Uyilo lweThermal kunye noLawulo

Ukushisa (ukunyuka kobushushu) bekusoloko kulutshaba oluzinzile kunye nokusebenza okuthembekileyo kwemveliso. Xa ulawulo lwe-thermal R & D abasebenzi benza umboniso wemveliso kunye noyilo, kufuneka banakekele iimfuno zamashishini ahlukeneyo emarike kwaye bafezekise ibhalansi engcono phakathi kwezibonakaliso zokusebenza kunye neendleko ezibanzi.

Ngenxa yokuba izinto ze-elektroniki zichatshazelwa ngokusisiseko kwiparamitha yeqondo lobushushu, njengengxolo ye-thermal ye-resistor, ukuncipha kwe-PN junction voltage ye-transistor phantsi kwefuthe lokunyuka kobushushu, kunye nexabiso elingahambelaniyo le-capacitor kwiqondo lobushushu eliphezulu neliphantsi. .

Ngokusetyenziswa okuguquguqukayo kweekhamera zokujonga i-thermal, abasebenzi be-R&D banokuphucula kakhulu ukusebenza kakuhle kwayo yonke imiba yoyilo lokuphelisa ubushushu.

Ulawulo lobushushu

1. Ukuvavanya ngokukhawuleza umthwalo wobushushu

Ikhamera ye-Thermal imaging inomfanekiso obonakalayo wokusasazwa kobushushu bemveliso, inceda abasebenzi be-R&D ukuba bavavanye ngokuchanekileyo ukuhanjiswa kwe-thermal, bafumane indawo enomthwalo ogqithisiweyo wobushushu, kwaye benze uyilo olulandelayo lokutshabalalisa ubushushu lujolise ngakumbi.

Njengoko kubonisiwe kulo mfanekiso ungezantsi, i-redder ithetha ukuphakama kweqondo lokushisa..

2. Uvavanyo kunye nokuqinisekiswa kweskimu sokutshatyalaliswa kobushushu

Kuya kuba neentlobo ezahlukeneyo zokutshatyalaliswa kobushushu kwinqanaba lokuyila. Ikhamera yokulinganisa i-thermal inokunceda abasebenzi be-R & D ngokukhawuleza kwaye intuitively bavavanye izikimu zokulahla ubushushu kunye nokumisela indlela yobugcisa.

Umzekelo, ukubeka umthombo wobushushu ocacileyo kwiradiyetha enkulu yesinyithi kuya kuvelisa i-thermal gradient enkulu kuba ubushushu buqhutywa kancinci nge-aluminiyam ukuya kumaphiko (fins).

Isicwangciso sabasebenzi be-R&D sokufakela imibhobho yobushushu kwirediyetha ukunciphisa ubukhulu bepleyiti yeradiyetha kunye nommandla weradiyetha, ukunciphisa ukuxhomekeka kwi-convection ngenkani ukuze kuncitshiswe ingxolo, nokuqinisekisa ukusebenza okuzinzile kwexesha elide kwemveliso. Ikhamera yokujonga i-thermal inokuba luncedo kakhulu kwiinjineli ezivavanya ukusebenza kwenkqubo

Umfanekiso ongasentla uyachaza:

► Amandla omthombo wobushushu 150W;

►Umfanekiso osekhohlo: i-aluminium yendabuko yokushisa i-sink, ubude be-30.5cm, ubukhulu besiseko 1.5cm, ubunzima be-4.4kg, kunokufunyanwa ukuba ubushushu busasazwa ngokuthe ngcembe kunye nomthombo wobushushu njengeziko;

►Umfanekiso ochanekileyo: I-heat sink emva kokuba i-5 yokushisa imibhobho ifakwe, ubude buyi-25.4cm, ubukhulu besiseko ngu-0.7cm, kwaye ubunzima buyi-2.9kg.

Xa kuthelekiswa nobushushu bendabuko, izinto eziphathekayo ziyancipha nge-34%. Inokufunyanwa ukuba umbhobho wobushushu unokuthatha ubushushu be-isothermally kunye nobushushu be-radiator Ukuhanjiswa kufana, kwaye kufunyenwe ukuba imibhobho yokushisa e-3 kuphela efunekayo ekuqhubeni ubushushu, enokunciphisa ngakumbi iindleko.

Ngaphaya koko, abasebenzi be-R&D kufuneka bayile uyilo kunye noqhagamshelwano lomthombo wobushushu kunye neradiyetha yombhobho wobushushu. Ngoncedo lweekhamera ze-infrared thermal imaging, abasebenzi be-R & D bafumanisa ukuba umthombo wokushisa kunye ne-radiator unokusebenzisa imibhobho yokushisa ukuze iqonde ukuhlukaniswa kunye nokuhanjiswa kobushushu, okwenza uyilo lwemveliso lube bhetyebhetye.

Umfanekiso ongasentla uyachaza:

► Amandla omthombo wobushushu 30W;

►Umfanekiso osekhohlo: Umthombo wobushushu unxibelelana ngokuthe ngqo nesitya sokushisa esiqhelekileyo, kwaye iqondo lobushushu leqondo lokushisa libonisa ukusabalalisa okucacileyo kwe-thermal gradient;

►Umfanekiso ochanekileyo: Umthombo wokushisa uhlukanisa ukushisa kwi-heat sink ngokusebenzisa umbhobho wokushisa. Inokufunyanwa ukuba umbhobho wokushisa uhambisa ukushisa kwe-isothermally, kwaye ubushushu bobushushu bobushushu busasazwa ngokulinganayo; iqondo lokushisa ekupheleni kweqondo lokushisa liyi-0.5 ° C ngaphezu kwesiphelo esisondeleyo, kuba i-heat sink itshisa umoya ojikelezayo Umoya uphakama kwaye uqokelele kwaye ushushu ekupheleni kwe-radiator;

► Abasebenzi be-R&D banokuluphucula ngakumbi uyilo lwenani, ubungakanani, indawo, kunye nokuhanjiswa kwemibhobho yobushushu.
