Uhlalutyo lwesicelo sephepha le-bimetallic kumkhuseli we-thermal

Eyona nto ibalulekileyo kwiumkhuseli thermalyibhimetal. Namhlanje, ndiya kukuthatha ukuba uqonde ukusetyenziswa kwe-bimetal kumkhuseli we-thermal.

Indima yephepha le-bimetal kumkhuseli we-thermal kukuba: xa ubushushu buguquka, kuba i-coefficient yokwandiswa kwecala eliphezulu lokwandiswa kwe-bimetal liphezulu kakhulu kune-coefficient yokwandiswa kwecala eliphantsi lokwandisa, ukugoba kwenzeka, kwaye sisebenzisa oku kugoba. umsebenzi. kwiumkhuseli thermal.

Izinto ezishushu ze-bimetallic ekrwada zabavelisi abahlukeneyo ziyafana ngokusisiseko, i-matrix yintsimbi kunye ne-alloys yobhedu, kwaye izinto ezifana ne-nickel kunye ne-manganese zongezwa ukuze zitshintshe i-coefficients yazo yokwandisa, okukhokelela kulwandiso oluphezulu lwecala kunye nolwandiso olusezantsi lwealloys, kunye emva koko ukuqulunqwa kwezinto. Ngamanye amaxesha ii-alloys ze-master zongezwa ukwenzela ukuba utshintshe i-resistiveivity yezinto.

Ngaphambi kokudibanisa iumkhuseli thermal, ukwenza iphepha le-bimetallic linyathelo elibaluleke kakhulu. Okokuqala, i-bimetallic strip eshushu ibethelwa kwaye igqunywe kwi-sheet shape, ize ifakwe ngaphambili kwi-disc shape. Ngeli xesha, i-bimetal ye-thermal ene-dish inesenzo esisisigxina kunye nokushisa ngokutsha. Iiparameters eziphambili ze-bimetals ezimele ziqwalaselwe ngaphambi kokubetha: ukugoba okuthe ngqo, i-modulus elastic, ukuqina, ukuchaneka kwe-dimensional, resistivity, uluhlu lweqondo lokushisa. Okokuqala qwalasela uluhlu lweqondo lobushushu elinokuthi i-bimetal sheet isetyenziswe kulo, kwaye emva koko uqwalasele amandla kunye ne-torque yesenzo ekufuneka i-bimetal ivelise, kwaye ukhethe imodyuli ethile efanelekileyo yokugoba kunye ne-elastiki. Emva koko khetha ubungakanani, ukuqina kunye ne-elastic modulus ye-bimetal eshushu efanelekileyo kwinkqubo yokubumba kunye nezixhobo. Emva koko ukhethe ukuxhatshazwa okufanelekileyo ngokweemfuno zexesha langoku lomkhuseli kunye nomphumo wesigxina somthamo wokushisa.

Ngokutsho kwe-bimetal's current thermal effect formula Q = ∫t0I2Rdt, iyakwazi ukwaziwa ukuba ukukhetha i-bimetal enokumelana okuphezulu kuya kuvelisa ubushushu obuninzi, ukunciphisa ixesha lokusebenza lomkhuseli we-thermal, kunye nokunciphisa ubuncinci bokusebenza ngoku. Okuchaseneyo kuyinyaniso kwiibimetals ezinokumelana okuphantsi. Ukuchasana kwe-bimetal kuchaphazeleka ngokuxhathisa, ubungakanani kunye nobukhulu bobume.
