Ngokweemfuno zokukhetha iimodyuli zokupholisa ze-thermoelectric, iimodyuli zeTEC, izinto ze-peltier

Ngokweemfuno zokukhetha iimodyuli zokupholisa ze-thermoelectric, imodyuli yeTEC, izinto ze-peltier.

Iimfuno ngokubanzi:

①, inikwe usebenziso lobushushu be-ambient Th ℃

(2) Ubushushu obuphantsi Tc ℃ bufikelelwe sisithuba esipholileyo okanye into

(3) Umthwalo we-thermal owaziwayo Q (amandla e-thermal Qp, ukuvuza kobushushu Qt) W

Ukunikezelwa kwe-Th, Tc kunye ne-Q, imfumba efunekayo kunye nenani leemfumba linokuqikelelwa ngokophawu lwemodyuli ye-thermoelectric, isixhobo se-peltier.

Njengomthombo obandayo okhethekileyo, imodyuli yokupholisa ye-thermoelectric (TE cooler) ineenzuzo ezilandelayo kunye neempawu kwisicelo sobugcisa:

I-1, Awudingi nayiphi na ifriji, inokusebenza ngokuqhubekayo, akukho mthombo wongcoliseko akukho nxalenye ejikelezayo, ayiyi kuvelisa umphumo wokujikeleza, akukho nxalenye ye-sliding isixhobo esiqinileyo, akukho vibration, ingxolo, ubomi obude, ukufakwa lula.

2,

I-5, Ukusetyenziswa okubuyela umva kweModyuli ye-Thermoelectric, iModyuli ye-Pletier, isixhobo se-Pletier ngumahluko wokuvelisa amandla obushushu, ijeneretha yamandla e-Thermoelectric, i-thermoelectric generator, imodyuli ye-TEG ifanelekile ngokubanzi ukuvelisa umbane wengingqi yobushushu obuphantsi.

I-6, amandla okupholisa okukodwa kwemodyuli yokupholisa ye-thermoelectric imodyuli ye-peltier yemodyuli ye-TE incinci kakhulu, kodwa indibaniselwano ye-thermoelectric semiconductor N, P element, kunye nohlobo olufanayo lwe-thermoeletric element series, indlela ehambelanayo idityaniswe kwinkqubo yokupholisa, amandla angenziwa makhulu kakhulu, ngoko ke amandla okupholisa anokuthi aphunyezwe kwii-watts ezimbalwa ze-milliwatt.

I-7, Uluhlu lweqondo lokushisa kwiimodyuli ze-peltier ze-thermoelectric, ukusuka kwiqondo lokushisa elichanekileyo 90 ℃ ukuya kwiqondo lokushisa elibi 130 ℃ linokuphunyezwa.

Imodyuli yokupholisa ye-thermoelectric Peltier module (imodyuli ye-Thermoelectric) ngumsebenzi wokubonelela ngombane we-DC, kufuneka ixhotyiswe ngonikezelo lwamandla oluzinikeleyo.

1, DC unikezelo lwamandla. Inzuzo yonikezelo lwamandla e-DC kukuba inokusetyenziswa ngokuthe ngqo ngaphandle kokuguqulwa, kunye nokungalunganga kukuba i-voltage kunye ne-current kufuneka isetyenziswe kwi-peltier module.peltier element, imodyuli ye-thermoelectric, kwaye ezinye zingasombululwa ngoluhlu kunye nemodyuli ehambelanayo yeemodyuli ze-TEC, izakhi ze-peltier, iimodyuli ze-thermoelectric.

2. Ac current. Olu lolona nikezelo lwamandla luqhelekileyo, ekufuneka lulungiswe kwi DC ukuze lusetyenziswe yi thermoelectric cooling modlules TEC iimodyuli, peltier modules. Ekubeni imodyuli yePletier yokupholisa imodyuli ye-thermoelectric yi-voltage ephantsi kunye nesixhobo esiphezulu sangoku, ukusetyenziswa kwe-buck yokuqala, ukulungiswa, ukuhluza, ezinye ukwenzela ukuba kube lula ukusetyenziswa komlinganiselo weqondo lokushisa, ukulawula ubushushu, ulawulo lwangoku kunye nokunye.

I-3, Ngenxa yokuba imodyuli ye-Thermoelectric yi-DC power supply, i-ripple coefficient yonikezelo lwamandla kufuneka ibe ngaphantsi kwe-10%, ngaphandle koko inempembelelo enkulu kwisiphumo sokupholisa.

I-4, I-voltage esebenzayo kunye ne-current yesixhobo se-peltier kufuneka ihlangabezane neemfuno zesixhobo esisebenzayo, umzekelo: i-12706 isixhobo, i-127 yimodyuli ye-thermoelectric izibini, i-PN ye-logarithm yesibini sombane, umda wokusebenza wombane wemodyuli ye-thermoelectric V = i-logarithm yesibini sombane × 0.11, i-06 yexabiso eliphezulu livumelekile.

I-5, Amandla ezixhobo zokupholisa ze-thermoelectric ezibandayo kunye nokutshintshana kobushushu kufuneka zibuyiselwe kwiqondo lokushisa xa zombini iziphelo (ngokubanzi kuthatha ngaphezu kwemizuzu emi-5 ukuphumeza), ngaphandle koko kulula ukubangela umonakalo kwisekethe ye-elektroniki kunye nokuqhekeka kwamacwecwe e-ceramic.

I-6, Isekethe ye-elektroniki ye-thermoelectric cooler power supply ixhaphakile.

Imodyuli yokupholisa ye-thermoelectric yenqanaba le-3: Inkcazo ye-TES3-20102T125:
