In the industrial heat transfer field, plate heat exchangers and shell-and-tube heat exchangers have their respective advantages and limitations. As an upgraded iterative product, the plate & shell heat exchanger perfectly integrates the core strengths of both traditional devices. It solves common industrial pain points of traditional heat exchange equipment, including low heat transfer efficiency, poor pressure resistance, bulky volume and weak adaptability. Serving as a core energy-saving and high-efficiency equipment, it is widely applied in petroleum chemical, energy and power, refrigeration and energy storage, food and pharmaceutical industries, standing as the preferred solution for the upgrading and renovation of modern industrial heat exchange systems.

Adopting an innovative composite structure, the plate & shell heat exchanger is composed of a cylindrical pressure-bearing shell and precision corrugated welded plate bundles. It abandons the rubber gasket sealing structure of traditional plate heat exchangers and optimizes the cumbersome tube bundle layout of shell-and-tube heat exchangers, achieving dual breakthroughs in structure and performance. The unique corrugated plate channel design keeps fluid in a turbulent state throughout the operation, eliminating the low-efficiency defect of laminar heat transfer. Its heat transfer coefficient is 2-3 times higher than that of traditional shell-and-tube heat exchangers, with the minimum heat transfer temperature difference as low as 1-3℃, which greatly improves heat recovery efficiency and delivers outstanding energy-saving effects.

In terms of pressure and temperature resistance, this equipment features excellent working condition adaptability, making up for the shortcomings of ordinary plate heat exchangers. It supports a maximum design pressure of 80bar and a maximum operating temperature of 500℃, and can adapt to special ultra-low temperature and high-pressure working conditions as low as 20.3K, covering a wide range of temperature and pressure scenarios. The circular shell structure evenly disperses operating stress and avoids stress concentration. It has sufficient safety operation elasticity to cope with frequent pressure and temperature fluctuations in industrial production, ensuring stable and reliable operation and reducing equipment failure and shutdown risks.

The plate & shell heat exchanger boasts remarkable space utilization advantages. With a compact and modular structure, its volume is reduced by more than 60% compared with shell-and-tube heat exchangers under the same heat load, which greatly saves installation space and reduces factory infrastructure and layout costs. Meanwhile, it features low flow resistance with a pressure drop ≤80KPa, lowering operating energy consumption. It effectively cuts down long-term production and operation costs for enterprises, balancing economy and practicality perfectly.

Equipped with an all-welded sealing structure, the equipment avoids the aging and leakage risks of traditional rubber gaskets, delivering excellent sealing performance. It is compatible with various clean and slightly corrosive media, suitable for diverse complex working conditions such as oil and gas heat exchange, chemical fluid reaction, low-temperature liquefaction and food temperature control. Featuring a simple structure and easy disassembly and maintenance, it supports flexible adjustment of plate bundle specifications and customized design for different process requirements. With stable operating performance and long service life, it greatly reduces equipment maintenance frequency and consumable replacement costs, providing solid support for enterprise continuous production.

At present, plate & shell heat exchangers have been widely used in petroleum catalytic reforming, aromatic isomerization, synthetic ammonia chemical industry, LNG low-temperature heat exchange, power waste heat recovery, food pasteurization, refrigeration system evaporation and condensation and many other scenarios. With the comprehensive advantages of high efficiency and energy saving, high temperature and pressure resistance, compact structure, safety and stability, and low maintenance frequency, it gradually replaces traditional heat exchange equipment, becoming the core equipment for industrial energy conservation, consumption reduction and process upgrading, and the optimal choice for improving the quality and efficiency of industrial heat exchange systems.
