Bambo Doi ndi manejala wamkulu wogula pakampani yopanga makina okhomerera ku Vietnam. M’zaka 20 zakugwira ntchito, iye anaona kuti kampaniyo ikukula kuchokera ku fakitale yaing’ono kufika ku kampani yaikulu yopanga ya antchito mazana angapo. Monga kampani ya mbiri yakale, kampani yake inayamikira kwambiri luso la makinawo.
Choncho, theka la chaka chapitacho, kampani yake anayambitsa 1000W CHIKWANGWANI laser kudula makina kudula zipangizo kupanga makina kukhomerera. Patapita milungu ingapo ntchito, iye anaganiza kuti kunali koyenera kukweza mphamvu ya laser kudula makina pang'ono, kotero iye anachita kafukufuku mwatsatanetsatane pa mpweya utakhazikika kuzungulira chillers mu msika ndipo potsiriza anasankha S&A Teyu madzi chiller CWFL-1000 kwa kuziziritsa 1000W CHIKWANGWANI laser kudula makina.
S&A Teyu mpweya utakhazikika wozungulira madzi chiller CWFL-1000 idapangidwira mwapadera kuti aziziziritsa 1000W fiber laser ndipo idapangidwa ndi machitidwe awiri owongolera kutentha omwe amatha kuziziritsa chipangizo cha fiber laser ndi cholumikizira cha QBH / Optics nthawi imodzi. Kwa ogwiritsa ntchito 1000W fiber laser, S&A mpweya wa Teyu utazirala mozungulira madzi ozizira CWFL-1000 ndi njira yabwino yochotsera kutentha kowonjezera ku fiber laser.
