AVT3172B - Smoke inobvisa controller
Chero ani anoita soldering sechido chepamba anoziva kuti hazvifadzi uye panguva imwe chete zvine ngozi sei kupinza zvakananga solder fumes. Ichokwadi kuti pane zvakawanda zvakagadzirirwa-zvakagadzirirwa zvigadziriso zvefekitari zvezviputi zveutsi pamusika, asi kushandiswa kwavo kunowanzonetsa. Mhinduro yakaunzwa inokutendera kuti unyatso gadzirisa kumhanya kwe fan zvinoenderana nezvinodiwa, nekuda kwaunokwanisa kuderedza zvakanyanya ruzha rwunoburitswa neanomhanya fan.
Zvechokwadi, pfungwa yakadaro haizotsivi hood yakanaka yekupedza, uye yakanakisa uye inoshanda mhinduro ndeyekubatanidza feni ine mhepo yekufema. Zvisinei, kushandiswa kwakafanana nekushandiswa kwekabhoni sefa katuriji uye kusungirwa kugara uchifefetera mukamuri kunoderedza zvakanyanya njodzi yekufemerwa kwakananga kwehutsi hwe solder. Uye zvakare, iyo yakaratidzwa sisitimu inogona kushandiswa kazhinji - semuenzaniso, pamazuva anopisa yakakwana seyako inogadziriswa tafura fan.
Tsanangudzo yehurongwa
Iyo dhizaini yedhizaini yedunhu inoratidzwa mufig. 1. Ichi chinoshandiswa chekare cheLM317 voltage regulator. Iyo module inofanirwa kufambiswa neyakajairwa 12V plug-in magetsi akabatana kune IN socket. Diode D1 inodzivirira sisitimu kubva kumashure polarity yemagetsi ekuisa, uye capacitors C1-C4 sefa iyi voltage. Nehukoshi hwezvinhu zvakaratidzwa mudhayagiramu, iyo yekugadziridza renji inobvumidza iwe kuseta chero voltage muhuwandu kubva pa2 kusvika pa11 V painobuda, iyo inopa yakatsetseka kukurumidza kudzora kwe fan yakabatana neOUT. kubuda.
Kuiswa uye kugadzirisa
Iko kusangana kweiyo system ndeyekirasi uye haifanirwe kukonzera chero matambudziko. Ngatitangei nekutengesa zvidiki zvidiki mubhodhi, uye tipedze nekuisa heatsink neiyo U1 system uye potentiometer. Isa feni kumucheto chaiko uchishandisa hurefu hupfupi hwewaya yakakora-yakaiswa sirivheri. Mutsara wemakomba anokwira ane munda wakashama mhangura unoshandiswa nokuda kwechinangwa ichi. Nzira yekubatanidza fan inoratidzwa mumifananidzo. Iyo ndiro inochinjirwa kukwirisa 120mm mafeni uye kureba kwe38mm. Iyo yekumisikidza dhizaini ndeyekusarudza, zvichienderana nezvinodiwa uye chinangwa chekushandiswa kwechishandiso.
