Plate type heat exchanger advantages and disadvantages

Plate type heat exchanger advantages and disadvantages:

   Plate heat exchangers have their own unique characteristics due to the particularity of their flow channels. It is these features that improve the Plate type heat exchanger advantages and disadvantagesheat transfer coefficient, reduce the mass transfer resistance, and enhance the heat transfer effect compared to other forms of heat transfer.The advantages and disadvantages of the plate heat exchanger are analyzed below. Plate heat exchangers generally have the advantages of low heat loss, high heat exchange efficiency, small size, light weight, and convenient maintenance. At the same time, plate heat exchangers are relatively inexpensive and can be accepted by most manufacturers, and they are widely used. In general, it can reach 3000-4000W/mK, which is 3-5 times that of shell-and-tube heat exchangers, and even 6000W/M.K in some cases. Moreover, the thickness of the metal sheet used in the plate type heat exchanger is generally 0.6-0.8 mm, but the heat exchange effect is good.. In addition, the equipment can withstand temperatures up to 180℃ and pressure resistance of 2 MPa. It has high corrosion resistance and is economically efficient in low-grade heat recovery. In particular, it can achieve a variety of dielectric heat exchanges by increasing the number of separators. These advantages have won a large market for plate heat exchangers. However, it is undeniable that there are still some shortcomings in the use of the panel heat exchanger due to the limitations of current technology and certain conditions. For example, high temperature resistance and pressure resistance are not very strong, and can not be used for some ultra-high temperature or complex fluids: due to the small thickness of the metal sheet, the narrow flow path, the large particulate matter cannot pass. It is believed that with the deepening of research and development, these problem will surely be solved
