Plate heat exchanger is a new highly 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. Compared with the conventional shell and tube heat exchanger, at the same flow resistance and pump power consumption, much higher heat transfer coefficient has replaced shell and tube heat exchanger within the scope of the trend. Plate for plate heat exchanger is pressed against a metal sheet into a heat exchange plate having a corrugated shape and then stacked, with a splint, bolt made of a heat exchanger. Narrow and tortuous passage of the working fluid between the two plates forming flowing. Hot and cold fluid passes through the flow channel, the middle of a separate fluid compartment plates, and carried by the plate heat exchanger.
Under normal circumstances, we mainly to distinguish the structure of plate heat exchanger, which is based on the shape to distinguish, can be divided into four categories: 1, detachable plate heat exchanger (called with sealing gasket plate heat exchanger) , 2, welded plate heat exchangers, 3, spiral plate heat exchanger, 4, coil heat exchangers (also known as cellular heat exchanger 5).
Plate heat exchanger comprises two main frame and plate components. Thin sheet made from various materials with various forms of pressure abrasive into corrugated shapes, and in the four corners of the opening plate angular aperture for the medium flow path. Perimeter and corner of the plate hole sealed with a rubber gasket. Framework consists of fixed clamping plate, activities pressing plate, the upper and lower guide rod and clamping bolts and the like. Plate heat exchanger is superimposed in the form of plates mounted on the fixed clamping plate, pressing the middle plate activity, and then clamped together with the clamping bolt.
Plate heat exchanger with a heat transfer coefficient, pressure drop is small, compact, light weight, small footprint, easy area and process combinations, parts versatility, choose materials, and easy to implement wide-scale production, etc., have been widely used in food, machinery, metallurgy, petrochemical and shipbuilding, and become the city's leading central heating engineering heat transfer equipment. In order to ensure the normal operation of the plate heat exchanger, extended key components (such as plates, pads) of life, understand the emergence of plate heat exchanger failure and its causes and treatment is very important.
