产品用途
板式热交换器用于广泛的各类传热应用需求,如制冷、采暖、工业加热和冷却等。
板式换热器构造
钎焊板式换热器基本结构是由前后端板和中间波纹板构成。接头可根据实际应用定制。波纹板在真空钎焊过程中,各波纹板间的每个接触点处形成一个焊点。板式热交换器包含2个独立的流道,换热介质通过流道板四角位置开孔形成的孔道被导入板组,并分配到波纹状流道板之间形成的流道中进行热交换。
材质
钎焊板式换热器的板材有304 和 316 两种不锈钢
压力
铜钎焊板式热交换器较大设计压力: 30 bar / 45 bar
镍钎焊板式热交换器较大设计压力: 20 bar
钎焊板式换热器
钎焊换热器引入的一种创新的、**的不等流道设计,这种不等流道意味着通道体积在冷热两方面是不同的。
这有助于好地利用两侧的允许压降,如果有不同的流量或不同的流体性质,例如油和水或在两侧需不同的允许压降。
这样,就可以优化传热,从而使单元中换热板片(传热面积)的数量降到较低,在某些情况下,相同的负载下换热板片的数量较多可减少25%。一次侧的通道体积比二次侧大25%。
