Cartridge rhaub rau hluav taws xob tsheb (EV) Daim Ntawv Thov: Cov Ntsiab Lus Tseem Ceeb

Kev lag luam hluav taws xob tsheb (EV) kev lag luam tau loj hlob sai, thiab lub tshuab ua kom sov yog qhov tseem ceeb heev rau kev ua kom paub tseeb tias EV roj teeb thiab tshuab ua haujlwm zoo thiab txhim khu kev qha. Raws li lub tsheb hluav taws xob (EVs) tau nce siab dua, qhov xav tau me me, siab -kev ua tau zoo cua sov daws tau loj tuaj. Qhov no yog vim li cas ntau EV manufacturers xaiv high voltage 800V cartridge heaters. Tab sis thaum xaiv lub tshuab rhaub kom raug rau EV daim ntawv thov, koj yuav tsum xav txog tej yam xws li chaw txwv, tswj qhov kub thiab txias, thiab kev siv hluav taws xob. Txhawm rau kom paub tseeb tias lub rhaub dej ua haujlwm nrog EV systems, koj yuav tsum paub qee yam tseem ceeb.

Hauv EVs, feem ntau yog siv lub tshuab rhaub dej kub los tswj qhov kub ntawm lub roj teeb, vim lithium - ion roj teeb yuav tsum tau khaws cia rau hauv qhov kub thiab txias (feem ntau yog 20-40 degree) kom ua haujlwm zoo thiab nyab xeeb. Thaum qhov kub thiab txias dhau lawm, nws tuaj yeem txo lub roj teeb lub peev xwm, ua kom nws lub neej luv, thiab tseem ua rau nws tsis muaj kev nyab xeeb, zoo li thaum thermal runaway tshwm sim. Cartridge rhaub tau muab tso rau hauv cov roj teeb kom sov rau hauv qee qhov chaw. Qhov no ua rau lub roj teeb ntawm qhov kub thiab txias thaum nws txias lossis thaum nws them.


Cartridge rhaub nrog lub siab voltage ntawm 800V yog qhov zoo rau cov tsheb hluav taws xob vim lawv me me thiab muaj zog heev. Vim tias cov roj teeb EV tsis muaj chav ntau, nws tseem ceeb heev uas yuav tsum muaj lub rhaub me me uas tuaj yeem muab cua sov ntau. High-voltage 800V cartridge heaters muab ntau lub zog nyob rau hauv qhov chaw me dua li tus qauv-voltage counterparts, ua rau lawv zoo meej rau haum rau hauv cov qauv roj teeb nruj. Tsis tas li ntawd, vim tias lawv muaj qhov hluav taws xob ntau dua, lawv xav tau tsawg dua tam sim no, uas txo qis lub zog poob thiab ua rau tag nrho lub cev muaj zog dua, uas yog qhov tseem ceeb rau kev nthuav dav ntawm lub tsheb fais fab.

Thaum nws los txog rau lub tshuab cua sov hauv lub tsheb hluav taws xob, ib qho tseem ceeb tshaj plaws uas yuav tsum xav txog yog qhov ntsuas kub npaum li cas. Txhawm rau kom EV roj teeb kom tsis txhob kub dhau lossis txias dhau, lawv yuav tsum tau ua kom sov sib npaug thiab tsis tu ncua. Lub tshuab rhaub dej kub nrog lub siab watt ceev (nruab nrab ntawm 5 thiab 7 W / in²) tuaj yeem ua kom sov sai thiab sib npaug, thiab qhov ntsuas kub zoo (xws li PID maub los) ua kom qhov kub nyob hauv qhov zoo. Txhawm rau muab lub sijhawm tiag tiag - tawm tswv yim thiab hloov cov khoom cua kub raws li qhov xav tau, siab -voltage 800V cartridge heaters feem ntau yog siv nrog cov ntsuas kub niaj hnub.

Lwm qhov tseem ceeb uas yuav tau xav txog yog nws yuav kav ntev npaum li cas thiab nws yuav ntseeg tau li cas. EVs tuaj yeem ua haujlwm hauv ntau qhov chaw sib txawv, los ntawm txias heev mus rau kub heev, yog li lub tshuab rhaub cartridge yuav tsum muaj peev xwm tswj tau cov xwm txheej no. Cov ntaub ntawv sheath tseem ceeb heev ntawm no. Incoloy yog ib qho kev xaiv rau EV cartridge rhaub vim tias nws tuaj yeem tswj tau qhov kub thiab txias (txog 760 degree) thiab tiv taus corrosion heev. Tsis tas li ntawd, lub tshuab cua sov yuav tsum tau muab kaw kom cov dej noo thiab av tsis tuaj yeem nkag mus, uas yuav ua rau hluav taws xob luv thiab tsis ua haujlwm. Kom paub tseeb tias lawv kav ntev, siab -voltage 800V cartridge heaters rau cov tsheb fais fab feem ntau suav nrog lub foob hermetic.

Kev siv hluav taws xob kuj tseem ceeb heev rau kev siv EV. Txhua watt uas lub tshuab rhaub dej siv lub tshuab ua kom lub tsheb luv, yog li nws tseem ceeb heev uas yuav tau xaiv lub rhaub dej kub uas ua haujlwm zoo. High voltage 800V cartridge heaters siv lub zog tsawg dua li niaj zaus vim tias lawv siv tsawg dua tam sim no, uas txhais tau tias tsawg zog poob los ntawm kev xaim. Tsis tas li ntawd, xaiv lub tshuab cua sov nrog lub watt ntom ntom kom paub tseeb tias tsuas yog siv lub zog kom zoo los ua kom sov lub roj teeb, uas yuav khaws cov khoom pov tseg kom tsawg.

Lwm qhov tseem ceeb yog kev nyab xeeb. Vim tias cov roj teeb EV siv cov khoom siv hluav taws xob siab, lub tshuab hluav taws xob yuav tsum tau ua kom tsis txhob muaj hluav taws xob tsis zoo thiab ua rau luv luv. Rau cov tsheb fais fab, siab -voltage 800V cartridge heaters muaj rwb thaiv tsev tshwj xeeb (feem ntau compacted magnesium oxide) kom tsis txhob muaj hluav taws xob tawm. Lawv kuj raug sim kom paub tseeb tias lawv ua tiav cov cai nruj nruj. Tsis tas li ntawd, lub tshuab cua sov yuav tsum muaj lub thermal fuse lossis lwm yam kev nyab xeeb uas yuav tua yog tias qhov kub thiab txias dhau lawm, uas yuav tsum tsis txhob thermal khiav.

Nws kuj tseem ceeb heev uas nws ua haujlwm nrog EV cov kev tswj xyuas cua sov. Lub tshuab rhaub cartridge yuav tsum ua haujlwm nrog lub tsheb tam sim no cov cua sov thiab cua txias kom nws siv tau yam tsis muaj teeb meem. Qee lub tsheb hluav taws xob (EVs), piv txwv li, siv lub tshuab ua kua thermal. Lub tshuab rhaub cartridge tuaj yeem muab ntxiv rau qhov system no kom sov lub coolant, uas ces ntws los ntawm lub roj teeb pob. Cov tshuab no yog tsim los ua haujlwm nrog siab -voltage 800V cartridge heaters, uas ua kom cov cua sov hloov tau sai thiab sib xws.

Thaum xaiv lub tshuab rhaub kom raug rau EV daim ntawv thov, koj yuav tsum xav txog tej yam xws li chav tsev ntau npaum li cas, qhov kub thiab txias yuav tsum tau ua li cas, nws yuav kav ntev npaum li cas, nws muaj kev nyab xeeb npaum li cas, thiab nws yuav ua haujlwm zoo li cas nrog rau qhov seem ntawm lub cev. High-voltage 800V cartridge heaters yog ib qho kev xaiv zoo rau ntau daim ntawv thov EV vim lawv me me, muaj zog, thiab siv zog tsawg. Tab sis nws yog ib qho tseem ceeb heev uas yuav tau xaiv lub rhaub nrog cov ntaub qhwv kom raug, rwb thaiv tsev, thiab watt ceev kom haum rau cov kev xav tau ntawm EV roj teeb pob. Kev txhawb nqa kev tshaj lij tuaj yeem pab EV cov neeg tsim khoom thiab cov neeg muag khoom xaiv lub tshuab rhaub dej kub zoo tshaj plaws, uas yuav ua kom nws ua haujlwm zoo thiab kav ntev.
