The stainless steel metal plates of the plate heat exchanger are inserted and assembled in a mutually inverted mode, so that a mesh contact can be formed so that the fluid in the channel becomes a mesh fluid. The plate heat exchanger is a heat exchanger that takes liquid, and the air cooler is a heat exchanger that takes air. In addition to the difference in appearance, the medium and the corresponding material are also different. What is the difference between a plate heat exchanger and an air cooler?
(1) Basic principles of plate heat exchangers and air coolers
The plate heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. An air cooler is a heat exchanger that uses air to cool hot fluid. The hot fluid in the tube exchanges heat with the air outside the tube through the tube wall and fins, and the air used is usually supplied by a ventilator.
(2) Basic structure of plate heat exchanger and air cooler
The plate heat exchanger is a combination of frame plates, stainless steel plates and sealing gaskets. The two media A and B carry out their own heat exchange equipment through corresponding channels. The materials used are generally 304 and 316L as the plate material. The air cooler is mainly composed of tube bundles, brackets and fans. The hot fluid of the air cooler flows in the tube, and the air blows through the tube bundle. The commonly used material is aluminum, which is wound or inlaid on the light pipe.
(3) Application fields of plate heat exchanger and air cooler
Plate heat exchangers have been widely used in metallurgy, mining, petroleum, chemical, electric power, medicine, food, chemical fiber, paper, textile, shipping, heating and other sectors, and can be used for heating, cooling, evaporation, condensation, sterilization and disinfection. Air (wind) coolers are mainly used for mobile machinery (excavators, loaders, forklifts, cranes, combine harvesters, road construction machinery, construction machinery), and use air cooling to force the working medium to cool to the required temperature.
