Coolant Niki?

Coolant nibintu binyura muri paki yawe ya batiri ituma selile zidateka ubwazo. Ubwiza bworoshye ariko abantu benshi barabyumva nabi.

Muri porogaramu za EV na ESS turavuga kuri glycol - kuvanga amazi bizenguruka mu masahani akonje cyangwa imiyoboro ikonje ikozwe muburyo bwo gupakira. Amazi akuramo ubushyuhe muri selile, akayajyana kuri chiller cyangwa radiator, akajugunya ubushyuhe, akagaruka kubindi byinshi. Umuzingo ukomeza gukora igihe cyose ipaki ikora.

Amazi Yonyine

Wibagirwe ibyo uzi byose kuri moteri ikonjesha. Iyo Prestone yicyatsi kuva AutoZone izasenya paki ya batiri. Inhibitori ya ruswa muri antifreeze isanzwe ni ionic compound - zitwara amashanyarazi. Ukoresha ibyo ukoresheje paki ya 400V, urasaba amakosa yubutaka.

Imashini ikonjesha igomba kuba yujuje ibyangombwa bibiri antifreeze isanzwe ititaho:

Electrical resistivity above 100 kΩ·cm minimum. Most OEMs spec 150 kΩ·cm or higher. Tesla's spec calls for >200 kΩ · cm yuzuye.

Ibirimo Ion munsi ya 25 ppm. Ibice bimwe bivuga 10 ppm. Iyi niyo mpamvu udashobora gukoresha gusa amazi yatoboye no kuvanga ibyawe - glycol ubwayo igomba kuba ultra - yera.

BASF Glysantin G40 na Arteco Havoline XLC nizo ebyiri uzabona cyane mumurima. Chevron nayo ikora bateri - formulaire yihariye. Ibi bikoresha amadorari 40-60 kuri gallon na $ 12-15 kumashanyarazi ya OAT isanzwe. Birakwiye.

Kuvanga Ikigereranyo

50/50 Ethylene glycol kumazi ya deionised ni bisanzwe. Abasore bamwe biruka 60/40 mubihe bikonje. Kujya hejuru ya 60% glycol mubyukuri birababaza - viscosity irazamuka, ubushyuhe buramanuka, pompe ikora cyane.

Imibare ikonjesha:

50/50 kuvanga bikonje hafi ya dogere -37

60/40 ikugeza kuri dogere -52

Glycol yuzuye ikonja kuri dogere -12 (yego, kongeramo amazi bigabanya ingingo yo gukonjesha, chimie iratangaje)

Kubenshi muri Amerika ya ruguru 50/50 nibyiza. Niba ukoresha paki muri Minnesota cyangwa Alberta, vugana na injeniyeri wawe wumuriro kubyerekeye kugenda neza.

Igipimo cy'Uruzi

Hano niho mbona urujijo cyane. Abantu haba muburyo bunini bwo gupompa cyangwa kubitandukanya.

Kubara ntabwo bigoye. Ugomba kumenya ibintu bitatu: ubushyuhe buke paki itanga, izamuka ryubushyuhe ushobora kwihanganira kumuzunguruko, hamwe nubushyuhe bwihariye bwa coolant.

Kuri 50/50 EG / kuvanga amazi, ubushyuhe bwihariye ni 3.3 kJ / kg · K. Ubucucike hafi 1.07 kg / L.

Vuga ko ufite 75 kWh pack ikora 2C isohoka. Nibyo bisohoka 150 kwat. Igishushanyo 5 - 6% kubyara ubushyuhe kuri kiriya gipimo - kubyita 8 kilowat yumuriro. Niba ushaka kubika inlet - kugeza kuri delta munsi ya dogere 4:

8000 W ÷ (1.07 kg / L × 3300 J / kg · K × 4 K) × 60=34 L / min

Numubare nyawo uva kumushinga nyawo. Pompe nyirizina twakekaga ko yapimwe 40 L / min kugirango iduhe icyumba cyumutwe.

Amapaki menshi yabagenzi atwara 8-15 L / min mumitwaro isanzwe yo gutwara. Ibibyimba mugihe cyo kwishyuza byihuse cyangwa imbaraga zihamye.

Ibitagenda neza

Reba uburyo buke bwo gutsindwa mumyaka.

Ubwoko bwa coolant butari bwo.Gura hejuru hamwe na antifreeze isanzwe mugihe cya serivisi. Umuyoboro. BMS ibona amakosa yo kwigunga, ipaki irahagarara. Niba ufite amahirwe biratera kode gusa. Niba udafite amahirwe ubona arcing imbere.

Kwanduza.Amazi meza. Urubuga rumwe nakoraga rwakoresheje amazi ya robine kugirango yuzuze bwa mbere kuko "uko byagenda kose. Usibye ko barenze deionizer. Ibirimo bya Chloride byari 180 ppm. Byabaye ngombwa koza sisitemu yose hanyuma ugasimbuza amasahani akonje - $ 40k akazi kumurimo wa 200k.

Gutesha agaciro igihe.Glycol oxyde. Ikora aside ya glycolike, hanyuma aside aside. pH ibitonyanga. Inhibitori ya ruswa ikoreshwa. OEMs ivuga 4 - 5 yumwanya wa serivisi ariko nabonye coolant igenda nabi mumyaka 2 mubidukikije-temp. Ikizamini buri mwaka.

Umwuka muri sisitemu.Kuva amaraso ya EV gukonjesha biroroshye. Umufuka wo mu kirere utera ahantu hashyushye. Akazu kari munsi yigituba gikora dogere 8-10 kurenza abaturanyi. Kwihuta gusaza, ubushobozi burashira, amaherezo gusaba garanti.

Kugerageza Imiterere ya Coolant

Ukeneye ibipimo bitatu:

pH - gukonjesha gushya gukora 7.8 kugeza 8.5 bitewe na formulaire. Munsi ya 7.0 bisobanura paketi ya inhibitor yabuze. Hindura.

Kurwanya - metero zigendanwa zirahari ariko zihenze. Ohereza icyitegererezo muri laboratoire niba udafite. Ikintu cyose kiri munsi ya 50 kΩ · cm kigenda kigabanuka.

Glycol yibanze - refractometer ikora. $ 30 igikoresho, gifata amasegonda 10. Urimo kugenzura niba biva muri kondegene cyangwa umuntu wongeyeho amazi meza.

Amato amwe akora gahunda yo gusesengura amavuta, kohereza ingero muri Polaris Labs cyangwa Blackstone buri mezi 6. Kurenza urugero kuri porogaramu nyinshi ariko birumvikana kubyubaka binini.

Immersion Direct vs Cooling itaziguye

Ibintu byose byavuzwe haruguru bifata ubukonje butaziguye - amazi anyura mumiyoboro, ntabwo akora kuri selile. Nibyo 95% byibiri hanze aha.

Kwibizwa mu buryo butaziguye biratandukanye. Ingirabuzimafatizo zicaye mu bwogero bwamazi ya dielectric. Nta byapa bikonje, nta bikoresho byubushyuhe, ibikoresho byamazi bishobora guhita. Kwimura ubushyuhe nibyiza. Ingorabahizi ziri hasi muburyo bumwe, hejuru mubindi.

Amazi aratandukanye nayo . 3 M Novec na Solvay Galden nizina rinini. Ibi nibintu bya florine, ibintu bike cyane, bitangiza imiti. Kandi bihenze cyane - $ 300-400 kuri litiro kubintu bimwe.

Kwibiza mu buryo butaziguye birerekanwa mububiko bwa grid hamwe na - yimikorere yimodoka. Ntabwo arimbere ariko imikorere yubushyuhe iragoye kubijyaho impaka.

Urupapuro rwihariye

Byihuse kubyo ugomba kureba mugihe utanga amashanyarazi akonje:

Shakisha MSDS n'impapuro za tekiniki kubaguzi bawe. Niba badashobora gutanga amakuru yo kurwanya, shakisha undi mutanga.
