IPhepha lokuQinisekisa ngokweSiko-iPhepha leSikhenkcisi seSemiconductor

Inkcazelo emfutshane:

Umgaqo osebenzayo wephepha lefriji le-semiconductor lisekelwe kumgaqo kaPeltier.Esi siphumo safunyanwa okokuqala nguJac Peltier ngo-1834, oko kukuthi, xa isekethe yenziwe ngabaqhubi ababini abahlukeneyo A kunye no-B badityaniswe nomsinga othe ngqo, obunye ubushushu buya kukhutshwa kwindawo ekudityaniswa kuyo ukongeza kubushushu beJoule, ngelixa elinye ijoyinti. ifunxa ubushushu, Ngaphezu koko, le nto ibangelwa yi-Peltier effect iyabuyiswa.Xa utshintsha indlela yangoku, i-exothermic kunye ne-endothermic joints nayo iyatshintsha.Ubushushu obufunxayo kunye nokukhutshwayo buhambelana ngokuthe ngqo nobukhulu bangoku I [a], kwaye inxulumene neempawu zabaqhubi ababini kunye nobushushu besiphelo esishushu.

*Iinzuzo zethu


Ukuxhomekeka kwiqela lobuchwephesha kunye nelabhoratri e-Shenzhen, sibonelela ngezona zisombululo zokusetyenziswa kwemodyuli ye-thermoelectric.Isiqwenga ngasinye semodyuli yethu sivavanywa amaxesha ama-3 phantsi kwezixhobo eziphambili.Umlinganiselo wokwaliwa kweemodyuli zethu ungaphantsi kwesihlanu kwiwaka.Iimveliso zethu zisetyenziswa ngokubanzi kwizixhobo zonyango, unxibelelwano lwe-optical, i-aerospace, izithuthi njl.Ngoko iimfuno zakho zinokwaneliswa ngokufanelekileyo.

*Indlela yokugweba umgangatho we-chip yefriji ye-semiconductor


Umgangatho we-chip yefriji ye-semiconductor unokugwetywa ngokulinganisa ukuchasana kwayo, okwangoku okanye i-voltage nge-multimeter.Uluhlu oluqhelekileyo lokumelana ne-semiconductor yefriji ye-chip yi-0-0.05 Ω, uluhlu oluqhelekileyo lwangoku lwe-Hangzhou semiconductor yefriji ye-chip yi-0-0.09 a, kunye noluhlu oluqhelekileyo lwe-voltage ye-semiconductor yefriji ye-chip yi-0-0.1 v.
Iphepha lefriji ye-semiconductor
1. Okokuqala, qhagamshela iingcingo ezimbini zovavanyo lwepeni yendalo yonke kwiphepha le-antifreeze le-semiconductor kunye nocingo olusezantsi, kwaye uhlukanise ucingo olubomvu kwintambo emnyama.Umgca obomvu yi-electrode eqinisekileyo ye-chip ye-semiconductor enomkhenkce, kwaye umgca omnyama yi-electrode engalunganga ye-chip ye-semiconductor enomkhenkce.
2. Emva koko, thatha isigqibo sokuba ulinganise i-AC okanye i-DC ye-semiconductor freezing sheet ukujonga umgangatho.Kwi-voltage ye-DC, lungisa igiya kwindawo ye-DC njengoko kubonisiwe kwaye uyidibanise kumgca wokulinganisa.
3. Ukuba umgca ngu-220V, umgca omnyama uya kusetyenziswa.Xa ulinganisa i-AC yangoku ye-chip yefriji ye-semiconductor, i-gear kufuneka ilungiswe kwindawo ye-AC.I-DC kunye ne-AC zihambelana neegiya ezimbini ezahlukeneyo ngokulandelelana.
4. Faka imigca yovavanyo ebomvu nemnyama kumahluko womgca.Ixabiso elifundwa yi-multimeter yi-00.4a.Kukho umboniso wedijithali, inani langoku leesekethe eziqhelekileyo zePeltier, ezibonisa ukuba iPeltier ilungile.
