What are the advantages and disadvantages of plate heat exchangers? A brazing plate heat exchanger manufacturer tells you.

Brazed plate heat exchanger manufacturers tell you what are the advantages and disadvantages of plate heat exchangers? Brazed plate heat exchanger manufacturers tell you the advantages: 1. High heat transfer coefficient Plate heat exchangers are composed of inverted plates. The corrugated shape of the plates forms a complex flow path, which causes strong turbulence in the heat exchange medium, so the heat transfer coefficient is very high. 2. Compact structure and small footprint The heat exchange area per unit volume can reach 250m2. 3. Large logarithmic mean temperature difference and small terminal temperature difference Plate heat exchangers are mostly downstream or countercurrent, and the correction coefficient of the logarithmic mean temperature difference is about 0.95. The flow of cold and hot fluids in the heat exchanger is parallel to the heat exchange surface, and there is no side flow. The terminal temperature difference is small, and the water-water heat exchange can be lower than 1℃. 4. Easy to change heat exchange area or process combination If you want to increase or decrease the heat exchange area, you only need to add or reduce the plates; if you want to change the process combination, you only need to change the arrangement of the plates or replace a few plates to adapt to the new heat exchange conditions. 5. Low cost Plate heat exchangers mainly use metal plates, and the raw material price is lower than that of metal pipes. 6. Not easy to scale The fluid is greatly disturbed in the flow path, and fouling is not easy to deposit. 7. Easy to disassemble and clean

Brazed plate heat exchanger manufacturers tell you about the application of plate heat exchangers

Brazed plate heat exchanger manufacturers tell you about the application of plate heat exchangers. It is understood that the role of plate heat exchangers in heating is significant. The plate heat exchanger uses the heat of high-temperature hot water in the radiator to heat tap water, which can be turned on and heated immediately to achieve continuous hot water supply throughout the day. The water temperature can generally reach 30-50 degrees, which is enough for daily washing, washing and cooking. In addition, some professionals say that the use of plate heat exchangers generally does not affect normal heating. Truly achieve carbon-free heating. Brazed plate heat exchanger manufacturers tell you about the functional components of plate heat exchangers: 1, Heat transfer plate The heat transfer plate is the main heat exchange component of the heat exchanger. Usually, the corrugation is in a graphic shape. The material of the heat transfer plate is also different according to different fluid media. They are mostly made of stainless steel and titanium. 2, Sealing gasket The sealing gasket of the plate heat exchanger is mainly used for sealing between the heat transfer plates. Materials include: nitrile rubber, ethylene propylene rubber, fluororubber, etc. Different rubbers are used according to different media. 3, End pressure plates The end pressure plates are mainly used to clamp and press all the heat transfer plates to ensure that the fluid medium does not leak. 4, Clamping bolts The clamping bolts are mainly used to fasten the end pressure plates. Clamping bolts are usually double-headed threads. Bolts

From the name of the welded plate heat exchanger, we can see what this product is used for. After continuous improvement, this product has more and more functions. In order to let more people be familiar with it, the welded plate heat exchanger supplier will introduce some basic principles of the welded plate heat exchanger. If you want to know, let's take a look together, hoping to help you. The welded plate heat exchanger supplier said that the plate heat exchanger is a highly efficient and compact heat exchange equipment. Plate heat exchangers are increasingly valued for their high heat transfer coefficient, low pressure drop, compact structure, and easy maintenance. However, traditional detachable plate heat exchangers have limitations in structure, working pressure not exceeding 2.5 MPa, working temperature not exceeding 150 ℃, and the rubber gasket is prone to failure at high temperatures, and some application problems in specific media have not been solved. Therefore, in order to improve the working temperature and pressure of the plate heat exchanger and expand its application range, the welded plate heat exchanger supplier has developed and produced a fully welded plate heat exchanger. This heat exchanger can operate normally under extreme conditions of 300 ℃ working temperature and 3.0 MPa pressure. The welded plate heat exchanger supplier said that the fully welded plate heat exchanger has expanded

A comprehensive overview of the structural characteristics of brazed plate heat exchangers in Wuxi!

Wuxi brazed plate heat exchangers are a new type of high-efficiency heat exchanger. They are made by brazing a series of metal corrugated plates together, forming thin rectangular channels between the plates for heat exchange. Compared with conventional shell and tube heat exchangers, they have a much higher coefficient under the same flow resistance and pump power consumption, and there is a trend to replace shell and tube heat exchangers in their application range. The optimal design calculation of Wuxi brazed plate heat exchangers is to reasonably determine their model, process, and heat transfer area under the known temperature difference ratio NTUE. Brazed plate heat exchangers with plates as heat transfer surfaces have a compact structure and a large heat transfer area per unit volume. What are their main types? Let's find out together. 1. Spiral plate type: It consists of two parallel metal plates with a certain distance. Cold and hot liquids flow in the spiral channels on both sides of the metal plates. This type of heat exchanger has a high coefficient (about 1~4 times higher than that of shell and tube heat exchangers), a large average temperature difference, small flow resistance, and is not easy to scale. However, maintenance is very difficult. The operating pressure should not exceed 2 MPa. 2. Plate type: It is assembled by alternately stacking corrugated plates and sealing gaskets of a certain shape and clamping them with a frame. Cold and hot liquids flow through the channels on both sides of the corrugated plates respectively, and heat exchange is carried out through the corrugated plates.
