非對(duì)稱流道

不同廠商的換熱器產(chǎn)品從外觀上看不出太大的區(qū)別，但在換熱效果 L K 上起決定作用的換熱板片的結(jié)構(gòu)卻千差萬別。HF系列板型打破傳統(tǒng)的正弦對(duì)稱波紋的設(shè)計(jì)，創(chuàng)造出獨(dú)特的波形偏離式板型，板片的正反面具有不同的流通面積，通過4種板片（H，L，G，K）靈活的組合，可以形成6種流通量各異的流通道，巧妙的解決換熱性能和壓力損失之間的矛盾關(guān)系，在兩側(cè)流量1:3的條件下，可以取得兩側(cè)壓降相等。即使在兩側(cè)流量差異極大的場(chǎng)合（1:10），仍然可以取得較高的換熱系數(shù)，提高換熱器的性價(jià)比。

At first glance, the plate heat exchangers of the different providers seem to bevery similar. However, the secret of anefficient heat transfer is inside the platepack whose performance depends on a whole range of factors apart from plate size and number. Ultimately, these factors determine the size of the deviceand the operating costs. The ?skewing“-Plates are available with four different profiles each (G, H, K, L), differing in ratio of embossing depth, distance and angle of corrugation . Each of the 14 plate sizes offer six different flow gaps. When combining the  asymmetrical G, H, K, L-plates, the plate heat exchanger can beadapted optimally to the thermal case of application already in the series with limiteddiversity of types
