Thermally conductive ingcina: izici futhi izicelo glue

Thermally ingcina conductive livame ukusetshenziswa ukulungisa heatsink kuya processor noma inkumbulo, LED yehhashi egibele, kanye nezinye izingxenye ku kurediyetha, ezimweni lapho ukusetshenziswa unama ezishisayo kanye zalapho okungalungile noma kungenzeki nhlobo.

umkhiqizo incazelo

Ngaphandle, le ezishisayo conductivity ingcina libukeka mass viscous ingcina-like white ukungaguquguquki iyunifomu kuyinto cishe ayinaphunga. It okuthengiswa tube noplastiki cap isikulufa, okuyinto evimbela umoya angangeni tube futhi ivumela ukugcina ingcina ewuketshezi. Lapho uqala ukusebenzisa kubalulekile ibhoboze enamathela ekhethekile zokuzivikela ku udebe tube. Lapho usebenzise cap is unscrewed kalula, batfole glue.

Clay isetshenziswa ukuxhuma izingxenye ngokushesha sishisiswe thermally conductive ukushisa echibini.

Izinzuzo ingcina

Amandla kanye kwabantu uma sezomile kakhulu, eyakho izimfanelo ezinhle emimoya a ingcina thermally conductive "Alsil". adhesion letitsite ingcina kuya ebusweni ihlinzeka uxhumano oluphephile.

Thermally glue conductive "osabalalayo" okuthengiswa uphawu emaphaketheni moya evikela kusuka iphele ukuphuma phezu isikhathi eside. emaphaketheni ucingo ngale ndlela kwandisa ukuphila eshalofini we ingcina. Kuyinto elula kakhulu, ngoba akudingekile isikhathi ngasinye ukuthenga ngamapayipi entsha futhi ayizange isetshenziswe kuze kube sekupheleni elidala. Lena inzuzo elingenakuphikwa "Radian" ngokuziqhathanisa izimpahla ezivezwa nezinye abakhiqizi.

On the izici kokokunamathisela thermally conductive kufana "Alsilom".

Ukuze ususe ingxenye enamathiselwe kurediyetha esebenzisa i-glue, sebenzisa ummese: ungamumbi ngokucophelela nto ezidingekayo bese uyalikhipha, abese ulungiswe noma esikhundleni.

Thermally ingcina conductive ngoba radiators umise ngokwaso njengoba ithuluzi okuthembekile futhi enza izinto ezihlukahlukene ukuze ukufakwa ngisho diodes enamandla kakhulu ukukhanya-likhipha nezinye izingxenye.

Indlela yokufaka isicelo glue thermally conductive?

Umhlangano inqubo diode nesikimu ingcina siqukethe izinyathelo eziningana:

1. Degrease zonke evele ngalo une ukusebenza ngokusebenzisa utshwala noma acetone.
2. Sebenzisa i-glue conductivity ezishisayo e esincane ungene ebusweni izingxenye selehlile.
3. Yenza umzamo push kobuso ingxenye selehlile bese uyazama prodelyvat ezinyakazayo Translational isiyingi ngokulinganayo ukusabalalisa ingcina phezu bonke ubuso izingxenye selehlile ku kurediyetha.
4. Vikela snuggling for 3-4 imizuzu for adhesion kangcono.
5. Ake ingxube eyomile. Isinamathiseli Uqinisa ngemva kwemizuzu engu-20, kodwa omiswe ephelele kwenzeka ngosuku kuphela ngokusebenzisa.

Hotmelt ngezandla zabo?

Dala ingcina, ukushisa conductive, ungakwazi ngumnikazi ngisho. Kulesi sihloko uzothola amathiphu ezilula kodwa eziphumelelayo sendlela ukwenza ingcina thermally conductive ngezandla, ngaphandle uma ungenalo izindlela. Ngakho, lokho kufanelekile ukulungisa izingxenye ukuba kurediyetha, ngesikhathi esifanayo ngaphandle kokuyekethisa uhlelo (kubalulekile ukuthi conductivity ezishisayo sasisekelwa)?

Ukuze uthole ephezulu amandla thermally ingcina conductive, kubalulekile ukuxhuma 25 ml glycerol futhi 100 g oxide phambili. Amanzi aphuma glycerol ayahwamuka ngokubeka amalahle ingxube lokushisa 200 Celsius. oxide phambili powder uyabaselwa kakhulu imizuzu embalwa, ngesikhathi esifanayo ulondoloze isimo izinga lokushisa at degrees 300 Celsius. kokuchitha nje zokukhwabanisa enjalo, yezingxenye axutshwa. Imiphumela iba yinhlanganisela yokukhandleka nokunamathisela kuyinhlama, ezakhiwe yokusabela chemical okuyinto.

Enye indlela elula unamathisele diodes kuya heatsink - epoxy okuxubile nokunamathisela ezishisayo. Kodwa kukhona izimo lapho ukusetshenziswa unama ezishisayo okungalungile, khona-ke kungcono ukusebenzisa hotmelt walungisa ngokukhethekile noma ngithenge.
