Plate Heat Exchanger

Our plate heat exchanger is composed of numerous plates, which are pressed by utilizing the metal sheets of various corrugated shapes. The fluid media flow in alternate channels is formed by these plate corrugations, and separated by the plate material and the sealing gaskets. Through these plates, it can achieve the goal of heat transfer.

Generally, the corrugated plates of our plate heat exchanger can be divided into straight type and herringbone type. They offer three main functions listed as follows.
1. The effective heat transfer area is increased.
2. After the plates are assembled, the multi-point contacts of two corrugated plates can enhance the rigidity and hardness of the plates, so as to withstand the large pressure difference between two channels.
3. The medium can be easily in a turbulent flow within the channel, which can slow down the formation speed of fouling.

Path Combination
Our plate heat exchanger is designed with diversified patterns of path combination, which can be realized by adoption of different assembly methods. The path combination can be categorized into single path, multiple paths, and a mixed path. It ought to be selected on basis of technical requirements.

With its temperature difference 1.8 times larger than the logarithmic mean temperature difference, the medium should utilize a suitable value of flow velocity from 0.3m/s to 0.5m/s between multiple-path plates. It is advisable to adopt two paths or multiple paths when the flow velocity is too low.

This plate heat exchanger can be divided into BR type and BRB type. With distinct specifications, it can be expressed as follows: B R 0.2 1.0 15 N VII
1. The letter 'B' represents the plate heat exchanger.
2. The letter 'R' means that the plate corrugation is herringbone with unequal cross-sectional area.
3. The digit represents that the nominal heat transfer area of each plate is 0.2m2.
4. The number means that the design pressure is 1.0MPa.
5. The number shows that the heat transfer area of the complete plate heat exchanger is 15m2.
6. The letter 'N' indicates that the sealing material is nitrile-butadiene rubber, for short as NBR. The letter 'E' represents ethylene propylene diene monomer, for short as EPDM.
7. The character represents the floor-mounted type movable pressure plate. The 'I' indicates the dual support framework consisting of the fixed pressure plates. (suspension type)
