釬焊板式換熱器， 是由一系列具有一定波紋形狀的金屬片疊裝經(jīng)過釬焊加工而成的一種新型高效換熱器。各種板片之間形成薄矩形通道，通過半片進(jìn)行熱量交換。它與常規(guī)的管殼式換熱器相比，在相同的流動(dòng)阻力和泵功率消耗情況下，其傳熱系數(shù)要高出很多，在適用的范圍內(nèi)有取代管殼式換熱器的趨勢。
A brazed plate heat exchanger is a new type of high efficiency heat exchanger made of a series of metal sheets with corrugated shapes and brazed by brazing. Thin rectangular channels are formed between the plates, and heat exchange is carried out by halves. Compared with the conventional shell and tube heat exchangers, the heat transfer coefficient is much higher in the same flow resistance and pump power consumption, and has a tendency to replace the shell and tube heat exchangers in the applicable range.
