Plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates to exchange heat through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, easy installation and cleaning, wide application and long service life.
There are two main types of plate heat exchangers: frame type (removable type) and brazed type. The plate types are mainly three kinds of herringbone corrugated plate, horizontal flat corrugated plate and knob-shaped plate.
Principle of operation
The plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking metal plates with a certain corrugated shape. The structure includes gaskets, compression plates (movable end plates, fixed end plates) and frames (upper and lower guide rods). , Front pillar), the plates are sealed and guided by sealing gaskets, separating the cold/hot two fluid channels, the cold/hot heat exchange medium flows through the respective channels, and heats the separated plates Exchange to reach the temperature required by the user.
Each plate has openings at the four corners, which are assembled into a plate bundle to form a fluid distribution pipe and a collection pipe. After the heat exchange of the cold/heat medium, the return flow from the respective collection pipe is recycled.
