，選擇的厚度不同，價(jià)格也略微有些偏差。板片的波紋形式不同會(huì)對板式熱交換器的傳熱及流動(dòng)阻力有較大影響，根據(jù)不同工況場合使用不同的波紋板片，一般以人字形波紋板和水平平直波紋板為主，價(jià)格也會(huì)有所不同。當(dāng)生產(chǎn)上要求改變工藝條件和產(chǎn)量時(shí)，增減板片的數(shù)量或改變板片組裝流程通道形式，這些操作都會(huì)影響價(jià)格的高低。
　　
　　In addition, the thickness of the plate is usually in the range of 0.5-1.5. According to the requirements of working conditions, the thickness of the plate is different, and the price is slightly deviated. The different corrugated forms of plate have great influence on heat transfer and flow resistance of plate heat exchanger. According to different working conditions, different corrugated plates are used. Generally, herringbone corrugated plates and horizontal straight corrugated plates are the main ones, and their prices are also different. When the production requirements change the process conditions and output, increasing or decreasing the number of sheets or changing the form of sheet assembly process channel, these operations will affect the price.
