Ulwakhiwo lwayo olulula, iindleko eziphantsi, kunye nokugcinwa kwayo okulula kuyenza ifaneleke kakhulu kwiimeko ezininzi zoshishino.
1. Yintoni iMacro-Channel Cooling?
Ukupholisa imijelo emikhulu kubandakanya ukusetyenziswa kwemijelo emikhulu yokuhamba kwe-coolant (ngesiqhelo kuluhlu lweemilimitha) eyakhelwe kwiipleyiti zokupholisa okanye iimodyuli. Ezi mijelo zikhokela ulwelo lwe-coolant—oluqhele ukuba ngamanzi angena-ion, izisombululo ezisekelwe kwi-glycol, okanye ezinye izinto zokupholisa zoshishino—ngenkqubo ukuze kususwe ubushushu obuveliswa ngexesha lokusebenza kwesixhobo. Xa zidityaniswe ne-loop yokupholisa amanzi, olu seto lwenza ulawulo lobushushu oluqhubekayo nolusebenzayo.
