Kev ntseeg siab ntawm COSEL hloov hluav taws xob yog feem ntau txheeb xyuas los ntawm peb yam no.
Qhov zoo ntawm cov khoom siv hluav taws xob yog kev sib xyaw ua ke ntawm kev siv tshuab thiab kev ntseeg siab. Raws li ib feem tseem ceeb ntawm lub tshuab hluav taws xob, nws txoj kev ntseeg tau txiav txim siab qhov kev ntseeg ntawm tag nrho cov system. COSEL hloov cov khoom siv hluav taws xob tau siv dav hauv ntau qhov chaw vim lawv qhov me me thiab ua haujlwm siab. Hauv daim ntawv thov, yuav ua li cas los txhim kho nws txoj kev ntseeg tau yog ib qho tseem ceeb ntawm lub zog hluav taws xob tshuab hluav taws xob. Nws txoj kev ntseeg siab feem ntau pib los ntawm peb yam no.
1. Kev ntseeg tau ntawm hluav taws xob engineering tsim thev naus laus zis ntawm kev hloov hluav taws xob
2. Electromagnetic compatibility (EMC) tsim tshuab
COSEL switching fais fab mov feem ntau siv pulse width modulation (PWM) technology. Lub pulse waveform yog duab plaub, thiab nws qhov nce thiab ntog npoo muaj ntau cov khoom sib haum xeeb. Qhov rov qab rov qab los ntawm cov zis rectifier tseem yuav tsim hluav taws xob cuam tshuam (EMI), uas yog qhov cuam tshuam tsis zoo rau kev ntseeg tau, uas ua rau electromagnetic compatibility ntawm lub system yog ib qho teeb meem tseem ceeb. Electromagnetic cuam tshuam muaj peb yam tsim nyog: cuam tshuam qhov chaw, kis nruab nrab thiab rhiab tau txais. EMC tsim yuav rhuav tshem ib qho ntawm peb cov xwm txheej no. Rau kev hloov cov khoom siv hluav taws xob, lub hom phiaj tseem ceeb yog txhawm rau txhawm rau cuam tshuam cov peev txheej, uas yog tsom rau hauv kev hloov hluav taws xob thiab cov zis hluav taws xob rectifier Circuit Court. Kev siv thev naus laus zis suav nrog kev siv tshuab lim dej, kev teeb tsa thiab kev siv thev naus laus zis, kev siv thev naus laus zis, kev siv tshuab hauv av, tshuab sealing thiab lwm yam thev naus laus zis.
3. COSEL switching fais fab mov cua sov dissipation tsim tshuab
Kev txheeb xyuas qhia tau tias thaum qhov kub thiab txias nce los ntawm 2 degree, kev ntseeg siab ntawm cov khoom siv hluav taws xob txo qis 10 zaug; lub lifespan thaum kub nce los ntawm 50 degree tsuas yog 1/6 ntawm lub neej thaum kub nce los ntawm 25 degree. Ntxiv nrog rau kev ntxhov siab ntawm hluav taws xob, qhov kub thiab txias kuj yog qhov tseem ceeb cuam tshuam rau kev ntseeg ntawm cov khoom siv. Qhov no yuav tsum muaj kev ntsuas kev ntsuas kom tsis txhob muaj qhov kub thiab txias ntawm lub chassis thiab cov khoom, uas yog thermal tsim. Lub hauv paus ntsiab lus ntawm thermal tsim yog los txo cov cua sov tsim, uas yog, xaiv txoj kev tswj kom zoo dua qub thiab cov thev naus laus zis, xws li kev hloov pauv hloov tshuab, synchronous rectification technology, thiab lwm yam; lwm qhov yog xaiv cov khoom siv hluav taws xob tsawg, txo qhov nce ntawm cov khoom siv cua sov, thiab cov xov hlau tuab ntawm qhov dav nce qhov ua tau zoo ntawm cov khoom siv hluav taws xob. Qhov thib ob yog txhawm rau txhim kho cov cua sov dissipation, uas yog, siv cov khoom siv hluav taws xob, hluav taws xob thiab cov tshuab hluav taws xob rau kev hloov hluav taws xob. Qhov no suav nrog kev tsim hluav taws xob, cua txias (natural convection thiab yuam cua txias) tsim, ua kua txias (dej, roj) tsim, thermoelectric txias tsim, cua sov yeeb nkab tsim, thiab lwm yam. Cua txias cua txias yuav dissipate ntau tshaj kaum npaug cua sov ntawm lub radiator. . Siv cov cua txias, tab sis cov kiv cua, kiv cua cov khoom siv hluav taws xob, cov khoom siv sib cuam tshuam, thiab lwm yam yuav tsum tau ntxiv, thiab cov txheej txheem cua sov yuav tsum raug xaiv raws li cov qauv tsim.
