I-Electronic Consumer

I-heater sink idlala indima ebalulekile ekulawuleni ukushisa okukhiqizwa izinto zikagesi noma zemishini, iqinisekisa ukuthi zisebenza ngaphakathi kwemikhawulo yazo yezinga lokushisa ephephile. Kuyisishintshi sokushisa esingashintshisi esidlulisa ukushisa kusuka kudivayisi kuya endaweni ewuketshezi, njengomoya noma into epholisayo ewuketshezi, lapho ingahlakazwa khona ngempumelelo.

Kumongo wamakhompyutha, osinki bokushisa bavame ukusetshenziselwa ukupholisa amayunithi okucubungula amaphakathi (CPUs), amayunithi okucubungula ihluzo (GPUs), ama-chipset, namamojula we-RAM. Lezi zingxenye zivame ukukhiqiza inani elikhulu lokushisa ngesikhathi sokusebenza, futhi ngaphandle kokupholisa okufanele, zingashisa ngokushesha, okuholela ekonakaleni kokusebenza noma ngisho nokuhluleka kwengxenye. Idizayini nokwakhiwa kosinki wokushisa kubalulekile ukuze kukhishwe ukushisa ngendlela efanele. Amasinki amaningi okushisa asebenzisa isakhiwo esicijile esenziwe ngezinto ezihambisa ukushisa njenge-aluminium noma ithusi. Amaphiko akhulisa indawo engaphezulu yesinki wokushisa, okuvumela ukuthintana okukhulu nendawo ewuketshezi ezungezile futhi kuthuthukise ukudluliswa kokushisa. Uma idivayisi ye-elekthronikhi isebenza, ukushisa kukhiqizwa ezingeni lengxenye, njenge-CPU noma i-GPU. Ukushisa kuqhutshwa ngomzimba wedivayisi, futhi ukuvimbela ukushisa ngokweqile, kudinga ukuchithwa endaweni ezungezile. Yilapho i-heater sink ingena khona. Umshini wokushisa unamathele engxenyeni eshisayo, esebenza njengendlela yokushisa ukuze ukushisa kugeleze kusuka engxenyeni kuya endaweni yokushisa. Uma ukushisa sekudluliselwe kusinki wokushisa, kudinga ukuchithwa ngokuphumelelayo ukuze kugcinwe izinga lokushisa ledivayisi ngaphakathi kwemikhawulo ephephile. Ukupholisa komoya kuyindlela evame kakhulu, lapho usinki wokushisa uvezwa emoyeni ozungezile. Indawo enkulu yamaphiko okushisa okushisa ivumela ukuchithwa okuphumelelayo kokushisa ngokusebenzisa i-convection. Umoya ozungezile udonsa ukushisa futhi ukuhambise, upholise isinki sokushisa kanye nengxenye enamathiselwe. Kuzinhlelo zokusebenza ezidinga kakhulu noma lapho usebenza nemithwalo yokushisa ephezulu kakhulu, ukupholisa uketshezi kungasetshenziswa. Isipholile esiwuketshezi sizungeza kusinki wokushisa, sibambe ukushisa, bese sikuthwala sikuyise kurediyetha lapho singachithwa khona. Ukupholisa uketshezi kunikeza i-thermal conductivity ephezulu kunokupholisa komoya, okuvumela ukulahlwa kokushisa okuthuthukisiwe kanye namazinga okushisa okungenzeka aphansi okusebenza. Amasinki okushisa awagcini kumakhompyutha; ziphinde zisetshenziswe kakhulu kumadivayisi we-semiconductor enamandla amakhulu njengama-transistors amandla, ama-laser, nama-LED. Lawa madivayisi akhiqiza ukushisa okuphawulekayo ngesikhathi sokusebenza, futhi ngaphandle kokuphathwa kokushisa okuphumelelayo, ukusebenza kwawo nokuthembeka kungase kube sengozini. Osinki bokushisa kulezi zinhlelo zokusebenza ngokuvamile badizayinelwe ngokwezifiso ukuze bahlangabezane nezimfuneko ezithile zokushisa zedivayisi.

Sengiphetha, amasinki okushisa ayizingxenye ezibalulekile ezinhlelweni zikagesi nezemishini, ezilawula izinga lokushisa lamadivayisi ngokudlulisa kahle nokukhipha ukushisa. Kungakhathaliseki ukuthi kumakhompuyutha, ama-power transistors, noma ama-optoelectronics, osinki bokushisa badlala indima ebalulekile ekugcineni ukusebenza kwedivayisi, ukuvimbela ukushisa ngokweqile, kanye nokuqinisekisa ubude besikhathi nokuthembeka kwezingxenye.
