Kupititsa patsogolo
Kuwongolera kwa chinthu choyendetsa kutentha chopindika
Yunivesite ya Shanghai ya uinjiniya ndi ukadaulo yapanga mtundu watsopano wa thermostat yochokera ku thermostat ya paraffin ndi cylindrical coil spring coil based copper shape memory alloy ngati chinthu choyendetsa kutentha. Pamene kutentha kwa silinda yoyambira ya thermostat kuli kochepa, kasupe wa bias amakanikiza kasupe wa alloy kuti atseke valavu yayikulu ndikutsegula valavu yothandizira kuti iyende pang'ono. Pamene kutentha kwa coolant kukukwera kufika pamtengo winawake, kasupe wa memory alloy amakula ndikukanikiza kasupe wa bias kuti atsegule valavu yayikulu ya thermostat. Pamene kutentha kwa coolant kukukwera, kutseguka kwa valavu yayikulu kumawonjezeka pang'onopang'ono, ndipo valavu yothandizira imatseka pang'onopang'ono kuti iyende bwino.
Monga gawo lowongolera kutentha, chosungiramo zinthu zokumbukira chimapangitsa kuti kutsegula kwa valavu kukhale kofatsa kwambiri ndi kusintha kwa kutentha, zomwe zimathandiza kuchepetsa mphamvu ya kutentha pa silinda yotchinga yomwe imayambitsidwa ndi madzi ozizira otsika kutentha mu thanki yamadzi pamene injini yoyaka mkati ikuyatsidwa, ndikukweza moyo wa ntchito ya thermostat. Komabe, thermostat imasinthidwa kuchokera ku thermostat ya sera, ndipo kapangidwe kake ka chinthu chowongolera kutentha kali ndi malire pamlingo winawake.
Kukonza valavu yopindika
Thermostat imakhudza kwambiri choziziritsira. Kutayika kwa mphamvu kwa injini yoyaka mkati chifukwa cha kutayika kwa choziziritsira chomwe chikuyenda mu thermostat sikunganyalanyazidwe. Mu 2001, Shuai Liyan ndi Guo Xinmin a Shandong Agricultural University adapanga valavu ya thermostat ngati silinda yopyapyala yokhala ndi mabowo pakhoma la mbali, adapanga njira yotulutsira madzi kuchokera m'mabowo am'mbali ndi mabowo apakati, ndipo adasankha mkuwa kapena aluminiyamu ngati zinthu za valavu, zomwe zimapangitsa kuti pamwamba pa valavu pakhale posalala, kuti achepetse kukana ndikuwonjezera magwiridwe antchito a thermostat.
