Abatshintshi bobushushu beSpiral zizixhobo ezisebenza kakuhle kakhulu zokutshintshiselana ngobushushu. Ulwakhiwo lwazo olukhethekileyo lwe-spiral lubonelela ngeenzuzo ezibalulekileyo ekusebenzeni kobushushu, ukubumbana, kunye nokuhambelana kolwelo. Eli nqaku liza kuphonononga iindlela zokuyila kunye namanqaku aphambili okutshintsha ubushushu obujikelezayo kwizicelo ezisebenzayo.
Isakhiwo esingundoqo se-spiral heat exchanger siquka iiseti ezimbini zemijelo ejikelezayo. Ulwelo olushushu nolubandayo luhamba ngokuphikisanayo okanye ngaxeshanye ngaphakathi kwemijelo, lutshintshisa ubushushu ngeendonga zentsimbi. Uyilo lwayo lubeka phambili ukuguquguquka kwamanzi kunye nokusebenza kakuhle kokudluliselwa kobushushu. Okokuqala, i-diameter kunye ne-pitch ye-spiral channels ichaphazela ngokuthe ngqo ukuxhathisa ukuhamba kunye nommandla wokudlulisa ubushushu. I-pitch encinci yongeza indawo yokudlulisa ubushushu kodwa inokonyusa ukumelana nokuhamba. Ke ngoko, ii-computational fluid dynamics (CFD) ukulinganisa kuyafuneka ukuze kuphuculwe ijiyometri yetshaneli. Okwesibini, ukukhetha izinto eziphathekayo kubalulekile. I-Corrosion esetyenziswa ngokuxhaphakileyo{7}}izinto ezixhathisayo ezifana nentsimbi estainless kunye ne-titanium alloys zilungele{8}}ubushushu obuphezulu,{9}}uxinzelelo oluphezulu, okanye usetyenziso lwemidiya edlekayo.
Ngokuphathelele kwimveliso, abatshintshi bobushushu be-spiral bahlala besebenzisa i-coil welding okanye i-hydroforming ukuqinisekisa ukutywinwa kunye namandla okwakhiwa kweetshaneli ezijikelezayo. Inkqubo ye-welding idinga ulawulo olungqongqo lwegalelo lokushisa ukuphepha ukuguqulwa kwezinto kunye ne-intergranular corrosion. Ngaphezu koko, indlela yokufakela i-spiral heat exchanger nayo ichaphazela ukusebenza kwayo. Ukuba uyifake ngokuthe tye okanye ngokuthe nkqo kuxhomekeke kwiimpawu zolwelo kunye neemfuno zokulondolozwa.
Ngokubhekiselele kwisicelo, abatshintshi bobushushu be-spiral basetyenziswa kakhulu kwiikhemikhali, i-petroleum, ukusetyenzwa kokutya, kunye neenkqubo ze-HVAC. Uyilo lwazo olubambeneyo lufanelekile ngokukodwa kwisithuba{1}}usetyenziso olubambeneyo, ngelixa isiphithiphithi sazo esikhulu sinciphisa ngokufanelekileyo isikali kwaye kwandisa ubomi besixhobo. Ngexesha lokusebenza, ukucoca rhoqo kunye nokugcinwa ngundoqo ekuqinisekiseni ixesha elide, ukusebenza kakuhle.
Isishwankathelo, abatshintshisi bobushushu be-spiral, kunye nokusebenza kwabo okusebenzayo kokufudumeza ubushushu kunye nokuguquguquka okuguquguqukayo, baye baba lukhetho olubalulekileyo kutshintshiselwano lobushushu lwanamhlanje. Uyilo olunengqiqo kunye nokugcinwa kwenzululwazi kunokwandisa ngakumbi ukuthembeka kunye neendleko{1}}ezisebenzayo.
