Inqubo yokukhiqiza i-heatpipe heatsinks

Ama-heatpipe ashisayoziyingxenye ebalulekile kumishini eminingi ye-elekthronikhi nezinhlelo zokuqeda ukushisa ngempumelelo.Inqubo yokukhiqiza yalawa ma-heatsink ibandakanya izinyathelo ezimbalwa eziyinkimbinkimbi nobuchwepheshe obuvumela ukudluliswa kokushisa okusebenzayo.Kulesi sihloko, sizocubungula imininingwane yenqubo yokukhiqiza i-heatsink ye-heatsink, sihlole izigaba ezihlukene ezihilelekile kanye nobuchwepheshe obusetshenzisiwe.

Ukuze uqonde inqubo yokukhiqiza yama-heatsink, kubalulekile ukuthi uqale uqonde ukuthi iyini ipayipi lokushisa.I-heatpipe iyishubhu evaliwe yethusi noma i-aluminium equkethe inani elincane loketshezi olusebenzayo, ngokuvamile amanzi, utshwala, noma i-ammonia.Incike ezimisweni zokushintsha kwesigaba kanye nesenzo se-capillary ukudlulisa ukushisa kahle kusuka emthonjeni wokushisa kuya ku-heatsink.

Isinyathelo sokuqala senqubo yokukhiqiza ama-heatsink amapayipi okushisa ukwakhiwa kwamapayipi okushisa ngokwawo.Izinto ezisetshenziswayo ngokuvamile ziyithusi ngenxa ye-thermal conductivity yayo enhle kakhulu.Kunezindlela ezimbili eziyinhloko ezisetshenziselwa ukukhiqiza amapayipi okushisa: indlela ye-gravity kanye nendlela yokucwilisa.

Ngendlela ye-gravity, ipayipi lethusi elide, elingenalutho ligcwaliswa ngoketshezi olukhethiwe olusebenzayo, okushiya indawo encane ekugcineni ukuze kungene umhwamuko.Iziphetho zepayipi lokushisa zibe sezivalwa, futhi ipayipi liyakhishwa ukuze kukhishwe noma yimuphi umoya noma ukungcola.I-heatpipe ibe isishisiswe ngakolunye uhlangothi ukuze ibangele uketshezi ukuba luhwamuke, okwenza ingcindezi ngaphakathi kweshubhu.Lokhu kucindezela kubangela ukuba umhwamuko ugeleze uye ngasekugcineni okupholile, lapho ujiya khona futhi ubuyele ekugcineni kwasekuqaleni ngesenzo se-capillary, uqhubekisele phambili umjikelezo.Ipayipi lokushisa libe selihlolelwa ukuvuza namandla emishini ngaphambi kokudlulela esinyathelweni esilandelayo.

Indlela ye-sintering, ngakolunye uhlangothi, ihlanganisa ukuhlanganisa ithusi noma impushana ye-aluminium ibe sesimweni esifiswayo sepayipi lokushisa.Le mpushana ibe isishisiswe ize ishunqe ndawonye, ​​yakhe isakhiwo esiqinile, esinezimbotshana.Okulandelayo, uketshezi olusebenzayo lwengezwa ngokulujova esakhiweni esinezimbotshana noma ngokucwilisa ipayipi lokushisa oketshezini ukuze lukwazi ukungena entweni enezimbotshana.Ekugcineni, i-heatpipe iyavalwa, iyakhishwa, futhi ihlolwe njengoba kushiwo endleleni yamandla adonsela phansi.

Uma amapayipi okushisa enziwe, adlulela esigabeni esilandelayo senqubo yokukhiqiza, okubandakanya ukuwanamathisela kuma-heatsink.I-heatsink, evame ukwenziwa nge-aluminium noma ngethusi, inesibopho sokuqeda ukushisa okudluliselwa ngamapayipi okushisa.Kunezindlela ezahlukahlukene ezisetshenziswayo ukunamathisela amapayipi okushisa ku-heatsink, kufaka phakathi i-soldering, i-brazing, kanye ne-thermal adhesive bonding.

I-soldering iyindlela evame ukusetshenziswa ehlanganisa ukufaka i-solder paste ezindaweni ezithintana namapayipi okushisa kanye ne-heatsink.Amapayipi okushisa abe esebekwa ku-heatsink, futhi ukushisa kusetshenziswa ukuncibilikisa isolder, kudala isibopho esiqinile phakathi kwezingxenye ezimbili.I-Brazing iyinqubo efanayo ne-soldering kodwa isebenzisa izinga lokushisa eliphezulu ukuncibilikisa into yokugcwalisa eyenza isibopho phakathi kwamapayipi okushisa kanye ne-heatsink.I-thermal Adhesive bonding, ngakolunye uhlangothi, ihilela ukusebenzisa izinamathiselo ezikhethekile ezinezakhiwo eziphezulu ze-thermal conductivity ukunamathisela amapayipi okushisa ku-heatsink.Le ndlela iwusizo ikakhulukazi lapho usebenza nama-heatsink amise okwezimo eziyinkimbinkimbi.

Uma amapayipi okushisa enamathiselwe ngokuvikelekile ku-heatsink, umhlangano uhlolwa ukusebenza okushisayo nobuqotho bemishini.Lezi zivivinyo ziqinisekisa ukuthi amapayipi okushisa kanye ne-heatsink adlulisa ukushisa ngempumelelo futhi angakwazi ukumelana nezimo zokusebenza azobhekana nazo.Uma kutholwa noma yiziphi izinkinga noma ukukhubazeka ngesikhathi sokuhlolwa, umhlangano ubuyiselwa emuva ukuze kusetshenzwe kabusha noma kulahlwe, kuye ngobunzima benkinga.

Isigaba sokugcina senqubo yokukhiqiza sibandakanya ukuqeda kanye nokwelashwa okungaphezulu kwamaheatsink epayipi lokushisa.Lesi sinyathelo sihlanganisa izinqubo ezifana nokupholishwa, ukugcotshwa kwe-anodizing, noma ukumboza indawo ye-heatsink ukuze kuthuthukiswe amandla ayo okukhipha ukushisa, ukuthuthukisa ukumelana nokugqwala, noma ukuzuza isiphetho sobuhle.Ukukhethwa kokuqeda kanye nokwelashwa kwendawo kuncike ezidingweni ezithile kanye nezintandokazi zohlelo lokusebenza noma ikhasimende.

Sengiphetha, inqubo yokukhiqiza ama-heatsink epayipi yokushisa iyinqubo eyinkimbinkimbi nenembayo ebandakanya izinyathelo ezibalulekile nobuchwepheshe.Kusukela ekwenziweni kwamapayipi okushisa kuya ekuwanamathisele ku-heatsink futhi aqedele umhlangano, isigaba ngasinye sidlala indima ebalulekile ekuqinisekiseni ukudluliswa kokushisa okusebenzayo nokuqina kwe-heatsink.Njengoba amadivaysi e-elekthronikhi nezinhlelo ziqhubeka nokuvela futhi zidinga ukusebenza kahle kokushisa okuphezulu, inqubo yokukhiqiza ama-heatsink epayipi lokushisa izoqhubeka nokuthuthuka, yamukela amasu amasha nezinto zokwakha ukuhlangabezana nezidingo ezikhulayo zomkhakha.
