Introduction of heat exchanger

Heat exchanger, the heat fluid is part of the heat transfer to the cold fluid equipment, also known as heat exchanger. The heat exchanger occupies an important position in the chemical, petroleum, power, food and many other industrial production, its chemical production in the heat exchanger can be used as a heater, cooler, condenser, evaporator and reboiler, widely used.

Shell and tube type (also called tubular heat exchanger) is a shell and tube heat exchanger mainly comprises a shell, tube and tube plate and the head part, the shell is round, with internal parallel tube or spiral pipe, tube fixed at both ends of the tube plate. Two kinds of fluids, which are heat transfer in the shell and tube heat exchanger, are a kind of flow in the pipe, the stroke is called the tube. The wall surface of the tube bundle is the heat transfer surface.

In the development of stainless steel copper alloy composites, aluminum magnesium alloy and silicon carbide and other non-metallic materials have different degrees of progress, especially the rapid development of titanium material. Titanium has good corrosion resistance to seawater, chlor alkali, acetic acid, such as the enhanced heat transfer effect will be better, we have a better grasp of the processing of titanium material manufacturing technology.
