Abanikazi be-Stubby sekuyisikhathi eside beyisinqumo esidumile uma kuziwa ekugcineni iziphuzo zipholile. Ivamise ukutholakala emicimbini yokuxhumana nabantu efana namaphathi, izoso nemicimbi yezemidlalo, la magajethi awusizo aklanyelwe ukugcina amathini namabhodlela efudumele, avimbele ukuthi angashisi ngokushesha. Kodwa ingabe umnikazi we-stubby uphila ngokuvumelana ne-hype? Ake singene sijule kusayensi nokusebenza okungemuva kwalezi zinsiza ezithandwayo.
Okokuqala nokubalulekile, ake sixoxe ngomklamo wobakaki abafushane. Ekwaziwa nangokuthi ama-coolers noma ama-koozies, lezi zintaba ngokuvamile zenziwa nge-neoprene, impahla yerabha yokwenziwa eyaziwa ngezici zayo ezinhle kakhulu zokuvikela ukushisa. I-Neoprene ine-thermal conductivity ephansi, okusho ukuthi ayikuvumeli ukushisa kudlule kalula. Lesi sakhiwo sidlala indima ebalulekile ekugcineni okuqukethwe kwekani noma ibhodlela kupholile isikhathi eside.
Umsebenzi oyinhloko wesitendi esiqinile ukwakha umgoqo phakathi kwesitsha sesiphuzo nendawo ezungezile. Impahla ye-neoprene ivala imbiza noma ibhodlela, isiza ukugcina izinga lokushisa elipholile ngokunciphisa ukudluliswa kokushisa okuvela emithonjeni yokushisa yangaphandle. Lokhu kufakwa kuwusizo ikakhulukazi ezindaweni ezifudumele noma ngesikhathi semisebenzi yangaphandle, kuvimbela iziphuzo ukuthi zingabi sivivi ngaphambi kokuba ziqedwe.
Omunye angase azibuze ukuthi asebenza kanjani la ma-stents aqinile. Ukuze ulinganise ukusebenza kahle kwaso, kuyadingeka ukuqonda izici ezithinta ukuthi isiphuzo sishisa ngokushesha kangakanani. Ukudluliswa kokushisa kwenzeka ngezinqubo ezintathu eziyinhloko: conduction, convection, kanye nemisebe. Ukwenziwa ukudlulisa ukushisa okuqondile ngokuthintana ngokomzimba, i-convection iwukudlulisa ukushisa ngokunyakaza koketshezi noma igesi, futhi imisebe ihilela ukudluliswa kokushisa ngamagagasi kagesi.
Omunye wemithombo ebaluleke kakhulu yokudlulisa ukushisa ukudluliswa kokushisa. Lapho isandla esifudumele siphethe isiphuzo esibandayo, ukushisa okuvela esandleni kudluliselwa ethini noma ebhodleleni, okwandisa izinga lokushisa. Isitendi esiqinile sisebenza njengesithiyo, esinciphisa ukuthintana kwezandla nesiqukathi. Ngenxa yalokho, ukuhanjiswa kuyehla futhi iziphuzo zihlala zipholile isikhathi eside.
I-Convection ingesinye isici esibalulekile okufanele sicatshangelwe. Uma imbiza noma ibhodlela libekwe endaweni evulekile, ukugeleza komoya kukhipha ukushisa ebusweni besitsha. Iabaphethe stubbyiningi lendawo engaphezulu ye.ithini noma ibhodlela, okunciphisa ukuchayeka kulokhu kugeleza komoya. Ngenxa yalokho, izinga lapho isiphuzo sishisa khona ngenxa ye-convection lihamba kancane kakhulu.
I-radiation, nakuba ingenawo amandla njengokuqhutshwa nokuhamba, nayo idlala indima ekudluliseni ukushisa. Lapho isitsha sichayeka elangeni, amaza kagesi akhishwa yilanga angafudumeza isiphuzo ngaphakathi. Isitendi esiqinile sinciphisa ukukhanya kwelanga okuqondile ngokunikeza umthunzi nokumboza ingaphezulu lembiza noma ibhodlela. Lokhu kunciphisa imiphumela yemisebe, kusize nakakhulu ukugcina iziphuzo zipholile.
Nakuba isayensi yabanikazi beziqu ezimfushane ibonakala iphakamisa ukuthi bayasebenza ngempela ekuvimbeleni iziphuzo ukuthi zishise ngokushesha, kubalulekile ukuqaphela ukuthi ukusebenza kwazo kuncike kwezinye izici zangaphandle. Isibonelo, uma isiphuzo sichayeka elangeni isikhathi eside, indawo yokumisa eqinile ingase ingasebenzi kahle ekushiseni. Futhi, ezimeni ezishisa kakhulu, abakaki abaqinile bangase bangasebenzi kahle ekushiseni.
Sekukonke, isitendi esiqinile sinomphumela obonakalayo wokuthi isiphuzo sakho sishisa ngokushesha kangakanani. Ngenxa yezinto ze-neoprene, izakhiwo zabo zokuvikela zinciphisa kakhulu ukudluliswa kokushisa ngokusebenzisa i-conduction, convection kanye nemisebe. Nakuba izitendi eziqinile zingase zingakwazi ukunqoba izimo ezibucayi zangaphandle noma ukugcina iziphuzo ezishisayo zibanda isikhathi eside, ngokuqinisekile zinikeza ukuthuthuka okuphawulekayo ekugcineni iziphuzo ezingeni lokushisa eliqabulayo.
