Plate heat exchangers are common equipment in many industrial sectors and occupy an important position in production. In recent years, the heat exchanger industry has realized the development trend of large-scale, high-efficiency, and energy-saving products in terms of products and technologies. The main problems existing in plate heat exchangers at present.(1) The gaskets of plate heat exchangers are easy to age and cannot withstand high temperature and high pressure.(2) The plate cooler cannot solve the problem of the medium with high viscosity.(3) Heat exchangers cannot meet the requirements of super large projects at one time and require a lot of cost input.(4) The current application range of plate heat exchange equipment is still too limited.
In view of the above main problems, the research and development direction of plate heat exchangers will be one of the fields in this field.
(1) Develop a new material of heat exchanger gasket. Continuously improve the vulcanization process of thermal experiments, which can meet the working conditions above 170℃ and gradually replace the shortcomings of cleaning and maintenance caused by full welding.
(2) Looking for a more suitable stainless steel material for the plate heat exchanger, designing the plate with the widest flow channel through a high-precision press, improving the corrugated structure of the plate, and adopting a "small stream" layout.
(3) For power plants, super high-rise buildings, and heating stations, multiple or more board replacements are required. We need to develop a larger plate exchange and increase the heat exchange area of a larger one-time installation. It mainly faces special and demanding working conditions for customer groups.
(4) With the fierceness of the industry, the current field can no longer meet the development of plate heat exchangers. We need to develop new equipment to meet the new industry and make non-rigid standards become rigid standards.
