Kutheni le nto ukutshatyalaliswa kobushushu be-mg4 ev yifeni endaweni yokupholisa kwamanzi?
Kwiinkqubo ze-automotive electronic systems, ulawulo lobushushu belusoloko lungumceli mngeni, lufuna ngokubanzi ukuba inkqubo isebenze ngokuqhelekileyo phantsi kobushushu be-ambient ye -40 ° C ~ + 65 ° C. Ubushushu be-ambient ngaphakathi kwindlu buya kuba nokunyuka kobushushu obumalunga ne-20°C, ngoko ke ubushushu obuphezulu be-ambient efunwa yibhodi ye-PCB ngokwenene ukumelana buya kuba phezulu ukuya kuma + 85°C.
Emva koko, kugxininise ngakumbi kwindawo yendawo, efana nokubonelela ngombane, i-CPU kunye nezinye iimodyuli ziya kuba kukusetyenziswa kobushushu, kwaye ziqhubele phambili ubushushu be-ambient kwi-chassis, kwaye imeko enzima iye yasondela kumda wokushisa wee-chips ezininzi. Ngoko ke, kwinqanaba lokuqala loyilo lwenkqubo, kuyimfuneko ukucwangcisa isicwangciso soLawulo lwe-Thermal kunye noyilo lwamanyathelo ahambelanayo.
Ngokwentelekiso ilula kwaye irhabaxa, kodwa umlinganiselo osebenzayo wokuphelisa ubushushu kukongeza ifeni yokuchitha ubushushu, ewe, oku kuya kwandisa ixabiso loyilo kunye nengxolo yomatshini. Ke ngoko, iimfuno zethu kuyilo lweesekethe zabalandeli zikwasekwe kwezi ndawo zimbini zokuqala:
1), isiphaluka kufuneka sibe lula, iindleko eziphantsi;
2), isantya somqhubi silingana nengxolo, ngoko ke isantya somqhubi siyafuneka ukuba silinganiswe kwaye silawuleke. Inkqubo iya kulungelelanisa isantya se-fan ngokweqondo lobushushu le-ambient, ngokukhethekileyo ukulawulwa kwesantya esingenanyathelo, kwaye sizame ukulungelelanisa ukusebenza kakuhle kobushushu kunye nengxolo.
Ukusetyenziswa kokupholisa kwamanzi kulula ukonakalisa kwaye kufuna ukutshintshwa rhoqo kunye nokugcinwa, kwaye imoto ihlala inamaqhuma, angafanelekanga ukusetyenziswa kweenkqubo zokupholisa amanzi.
