Ikoreshwa rya module za peltier, module za thermoelectric mu byuma bigenzura ubushyuhe

Uburyo bwo gukonjesha bwa Thermoelectric (peltier element)—buzwi nka thermoelectric coolers (TECs)—ni ibice by'ingenzi muri sisitemu zo kugenzura ubushyuhe neza cyane. Imikorere yabyo ishingiye ku ngaruka za Peltier: iyo umuyoboro w'amashanyarazi unyuze muri thermocouple ikozwe n'ibikoresho bibiri bitandukanye bya semiconductor, ubushyuhe bunyurwa mu ihuriro rimwe (uruhande rukonje) hanyuma icyarimwe bukangwa mu ihuriro ritandukanye (uruhande rushyushye).

Mu buryo buhuriweho bwo kugenzura ubushyuhe, module za thermoelectric, module za peltier, TECs zihuzwa n'ibikoresho by'ubushyuhe bifite ubwenge (ni ukuvuga thermostats) kugira ngo bifashe kugenzura ubushyuhe mu buryo bubiri, bukora, kandi bufunze neza cyane. Hasi hari isesengura ry’amahame ngiro yazo n’ishyirwa mu bikorwa ryazo:

1. Ihame ry'ingenzi mu mikorere: Gutunganya ubushyuhe bw'icyerekezo cy'imirongo ibiri ifunze

Ifite module yo gukonjesha ya Thermoelectric, TEC ikora nk'igikoresho cyo kohereza ubushyuhe gusa kandi ntishobora kumenya ubwayo niba igomba gukonjesha cyangwa gushyushya; ubu bushobozi bwo gufata ibyemezo buri mu cyuma gipima ubushyuhe - "icyuma gitunganya ubushyuhe" cya sisitemu. Ifite sensor y'ubushyuhe ifite ubushobozi bwo hejuru, igenzura ubushyuhe nyabwo kandi ikabugereranya n'aho umukoresha agena:

• Uburyo bwo gukonjesha: Iyo ubushyuhe bwapimwe burenze aho hejuru, umugenzuzi akoresha umuyoboro utegamiye imbere, bigatuma ubushyuhe bukura neza ku ruhande rukonje.

• Uburyo bwo gushyushya: Iyo ubushyuhe bugabanutse munsi y’aho buherereye ho hasi, umugenzuzi asubiza inyuma polarity y’umuriro, bityo agahindura inshingano z’ubushyuhe bw’aho hantu habiri hagatangira gushyushya.

Ubu buryo bwo guhindura ubushyuhe butuma habaho guhindura uburyo bw'ubushyuhe mu buryo bwihuse—nta gutinda kwa mashini cyangwa gutinda k'ubushyuhe—bityo butanga igisubizo cyiza cyane ugereranije na sisitemu zisanzwe zo gukonjesha zishingiye ku bintu bitandukanye byo gushyushya kandi zigagaragaza gutinda kwa mashini.

2. Inzego zihagarariye porogaramu

Bitewe n'uko zikora buhoro, imikorere yazo idatuje, imikorere idahindagurika, ndetse n'ubushyuhe buhamye (bugera ku buziranenge bwo kugenzura bwa ± 0.1 °C, kandi bukagera kuri ± 0.01 °C mu buryo bwiza), sisitemu zo gucunga ubushyuhe zishingiye kuri Thermoelectric module (peltier cooler) TEC zikoreshwa cyane mu nzego z'ingenzi:

• Ubumenyi bw'ubuvuzi n'ubuzima: Ibikoresho bipima ubushyuhe bya Polymerase chain reaction (PCR), ibipimo by'uturemangingo tw'ikigero gikurikira, ibipimo by'ubushyuhe bya shimi, n'ibikoresho byo gutwara inkingo bikoresha ubushyuhe bwinshi—byose bisaba uburinganire bukomeye bw'ubushyuhe kugira ngo hamenyekane ubuziranenge bw'isuzuma n'umutekano w'umurwayi.

• Sisitemu z'amashusho n'amafoto: Diode za laser, sensors za optique, na infrared detectors, aho ihindagurika ry'ubushyuhe bw'iminota ritera uburebure bw'umurambararo cyangwa guhindura inzira y'amashusho; bityo rero, gushimangira TEC neza ni ingenzi kugira ngo hakomeze kuba inyangamugayo mu itumanaho rya optique no gupima ubuso bwa optique ifite ubuhanga bwo hejuru.

• Inganda n’inganda zikora ibikoresho bya semiconductor: Photolithography steppers, plasma etching tools, ADAS imaging modules, na LiDAR transceivers—aho ubushyuhe buhamye bugenga uburyo bwo gusubiramo ibikorwa, umusaruro, n’uburyo ibikoresho byizewe mu gihe kirekire mu bihe bitandukanye.

• Ibikoresho by'ikoranabuhanga n'ibikoresho byo mu rugo: Modules zo gucunga ubushyuhe za terefone zigendanwa, ibikoresho byo gukuraho ubushyuhe bikozwe mu buryo bwa "compounds", ibikoresho bikonjesha bito, n'ibikoresho byo gukonjesha uruhu—bitanga ibisubizo by'ubushyuhe bituje, bitagira firigo kandi bibungabunga ibidukikije.

3. Uduce tw'ingenzi dutuma TEC ikora neza mu bijyanye n'ubushyuhe

Kugira ngo hakoreshwe neza ubushobozi bwa module za peltier, ibikoresho bya peltier, na TEC mu buryo bwo kugenzura ubushyuhe, sisitemu nyinshi zishingiye ku zindi zigomba gutegurwa neza kandi zigahuzwa:

• Igenzura ry’ibitekerezo rishingiye kuri PID: Bitewe n’imiterere y’ubushyuhe isanzwe hamwe n’imiterere idahindagurika ya TECs, ibyuma bikonjesha bya peltier, uburyo bwa modules za peltier modules zigezweho zikoreshwa mu guhindura umuvuduko w’amashanyarazi, gukuraho amakosa ahoraho, gukumira imihindagurikire y’ubushyuhe, no gukomeza imikorere nyayo ya isothermal.

• Gucunga neza ubushyuhe bwo ku ruhande rushyushye: Kubera ko TECs zikora nk'imashini zishyushya—ntabwo ari izishyushya—gukwirakwiza neza ubushyuhe bw'imyanda buturutse ku ruhande rushyushye ni ingenzi cyane. Gucika intege kwa sisitemu akenshi bituruka ku gukonjesha guke ku ruhande rushyushye; bityo, izimashini zishyushya za aluminiyumu cyangwa umuringa zifite amashanyarazi menshi, zongereweho imikorere ishingiye ku mwuka ushyushye cyangwa imiyoboro y'amazi yo gukonjesha, ni byo bisanzwe bikorwa.

• Gupima ubushyuhe neza cyane: Gupima neza bishingiye ku byuma bipima neza nka NTC thermistors cyangwa PT100 platinum resistance thermometers. Kugira ngo ugabanye resistance y’ubushyuhe no kwemeza ko hari ibitekerezo bifatika, byuma bipima bigomba gushyirwa mu buryo bufatika mu gihe cy’ubushyuhe bugera ku buso bugenzurwa—ubusanzwe bigafatwa neza hakoreshejwe amavuta ya silicone ayobora ubushyuhe kandi bigatuzwa neza.

• Ubwirinzi bwuzuye: Utumashini dukoresha ubushyuhe bukomeye dukoresha uburyo bwo kurinda ibintu mu byiciro byinshi—harimo ubushyuhe bwinshi, ubushyuhe bwinshi, ubushyuhe bwinshi, n'uburinzi bw'amashanyarazi make—kugira ngo tugabanye ibyago bijyana n'ingaruka z'amashanyarazi ahindagurika mu gihe gito, ubushyuhe budakora neza, cyangwa imikorere idasanzwe ishobora kwangiza uburyo bwa Thermoelectric module, TEC module, TEC kuramba cyangwa umutekano wa sisitemu.

4. Isuzumabumenyi rigereranya: Ibyiza n'imbogamizi

Ibyiza:

• Kubaka ibintu bikomeye bikuraho ibice byimuka, bigatuma bikora neza, ntibikomeze kubungabungwa, kandi bigakomeza igihe kirekire;

• Uburyo bworoshye bwo gupima imiterere bushyigikira ubufatanye mu buryo buto bwo gushyiramo urubuga;

• Guhindura ikirere vuba mu bushyuhe bituma habaho gukora neza mu bushyuhe bwinshi (urugero: −50 °C kugeza +80 °C);

• Igishushanyo mbonera kidakoresha firigo gihuye n'amabwiriza mpuzamahanga agenga ibidukikije n'intego zo kubungabunga ibidukikije.

Inzitizi:

• Igipimo cy'imikorere kiri hasi cyane (COP), cyane cyane iyo ubushyuhe bukabije butandukaniye ku bushyuhe;

• Ubushobozi ntarengwa bwo gukonjesha bugengwa ahanini n'ubushobozi bwo kwanga ubushyuhe ku ruhande rushyushye;

• Ikoreshwa ry'ingufu rirushaho kwiyongera cyane mu bihe bikomeye cyane bya ΔT;

• Module za TEC zifite ingufu nyinshi (modules za thermoelectric) zisaba ikiguzi cyo hejuru cy’ibikoresho n’ibikorwa, bigira ingaruka ku bukungu bw’imikorere muri rusange.
