Pogwiritsa ntchito kuwonjezereka kwa ma lasers a fiber, kudalirika kwa ma lasers a fiber kwachititsa chidwi kwambiri, kuphatikizapo kudalirika kwa ntchito zotulutsa laser, kudalirika kwa zipangizo zamagetsi, kudalirika kwa zipangizo zamagetsi, kudalirika kwa machitidwe, etc. Dikirani.Zambiri mwa izi zimagwirizana kwambiri ndi kutentha kwa laser palokha.Kuphatikiza apo, kutentha kumakhudza kwambiri magwiridwe antchito a laser, makamaka mphamvu yotulutsa ndi kukhazikika kwa laser.
Kutentha kwa fiber laser makamaka kumachokera ku gwero la mpope ndi polowera phindu.Kwa gwero la mpope, kutembenuka kwake kumakhala pafupifupi 50%, zomwe zikutanthauzanso kuti mphamvu yofanana ndi mphamvu yotulutsa kuwala imapangidwa mwa mawonekedwe a kutentha.Ngati kutentha sikungatheke panthawi yake, kutentha kwa chipangizo chamkati kumakwera mofulumira, ndipo kutalika kwapakati pa laser kumasuntha pamene kutentha kumakwera.Kuti pakhale phindu, kuwala kwa mpope kukalowa mu fiber yogwira, gawo limodzi lokha limasandulika kukhala laser linanena bungwe, ndipo zina zonse zimasandulika kukhala mphamvu ya kutentha.Kutentha kwamphamvu kumawonjezera kutentha kwa sing'anga yopeza, zomwe zimapangitsa kufutukuka kwa sipekitiramu ya fluorescence ndi moyo waufupi wotulutsa modzidzimutsa, potero kuchepetsa kutembenuka kwamphamvu.Chifukwa chake, kasamalidwe kamafuta kamakhala ndi tanthauzo losanyozeka kwa ma fiber lasers.Pakalipano, matekinoloje omwe amagwiritsidwa ntchito kawirikawiri amatenthedwa makamaka ndi mpweya wozizira komanso madzi ozizira.Pakati pawo, ukadaulo wotenthetsera kutentha kwa mpweya umagwiritsidwa ntchito makamaka pama lasers otsika mphamvu komanso ma laser opitilira mphamvu.Ma lasers ambiri apakati komanso apamwamba kwambiri amagwiritsa ntchito kutentha kwamadzi ozizira ngati njira yayikulu yowotcha.
Njira ziwiri zochotsera kutentha
1. Kuziziritsa madzi
Monga momwe dzinalo limatanthawuzira, kuziziritsa kwa madzi ndiko kugwiritsa ntchito madzi kuchotsa kutentha kudzera muzitsulo zotentha (monga mbale yoziziritsira madzi).Mfundo yake yogwirira ntchito ndi yophweka kwambiri, ndiko kuti, madzi ozizira mu chiller amayenda mu chotenthetsera kutentha kupyolera mu chitoliro cha madzi, ndiyeno amatuluka kuchokera ku doko lina la exchanger kutentha, ndiyeno amabwerera ku chiller kupyolera mu chitoliro cha madzi. .Kutentha kumatengedwa kuchokera mkati mwa laser.
Njira yothetsera kutentha kwa madzi imakhala ndi dongosolo losavuta komanso losavuta kusamalira;mphamvu yochotsa kutentha ndi yamphamvu komanso kufanana kwa kutentha ndikwabwino.Kuzizira kwa laser kumatha kupitsidwanso pogwiritsa ntchito chozizira chokhala ndi kuzizira kokulirapo.Pakali pano, pali opanga oposa 500 kuphatikiza ndi kugulitsa m'manja laser kuwotcherera makina pa msika, ndipo iwo zambiri ntchito madzi kuzirala.Komabe, kuwonjezera pa laser yokha, makina owotcherera a laser okhala ndi manja okhala ndi kuziziritsa kwamadzi amafunikiranso zoziziritsa kukhosi ndi madzi, zomwe zimabweretsa kuwonjezeka kwakukulu kwa voliyumu yonse ndi kulemera kwa zida, komanso malo ogwiritsira ntchito ochepa.
2. Kuziziritsa mpweya
M'njira yotakata, kutentha kozizira ndi mpweya kumatanthawuza kugwiritsa ntchito mafani kuti apititse patsogolo kayendedwe ka mpweya ndi kutentha kwathunthu mkati mwa makina.Ndi kusintha kwaukadaulo, opanga ma laser akuluakulu ayamba kupondaponda pagawo la kuziziritsa kwa mpweya ndi kutulutsa kutentha.Mu June chaka chatha, padziko lonse CHIKWANGWANI laser chimphona I anapezerapo mpweya utakhazikika LightWELD 1500W m'manja laser kuwotcherera mankhwala;mu August, GW anapezerapo mpweya utakhazikika A1500W wanzeru laser kuwotcherera makina ku China;mu Okutobala, kampani ya Reci idatulutsanso makina owotcherera a laser a FCA1500.laser.

(2) Tetezani chitoliro cha radiator kuti muthe kutentha
Kutentha kwa kutentha kwa radiator ya chitoliro cha kutentha kumatanthawuza kuti chitoliro cha kutentha chimadalira kusintha kwa gawo la madzi ogwira ntchito mkati mwake kuti akwaniritse kutentha kwa kutentha.Madzi awa amakhala ndi malo owira pang'ono ndipo ndi osavuta kusungunuka.Mapeto amodzi a chitoliro cha kutentha ndi mapeto a evaporation, omwe amagwirizanitsidwa ndi kutentha kwa kutentha mkati mwa laser;mapeto ena ndi mapeto a condensation, omwe amagwirizanitsidwa ndi kutentha kwakunja kwa kutentha ndi fani.Khoma la chubu lili ndi chingwe chothira madzi, chomwe chimapangidwa ndi zida za capillary porous.Laser ikatenthedwa, kumapeto kwa mpweya kumatenthedwa, madzi ogwira ntchito amatuluka mofulumira, nthunzi imayenda mpaka kumapeto kwa condensing pansi pa kusiyana kwa kupanikizika, ndipo kutentha kumatulutsidwa, komwe kumatulutsidwa kudzera mu fani;panthawi imodzimodziyo, nthunziyo imasungunukanso kukhala madzi, ndipo madziwo amabwerera ku gawo la evaporation kupyolera mu chingwe.(Ngati ndi chitoliro cha kutentha kwa mphamvu yokoka, palibe chingwe, ndipo madzi amamatira ku khoma la chubu ndikubwerera ku gawo lapansi la evaporation ndi mphamvu yokoka).Kuzungulira uku sikuyima, ndipo kutentha kumasamutsidwa kuchokera mkati mwa laser kupita kunja.

(3) Kuziziritsa ndi kuziziritsa kompresa
Firiji ya Compressor ndi mfundo yoziziritsira kutentha: Compressor imakakamiza firiji, imatembenuza firiji kukhala yotentha kwambiri komanso mpweya wothamanga kwambiri, ndikuthamangira ku condenser yakunja.Kutentha kwakukulu ndi mpweya wothamanga kwambiri umachepetsedwa kukhala kutentha kochepa ndi madzi othamanga kwambiri, ndipo kutentha kopangidwa ndi liquefaction kumatulutsidwa kunja kwa makina ndi fan.Refrigerant yamadzimadzi yotsika kwambiri komanso yothamanga kwambiri imadetsedwa kudzera mu valavu yowonjezera ndipo imakhala yotsika kwambiri, yotsika kwambiri, yosavuta kutulutsa mpweya, ndipo imapita ku evaporator yamkati.Evaporator imatenga kutentha kuti muchepetse kutentha kwa mkati mwa laser kuti akwaniritse kuziziritsa, ndiyeno refrigerant imatuluka kutentha kwambiri komanso mpweya wochepa.Refrigerant ya gasi yomwe imawululidwa ndi evaporator imapanikizidwa ndi kompresa kachiwiri ndikuzungulira mmbuyo ndi mtsogolo, zomwe zimazindikira kutayika kwa kutentha mkati mwa makinawo.

Kuyerekeza njira zingapo zoziziritsa
Kapangidwe ka kuzizira kwa fan ndi kosavuta.Imangofalitsa kutentha mu sinki ya kutentha kupita ku sinki ya kutentha, ndiyeno imagwiritsa ntchito kusiyana kwa kutentha pakati pa sinki ya kutentha ndi mpweya wozungulira kuti iwononge kutentha kupyolera mu kukakamiza kwa fani.Kutentha kozungulira kukakhala kokwera kwambiri m'chilimwe, kusiyana kwa kutentha pakati pa sink ya kutentha ndi mpweya kumakhala kochepa kwambiri, ndipo mphamvu yotulutsa kutentha idzachepetsedwa kwambiri.Imatha kungochotsa kutentha kwapang'onopang'ono, imakhudzidwa kwambiri ndi chilengedwe, ndipo sichingathe kuwongolera bwino kutentha.Ubwino wake ndikuti zida zonse ndi dongosolo lowongolera ndizosavuta.
Poyerekeza ndi njira yosavuta yoziziritsira mafani, radiator ya chitoliro cha kutentha imakhala ndi mapaipi ambiri otentha, kotero mawonekedwe ake ndi ovuta.Zimadalira kutuluka kwa nthunzi ndi condensation ya zinthu zogwirira ntchito kuti zisunthire mwamsanga kutentha kuchokera kumalo otentha kupita kumalo otentha ndikutaya kutentha mumlengalenga kupyolera mu fani.Zimakhalanso za kutentha kwapang'onopang'ono, komwe sikungathe kuwongolera bwino kutentha ndipo kumasokonezedwa kwambiri ndi kutentha kozungulira.
