Kodi Chotenthetsera Chimagwira Ntchito Motani?
Kodi munayamba mwadzifunsapo momwe chotenthetsera chanu chamagetsi, chowotcha, kapena chowumitsira tsitsi chimatulutsa kutentha? Yankho lagona pa chipangizo chotchedwa heat element, chomwe chimasintha mphamvu ya magetsi kukhala kutentha kudzera mu kukana. Mu positi iyi yabulogu, tifotokoza za chinthu chotenthetsera, momwe chimagwirira ntchito, ndi mitundu yotani yazinthu zotenthetsera zomwe zilipo. Tidzakudziwitsaninso za Beeco Electronics, m'modzi mwa opanga zinthu zotenthetsera ku India, yemwe angakupatseni zida zotenthetsera zapamwamba komanso zotsika mtengo pazogwiritsa ntchito zosiyanasiyana.
Kodi chotenthetsera ndi chiyani?
Chotenthetsera ndi chipangizo chomwe chimatulutsa kutentha pamene mphamvu yamagetsi idutsamo. Kawirikawiri amapangidwa ndi koyilo, riboni, kapena chingwe cha waya chomwe chimakhala ndi kukana kwakukulu, kutanthauza kuti chimatsutsana ndi kutuluka kwa magetsi ndipo chimatulutsa kutentha chifukwa chake. Chodabwitsachi chimadziwika kuti Joule Heating kapena Resissive Heating ndipo ndi mfundo yomweyi yomwe imapangitsa kuti bulb iwala. Kuchuluka kwa kutentha komwe kumapangidwa ndi chinthu chotenthetsera kumadalira mphamvu yamagetsi, panopa, ndi kukana kwa chinthucho, komanso zinthu ndi mawonekedwe a chinthucho.
Kodi chotenthetsera chimagwira ntchito bwanji?
Chinthu chotenthetsera chimagwira ntchito potembenuza mphamvu yamagetsi kukhala kutentha kupyolera mu kukana. Mphamvu yamagetsi ikadutsa mu chinthucho, imakumana ndi kukana, zomwe zimapangitsa kuti mphamvu zina zamagetsi zisinthe kukhala kutentha. Kutentha kumatuluka kuchokera kumbali zonse, kutenthetsa mpweya wozungulira kapena zinthu. Kutentha kwa chinthucho kumadalira momwe kutentha kumapangidwira ndi kutentha komwe kumatayika ku chilengedwe. Ngati kutentha kwapangidwa ndi kwakukulu kuposa kutentha komwe kunatayika, chinthucho chidzatentha, ndipo mosiyana.
Kodi mitundu yosiyanasiyana ya zinthu zotenthetsera ndi iti?
Pali mitundu yosiyanasiyana ya zinthu zotenthetsera, kutengera zinthu, mawonekedwe, ndi ntchito ya chinthucho. Zina mwa mitundu yodziwika bwino ya zinthu zotenthetsera ndi izi:
Zinthu zotenthetsera zachitsulo: Izi ndi zinthu zotenthetsera zopangidwa ndi mawaya achitsulo kapena nthiti, monga nichrome, kanthal, kapena cupronickel. Amagwiritsidwa ntchito pazida zotenthetsera wamba monga ma heater, toaster, zowumitsa tsitsi, ng'anjo, ndi uvuni. Amakhala ndi kukana kwakukulu ndipo amapanga gawo loteteza la okusayidi likatenthedwa, kuletsa kuwonjezereka kwa okosijeni ndi dzimbiri.
Zinthu zotenthetsera zozikika: Izi ndi zinthu zotenthetsera zopangidwa ndi zitsulo zachitsulo, monga mkuwa kapena aluminiyamu, zomwe zimakhazikika mwanjira inayake. Amagwiritsidwa ntchito pakuwotcha mwatsatanetsatane monga zowunikira zamankhwala ndi zakuthambo. Amakhala ndi kukana kochepa ndipo amatha kupereka kutentha kofanana komanso kosasinthasintha.
Ceramic and semiconductor heat elements: Izi ndi zinthu zotentha zopangidwa ndi ceramic kapena semiconductor materials, monga molybdenum disilicide, silicon carbide, kapena silicon nitride. Amagwiritsidwa ntchito potenthetsera kutentha kwambiri monga mafakitale agalasi, sintering ya ceramic, ndi mapulagi a injini ya dizilo. Amakhala ndi kukana pang'ono ndipo amatha kupirira dzimbiri, makutidwe ndi okosijeni, komanso kugwedezeka kwamafuta.
Zinthu zotenthetsera za PTC Ceramic: Izi ndi zinthu zotenthetsera zopangidwa ndi zida za ceramic zomwe zimakhala ndi kutentha kwabwino kwa kukana, kutanthauza kuti kukana kwawo kumawonjezeka ndi kutentha. Amagwiritsidwa ntchito poziwotcha pawokha monga zotenthetsera mipando yamagalimoto, zowongola tsitsi, ndi opanga khofi. Amakhala ndi kukana kosagwirizana ndipo amatha kupereka chitetezo ndi mphamvu zamagetsi.
