshintshiselana ngobushushu zinokucwangciswa koonxantathu abalinganayo okanye izikwere kwipleyiti yombhobho. Ulungelelwaniso lwenxantathu olulinganayo luncinci, kunye neqondo eliphezulu le-turbulence kumanzi ngaphandle kombhobho kunye ne-coefficient yokudlulisa ukushisa okukhulu; Ilungiselelo lesikwere lenza ukucocwa ngaphandle kombhobho kube lula kwaye kukulungele ulwelo olulungele ukulinganisa.

Iiparamitha eziphambili zokulawula igobolondo kunye ne-tube yokutshintshiselana kobushushu yindawo yokufudumeza, izinga lokuhamba kwamanzi ashushu, amandla okutshintsha ubushushu, kunye neeparitha eziphakathi kobushushu.

Ngalo lonke ixesha ulwelo ludlula kumbhobho, lubizwa ngokuba yityhubhu yokudlula; Indlela nganye kwiqokobhe ibizwa ngokuba kukudlula kweqokobhe. Umzobo ubonisa elona qokobhe lilula kunye netyhubhu enye yokutshintshiselana kobushushu, efinyeziweyo njenge-Type 1-1 yokutshintsha ubushushu. Ukuphucula isantya samanzi ngaphakathi kombhobho, i-baffles inokufakwa ngaphakathi kweziphelo ezimbini zebhokisi yombhobho ukwahlula yonke imibhobho ibe ngamaqela amaninzi. Ngale ndlela, ulwelo ludlula kuphela kwinxalenye yetyhubhu ngexesha ngalinye, ngoko luhamba lubuye luphinde lubuye izihlandlo ezininzi ngaphakathi kwinyanda yetyhubhu, ebizwa ngokuba yi-multi tube pass. Ngokufanayo, ukunyusa isantya sokuhamba ngaphandle kombhobho, i-longitudinal baffles inokufakwa ngaphakathi kwiqokobhe ukunyanzela ulwelo ukuba ludlule kwindawo yeqokobhe amaxesha amaninzi, olwaziwa ngokuba zii-multiple shell passes. Iityhubhu ezininzi kunye neenkqubo ezininzi zeqokobhe zingasetyenziswa ngokudibeneyo.

1. Ukusebenza ngokufanelekileyo kunye nokugcina amandla, i-coefficient yokudlulisa ukushisa kwesi sixhobo sokushisa ngu-6000-8000W / m2.0C.

2. Yenziwe ngayo yonke insimbi engenasici, kunye nobomi benkonzo ende kwiminyaka engama-20.

3. Ukutshintsha ukuhamba kwe-laminar kwi-turbulence kuphucula ukuhanjiswa kobushushu kunye nokunciphisa ukuxhathisa kwe-thermal.

4. Isantya sokutshintsha ubushushu obukhawulezayo, ukumelana nobushushu obuphezulu (400 ℃), kunye nokumelana noxinzelelo oluphezulu (2.5Mpa).

5. Ubume obubambeneyo, unyawo oluncinci, ubunzima obulula, ufakelo olulula, kunye nokonga kutyalo-mali lobunjineli boluntu.

6. Uyilo oluguquguqukayo, iinkcukacha ezipheleleyo, ukusebenza okuqinileyo kunye nokujolisa, ukonga imali.

7. Inoluhlu olubanzi lweemeko zesicelo kwaye ifanelekile kuluhlu olukhulu loxinzelelo kunye nobushushu, kunye nokutshintshwa kobushushu kwiimidiya ezahlukeneyo.

8. Iindleko zokugcinwa okuphantsi, ukusebenza lula, umjikelezo omude wokucoca, kunye nokucoca okulula.

9. Ukusetyenziswa kweteknoloji yefilimu ye-nano thermal kwandisa kakhulu i-coefficient yokudlulisa ukushisa.

10. Inemimandla ebanzi yesicelo kwaye inokusetyenziswa ngokubanzi kwiinkalo ezifana namandla ashushu, iifektri kunye nemigodi, imboni yepetrochemical, ukufudumeza okuphakathi kwedolophu, ukutya kunye namayeza, i-electronics energy, oomatshini kunye noshishino olulula, njl.

11. I-tube yokudlulisa ubushushu ithatha iibhubhu zethusi ezinama-fins aqengqiwe kwindawo yangaphandle, ene-conductivity ephezulu ye-thermal kunye nommandla omkhulu wokushisa ukushisa.

12. Ipleyiti yesikhokelo ikhokela i-shell side fluid ukuba ihambe ngokuqhubekayo kwi-zigzag shape ngaphakathi kwe-heat exchanger, kwaye isithuba phakathi kweeplate zesikhokelo sinokuhlengahlengiswa ngokwezinga eliphezulu lokuhamba. Ulwakhiwo lomelele kwaye lunokuhlangabezana neemfuno zokuhambisa ubushushu bolwelo olusecaleni kweqokobhe olunamazinga aphezulu okuqukuqela, namazinga okuqukuqela amakhulu kakhulu, kunye nezandi zokuphefumla eziphezulu.

13.Xa i-shell side yeqokobhe ioli, ifanelekile ukutshintshana kobushushu be-viscosity ephantsi kunye neoli ecocekileyo.
