非对称流道

不同厂商的换热器产品从外观上看不出太大的区别，但在换热效果 L K 上起决定作用的换热板片的结构却千差万别。HF系列板型打破传统的正弦对称波纹的设计，创造出独特的波形偏离式板型，板片的正反面具有不同的流通面积，通过4种板片（H，L，G，K）灵活的组合，可以形成6种流通量各异的流通道，巧妙的解决换热性能和压力损失之间的矛盾关系，在两侧流量1:3的条件下，可以取得两侧压降相等。即使在两侧流量差异极大的场合（1:10），仍然可以取得较高的换热系数，提高换热器的性价比。

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
