Foornada kuleyliyaha Microwave waxay inta badan ka kooban tahay nidaamka la socodka, nidaamka xakamaynta, sanduuqa dahaarka, makiinadaha microwave-ka, sanduuqa kuleylka iyo haanta kaydinta gaaska.Sanduuqa kuleyliyaha wuxuu ka samaysan yahay saxan muraayad bir ah.Biyaha qaboojinta waxay ku qulquli karaan sandwich inta u dhaxaysa laba lakab oo saxan bir ah si loo gaaro qaboojinta sanduuqa kuleylka.
1. Mabaadi'da mikrowave-ka ee maaddooyinka dhoobada ah
Dareen-celinta walxaha microwave-ka waxaa loo qaybin karaa afar xaaladood: milicsiga mikrowaytka gudbinta microwave;nuugista microwave;nuugista qayb ahaan microwave.Inta badan biraha waxay ku dhacaan qaybta koowaad, halka dhammaan walxaha dhalada iyo dhoobada ay ku dhacaan saddexda qaybood ee dambe.Marka jidhka dhoobada ah la dhigo beerta microwave, awoodda la nuugo waxaa lagu muujin karaa isla'egta soo socota:
P = (2π fε ) ( E2/ 2) tan δ， Marka microwave-ku uu galo walxaha, xooggiisa ayaa hoos u dhacaya qoto-dheeraanta dhexgalka.Fogaanta u jirta dusha walaxda ilaa 1/ e ee tamarta microwave-ka waxaa lagu qeexaa sida gunta hoose ee Dp ee microwave:
3λ 0
DP = π tan δ (ε r/ε 0) 1/ 2
8. 686
Halkee, P waa awoodda microwave ee uu nuugo jidhka dhoobada;F waa inta jeer;ε waa isku-dhafka dielectric joogto ah;λ 0 waa dhererka hirarka microwave ee faaruqinta;E waa xoogga korontada;tan δ waa tangent luminta ceramics dielectric;Tangent luminta (saamiga qodobka lumitaanka ee joogtada ah ee dielectric) waxaa badanaa loo isticmaalaa in lagu muujiyo kartida isku dhafka ah ee maaddada mikrowave. Inta badan qiimaha tangent luminta waa, awoodda isku-xirnaanta ee udhaxeysa walxaha iyo microwave waa.
2. Naqshadaynta foornada kuleylka sare ee microwave
Foornada kuleyliyaha Microwave waxay inta badan ka kooban tahay nidaamka la socodka, nidaamka xakamaynta, sanduuqa dahaarka, makiinadaha microwave-ka, sanduuqa kuleylka iyo haanta kaydinta gaaska.Sanduuqa kuleyliyaha wuxuu ka samaysan yahay saxan muraayad bir ah.Biyaha qaboojinta waxay ku qulquli karaan sandwich inta u dhaxaysa laba lakab oo saxan bir ah si loo gaaro qaboojinta sanduuqa kuleylka.Dareemka heerkulka aan isticmaalno waa RAYR3I1MSCL2U heerkulbeegga infrared ee shirkadda American leitai.Nidaamka xakamaynta wuxuu xaqiijin karaa xakamaynta gacanta iyo xakamaynta tooska ah.Si looga hortago in albaabka foornada mikrowave xiran ka dib foornada kululaynta microwave ka albaabka foornada oo ka soo daadanayaan bannaanka u dhexeeya godka, marka lagu daro kulaylinta albaabka foornada ee processing iyo wax soo saarka si loo hubiyo sax cabbir sare iyo saxnaanta shirka, waxaan in albaabka foornada mikrowayka ee lagu rakibay agagaarka qaab dhismeedka jeexdin ee choke, qaab dhismeedkani wuxuu si wax ku ool ah u yareeyn karaa daadinta microwave-ka.Xulashada, naqshadaynta goobta iyo dahaarka matoorka microwave-ka ayaa ah arrimaha ugu muhiimsanfoornada sinteringnaqshadeynta.
3. Xulashada matooriyaha microwave-ka
Mag netron, Klystron iyo Gyrotron ayaa guud ahaan lagu doortay aaladaha kuleyliyaha microwave-ka.Sida "wadnaha" qalabka mikrowave, doorashadu waxay si toos ah u saameyn doontaa waxqabadka iyo qiimaha qalabka oo dhan.Inta jeer ee caadiga ah ee loo isticmaalo aaladda mikrowave waa:
915 MHz, 2.45 GHz, 6 GHz, 28 GHz iyo 60 GHz, iwm. Guud ahaan, magnetron waxa loo dooran karaa koronto dhaliyaha mikrowave ee soo noqnoqoshada hoose sida 915 MHz iyo 2.45 GHz, 6 GHz waxa loo dooran karaa sida tuubada xawaaraheeda, iyo tamar sare sida 28 GHz iyo 60 GHz waxaa loo dooran karaa gariiradda magnetic.
Sida soo noqnoqda iyo awoodda matoorayaasha microwave ee kala duwan ay korodho, saamigooda qiimaha ($/ Watt) ayaa si weyn u kordhin doona.Haddii koronto-dhaliyaha microwave-ka sare looga baahan yahay naqshadeynta, waxaa lagu talinayaa in la isticmaalo soo noqnoqoshada isku midka ah iyo koronto-dhaliye hoose si loo helo awood sare.
4.Naqshadda qaab-dhismeedka dahaadhka
Qaab dhismeedka dahaarka ee inta badan lagu isticmaalo foornada mikrowave waa nooca budada la aasay iyo nooca sanduuqa.Qaab dhismeedka daboolka budada ah ee la aasay ayaa leh faa'iidooyinka saamaynta dahaarka wanaagsan.Si kastaba ha ahaatee, marka shaybaarada lagu miiray heerkul sare, ku dheggan inta u dhaxaysa shaybaarada iyo budada la aasay way fududahay inay dhacdo.Ka dib marka shaybaarada la miiro, xiriir toos ah ayaa dhici doona.Laakiin qaabkani uma fiicna sida qaab dhismeedka dahaarka budada ah ee la aasay.Isku-dubbaridka sifooyinka labada qaab-dhismeed ee daboolka, waxaanu naqshadeynay qaab-dhismeedka qaab-dhismeedka sanduuqa.
