Ana amfani da pads na thermal a cikin adaftar wutar lantarki, yana iya sa aikin adaftar wutar ya fi karko.
Nau'in adaftar wutar lantarki
Wurin da ke kan wutar lantarki inda ake buƙatar kayan aikin thermal:
1. Babban guntu na samar da wutar lantarki: babban guntu na babban wutar lantarki gabaɗaya yana da buƙatu masu girma akan ɓarkewar zafi, kamar wutar lantarki ta UPS, saboda aikin samar da wutar lantarki mai ƙarfi, babban guntu yana buƙatar ɗaukar ƙarfin aiki. na dukan na'ura, a wannan lokaci zai tara zafi da yawa, don haka muna bukatar thermal conductive abu a matsayin mai kyau thermal conduction matsakaici.
2. MOS transistor: MOS transistor shine mafi girman bangaren zafi sai dai babban guntu na samar da wutar lantarki, yana buƙatar amfani da nau'ikan kayan aikin thermal iri-iri, kamar takardar insulation ta thermal, mai mai zafi, thermal cap, da sauransu.
3. Mai jujjuyawa: Mai jujjuyawa shine kayan aikin juyawa makamashi, kafada aikin juyawa na ƙarfin lantarki, halin yanzu da juriya.Duk da haka, saboda aikin na musamman na transformer, aikace-aikace na thermal conductive kayan aiki zai kasance da buƙatu na musamman.

Amfani da kushin insulation na thermal: kulle MOS transistor da aluminium zafi nutse tare da sukurori.
Amfani da kushin zafi: Cika tazarar haƙuri tsakanin diode da na'urar dumama zafi na aluminium, da canja wurin zafin diode zuwa ma'aunin zafi na aluminium.

Thermal pad akan fil na kayan lantarki a bayan PCB.
Aiki 1: Canja wurin zafi na kayan lantarki zuwa murfin don zubar da zafi.
Aiki na 2: Rufe fil, hana zubar da murfin daga huda, kare aikin kayan lantarki.
