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
