Introduction To The Structure Of Plate Heat Exchanger

Plate heat exchangers are widely used in heating, cooling, and condensation. The plate heat exchanger is composed of a set Introduction to the structure of plate heat exchangerof corrugated parallel metal plates. There are passage holes at the four corners of the plates. The plates are clamped in a frame with a fixed plate attached to a pipe and a movable compression plate. . These connecting pipes are aligned with the channel holes on the plate and are connected to the external pipelines of the two liquids for heat exchange. The heat transfer plate and the movable pressing plate are suspended under the top load-bearing beam and aligned and positioned by the bottom cross beam. Heat transfer plates, sealing gaskets, compression plates, guide rails and clamping bolts are the main components of the plate heat exchanger.

(1) The heat transfer plate is a component that mainly plays the role of heat exchange. Generally, the corrugation is made into a herringbone shape. According to the different fluid medium, the material of the heat transfer plate is different, and most of them are made of stainless steel and titanium.

(2) Compression plates at both ends. The two are mainly to clamp and press all the heat transfer plates to ensure that the fluid medium does not leak.

(3) Sealing gasket. It mainly serves as a seal between the hot plates. The leakage of the plate heat exchanger is mostly caused by the dislocation or aging of the gasket.

(4) Clamping bolts are mainly used to clamp the head and heat exchange plate. The clamping bolts are generally through-threaded. When pre-tightening the bolts, a torque wrench must be used to make the torque of the fixed plate uniform.
