采用高速的冷的或稍微加溫的含微粒的流體給翅片表面噴鍍粉末粒子。用該方法不*可噴涂金屬還能噴涂合金和陶瓷(金屬陶瓷混合物)，從而得到各種不同性能的表面。通常在實(shí)踐中翅片底面的接觸阻力是限制管子加裝翅片的因素之一。為了評估翅片管換熱器元件進(jìn)行了試驗(yàn)研究。試驗(yàn)是采用在翅片表面噴涂ac－鋁，并添加了24a白色電爐氧化鋁。將試驗(yàn)所得數(shù)據(jù)加以整理，便可評估翅片底面的接觸阻力。將研究的翅片的效率與計(jì)算數(shù)據(jù)進(jìn)行比較，得出的結(jié)論是：氣動(dòng)噴涂翅片的底面的接觸阻力對效率無實(shí)質(zhì)性影響。為了證實(shí)這一點(diǎn)，又對基部(管子)與表面(翅片)的過渡區(qū)進(jìn)行了金相結(jié)構(gòu)分析。對過渡區(qū)試片的分析表明，連接邊界的整個(gè)長度上無不嚴(yán)密性的微裂紋。所以，氣動(dòng)噴涂法促進(jìn)表面與基本相互作用的分支邊界的形成，能促進(jìn)粉末粒子向基體的滲透，這就說明了附著強(qiáng)度高，有物理接觸和金屬鏈形成。因而氣動(dòng)噴涂法不但可用于成型，還可用來將按普通方法制造的翅片固定在換熱器管子的表面上，也可用來對普通翅片的底面進(jìn)行補(bǔ)充加固。青海換熱器誠信企業(yè)板式換熱器也就是板式熱交換器。</p><div
