Kusarudza mamodule ekutonhodza ethermoelectric ane zvikamu zvakawanda (Multi-stage peltier device) kwakaoma kupfuura kusarudza mamodule ethermoelectric ane zvikamu zviviri chete, peltier cooler nekuti ine chimiro che "cascade" uye ine zvinodiwa zvepamusoro zvekutarisira kupisa uye kufananidza maparamendi emagetsi.
Danho 1: Tsanangura zvinodiwa zvikuru (mamiriro ekuisa)
Usati watarisa mamodheru chaiwo, "zviratidzo zvakaoma" zvitatu zvinotevera zvinofanirwa kutsanangurwa sezvo zvichiumba hwaro hwesarudzo:
Tembiricha yakatarwa (Tc) uye tembiricha inopisa (Th):
Kutonhora kunofanira kusvika patembiricha yakadii? (Semuenzaniso: -40°C)
Chii chinonyanya kukosha pakupisa kwechikamu chinopisa? (Chinowanzogadzirwa se25°C kana 50°C).
Verenga musiyano wetembiricha (ΔT): ΔT = Th – Tc. Machipisi ane zvikamu zvakawanda anowanzo shandiswa mumamiriro ezvinhu apo ΔT > 70°C.
Mutoro wekupisa (Qc):
Chinhu chinotonhodzwa chinoburitsa simba rakawanda sei (W)?
Kana usina chokwadi, zvakakosha kuverenga kupisa kwese kunogadzirwa nechinhu chacho, kusanganisira kupisa kwemukati, kupisa kwemhepo, uye kupisa kwemwaranzi.
Nzvimbo iripo uye magetsi anowanikwa:
Zvirambidzo zvehukuru hwekuiswa (hurefu nehupamhi)?
Ko magetsi anongogara ari voltage (se12V, 24V) here kana kuti magetsi anogara ari voltage? Ndeipi muganhu wemagetsi unogoneka?
Danho rechipiri: Nzwisisa ma parameter akakosha (zviratidzo zvepakati)
Maparamita emamodule epeltier ane nhanho dzakawanda, zvishandiso zvepletier zvine hukama hwakasimba. Tarisa pane zvina zvinotevera:
Nhamba yematanho (Matanho):
Ichi ndicho chinhu chinonyanya kusiyanisa mamodule ethermoelectric ane zvikamu zvakawanda, zvinhu zvepeltier. Kazhinji, kune matanho maviri, matanho matatu, kana kunyange matanho matanhatu ekutonhodza thermoelectric.
Mutemo wepamusoro: Kana matanho akawanda, musiyano wekupisa unogona kuwanikwa mukuru, asi kugona kutonhora (Qc) kuchava kudiki uye mutengo uchave wakakwira. Kazhinji, musiyano wekupisa wechikamu chimwe chete unenge uri pakati pe60-70°C. Kana tembiricha ye -80°C kana pasi ichidikanwa, module yepeltier yematanho akawanda inofanira kusarudzwa.
Kukwanisa kutonhora kwakanyanya (Qmax):
Zvinoreva kugona kwakanyanya kupinza kupisa kana musiyano wekupisa uri 0.
Zano rekusarudza: Kugona kutonhodza chaiko (Qc) panguva yekushanda kudiki zvikuru pane Qmax. Kazhinji zvinokurudzirwa kuti Qmax ive 1.3 kusvika 2 nguva yekupisa kwako chaiko, zvichisiya mukana wekuona kushanda zvakanaka uye hupenyu hwako.
Musiyano wepamusoro wekupisa (ΔTmax):
Zvinoreva musiyano mukuru wekupisa unogona kuwanikwa ne thermoelectric cooling module, chinhu chepeltier (kana kugona kutonhora kuri 0).
Zano rekusarudza: ΔTmax yakasarudzwa inofanira kunge yakakwira ne10-20% kupfuura musiyano chaiwo wekupisa waunoda.
Voltage uye magetsi (Vmax / Imax):
Kudzivirira kwemukati kwemodule yekutonhodza yethermoelectric ine matanho akawanda, TEC module inowanzo kuve yakakura, uye voltage inogona kunge yakakwira (senge 24V, 48V, kana kutopfuura), nepo magetsi ari madiki. Ita shuwa kuti magetsi ako anogona kuifambisa.
Danho rechitatu: Shandisa nzira yekushanda (kufananidza kwakanyatsojeka)
Iri ndiro danho rakakosha zvikuru. Usangovimba chete nehukuru hwakanyanya hwakataurwa mupepa rezvinotsanangurwa!
Mashandiro emodule yekutonhodza yethermoelectric ine nhanho dzakawanda haana kurongeka.
Sarudza nzvimbo yekushanda: Pamusiyano wekupisa kwaunoda (ΔT) uye kugona kwako kutonhora kwaunoda (Qc), tarisa girafu yecurve.
Tsvaga current yakakodzera (Iop): Tsvaga current value inoenderana.
Verenga chiyero chekushanda zvakanaka kwesimba (COP): Edza kuita kuti thermoelectric module ishande munzvimbo ine COP yakakwira (kazhinji inenge 30%-50% yemagetsi epamusoro), pane kushanda nesimba rakazara. Kushanda nesimba rakazara kunogona kukonzera kutonhora nekukurumidza, asi kunounza kupisa kwakanyanya uye hakuna kushanda zvakanaka zvakanyanya.
Danho rechina: Chimiro uye Kuiswa
Mamodule ekutonhodza ethermoelectric ane nhanho dzakawanda (multi-stage TEC module) haana kusimba kupfuura mamodule ekutonhodza ethermoelectric ane nhanho imwe chete (single stage peltier modules). Pakusarudza mhando, chimiro chemuviri chinofanira kutariswa:
Kuganhurirwa kweSaizi:
Mamodule ekutonhodza epeltier ane nhanho dzakawanda haakurudzirwi kuti aitwe akakura zvakanyanya (sekunge akakura kupfuura 62x62mm), sezvo nzvimbo yakakura kwazvo inogona kukonzera kuti maplate eceramic akotama kana kupwanyika. Pakutonhodza kukuru, zvinokurudzirwa kushandisa ma mdoules madiki akawanda akabatana zvakaenzana kana akatevedzana.
Nzira yekubatanidza:
Kubatana kweseji: Zvinokurudzirwa. Kuyerera kwemagetsi kwakafanana, kuri nyore kudzora. Kana chidimbu chimwe chete chakakuvara, chinogona kuonekwa zviri nyore (nekutyoka kwedunhu).
Kubatana kwakafanana: Hazvikurudzirwi. Kana kuramba kwemukati kwechinhu chimwe chete kukachinja, kugoverwa kwemagetsi hakuzove kwakaenzana, zvichikonzera chiitiko che "makwikwi aripo", zvichikurumidza kukuvara.
