Nigute ushobora guhitamo moderi yo gukonjesha ya moderi (moderi yubushyuhe)?

Beijing Huimao Cooling Equipment Co., Ltd. yashyize ahagaragara urukurikirane rwubushyuhe bwo gukonjesha amashanyarazi, moderi yubushyuhe, ibikoresho bya peltier, ibikoresho bya peltier, harimo icyiciro gisanzwe cyo gukonjesha amashanyarazi, modul ya TEC hamwe na moderi yihariye yubushyuhe, moderi ya peltier, ibintu bya peltier ukurikije ibyo abakiriya bakeneye. Hariho icyiciro kimwe cya moderi yubushyuhe, ibikoresho bya peltier, moderi ya TEC kimwe nuburyo bwinshi bwo gukonjesha amashanyarazi, moderi ya termoelektrike, imashini ikonjesha nka etape ebyiri, ibyiciro bitatu kugeza kuri bitandatu. Ubushuhe bwo gukonjesha bwa Thermoelectric (modules ya thermoelectric modules, peltier element) ikoresha ingaruka za termoelektrike ya semiconductor. Iyo umuyoboro utaziguye unyuze muri thermocouple ikorwa muguhuza ibikoresho bibiri bitandukanye bya semiconductor murukurikirane, imbeho ikonje nimpera ishyushye bikurura kandi bikarekura ubushyuhe, bigatuma bahitamo neza kubushyuhe bwo gusiganwa ku magare. Ntabwo isaba firigo iyo ari yo yose, irashobora gukora ubudahwema, nta soko ihumanya kandi nta bice bizunguruka, kandi ntishobora gutanga ingaruka zizunguruka. Mubyongeyeho, ntabwo ifite ibice byo kunyerera, ikora nta kunyeganyega cyangwa urusaku, ifite ubuzima burebure bwa serivisi kandi byoroshye kuyishyiraho. Moderi yo gukonjesha ya Thermoelectric, modul ya TEC, moderi ya peltier, moderi ya termoelektrike ikoreshwa cyane mubice byubuvuzi, ibya gisirikare na laboratoire aho bisabwa kugenzura ubushyuhe bukabije kandi bwizewe.

Nigute ushobora guhitamo ubwoko bukwiye nintangiriro yo gukoresha moderi yubushyuhe, amashanyarazi akonje, modules ya TE. Gusa muguhitamo thermoelectric gukonjesha module irashobora kugerwaho intego yo kugenzura ubushyuhe. Mbere yo guhitamo moderi ya Peltier, module ya TEC, module ya thermoelectric, birakenewe kubanza gusobanura ibisabwa byo gukonjesha, icyo intego igamije gukonjesha aricyo, ni ubuhe buryo bwo gukonjesha bwo guhitamo, ubwoko bwuburyo bwo gutwara ubushyuhe, ubushyuhe bwateganijwe, nubushobozi bushobora gutangwa. Niba uteganya guhitamo uburyo bwo gukonjesha bwa termoelektrike, module ya termoelektrike, moderi ya peltier, module ya TEC, ibintu bya peltier biva muri Beijing Huimao Cooling Equipment Co., Ltd., urashobora kumenya icyitegererezo gikenewe ukoresheje intambwe zikurikira zo guhitamo.

1. Gereranya umutwaro w'ubushyuhe

Ubushyuhe bwerekana ubushyuhe bugomba gukurwaho kugirango ubushyuhe bwintego ikonje bugere kurwego runaka munsi yubushyuhe runaka, hamwe nigice cya W (watt). Ubushyuhe bukabije burimo imitwaro ikora, imitwaro ya pasiporo, hamwe na hamwe. Ubushyuhe bukora nuburemere bwubushyuhe butangwa nintego yo gukonjesha ubwayo. Ubushyuhe bwa pasiporo nuburemere bwubushyuhe buterwa nimirasire yo hanze, convection hamwe nuyobora. Imikorere ifatika yo kubara

Igikorwa = V2 / R = VI = I2R;

Qactive = Umutwaro ushushe (W);

V = Umuvuduko ukoreshwa kuri firigo (V);

R = Kurwanya intego ya firigo;

I = Ibiriho bitembera mu ntego ikonje (A)

Ubushyuhe bukabije ni umutwaro wubushyuhe wimuriwe kubintu ukoresheje radiyo ya electronique. Inzira yo kubara:

Qrad = F es A (Tamb4 - Tc4);

Qrad = Ubushyuhe bukabije (W);

F = imiterere yimiterere (agaciro keza = 1);

e = emissivité (agaciro-urubanza agaciro = 1);

s = Stefan-Boltzmann ihoraho (5.667 X 10-8W / m ² k4);

A = Ubuso bukonje (m ²);

Tamb = Ubushyuhe bwibidukikije (K);

Tc = TEC - Ubukonje bwa nyuma bukonje (K).

Ubushyuhe bwa convective nuburemere bwubushyuhe bwimuwe mubisanzwe n'amazi anyura hejuru yikintu cyagenewe kuva hanze. Inzira yo kubara ni:

Qconv = hA (Tair - Tc);

Qconv = Ubushyuhe Bwuzuye Umutwaro (W)

h = Coefficient de transfert yubushyuhe (W / m ² ° C) (agaciro gasanzwe kindege yamazi mukirere kimwe) = 21.7 W / m ² ° C;

A = Ubuso bwubuso (m ²);

Tair = Ubushyuhe bwibidukikije (° C);

Tc = Ubushyuhe bwa nyuma bukonje (° C);

Ubushyuhe bwo gutwara ibintu nubushyuhe bwimuwe bivuye hanze binyuze mubintu bihuza hejuru yikintu cyagenewe. Inzira yo kubara ni:

Qcond = k A DT / L;

Qcond = Ubushyuhe bwimuwe (W);

k = Ubushyuhe bwubushyuhe bwibikoresho byumuriro (W / m ° C);

A = Agace kambukiranya igice cyibikoresho byumuriro (m ²);

L = Uburebure bw'inzira itwara ubushyuhe (m)

DT = Itandukaniro ryubushyuhe bwinzira yo gutwara ubushyuhe (° C) (mubisanzwe bivuga ubushyuhe bwibidukikije cyangwa ubushyuhe bwa sink ubushyuhe ukuyemo ubushyuhe bwimpera ikonje.)

Kubushyuhe bwubushyuhe bwo guhuriza hamwe no gutwara, formula yo kubara ni:

Q pasive = (A x DT) / (x / k + 1 / h);

Qpassive = Ubushyuhe (W);

A = Ubuso bwuzuye bwubuso (m2);

x = Ubunini bwurwego rwimitsi (m)

k = Gukwirakwiza ubushyuhe bwumuriro (W / m ° C);

h = Coefficient yohereza ubushyuhe (W / m ² ° C)

DT = Itandukaniro ry'ubushyuhe (° C).

2. Kubara umutwaro wose wubushyuhe

Binyuze mu ntambwe yambere, turashobora kubara ubushyuhe bwuzuye bwintego ya firigo.

Dufate ko mumushinga nyirizina, ubushyuhe bukora ni 8W, ubushyuhe bwumuriro ni 0.2W, umutwaro wubushyuhe bwa convective ni 0.8W, umutwaro wubushyuhe ni 0W, nubushyuhe bwuzuye ni 9W.

3. Sobanura ubushyuhe

Sobanura ubushyuhe bwanyuma, ubushyuhe bwanyuma nubushyuhe bwa firigo itandukanya urupapuro rwa firigo. Dufate ko mu mushinga nyirizina, ubushyuhe bw’ibidukikije ni 27 ° C, ubushyuhe bwo gukonjesha ni -8 ° C, n’ubushyuhe bwo gukonjesha DT = 35 ° C

Dufashe ko ubushyuhe bwuzuye bwintego yo gukonjesha bugereranijwe kuba 9W ukurikije igereranyo cyabanjirije iki, Qmax nziza irashobora kuboneka nka 9 / 0.25 = 36W, na Qmax ntarengwa nka 9 / 0.45 = 20. Shakisha urutonde rwibicuruzwa bya Beijing Huimao Cooling Equipment Co., Ltd kubijyanye no gukonjesha amashanyarazi, moderi ya peltier, ibikoresho bya peltier, ibikoresho bya peltier. Module ya TEC hanyuma ushakishe ibicuruzwa hamwe na Qmax iri hagati ya 20 na 36.
