Mugihe nakoraga mu iyubakwa ry'inzu y'igihugu. Ntabwo naretse icyifuzo cyo kuzana ubundi buryo ushobora gukoresha kuzenguruka Polystyrene. Kugeza ubu, iyi ni imwe mumashuri meza cyane hamwe nibyiza byinshi hamwe nigiciro cyiza cyane. Ikintu cya mbere namenye ko kubicuruzwa byingendo kuri hypermarket ningirakamaro cyane kugirango ugire kontineri-thermos ushobora gutwara neza ibiryo byafunzwe. Kugirango ukore agasanduku nkiyi yatwaye amafaranga 160 nigice cyisaha yubusa. Ariko nahisemo kujya kure kandi mpitamo igishushanyo kugirango tuyikoreshe nka firigo yigenga.
Reka dutangire gukora!
2. Noneho, reka dutangire hamwe na thermos. Tuzakenera urupapuro rumwe rwibibyimba hamwe nibipimo bya mm 1200x600 mm, mm 50 z'ubugari, icyuma cya statinery na roulette. Igiciro cyurupapuro nkurwo mububiko ubwo aribwo bwose ni amafaranga 160. Twatemye ikibabi ku cyitegererezo, fata ifuro no koresha ibi bikoresho.
3. Dore gahunda yo gukata urupapuro. Urupapuro rufite indege ifite ubunini bwa mm 20, bagomba gucibwa impande zose, usibye hepfo. Gutwika impapuro birahagarikwa no kuzenguruka ifuro. Ikoranabuhanga riroroshye. Koresha ifuro nkeya ahantu hasuhuza, dutegereje umunota 1, urufunguzo rwinshi kuri buriwese hanyuma tugagenzura intoki kugirango batava mu kwaguka kw'ibifuni. Ntugende Inararibonye gusa igice gito cya polystyrene cyerekanwe nimbeba mu gishushanyo.
4. Witondere igishushanyo cyigifuniko, kimwe mumpapuro nini ziva kumuzunguruko kuva hejuru nagabanije ibice 3 kuruhande mugihe uhagaritse gukosora. Nyuma yibyo, agasanduku kari hanze karashobora gusiga irangi. Irangi rifite urusaku ruto rwa polystyrene, nibyiza rero gusiga irangi mubyiciro bibiri. Ibikoresho bivamo bifite garama 820 kandi bifite ibipimo bidasanzwe kubibazo byubushyuhe. Mu gasanduku nkaya, urashobora gushyira ibiro bike byibicuruzwa byafunzwe no kubitwara nta kibazo mu masaha make. Ikintu nyamukuru ntabwo avanga ibicuruzwa bikonje kandi bikonje. Urashobora kongeramo igishushanyo mbonera cya bateri.
5. Kandi urashobora kunonosora igishushanyo kugirango ubone firigo yuzuye. Kuri izo ntego, tuzakoresha element ya peltier - transmoelectric ya transducer, ihame ryo gukora rishingiye kubintu bishingiye ku bushyuhe mugihe hari amashanyarazi abaye. Nibintu nkibi bikoreshwa muri firigo gashinzwe umutekano, ndetse nintebe zaho zihumeka hamwe na ventilation.
Igiciro cya peltier kimwe ni ubushobozi ntarengwa bwa 60 w kuri aliexpress - amafaranga 130-150. Icyitegererezo tec1-12706. Muburyo bwo gukora, uruhande rumwe rwikintu kirashyuha, ikindi kirakonje. Kuri element ntabwo yatwitse, birakenewe gutandukanya ubushyuhe kuva kuruhande rushyushye. Kugirango dukore ibi, dukeneye gukonjesha dukonje hamwe nububiko bwa mudasobwa, bifite agaciro 250. Kunoza urujya n'uruza rw'icyumba mu Rugereko rwa finarime kandi ukuyemo kwerekana radiator, nahisemo gushiraho abafana ku mpande zombi. Dukoresha kandi thermostat hamwe na senmal yo hanze na relay, ifite agaciro kamabiri 170, bizagufasha kugenzura ubushyuhe bwibanze imbere muri kontineri. Nibyiza, kwagura insinga hamwe numuhuza w'imodoka ku mafaranga 100.
Komeza rero mu iteraniro.
6. Igihangange cya Peltier ukoresheje paste yubushyuhe (kizana cooler) zishyizwe hagati ya aluminium. Birakwiye ko tumenya hano ko bishoboka kongera ubushyuhe Gradient yo kwishyiriraho, niba ukora inteko ya poltier yashizweho 2 cyangwa 3. Kugirango umuntu ahangane peltier akonje undi. Muri iyi ndwara, muri kontineri rwose ibona ubushyuhe bubi kuri dogere -18. Hafi ya perimetero hagati yibintu bihanishwa agace k'amafuti.
7. Hagati yabo, imirasire ihuza ibyapa bisanzwe biterana kubitabo, bibahuza nimiti ya plastike. Ibi biragufasha gutandukanya uruhande rukonje kandi rushyushye hagati yabo. Kwishyiriraho urubanza. Birakabije tuzakonja uruhande rushyushye, hepfo ubushyuhe kuruhande rukonje. Hano abafana bayoborwa kuri urujya n'uruza rw'ikirere ku miribo, ntirukora neza kuruta kuyahuzaga kugira ngo bahuha. Mu gasanduku kataziguye, ubushyuhe bwa dogere -3 bwagezweho, ku bushyuhe bw'imboro +26. Ifoto igaragara neza yicyitegererezo cya congors, inyungu zabo ahantu hanini kwurubuga rushyigikiwe na radiator. Kandi nkuko ubushyuhe burya, nakoresheje igice cyamasuka yo kwishyuza imiyoboro.
8. Noneho tuzakemura kwinjizamo umuyoboro wa thermoelectric mu gifuniko gishya kuri kontineri. Kugirango byoroshye gushyira igishushanyo mbonera, tuzamura umubyimba wigifu kugeza mm (urupapuro 2 rwa polystyrene foam). Iyi foto yerekana neza gasike hafi ya perimetero hagati yimyanda ebyiri.
9. Gukata ubuhanzi kuri polystyrene no gukemura sandpaper. Ongera usenge. Nyuma yo gushushanya, igikonoshwa cyo hanze cya polystyrene kirimo gukomera.
10. Imizitiyo ifite kashe, abafana bombi bahindukirira kuvuza hanze. Kuva kunonosora - birashoboka kugabanya umuvuduko wumufana kuruhande rukonje (ubu abafana bombi bakorerwa kumuvuduko ntarengwa).
11. Hafi yinzu, shyiramo amafaranga yo gukosora hanyuma ukemure insinga yimbaraga hamwe nuburyo budahembwa. Ubwa mbere tukanda isahani dufashijwe na screw, noneho ukosore kashe.
12. Inteko ya kontineri. Uburemere bwa kontineri nta gifuniko ni garama 800, nkuko umupfundikizo uremereye inteko ya mormoelectric. Amafaranga yose - Rable 1000 hamwe nigihe gito. Ibizamini hamwe nibicuruzwa bya okisi mumodoka byerekanwe ubushobozi bwa sisitemu kugirango ukomeze ubushyuhe hepfo (!) Muri kontineri muri dogeres +29 (yego, mukiti gutondekanya) hamwe no kurya kuri ubu - 3 ampere. Kuri njye mbona ko aricyo gisubizo cyiza.
Igikoresho gikurikira kirateganya gukora ibintu 3 byashyizwemo peltier ibintu kugirango ubone firigo yuzuye.
