Inokodzera Atlas pressure sensor P165-5183 B1203-072

Thermoelectric effect ye sensor

Semiconductor zvinhu zvine yakakwira thermoelectric kugona uye inogona kushandiswa zvinobudirira kugadzira diki thermoelectric firiji. Mufananidzo 1 unoratidza thermocouple refrigeration element inoumbwa nen-type semiconductor uye p-type semiconductor. Iyo N-mhando semiconductor uye P-mhando semiconductor yakabatanidzwa muchiuno nemahwendefa emhangura uye waya dzemhangura, uye mahwendefa emhangura newaya dzemhangura zvinongoita basa rekufambisa. Panguva iyi, kubatwa kumwe kunobva kwapisa uye kumwe kubatwa kunotonhora. Kana iyo nzira yemazuva ano yakadzoserwa shure, kutonhora uye kupisa chiito pane node inopindirana.

Kubuda kwefiriji yethermoelectric kazhinji idiki kwazvo, saka haina kukodzera kushandiswa kwakakura uye kwakakura. Nekudaro, nekuda kwekuchinjika kwayo kwakasimba, nyore uye nyore, yakanyatsokodzera kune micro-firiji munda kana nzvimbo dzinotonhora dzine zvakakosha zvinodiwa.

Iyo theoretical hwaro hwe thermoelectric firiji ndiyo thermoelectric mhedzisiro yekusimba. Kana pasina ekunze magineti, inosanganisira zvishanu zvinokonzeresa, zvinoti kupisa conduction, Joule kupisa kurasikirwa, Seebeck effect, Peltire effect uye Thomson effect.

General air conditioners nemafiriji anoshandisa fluoride chloride sefiriji, izvo zvinoita kuti ozone layer iparadzwe. Refrigerant-free refrigerators (air conditioners) naizvozvo chinhu chinokosha mukuchengetedzwa kwezvakatipoteredza. Uchishandisa thermoelectric effect ye semiconductors, firiji-isina firiji inogona kuitwa.

Iyi nzira yekugadzira magetsi inoshandura zvakananga simba rekupisa kuita simba remagetsi, uye kushanda kwayo kwekushandura kunogumira neCarnotefficiency, mutemo wechipiri we thermodynamics. Kare muna 1822, Xibe akazviwana, saka iyo thermoelectric mhedzisiro inonzi zvakare Seebeckeffect.

Haisi kungobatana chete nekupisa kwezvibatanidza zviviri, asiwo kune zvinhu zvemakonduri anoshandiswa. Kubatsira kweiyi nzira yekugadzira magetsi ndeyokuti haina zvikamu zvinotenderera zvemagetsi uye haizopfeki, saka inogona kushandiswa kwenguva yakareba. Nekudaro, kuti uwane hunyanzvi hwepamusoro, sosi yekupisa ine tembiricha yakanyanya inodiwa, uye dzimwe nguva akati wandei ezvinhu thermoelectric zvinhu zvinoputika kana kurongwa kuti zvibudirire zvakanyanya.
