Chowotcha chapaipi chophulika ndi mtundu wa zida zopulumutsira mphamvu zomwe zimatenthetseratu zinthuzo, zomwe zimayikidwa patsogolo pa zida zakuthupi kuti zizindikire kutentha kwachindunji kwazinthuzo, kuti zitha kutenthedwa pakutentha kwambiri, ndipo pomaliza pake. kukwaniritsa cholinga chopulumutsa mphamvu. Amagwiritsidwa ntchito kwambiri pakuwotcha mafuta olemera, phula, mafuta oyera ndi mafuta ena. Chotenthetsera chitoliro chimapangidwa ndi magawo awiri: thupi ndi dongosolo lowongolera. Chotenthetsera chimapangidwa ndi chitoliro chachitsulo chosapanga dzimbiri ngati manja oteteza, waya wopingasa kutentha kwambiri, crystalline magnesium oxide ufa, wopangidwa ndi compression process. Gawo lowongolera limapangidwa ndi makina apamwamba kwambiri a digito, choyambitsa chigawo chophatikizika, chiwongolero champhamvu cha reverse voltage thyristor ndi muyeso wina wosinthika wa kutentha ndi dongosolo la kutentha kosalekeza kuti zitsimikizire kuti chowotcha chamagetsi chimagwira ntchito bwino.
