Kachitidwe

Thermoelectric ingot ya TIG-BiTe-P/N-2 imakula ndi alloy ya Bi, Sb, Te, Se, doping yapadera komanso njira zathu zapadera zowunikira. Bi2Te3-based thermoelectric ingot imakulitsidwa mwapadera ndikupanga ma module a thermoelectric omwe amagwiritsidwa ntchito potembenuza gwero la kutentha kuyambira 100℃(373K) mpaka 350℃(623K) kukhala magetsi. Nthawi zambiri, chiwerengero cha merit ZT ya p-mtundu wathu ndi n-mtundu ingots pa kutentha osiyanasiyana 300K mpaka 600K ndi yaikulu kuposa 0.7. Module yopangidwa ndi ma ingots oterowo imatha kukwaniritsa 5% yogwira ntchito ndi 250 ℃ Delta T. Panthawiyi, ingot yathu ikuwonetsedwa ndi mphamvu zamakina abwino komanso katundu wokhazikika kwambiri, kupereka mwala wofunika kwambiri popanga ma modules odalirika opangira mphamvu.

FAQ

Kodi mungandipatseko madotolo oyenera?

Inde, ndithudi, tikhoza kupereka MSDS, COA, MOA, Certificate of Origin etc.

Kodi mumatsimikizira bwanji khalidwe lanu?

Asanaperekedwe, titha kuthandiza kukonza kuyezetsa kwa SGS, kapena kukonza zitsanzo kuti mupitirize kuwunika.

Kodi tingayendere kuofesi yanu ndi fakitale yanu?

Inde, ndithudi, makasitomala onse ochokera kunja ndi olandiridwa

Kodi mumavomereza kutumizidwa pang'ono?

Inde, njira yotumizira ndi nthawi zitha kukambirana.

Kodi mumavomereza OEM ndi ODM utumiki.

Inde, tili ndi ma lab atatu odziyimira pawokha omwe amatha kupanga kaphatikizidwe kakasitomala, kafukufuku wama mayendedwe ndi zina.

Kodi mumapereka chithandizo chaukadaulo?

Inde, ndithudi, sikuti timangofuna kupereka zinthu, komanso kuphatikizapo chithandizo chamakono, komanso zabwino pambuyo pogulitsa ntchito.
