Shell and tube heat exchanger

The heat exchangers produced by our company can meet the ASME certification
Shell and tube heat exchanger (shell and tube heat exchanger) is also called tube heat exchanger. It is a partition heat exchanger with the wall surface of the tube bundle enclosed in the shell as the heat transfer surface. The heat exchanger has the advantages of simple structure, low cost, wide flow cross-section, and easy cleaning of scale; however, the heat transfer coefficient is low and the floor area is large. It can be made of various structural materials (mainly metal materials), can be used under high temperature and high pressure, and is the most widely used type.
Shell-and-tube heat exchangers consist of shells, heat transfer tube bundles, tube sheets, baffles (baffles) and tube boxes. The shell is mostly cylindrical, with tube bundles installed inside, and both ends of the tube bundles are fixed on the tube sheet. Two fluids, hot and cold, for heat exchange, one flows inside the tube, called the tube side fluid; the other flows outside the tube, called the shell side fluid. In order to improve the heat transfer coefficient of the fluid outside the tube, several baffles are usually installed in the shell. The baffle can increase the velocity of the fluid on the shell side, forcing the fluid to pass through the tube bundle several times laterally according to the prescribed path, and enhance the degree of fluid turbulence. The heat exchange tubes can be arranged in equilateral triangles or squares on the tube sheet. The equilateral triangle arrangement is compact, the fluid outside the tube has a high degree of turbulence, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning outside the tube, and is suitable for fluids that are prone to scaling.
The main control parameters of the shell and tube heat exchanger are heating area, hot water flow, heat exchange, heat medium parameters, etc.
