The heat recovery rate of the plate exchange heat exchanger is very high

Date:2020-06-29

Heat exchangers are very widely used around us, everyone has more or less contact, and the types of heat exchangers are also diverse. One of the more commonly used types of heat exchangers is plate exchange heat exchange. Device.

 

The plate-exchanger 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.

 

Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, it covers an area of ​​one third of the tube heat exchanger, and the heat recovery rate can be as high as 90%. There are two main types of plate heat exchangers: frame type (removable type) and brazed type. The plate types are mainly three types: herringbone corrugated plate, horizontal flat corrugated plate and knob-shaped plate.

 

 

Plate Exchange Heat Exchanger

 

Fire protection: A heat exchanger is a tool that transfers heat from one source to another. The two devices are touch or separated by a wall. Heat exchangers are used to control the temperature in sewage pipes, air conditioners or refrigerators, and are also commonly used in cars and buildings. Some industries require heat exchangers every day to prevent fires and damage, and are also used for residential or industrial liquid heating and cooling needs involving units. The water used in the water tank is used for energy. Liquids used in any industry, such as food or medical, can use plate heat exchangers when necessary. Plate heat exchangers are a type of mobile equipment. Heat transfer between metal plates. Unlike traditional heat exchangers, the plate type is preferred because the liquid is spread over more surfaces, thereby increasing the exchange rate. The metal tubes of this heat exchanger are used to heat the fluid.

 

Improving heat transfer: According to different external and internal components, plate heat exchangers are welded together by welding plates, exchange plates are welded together, and the brazed plate structure model is vacuum brazed. Different heat exchangers have different internal parts. In many cases, the smaller part works better. Some chambers are designed to be thin, so that most of the liquid contacts the plate, improving heat transfer. Smaller coils can better withstand extreme pressures, and plate heat exchangers used in a variety of ways are advantageous. It is durable, portable and easy to maintain. The entire system works with different liquid principles and does not take up too much space, the plates are easily separated and cleaned. Choose the best exchange and understand the various design and operating environments.
