Pamapangidwe ozungulira, kutentha komwe kumapangidwa ndi coil inductance kumagwira ntchito yofunika kwambiri pozungulira. Kutentha kopangidwa kumapangitsa kuti kutentha kwa coil inductive kukwera. Kutentha kumakhudza kwambiri koyilo ya inductive. Kukaniza kwa koyilo nthawi zambiri kumawonjezeka ndi kutentha. Kodi tingachepetse bwanji kutentha kopangidwa ndi koyilo yolowera pa koyilo? Tsopano chonde onani chidule cha nkhaniyi.

Njira zotsatirazi zimagwiritsidwa ntchito pochepetsa kukhudzidwa kwa kutentha kwa coil inductance padera.

1. Chigawo chilichonse chamagetsi m'dera lililonse chimakhala ndi mpweya wotentha, ndipo mtengo wa mpweya wotentha umatha kuwonetsa mphamvu ya kutentha kwapakati kapena pakati pa ma mediums. Kukula kwa impedance yotentha kumasiyanasiyana ndi zida, malo akunja, kugwiritsa ntchito ndi malo oyika. Kugwiritsa ntchito zida zamagetsi zamagetsi zomwe zimakhala ndi matenthedwe apamwamba kwambiri ndi njira yachikhalidwe komanso yothandiza kwambiri yochepetsera kutentha kwa ma inductance coils.

2.Kwa kutentha kwa kutentha ndi dera, kuzizira kozizira kumagwiritsidwa ntchito kwambiri pamsika pakali pano. Mwa kusintha mpweya wotentha kuzungulira koyilo ya inductance, mpweya wozizira wokakamiza umagwiritsidwa ntchito m'malo mwa mpweya wotentha, ndipo kutentha kwa dera kumaperekedwa mosalekeza kumlengalenga wozungulira. Nthawi zambiri, chotenthetsera chozizira chimatha kupititsa patsogolo mphamvu ya kutentha ndi 30%, koma choyipa ndichakuti chimatulutsa kugwedezeka ndi phokoso. Zimangogwiritsidwa ntchito pazida zamakono kapena zamakono monga makompyuta, zipangizo zamagalimoto, zosinthira pafupipafupi, zida za hardware, zipangizo za firiji, ndi zina zambiri.

3.Kuphimba kutentha kumagwiritsidwa ntchito mwachindunji pamwamba pa chinthucho (inductance coil) kuti chizizirike, ndipo kutentha komwe kumatenthedwa kumatuluka ndi kutayika kumalo akunja pamene kutentha kumasonkhanitsidwa ndi kutenthedwa. Itha kuwonjezeranso kudziyeretsa, kutsekereza, kukana dzimbiri, kutsimikizira chinyezi ndi zinthu zina. Ndi njira yatsopano yochepetsera kukhudzidwa kwa kutentha kwa coil inductance pa dera.

4.Thermal conductivity ndi kutentha kusungunuka kwamadzimadzi ndi zazikulu kuposa za gasi, kotero kuziziritsa kwamadzi kumakhala bwino kuposa kuzizira kwa fan. Choziziriracho chimalumikizana mwachindunji komanso mosagwirizana ndi koyilo yolowetsa mphamvu kapena zida zina zamagetsi kuti zitenthe kutentha ndikutulutsa kutentha kunja kwa dera. Zoyipa zake ndizokwera mtengo, kuchuluka kwakukulu ndi kulemera kwake, komanso kukonza zovuta.

5.Heat conductive adhesive and heat dissipaste phala ali ndi ntchito yofanana ndi tanthauzo lenileni. Amakhala ndi ma conductivity abwino kwambiri a kutentha ndipo amatha kupititsa patsogolo mphamvu ya kutentha kwazinthu zamagetsi muderali. Nthawi zambiri amagwiritsidwa ntchito kupaka pamwamba pazigawo zamagetsi (ma coil inductive) kuti apereke kutentha kwa radiator (radiator imapangidwa ndi mkuwa kapena aluminiyamu). Rediyeta imatenga kutentha ndikuwunikira kunja kwa dera, kusunga kutentha kwa dera kukhala koyenera. Kachiwiri, phala lotenthetsera kutentha lili ndi umboni wina wa chinyezi, fumbi, anti-corrosion ndi ntchito zina, ndipo ndi njira yabwino yopititsira patsogolo kutentha kwa kutentha ndi kukhazikika kwa zipangizo zamagetsi.
