船用板式熱交換器的板片結(jié)構(gòu)直接影響了熱交換器的性能。本文將對(duì)現(xiàn)有的一系列板片參數(shù)對(duì)熱交換器性能的影響進(jìn)行探討，以求為進(jìn)一步的研究提供一些借鑒。由傳熱系數(shù)的表達(dá)式可知，板片的厚度δ越小，熱交換器的傳熱效果越好，船用板式熱交換器的標(biāo)準(zhǔn)提出熱交換器的板片厚度在～，目前行業(yè)薄的鈦板板片已經(jīng)達(dá)到。板片再做薄對(duì)提高換熱效果不會(huì)太明顯，主要是為了減少成本，降低耗材，但薄板片在壓制后強(qiáng)度會(huì)相對(duì)減小。船用板式熱交換器提高k值的主要方法之一是提高板片兩側(cè)換熱介質(zhì)表面的流體擾動(dòng)程度。熱交換器的板片通常加工成人字波紋板，人字角的大小對(duì)傳熱和流體阻力影響很大。人字角大的板片傳熱系數(shù)高、流體阻力亦大；反之人字角小的板片傳熱系數(shù)和阻力都低。120°人字角的波紋傳熱效果好，角度變小或者變大，傳熱效率都會(huì)變低，通常的中央冷卻器與缸套水冷卻器采用120°人字角板片，以達(dá)到大的換熱效果。在船用滑油冷卻器中，由于滑油的粘度高于水的粘度，如果全使用120°大夾角的板片會(huì)造成流體阻力大，而60°小夾角板片的傳熱系數(shù)低。因此滑油冷卻器往往使用2種板片混裝的方式，在允許壓降的情況下，換熱混合設(shè)計(jì)，換熱面積可達(dá)更優(yōu)效果。
