Tsawg-Power Density Heating Principple of Lithium Battery Heating Tubes thiab Thermocouple Constant Temperature Control Logic
Most heating system failures and process anomalies in lithium battery production come from unreasonable power density configuration, rather than equipment aging or component damage. Ntau cov cuab yeej siv hluav taws xob ua kom pom qhov muag tsis pom qhov ntsuas kub nce ceev, siv siab - lub zog hluav taws xob cua kub cua kub uas feem ntau siv rau hauv cov xwm txheej kub ceev. Qhov siab -qhov kev siv hluav taws xob siv cua sov no ua txhaum qhov kev xav tau ntawm cov cua sov me me thiab ruaj khov ntawm cov txheej txheem lithium roj teeb, yooj yim ua rau muaj cua sov hauv zos, qhov kub ntawm qhov sib txawv loj thiab ua rau muaj kev laus zuj zus. Ua ke nrog cov kws tshaj lij thermocouple dynamic regulation logic, low -power density heating design realizes the best temperature control state for new energy battery manufacturing.
Nws yog ib qho tsim nyog kom paub qhov txawv qhov tseem ceeb ntawm lithium roj teeb txheej txheem cua sov thiab cov cua kub ib txwm muaj. Cov xwm txheej kub ib txwm muaj xws li cov khoom ziab, qhov chaw cua sov thiab dej cua sov tsom rau cov cua sov ua kom zoo, tso cai rau qhov kub thiab txias hauv cheeb tsam. Lithium roj teeb ntau lawm suav nrog cell curing, module aging thiab tiav cov khoom kom qhuav yuav tsum tau qeeb thiab zoo ib yam kub hloov, nrog rau nruj heev txwv tsis pub tus nqi ntawm kub hloov thiab lub regional kub sib txawv. Kev kub ceev ceev thiab dhau - qhov kub thiab txias yuav ua rau lub xeev ruaj khov hauv lub roj teeb, ua rau muaj peev xwm tsis sib xws, muaj zog tiv thaiv sab hauv thiab zais thermal runaway txaus ntshai ntawm cov roj teeb tiav.
Tsawg- lub zog ntom ntom tsim yog qhov tseem ceeb ntawm cov qauv ntawm cov roj teeb lithium rau cov cua kub cua sov. Sib txawv ntawm qhov siab - lub zog muaj zog cua sov cov raj uas muaj cov cua sov luv luv, cov tshuab hluav taws xob tshiab siv hluav taws xob siv hluav taws xob txuas ntxiv thiab cov qauv hluav taws xob tawg tawm. Lub zog cua sov zuag qhia tag nrho yog sib npaug sib npaug ntawm lub raj ntev lub cev, kom tsis txhob muaj cua sov hauv zos los ntawm lub zog ntau dhau ntawm ib cheeb tsam. Qhov kev tsim qauv no paub txog kev tso cua sov qeeb thiab maj mam nce siab, ua rau qhov kub thiab txias tsis tu ncua tsis tas li ntawd, thiab tswj tau qhov kub hloov pauv hauv cov txheej txheem tso cai.
According to industry operation data, low-power density heating tubes can maintain a more stable temperature field in closed lithium battery equipment compared with high-power heating elements. Txoj kev tso cua sov dispersed tshem tawm hauv cheeb tsam siab - qhov kub ntawm qhov chaw tuag, ua rau qhov kub thiab txias hauv chav laus thiab ziab qhov cub kom zoo ib yam. Qhov ntsuas kub sib npaug ua kom muaj kev sib txig sib luag thiab kev laus ntawm txhua lub roj teeb ntawm tes hauv batch ntau lawm, txhim kho cov khoom sib xws thiab kev tsim nyog tus nqi. Lub xeev cov cua sov me me kuj tsis txhob muaj kev puas tsuaj rau cov cua sov ntawm cov hlab cua sov, txuas ntxiv lub voj voog ntawm cov khoom siv hluav taws xob zoo.
Thermocouple ntse tswj logic muab tag nrho cov kev ua si rau qhov zoo ntawm tsawg-lub zog ceev cua sov tubs. Siab -rhiab heev thermocouple sensors saib tiag-lub sij hawm ambient kub hloov nyob rau hauv cov khoom siv roj teeb, pub rov qab hloov maj mam kub hloov mus rau qhov kev tswj tsis tu ncua. Qhov sib txawv ntawm qhov yooj yim ntawm -tawm kev tswj cov cua sov zoo tib yam, lithium roj teeb kub tswj cov cuab yeej siv lub zog tsis muaj zog raws li cov ntaub ntawv thermocouple. Thaum qhov kub nce mus txog qhov txheej txheem teeb tsa tus nqi, lub kaw lus cia li txo lub zog cua sov kom tswj tau micro- cua sov sib npaug, tsis txhob kub dhau los ntawm qhov siab - lub zog hluav taws xob seem.
Kev sib koom tes ua haujlwm ntawm qis- cua kub ceev thiab kev hloov kho thermocouple zoo daws qhov ntev - qhov teeb meem ntawm qhov kub thiab txias jitter hauv lithium roj teeb qhov kub thiab txias. Lub kaw lus tsis cia siab rau qhov pib thiab nres ntawm qhov siab - lub zog cua sov kom ruaj khov, tab sis tswj qhov kub thiab txias tsis tu ncua los ntawm qhov tsis tshua muaj hluav taws xob tsis tu ncua - lub zog hluav taws xob sib npaug. Lub xeev ua haujlwm no tsis tsuas yog txhim kho cov txheej txheem kub kom raug, tab sis kuj txo cov khoom siv hluav taws xob hloov pauv thiab cov cua sov lub raj qaug zog poob, paub txog ntev - lub sij hawm ruaj khov thiab lub zog - txuag cov khoom siv.
Reasonable power density configuration and professional thermocouple matching are the core keys to standardized operation of lithium battery heating systems. Customized fais fab tsim rau cov txheej txheem sib txawv ntawm cov roj teeb ntau lawm thiab cov khoom ntim tuaj yeem ua tiav qhov zoo tshaj plaws ntawm kev ua haujlwm ntawm cov cua sov, kev ruaj ntseg thiab kev nyab xeeb, muab qhov tseeb thiab txhim khu kev qha kub tswj kev txhawb nqa rau lub zog tshiab roj teeb loj.
