Ngokuthuthuka kokuqoqwa kwezimoto kanye nobuhlakani, ukusetshenziswa kwamabhodi wesekethe ezimotweni kuya ngokuya kunwebeka, kusukela kuyunithi yokulawula injini kuya ohlelweni lwe-infotainment yemoto, akukwazi ukuhlukaniswa nokusekelwa kwamabhodi wesekethe. Kodwa-ke, izingxenye ze-elekthronikhi ebhodini lesifunda zizokhiqiza ukushisa lapho zisebenza, futhi uma ukuchithwa kokushisa kungalungile, ngeke kuthinte kuphela ukusebenza kwebhodi lesifunda, kodwa futhi kungabangela izingozi zokuphepha. Ngakho-ke, isisombululo sokupholisa sebhodi lesifunda sezimoto sibaluleke kakhulu. Okulandelayo kukhuluma ngokubaluleka kokuchithwa kokushisa kwamabhodi wesifunda sezimoto kanye nezixazululo ezisebenzayo zokushisa ukushisa.

一, ukubaluleka kokushisa kwebhodi lesifunda semoto:

I-1, isiqinisekiso sokusebenza: Ukushisa okufanelekile kokushisa kungaqinisekisa ukuthi izingxenye ze-elekthronikhi ebhodini lesifunda zisebenza ekushiseni okufanelekile, ukuze kuqinisekiswe ukusebenza kwayo kanye nesivinini sokuphendula.

I-2, isandiso sempilo: izinga lokushisa lingenye yezinto ezibalulekile ezithinta impilo yezingxenye ze-elekthronikhi, ukuchithwa okuhle kokushisa kungandisa impilo yesevisi yamabhodi wesifunda kanye nezingxenye.

I-3, ukuncishiswa kwamaphutha: izinga lokushisa eliphakeme kakhulu lingaholela ekuwohlokeni kokusebenza kwengxenye noma ngisho nokulimala, uhlelo lokukhipha ukushisa lunganciphisa ukwenzeka kokwehluleka okunjalo.

I-4, ukuthuthukiswa kokuphepha: ukushisa kwebhodi lesifunda kungase kubangele ukuvutha nezinye izingozi zokuphepha, ukuchithwa kokushisa okusebenzayo kuyisinyathelo esibalulekile sokuqinisekisa ukuphepha kwemoto.

二, izixazululo zokupholisa ibhodi lesekethe yezimoto:

I-1, izinto ze-substrate ze-thermal conductivity ephezulu: Khetha izinto ze-substrate ezine-conductivity ephezulu yokushisa, njenge-ceramics noma izinto ezihlanganisiwe ezisebenza kahle, ukuze uthuthukise ukusebenza kahle kokukhipha ukushisa.

2, usinki wokushisa ohlanganisiwe: Isitha sokushisa sihlanganiswe nesici sendawo eshisayo ukwandisa indawo yokukhipha ukushisa, futhi sithuthukise ukusebenza kahle kokukhipha ukushisa ngokuhambisa okungokwemvelo noma ukupholisa umoya ngempoqo.

I-3, ingcina yokuqhuba ukushisa noma i-heat conduction pad: Sebenzisa i-adhesive conduction conduction noma i-heat conduction pad njengento esibonakalayo esishisayo ukuze uthuthukise ukuqhutshwa kokushisa phakathi kwengxenye nesinki lokushisa.

I-4, ucwecwe lwethusi olushumekiwe noma ungqimba lwethusi: ebhodini lesifunda elinezingqimba eziningi lishumekwe ucwecwe lwethusi noma ungqimba lwethusi, kusetshenziswa i-thermal conductivity yensimbi yethusi ukuze kuhlakazwe ukushisa.

I-5, ukuthuthukiswa kwenqubo yokukhiqiza ye-PCB: ukusetshenziswa kwezinqubo zokukhiqiza ezithuthukisiwe ze-PCB, njengobuchwepheshe be-imaging be-laser, ukunciphisa ukumelana nokushisa nokuthuthukisa ukusebenza kokukhipha ukushisa.

I-6, ukusetshenziswa kwezinto zokushintsha isigaba (njengamapayipi okushisa) we-conductivity ephezulu ye-thermal kanye nomthamo wokumunca ukushisa ngesikhathi senqubo yokushintsha kwesigaba, ukuchithwa kokushisa okuphumelelayo.

Ukukhishwa kokushisa kwebhodi lesifunda sezimoto kuwubunjiniyela besistimu, okudingeka ukuthi kubhekwe emibonweni eminingi enqubweni yokukhiqiza. Ngokuqhubeka okuqhubekayo kobuchwepheshe be-elekthronikhi yezimoto, izixazululo zokupholisa nazo zihlala zisungula futhi zithuthuka.Ngezinyathelo eziphumelelayo zokuqothula ukushisa, azikwazi nje ukuthuthukisa ukusebenza nokuthembeka kwebhodi lesifunda, kodwa futhi zinikeze indawo yokushayela ephephile nenethezeke kakhudlwana kubashayeli kanye. abagibeli.
