Qhov sib txawv ntawm ib tug tuab zaj duab xis rhaub rhaub thiab lub PTC hluav taws xob rhaub
Cov cua sov ntawm cov tsheb hluav taws xob tshiab yog qhov tseem ceeb rau roj teeb kev ua haujlwm, kev nplij siab, thiab siv zog. Tuab zaj duab xis tso cua sov thiab PTC cov cua sov yog ob lub zog tseem ceeb thev naus laus zis, thiab lawv qhov sib txawv tau yog feem ntau xav txog hauv cov hauv qab no:
1. Ua haujlwm ua haujlwm thiab cov ntaub ntawv
(1) tuab zaj duab xis rhaub: ib qho ceramic substrate (xws li alumina lossis aluminium nitride) yog siv. Tus resistor muab tshuaj txhuam (nyiaj, palladium, thiab lwm yam) yog txuas rau ntawm lub vijtsam luam ntawv thiab sintered ntawm qhov kub los tsim cov cua hauv hluav taws xob. Nws tus nqi tiv thaiv tsis ruaj khov thiab nws ua rau muaj cua sov los ntawm kev ncaj qha.
(2) PTC heater: With a positive temperature coefficient (PTC) ceramic material (such as barium titanate) as the core, the resistance increases sharply when the temperature rises, realizing the self-limiting temperature function without the need for an additional temperature control circuit.
2. Kev ua txuj ci
(1) Kev kub nyhav ua cua kub: tuab zaj duab xis ua kom sov sov inertia thiab cua kub ceev (txog 200 degree, uas haum rau cov lus teb ceev nraus; PTCS tshav kub kub qeeb qeeb thiab muaj qhov qis me ntsis.
(2) Kev Tswj Qhov Kub: Cov yeeb yaj kiab tuab yuav tsum muaj sab nraud sensors thiab tswj cov tshuab kom ua tiav qhov ntsuas kub; PTCs muaj kev nyab xeeb siab tab sis qis dua kev kho kom haum vim lawv tus kheej - txwv qhov tseem ceeb (feem ntau txwv rau 150-250 degree).
(3) ntim thiab qhov hnyav: tuab zaj duab xis ua ntais ntais thiab thinner (tuab yuav ua tau<1mm), which makes them suitable for areas with limited space; PTCs have a larger volume due to their ceramic block structure.
3. Kev ntseeg tau thiab lub neej
(1) tuab zaj duab xis hluav taws xob rhaub: kub tsis kam, lub neej muaj zog (ntev dua 100,000 lub tsheb ntev dua (ntev dua
(2) PTC heater: High stability, not easy to overheat, but long-term use may lead to reduced efficiency due to ceramic aging.
4. Tus nqi thiab daim ntawv thov kev xaiv
(1) tuab zaj duab xis rhaub: Cov txheej txheem hnyav, feem ntau siv rau cov qauv hluav taws xob siab lossis cov khoom siv hluav taws xob zoo dua lossis cov khoom siv hluav taws xob.
(2) PTC heater: low cost, mature technology, widely used in passenger compartment heating systems and mid- and low-end models.
5. Kev Siv Zog Siv Tau Sib Piv
Lub zog hluav taws xob hloov kev ua tau zoo ntawm ib qho tuab zaj duab xis kub yog> thiab nws muaj ntau dua li ntawm 85-90% ntawm PT lub zog siv zog yuav tsum tau ua haujlwm.
Ntsiab lus:Tuab zaj duab xis tso cua sov yog paub txog lawv cov peev txheej siab, lub teeb pom kev zoo, thiab lub neej ntev, thiab haum} precision thov cov xwm txheej; PTCs yog tus thawj coj los ntawm tus nqi qis thiab kev nyab xeeb siab. As new energy vehicles increase their energy efficiency requirements, the penetration rate of thick film technology has gradually expanded, but PTCs still dominate the mid- and low-end markets.
