Ndichiri kuita basa rekuvakwa kweimba yenyika. Ini handina kusiya chishuvo chekuuya nemimwe nzira iwe kuti ushandise kuwanda polystyrene foam. Kusvika parizvino, iyi ndeimwe yemisangano inoshanda kwazvo ine huwandu hwakakura hwezvakanakira uye mutengo unodhura kwazvo. Chinhu chekutanga chandakazoona kuti zvekufamba zvigadzirwa kune hypermarket inobatsira kwazvo kuve nemudziyo-thermos umo iwe unogona kutakura zvakachengeteka chikafu chando. Kuti uwedzere kugadzirwa kwebhokisi rakadaro zvakatora zana nematanhatu nehafu yeawa yenguva yemahara. Asi ndakafunga kuenda kumberi uye ndinoshandura dhizaini kuitira kuti ishandise sefirifiriji yechokwadi.
Ngatitange kugadzira!
2. Saka ngatitangei nemudziyo wemitambo. Isu tichazoda pepa rimwe rePolystyrene foam ine zviyero zve1200x600 mm, 50 mm gobvu, stationyy banga uye roulette. Mari yemutengo wepepa rakadai mune chero chitoro chekuvaka ndeye 160 rubles. Isu tinotema mashizha pane template, tora foam inokwira uye glue mudziyo uyu.
3. Heino iyo sheet kucheka scheme. Iyo pepa ine ndege ine gobvu ye20 mm, ivo vanofanirwa kutemwa kubva kumativi ese, kunze kwezasi. Kupiswa kwemashiti anogarwa netsitsi. Tekinoroji iri nyore. Nyorera foam diki munzvimbo yegzesa, isu takamirira kweminiti 1, takamanikidza mashizha mashizha kune mumwe nemumwe uye nemaminitsi mashanu emurume kuti varege kufambisa nekuda kwehuputi. Usasiya zvisina kutongwa. Zvakaitika chete chidimbu chidiki chePolystyrene foam yakanyorwa negrey mudhara.
4 Mushure meizvozvo, bhokisi kunze rinogona kupendwa. Pendi yacho ine zvishoma colorive polystyrene foam, saka zviri nani kupenda mumatanho maviri. Iyo inokonzerwa nemidziyo inorema 820 magiramu uye ine zvisinganzwisisike zviratidzo pakupisa kurasikirwa. Mubhokisi rakadai, iwe unogona kuisa kilogiramu mashoma ezvigadzirwa zvechando uye kuti uvatakure pasina chero matambudziko mukati memaawa mashoma. Chinhu chikuru hachisi chekusanganisa zvigadzirwa nechando uye zvakadzikira zvigadzirwa. Iwe unogona kuwedzera iyo inotonhora bhatiri dhizaini.
5. Uye iwe unogona kunatsa iyo dhizaini kuti uwane firiji rakazara-rakazara. Nezvizvinangwa izvi, isu tichashandisa iyo peltier element - iyo thermoelectric transducer, iyo nheyo yekuvhiya iyo yakavakirwa pachiitiko chekusiyana kwekushisa kana magetsi aripo anoitika. Izvo zvinhu zvakadai zvinoshandiswa mufiriji yemotokari dzevarairidzi, pamwe nezvigaro zvemotokari zvine mwero.
Iyo mutengo weimwe peltier element chiitiko chakakura che60 W pane Aliexpress - 130-150 rubles. Model Tec1-12706. Mukuita kwekushanda, rimwe divi rechinhu rinopiswa, rimwe racho ratonhorera. Kune chinhu hachina kupiswa, zvinodikanwa kuti udzikise kupisa kupisa kubva kune inopisa. Kuti tiite izvi, tinoda processor inotonhorera ine radiator kubva muchitoro chekombuta, yakakosha mazana maviri nemakumi mashanu. Kuti uvandudze kutenderera kwemhepo mukati meiyo Fafigeration Chammy uye kunze kwekuratidzira kweradiator, ndakafunga kuisa vateveri pamativi ese maviri. Isu tinoshandisawo thermostat neyekunze thermal sensor uye kudzokera, kwakakosha 170 rubles, izvo zvichakubvumidza kudzora tembiricha yakatarwa mukati memudziyo. Zvakanaka, iyo waya yekuwedzera ine chinongedzo chemota fodya yezana zana.
Saka, enda kugungano.
6. Peltier element uchishandisa maPermal paste (anouya aine inotonhorera) yakaiswa pakati pevaviri maaluminium radiators. Izvo zvakakosha kutarisa pano kuti zvinokwanisika kuwedzera tembiricha yekuisa yekuisa, kana iwe ukaita gungano rezvinyorwa zvakaiswa zviviri kana zvitatu zvePeltier. Zvekuti chinhu chimwe che pelltier chakawedzera mumwe. Mune iyi embodiment, mumudziyo unonyatsotora tembiricha isina kunaka kusvika -18 degrees celsius. Kutenderedza perimeter pakati pechinhu chakarara chidimbu cheSutu insulation.
7. Pakati pavo pachavo, radiators vanobatana neyakajairwa mahwendefa ekukwirisa mwanasikana, kuvabatanidza nemapurasitiki emapurasitiki. Izvi zvinokutendera iwe kuti uongorore kutonhora uye kupisa kunopisa kubva kune mumwe nemumwe. Kuedzwa kwekutanga kuisirwa. Iyo inonyanya kukoshesa isu tichatonhora iyo inopisa side, iyo yakaderera tembiricha padanho rinotonhora. Pano vateveri vanotungamirwa kuhupfumi hwemhepo pane radiators, zvakanyatsoshanda pane kuvashandisa kuti varipurese. Mubhokisi rakavandudzwa, tembiricha ye -3 madhigirii yakawanikwa, kuAmberient tembiricha +26. Iyo foto iri pachena inooneka modhi yekutonhora, mukana wavo munharaunda yakakura yenzvimbo yekutsigira yeradiators. Uye seyakaipisisa insolised yakaramba, ini ndaishandisa chidimbu chechipfuva chekutenderera chezviputiro chinotenderera.
8. Zvino tichaita nekubatanidzwa kweiyo thermoelectric converter kuita chifukidziro chitsva chemudziyo. Kuti uwane zviri nyore kuendesa iyo yese dhizaini, isu tichawedzera ukobvu hwechifukidziro kusvika ku100 mm (2 pepa rePolystyrene foam). Mufananidzo uyu unoratidza zvakajeka gasket rakatenderedza perimeter pakati pematafura maviri.
9. Kucheka kwehunyanzvi pane yakawedzerwa polystyrene uye kubata sewangu. Namata zvakare. Mushure mekupenda, iyo yekunze yeblystyrene iri kusimba.
10. Seams ine selant, mafani ese ari maviri anotendeukira kuputika kunze. Kubva pane zvingangoita kuvandudzwa - zvinokwanisika kuderedza iyo fan kumhanyisa pane inotonhora side (iye zvino vateveri vese vanoshanda pakumhanya kwakanyanya).
11. Pedyo nedzimba, gadza iyo thermostat mubhadharo uye gadzirisa waya yemagetsi nenzira isina kubhadharwa. Kutanga isu tinodzvanya ndiro nerubatsiro rwezvakanyorwa, zvobva zvagadziridza chisunguzira.
12. mudziyo musangano. Kurema kwemudziyo pasina chifukidziro ndeye 800 magiramu, zvakanyanya sekuremerwa kwechikepe neArmelectric Converter Assembly. Mari yakazara - 1000 rubles uye kakati wandei. Miedzo ine zvigadzirwa zvemotokari zvakaratidza kugona kwehurongwa hwekuchengetedza hurongwa hwekusiya pasi (!) Yemadhigirii (ex madhigirii (ehe madhigirii (ehe, mudura rakawanda rinodziya, kunyangwe kana mhepo mamiriro) uye parizvino kushandiswa - 3 ambere. Zvinoratidzika kwandiri kuti izvi zvinokonzeresa.
Iyo inotevera mudziyo iri kuronga kuti ubve kunze kwe3 nguva dzose yakaiswa pane peltier zvinhu zvekutora firezer.
