In engineering design, heat exchanger selection often faces the problem of parameter matching: a single unit must balance heat exchange area, connection size, and pressure-bearing capacity, while the material must adapt to the medium characteristics. The BXS-120 brazed stainless steel heat exchanger is designed according to relevant standards, providing technical engineers with an evaluable solution.
The plate material of this model is 304/316L stainless steel, the connection specification is DN50, and the heat exchange area per unit is 4.5m². The overall dimensions are approximately 620×280×420mm, and the weight is about 48kg. The design pressure is 3.0MPa, and the applicable temperature range is -40℃~200℃. The combination of stainless steel plates and copper-based brazing filler metal is suitable for clean water, oils, and weakly corrosive media. If the medium contains chloride ions or acidic components, the risk of pitting corrosion should be evaluated, and the material solution should be adjusted if necessary. It is recommended to reserve a margin of more than 10% in actual operation to avoid long-term operation under extreme parameters.
For media such as clean water and oils, this heat exchanger can maintain stable heat transfer performance. When the medium is weakly corrosive, the 304/316L stainless steel plates provide a certain degree of resistance. For working conditions containing chloride ions or acidic components, a material compatibility assessment is required, and if necessary, higher-grade stainless steel may be selected or the brazing process adjusted. When selecting the model, engineers should calculate the heat exchange area margin based on the medium composition, working temperature, and pressure. The connection of this model is DN50, which facilitates pipeline connection and system integration, making it suitable for small and medium-sized heat exchange circuits.
