Pneumatic spraying yog siv los txhim kho kev ua haujlwm ntawm finned nto. Qhov tseem ceeb, nws yuav tsum txau cov hmoov nplej rau ntawm qhov chaw fin siv lub siab -ceev, txias los yog me ntsis rhuab kua uas muaj cov ntsiab lus. Txoj kev no tuaj yeem siv tsis tau tsuas yog tshuaj tsuag hlau xwb tab sis kuj alloys thiab ceramics (hlau-ceramic mix), uas ua rau cov chaw muaj ntau yam khoom. Hauv kev xyaum, kev tiv thaiv kev tiv thaiv ntawm tus fins puag yog feem ntau txwv qhov tseem ceeb hauv kev teeb tsa cov fins ntawm cov hlab.
Ib qho kev sim tau tshawb nrhiav los ntsuas cov finned tube kub exchanger ntsiab. Qhov kev sim cuam tshuam nrog txau AC- txhuas mus rau qhov chaw fin nrog ntxiv ntawm 24A dawb hluav taws xob rauv alumina. Cov ntaub ntawv sim tau raug txheeb xyuas los ntsuas qhov kev tiv thaiv tiv thaiv ntawm lub fin lub hauv paus. Sib piv cov kev tshawb fawb fin efficiency nrog cov ntaub ntawv suav, qhov xaus yog tias kev tiv thaiv tiv thaiv ntawm lub hauv paus ntawm pneumatically sprayed fins tsis muaj kev cuam tshuam loj heev rau kev ua haujlwm. Txhawm rau kom paub meej qhov no, kev tshuaj xyuas metallographic tau ua nyob rau thaj chaw hloov pauv ntawm lub hauv paus (tube) thiab qhov chaw (fin). Kev soj ntsuam ntawm thaj chaw hloov pauv tau pom tias tsis muaj microcracks lossis xau raws tag nrho qhov ntev ntawm kev sib txuas ciam teb.
Yog li ntawd, pneumatic spraying txhawb kev tsim ntawm ceg ntawm ciam teb ntawm qhov chaw thiab cov kev sib cuam tshuam yooj yim, thiab pab txhawb kev nkag mus ntawm cov hmoov hmoov rau hauv matrix. Qhov no ua rau muaj zog adhesion siab, kev sib cuag lub cev, thiab tsim cov hlau chains. Yog li ntawd, pneumatic spraying yuav siv tsis tau tsuas yog rau molding, tab sis kuj rau kho fins manufactured siv cov pa txoj kev mus rau saum npoo ntawm tshav kub exchanger hlab, thiab rau ntxiv dag zog rau lub hauv qab nto ntawm zoo tib yam fins. Nws yog foreseeable tias pneumatic spraying yuav tau lug siv nyob rau hauv zus tau tej cov compact thiab npaum tshav kub exchangers.
