Insimbi engenasici kwiqondo eliphezulu lobushushu bohlobo k thermocouple
Ingcaciso yeMveliso
I-Thermocouple yinto eqhelekileyo yokulinganisa ubushushu. Umgaqo we-thermocouple ulula. Iguqula ngokuthe ngqo umqondiso weqondo lokushisa ibe ngumqondiso wamandla we-thermoelectromotive kwaye uyiguqule kwiqondo lokushisa eliphakathi elilinganisiweyo ngesixhobo sombane. Nangona umgaqo ulula, umlinganiselo awulula.
UmGaqo wokuSebenza
Umbane we-thermo owenziwe yi-thermocouple uquka iinxalenye ezimbini, amandla oqhagamshelwano kunye nombane we-thermo.
Amandla oQhagamshelwano: Ii-conductor zezinto ezimbini ezahlukeneyo zinee-electron ezixinana ezahlukeneyo. Xa iziphelo ezibini zabaqhubi bezinto ezingafaniyo zidityanisiwe, ekudibaneni, ukusasazwa kwe-electron kwenzeka, kwaye izinga lokusasazwa kwe-electron lilingana noxinaniso lwee-electron ezikhululekile kunye nobushushu bomqhubi. Umahluko onokubakho uya kwenziwa kuqhagamshelwano, oko kukuthi amandla oqhagamshelwano.
Umthamo we-Thermoelectric: Xa ubushushu beziphelo zombini zomqhubi wahlukile, izinga lokusasazwa kwee-electron ezikhululekile kuzo zombini iziphelo ze-conductor yahlukile, eyintsimi ye-electrostatic phakathi kweziphelo eziphezulu kunye nezisezantsi. Ngeli xesha, umahluko ohambelanayo onokuthi uveliswe kumqhubi, obizwa ngokuba yi-thermoelectric potential. Esi sixhobo sinxulumene kuphela neempawu zomqhubi kunye nobushushu kuzo zombini iziphelo zomqhubi, kwaye akukho nto yakwenza nobude bomqhubi, ubungakanani becandelo elinqamlezayo, kunye nokusabalalisa ubushushu kunye nobude bomqhubi. umqhubi.
Isiphelo esisetyenziswe ngokuthe ngqo ukulinganisa ubushushu besixhobo sibizwa ngokuba sisiphelo sokusebenza (esaziwa ngokuba sisiphelo sokulinganisa), kwaye esinye isiphelo sibizwa ngokuba sisiphelo esibandayo (esaziwa ngokuba sisiphelo sembuyekezo); isiphelo esibandayo siqhagamshelwe kwisixhobo sokubonisa okanye isixhobo esixhasayo, kwaye isixhobo sokubonisa siya kubonisa i-thermocouple eveliswe amandla e-thermoelectric.
