Ukushisa okushisayo kuyisici esibalulekile sezinto ezisetshenziswa ezimbonini ezahlukene, ikakhulukazi kwezobuchwepheshe kanye nokuphathwa kokushisa.Ama-thermal padIkakhulukazi, idlala indima ebalulekile ekuqedeni ukushisa okuvela ezingxenyeni zikagesi ukuqinisekisa ukusebenza kahle kanye nobude besikhathi. Ukuqinisekisa ukusebenza kahle kwama-thermal pads, amazinga athile okuhlola ukuguquguquka kokushisa kumele alandelwe futhi izindlela zokuthola ezinembile kumele zisetshenziswe.
Izindinganiso zokuhlola ukuguquguquka kokushisa kwama-thermal pad zivame ukunqunywa izinhlangano zezimboni ezifana ne-ASTM International noma i-International Organisation for Standardization (ISO). Lezi zindinganiso zichaza izinqubo nezidingo zokuhlola ukuguquguquka kokushisa kwezinto, okuhlanganisaama-thermal padIndinganiso evamile yokuhlolwa kokushisa yi-ASTM D5470, enikeza isiqondiso sokulinganisa izakhiwo zokudlulisa ukushisa ezizinzile zezinto zokuvikela.
Ukwenza ukuhlolwa kokushisa kwe-thermal conductivityama-thermal pad, izindlela ezahlukahlukene zingasetshenziswa, okuhlanganisa indlela yemitha yokugeleza kokushisa evikelwe, indlela ye-Transient Plane Source (TPS), kanye nendlela ye-hot plate. Indlela ngayinye inezinzuzo kanye nemikhawulo yayo, futhi ukukhetha indlela kuncike ezintweni ezifana nezakhiwo zezinto, usayizi wesampula, kanye nezimo zokuhlola.
Indlela yemitha yokugeleza kokushisa evikelwe ihilela ukulinganisa ukugeleza kokushisa ngesampula ye-i-thermal padizinto ezibonakalayo, kuyilapho indlela yomthombo we-transient planar isebenzisa inzwa ukufaka i-heat pulse ezintweni ezibonakalayo nokukala impendulo yokushisa ukuze kubalwe i-thermal conductivity. Indlela ye-hot disk isebenzisa inzwa ukusebenzisa i-thermal pulse futhi ikala impendulo yokushisa ukuze inqume ngqo i-thermal conductivity yezinto ezibonakalayo.
Ngaphezu kokulandela amazinga okuhlola anqunyiwe nokusebenzisa izindlela zokuhlola ezifanele, kubalulekile futhi ukuqinisekisa ukunemba nokuthembeka kwezilinganiso zokushisa. Lokhu kungafezwa ngokulungiselela ngokucophelela amasampula, ukulinganisa imishini yokuhlola, kanye nokulandela izinqubo zokuhlola ezijwayelekile.
Ukuhlola ukuguquguquka kokushisa kwephedi yokushisa kudinga ukuhlaziya imiphumela yokuhlola etholwe endleleni yokuhlola ekhethiwe. Inani lokuguquguquka kokushisa limelela ikhono lezinto zokwakha lokuqhuba ukushisa, ngamanani aphezulu abonisa ukuguquguquka okungcono kokushisa. Kubalulekile ukuqhathanisa ukuguquguquka kokushisa okulinganisiwe kwephedi yokushisa nezidingo ezithile noma amazinga omkhakha ukuze kunqunywe ukuthi iyahlangabezana yini nezindinganiso zokusebenza ezidingekayo.
Kwezinye izimo,ama-thermal padbangase bahlolwe okwengeziwe ukuze bahlole ukusebenza kwabo kokushisa ngaphansi kwezimo ezithile zokusebenza, njengokushisa okukhulu noma ukucindezeleka komshini. Lokhu kungafaka ukuhlolwa kokujikeleza kokushisa, lapho i-thermal pad ibhekana nokushintsha okuphindaphindiwe kokushisa ukuze kuhlolwe ukuqina kwayo kokushisa nokuthembeka.
Ngaphezu kwalokho, intuthuko kwezobuchwepheshe iholele ekuthuthukisweni kwezindlela zokuhlola ezingonakalisi zokuqhuba ukushisa, njenge-infrared thermography kanye ne-thermal imaging. Lezi zindlela zivumela ukubona nokuhlaziya ukusatshalaliswa kokushisa ngaphakathi kwe-thermal pad, okuhlinzeka ngemininingwane ebalulekile ngokusebenza kwayo kokushisa ngaphandle kokushintsha noma ukulimaza impahla.
Ngamafuphi, amazinga okuhlola ukuguquguquka kokushisa kwama-thermal pads abalulekile ekuqinisekiseni ukusebenza kwawo kahle ekusetshenzisweni kokuphathwa kokushisa. Ngokulandela amazinga okuhlola amisiwe, besebenzisa izindlela zokuhlola ezinembile, futhi behlaziya imiphumela yokuhlola ngokuphelele, abakhiqizi nonjiniyela bangaqinisekisa ukusebenza kokushisa kwama-thermal pads futhi benze izinqumo ezinolwazi mayelana nokufaneleka kwawo ezinhlotsheni ezithile. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukuthuthukiswa kobuchwepheshe bokuhlola obusha kuzothuthukisa kakhulu ikhono lokuthola nokuhlola ukuguquguquka kokushisa kwama-thermal pads, okunegalelo ekuthuthukisweni kwezixazululo zokuphathwa kokushisa ezimbonini ezahlukahlukene.
