Inkqubo yokuvelisa i-heatpipe heatsinks

Iiheatsinks zombhobho wobushushuziyingxenye ebalulekileyo kwizixhobo ezininzi zombane kunye neenkqubo zokuchitha ubushushu ngokufanelekileyo.Inkqubo yokwenziwa kwezi heatsinks ibandakanya amanyathelo antsonkothileyo kunye neetekhnoloji ezivumela ukuhanjiswa kobushushu okusebenzayo.Kweli nqaku, siza kuphonononga kwiinkcukacha zenkqubo yokwenziwa kweeheatsinks zeheatsinks, siphonononga amanqanaba ahlukeneyo abandakanyekayo kunye nobuchwepheshe obusetyenziswayo.

Ukuqonda inkqubo yokwenziwa kweeheatsinks, kubalulekile ukuba uqale uqonde ukuba yintoni na umbhobho wokufudumeza.Umbhobho wokufudumeza ngumbhobho wobhedu otywiniweyo okanye i-aluminiyam equlethe ulwelo oluncinci olusebenzayo, amanzi, utywala, okanye i-ammonia.Ixhomekeke kwimigaqo yokutshintsha kwesigaba kunye nesenzo se-capillary ukudlulisa ubushushu ngokufanelekileyo ukusuka kumthombo wokushisa ukuya kwi-heatsink.

Inyathelo lokuqala kwinkqubo yokwenziwa kweeheatsinks kukwenziwa kwemibhobho yokufudumala ngokwazo.Izinto ezisetyenziswayo ngokuqhelekileyo zibhedu ngenxa ye-thermal conductivity egqwesileyo.Zimbini iindlela eziphambili ezisetyenzisiweyo ukwenza imibhobho yobushushu: indlela yomxhuzulane kunye nendlela yokuntywila.

Kwindlela yomxhuzulane, umbhobho wobhedu omde, ongenanto uzaliswe ngulwelo olukhethiweyo olusebenzayo, ushiya indawo encinci ekupheleni ukuze umphunga ungene.Iziphelo zombhobho wobushushu ziyavalwa, kwaye umbhobho uyakhutshwa ukuze kususwe nawuphi na umoya okanye ukungcola.Umbhobho wobushushu uye ufudunyezwe kwelinye icala ukuphembelela ulwelo ukuba lube ngumphunga, ludale uxinzelelo ngaphakathi kumbhobho.Olu xinzelelo lubangela ukuba umphunga uqukuqelele kwisiphelo esipholileyo, apho uthi ujiye kwaye ubuyele kwindawo yokuqala ngesenzo se-capillary, uqhubekisela phambili umjikelo.Umbhobho wobushushu uye uvavanyelwe ukuvuza kunye namandla omatshini phambi kokuba udlulele kwinyathelo elilandelayo.

Indlela ye-sintering, kwelinye icala, ibandakanya ukudibanisa ubhedu okanye umgubo we-aluminium kwimilo efunwayo yombhobho wokufudumala.Lo mgubo uye ufudunyezwe de ujike kunye, wenze ulwakhiwo oluqinileyo, olunemingxuma.Emva koko, i-fluid esebenzayo yongezwa ngokuyitofa kwisakhiwo se-sintered okanye ngokuntywiliselwa kwi-heatpipe kwi-fluid ukuze ikwazi ukungena kwizinto ezixhamlayo.Okokugqibela, umbhobho wobushushu uyatywinwa, ukhutshwe, kwaye uvavanywe njengoko kukhankanyiwe kwindlela yomxhuzulane.

Emva kokuba i-heatpipes yenziwe, iqhubela phambili kwinqanaba elilandelayo lenkqubo yokuvelisa, ebandakanya ukunamathela kwii-heatsinks.I-heatsink, edla ngokwenziwa nge-aluminiyam okanye ubhedu, inoxanduva lokuchitha ubushushu obugqithiselwa yimibhobho yobushushu.Kukho iindlela ezahlukeneyo ezisetyenzisiweyo ukuncamathelisa imibhobho yobushushu kwi-heatsink, kubandakanya i-soldering, ibrazing, kunye ne-thermal adhesive bonding.

I-soldering yindlela esetyenziswa ngokuqhelekileyo ebandakanya ukufaka i-solder paste kwiindawo ezidibana nazo kwimibhobho yokufudumala kunye ne-heatsink.Imibhobho yobushushu ibekwe kwi-heatsink, kwaye ubushushu busetyenziswa ukunyibilikisa i-solder, kudala iqhina eliqinileyo phakathi kwamacandelo amabini.I-Brazing yinkqubo efanayo kunye ne-soldering kodwa isebenzisa ubushushu obuphezulu ukunyibilikisa imathiriyeli yokuzalisa eyenza iqhina phakathi kwemibhobho yobushushu kunye neheatsink.I-Thermal adhesive bonding, kwelinye icala, ibandakanya ukusebenzisa ii-adhesives ezikhethekileyo ezineempawu eziphezulu ze-thermal conductivity ukuncamathisela imibhobho yokufudumala kwi-heatsink.Le ndlela iluncedo ngakumbi xa usebenza ngeeheatsinks ezimilise nzima.

Nje ukuba iipayipi zokufudumala zifakwe ngokukhuselekileyo kwi-heatsink, indibano ivavanywa ngokusebenza kwe-thermal kunye nokunyaniseka komatshini.Olu vavanyo luqinisekisa ukuba imibhobho yokufudumala kunye ne-heatsink idlulisela ngokufanelekileyo ubushushu kwaye inokumelana neemeko zokusebenza eziya kuthotyelwa kuzo.Ukuba kukho nayiphi na imiba okanye iziphene ezifunyenwe ngexesha lokuvavanya, indibano ibuyiselwa ukuba isebenze kwakhona okanye ilahlwe, kuxhomekeke kubunzima bengxaki.

Inqanaba lokugqibela lenkqubo yokuvelisa ibandakanya ukugqiba kunye nonyango lwangaphezulu lweeheatsinks ze-heatpipe.Eli nyathelo libandakanya iinkqubo ezifana nokupolisha, i-anodizing, okanye ukugquma umphezulu we-heatsink ukomeleza amandla ayo okuphelisa ubushushu, ukuphucula ukuxhathisa kokubola, okanye ukufezekisa ubuhle.Ukukhethwa kokugqiba kunye nokuphathwa kwendawo kuxhomekeke kwiimfuno ezithile kunye nokukhethwa kwesicelo okanye umthengi.

Ukuqukumbela, inkqubo yokwenziwa kweheatsinks yinkqubo entsonkothileyo nechanekileyo ebandakanya amanyathelo abalulekileyo kunye nobuchwepheshe.Ukusuka ekwenziweni kwemibhobho yobushushu ukuyincamathisela kwiheatsink kunye nokugqiba indibano, isigaba ngasinye sidlala indima ebalulekileyo ekuqinisekiseni ukuhanjiswa kobushushu okusebenzayo kunye nokuqina kweheatsink.Njengoko izixhobo ze-elektroniki kunye neenkqubo ziqhubeka nokuvela kwaye zifuna ukusebenza kakuhle kwe-thermal, inkqubo yokwenziwa kweeheatsinks ze-heatsinks iya kuqhubeka iqhubela phambili, ithatha iindlela ezintsha kunye nezixhobo zokuhlangabezana neemfuno ezikhulayo zeshishini.
