Introduction plate heat exchanger is a new and efficient heat exchanger consists of a series of corrugated sheet metal with a certain shape made of stacked. Forming a thin rectangular plate between the various channels through half a slice of heat exchange. Plate heat exchanger is a liquid - liquid, liquid - vapor ideal heat exchange equipment. BR type devices consisting of a plate heat exchanger is fixed clamping plate?? Connector? Seal pad? Plate? Activities pressed board? Intermediate plate under the guide rod? Upper guide rod?? Clamping bolt? After prop nut components. Features a high heat transfer efficiency, low heat loss, compact and lightweight structure, accounting? Small area, easy installation and cleaning, widely used, and long service life. Pressure loss in the same case, the heat transfer coefficient than the tube changer? High heat 3-5 times, covering a third of the tube heat exchangers, heat recovery cooling, boiling cooling textile cleaning agent nitrocellulose heat recovery wool cleaning liquid heating fuel plant waste heat
